章 3644: SEX ED 101
It took me until the third day of college to realize that I might be one of those home schooled kids.
I'm sure you know the type. Even I did, but I never thought I was one of them. They're a little awkward and probably behind in some subject or another that their parents just weren't good at teaching. Maybe they don't wear all the new trendy clothes, but that's not too big of a deal. Most of all, they're innocent.
That last one was the kicker for me, the thing that started everything. Obviously I knew I was a virgin and all. But I figured most people were at least virgins at 18 like me, if not even more than that -- after all, who had the chance to kiss someone in high school, right?
Wrong. It turns out lots of people kissed in high school. And plenty did a whole lot more than that.
I was way, way more behind than I thought.
You can't blame me, though. At home, it was just really me and my twin Jason.
And I'll be honest: I never cared all that much about being a twin. It seems like twins usually go to one extreme or the other: either they're inseparable besties with a psychic bond, or they try to be as different as possible.
Maybe it's because Jason's a guy and I'm not, but we never really did either of those. We're close, but not overly so.
Jason was... Jason. That's really the best description I can give. Tall, skinny, usually rocking a mop of blonde hair that made him look a little like one of those designer labradoodle dogs. Interested in history, when I always had a passion for literature. Nice and all, but mostly just a constant and comfortable presence in my life.
(And before you say it: yeah, I know, Jason and Jill Janson. So silly. Wait until you hear about our parents Julie and Jake! Apparently they just couldn't get enough of the funny comments, so they decided to try to rival the Kardashians with their alliterative family naming scheme.)
Jason and I were equally surprised when we both decided to go to the same college, given our differences. I'll be honest: I was a bit surprised we even got into college to begin with. (Since, well, the home schooling thing.) But those acceptance letters and scholarship offers didn't lie, so I convinced myself we were better prepared than I thought we were.
And then school ended, and then summer was over, and then we were off.
I didn't meet my roommate until move-in day, but I knew Jason had been trading emails with his. Apparently the topic of siblings didn't come up, or they probably would've figured out that they were both twins, and that their twins were also rooming together.
It was definitely someone in the housing office's idea of a little joke, pairing us with another set of twins. Jill and Katie, Jason and Seth. How cute.
So as I went off to start my college life with my roommate Katie, Jason was doing the same with Seth. It was weird, knowing that two people connected as Jason and I were also moving in and unpacking in the very same rooms. Like deja vu almost, but experiencing the moment twice concurrently rather than reliving it.
I was halfway through unloading my panties when I stopped short: was this that psychic twin thing? That connection that I'd always heard about? Huh, imagine that.
--
Orientation went smoothly for about the first two and a half days. And then things took their first turn.
"Are you coming to the Lambda Kap party on Thursday?"
Katie didn't even turn to look at me as she spoke: her nose was still down in some textbook. "Work hard, play hard" was how she had described her attitude, which I could respect. Though I wasn't exactly sure what her words meant.
"The what party?"
She snorted. "Lambda Kap, the frat down on the corner of Oak and 5th? Seth has a buddy who's a brother, so I trust the guys."
A fraternity party? "Will we be allowed in? Will there be alcohol?"
That triggered a full-blown laugh from Katie, and she finally looked up from her book with amusement.
"Good one," she said. It would've been if I had been joking. But when I didn't reply, her eyes widened in horror.
"Wait--" Katie waved one hand vaguely. "Are you telling me-- Are you serious?"
Again, I remained silent. By this point, I had figured out my mistake: I knew people drank, of course, but I had figured it would be done quietly, illicitly. Not brought up so casually between new roommates! But I wasn't exactly ready to admit my misconception to this girl that I had known for a few days; that felt pretty embarrassing.
Thankfully -- I guess -- Katie took pity on me instead of mocking me.
"You weren't lying about being home schooled, huh?" she said, and I shook my head. "I kind of thought you were, since you seemed pretty well-adjusted this week."
I shrugged. "I wasn't lying. Definitely home schooled."
"Okay, just to be safe, I've got to check a few more things. First: do you know how babies are made?"
That made me roll my eyes. "They're brought by storks, obviously," I deadpanned. If she was going to ask dumb questions, she'd get dumb answers.
Again, home schooled, but not out of touch. I might not have known much about college culture, but my parents had given us the talk at least.
If I'm being honest, Katie hit on a sticking point, and I knew I was blushing a bit as I continued pondering babies. See, I had long had a bit of a fascination with pregnancy. Seeing a woman with her belly pushing out always made me feel a little woozy.
I think it was knowing how they got like that. Knowing that some guy had finished inside her, pushed it in deep. And now here she was, walking around proudly, showing the results of that successful rut to everyone.
Katie grinned at me. "Alright, fair. I'll stop teasing you."
She paused to think before continuing: "Look, it's no big deal if you aren't comfortable, but I think the party will be fun. Let's try it out, right? I'll stay with you the whole time."
I finally found my ability to speak, but the words that left my mouth surprised even myself: "Okay. Yeah."
--
Later that night, I did what any good, nerdy, unaware girl would do: some googling.
I looked up all the frats on my campus. I read some reddit threads about our party culture. I even looked up statistics about what percent of students drank and were virgins. (I did say nerdy, so you don't get to judge.)
It was a little relieving, having that knowledge. But now that I knew just how off-base I was before, I felt like I got off a little easy after the party conversation with Katie.
She had to think I was massively weird. And she just... let it go?
The answer was yes, at least for a day. I slept, went to classes, all that usual stuff. And when I got back to the room in the evening, Katie was perched somewhat expectantly on the edge of her bed.
"I've got a question for you," she started abruptly.
I nodded. "What?"
"Are you a virgin?"
I felt my cheeks flush immediately. What a personal question! Did she think I wanted to discuss this with her, a girl I had known for a few days?
But I knew my body language was already clearly giving away the answer, as I shifted my weight uncomfortably. And just a little, I was hoping she wasn't one herself, and that she could give me some advice or information.
"...Yeah. Are you?"
"Me? No. But I figured you were," she said, and I felt myself grimace a bit at that. She shook her head, continuing, "No, no, it's not a bad thing! You're just-- well. You know!"
"I'm what?"
"Innocent."
And here's the first moment when everything changed. If I had let the conversation end there -- if I had said something like "haha, yeah, I guess I am" -- then Katie would've dropped it, and none of this would've happened.
I know: butterfly effect, blah blah, you can never know the impact of a single decision. I'm sure about this one, though. I just know.
But I didn't say that. I said: "I'm not that innocent." In other words: I straight up lied, and Katie saw right through me.
"Yeah, right!" She was grinning now, a dangerous kind of grin that spoke of potential. I should've realized that then. "What have you done?"
"What do you mean?"
"First base? Second? Third?"
I took a moment to be thankful that those particular metaphors had come up during my late-night googling. But that didn't mean I had done them.
"I, uh-- Well."
"Wait, let me guess. First base with two guys, second with one."
"Not quite."
"First base with a guy you were dating. Over the clothes second base only."
"Uh, not that either."
"Just first?"
I scratched the back of my neck, pausing for just a beat too long as I tried to concoct some fictional man to talk about.
"No way. You've never done anything? And you just said you weren't that innocent?"
"I didn't want you to judge me!" I snapped. To her credit, Katie leaned back a bit, as if physically easing off the conversation.
"I wouldn't do that."
I felt bad now. She was right: she wouldn't. "I know. I'm sorry. I just thought everyone was as inexperienced as I am, and I'm realizing they aren't, and it's kind of freaking me out."
She did that dangerous smile again. "That's pretty easy to change, Jill."
"What do you mean?"
"You're a hot college freshman. Guys will be tripping over themselves to get with you. If that's what you want."
I had never really thought of myself as hot, and the descriptor felt uncomfortable. I didn't feel like I was anything special: I was average height with the kind of light brunette hair that just gave up on being blonde one day at around age eight. I had nice eyes -- light blue and big -- but nothing else worth calling out until you got down to my butt. That was really the only part of my body I really did like. Did that add up to hot? I wasn't sure.
