(This video is a bit cheaper because it's shot on my phone rather than my filming camera!) Your annoying little step-sister is back at it again, begging for cock in her mouth! You're trying to relax and play Mario Kart but she just will not leave you alone, reminding you that your step-parents told you to help your step-sister out so she gets what she needs at home and doesn't go out looking for it in the streets! You finally relent and allow her to start sucking your cock, admonishing her when she gets too noisy and enthusiastic as you try to concentrate on your game. As your step-sister sucks and plays with your cock she says that your step-mom told her you got a girlfriend recently! Your step-sister teases you about your new girlfriend and asks if she's sucked your cock yet, and when you admit that you haven't got that far yet she says she bets that she's better at it than your girlfriend! And what's more, when you finally do get your dick sucked by your gf, she bets you end up just thinking about your step-sister! You tell your step-sister off for being gross and annoying, but she just giggles and continues sucking you off, waving her feet in the air behind her as she bobs up and down. After a while she's really getting into it and removes her sweatshirt to fondle her own breasts, even pulling her top down to expose her tits. You're shocked and tell her to put them away, to which she responds by teasing you for being so weird over seeing her tits, when she's literally been sucking your cock for month's now! She keeps her tits out as she sucks your cock, and you warn her that you're suddenly really close! Your step-sister laughs at you and says it was clearly seeing her breasts that's got you so close to the edge currently, and calls you a pervert for needing to cum over your step-sister's tits! She bends down again and sucks you off quickly until you flood her mouth with cum, then she goes right back to teasing you about your new girlfriend until you tell her to get out and stop annoying you!
