had a 2 year relationship with a same-age bi couple in my twenties, until they moved away....used to love sucking his big cock with her and sharing his cum with a sloppy kiss at the end or fucking her while I sucked him or they did the same to me...over that time, all 3 of us occupied and came in every conceivable fashion and position possible...really miss them, she a tiny petite little thing and him slim and muscular.