But that wasn't even the important part: did I want to 'get with' some guy, as Katie put it? I didn't know that either. The thought was scary, but it wasn't unappealing.
I definitely didn't like being an innocent little virgin: I was an adult! Newly so, but still! My family was never those religious home school types, so it's not like I had any weird hang ups there. It was just lack of opportunity.
But the idea of doing it with some random man was less nice. I wasn't all too concerned about my virginity being some, like, big sacred moment, but I wanted it to be special anyway. I sort of just thought that I had held onto it for long enough that it might as well matter.
My dilemma wasn't something I particularly wanted to explain to Katie right then, so I shrugged limply. "I don't know what I want."
Katie stared at me and asked something that I thought was a complete non-sequitur: "what about your brother Jason?"
"What about him?"
"Is he a virgin too?"
I scrunched my nose. Uh, gross? "I assume so, but how would I know?"
"Do you two not talk about that stuff?" Katie looked surprised. "Seth and I share everything."
"Really? Even that stuff?"
"Of course. We're twins. It's normal." I wasn't sure about that, but at this point, I also just believed Katie knew better than I did.
"Oh. Well, Jason and I have never really discussed it. Do you really talk to Seth about that? Is he a virgin?"
"He's definitely not," Katie said quickly. It struck me as odd, her confidence, but I didn't think much of it. Clearly she wasn't lying: they definitely had discussed this.
She continued: "But you think Seth's a virgin?"
"He never had a girlfriend or anything, and it's not like there were a lot of options around for him. So... yeah."
Katie nodded and, without missing a beat, uttered the words that would change everything: "Fair enough. Well, I've got an idea."
With her words, she stood up and walked toward me. We were eye-to-eye, and I recognized the glint of a dare in her gaze.
"Rather than throwing you into the deep end," she said, "why don't we lean into the educational spirit here a little? We're at college, after all. Let's do some good, old fashioned education. Sex Ed 101, we'll call it."
To this day, I'm not sure what compelled me to agree. A lot of it was desire, I knew. I wanted these experiences. But part of it was the anxiety of my realization too: I wasn't just innocent. I was behind. And here was someone offering to help me fix that. Here was someone offering to de-home-school me, and I had to take that chance.
"I think I could do that," I said.
Katie clapped twice in quick succession. "Yay!"
--
And then... nothing else happened. The week continued on like I hadn't agreed to let me roommate teach me how to have sex, or something like that.
The night of the party arrived.
By this point, I was pretty sure I had gone through all the stages of grief about it. I considered telling Katie I didn't want to go anymore. I decided I'd only stay for a half hour then head home. But by the time evening rolled around, I came around once again.
I think it was Katie's own excitement that did it. Watching her get ready was like a whirlwind. She did her make-up first, expertly flicking on eyeliner and pouting as she rolled a bright red lipstick over her lips.
Then she turned her attention to clothes. She must have tried on at least 15 different outfits: she'd pull one shirt over her head, yank on another, stand in front of the mirror, and sigh. And then she'd repeat it, over and over.
I wasn't trying to stare, but it was fascinating. She was so feminine in a way that I had never been. Each time she'd tug off a shirt, her tits would bounce. They seemed huge -- melon-sized mounds pressed up and against each other by Katie's black lace bra -- and made all the bigger by the juxtaposition of her flat stomach.
No wonder she wasn't a virgin.
Katie caught me staring at one point and offered me a wink in the mirror. I flushed, cheeks first then all the way down my chest.
"I'm almost done getting ready," she said, "and then it's your turn."
I watched as she settled on a black tank top with straps that criss-crossed across her back. She looked good, the kind of hot that seems like it didn't require a lot of effort. She walked up to me, and I took that as my cue to stand awkwardly from my bed.
"I'm not sure what to wear," I admitted.
"I've got you covered!" She turned to riffle through the pile of tried-and-discarded options, producing another tank top and a plaid button-up. "I thought of this outfit when I tried this on. Here, look."
I let her dress me. If her hands touched me longer than was strictly necessary, I wouldn't have known, but I did know that her touch felt good and warm against my sides, scraping up to the edges of my breasts.
"There."
I looked in the mirror. The tank top was a halter, high necked in front and nearly backless. But I wore the plaid shirt over it, with sleeves cuffed to the elbow. The tank top was tight and showed off curves I wasn't aware I had, but it also was objectively a pretty conservative outfit.
I liked it, and I said that.
"Good," Katie replied, looking immensely proud of herself. "Then let's go."
--
The party was fun.
I hated to admit it, just a little. I had fretted enough that I sort of wanted it to be miserable, because then I could go back to being awkward little Jill and not have to worry about Katie being right about this, about everything.
But the party rocked.
True to her word, Katie stayed with me the whole time. And against my better judgment, I even drank. One beer, then two, then someone found some vodka.
I had never drank before, so the room got spinny quickly. I wasn't drunk -- far from it, really -- but I was pleasantly tipsy in a way I had obviously never been. And it was fun.
"Katie--"
I was going to tell her that I was tipsy, happy to be tipsy, excited to be tipsy, in love with life and this moment -- and then I saw Jason.
"Why is my brother here? He's not allowed here."
Katie laughed. "I asked Seth to bring him."
This perplexed me: why would Katie want Jason around? Evidently that confusion was written all over my face, because she answered my question without me even needing to voice it.
"We're going to have our first lesson tonight," Katie said.
I felt like a bucket of cold water had been dumped on me. I had sort of hoped Katie had forgotten about that particular conversation.
Jason noticed me then and walked over, with a guy I vaguely recognized as Seth trailing close behind.
Seth grinned at Katie, and I knew if I were sober, there would be more to it than just a simple smile. But I couldn't parse the emotion then.
"Glad you two made it," Seth said. "But I think it's starting to slow down. How about we head back to the boy's dorm?"
I looked at Katie, then Jason, then Katie again, unsure if we were really doing this.
She nodded. I felt myself nodding too.
I guess we were.
The boy's dorm was closer than ours. Katie's declaration about the lesson had partially sobered me up; the brief walk through the nice fall chill basically finished the job.
I felt like I was vibrating, and I didn't know whether it was remnants of alcohol, nerves, or some heady combination of the two.
Katie walked into the room like she owned the place. I, on the other hand, stood in the corner like the world's most boring houseplant. Jason lingered uncomfortably too -- even though it was actually his room.
"So..." I mumbled.
Katie gave me a reassuring grin. "You two look so nervous! Don't worry, this is going to be so easy."
My mind was absolutely racing: first, since when was Jason involved in this? That was my primary realization: not only was I going through with being taught about sex, but my brother was here too? Just great.
But then: easy? She thinks this is going to be easy?
I grumbled a noise of disbelief.
"We're just going to teach you how to kiss tonight," Seth said finally, and I looked up at him quickly. Clearly he was going to be my teacher, so I felt like I should get to know him.
He was pretty, I decided. He looked a lot like Katie: brown hair with the slightest curl, the warmest brown eyes framed by long lashes, and a dimple only on his right cheek when he smiled.
I pondered his words as I took him in. Kissing I could do. Maybe Katie was right: this could actually be easy.
I watched Katie step toward Jason out of the corner of my eye, and Seth stepped toward me. In sync, as twins should be.
"Is this okay?" Seth said, and I nodded. But he shook his head: "Say it."
"I want to kiss you."
Katie raised her eyebrows at Jason, and he followed my lead: "I really want to kiss you."
She giggled.
And that was that: Seth slid one hand under my chin and tugged it up, and we were kissing. He was soft at first, barely touching his lips to mine. I sighed, and everything changed. Suddenly his hand was grasping my back and his tongue was against my lips. It felt right to wrap my arms around his shoulders, so I did. His hand slid down to my ass and squeezed.
I gasped, which pulled us apart. I glanced over to see Katie and Jason in a similar position: he had his hands on her ass, she had hers tangled in his hair.
I turned back to Seth, who had caught me looking.
"Hot, right?" he murmured. He was right: it was.
I kissed him again.
