I've been playing with a couple over the last year, but it's hard to get together with them because of work schedules. They are both straight, but he's learned to be fine with me going down on him. It started with her and I on the bed in 69 (with my head at the edge). He comes up behind her and fucks her doggy style. He eventually started letting his dick drop down to my level... I'll let you imagine the rest.... I'm not into anal penetration, just oral fun. Love giving and receiving.
