Hi ltndude,
1. Working together might cause (future) problems. Then again: many people meet at work and have fine relationships, be it sexual or otherwise.
2. The fact that she is married is not your problem. Just fuck her: cheating women are the best.
3. Yes, she might. So you might make a temporary fool of yourself. So what? The only problem may lie in the fact that she is your collegue, and you may want to consider that, but otherwise imo there is no problem. If she's not just a flirt you get to fuck her.
4. Her husband is out of town a lot? Great! Then you can fuck her a lot! But how to get her into bed...? If I knew, I wasn't a cuckold...

ren?.