--
Lesson one had been a thrilling success, I thought.
I had made out with Seth for what felt like hours, ending with me pressed up against the dorm room door as he kneaded my ass. And it hadn't felt weird to know that my twin brother had a girl backed up against a desk a mere meter away.
In fact, we ended up sleeping together. I mean, just sleeping. Obviously.
Because when we finally all pulled apart, we realized it was raining outside. Since neither Katie nor I particularly wanted to endure that trek home, it seemed reasonable to stay.
You'll sleep with Jason," she said, as if it were self-evident. But I hadn't shared a bed with my brother since infancy, and I wasn't sure I wanted to start now, right after we had all shared this intimate moment.
"Why?"
"Do you really want to wake up with Seth's morning wood pressed against your ass after you just kissed him a few times?"
Katie had a point. She usually did.
I curled up next to Jason tight to fit on the twin bed. He wrapped his arms around me.
"Sleep tight," he whispered.
--
The rain had stopped when we woke up, but it wasn't easy to get out of bed. It was warm and surprisingly comfortable to be wrapped in my brothers arms.
I looked over to see Katie and Seth awake and seated. They glanced at us and back at each other, as if sharing a secret.
"You two awake?" Katie asked.
Jason nodded sleepily -- I had thought he was still sleeping -- and my open eyes were proof enough for me.
"Good," Katie continued. "Because I think we can fit in a lesson 1.5 here."
I propped myself up on my elbows and blinked blearily: it was too early for her weird vague statements.
"I agree," Seth said. "Everyone kisses differently. So you've got to learn how to kiss with different people."
My brain wasn't processing well -- not that it was doing a great job with this whole sex ed thing to begin with -- so I just stared back at them.
"Are you saying--" Jason said, having made it further down the logic train than I did.
"It's just kissing," Seth said.
"What are you guys talking about?" I finally asked. Katie chuckled.
"You're going to kiss your brother."
I sat up fully. "I'm what?!"
"Like Seth said," Katie continued, as if I hadn't just screamed, "it's just kissing. We'll do it first, if it makes you feel better."
I didn't have much of an answer for that; Katie seemed to take that as acceptance, because she tilted over and captured Seth's lips with her own. They were seated side-by-side, so it was an awkward angle for a while until he grabbed her hip and pulled. Then Katie swung one leg over Seth's and straddled him.
An unexpected jolt of arousal hit me. I didn't know why. Was it their chemistry? The way they seemed to so neatly fit together? The thought intrigued me.
I finally looked over at Jason, who was staring rather intently back at me.
"Want to..." he started.
I didn't want to second guess myself, so I nodded quickly. I did want to. I needed to know.
I didn't straddle him, but we did turn to face each other. He was cross-legged, and I was propped on my knees, and he kissed me.
I was far from an expert, but I quickly decided this is what kissing should be. With Seth, it felt like he was controlling my moves as I submitted. And that was hot, but with Jason, it was a perfect give and take. When his lips opened, I was ready to slide my tongue between them.
He reached out to grab me, one hand fisting my shirt and the other palming my ass. We broke apart only to shift: he splayed his legs out in front of him, and I climbed closer.
Jason bit my lip, and I jerked my hips forward and mashed my clit right against the first boner I ever felt.
We wrenched apart. He stared, eyes wide and guilty.
"I'm so--" he started to say.
But before I could stop myself, I jerked my hips forward once more, purposefully. The end of his apology turned into a groan. We never broke eye contact, but Katie and Seth pulled apart then too and turned to us.
"Oh, look at them!" Seth cheered, he reached to high five Katie, as if celebrating our success for us.
Success -- I guess that's what you'd call that.
I was still frozen, pressed against my twin brother's hard cock and seemingly unable to do anything about it.
Katie didn't seem to recognize anything was wrong. She stood easily, happily, and dusted off her pants.
"Shit, Jill, we're both going to be late to class if we don't head out."
Class, right. I had forgotten about that.
So I stood up too, much more shakily, and looked back at Jason as we turned to leave.
"Thanks for the make out sessions, boys," Katie said.
Jason was still staring at me, unblinking and frozen. I turned and ran out of the room.
--
A week passed, and I managed to forget about the feeling of my brother, hard against me.
We had another lesson then. Handjobs. Second base.
This time, I got home from class to find Seth standing outside my room.
"We figured we'd do this one separately," he explained. "Since it's a pretty major jump."
Seth went first, twisting and pulling my nipples until I begged him to put his hand in my pants. So he did, spreading me apart and flicking my clit with his thumb as he slid two long fingers into me.
I had done this before to myself plenty of times, but it felt different -- good different -- to have a boy do it. Seth's weight pressing down on me, the way he murmured my name to look at him as I came--
It was good. Great, even. The best lesson yet.
And then it was my turn. I kneeled in front of Seth and slowly reached to lower his zipper, but I was caught by surprise: he wasn't wearing underwear. So when the zipper reached the bottom, his cock -- rock hard already -- sprung up and out.
I jolted back, and Seth cringed. "Sorry, sorry, I should've told you I go commando sometimes."
I shook my head -- it's alright -- and stared at the pole in front of me. I hadn't seen a cock in person before, but even I knew that Seth's was long. About as long as my forearm, in fact, with a flushed red tip.
My first thought was that it looked delicious.
I wrapped my hands around him and stroked softly.
"Harder," he said, and I complied.
"It's so soft," I wondered aloud. "But it's also so hard!"
He chuckled. "You're doing great. Just like that."
I liked Seth a whole lot, but when he came, I found myself wondering if every guy looked like that, all flushed and sweaty and groaning. I thought about his cum -- 'wasted' flashed through my mind unbidden, the image of where else it could be going a heady and forbidden thought.
He sat up after a minute, still looking a little punch drunk, and stroked his still-half-hard cock a few times.
"I'm going to skip ahead a lesson," he said.
"What do you mean?"
"I want to eat you out."
This was the first time I realized how much these lessons had done for me. Here I was, kneeling on the floor of my dorm room, jerking off a guy and having him ask -- volunteer, even! -- to eat me out.
And I wasn't freaking out.
I didn't say anything. I just stood -- shaky, for a moment -- and nodded. Seth guided me down to the bed and pulled my legs apart.
He glanced at me from between my thighs and winked, and I found myself thinking that he was so much like Katie.
Always with the winking. And that sharp tongue. Katie used it for words, but Seth-- he proved his prowess in other ways.
--
Another week, then two.
Then I got home from class to see Seth and Jason seated on Katie's bed.
"We've been waiting," Katie said, never one for any preamble.
"Why?"
"It's time for the next lesson, obviously."
Obviously. Yeah.
I busied myself with putting down my backpack and beginning to unpack the important belongings, hoping someone else would move or speak or... something.
"What are we doing today?" Jason finally asked.
Katie smiled sweetly. Too sweetly.
"We're going to suck you boys dry."
I swallowed hard.
Katie continued as if that were the most normal thought in the world. She leaned forward to give Jason a quick kiss -- which he eagerly reciprocated, from the looks of it -- and promptly kneeled down in front of him.
"Come on, Jill," she said, motioning toward Seth. To his credit, Seth looked a little awestruck too. His hands were clenched into the sheets, and his eyes were wide.
I felt my panties get wet. This was exciting, having a boy look at me like that. Like he wanted me. I knelt too.
It was easy to follow Katie, and it was even easier to forget that I was watching her do this to my brother. She palmed his growing bulge through his pants, so I did the same. Each guy gasped. Jason's head fell back.
After a minute, she reached for the button on his jeans, unsnapped it, and slowly -- oh so slowly -- drew down the zipper. Jason's bulge expanded dramatically now that it was only confined by his thin boxers, and I choked on my own spit, coughing once.
Just how big was my brother's cock? It looked huge.
I had Seth's cock out of his pants at this point and was stroking it lightly, getting him ready and hard, but I was torn away from my actions by a groan. My brother's groan.
I turned to glance and was rendered speechless again. I had been right: it was enormous.
