It’s the first time they touch her pussy and she likes it
A game that she knew would end that way has ended that way. It seems that every time a bitch imagines a situation, the universe conspires to make everything happen exactly as she imagined. That’s what we can see here, because it’s the first time they’ve touched her pussy and she’s made it happen. Her stepfather had no idea and then she was giving him a blowjob. At that point and with an erection, then the only option he has is to penetrate her and make her enjoy. Give him a fuck like any man would give to any whore.
