Chapter 2: My sexy Sis
Wendy, can I cum in your mouth again, please?"
"Jesus, James. Again?"
I'd become accustomed to swallowing my brother's loads, but this was getting tiresome (or so I told James, anyway). I'd been doing it nearly every day for weeks, sometimes twice a day. If I relented to his request now, it would be the third time today.
"I don't know what's going on, sis. I've just been so horny lately."
James and I were 21-year-old twins, currently being kept hidden in a small, one-room, underground bunker that belonged to a Dutch family. James and I were Irish. Even before the war began, the enemy had been rounding up and executing all the Irish. My brother and I were lucky to have found a member of the resistance who led us here.
The toilet didn't work in the bunker, and even so, it was literally in the same room as the rest of the space. I'm glad it didn't work. Besides the non-functioning toilet, there was a small kitchenette and cabinets holding canned food, mostly beans and greens. There were two twin mattresses, but we kept them so close, in order to allow more space. They almost served as a double.
Without a working toilet, the family permitted us to pop open the hatch, and use a small area outside nearby. The father of the family would come by once every few days to scoop up the evidence. There was also a light in the bunker, and the family would trigger it when it was unsafe to go outside.
There were other rules, too. We were only allowed out during quiet, daylight hours. Never at night, due to the risk of getting lost, as the bunker was very well hidden, deep in the woods. We used safe, tree leaves to wipe, as paper would increase the risk of exposing our presence. Enemy soldiers did patrol the area on occassion.
We were in the bunker just two weeks when James stated he couldn't take it anymore, and complained that he needed sexual release. Because we weren't allowed out at night (and he dared not go out in the middle of the day to do it), I turned my back and he did his business right there in the bunker. This continued for a few days, until the odor became overwhelming. I mentioned it to James and he griped back, "What am I supposed to do about it? We don't have disposable tissues, and I have to use this rag."
Always the sarcastic one, I held my nose and said, "I'd rather swallow it, if I never have to smell it again. That's fucking gross, bro."
"Well, it is a solution!" my brother barked back at me. "I'm sorry, but you don't know how it is being a young man. Most guys jerk off way more than I do."
I had a boyfriend once and knew that my brother wasn't exaggerating.
"Well, we've got to figure something out," I said.
"Were you serious?"
"About what?"
"Swallowing. It would solve the problem."
"Fuck, man, what is wrong with you?"
My brother could be just as sarcastic as me and retorted, "Oh, I don't know. Being trapped in a fucking cubicle with my sister, while going through puberty?"
I rolled my eyes."You're an adult."
"Look, Wendy. I appreciate you not being weird about me needing to jack off once a day, but I don't mean it to cause this problem. You're right, it does stink in here. Still, I can't help it. We'll just have to get used to it."
Now I really rolled my eyes. "Fine!" I screamed. "I'll open my mouth right when you're about to cum, but I'm not going to help in any other fucking way. That's taking things way too far."
Honestly, I don't know what compelled me to agree to this. The stench wasn't that unbearable... but I also think I was exhausted. Tired of running, hiding, not getting to actually live a real fucking life. If anything, swallowing a load of cum would break the monotony, and I'd always enjoyed sucking it out of my boyfriend. Still, I never would have wished to do with my brother, before this.
"In your mouth? Really?" His tone was flat, unbelieving.
"I'm not having that splooge land anywhere else in this fucking room," I snapped. "When you're about to cum, put it directly in my mouth. You better time it fucking perfectly, asshole. I'll close my mouth around your shaft to keep from spitting any out, but don't get any ideas. Got it?"
My brother nodded. He knew better than to argue against me. He might actually change my mind.
"Well?" I screamed. "Get fucking on with it."
And a few minutes later, I was guzzling down the first of many loads of my brother's surprisingly tasty sperm. Maybe it was our clean diet, but secretly I really did love the taste. I'd never let him know that, though. He shot huge loads regularly, sometimes a dozen swallows or more.
Now, here he was, asking for a third time, and all I could think to do was feign revulsion. At some point, I had to admit that I was fine guzzling my brother's sperm multiple times a day. Perhaps I even liked it. A thought occurred to me, and I asked him a question.
"Maybe, James... Maybe you need to get more satisfaction from it? Or maybe you're getting too much? Who knows?"
"What do you mean?"
