I woke up from my unplanned nap feeling good. Very good, extremely good even. So good that I moaned loudly as I ended up unloading the contents of my balls into my sister's eager mouth. Still slightly groggy, I pulled the sheet up so I could see Elayne under it, resting between my legs with an appreciative smile on her lips.
"Hey there. Sorry, not sorry to wake you. I figured you probably wouldn't mind too much if I did it this way, and when I saw how hard your cock was I just couldn't control myself."
I dropped the sheet back down over her, laughing. "I can't think of a better way to wake up. Maybe you should be my new alarm clock."
Crawling up the bed, Elayne's head popped out next to mine a moment later. "You'd like that, wouldn't you?" She pecked my cheek with a kiss. "Of course, so would I... But now you're distracting me. I want to give you a reward as thanks for going along with my ask earlier, and for doing such an amazing job at it."
I blushed slightly. "Oh. Not a problem, I had a lot of fun doing it. Waking up with my cock in your mouth is definitely a nice reward, though."
"No, no, no," she replied, shaking her head vigorously. "That wasn't your reward, that was just some side fun. Your reward is way better than just a blowjob, you get to ask anything you want--anything at all--and I'll do it."
The last vestiges of my sleepiness vanished in an instant at her words. Anything?! My first thought was that surely she couldn't actually mean that. I'd be lying if I said my second thought wasn't that I could finally fuck my sister. Pushing that to the side, I wracked my brain for anything else that I could ask for, trying to come up with something that would be similar to what she'd asked of me. An idea slowly came to mind, something that I thought would be amazing for both of us, as well as help push us closer to the final goal we were clearly racing toward.
"I... I want you to hotdog me," I stammered. It took all of my courage to say the words, and even as I did, I worried I was going too far. Yes, we'd already pushed the boundaries lightyears beyond what was considered acceptable sibling interactions, but this... this was as close to actually fucking as you could get. And while I technically could have requested that, given the rules she'd laid out, a part of me knew that it still wasn't quite time for that yet.
For her part, rather than looking shocked or appalled, Elayne simply seemed confused. "Hotdogging? I'm... honestly not sure what that is. I'm not sure how I feel about that." She cocked her head to the side. "A little embarrassed, I guess, but also proud that you know about something sexual that I don't. So, what is it? And why are your cheeks so damn red? I'm not going to regret this reward, am I?"
I couldn't believe it. She didn't know? And now I had to explain? It was a struggle for me to think of anything that could possibly be more embarrassing than this.
"Um..." I cleared my throat. "It's where you put your pussy on my cock, and then grind on it. My cock is the hotdog and your pussy lips are the bun." My eyes were fixed on the ceiling overhead as I explained, but I snuck a look at my sister out of the corner of my eye to see her reaction.
"Holy fuck, bro. That's so damn hot." She was giving me that lust-filled look I'd become intimately familiar with. "Also, I guess I lied, technically. I did know about that, I've just never heard it called hotdogging, but I can totally see it now. Shit, you've got me excited, we're totally doing this."
I wanted to curl up and die in embarrassment, but at the same time, I couldn't stop the pounding of my heart. She'd said yes. We were actually doing to do this. I grabbed the sheet over us, preparing to pull it down so it wouldn't be in the way. I could already imagine her on top of me, her wet pussy sliding along--
Elayne's hand caught mine, jerking me out of my thoughts. "Not right now," she said with a laugh. "Something special like this should be done with careful preparation, and at the right time. Come to my room tonight after our parents are asleep, okay?"
"Oh." I was unable to hide my disappointment, resulting in another laugh from my sister.
"Trust me, it'll be worth waiting." She brushed her lips against mine in a faint kiss. "And now we should probably spend the rest of the day doing more normal things, so Mom and Dad don't start wondering what's going on with us."
Elayne slipped out from under the sheets, only deepening my dismay. But as much as I wanted to spend the rest of the day fooling around in bed with her, I knew she was right. We were already playing an incredibly dangerous game doing what we were while our parents were around, and all it would take would be a single slip-up for shit to hit the fan. As she left my room with a wink and a wave, I slowly crawled out of bed and got dressed before heading downstairs as well.
The afternoon passed in agonizingly slow torture. Every time I made eye contact with my sister I wanted nothing more than to tackle her to the ground and have my way with her. The worst part was that I could tell she knew exactly what I was thinking, as she bit her lip or even tweaked one of her nipples if she thought our parents wouldn't see. Eventually, I couldn't take it any longer and announced that I was going to go out to mow the lawn. It wasn't what I wanted to be doing, but it would get my dad off my back and give my dick a chance to calm down.
