Bi fun with a couple

I had often joined this Mary and Roger before while away on business and we had always had fun. On this particular occassion Roger was lying on his back with his wife Mary on her knees over his face being eaten by him.I knelt in front of Mary and kissed her and played with her breasts. She pulled me forward closer to her. I tried to keep my cock and balls away from Rogers face as I was now directly in front of Mary. She starting playing with my cock as I was fondling her breasts. Her husband was still underneath her eating her pussy. While we were kissing each other she then took my cock and slipped it into Rogers mouth. I was shocked but he certainly wasnt complaining and I was enjoying myself too. After a while she slipped down and Mary and Roger took turns in sucking my cock untill I exploded over Marys breasts. Roger then proceeded to lap it up off her breasts. This bought a whole new element to our friendship and threesome fun.
