One of my hands pushed a lock of hair behind her ear. My sister’s eyes were looking back into my own, no emotion other than surprise clearly obvious upon her face.
“Jakey…” she ventured, finally breaking words into our impassioned sex-romp. “You weren’t supposed to cum inside of me.”
“I’m so sorry, sis. I, I Really didn’t mean to!” I pleaded, panting, notwithstanding my brotherly dick still wedged inside her warm, wet twat.
“No, Jake! You don’t understand,” she insisted, tones of anger and worry both rising in her voice. “I’m not on the pill! I told you this is a dangerous time of month for me!! Do you know what that means?!” she huffed, voice getting shrilly.
“Oh-my-god-sis!” I responded, hoping we could be on the same team here.
“Don’t You ‘Oh-my-god-sis’ Me! I asked you a question, you little brat! Do you understand what you just did?!” she kept on, a pouty wail starting to join the other emotions in her voice and across her face.
“I- I- I didnt mean– I mean, it was an accid–”
“No! You Dont Get to use that one, you little twerp! Maybe it was an accident when you peeked up my nighty, or fell on me on the couch, or maybe even when you stuck your disgusting little-brother-penis in me, but you heard me Loud and Clear when I told you not to cum in me! Was it an accident when you started tickling me? Or when you grabbed me and started making out with me?? I’m your SISTER, bro!” She shrilled.
I was speechless, staring up into my sister’s panicked eyes.
“Jakey, you just took my virginity! Not only did you kinda rape me, but you just Took your Big Sister’s Virginity!” Marissa’s pussy began to clinch my shaft, almost like she was using it to emphasize her final words in the most infernal of ways.
“I Didn’t rape you, sis! I swear, I would Never!”
“Well you certainly didn’t ask me either, little brother–”
“No– You were the one on top of me, sis! Plus You’re the older sibling!!”
“Fine– Maybe you didn’t rape me, but you Stole my virginity! Do you have ANY idea how hard it’s been through high school And College not losing it to SO many guys? And Chicks? Thank god butt-stuff can’t get you pregnant… But I was actually able to make it through the Craziest years of my life without losing it, just to have my Little Brother Accidentally steal it?! Do you have Any idea what that feels like, bro??” her voice broke into sobs, as her face fell onto my chest, warm tears spilling onto my skin.
I wrapped my arms around her shoulder blades and cradled my big sister’s sobbing head against my chest…. What would it feel like for a grade-A babe to accidentally lose their v-card to a sibling? Disgusting? Mortifying? Forbidden…?
“Well I did just lose my virginity to my own sister, so I kind of get what you’re going through…” I said softly, as I stroked her bare back.
Suddenly her last tiny sob broke into a slight giggle. “Jesus, Jakey, of course you’d be snarky at a time like this.” Her pussy squeezed tightly, before gently easing back. What the Hell was going on?
She lifted her face so that her chin rested on my pecs. My sister looked into my eyes again, their redness offset by a smile tugging at the corner of her mouth. “It’s SO disgusting that my own little brother just had sex with me… That you’re still inside of me… Oh Jesus, that it’s Your splooge, my own little brother’s DNA, that’s literally Painted all over my insides…” She bit her lip. “But somehow it’s also kinda romantic knowing that you just lost your virginity, too… And to your own sister, also?… I guess you’re really truly the only other person in the world who could ever know what that feels like… Being stuck in the exact same boat as me…”
Wow, were we really back on the same team? Was it that easy?
“But little brother, there is that one eensy, weensy problem…”
I waited on pins and needles; I swear I started to notice her pussy pulsing around me again, lightly.
“My last period ended 12 days ago… I’ve always been really in tune with my body, and I can tell that I’m ovulating today… Probably at my peak ripeness for catching, if I were to guess.” She was gazing softly into my eyes. “Do you actually get what that means, Jakey?”
I’m no dunce– there’s not an 18-year old alive who wouldn’t understand what she was getting at. But I had to say it to make it real.
“Sis, Marissa,” I started, feeling her pussy ripple down my cock as I said her name. “Ughhh, yess. Shit.. Sis, it means that you- y- you c-c-could have an egg floating a-a-arround in your womb.” My eyes squeezed shut, as Marissa’s vagina had come back to life with a vengeance around my meat, and all my worry and concern for what had just happened was in danger of being forgotten in the wave of sensual pleasure around my shaft.
“Yesss, little brother,” she gasped, a slutty, panting breath luring my eyes into looking back at hers. “And…?” she begged, sultrily.
“A-a-and, you could,” I actually gulped before saying it,” You could get pregnant. M-m-my sperm would, would mix with your egg, and. And then, I would have made you pregnant, sis. You would be pregnant with My Baby! Oh, Jesus, sis, what did we do!?”
