You're a naughty boy. Your sister has left the door to her room slightly ajar. She's only wearing a tiny top and a thong. You can't help but watch her, she's so sexy, even if it feels a little wrong. She starts to rub her pussy, not at all aware of your presence. You have a perfect view while she plays with herself. You even get a few pictures on your phone. You're nearly bursting out of your pants with how hard your cock is. It's all going well -- until she finally does notice you. She storms to the door and asks if you'd been watching the whole time. You sheepishly admit your perversions. Your sister is frustrated, but especially because she kind of likes that you were watching her. You assure her it's not weird that she liked it. You loved watching her. This is all natural. Your sister pauses before leading you into her room, taking off her clothes. She's been thinking of this for so long. She lies back on her bed and slips your hard cock inside of her. Your sister's pussy feels better than you could've imagined. You fuck her, making her tits bounce up and down, until you pull out and cum all over her. | Tags: brunette, long hair, big tits, big boobs, natural tits, role play, taboo, voyeur, fingering, masturbation, brother/sister fantasy, POV, virtual sex, cumshots
