It makes him see how his son fucks an old man

It seems that this father gets quite horny to see how his own son fucks an old man in a more than vicious way. she likes to look at him so he can be in front of her and delight in such a fucking. the son in question is the typical skinny boy who loves to taste a cock, whoever it is, because he's naturally lewd and kinky, just like his father.
