I work at a local gym. After I started dating my boyfriend he got a membership there. One night we fucked in the gym after hours and it was very exciting knowing how much trouble we could get into.

After a few weeks one of the regulars caught us in the act. The next day he was in and confronted me about it. I tried to deny it but it was pointless. So instead, I fucked him in the gym too and to this day he has stayed quiet about what he knows.

I felt bad at first but then actually a little excited. I had never thought that cheating on my boyfriend for any reason would be fun for me but it was.

Six weeks later and I've fucked half the members in the gym and my boyfriend has no idea.