"I don't know - but if you promise this will be the last time today - I will open my mouth, and you can... well.. I dunno.. pump your cock in it.. .until you cum, anyway."
"What, really?"
"Maybe you'll get whatever you need out of this, and you can stop asking me to do this all the time. But I'm only letting you use my mouth to TRY it. I'm not going to help, or act like some slut girlfriend of yours. You understand?"
"Uh, I think so. You're just going to let me fuck your mouth?"
I almost shivered, but I wasn't sure if it was from excitement, or the shock of hearing my brother say those words. It wasn't revulsion.
"Yes. Fuck my mouth. Use it. But, please be considerate," I said, sternly.
"Of course. Well, now then?"
"I don't see why not."
I was always impressed by my brother's cock. Having to open even wider to take it all in was quite a feat, but I managed. Moments later, he was sliding it back and forth into me. It felt warm, and feeling it stiffen harder under my lips had me getting damp down below. I hoped he wouldn't take too long.
On a couple occasions, after I swallowed my brother's cum and he went to sleep, I discretely masturbated, thinking about the images in my mind, the taste of his seed. I suspected, after this experience, it would happen tonight. Already, I felt his veins thicken, the climbing. He was getting closer, and now I heard moans. I kept my head still.
He pressed his hands firmly behind my head, but didn't drive his cock in too deep. Instead, he paused, squeezing his muscles and cheeks. I felt it about to explode, and I prepared myself, breathing in.
The first rush hit the back of my throat with heavy force, and I swallowed fast. It was bittersweet and thick, and I bore down harder, sucking deeper as he unloaded more into me. Without thinking, I found myself pressing on my clit with my left hand while I kept swallowing. I was soaking wet, climbing higher.
James cried out one last time, as another rope of sperm hit the back of my throat again. I tongued his shaft as I pulled off, ensuring I licked and swallowed every drop of evidence.
"Thank you," he said.
It took a moment, but I responded, "You're welcome. Any time."
"Anytime? You mean it?" he cried excitedly.
I started to laugh, but stopped. "Well, no. I was just joking..."
"Oh, I uh... I was really hoping you would let me fuck you."
"James!" I exclaimed.
"Please. You are so hot. You could just do it the same way. Like I just used your mouth. You don't have to do much, I swear."
"You can't fuck me! Or cum in me!" I cried.
"Your mouth, I can. I wouldn't come in your pussy. Never! I just feel it... it's been so long for me..."
"James, I am not lawn and garden equipment that you share among neighbors. You don't just 'borrow' a pussy."
"Wouldn't you admit these are unique circumstances?"
As my brother argued, his cock hung low in front of me. I was still half naked and yet, not at all bothered by it. If he weren't related, I'd be begging for that cock. I eyed it for a moment. "What exactly would I have to do?" I asked.
"I dunno. Just bend over? It won't take me long."
"Bend over? And honestly, how long do you think it would take?"
"A minute or two, maybe. I mean, come on sis. Your pussy must be amazing."
I blushed and finally relented. "Okay, next time then. But I'll only promise one, bec-"
I didn't finish what I was saying, because my brother flipped me around, grabbed me by the hips and somehow shoved his once-again, rock-hard cock deep into my pussy. I came almost immediately, it touched every nerve. In seconds he was pounding me hard, relentlessly, using me like a piece of meat... and I loved every second of it.
"I'm gonna cum so much in your mouth, sis, you know that? You're gonna struggle to get it all down!"
"But you just came," I protested, succumbing to yet another orgasm as his glorious cock assaulted me.
"But this is so hot, and I know I'm gonna bust the biggest nut ever."
"You know it's hard for me to swallow it all, when you cum that much!" I cried. His dirty mouth was getting me so horny.
"You have to swallow it all, sis. Otherwise, maybe I should use your pussy."
"No!" I screamed. "I'll swallow it. I'll swallow every drop. Hold my head down if you have to. Make me do it."
Just as I exploded into another climax, James whipped me around and shoved his glistening cock deep down my mouth. I instantly began fingering myself hard and fast, as he used every inch of my open mouth.
"You ready?" he screamed.
"MMMmmmph," I cried, nodding. I wanted it so badly.
And as promised, James delivered the biggest load I ever experienced. With the tip of his cock on my lips, his thick juices filled my mouth entirely, and I swallowed faster than ever, trying to keep up with his after shots.
