Several times when we have been in a MMF my wife has suggested to me that I should take the guys cock in my mouth after he has cum in her. Well I did this and got to enjoy the feel of a slackening cock in my mouth and tasting their mixed juices. This progressed to me getting the guys cock hard for her wanking him taking him in my mouth till he was hard for her to use. One guy contacted me after a session with us and asked if we could meet for a bi session. I met him and after some mutual wanking we went into a 69 and sucked each other while fingering each others asses. we both came and it was a pleasurable experience. Now when we meet him together I spend time fingering his ass while he fucks my wife i told her what happened with the two of us and she wants to watch as I get fucked in the ass. As we have used dildos and strap ons in my ass I am prepared to fulfill her wishes but the guy is not wiling, maybe someone out there would be.
