Are you serious??? Stepson cums right in my face

My useless, small-dicked little stepson was bullied again at vocational school. His classmates showed him a gangbang video in which his stepmother was getting it on really hard. And now this slob would like a turn. After I’ve given him a good beating, he’s finally allowed to take out his little dick and jerk off. And because I’m a good stepmother, I even suck his cock. But when he cums in my face without asking, my good nature is over… *Role play*
