Dad, it's hurting me a lot, is that normal?

His father was a true degenerate. he is the typical man who does not take "no" for an answer. when he asked his son to eat his mouth, he was not satisfied with just giving him a blowjob, he actually fucked his mouth. but that was not enough, for him to be a complete he had to put it in his ass, which surely would be a virgin. the boy accepted and got down on all fours while his father grabbed his cock to penetrate him. the boy's grimaces said it all, not many cocks had entered his ass to say. but once he got her to come in completely, everything was much easier and the boy really enjoyed it.
