My X Mrs and I did alot of swinging [ Me 28, her 20]
Both of are/were Bi and enjoyed sharing cock and cunt together. One of her fetishes was age, both younger and OLder. Her Favorite Daddy was mid 50s average build and around 6" cut cock with all his pubic hair in tact. She was well trimmed, I was always kept Hairless [ long before any of you guys shaved your cock]
One day we decided to go to a ADULT nude beach [ no kids] The hot thing was the age diff. and that he had cock hair while I was hairless like a sissy . Both he and I got hard and showed for anyone to see. It was obvious that he was not her Mate, yet discreetly played with his man cock.