“Oh no, you don’t, you little brat!” She said in a dangerously rising voice, whacking me on top of the head with a hardy slap. ” ‘What did we do’ my Ass! You Did this, you little twerp, and if we have to go back through it one more time, I’m going to wrench your dick off myself so that I’m your Last as Well As Your First Fuck, Capeesh!” Her Sister-pussy clenching again, as though on cue.
“Jesus, Sis, are you planning on wrenching it off with your hands or with your cunt, because it might affect my answer!” I couldn’t help but guffaw a laugh out at my own joke– there were SO many things still wrong with this situation, but somehow our sibling joshing wouldn’t be brooked.
“You Perverted, Little Shit! You Take It Back!” She whapped me several more times across the head, as I tried to shield myself. She was definitely pissed still, but I could hear a playful edge fighting its way into her voice.
I thought briefly about grabbing her hips and rotating us so that I was on top of her, but somehow I didn’t want to violate the cowgirl position she’d kept upon me since the whole encounter began. Instead, I managed to get a grip on each of her twisting, fighting wrists.
“Easy, Sis! Truce?” I pleaded, keeping her wrists tight to her hips.
“Truce? TRUCE?” She intoned dangerously. “Bro! You. Came. In. My. Vagina. Your SISTER’S Vagina. You took my virginity, and then you splooged your brotherly load in my vagina After I Explicitly told you NOT TO!”
“Yeah, But I didn’t Mean To, PLUS You Came a Bunch of times on my cock, First!”
“Yeah, But Me cumming doesn’t get me pregnant, Doofus!!”
“Yeah, well it takes Two people to make a baby, Plus we don’t even Know if you Are pregnant yet!”
There were a Lot of emotions surging through me, from my upper head to my lower head, and back. I was pissed, and Worried, and Confused, but Definitely Horny. I didn’t realize that last one had returned until noticing that my cock was rock hard again; not only that, but my cockhead was twitching firmly against something spongy at the end of my sister’s vaginal tunnel.
“Yet? YET? ‘We don’t know if I’m pregnant, YET’?? Are you seriously hard again, thinking about making me pregnant, Jake! I’m Your Sister! We have the Same mom and dad, you little Pervert! Cumming in me the first time was Horrible! Disgusting!! Getting hard thinking about what you did is even Worse!”
“I’m Sorry, Marissa! You just feel So good! You- you need to get off me!”
“Oh NO you don’t, you skeevy little Pervert! After everything you’ve done to me, we’re not finished here until I get some Promises out of you!”
“Promises? What the hell are you talking about, sis?”
“You Owe me BIG time for what you just did! If you don’t want me blowing the secret on how you raped your big sister and put a baby in her belly, then Number One: You HAVE to go get me a Plan B! TODAY.”
“Oh my god, Sis. I just realized. They took plan B off the shelves back in April… The fucking governor signed some bill. You can’t get Plan B in our state anymore!” My mind was racing. I had heard about it, and thought it was a stupid political decision at the time. Now it seemed criminally insane. The nearest state I was sure still had Plan B was maybe 12 hours away.
“Holy fuck… you’re fucking right. What the FUUUCK?!!” Marissa shrieked, her voice reverberating off the walls. If she’d have kept on, I’m sure the neighbours would’ve called the police. “What are we going to Do, Bro?!” My naked, elder sister demanded, leering down at me, worried once more.
“Calm down, Sis! We’re going to be alright– Like I said, we, we don’t even know if I got you pregnant!”
“Look at where your penis is lodged, Right Now, Little Brother!” She lifted her crotch just high enough to grab my wet shaft with her hand. “Your dick is covered with your semen, because you came in your big sister’s pussy! Twice! Two Times! After you Knew she was in her Fertile time of the month!”
“No, sis! I only came once, I swear!”
“Shut Up! Listen to what you just said! ‘You only came in your sister’s vagina once!’ Don’t you know how Horrible that is??” She let go of my shaft and landed her pelvis squarely back on mine. “You need to figure out a way to get me a Plan B, Pronto, Jake! That’s Rule number 1!” Her pussy clenched like a vicegrip around the base of my cock. “Rule number 2: We don’t mention this to Anyone EVER, Got it?!”
“You think I Want people to know that I fucked my big sister?! I’m going to have to lie about how I lost my virginity for rest of my life, Sis!”
“AHH!!” She Shrieked in frustration. “God Damnit… That’s actually exactly what was running through My Head… you romantic, little pervert.”
Wtf?! Did Marissa just call me romantic?
I felt her pussy start to twinge again. She ran her fingers lightly through my hair, drawing my gaze back to hers. Her eyes were showing something other than the anger that had burnt fiercely there seconds earlier… they almost looked like they were longing.