Not long, or at least not nearly as long as Seth's. From what I knew, it looked within the range of average. But it was wide, thick as a can. The head flared out like a mushroom top, but the base wasn't much narrower.
The shape of a cock had a purpose. It had to fit, sure, but it also had to do its job: pushing all that seed up inside. I knew then suddenly that both Seth and Jason had utterly, completely perfect cocks.
Seth's would go so deep that it could spurt its cum right where it was needed most. And Jason? I wasn't sure any cum could possibly ooze out around that monster. Both would make their cum get sucked right up into any woman's womb.
I watched as Katie's eyes widened. She had seen this cock before, jerked it at least once from what I knew, but its size was evidently still shocking. She wrapped a hand around the base of Jason's cock.
Or-- Wow. 2/3 of the base of Jason's cock, since that was as much as her hand could cover. And that was a generous estimate.
Seth was squirming before me, so I focused my attention back on him.
I knew this lesson was coming, so I had done some research. I kissed the tip of his cock lightly. Then I gave a firm lick all the way from the base back up. I sucked the first few inches -- all I could fit without gagging -- and used both hands to cover the generous remainder.
I sucked gently, and Seth's head fell forward with a groan. His back hunched, entire body limp as he watched me with half-lidded eyes.
I couldn't stop myself from glancing over at Katie. She had her mouth open impossibly wide, trying to fit Jason between her lips. And though she wasn't able to fit much, he looked like he was enjoying it: his hands were gripping the sheets so hard they were pale, and he was biting his lip.
We both sucked happily, loudly until each guy came in our mouth with a muted groan, as if they had been punched.
Then Katie spoke: "I hear you two have been going ahead of the plan, huh?"
I felt guilty all of a sudden: were we not supposed to do that? Then I felt stupid. This was all so that I could be comfortable with my sexuality, right? So of course it was okay.
Oblivious to my dilemma, Katie continued: "Jill got eaten out, but I haven't yet. And since Jason looks a little dead to the world right now..."
Which, to be fair, he did. He seemed half asleep, like Katie had sucked the life force out of him through his dick.
"... I guess Seth will have to do it."
Wait, what?
I watched, shocked, as he immediately laid back. She pulled off her leggings and panties and climbed right up onto Seth's face.
"Whoa," Jason mumbled, and I looked over at him. He had found the power to lean up on his elbows, and was turned to stare directly at Katie's pussy.
I had a realization then, one I probably should have had much earlier: these lessons were not the first time Katie and Seth had fooled around, and it likely wouldn't be the last.
--
I already felt different. I felt like the whole world could see it too, that each and every person I walked by would know somehow that I sucked a dick last night.
It was like I was high on the memory, the thrill of the moment I had taken Seth into my mouth. Or that's what I told myself, because every time I imagined the moment -- and I imagined it a whole lot -- it wasn't really Seth I was picturing.
He was hot, don't get me wrong. The vision of the way his head had fallen forward as I took him in my mouth, as if he were collapsing in on himself, was enough to make me dizzy with want.
But mostly, I thought about Jason. The way he had been gripping the sheets of the bed with both hands like it was his last tether to earth.
How his cheeks had flushed a deep red first, then his neck, then his whole body, until all of him matched the pink of his cock, thick and slapping up against his stomach the second Katie had pulled down his boxers.
How he had sighed when Katie sucked the tip of him gently.
I refused to believe that I was thinking about my brother -- my twin! -- like that. Clearly it was Katie that was causing these thoughts, since she was so good at sucking dick. I was entranced by her and the sheer power she seemed to hold.
Not Jason. Absolutely not.
Sitting through my classes the day of the next lesson was a unique form of torture. Every time I shifted, I felt a pressure between my legs. Crossing my legs, pressing them together -- it eased the ache slightly at first, but then it suddenly caused it to grow. I kept shifting in my chair, praying for the afternoon to pass by faster.
After all, I had one more thing to learn that day even after classes were done.
At last, my final professor dismissed us. It was winter, so the sun was already beginning to set, and the sky was a pretty pink-grey. The dusting of snow still on the ground made everything quiet. The world seemed expectant.
I considered straight up sprinting across campus, but I didn't want to seem out of breath or sweaty -- yet -- so I restrained myself. I must have looked ridiculous, all but speed walking up to the girl's freshman dorm.
I remembered a conversation I had with Katie the prior week as I was entering the building. She had one request for me: go to the pharmacy and pick something up for myself. I had nodded my agreement.
"You will?" she confirmed.
"Of course."
With all my midterms going on, I hadn't had the time. And I didn't think much of it: I figured she meant condoms, which I knew the guys were buying too. Katie was always so thoughtful, wanting us to have back-ups.
--
Finally, it was time. Even though Katie told me there was one more lesson after this, I knew this was the one that mattered. This one was sex.
We decided to do it all together. We had briefly considered separating off again, but I didn't like that idea. I told myself it was because I wanted Katie there as a guide.
So Katie and I went to the boys' room right after sunset.
I thought this lesson would be the most awkward of all, especially since Jason and I had done plenty of weird standing around and second guessing in the lead ups to every other lesson. But it wasn't.
It was like all this work finally clicked, and we shed our home schooled selves at last.
I straddled Seth's lap as we kissed. His hands gripped my ass and pulled me again and again into his hardness.
"I can't wait to fuck you," he muttered, and I whimpered in response.
He pulled off my top and my bra, and his hands immediately flew to my tits. I managed to get his shirt off too, and then I went for his pants without missing a beat.
He chuckled. "You're probably going to have to get off my lap for me to do that."
I rolled over, laid on my back on his bed, and took the moment to glance across the room.
Katie was naked except for her panties, and she was holding her own breasts up as she grinded on my brother. She twisted her nipples and groaned.
"Jason, let's fuck already," she said. He nodded quickly and went to tug down his shorts. He took his boxers down with them, and his cock sprang up.
Seth's pointed outward at an angle when it was erect, but Jason's went straight to his stomach. And once again, I felt my mouth dry at the sheer girth of it.
I saw Katie had a moment of doubt as she reached for a condom and found it hard to stretch over Jason's length. I could see it in her eyes, the realization that that thing was going up inside her in a moment. She took a deep breath.
Seth had stripped off his pants and put on a condom too. He turned his attention back to me, pulling down my shorts and panties.
"Want me to eat you out?" he said.
It was a tempting offer from a guy with a very talented tongue. But I looked down at where his cock was sticking so far out from his body, and I found myself shaking my head.
I was wet -- wetter than I could ever remember being -- and glancing back at Katie and Jason made me even more so.
I was ready.
"I want you inside me," I said, and Seth grinned and nodded.
He crawled over me. I looked over: Katie was straddling Jason, having decided that she should control the speed at which he entered her.
Call it fate, call it that psychic twin thing, whatever. But Seth stuck his cock into me at the exact moment Katie lowered herself onto Jason. And right then, Jason looked up and we made eye contact.
All four of us moaned out in unison, a chorus of "oh fuck" and "you're so tight" and "how the fuck are you so big" and "I feel so full."
Then there was silence, a pause in the room as we each took a deep breath.
Katie broke it: "fuck me."
And both boys did.
I watched as Jason pushed up into Katie and her face twisted into some mix of pain and bliss. He was somehow fitting in her, stretching her so far open as he went.
Jason watched as Seth bottomed out inside me, going so deep that I was sure he was going to pop right out of my throat. Then he pulled all the way back to the tip and slammed it back with enough force to push me several inches up the bed.
"Fuck!" I yelled.
Seth was unrelenting, filling me over and over.
"I can't believe my cock is the first one you've ever had inside you," he said. "That's crazy. No one's ever been this deep in you before."
"It feels so good," I groaned back. "Doesn't it feel good?"
"So good, Jill. You're a natural. You're taking it so well."
"It -- uh, fuck. It's pretty big."
"It sure is!" Katie chimed in. "Not a lot of girls can take Seth's cock, but you're taking it all."
I looked down then to see where Seth's length was sliding into me. I watched it pull out -- it seemed endless -- and then slide back in until his balls slapped against me.
