This happened several years ago.
Not getting what I needed at home (wife and I were going through a rough patch), I created an account on Ashley Madison. It didn’t take long before I was chatting with a woman who called herself PhotoMama who lived just a few miles from me.
Chatting turned into flirting, which turned into sexting with pics (no faces). She had an amazing imagination, a killer body and (OMG) gorgeous D cups. I was hooked. I asked for a face pic, which she happily provided. It was then that I learned I had been chatting and sexting with a good friend of my wife.
After a moment of debating with myself, I let her know who I was. At first, she was shocked and embarrassed, but I set her at ease and asked her out for coffee, which she happily agreed to.
Instead of coffee, she offered to drop by my gym as I was working out. The gym in my building is small, sporadically used, and has a couple rooms off to the side on top of the bathrooms that have saunas.
