He argues with his sister and initiates her in sex to the beast

An argument with his sister has led this kid to find the decision to punish her for everything she has done. So what he does is kill two birds with one stone and fuck her, something that will allow him to have a pussy at his disposal whenever he wants. He starts her in sex in a brutal way, first with a fuck on the couch where he ends up with a run inside her pussy. Then he fucks her in other positions and officially turns her into his particular whore, something that she doesn't dislike at all.
