wife wants me and another man to fuck her at same time she never has tried it. or a couple and we switch off

I have doubled using the guys wife to make the husband happy. She is a co-worker & I was his birthday gift from her. He was made to watch me use her then he was told he could join in. We used every hole in the room including his & mine. She knew he was a closet Bi & that I was as well. This is a continuing adventure.
