When my boyfriend and I decided to have some naughty fun, we didn't expect anyone else to be around. But as we were getting down and dirty, my stepmom walked in on us, completely ruining the mood. I mean, who the hell does that? But that wasn't even the worst part. Turns out, my boyfriend had been cheating on me with my stepmom, and she was more than willing to watch us fuck. I was absolutely furious, but my boyfriend just laughed it off, saying that it was all just a silly joke. But I wasn't laughing. I was livid. I couldn't believe that he would do something like that to me. And to make matters worse, his friend walked in right after, jerking off while we were fucking. It was a complete violation of our privacy, and I couldn't help but wonder what kind of sick fantasies my boyfriend and his friends had. I just hope that this is something that we can work through, because I don't want to lose him.