I was grunting with each stroke, building up toward what I was sure was going to be an incredible orgasm.
But something was holding me back. I barely noticed the condom's drag within me, but I knew it was there. I knew Seth would come and it would inflate and none of it would end up inside my pussy. Honestly, it was disappointing, even if it was necessary.
And then I heard Jason: "Jilly, look at me."
I looked over. He looked almost pained.
I couldn't help myself from voicing what I saw: "Whoa, Katie, do you have that all in you?"
"Aren't you impressed?" she said, clearly proud. "It's probably a good thing you two were so sheltered. I think this cock might've killed someone else."
Each word Katie spoke was punctuated with a sigh as Jason pushed up into her.
I stared at Jason, and he stared right back. Matching blue eyes meeting, knowing exactly what the other was experiencing.
I had never felt that before.
"Can you come, Jill? Please?" Jason's voice was almost broken, pleading.
That and Seth's continued assault on my pussy was enough to send me over the edge. I writhed as my orgasm overtook me, reached up and pulled Seth down onto me as wave and wave of pleasure crested over me.
"Too tight, I'm gonna--" Seth groaned. Even through the condom, I felt his cock thicken and pulse, jerking against my cervix. It was easy enough to pretend his cum was in me, filling me, breeding me.
It seemed like the sight was too much for Jason to handle too: he pushed up one final time and, with his hands on Katie's shoulders, pulled her down in unison. He broke with an almost silent sigh.Katie, on the other hand, wasn't silent. "Oh fuck! I can feel it all! Fuck, you're cumming so much. You better not break that condom with all your cum. I bet you'd get me so pregnant. I bet you'd send all that sperm right into my womb."
Our orgasms fading, we fell against our partners. Slowly, the guys withdrew and carefully tossed their sagging condoms. And then we all fell asleep.
--
Katie was waiting for me when I got back from class the next day, just as I expected.
"So?"
I didn't even know where to start, so I shrugged aimlessly and happily. I couldn't stop smiling.
"Good right?" she asked.
"So good."
"What was the best part?"
"I-- don't know."
But I did: the best part was that moment of eye contact with Jason, knowing that he would do anything for me and I for him. I couldn't tell Katie that, though.
"I think it was the moment both guys got fully in us," I said. A close second to the real answer, to be fair.
Clearly it was the right thing to say, because Katie nodded vigorously.
"I can't believe we both have brothers with such massive dicks. Like, what are the odds? You were a champ, for real."
"I'm still a little sore, to be honest."
"Do you think I'm not? You saw Jason's cock. That thing should be labeled heavy machinery!"
We laughed together, and then I paused, earnest. "Katie, uh... thank you. I mean, for the lessons. I think they were helpful."
She wrapped her arm around my shoulder. "Jilly bean, it's my pleasure. But we're not done yet, remember."
I couldn't imagine what we still had left to go.
--
It was almost a month before the grand finale. School, then a particularly bad period on my part, then a bout of the flu on Seth's had all gotten in the way.
I wasn't even expecting it when it did happen. I wish I could say I had forgotten, but I was tantalized by the thought of what this last lesson might be.
For that whole month, I found myself reliving our group fuck during every moment I had alone.
I would start off thinking about Seth. Obviously. The way he sunk into me, the way he touched a depth within me that I didn't know existed, the way his whole dick pulsed as he came.
But every time without fail, when I closed my eyes, I remembered the way Katie's folds looked stretched around Jason's cock. The way she bore down to fit more of him inside. I imagined what that would feel like, and I came.
Every other lesson had taken place at night, when the sun had set and it was easy to blame our actions on the hour.
I woke up to Katie dressed in the room one Sunday morning and bouncing with nervous energy, and I knew this final lesson would break the mold. The boys arrived minutes later, with me still barely out of bed.
"You couldn't have let me get ready?" I grumbled.
"Doesn't matter, because you're getting naked," Katie said.
"What?"
"You too, Jason," she added.
We both stared: where was she going with this?
"Come on now."
So we did. We stripped, and Katie and Seth stood across the room from us fully clothed.
"What now?" Jason said nervously.
"Now we touch you."
They approached us, but their touches were light, unsatisfying. Seth stroked my breasts gently, barely brushed over my nipples. He stroked one finger over my folds but not in them until I groaned and begged: "come on, Seth, what are you doing?" But even then he didn't put even a single finger inside me. He swiped around my clit, so close to what I needed.
Jason seemed similarly frustrated: Katie was paying more attention to his thighs than his cock, rubbing her hands everywhere except where he wanted them most. Every few seconds, she'd ghost a finger along his length or across his tip, and then she'd retreat.
I was quickly growing frantic. Was this their grand finale? Torture?
"Do you think they're ready?" Katie asked.
"For what?" Jason said, but she ignored him.
Seth nodded. "I think they're ready."
They stepped back, and I held back a groan.
Katie grinned that devilish grin that got us into this whole mess. "Now you're going to watch."
I'm not sure I've ever seen someone move so fast as Katie did when she pounced on Seth. They stumbled back to her bed, landing with him above her.
Jason was stroking his own cock at the sight. It wasn't a bad idea, self satisfaction, but I had to know where they were going with this.
"What are you two doing?" I all but yelled. "And what are we supposed to do?"
At that, Seth looked up. "You two can do whatever you want. Only rule is that you've got to stay naked."
I looked at Jason. I wanted Jason.
"We've already made out once," I offered. Like it was at all the same.
But he went along with it. Maybe he wanted me too. "Yeah. And we've seen each other naked. Combining those things isn't too bad, right?"
"Right." In that moment, I really believed that. We'd stick to making out and watching, get off, and that would be that. We'd have done the final lesson, the last big test of our wills.
"Uh, okay then."
Jason sat on the edge of his bed, uncertain. He looked nervous, somehow small, despite the very, very big pole sticking out from between his legs.
I knew I needed to help him. As a sister. As a twin. We had made it this far together, but we were both unsure of this final leap, whatever it might be. One of us had to be brave, so it was going to be me.
I pushed his shoulders until his back was against the headboard, and I climbed over him.
"See?" I said. "We got this."
For a moment, I turned to watch Seth. He had reached out to cup Katie's tits in his hands through her shirt, and they seemed to overflow from his grasp.
He was rutting into her now, hard. He'd piston his hips down and she'd grind hers up, and they'd meet with just a few layers between them. Each time they separated, I could see the dramatic bulge in his shorts, big enough to make the fabric of the legs shift up a bit on his thighs to accommodate it.
Then Jason grabbed my chin with one hand and tugged, and my gaze fell back to his. Without breaking eye contact, he slid his free hand up my stomach and palmed my breast, and I groaned unwittingly. His hand was so warm, fingertips burning prints into me that sent heat straight down to my center. The sound clearly encouraged him: he immediately pinched my nipple and leaned up to kiss me intently.
I had been hovering over Jason, but supporting my weight quickly became too much, and I collapsed down onto his thighs. The mere inch of space between us hadn't been a lot to begin with, but it had been enough: I wasn't aware of just how hard he had gotten. And then suddenly I was extremely aware, as my clit landed against what felt like a steel rod.
We were naked: Seth & Katie had told us to be, after all. Thankfully, Jason's cock had its ever-present curve, and it was stuck up against his belly versus out where my pussy had just fallen.
I had known he was thick after watching him stretch Katie's pussy open, but I hadn't realized how thick until now. His length forced my folds apart and rested right in between them. I felt his cock throb.
We both froze. Jason jerked back slightly, panting. The movement made me slide against him. I was so wet, and he felt so hot against me. I couldn't help it: I pressed down just a bit. It only made the ache worse.
Our eyes -- both that same shade of blue -- met, wide.
"Jason, I--"
He spoke at the same time: "oh shit, I'm so close already--"
And then: "oh fuck." It was a male voice, and for a moment, I thought it was Jason's again. In my frenzy over my brother's cock, I had forgotten that there were other people in the room.
But then a feminine "my brother feels so good" followed, and Jason and I both spun our heads over to the other bed.
