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.
He's lucky he didn't find his sister's hair on his razor. Such a beautiful sister could be taught a lesson and taught a lesson. Looks like she'll be leaving him hair more often now.
