Watch

Part of me is screaming to step in and stop this, but I'm transfixed. As I'm watching my wife's ass cheeks bounce with each of Kenny's thrusts, my cock springs to full attention poking through the front of my boxers. Without even thinking my hand is drawn to my cock and begins to slide up and down my shaft.

I creep closer, I now have a better view of Samantha's small firm ass and her pussy as Kenny more and more quickly thrusts two fingers into her wet folds. For some reason seeing these two women who I have known since we were in grade school fucked by the teenage boy is really turning me on. I can't help it, a moan escapes my lips.

Kenny turns and looks at me. He looks shocked and maybe a little scared for a second until he glances down and sees me stroking my throbbing member. He smiles and says, "Hey man, don't waste this chance, this hot pussy is just waiting for a cock." He takes his hand out of my sister-in-law's now dripping folds and slaps her ass. "I haven't been in her or anything man no sloppy seconds, all yours. You won't regret it."

Now that he knows I'm here I don't know what to do, even though he's fucking my wife it's hard to yell at him now that he's seen me jerking off to it. Neither of the women have said anything other than moaning I don't even know if they're awake or just passed out drunk. But Samantha's pussy is almost calling to me I can almost feel what her hot tight vagina would feel like wrapped around my eight inches of meat.
