You're my little sister's best friend. I haven't seen you in a few years, but you're back in town and staying with the family for a couple weeks. I don't actually know *why* you're here, but I could care less. Sis bailed on you to go sleep with her boytoy, and now you're on the couch in the den watching some slasher flick, while I heat some leftovers for my breakfast in the kitchen. I work nights, and this is the first I've seen of you. You waved and yelled a half assed "hello" over the couch back when I walked in, but went right back to your show. There's no one else in the house, and won't be for hours.
I finished heating my food, and started to walk towards the couch, meaning to ask what you were watching. I slowed as I came around the side and you came into my view. It had been long enough since I had seen you that I wasn't quite sure what you'd look like. What I saw was not what I was expecting. You were sprawled out on the couch, half hugging, half humping a pillow. Facing away from me, with your ass in the air. It was glorious. You were wearing these fluffy white shorts that *barely* covered your ass. I thought I caught a glimpse of *red* under there too. That little bit of pantie info hit my brain like a spike and I couldn't help myself from moaning, just a little. Deep, and under my breath, almost a growl.
"mmm"
You noticed. As you started to turn I was forced to tear my gaze from your ass and start to take in the whole. You had been lying on your stomach, face in your phone, but now you were turning and sitting up and I could see several things all at once. Two of those things were your pierced nipples. Those were riding on two other things, your large, round tits. All four of those things were bundled into this ridiculously tight crop top t-shirt and were begging with all their might to be free and have attention. I struggled to simultaneously drag my attention up to your face, AND move to stand behind the couch to hide my growing erection. You were sitting upright now, cross-legged on the pillow. The way your legs were folded in those shorts, there was red cotton visible through both leg holes. I could see it in my lower vision, but I couldn't look down. You were staring right at me, half smiling. As if waiting to see if I'd look. I almost did.
I blinked, shook my head and pointed at the empty wine glass on the coffee table.
"I'll trade ya. Get you a refill while I'm up if you set my plate over there for me"
You nodded and said softly, "Ok". As you leaned over to pick up the glass I got a chance to really look at all of you, finally. You'd come in a little thicc, with the previously mentioned fat ass and hefty milk sacks, but now I could see you had the tummy and thighs to go with them. Well padded in *ALL* the right ways. I had been hard. Now I was fucking *diamond*.
Trying to control my breathing and my sight, I completed the trade and scurried for the kitchen while you set the plate down. Trying to think straight, I stood in the kitchen and took several deep breaths.
I had seen a few other things as well. A couple tattoos, all familiar symbols. And a single string tied around your ankle. I knew the string was your own fucked up purity ring. Never got the context on it. Just knew it meant you were a virgin. And I remembered a slurred, drunken proclamation when we were younger that you were "Saving yourself for your rapist". I hadn't believed it at the time, but every one of those symbols screamed in one, very clear voice "RAPE ME, FUCK ME, USE ME". You'd inked yourself literally asking for it, and yet... still asking. Not anymore sweetie. Time to pop your cherry.
I grabbed a few benadryl from the cupboard and crushed them into your wine. Hoping that and the wine would zonk you out cold in a jiffy, and that you wouldn't notice, I walked back to bring you your glass and asked for a recap of the film. I could see the disappointment in your eyes as I sat on the other couch instead of next to you. I smiled to myself as I ate, watching you pout over your glass as you recapped what you were watching. Sliding out my phone, I texted my boss that I wouldn't be coming in that night.
You were out before the credits rolled. I waited till the movie ended, and muted the tv. I left it on some cable channel for the light.
You'd gone back to sprawled on the pillow shortly after you'd finished the wine. Standing, I could see that in your efforts to get comfortable, your tits had popped out from under the shirt and were squishing out on either side between you and the pillow. Your ass was just as in the air as before, but now I could fully see your red cotton thong trying to cover your lower lips. I crouched next to the couch in front of you and listened to your breathing, watched your face. I gently stroked you on the arm, then the face, the leg. Watching your reactions, judging what I could do without waking you. I judged it to be a lot. You were fucking out.
Slowly, I pulled the shorts down. Inching them bit by bit I had to stop regularly to stroke my cock at the sight of your fucking dump truck swallowing your thong. When I had them far enough down, I reached down and started rubbing your pussy from over your panties. I had to push a bit, but you started moaning gently in your sleep, drifting into a wet dream at my touch. I pulled the thong aside, and got my first look at your unused pussy. It looked amazing, so leaning in I caressed it, pushing my fingers ever so slightly into your hole. When you moaned, but didn't stir, I started licking your lips, pushing my tongue into you and stroking myself beside the couch.
When your cunt was good and wet and your moans had gone up half an octave, I climbed onto the couch behind you. Sliding my cock on your now sloppy lips, I started to work myself toward an orgasm. When I was damn near there, I grabbed your hair with one hand, pointed my cock into your pussy, and slammed myself into you. Lubed and with force, I ripped you open, already cumming into your womb on your first stroke. You woke, screaming, no longer a virgin, and hopefully bred. I dropped on top of you, wrapping my arms around you, pinning you on the pillow. Without *quite* the force of the first thrust, I start pumping my spunk deeper into you, still cumming as I do.