I'll tell you what I expected: Seth with his hand down Katie's jeans, pushing his thick fingers into her. He'd put his weight into it, hitting that perfect spot over and over because they were twins and he just knew her body like that. And she'd wrap an arm around his shoulders to hold him close as she writhed and writhed and finally came.
I imagined maybe she'd have a hand palming his shorts too, rubbing his length over and over, returning the favor as best she could as sensation overwhelmed her.
And I figured if I got really lucky, he would have taken off her shirt so I could see her tits bounce as she moved. I mean, that's the obvious thing to do with his other hand. That's what I would do if I were him. He'd pull and knead her breast, flick her nipple until it stood firm and sensitive.
That's not what I saw when I turned my head, though.
Well, I first noticed that I was right about her tits: her shirt was pulled just over them, forcing them together a bit and making their bounce seem that much bigger.
But then I noticed the rest: Seth had every single inch of his cock stuffed up inside his twin sister Katie.
He pulled it out slowly, and I stared as each inch slipped free, glistening with her wetness. It looked like they were screwing gently for those first few moments, until he got out to just the tip and slammed it back into her.
Her head flew back against the pillow, and she gasped again: "oh, so big so big so big."
But she was taking it all. I could see Seth's hand between her thighs, rubbing her clit, and a few inches above that, I swear I could see her stomach bulge a bit with each thrust. He was that deep inside her.
I heard Jason mumble "are they--" in a sort of dazed voice. But I was so intensely focused on what I was watching that I barely processed his words, and I certainly couldn't bring myself to respond.
Katie was holding on for dear life, both arms wrapped around Seth's back, nails clawing into him. I was sure he'd have scrapes everywhere later, but he didn't seem to mind. If anything, it encouraged him, and he pounded into her again and again.
"Harder, baby, harder," she began to chant. So Seth gave her a particularly hard thrust that made the headboard slap loudly into the wall behind it, and Jason and I both seemed to break out of our trances at once.
That would've been great, had we not seemingly decided on opposite courses of action. See, I decided to lean back, but he decided lean forward. And because I had been balancing most of my weight on my hands on his chest, that didn't really work out.
His movement made his dick jut out, no longer firm against his abs. And I successfully leaned back for a moment before losing my balance and falling back against him. Only this time, the tip of his cock -- oh-so-thick and dripping with pre-cum -- was exactly in the right position.
And that's when it happened.
I knew Seth had told Jason that holding off on cumming for a few days was a great way to massively increase the size of his load and that Jason had taken to doing that occasionally. I also knew that he came a lot to begin with.
I knew that my period had ended two weeks and one day ago, and I knew I had woken that morning to that sharp pain in my lower abdomen. I had seen a doctor for that once during my early teen years; since then, I knew to expect the ovulation pain monthly.
So I landed back on Jason, and Jason reared up into me, and suddenly about three inches of his thick cock were up inside me.
I had never been stretched even close to that far. He felt like a fist reaching up inside of me, pushing me wide open. I shrieked and leaned forward, but all the motion did was drive the rest inside me. I looked down: my folds were stretched obscenely, and all I could see was the very base of him, where his cock ended and balls began.
My brother's dick was in me. Oh fuck, oh fuck.
My hands, still on his chest, rose to his shoulders and gripped hard. I looked up at Jason in shock, about to pull myself off of him and apologize frantically.
Jason had been close before -- he had said as much. Even just the mere slide of me against his length had left him trembling. Apparently watching Seth and Katie rut had put him even closer to the edge.
Because just as I looked up at him in horror, his eyes slid shut and he groaned a quiet, "oh, Jill."
I thought his dick had been hot, like burning flesh against me and then inside me. I was wrong. He pushed up further -- not that there was anything more to shove inside me -- and sighed as he came, and I then understood what true heat felt like.
His cock gushed inside me, throbbing once, twice, again. It kept going, and each pulse pushed a wave of hot cum against my walls. I had been right: his girth was so wide that little cum could escape. A few drops squeezed past him and out, dripping down around my thighs, but he kept cumming, and I felt it all in me, trapped and beating up against my cervix.
My body was overwhelmed. I had orgasmed many times before, but this was a whole different level. Somehow in that moment, I knew that my twin brother was creating new life inside of me. Somehow I knew that those sperm shooting up into me were sneaking through and racing toward the egg that awaited them. It was too much. So instead of pulling myself off like I had intended, I came harder than I had ever cum in my life and let my whole weight drop against him.
Distantly, I heard Katie gasp. "Oh shit, Seth, look. They're fucking."
Seth must've turned his head, because he let out a low, deep moan. The steady beat of his thrusts didn't stop, though, and a moment later he choked out: "Fuck, I can't hold it back, I'm cumming!"
I knew what that felt like after our last lesson: Seth's cock had felt like it was up in my guts, probing deep inside me in a way that made my body's natural urge to procreate run wild. 'Fill me,' my body had seemed to scream. 'If you come this deep, you'll seed me so good.' But Jason's cock felt like it was made for my pussy alone, like it fit perfectly, exactly.
It made that urge become a real possibility, and then a reality.
There was one more thrust, and then silence as Seth filled Katie up. I knew what that felt like too, even though we had used a condom: Seth's cock grew thicker, and he pushed every millimeter inside you as he came.
A condom. Fuck.
I quickly lifted myself onto my knees and let Jason's softening length slip from me. A torrent of cum followed, more than I had ever imagined could fit inside me. It dripped and puddled around the base of his cock.
He looked dazed and somewhat braindead, eyes wide and glazed, oblivious to my panic.
Seth and Katie were oblivious too. He nuzzled into her shoulder as she cooed at him: "thank you, baby. That was so good."
He slipped from her, and a trail of cum followed. A stream, compared to my dam, but my thought in the moment was that at least they hadn't used a condom either.
I turned back to Jason. "You came in me?!"
That made him awaken. "I-- Fuck! Fuck. I didn't mean to. I'm so sorry, I--" He shook his head, not knowing what else to say.
No part of me remembered the pharmacy conversation from months ago. No part of me considered birth control at all, ever, during any of this, which meant I certainly didn't assume that Katie was on it. But of course, she was.
Katie, however, did remember the pharmacy conversation. In particular, she remembered my agreement. She assumed I had gone. She assumed I was protected.
So she laughed, a light giggle that only comes after a great orgasm. "Oh Jilly bean! You officially get an A+ in sex ed."
I was so overwhelmed, distracted by the continued drip of cum from between my legs (how was there still more?), so I stuttered out a "Huh?"
"We never thought you two would fuck! We just wanted to watch you dry hump a bit. That was going to be the big finale: some brother-sister rubbing action. But you two went above and beyond, and you get major extra credit for that."
Seth was watching us with a grin on his face, clearly equally unperturbed. And Jason, despite his panic mirroring mine, was gently palming my ass.
My realization had somewhat thwarted my post-orgasmic bliss, but I had to admit I still felt pretty great. Each drip of cum made a shiver run up my spine, and I couldn't tear my eyes away from the similar state of Katie's pussy.
Plus, well, Katie and Seth had fucked too -- and clearly not for the first time!
So I made what would end up being my final and biggest decision: I decided it wasn't a big deal.
After all, who gets pregnant after precisely one thrust of unprotected sex?
I leaned down into Jason, resting my weight on his chest. He wrapped his arms around me.
"Proud of you," Katie said, and I raised my head just enough to see her wink.
--
The lessons stopped after that. Katie hadn't lied: we had passed with flying colors.
I went from a crazed, sex lesson fiend to, well, Jill. And Jill was still as awkward as she had ever been, so I definitely wasn't getting laid on the regular.
The semester was coming to an end, and I had an exam in nearly every class. So when my period didn't come, I didn't even notice it. I would have thought it was stress related if I had.
We went home for the holidays, but I spent Christmas Eve with some sort of stomach bug, puking up the whole wonderful meal my parents had cooked. I remained nauseous through New Years, and I decided not to drink in case it set my stomach off again.
