Incensed by their betrayal, you can't help but masturbate, your fingers rubbing furiously against your swollen clit, as your husband and stepsister fuck ruthlessly mere feet away. Their bodies slap together, her tight cunt gripping his veiny cock, as he pounds into her with primal force. She moans and whimpers, taking his rough treatment like a good little slut, until he pulls out, his hot cum splashing across her face and tits, marking her as his cheating whore.
