Your knees go a little weak as she walks to you, a lump forming in your throat as she gets close. Your sister rests her hand on your chest, smiling up at you, "Mmmm. You know. Mom and Dad never let me have a boyfriend. And it is getting pretty annoying fingering myself every night. I really, really just want someone to show me how it's like to have sex," her hand reaches down to caress the underside of your erection, then pulls the foreskin down, "And it seems to me, bro, that you're up to the challenge." She whispers into your ear before biting it gently.
You smile and respond to her actions, wrapping your arms around her and kiss her neck. She's your size, and your twin, so every part of you that feels good to touch drives her wild. Your heart races in your chest as the two of you move to the large couch. She falls onto it first, looking up at you, her legs wide apart as she grins a little. "Mmm, think we should put a rubber on? I don't have any pills." |
