I have a friend who thinks I fucked his ex wife

I have a friend who thinks I fucked his ex-wife. Truth be told, she called me to fuck her - 3 years after their divorce. Being that I am a good friend, I went to the toilet, jerked a couple of times, then decided not to go. In the following days, I jerked intensely. In my mind, I fucked her in all possible ways.

1. On the bed
2. On the table
3. On the washing machine
4. In the shower
5. On the floor
6. In the Garage
7. In the car
8. On the beach

In my imagination, I literally fucked her in all holes and covered every inch of her body with cum. However, I remained a good friend and refused to put my imagination into action.

Unfortunately, she did not take it well. Offended by the rejection she made sure that he found out about her open invitation to me.

My friend tries not to be judgmental, to my face. Officially he believes me, but I know he does not in fact and talks trash about me behind my back. He talks a lot. I mean, really a lot.

He is again married. One thing for sure about people is - They always chose the same partners when they decide to change them :) Mind-blowing, I know. Anyway, his new wife wants to fuck me. She gave me a "Sheron Stone" legs split. I can see that she is already desperate about the idea, and puzzled - disappointed by my rejection - lack of action.

I am thinking. What do you think? I am already found guilty and sentenced to carry the shame for a crime I did not commited. Should I at least take the benefits? I mean, if that MF did not told her that I fucked his ex wife, she probably would not have the courage to show me her attentions ?