"You are such a slut!" he yelled, finally pushing his cock in deeper.
I came as the words rang true, gulping down more still. Finally, I pulled off, breathing hard, looking my brother in the eye. He was smirking. "Fine," I said. "I'll be your slut, but on one condition."
"What's that?"
"You have to use me like this every day, until we're free. If we're going to be stuck here, I need to have some fucking fun."
"And being a slut is fun to you?" asked James.
This time I smiled back. "Being yours does."
Chapter 3: Cumming in Covid
Fucking Covid right! I'm thankful to have made it through so far without catching it but the lockdown changed things, (yes for the better), that otherwise may never have occurred.
I'm Marcus, 19 and was home from college at the same time as my older sister, 21 year old Lisa, when the lockdown hit. We were pretty lucky, our parents had jobs they could do from home but we were forbidden from going out other than for essentials like grocery shopping. While our parents worked, Lisa and I had nothing to do but watch tv, we had all watched our way through pretty much every series that streaming had to offer and would take turns picking a movie. During the week was fine, we were allowed to have our laptops in our rooms and could play games after studying but our Mom was kind of anti computer technology and we were expected to socialize with them, albeit just sitting watching movies with them most nights.
As the weeks went on my sexual frustration began to climb too, usually with their work and school I had a good few hours of alone time where I could jerk off in peace, our walls were all really thin and the way our bedrooms were, there was no way I could stroke one with everyone home. Our parents were under the impression the lounge couldn't be heard from their bedroom of course so Lisa and I were quite often subjected to sounds of them having sex, normally an 'eww, gross' from both of us but when you're stuck at home, away from your sex crazy girlfriend, the sounds of anyone having fun was a turn on.
I knew I'd start going crazy without release though, I found that one corner in the house where I could jerk off without worry of being heard since I couldn't stay quiet when I came, thankfully a small bathroom and eventually worked out a window where I could get off and not be spotted or heard. I made it part of a daily routine, parents went to bed early to have sex most nights, Lisa would go shower when they were done and that gave me my window. That went well for a while until Mom threw a wrench in my plans and asked Lisa to shower in the mornings to help with the hot water balance but I made it work.
"Why the sad face Marcus, you're usually so chipper in the morning?" said Mom as we had breakfast.
"Oh, email from Jen this morning, she's decided this distance thing isn't working out and we've to go our separate ways," I replied.
"What? That bitch, dumped you over email? Almost as bad as my ex, dumped me by text last week," said Lisa.
"This stuff is hard for everyone, you just have to stay positive kids," said Mom.
"Easy for you to say, you get to go out shopping once a week," said Lisa.
"Well they talked about easing the restrictions in another month, you'll be fine," said Dad.
That night we were all sitting watching a movie, Mom and Dad made their usual excuses and went to bed, 10 minutes later we could hear Mom moaning, Lisa and I just pretended not to hear it as usual. The movie we were watching had a pretty raunchy sex scene in it though and I held out for as long as I could but I needed my release.
"Well, I'm going to bed, another day of boredom done with," said Lisa.
No sooner had she left the room I made my way to the corner bathroom, closed the door behind me and leaned back on the seat as I stroked my cock, gathering tissues for my impending climax. I froze though, I could hear footsteps and before I could react, Lisa came through the door, turned on the light as she kicked off her sweatpants and already had a few fingers in her pussy before she realized she wasn't alone. She froze when her eyes got used to the light and she spotted me sitting there, cock in hand.
"What the, what the fuck are you doing here!" she said in a loud whisper.
"What does it look like, only place I can get off in peace," I replied quietly.
Neither of us covered up, Lisa just looked at my cock.
"Move your hand away," she said, looking into my eyes.
I did as she asked and expecting her to just look at my cock as she masturbated, I got the shock of my life when she instead turned away from me and sat down to take me inside her. I gasped in shock and pleasure, she took my hand and put it up her shirt and onto her breast and began to ride me. I had already been close from jerking off, her bursting into the room took me away from the brink but being inside a warm, tight pussy for the first time in forever I couldn't hold back, I pushed up into her as I came, holding on to her waist as I exploded, emptying my full balls into her. Lisa furiously rubbed her clit and I felt her cum as the last few spurts from my cock filled her.
