Well apparently very much wanted to fuck their mother, so he fucked their brother / son, I do not know what to call it, but judging by the moans from both sides they like this sex very much. Although in principle, why be surprised if the brother is such a yadda, then of course sex with him would have to both taste, and so it turned out. I'm surprised my dad didn't join in, because it happens all the time.
Some lady is completely unsightly! I just do not understand why the man with such enthusiasm pulls her, I probably would not get up on her at all!
