You and your lil stepsis are sitting and watching a scary movie in your room and your stepsister keeps getting anxious as she anticipates the next jump scare. You'd never say this out loud but your stepsister is really fucking hot. She's really blossomed as she's gotten older and her tits are way bigger than any of the girls in your age group. You like taking the piss out of her for hiding behind a pillow - like that's going to help - and you watch her tits jiggle as she playfully hits you. Little stepsis is really scared now though and she begs you to let her snuggle up to you. You protest but you don't really mean it... you love feeling your step-stepsister close to you and, as she snuggles closer and closer, you're not sure if it's wishful thinking but you could've sworn you could feel her touching herself...
When the movie ends, your stepsister is well and truly shook and she pleads with you to let her stay in bed with you. You're unsure... after all, you've been trying to make your massive hard on go down ever since you imagined her touching herself... you've no hope if she stays in bed with you! But of course, your protective big step-brother sense of duty kicks in and you relent. She climbs into bed with you and assumes the little spoon position but there's no way you can be big spoon without prodding her with your throbbing cock. Realising what's going on, your stepsister smiles and decides it's time to act.
She climbs on top of you and puts her finger up to your lips, shushing you, saying that you need to be careful not to wake up step-mom and step-dad. She starts grinding on you and talking dirty, telling you how she's been having these thoughts about you for some time now and how long she's wanted your cock. Taking off her cute pj's, she guides your cock into her tight virgin pussy, trying to keep quiet while she bounces on your cock. She tells you she's all yours now and makes you promise to use her wet hole every night from now on. She begs you to cum inside her and as you pump your seed into her ripe cunt, you tell her you love her...
