Married ladies always better for a few reasons.
If the communication is there, they are already getting that part of their life satisfied. They have the love and trust of hubby. I don't need to supply that.
I am taboo. So is she. That is something that hubby really can never be. I'm also usually packing a bit more than he is which she enjoys, but that just adds to it. It's the contrast. It's the freedom. It's the "I don't give a fuck, this is what I want to do" attitude, even though it's confined, its still liberating.
It is a connection, much more than sexual. To cum in another mans wife is a powerful feeling.
That's why I still do it.
