Caught Cheating: He Joins in on the Unexpected Fun

Now imagine your girlfriend is home, and you live in a shared apartment with your best friend. You don't think anything of leaving them alone; after all, they're your girlfriend and your best friend. But then you come home, and your girlfriend is lying completely naked, half in the oven with the cleaning fluid still in her hand, and your friend is fucking her from behind. That's exactly what happens to the guy when he comes home and catches the dark-haired, busty slut enjoying another cock. But his reaction is actually pretty cool, because he's always wanted to have a threesome with his best buddy, so why not with his girlfriend?