"Don't tell anyone, this is our secret," she said then got up and pulled on her pj bottoms and was gone.
"What the fuck!" I said to myself then cleaned up.
Next morning, Lisa didn't say anything different to me, I had spent a good few hours laying awake, going over it all in my head. I'd cum in my own sister, what if I got her pregnant? How would our parents react to that? I didn't get my answers until later.
"They're finally allowing a second person shopping, I'll actually get help this weekend. Your Dad has been called into work too, they finally realized he's important," said Mom as she drank her coffee.
"So who's helping you this weekend?" said Lisa.
"Your Dad, you're both still considered high risk because of your asthma."
"Mom, neither of us have had that since we were 10!"
"Well, there's a history, you have to stay home."
"This is bullshit."
Lisa stormed off, I just finished off my cereal.
"You're quiet this morning," Mom said to me.
"Just a little trouble sleeping is all," I replied.
"Well, I'm sure a nap later would be good, I'm going for a bath."
Once Mom was in her bath, humming away to her headphones music, Lisa came to see me in the lounge. She sat facing me on the couch and had me put my book down.
"So, last night. I have been stupid horny all week, I swear as soon as I breath different Mom can hear it and she's in my room 'are you okay?' before I can get off. That bathroom is like the only place I can cum in peace," she said with a smile.
"I know."
"Well, I couldn't help myself with you there, are you mad at me for taking advantage of you?"
"Mad, not the word I'd use, spent all night worrying, what if I got you pregnant, Mom and Dad would kill me."
"Is that all you were concerned with?"
"Well what else would there be?"
"Well, that I'm your sister and we had sex."
"Would hardly call that sex, you sat on my dick long enough to cum."
"But you're not grossed out or anything?"
"Not really, I'm stressed about knocking you up!"
"I'm on the birth control shot silly, I made sure to get it right before we went on lockdown too."
"You might have led with that, I've been worrying all night."
"I'm sorry. It really didn't bother you?"
"You should see my porn collection, I read erotica too, there's not much that would faze me sis."
"So, um, would you want to do it again, maybe last longer next time?" she said with a smile.
"In fairness, I was really close when you barged in, if you'd stuck around for another 5 minutes you could have had me again."
"Well then, same time tonight? Maybe when Mom and Dad are fucking?"
"I'll be hard and waiting."
The sexual tension was almost unbearable as we watched the movie that night with Mom and Dad, Lisa had changed into her PJ's as usual but had elected to wear a pretty tight fitting t-shirt and her nipples were hard the whole time. I had to wear my loose sweatpants to hide the fact I was semi hard the whole time so when our parents finally went to bed I was relieved. As soon as we heard Mom start to moan we were both on our feet and racing to the bathroom.
"I am fucking dripping already," said Lisa as she pulled at my sweatpants.
"Good because I'm already throbbing, bend over the vanity," I said as I stepped out of my boxers.
Lisa pulled her t-shirt over her head and I got to view her pert breasts for the first time, reflected in the mirror. I pushed into her from behind and played with her nipples as I started out slow, coating my cock in her juices and enjoying the view of her ass as fucked her. At her insistence I increased my pace and held on to her waist to thrust harder, she started to cum after a few minutes, shuddering as I kept sliding in and out of her. When she climaxed the second time I couldn't hold back and pushed as deep as I could and erupted, filling her with my seed for the second time that week. I stayed inside her as I caught my breath, my cock refusing to go soft.
"Holy fuck that was good, are you still hard?" said Lisa as she caught her breath too.
"Yea, when I'm super turned on I usually stay hard for ages."
"Nice to know, we should get back though, I'm usually headed to bed by now."
"You're going to leave me this way?" I said, finally pulling out.
"You'll get us caught, rub one out or something."
"It's fine, if I leave it he'll subside," I said, grinning.
"Listen, don't get cocky or get all weird on me okay, consider this a special treat since we're locked down and I'm so frustrated. If you're nice about it and play along, we'll have fun but piss me off and I'll go back to masturbating," she said then kissed me on the cheek.
"Sorry, I was just trying to be funny."
"It's fine, talk tomorrow."
Lisa left me while I cleaned myself up, I slept pretty well that night too and did my best to act normal around her. After dinner we watched the news and sat open mouthed at their announcement.
