Dad fucks his son's girlfriend without the boy finding out

The flesh is weak, and when this man is shot to death, a young girl with a tight cunt and a face of huge addiction cannot resist. The problem is that the girl in question has a relationship with her son and that is a very difficult hurdle. The man ends up giving a shit and fucks his son's girlfriend a lot in the same room where the boy is, so absorbed by television that he does not find that behind him the father is trapped and opening the hole of his girlfriend's pussy.
