I am fucking a guy at work.

I am fucking a guy at work. I don't like him or anything in fact I dislike him most of the time. But when we are alone in the office. I will walk in there and pull my pants down and bend over the desk. He gets up un does his pants and fucks me with his huge cock for bout three minutes cums in me and then. I pull my pants up and leave without a word. Then I go into the bathroom masturbate and clean up. I have met his wife. She is very pretty and nice. It makes me feel bad but I still fuck him. I hardly ever fuck my husband unless he really begs for it. Then I will let him fuck me but I just lay there and let him get off. But I only do this if I am already full of cum from work. Then he says you are really wet you must be turned on. I tell him to get it over with. He has no idea he is feeling another mans cum.
