After fifteen years of marriage to Ryo, I have grown reluctant to sleep with my wife because of my cuckold fetish. I desperately want to watch her writhe with another man’s cock inside her, so I find a members-only swingers’ club where husbands offer their wives to strangers. It is exactly what I have fantasized about, but membership requires bringing a partner. I persuade Ryo to enter on the promise that we will only watch, yet she eventually becomes captivated by the men gathering around her.