"Another 4 months of modified lockdown? What the fuck does that mean, do they not know how much they're messing with people's fucking lives here?" ranted Lisa, she was really mad.
"Lisa, language please!" said Mom.
"I'm sorry Mom but I can't take this, I love you all but I need to get out, need to be around different people. Expecting us to just accept it and stay home isn't fair."
Lisa stormed off leaving a stunned Mom, grinning Dad and me not knowing where to look.
"Are you going to say anything?" said Mom to Dad.
"She's right honey, it's okay for us but keeping them home all the time is harsh."
"Tell that to the Lawsons, their daughter, only 23, caught covid and she passed away."
"Mom, Darla Lawson smoked meth and who knows what else, pretty sure covid just got to her before the drugs did," I replied.
"They told us she quit that a while ago," said Mom.
"Nope, my friend John used to date her and tried to get her into rehab but she didn't care, he said she was still smoking that stuff a week before she got sick."
"Well, with both of your medical histories I'd rather be safe."
"Fine but we're out of stuff to watch, should maybe let us on our computers more, I mean, we're both adults."
"My house, my rules, I'm sorry. Maybe you could give me a list of movies I can get for you?"
"Bored of movies Mom..." I said then walked away too.
A few hours later my Dad came to my room, he had my laptop in his hand.
"So I spoke to your Mom, she's agreed to give you both more computer time. Just don't be downloading porn or anything okay?" he said.
"Awesome, thanks Dad. I don't suppose it comes with our phones for more than two hours a day too?"
"One win at a time son, you know how she is."
That night, as soon as our parents went to bed, Lisa pulled me by the hand to our corner bathroom. She pulled her sweatpants and panties down and bent over the vanity but I wasn't expecting sex again so soon and wasn't hard.
"What, you get bored of my pussy already, why aren't you hard?" she said, noticing I wasn't ready.
"I wasn't expecting you again so soon," I replied.
Lisa gave a frustrated sigh then pulled my shorts and boxers down and started sucking my cock, it didn't take her long to get me hard.
"Good and hard please, I've been frustrated all fucking day," she said, standing up again.
I got behind her and eased my cock inside her, gave a few slow thrusts to coat my cock in her juices then built up a pretty hard pace that she'd requested. I shifted my stance a little to give more strength to my thrust, Lisa responded with a 'oh fuck yes, right there' so I kept it up until she gasped 'cummming...' then almost went limp as I continued thrusting. When I kept my furious pace, Lisa reached back and tapped my hip.
"T.. ti.. time out," she said, breathlessly.
"Sorry, you okay?" I replied.
"Y.. yes, I just need a break, you're thumping my button really well, feels amazing but I just came so hard, I need a minute."
"Okay."
"Are you close?"
"Kinda but I'll take a few to cum this way."
"Okay, you can go again, deeper but not as fast."
I did as she asked, it took her cumming again to set me off, I pushed in as deep as I erupted, shuddering as I sprayed my seed into her. I stayed inside her until my cock started to soften then slowly pulled out, she pulled her panties and sweatpants back on then left quietly.
For the next few nights things went the same, I'd spend my days just looking forward to being inside her again, I hated to admit it but lust had me wanting to do anything to please her, something Mom picked up on when Lisa asked me to get her a drink as we watched a movie one night.
"You threaten him or something, usually he'd tell you to get it yourself if you asked for a drink," said Mom.
"Well, since we're stuck in this house together we came to an agreement to be nicer to each other," said Lisa without a pause.
'And by nicer we mean fucking each others brains out' I thought to myself.
Later that night after we'd just had sex, Lisa paused before she left for her bed.
"Hey, you have to be more careful about changing so much around Mom and Dad," she said.
I was still coming down from an explosive orgasm, couldn't think of anything to say so I just put my hand on her cheek and kissed her softly on the lips.
"Wh.. what the fuck Marcus," she gasped, pulling away from me.
"What?"
"We're fucking, I'm a wet pussy to spray your cum into, that's it. We're not lovers, we're not going to run away and spend our days gazing into each other's eyes for fuck's sake. Why do you think I always have you take me from behind?"
"I couldn't help it. You can't expect to give me this and have me just cum in you and not want to please you in return. I love this but I care about you too."
Lisa just looked at me for a few seconds.
"I love you, but you're my brother, Marcus, don't go falling in love with me okay, this is just sex to stop us both going insane thanks to Mom. I won't be here tomorrow night, I need time to think."
