Hot Summer Job/Just fuck her already
Your frustration growing, and with limitless opportunity, you push down on your waistband. You make sure to keep working your sister's clit as you step out of your shorts and underwear. Carefully maneuvering into position, you climb up between Bree's sprawled open legs. You envision coolly slipping your meat inside her while continuing to rub her clit but you aren't nearly that smooth. It's hard to balance and rub and manuever your cock all at the same time. It takes a moment of awkward shuffling, posturing up, lining up your dick, before you're ready. Holding back your fears, you thrust forward into your sister and tear through her virginity without even a hint of a warning.
"AAHHH!" yelps Bree. Her arms shoot out from behind her head grasping at the bed, her head and shoulders lifting up with a hard jerk. You quickly move a hand to her chest to keep her in place. "Riley!? Wh... what ar-"
"Hey Johnson, I didn't know dead girls could talk," you quip, as clever as you can be at the moment. You're already working your way into a rhythm, jamming your cock into your sister's tiny cunt with a few regular groans. She's so tight that it's good you took a running start. Might have been a lot more work to pop her cherry otherwise. It's also good that she's so slick, for her own sake.
Bree looks at you, clearly shocked, but doesn't say anything. Even with your dick in her she's trying to play the silent, albeit now very attentive, little dead girl. At least now you know the answer to your question. Your dick can wake the dead.
Your sister silently watches you, peering down past her mound as you piston into her hairless little snatch. She's watching so intently it's almost as if she's trying to figure out what you're even doing to her. Little gasps and shudders interrupt her unwavering observation. There's no mystery however. What you're doing is christening her flawless pre-tween cunny with your angry cock. You're still playing with her clit, albeit less earnestly, but the clarity you came to a minute ago is your main focus now: you just needed to fuck something.
You're already a horny teenager, but the past two days have gotten you so worked up. First the Callahan sisters, then your own sister, and then even Mrs. (or is it Ms?) Callahan have all teased and tortured you in their own ways. And not once have you gotten your dick wet. Bree is probably least deserving to be raped, but at least she's not fighting you.
Never could you have imagined your sister's pussy would feel so incredible. It's a tight squeeze, no doubt about that. She fits you like an undersized glove. An especially apt analogy since you can only fit about three quarters of your cock inside her comfortably. But your urges push you further. You tap your sister's cervix then lean forward and bear down into her. She whimpers at first, then yelps, struggling to accommodate you. Pushing her womb further up inside her, you force the rest of your rod past Bree's straining lips until you've fully bottomed out, your pelvis making contact with her soft vulva.
That's it. That's what you needed. A girl's tight wet embrace squeezing every inch of your cock all at once. Just feeling her quiver around your cock is enough. You cum with a sigh then immediately halt your breath. You fire again, but your seed is trapped. Pressed so tightly against Bree's cervix is sealing your cum within your shaft. But with the chamber fully primed, the next shot fires its way through. You can feel the instant your explosive seed forces its way past Bree's normally sealed entrance and fires directly into her womb.
"EEEE!" she yelps, the innermost part of her body dramatically violated.
You pulse a few more times, your spasms releasing the rest of your spunk into her vagina in a more typical fashion. Once your orgasm subsides, you remain still for some time, your cock at rest inside your sister. Nearly a minute passes before you slowly slip your softening member from your sibling's sopping snatch.
Rolling to one side, you join Bree on the bed staring up at the ceiling. It's only now you're reminded of Bree's bikini top, as you lay atop the knot tied behind your back. You definitely took this game of dares a 'little' far. The fact that she could have stopped you, but didn't, doesn't provide much solace when it's your little sister. You should probably say something.
"...wow."
That's the best you can manage? It's not good enough. Bree responds by pushing off of the bed and scrambling out of the door of your parent's bedroom, slamming the door to her room a second later.
Well shit.
