My wife had never been willing to do anal sex until we did our first mfm, she was on top of me riding my cock and the other guy was rubbing her back and playing with her tits, and to my surprise when he started to slide his cock into her ass she did not stop him, she became super horny and went wild. It felt a little weird for me because of the accidental touching of my cock and the other guy cock as we both fuck her at the same time, but i love how horny it make her when we dp her. She claims when we dp her the orgasms for her are more intense.
