Apparently the husband had his wife so worked up that she was ready to put any hole in her body just to have a rest, so he found a neighbor, whom he periodically fucks in her presence. At the same time she is completely uninhibited, and gives in the ass, and in all the slits that he asks, because his large cock she likes thoroughly, judging by her moans, even more than thoroughly.
Daddy wasn't going to do anything like that with this daughter, but this bitch sat on his lap all by herself. And when the selfies started, the man naturally got a hard-on. Who is going to resist when they offer to touch his breasts? And then he just lost his head. But he stuck it in her like a grown-up - in the asshole. The pussy is for young men, and the slit is for men to dip their dicks in it and stick it up their asses. Cum in a chick's asshole is a lot of fun.)
For an Asian woman, the woman is very juicy and ripe. With all the diminutiveness of her build, her ass and legs look great in the cradle position! And besides experienced, funny and without complexes. Who would have refused to have fun with her? What's interesting, the man was never shown, unless you count the close-ups of his dick! So what's the basis for assuming it's the son?
For another man.
