He Finished Inside Me In The Gym

I'm picking Toby up late from his boxing gym, but when I get there he's still working out.  I tell him to take a shower and find myself wondering around the rooms while he washes himself.  I find myself outside of the showers and my curiosities get the better of me.  Soon I'm watching him shower naked and I'm ashamed to admit it turns me on.  I wander in to the room and try my chances and soon we're doing something very naughty.
