Thanks guys, yesterday I was too tired to report you guys this, but now I've slept a good night and can't wait to tell you:
Just while I was in the middle of writing my introduction here, I received a phone call from the HB that was once a very good friend of my wife, but their friendship wrecked because she busted my wife and told how she'd been cheating on me. Let's call her S and my ex-wifes another very good friend HB M
S is married, and I know her husband by name and face, but we are not that good friends, so I do not feel loyalty towards him. While S and my ex were close friends, we used to go out together sometimes, three of us. She's been playful and sometimes she has wanted to kiss me and stuff. After she'd been very drunk she has confessed that I turn her on

So I knew I had chances to get her laid.
We have gone out for a couple of coffee sometimes, two weeks ago we agreed to go to a cup of coffee. We went to a nice coffee shop, chatted and after it I asked if she was busy or if we could go and drive around. She said it would be nice, so we went to a lake coast and walked around for half an hour. We agreed that she would come to visit us so our kids can play together. She visited us with the kids at that saturday, they stayed for few hours, we trained dancing together (as friends, of course) and I made good meal for us.
Next friday I asked if she could go out at evening with me. We went to a karaoke place, sung, danced and laughed. I kinoed her quite a lot, when my hand went to her neck she resisted for a couple of times but later she accepted and even gave a couple kisses. I told her later that night that I will fuck her some day
After that evening she said she feels she's a bad person, but everything is cool at home
So she called me ( friday evening around ten ), she was a bit drunk but I think she faked a bit just to not sound so slut:
S: Hi, hope you don't mind taking a bit drunk phonecall?
Me: Not at all, I allways love getting phonecalls from you honey!
S: By the way, my husband was jealous over our last restaurant night! He said He can smell Axe!
Me: Yeah but it's not Axe I'm wearing, it's Dior Homme Sport
...
S: So, I'm here at a cottage at a lake, really nice place. I'm here with my friend T, you must remember her. We're about to bath in sauna all night long, sauna is warm but there's no-one to wash back
Me: Ok, I'll think about it. I don't want to drive because I've had two beers and one drink as well. Maybe I'll call a cab and drive there!
S: Great, it's (she gave me driving instructions).
....
I drove there in a taxi, and called while I was walking the last 200 meters in a dark road leading to the cabin.
S: Are you really coming?
Me: Sure, I'm on the road, I'm just about to get there!
---
The ladies were a bit drunk, but not very much. They wanted to get food and the other lady, T, said she'd want to go and sleep. Ok, we made bed to her and I made steaks for us, and then we went to sauna, me and S.
I kinoed S quite a lot, we danced around fire while making steaks and so on, I kinoed her in sauna as well. She's married but I know she wants me, and that was the only reason she asked me to come over.
She did not respond much in sauna, after a while she said we should go an swim in the lake. The water is quite cold at this time of year, so I grabbed her hand and put it on my erected dick saying: Allright, we can do it but this will not stay this way after swimming

She was playfull and joking, we went out at the lake and I swimmed a small round, she waited at the shore laughing.
We went back to sauna, I was still hard so I said to her: Like I said, this would'nt be here after swimming (putting her hand on my hard cock). She laughed and said yeah right
Then we went to sit up in sauna and I said:
I promised to wash your back so let's do it
I took warm water and soap, washed her neck and back very slowly and gently. She grabbed my hand and wanted more, I will not write any more details but you can imagine yourself
So, I've been developing this relationship gradually, at daytime I'm just purely friendly, our kids play together and stuff. I listen to her worries, encourage her and stuff! It's almoust like a LJBF situation. But at evening when we meet, I'm all in to get her sexually aroused. Seems this strategy has worked wery well!!!
She was the one to ask me to go over, I did not need to try to get in her pants

She even confessed later that night she had decided before the phonecall she was going to cheat her husband with me
Now, theres the other friend HB (M) I need to work on, my ex has asked M to cut our son's hair next weekend, so I can start playing and she has given me to opportunity to start without her knowing it!
I do not know if I'll ever tell my ex what I've done but regardless of that It makes me feel very nasty to fuck her friends. Revenge feels so good
Yours,
Daddy