As soon as I stepped out into the backyard, I immediately realized that while the grass had gotten a bit longer since last week, it didn't really need to be cut. Even so, I went ahead and got the mower, determined to have some time away from the sexual temptress waiting back inside. Everything was going great, all things considered, until I was just finishing up the first third of the lawn when Elayne stepped outside wearing a blue bikini. In December. And looking hot as fuck.
Seeming to ignore me, she made her way over to one of the lawn chairs on the back patio and laid down on her back, her eyes closed. I struggled to wrap my head around how sunbathing in winter could possibly be "more normal things." Even if it was sunny out, and not terribly cold--especially in the sun--I knew she was only doing this specifically to torment me. And fuck if it wasn't working as my cock began to stiffen again in my pants.
She seemed content to just lie there as I finished mowing the lawn, doing my best not to constantly sneak peeks at her and failing miserably. Once I finished up, I was tempted to just head back inside and ignore her completely, but I couldn't resist my sister's magnetic pull on me.
"Aren't you cold?" I asked, dropping down to sit on the chair next to hers.
"Harsh, bro. You're supposed to tell me I'm smoking hot." Elayne didn't even open her eyes to look over at me, but she was smiling.
I laughed, my eyes glued to the fabric over her breasts. "I mean, you certainly are, but given how pointy your nipples look, I think you might be a bit underdressed."
She gasped in mock outrage, one of her arms shifting upward over her chest to cover herself. "Oh my gosh, are you perving on your sister?"
"Only because she wants me to." I put one of my hands on her arm, directly over one of her boobs. "I can think of a way to warm you up a bit, too."
"Oh?" She sucked her lower lip into her mouth briefly, before finally opening her eyes to look up into mine. "And what would that be?"
"Just a bit of a massage." I shifted my hand off her arm, down to her chest, and then slipped it under her bikini in one smooth motion, palming her tit. Her nipple was indeed rock hard.
"When did you become such a naughty brother?"
"Hmm, I wonder." I shifted my hand slightly, so I could rub my thumb over her nipple--earning a soft moan in response to my efforts.
"Well--"
The sound of the sliding door to the backyard opening interrupted whatever Elayne was about to say, and my hand jerked out of her bikini so fast I nearly pulled it off of her entirely. She quickly adjusted herself as I shifted away and did my best to look like I was only chatting with my sister.
"I feel like lemonade is usually what I'd bring out for sunbathing, but given the time of year, I went for some hot cocoa instead," our father called out as he stepped into view, a mug in each hand.
"Thanks, Dad, you're the best!" Elayne chirped, sitting up to take the mug he held out for her.
I nodded my thanks and took the other mug, appreciating the warmth it provided.
"Don't take the sun lightly," he told Elayne sternly. "Even if it's colder outside, you're still able to burn up."
Reaching down, she grabbed a tube of sunscreen I hadn't noticed. "Don't worry, I've got it covered, and Erik can help with the spots I can't reach, right, bro?"
I nearly sprayed the hot chocolate that was in my mouth all over. "Uh... yeah, I can help, I guess," I said once I finished choking it down.
He smiled. "I'm sure you've already heard this from your mother, but it's nice to see the two of you getting along. Anyways, I should get back to working on dinner."
We both sipped at our mugs until he was back inside. As soon as he was out of view, Elayne turned to me, her eyes twinkling.
"Well, what are you waiting for? Lotion me up."
I blinked. "What parts can't you reach? Your back?"
Elayne's eyes flicked down to her hands. "Can't reach anything while I'm keeping my hands warm, silly. Plus I believe you said something about a massage."
Not needing to be told twice, I downed half the contents of my mug--nearly scalding my mouth in the process--and grabbed the lotion from where she'd set it down. Squirting a generous helping of it on my hands, I began rubbing my sister's body all over as she giggled and sipped away at her drink. While it wasn't terribly erotic, especially compared to a lot of what we'd been up to, I loved the feeling of running my hands all over her body. Elayne seemed to be enjoying it as well, particularly when my hands slipped under the bikini.
All too soon I had her fully covered, but I didn't let that stop me from the massage portion. Sliding one hand inside her bottoms, I pushed two fingers into her drenched pussy while my other hand went to play with her nipples. Elayne was forced to set her mug down so she could cover her mouth to try and muffle her gasps and moans. As much as I wanted to give her another orgasm, doing this outside was actually far more risky than inside the house. Noise wasn't the largest danger here, since it would be possible for neighbors to catch a glimpse of what we were doing. Reluctantly, I slipped my hands out from under her bikini after a bit longer, earning a somewhat annoyed, but understanding look from my sister.
