Your stepsister beth wanks you off

Beth is trying to read a book, but her stepbrother interrupts her, ogling her bare bum and just generally being a nuisance to her. Suddenly, he pulls out his dick which shocks her. But Beth, being a good but naughty stepsister, invites him to rub it on her arse. When he does, she makes fun of him saying that's probably the first time he's ever touched a girl with his dick. As she continues to try to embarrass him, she takes his dick in her hand and strokes it, then unties her top and plays with her tits, and then pulls off her thong to show him her pussy. "How pathetic," she says, "that the first pussy you're going to see is your stepsister's!" After rubbing it some, Beth offers to jack-off her stepbrother as she continues to rub her pussy. Beth cums and then shoos her stepbrother away.
