Przyrodnia siostra uczy zabawy z kutasem i spermą

It's hard to see my stepbrother because I'm always giving private lessons at my students' houses. Today I left my room ready to go to a student's house and my stepbrother was sitting on the couch. I greeted him and he did the same. He kept staring at me and I asked : "Why are you staring at me so much, do you miss me?" And he kind of says yes. I think it's cute, his manner is charming, if I had an adopted stepson I would be just like him. He asks me to lie down with my head on his lap so he can pet it. He starts massaging my head and I feel ticklish, and we talk about the fact that his girlfriend isn't giving him pleasure, and then I feel his dick start to get hard and I ask, he agrees because I won't stop moving and he can't control himself. I tell him that we can keep a secret and that I can make him relax and cum.