I spent the next day with my head in a book, I was terrified I'd fucked things up, that I wouldn't get to have her again. That night though, when our parents went to bed, Lisa pulled me to the bathroom without saying anything. Once the door was closed behind us she pulled my face to hers for a kiss that seemed to last forever.
"I'm sorry about last night, I was kidding myself that I wasn't enjoying the intimacy between us even though it's always been from behind. If you want, we can try other ways, we can be secret lovers until all this is over," she said after finally breaking the kiss.
"I would like that," I replied.
"Good, now I hope that is your boner I feel poking me, want to try taking me with my ass on the vanity?"
"Sure!"
Pushing my cock into Lisa's pussy felt different when I could see her face, see her pleasure in her eyes, the position didn't allow me the force I could give her from behind but we lasted longer and our orgasms felt more intense. She kissed me softly on the lips then held me as my cock softened.
"So what happened to super turned on, can stay hard twice?" she said, grinning.
"Oh it wouldn't take much to get me going again but that was amazing," I replied.
"How about we try anal tomorrow, I haven't had it in so long, I'll bring the lube,"
"I've never had that before."
"Well, jerk off in the shower tomorrow if you can so you last longer in me, I will try and wear my plug but I'll be tight."
"Can't wait." I said, grinning.
"I'd best go, goodnight."
Lisa gave me one more kiss then dressed, quietly slipped out of the room. I never could get off in the shower but I managed to jerk off while Mom was making dinner, she gave me a look when I sat down at the table. Time seemed to be going slower that day too but parents finally went to bed and Lisa and I practically sprinted to the bathroom.
"So, I want you to eat me until I cum so that I'm a bit more relaxed," she said once she'd stripped naked.
"Oh good, I love eating pussy," I replied.
Lisa sat on the vanity and opened her legs, I was already hard but I kissed her first then kissed my way down her body, sucking each nipple to hardness before finally kneeling before her, her beautiful shaved pussy in my face. I started slow, licking and tasting her juices, exploring every inch of her labia then when her breathing got heavier and her clit engorged, I rasped it with my tongue until she shuddered, flooding my tongue with her cream. She pulled me up to kiss her when she got too sensitive, kissed me with a passion she'd not given me before and I loved it.
"Th... that was awesome, you can definitely do that again. Ready to fuck my ass?"
"Hell yea I am."
"Lube's in my pocket."
I watched as Lisa pulled the plug from her ass then she took the lube from me, coated my cock and pushed a few fingers coated in lube into her ass. She got into position and took my cock in her hand, guiding me to her asshole.
"Take it slow until I tell you okay," she said.
She was right about being tight, it felt amazing, I slowly pushed inside her, thrusting slowly until she had all of me, my balls resting against her soaked pussy.
"Ohhh, that feels fucking good, okay baby, nice and slow."
It took a while but I built up my pace, thankful I'd managed to cum already or I'd have exploded in seconds but I lasted through 3 of her orgasms, she was furiously rubbing her clit as I pounded her and I could only groan when I finally came. I held her tight as we caught our breaths.
"I think that will settle me for a good few months, you're bigger than my ex so I couldn't take this every week," she said in between kisses.
"Well I enjoyed it for my first time," I replied.
"Goodnight my love."
Next day at dinner Mom had some good news.
"So, your father and I will be going back to the office, you will both be allowed to be on your phones and computers more and we still expect you to be doing the laundry but you should be allowed to leave the house soon too," she said.
"Oh that's awesome," said Lisa.
"I'm installing cameras outside too so no sneaking out," said Dad.
That night as I fondled Lisa's breasts from behind, my cock still twitching from filling her with my cum, she leaned back against me.
"I can't wait to take you on a bed, I'm going to ride you, sit on your face, 69 you and make you fuck me hard while I'm on all fours," she said, almost purring from her orgasms.
"It'll sure be nice not to have to be quiet too," I replied.
"Oh fuck yes, so many times I've wanted to scream in pleasure but had to suppress it. I'll tell you what, Monday is sheet day, let's spend all day fucking. Soon as they're both gone I'll come to you, wake you with a nice wet pussy on your lips."
"Can we tape it so we can watch ourselves later?"
"Fine but I'll seriously cut your balls off if you show anyone."
