Marriage is over after 7 years

My wife has always been very shy. Shy is very sensual too. We have been married 7 years now. I am 32, my wife is 26. I remember reading couples get tired after 7 years, and I always laughed. But when my wife told me last fall she was no longer happy I froze.

I tried to understand and asked. She said she met someone. They dated but they did not kiss or anything yet. But she was sure she felt romantic about that guy and she wanted to go ahead with him. I panicked and asked her to reconsider. We have no kids but I still wanted her and I wanted to live with her. She took time to think of it. Long time, maybe a week or so.

When my wife told me what she thought could work for us I did not know what to say. And she went ahead with that guy and she slept with him now. So I could only take her deal or else go and find myself a new wife. I did not like what she offered but we talked and finally she agreed she would make a video for me to see. To help me decide. She made the video on her phone and let me watch it.

My first reaction was disgust. It took time to sink in that my wife can do with that guy anything she did with me and then some more. But later when she left me to think I tried to find any arguments for staying with her.

I found the only argument for me could be taking revenge.

I said yes and she arranged for the guy to visit us and we got to know each other. He is a silent type though, so I did not learn much about him. He is and IT consultant with some industry. I am a book store owner. Not much in common to talk about.

The first time we did this was in our house and I felt awkward and out of place, When I watched them I felt resentment. And when I tried to participate I felt not excited. I asked my wife what I could do she told me 'anything the guy does'. So next time we did it I decided to take my revenge and then call the whole thing quits.

I set up my phone so that it recorded my wife's face and that guys groin. Then I let my wife take him in her mouth and I took her from behind.

As my wife pleased the guy orally I grabbed her head and pushed her onto him until she was out of air. She choked but she did not ask me to stop. The guy seemed to like it very much.

My wife never throats and the guy probably did not know that. So I kept on pushing her head a couple of times and when I saw he was nearing ** I pulled out and went into her smaller hole. I never did before, but the guy did this on her video. And she said 'whatever he does'.

Now my wife tried to back out, but she could not. And then I grabbed her face and held her mouth open and pushed her forward so hard that all his d--- went all the way into her wide open throat. The guy exploded immediately and I held her head there for a long moment. My d--- was in her a-- and his d--- was in her throat. And she had nowhere to go. And the guy kept it inside his throat until he was empty.

When I let her go she grasped for air - but it was too late - all his load went into her stomach. She went mad and started beating me and crying obscene things. Then she started hitting the guy who understood nothing. Then she run too the toilet and locked herself there. I think she puked.

I said goodbye to the guy and I went.

I sometimes play back the video again and watch it. I like to see the moment her eyes go out of orbit and she is reduced to the animal she is. She reduced my to a **, I reduced her to an animal begging for air, with her stomach full of **.

I do not even hate myself for what I did. It was not me who betrayed and broke the promises. She did what she did and I did what I did. To find a lover and then ask me to become her living ** toy. How disgusting.

Not looking for another right now. Will live and see if I meet someone who does not get cheap after 7 years.
