It's bad luck for a father like that to have a daughter. In addition to the fact that he does what pops into his head, so also teases. Everyone has their own methods of punishment, so the blow job and subsequent sex I'm not surprised. I poured a lot of sperm right on top of her. If this happens often, we do not know whether the daughter will deliberately harass her father, or just occasionally zabrilize him after another slip-up.
She's really got it in for her brother. There's no point in arguing with her, telling her off. So at least he played out all his anger during sex by pounding her between her big buns.