"God, I wish you'd made me cum, but good thinking that there's no way Mom and Dad wouldn't notice how soaked my bottoms would be."
My mouth fell open. I hadn't even considered that. "Oh... yeah. I'd love to finish, but prolly best we save that for later."
"Dinner is going to be ready soon anyway, I should go get changed. Thanks for the massage, bro." She gave me a wink and almost leaned over to kiss me before seeming to think better of it. "See you in a bit."
Quickly storing the lawnmower in the garage, I made my way inside where I found my parents putting the finishing touches on dinner. I went to set the table, earning a thankful smile from both of them, and it wasn't much longer until the four of us were seated around the table chowing down on roast chicken and mashed potatoes. I hardly paid attention to what our parents were saying, thanks to Elayne's leg repeatedly shifting over to bump into mine combined with the knowledge of what we were going to be doing later.
Once dinner was over, we ended up playing a game of Scrabble as a family, although I could hardly focus on the game and was too self-conscious to play all the inappropriate words that came to mind. At one point I even had "incest," which felt like a horribly accurate coincidence. When the game wrapped up with our mom as the winner--as she always was--Elayne told our parents that we'd handle the cleanup so they could head to bed. As soon as they disappeared up the stairs, she told me to be in her room in thirty minutes and vanished upstairs as well.
If I hadn't known what she was preparing for, I might have gotten annoyed at being left to clean everything up on my own. As it was, by the time I finished I instead found myself wishing it had taken longer since there was still far too much time to burn until Elayne would be ready. Making my way up to my room, I noticed that she'd closed my door to the bathroom, and pressing my ear to it I wasn't able to hear anything from the other side. Not knowing what else to do, I dropped onto my bed to wait, lightly stroking my cock as I imagined what Elayne might be doing.
Right around the time I felt like the thirty minutes had passed, the bathroom lights flickered on and off three times, which I interpreted as her signal that she was finally ready. Eagerly jumping to my feet, I removed all of my clothes except for my boxers and hurried into the bathroom before throwing open her door. When I saw what my sister was wearing, I came to an abrupt halt, my jaw nearly hitting the floor.
She was dressed in a red one-piece, except it was very clearly lingerie as it did almost nothing to hide her body with how sheer it was. The detailed embroidery of the top half left her nipples clearly in view, and the bottom was so short that it ended at her waist, doing nothing to conceal the matching red thong that was the only other thing she had on. In short, she looked so ridiculously fuckable that my dick was instantly rock-hard and throbbing.
"I'm going to assume from your stunned silence that you like the babydoll?"
I could only nod my head.
"Come join me on the bed," she whispered, beckoning with a single finger as she sat down.
I crossed the room in what had to be record time, dropping down to sit next to her. Words continued to elude me as I could only stare, mesmerized at how she somehow looked even hotter this way than when she was completely naked.
Elayne giggled. "Well, it certainly seems worth the purchase. I was hoping you'd enjoy it, but this is a bit beyond even my expectations. Shifting, she moved one of her legs over me so that she was sitting in my lap, facing me. We were so close that I could feel her breasts pressing into my chest as she kissed me deeply. "What do you say we start this reward of yours, hmm?" she asked as she broke away.
"Yes... please," I finally managed to gasp, my mouth feeling incredibly dry.
Placing her hand on my chest, she gently pushed me backward so that I was lying down. "Shift up, so we don't have to worry about falling off the bed."
Doing as she instructed, my sister adjusted with me so that her crotch remained firmly pressed against mine. Once we were fully centered on the bed, her hand drifted over to one of my nipples which she slowly began to circle with one of her fingers.
"So, brother dearest, earlier today you said you wanted your sister to grind her wet little pussy along your hard dick. Is that still the case?"
Her eyes were locked onto mine, and the tone of her voice was so ridiculously seductive I could hardly stand it. Part of me was even more tempted to change my mind, to ask her to just fuck me already, but instead I nodded once again.
"Such a naughty boy, asking his sister to do something so filthy. But I suppose if that's what you truly want..." Elayne shifted her waist slightly and from both the heat and slight wetness I could immediately tell that her thong-covered pussy was resting on my cock. "I suppose we'll need to take a few things off, first."
It was hard not to be disappointed as she raised herself off of me, breaking our contact, but knowing what was about to happen made it well worth it. I awkwardly did my best to slip my boxers off, my eyes fixed on Elayne's pussy as it slowly came into view from behind the thong. Once she had it completely off, she helped with my boxers before settling back down onto me. Both of us moaned as her pussy made its first contact with my cock.
