When I ride my man, stomach to stomach on top, I like a girl to lick my bottom, tongue inside... is that normal
Maybe just your kink, sounds like if you can get a woman to be a third it would be up to her. If it were you looking for MFM, that would probably be easier to get.
My boyfriends wife has a number of times rimmed he and I while we're 69 sucking each other...OMG, it feels so good. Then she breaks out her strap-on and things get really fun.