"I wouldn't."
That Monday was like Christmas to me, Mom and Dad left for work and after she confirmed the house was empty, Lisa came bounding into my room with no clothes on. She helped me set up my camera then after making out we got into 69 position, her on top as she sucked my cock and her pussy perfectly positioned for me to eat her. I got a little mad at the time but found out why after it, right as I was cumming, while she was spraying her cum over my mouth and chin, she stopped sucking me. I spurted once then she put her mouth back on my cock as I finished my climax. When she got off me my heart dropped and I wanted nothing more than for the ground to open up. Mom was there and she was standing there with mouth wide open
"Um, Hi," said Lisa.
"Wh... wha... What the fuck Lisa?" said Mom finally, her voice wavering. Mom rarely cussed.
"You're not at work,"
"They, they weren't ready.. WHAT THE FUCK ARE YOU DOING?" Mom seemed to snap out of her shock.
"You lock us up, away from our lives, away from distractions, what did you think would happen?"
"Not THIS! She's your sister Marcus, did you not think of that?"
"Only the first time, it's just sex, we're not in love or anything," I replied, trying to match Lisa's defiance.
"You... You shouldn't be doing this, you can both tell your Father, you better be dressed and downstairs when I get back, I'm going out to get wine.."
Mom left, her tires squealing as she left the driveway in her car.
"She walked in right as we were cumming, your first spurt almost went up my nose, I didn't know what else to do so I just put you back in my mouth," said Lisa, she was giggling so hard.
"Do you want to finish, I mean it's not like we can get in any more trouble," I said, rubbing her thigh.
"I like your way of thinking, I'm on top."
Lisa sucked me long enough to get me hard again then straddled me, taking me inside her then began to ride me. Being able to reach up and play with her breasts as she fucked me was wonderful, I was glad I'd already climaxed so I could keep the sensations longer. By the time we'd both cum again we both had a sheen of sweat on our bodies, Lisa collapsed on my chest as she caught her breath.
"I kinda lied to Mom, I think I am in love with you," I said as she kissed my neck.
"I know you are silly, I was fighting it but I feel the same. I love your cock, I love how attentive you are to me. I just hope Dad doesn't flip."
"Want to shower with me and we can clean up my bed too?"
"Few more minutes, I like this."
We barely got my sheets in the wash and managed to be sitting together on the couch when Dad got home, Lisa was snuggled up against me. When Mom came into the lounge behind Dad, she made us separate.
"What's this about Gail, what do you mean they've something to tell me?" Dad said.
"Marcus and I have been having sex, we were bored and really frustrated and it just happened. We're not sorry, we love each other, we're happy," said Lisa, her face stern and defiant like before.
"First of all, lose the attitude, you don't need it sweetie. I mean, is that it, you're on the pill or shot thingy right Lisa? I know you're both clean, I hope I taught you well enough for that," replied Dad.
"I'm on the shot."
"You, uh, remember when we first got together Gail, what I told you then, the things we did?" said Dad.
Mom's face, angry the whole time, suddenly softened and looked embarrassed instead.
"Fuck. It's been so long, I had forgotten," replied Mom.
"What, what are you talking about?" said Lisa.
"Well, I might as well tell you, explain why you're not in a world of trouble right now. When your Mom and I met I was sleeping with your Aunt Chloe. I was honest with your mom and well, it turned her on, led to things I'm not telling you about just yet but this, keep it out of sight, do a better job of cleaning the bathroom and I can't say this strongly enough, tell nobody outside these walls,"
"I'm so sorry kids, if I'd remembered I wouldn't have reacted the way I did," said Mom.
"Aunt Chloe is stunning, can't say I blame you Dad," I said, laughing.
"That she is but we agreed to cut our relationship off for your Mom, is nothing we regret."
"So what now?" said Lisa.
"Well, your Mom and I are going to have a long chat, you two can relax okay? Like I said, we don't want to see it so no fucking on the couch, try and be discreet about it but I support it," replied Dad.
"And no intentionally getting into trouble so we send you to your rooms," laughed Mom.
We all hugged, Lisa and I went to my room while Mom and Dad went out onto our deck with the wine Mom had bought.
"I hope you don't expect to sleep tonight mister, I'm fucking your brains out," said Lisa, grabbing my ass.
"I'll go make the coffee..."