"Fuck," my sister gasped, trembling slightly above me. "Fuck."
I agreed.
"I can already tell this is going to be hard."
"Not as hard as I am."
Elayne giggled but stayed motionless above me. "I know I made you wait as I put this on, but I think I'm going to take the babydoll off."
I frowned. "Why? Don't get me wrong, I love you naked, but you look seriously fucking hot in that, sis."
She smiled, her eyes glowing. "Thanks. I'd leave it on, but right now all I can think of is how badly I want your cum all over my body at the end of this, and I'd prefer to not have to clean it out of this."
"Oh." The mental image alone nearly ruined me. "Well in that case..."
With a laugh, Elayne smoothly pulled it over her head, discarding the flimsy fabric on the bed next to us. "Plus, this way you have easy access to the boobs you're so obsessed with."
My hands were already moving, each one cupping a breast so that my thumbs were positioned over her nipples. Giving them a squeeze and a rub, I earned a moan from her lips. And then my sister began to shift.
It was only the smallest movement at first, less than an inch, but it sent electricity flowing through my body. I could feel her wetness coating me as her lips slid along my shaft. This was already everything I'd hoped for and more, and I knew that neither of us was going to last long with how crazy this was. Reaching the base of my cook, Elayne took a deep breath, closed her eyes, and then began working her way back up. Once she reached the tip, her eyes opened and they were all but dripping with lust as she leaned down to whisper in my ear.
"You know, bro, right now, all you'd have to do is thrust a bit and you'd be buried deep inside your sister's pussy. One little push and you're in."
My cock twitched, enough that I felt it catch briefly on her opening and I realized just how right she was. I couldn't tell if she was asking for me to do what she was saying, or just pointing out how hot it was, and before I could make up my mind she'd already adjusted slightly and began sliding back down my dick.
"Is that what you want?" she asked, still making eye contact. "Does my twin brother want to fuck his sister?"
"Yes."
"Say it."
"I want to fuck you."
"Say it hotter."
"Yes, I want to fuck my twin sister's wet pussy!"
Elayne moaned, arching her back in a way that let her press down harder into me. With the extra friction, she began to move even faster, now no longer slowly slipping up and down my length, but instead actively grinding my cock. Enough of her natural lubrication had spread over my shaft by this point that it was incredibly smooth and felt far better than any masturbation I'd ever done on my own.
"Gonna fucking cum," she hissed, biting her lip. "Gonna cum so hard from grinding my clit on my brother's dick."
I shifted my grip to more easily play with her nipples, and immediately felt her body rock as several tremors ran through her.
"Let me know when you're close. I want it on me, not your stomach."
I nodded, while doing my best to hold out--wanting to enjoy the experience of her pussy getting me off for as long as I possibly could. Unfortunately, my dick was already being pushed to its limit, and it wasn't much longer until I knew there was no way I could last any longer. "Gonna cum," I gasped.
Immediately, Elayne was up and off me, shifting into a kneeling position. Wanting to give her what she wanted, I stood up on the bed in front of her, my hand rapidly jerking myself off. It only took two full strokes before I saw stars as my orgasm arrived, nearly buckling my legs with its intensity.
It should not have given me as much satisfaction as it did to paint my sister's chest with shot after shot of my cum, but god did it feel incredible while looking so fucking hot. Elayne opened her mouth wide after the third blast, and I decided to indulge her, lifting my cock up slightly to send a stream of cum into it. Or at least, that had been the plan. Instead, it splattered all over her face, only a tiny fraction of it actually landing where I'd intended.
She didn't seem to mind in the least, a low purr of approval coming from her throat as her tongue slid around the sides of her mouth to lick up as much of the creamy substance as she could get. With my load spent, I collapsed back onto the bed in a daze, trying to process everything that had just happened. It had been everything I hoped for and so much more.
Shortly after, my sister flopped down at my side, lightly cuddling into my side. "Bet you're gonna have dreams of me after all this."
I laughed. "I already have, the night after all of this began when I saw you playing with yourself in the bathroom."
Elayne shot up into a seated position instantly, her eyes gleaming. "Wait, what? Really? What was it about?"
The image flashed into my head, and even though it was no longer as insane as it had been back then, I still felt my cheeks heating up. "You were sitting on the dinner table, spreading your pussy and you asked me to have you for dinner."
Before I realized what had happened, my sister grabbed my hand and tugged me to my feet. "Right. We're re-enacting your dream."
I blinked. "What, right now?"
"Yup."
