My first mmf threeway was with my gf and her ex, hes straight im bi, everyone knew that going in. Drinks, hot tub, and then things started. He concentrated on her till he saw my cock, she coaxed him into sucking my cock. He went nuts, and then while he was eating her pussy, I ate his ass. Str dudes go nuts for that. He ended up fucking her while I fucked him. Very hot, next day he was a bit embarrassed I hugged him and said dude no worries.
