Marissa Mae has sex to keep her stepbrother quiet

Marissa Mae gets caught by her stepbrother at home, talking on the phone when she's supposed to be at school. He brought a camera so he had proof of her misbehaving. It's not like she can afford skipping school either, her grades are terrible. What can she do to make sure he doesn't tell her mother? Well he hasn't had sex in a while so if she helps him out he will keep quiet. Well, it ends up that's a deal and before you know it she's sucking and gagging on his cock before taking it in her pussy which is also where he puts his huge load.
