In truth I was okay with it, even turned on a little by it. But it still came as quite a shock to learn that my boss and his wife were real swingers a...d that he'd been having sex with my girlfriend for years.

When I heard his breathing quicken, I was over come with lust. Was he going to cum? Was I going to make him cum? I was lost in the moment now and.