My parents urged me to see a doctor, but I was sure it was food poisoning and brushed them off. I blamed it on our neighbor: she was getting pretty old, and I was sure I had seen some under-cooked chicken in the pot pie she had brought over.
I wondered constantly if Jason and I were ever going to acknowledge what happened. But he didn't seem to want to, and I wasn't sure how to bring it up.
Mostly I wasn't sure what I wanted, honestly.
I didn't particularly want to just say "hey, remember that time you stuck your cock up in me? That was weird!" since that felt obvious.
So it seemed like I should only bring it up if I wanted to do it again. And did I?
The obvious answer was yes, but I wasn't sure if that was Jason-specific or just my newfound desperate need for dick. I had gone from zero to one hundred pretty quickly, and the descent back to zero had been equally as abrupt.
At night, I was willing to admit I wanted Jason. I'd push my hand between my thighs and slip two fingers into myself. Previously, that would've been enough, after curling them just right. But then it stopped being enough, and I had to put a third finger in, feel myself stretch like I had when my brother was throbbing inside me.
Every time I did that, I would cum immediately, shaking as I stretched myself open again and again.
But in the daytime, that was harder to acknowledge. I knew I wanted to fuck, but I couldn't admit I wanted Jason, only Jason, my twin brother Jason.
--
By the time our break was ending, I had gained enough weight that some of my sweaters rode up at the bottom, showing a little of my midriff over the rise of my jeans. I thought it was weird, given how little I had been eating. But Christmas is Christmas, and I figured there had been plenty of sweets around during my periods of health.
And Katie had told me that the cropped look was in, so maybe I'd be stylish for once. I was a little excited at the thought.
Soon enough, spring semester was beginning. I got back first, and I had unpacked and rested for a day when Katie returned.
I was on the bed in pajamas -- a tank top and shorts -- when she walked in, dressed for the trip in long pants and a coat.
She stared. "Jill, what the fuck?"
Confused, I stared back. I assumed she was talking about the difference in our outfits.
"I got back yesterday," I explained. "So I'm already unpacked."
She didn't appear to register my words at all, didn't even blink. Just stared. And then: "When the fuck were you going to tell me you were pregnant?"
--
If I had learned one thing over my first few months of college, it was that Katie was usually right.She certainly was in this case.
I went to the student health center for the first time ever. I walked right by the pharmacy with a sinking recollection of Katie's request that I had never obeyed, and I went up to the nurse. One test later, and it was confirmed.
My twin brother had knocked me up.
--
Jason took it well, all things considering. He stared at me for what felt like minutes on end and mutely put both hands onto my lower stomach. He breathed deeply.
"Are you okay?" he managed.
"I think so," I admitted. Maybe I shouldn't have been okay. But I really was. I had wanted my first experiences to be special, and what was more special than having the guy you know best make a baby inside of you?
"Okay. If you're okay, then I'm okay."
I laughed a little at that. "Of course. We're twins, after all."
--
My belly grew quickly. Too quickly. I went back to student health for my first scan and promptly found out that I had two babies growing in me.
"Twins?" I gasped.
"Looks like it," the doctor confirmed. "Twins can run in families, so it's not entirely surprising." The doctor looked at me, and then at Jason.
I had brought Jason with me, having quietly told the doctor that I wasn't sure who the father was and wanted my brother with me during this tough time. The doctor had easily agreed.
I turned to look up at Jason now, only to see him already staring down at me. His eyes were wet with tears.
As soon as we left the doctor, his hands were on my stomach, cradling its impressive curve.
"I can't believe it. We did this."
"You did this," I corrected, but I was grinning. "You and that fat cock of yours.'
He had the decency to blush. "I really am sorry I came in you."
"I told you, it's alright. It's kind of flattering, actually, that you were so turned on you came after about one second inside me."
He breathed out a quiet laugh. "You're really okay with all this?"
"I am."
He nodded, and then repeated: "We did this. You and me. We made two little people, just like mom and dad made us."
The thought wasn't just hot -- it was overwhelmingly so. The idea that we had been formed in a womb together, grown together, and that he had placed himself deep inside me to continue the cycle was the most beautiful thing I could imagine.
--
It was about three months into my pregnancy that Katie sat me down.
"I have an idea," she said. I was a little nervous, since the last time she said that I ended up super knocked up, but it's not like there were any more potential pregnancies involved.
"Let's hear it."
She proceeded to explain that -- technically speaking -- I hadn't really fucked either guy.
See, in Katie's mind, sex with a condom wasn't real. She said she wasn't planning on telling me that ever, since it was just her opinion, but now it felt relevant. So that's why I hadn't fucked Seth.
And then Jason was obvious: he had stuffed that huge pole in me and cum immediately. That didn't really count. Even I could agree with that.
Because I was already massively pregnant, this was the perfect opportunity, Katie reasoned. Essentially, it was time for Sex Ed 102.
There was one other pertinent piece of information here: pregnancy had made me incredibly, insatiably horny. And masturbating really wasn't doing it for me anymore.
So I said yes.
Katie clapped. "Good!"
She stood up, and I watched in confusion as she walked over to the door. Was she leaving?
She pulled it open, and Seth and Jason were standing right there.
"We figured you'd say yes," Seth said.
They were both in coats -- required to go outside, but unzipped now-- but even the layers couldn't hide the way their bulges strained against their pants.
Unconsciously, I licked my lips. And much more consciously, I nodded slowly and dragged my eyes up to Jason's.
"What are you waiting for?"
--
I decided I liked being pregnant.
And why wouldn't I?
My stomach continued to grow. I bought plenty of maternity clothes, of course, but I secretly loved wearing my old shirts. They didn't fit, of course: the fabric was stretched taut, many riding high enough to show my popped belly button. I loved wearing one under an unassuming coat, sitting in the front of a lecture hall, slowly unzipping, and watching as every man did a double take.
I felt absolutely gigantic, but I loved every second of it, especially once we found out we were having one boy and one girl.
Every inch I grew was a reminder of how big Jason's cock had felt in me and how I had known that his huge cock head was keeping every drop of cum in me to knock me up right then and there.
Every kick was a question: is that mini-Jason, or mini-Jill? I hope they're getting along in there, because we're going to want them to get along really well once they're grown up out here.
My tits grew too, big enough that they fit perfectly in the palm of Jason's hand. Once again: like our bodies were made for each other.
That was all nice, but what was really great was the sex. I got fucked at least once a day, sometimes once by each of them.
Seth liked taking me on all fours with his long cock shoved inside of me, and with each stroke his balls would hit my clit.
Katie would lay beneath me, kissing me and rubbing my belly as it hung down.
Sometimes he'd cum inside me -- it wasn't like he could get me pregnant, after all -- and shoot rope after rope right into my cervix. And every time, the heat of his cum made me follow quickly after.
And then sometimes he'd pull out and aim between us. He'd splash his cum wildly, on my belly and across Katie, and she'd rub it onto both of us.
Rarely, he'd pull out of me at the last second and stick his full length right up into Katie. It always made her shriek -- she was wet and ready from watching, but he was still so big -- and he'd start cumming immediately.
She had an IUD, but that didn't stop them from pretending: "it's all going inside me," she'd say. "You make so much cum in those big balls and you saved it all for your sister."
"Just for you, baby," he'd respond. "I'm pumping you full. I want to knock you up just like Jill. I'm going to make your tummy so big, sis."
She'd groan and whimper, and I'd wish I could tip my head down to see Seth pushing his seed into his twin again and again, but my belly was too big. Their talking was usually enough, though.
"Stay inside me," Katie begged. "If you pull out the cum will drip out and I won't get knocked up. I need you to knock me up, Seth. I need your baby inside me."
Like I said, it happened rarely. But that was my favorite every time.
So I always enjoyed a nice fuck from Seth. But Jason, oh--
Most of the time Jason liked me on top. That meant he could put both of his hands on my stomach, and he always liked to comment that it felt a little bigger than the last time.
This also meant I could ride him slowly, sinking down onto him inch by inch. He still felt massive inside me, like a baseball bat splitting me open.
