Decide that the damage is done so you should take advantage of the situation
From Create Your Own Story
You think hard and long about your decision. There was a good chance that Rachel was on birth control cause she's already at that age right? You may never have a chance like this again. Chances are if she WERE to get pregnant then she was already screwed. However, a little part of you gets excited at the thought of impregnating your sister. A little spurt of precum spurts out the tip of your penis, and you relish in the thought of releasing your load inside your bitch sister and ruining her life.
"I guess there's no use crying over spilt milk. We've already crossed the line and she might be pregnant already but at this point, we might as well enjoy our selves until she wakes up." you say to the group. The guys are unsure for the minute, but you decide to lead by example.
You step in front of your sister's pussy and nestled your throbbing shaft on the slightly parted wet slit of her pussy. You slowly and ever so gently began rocking your cock back and forth against her clit. You watch as your hard throbbing dick sawed up and down the length of her cuntal crevice. The weight of your cock gently parts her soft lips wider as you watch your dick slip deeper into the hairless crack. It was so incredibly smooth and slick. It felt hot and moist against the underside of your dick. You lift your sister's legs up and bend them all the way back till her knees are touching the sides of her head.
You quickly increase your pace, each thrust more pleasurable than the last. Your friends look in awe as you mercilessly pound your sister's hips with yours. Sebastian walks up to your sister's face and lines his drooling cock up with your sister's mouth.
With Rachel on her back and head tilted backwards, her throat straightened out giving him the ability to utilize her face like a pussy. With one push, he sunk his entire penis straight into your big sister's esophagus. He fucked mercilessly into the bitches' skull from this superior position while roughly manhandling her boobs. In her unconscious state, all she could muster out of her mouth were large streams of saliva every time he pulled his dick out of her face. He piston-fucked the whore's skull while large gobs of spit and drool ejected from her mouth on every out-take. He slapped her face and fucked his cock as deep into the bitch's face as it would go, in and out, for 15 minutes. Finally, after the savage face-fucking he'd given her he felt his balls boil with spunky hatred. He slammed once more as far he could go down her throat and came five massive gobs of semen right down her gullet directly into her empty whore stomach. Rachel choked as he bypassed her normal swallowing mechanism and ejected his cum directly into her stomach by way of her esophagus.
As he pulls out, a thick web of slime leaks out between her lips and up to her nose and fore head. Her mascara was completely smeared and her face a mess. Unable to hold it any longer, you slam forth brutally, no longer concerned with your sister's well being, you squirt your sticky spunk into the depths of your sister's pussy, each shot glazing her cervix over and over with sperm.
