I can only watch as the buff gym trainer gets ready to give my wife the workout of a lifetime... My wife just opened her own yoga studio and on opening day I attend a men's-only class that she leads. I'm enjoying the sight of my sexy wife showing off her moves when I notice I'm not the only one enjoying the show. But realizing the other men are thinking dirty thoughts about my wife—with me in the room—doesn't make me angry. It excites me. If other men just thinking about my wife while I watch gets me this excited, how would it feel if they went even further? When I tell my wife about my fantasy, I expect her to be upset. But she reveals she's also had thoughts of being shared with other men. She soon propositions a muscular trainer at the gym and, before we've even figured out the ground rules of this arrangement, I'm watching a stranger tease and undress my wife. Will going through with this ruin our relationship? Or will watching another man take my wife in front of me be everything we fantasized about?
