Now: So when his wife came to work for us, we were on the same team, but she was quickly moved off to another team. No sweat, it's my mate wife, all good. However we started talking, going on lunches together and drinking after work (office enviromentment). After a while we started talking about life, and decided (during a rather filthy conversation) that'd we'd mess around. So during lunch times we'd go for a walk and get "lost" in a stairwell, where she'd either play with me, or I'd play with her. We started meeting outside of work, getting off with one another etc.
Then, one night, we got a hotel room, and we absolutely fucked the living lights out of each other. The best part was looking into her eyes as I came inside her, just as she came; I had a very intense orgasm, as did she. Both soaked we lay there and talked for a while, cleaned ourselves up and then left. After a couple of weeks, for some reason, we grew distant. I think it was more regret on her part than mine.
Now, when I see her walking around the office, I just want in again. Whenever I see her my cock twitches, I look her up and down and just think "God, I want to be in you so bad."
What do I do? Any/all advice welcome, as long as it's not just attacking me (takes two to tango).
