I had an experience that was supposed to be a MFM threesome but very quickly morphed into more like a cuck thing except the girl involved was not in a realtionship with either of us. I was relegated to the sidelines as she enjoyed his huge cock and I wanked my tiny penis and watched. I would have preferred to be a part of the action but I must say I got off on my downgraded ( degraded role) Just one of my experiences on the road to me realizing I had an SPH fetish.