("Better get used to that," he joked once. "I think our babies heads are going to be a bit bigger than me." Honestly, I wasn't sure.)
"You feel so good," he'd say. "You take me so well."
"Jesus, if you told me growing up that my brother's cock is as thick as a Coke can, I don't even know what I would've done."
He laughed at that.
I'd grind against him until I came, and then he'd take over and thrust up into me until he followed shortly after.
But then sometimes, he'd lay behind me and cradle me, hold me close and caress my breasts and belly and whisper how beautiful I was into my ears.
We did this more and more as I continued to grow, since riding him got a lot harder with my belly so big.
We did it the night I went into labor, in fact. I sort of think he made my water break by shoving that thing inside me, but I'll never know for sure.
--
I went to the pharmacy a few weeks after I had the twins, and I got on birth control. Finally, right?
It was an easy choice: I wasn't going to stop having sex now, but I needed to at least graduate college before I even thought about getting knocked up again.
I kept fucking Seth, and Katie kept occasionally fucking Jason. But it happened less and less frequently individually, until it only happened when we got together for a foursome. Then we'd swap. But our brothers became our de facto partners.
--
Years passed. Jason and I moved far away from home, of course -- you can't exactly raise your kids together in a town where everyone knows you're siblings.
We kept in contact with Katie and Seth, visiting each other whenever schedules aligned.
One year, we arrived to a surprise: an IUD packaged in a neat little box.
Jason clearly didn't understand: "Katie, you're great, but I already always fuck you with a condom."
"I know, stupid. That's not the point."
He just stared: some things -- including our shared innocence and occasional stupidity -- never change.
"I got it removed for a reason," she patiently explained. "And I figured you two would want to watch the special moment."
So that's how we found ourselves living out that fateful college moment, but this time in reverse. They had us start first, had Jason work his way up inside me while I gasped and held his shoulders and Katie and Seth watched.
Katie, ever the bold one, muttered an uncharacteristically quiet request: "Talk to him? About... you know."
So I did: "Are you going to knock me up again, Jason? You did it by accident back in college, just stuck your cock inside me and put two babies in me. If you do it on purpose, I bet you can do better than that."
It was only when they were utterly and totally worked up, impulsively rocking against each other, that Seth slipped inside Katie. I knew his cock well, but I knew I'd never experience it like she did.
That was a feeling reserved only for his twin, the one person in the world made to fit him exactly.
I really believe it's the most special moment ever, having that psychic twin connection that makes you understand precisely what you both need as you get filled up over and over by the boy that was raised with you.
It only took a few strokes for Seth to groan and freeze, and Jason and I watched eagerly, knowing we were watching another pair of twins make a new life.
I'm not sure how we all knew it was happening in that moment, but we did. Seth pushed up as hard as he could and groaned, as it he were trying to thrust his way straight up into her womb. Given how long he was, he probably got close. And Katie shoved down just as hard. As Seth's balls pulsed and pulsed and slowed, we knew -- all of us -- that Katie had just been bred.
It was such an incredible sight that I didn't even realize that Jason was pumping his own cum inside me at that very moment until after.
A few weeks later, we got the joyful call from Katie. She was only pregnant with one, so she assured me that they'd be having another someday. A pair is best, she said with a laugh.

As for Jason and I, we were happy with our two. The twins -- Maddie and Nathan, because we couldn't bear to continue the alliteration thing -- grew up.
Nathan looked like me, with light brown hair that tended to flop over his big eyes. His penchant for soccer kept him strong and lean.
Our daughter took after Jason: blonde, wavy hair, and a naturally lithe frame. But he was tall, and Maddie was not: she was decidedly below average height, a born ballet dancer.
And yes, we decided to home school them.
If I do say so myself, we did a pretty good job. Like I said, our family had never been weird shut-ins or anything. The only issue Jason and I faced was our lack of options for experimentation.
But there was an easy solution to that, we knew. So on the twins' eighteenth birthday, we introduced a new course to their home schooling curriculum. Sex Ed 101, we called it.
They were unsure at first, just like we had been, so we followed the same steps Katie had until they were comfortable.
When they were ready, their first times were with Jason and I -- protected by condoms, of course.
Maddie struggled with Jason's cock, as I expected she would. We had him lay down and Maddie straddle him, so she could take him at her own pace.
I sat next to her, and she held my hands, gritting her teeth as she tried in vain to sink down onto her daddy's length. That first time, she only managed to get a few inches in her, but I was so proud that I licked her to three orgasms that night. And then the next time, she took almost the whole thing.
Nathan wasn't as thick as his dad, but he had an extra half inch or so to work with. He slid into me hard and quick, and I came on the second stroke as he hit me in just the right spot again and again. He had stamina, too, fucking me for almost a half hour before he stilled and I felt him pulse inside me and release spurt after spurt of hot cum. I knew he'd be perfect for his sister.
We changed the lesson plan for the final exam. After all, Katie had never intended for Jason and I to really fuck. But Maddie and Nathan were ready and wanting.
I knew Maddie was unprotected, but I wanted -- needed -- her to experience the beauty of that first unprotected moment, and she agreed wholeheartedly. I booked her the earliest appointment I could for a few weeks later, to get her on birth control.
And on that final night of lessons, Jason and I brought our twins into our bedroom and prepared them. We laid Nathan down on the bed, and I sucked him until his dick stood proudly upward and his breath came in heavy pants.
We sat next to him and helped Maddie straddle her brother.
Jason stroked Maddie's hair, telling her how proud he was of his little girl, as she sank down onto Nathan with a squeak. As soon as he was fully in her, they both froze in unison.
Like children, like parents.
I'll never forget that first moment when Jason was fully inside me for the first time and I understood at last what it meant to be a twin. And I knew now that neither of my kids would ever forget either.
Maddie looked over at me in awe. "Mommy, he fits inside me so good."
"I know," I said, and I did. I knew better than anyone. "You're twins. It's what you're supposed to do."
"Yeah," she whispered.
Nathan murmured his agreement too. "She's so tight, oh fuck."
I felt the bed shift, and Jason moved behind me. He pushed into me as Nathan began to thrust up into Maddie, and I felt like I was crumbling. From the inside out I fell apart, each and every nerve in my body going haywire and then numb, and my limbs turned weak. I tumbled forward, catching myself on Maddie's shoulders as she giggled.
"I guess daddy's cock is big for you too?" she said.
"Every time, sweetie. Every time."
Our hands on each other's shoulders, my daughter and I balanced each other as we got fucked deeply, fully. She made the cutest noises, little gasps each time Nathan bottomed out in her and disappointed sighs each time he withdrew.
"I'm getting close," Nathan gasped out. "I'm gonna--"
He dug his hands into Maddie's hips and pulled her down. Maddie had no intention of going anywhere, but I helped too: I pushed her shoulders, sinking her down, making sure her brother's cock was as far in as it could go. His whole body jerked as he came, and she let out a long cry.
They stayed like that for a while, panting wildly and trembling through the aftershocks of their orgasms, and then she leaned down to curl into him.
"I feel really warm and sticky," Maddie laughed. She squirmed a bit as she pulled off of Nathan and looked down to watch his cum stream out.
"That's neat," Nathan said. "It's crazy that it all fit inside you."
"No wonder it felt like you were blowing me up like a balloon!"
Nathan shrugged, seemingly almost embarrassed.
"Your brother will probably always cum a lot, just like I do," Jason explained. Maddie nodded.
And as if to prove his point, Jason thrust once more within me and came, but his thickness plugged all of his semen inside of me as he pulsed again and again. He stayed in me for a long moment, rubbing my back gently.
I had never felt so complete.
Finally he withdrew and slowly clambered back next to me on the bed.
Soon we were asleep together, the four of us spread eagled across the bed.
--
We didn't end up going to that appointment. It was already too late.
But I did have to take Maddie to the doctor soon anyway.
This time, I was the one sitting next to the examination chair, as my daughter watched the doctor press the ultrasound machine to her stomach.
And that's when we found out that twins really can run in families.
