I don't see this being my fault at all but my buddy of 25 years is pissed at me

Last night my wife and my buddies wife went out on the town. I stayed home and went to bed early. They both came back here and kept drinking. My wife said to her friend, "follow me and take some pics" and tossed her the phone. They both came into the bedroom and my wife pulled back the covers and started sucking my cock. I woke up and seen them both and decided to enjoy myself. When she had me hard, I heard her say to her friend, "mount him". To my surprise she got undressed and got on top of me. She rode me until I let go a big load inside of her. We all decided to just let it as a fun experience, but she went home and confessed to her husband. Now he is pissed at me. This is my wife getting me ready for her to mount me
