Have you fucked your ex-wife ?

For any of those who have read my True Story (My wife, Her friend an Opportunity) regarding my now ex-wife then you would wonder why in the world I would fuck her. Even though she drove me almost pure crazy back in the day plus I would never consider getting back with her, I sure didn’t mind the sex back then. Did I miss the feel of my dick in her soft wet pussy, the way she sucked me and her wanting me to fuck her in the ass, well HELL YEAH.
I mean it didn’t keep me up at night missing it or anything like that but the fact that I could fuck her and not have any further commitment was great.
The situation where I could come into town to have my weekend time with our youngest child and possibly getting her pussy on the side now and then (I have a girlfriend) just made it so naughty and hot.
She would hint to me on occassions and refer to us having sex but I had typically been ignoring her.
There was one time in particular where things coincided and I let it happen.

Now, on to the story:

I live out of town and I typically arrive early evening on my Friday but getting held up I arrived late at night one time at around 10:00pm. Since I stayed out of town I would stay with our kid at her place while she went off and stayed with friends all weekend.
Her plans had gotten messed up with my late arrival and, just like she did on a few rare occassions, she stayed home but left the next morning and would be gone the remainder of the weekend.
When those times happened it was completely plutonic and the only thing that happened was she would start an argument with me however, on this one occasion things progressed a little differently.

I finally showed up and it was close to our childs bedtime and once asleep I simply sat back on the couch and watched TV and didn’t even have sex on my mind. We each minded our own business and didn’t converse much except to talk over a few parental issues or like I said previous she would start an argument.
She was being unusually kind and cooperative this particular night but then again she always did run hot and cold and like I explained in my initial story you never knew who/what she was going to be.
We finished talking then she went into her room and took a shower while I continued to watch TV.
Like usual when I was sleepy enough I was going to sleep in our childs room. When she was done with her shower I heard her opening and closing her dresser drawers and rummaging around as she got ready for bed.
She came into the living room and sat down striking up a conversation and telling me how much she appreciated the things I did for them, etc, etc. I let that go in one ear and out the other because I’ve heard all this shit before and then the next day I would be called a heartless bastard. She remained sincere then just like other times when she was like this she got up and stooped over to give me a hug as a gesture of “friendship” and “cooperation”. I typically recoiled anytime she did this because I really didn’t want to be close to her or portray that I wanted to be with her.
