The old minx didn't even look at the fact that it was her young son and made him fuck her in every known position. You could tell by her passionate cries that she liked the young guy's young body and his bouncy frisky friend. It feels like if she could, she would have swallowed not only the cock with pleasure, but the whole son. The mother was no stranger to sexual pleasures and taught the young seducer a lot.
Not exactly a good shot, but not a bad idea. It reminded me of my own sex with my wife when we were young. Everything was also neat and careful. Too bad they didn't film the end, how the guy came inside the girl.
