If I found out my sister was a slut, I would have pulled her in the asshole, too. For these guys, getting their asses handed to them is commonplace. Although for the look, they break for a few minutes, but when a couple of drops of lube appear - they quickly sit down anally on the phallus. So this little sister is nice to feel like a courtesan, to show off all her skills in front of her brother, to let him cum in her ass. Every bitch dreams of being the best at it.
How I love this swingers fun! And the girls this time, all model-looking. Good for the men! By the way, did you notice how all three girls were hanging around the black guy? They saw that he had the biggest dick and immediately surrounded him with their attention. I would have felt sorry for my wife, but I would have loved to participate.
That one's poison.
