Just caught my sister in the backyard smoking a cigarette, guess who's going to be in deep shit! The little slut will do anything to keep our parents from knowing what a bad girl she really is. She doesn't even hesitate when I tell her I'll keep this between us if she sucks my cock. She pulls my dick out of my pants and starts sucking me off while finishing her smoke. Taking my cock deep down her throat I grab her head and impose her to suck me faster. Her mouth is so warm and inviting I love when my sister sucks me off. She jerks my cock as I cum all over her tongue, I love making her eat my cum, and she always swallows every drop. I'll keep this dirty secret from mom and dad...only because she sucks a mean cock
