Married woman wanting a massage....

I responded to an add about a local woman wanting a massage today, since I'm off work today I figured what the heck. After she emailed me back, I realized that she probably doesn't do this much..since I searched her email address and found her facebook profile. She has a few kids and is married. I haven't mentioned anything to her about it..since she didn't say anything I guess she wants to keep it hidden. I am suppose to meet up with her in about 1 hr to give her a full body massage..and since she doesn't want to spend money, she stated that anything can go in exchange for the massage. I realize that I shouldn't do this after I found out she is married, however I am still gonna go through with it just to be alittle bad. Curious...does many women do this sort of thing, just to get a bit of excitement in their lives?
