My wife Karen was sleeping at Susan and John's place. I did not sleep all night, I realized how excited I was about John's proposal. 

I hoped John was right: That John and his "contacts" could make Karen a "bad girl". Convert my shy wife into a slut. The idea of Karen being a bad girl behind my back, and John sharing details with me, really turned me on.  

Karen arrived at 11 AM from John and Susan's house. The first thing she did was to give me a big, wet kiss! "I missed you!" she said. "let's go upstairs and make love". 

We were soon naked in the bed. "Is this your new way of missing me? keep missing me!" I said jokingly. Karen was soaking wet, really excited, wilder and louder than usual. She had a shaking orgasm, faster than I can remember. I also came fast, all while my mind was racing: What had Karen been up to, what excites her so much??

Later during lunch, Karen told me she had a really nice visit to John and Susan´s house. Susan was very pleasant and she presented Karen to some friends. Also, Susan was a great photographer and this morning she had taken some stunning portraits of Karen. 

Karen showed me the portraits on the phone and they were really good. I couldn't stop thinking about what other photos Susan had been taken of Karen?

"by the way, John gave me this package for you, some work stuff she said". I had no idea what it could be. When I opened the package in my home office, it was a phone. I turned on the phone, but it had a passcode. I was sure this was a part of John's secret game.

Later the same evening John messaged me: "Check Susan's new Whatsapp group "Potential slut Beth". Your wife has a slut name now". "Beth did not have my cock last night, only Susan´s pussy. A perfect, slow start. The men in the group love slow starters. Married, faithful, no slut experience, Beth is perfect. Check out the group: Phone code = 696969".

I excused myself and went to the bathroom with my new phone. He was right, I was a member of the Whatsapp group "Potential slut Beth". Together with other 19 men and "MAMA". 

It did not take rocket science to guess who MAMA was. My username was Brian!!

As soon as I entered the group, MAMA wrote: "Please all welcome Brian. In this group he is Cuckold " I answered the polite welcome messages, such as "welcome Cuckold, thank you for joining us" and "Welcome Cuckold, you must be as excited as we are".

I scrolled up to the first message in the group, which was from MAMA, the same morning: "Hi all, guess who has been eating married pussy last night? A real stunner, a screamer!". 

After several messages like "great!!", "Lovely" and "tell more", MAMA wrote: 

"I named her Beth, It was her first female sex last night. John wanted to fuck her, but I saved her first extramarital cock for you. Lets have herself sharing that one day soon." 

"As a slut Beth is 100% virgin. Slow starter, but quick learner, she loved her photo shoot with me this morning. She promised to share the first picture in her own group tonight".

I noticed another group on my Whatsapp: "Beautiful Beth". Same 19 male members, same MAMA ... and a "Beth". The group had no messages. Just the "joining the group" notices. So this was my wife's group. 19 men and Susan waiting for her first post.

I checked "Beth"´s phone number in the group, the number was not my wife´s. I realized Karen was hiding a new phone, just like me!

I returned to Karen, but it was hard for me to concentrate on our conversation. Was Karen going to post her first picture as Beth tonight? Sharing her married body with 19 men? It was so unreal, maybe it was me overreacting, but I felt Karen was nervous also.

Karen received a phone call from Susan. "just some girl gossip, I'll talk to her in the kitchen," said Karen. I knew Karen was on the phone with the woman who had been eating her pussy the night before, her photographer, her Whatsapp group administrator. They talked for half an hour. Then I could hear Karen hang up and go upstairs.

I quickly found my new phone again and entered her Whatsapp group. I could see Susan had posted, while she had been on the phone with Karen:

MAMA: "Welcome to Beth´s adventure!. Beth has asked me to have all members confirm, agree and respect the rules: 1. NO sharing outside the group,  2. NEVER contact Beth outside the group, 3. ONLY Beth is allowed to post images and videos with Beth, 4. When asked to delete all material, you will do so". 

There was already a list of "I agree" messages. I quickly sent my "I agree" also. Then came Beth's first message: "Welcome in my group. I am both very excited and nervous. Be kind to me..." . Messages from members praised her initiative, promised to be kind etc., and then ... Beth posted her first picture! WOW!

My wife was on all 4. She was wearing red high heels, red stockings and a red bra, nothing else. Open legs. The picture was taken from behind. She was partly covering her pussy with one hand, her long hair beautifully on her back . Susan was really a good photographer and my wife was now Beth. The slut.

The screen was soon filled with respectful and encouraging messages, her first post was definitely a success! 

I could hear Karen coming so I quickly put the phone away. She came into the room and said "I have a special request: I want you to fuck me!". I said "Sorry?". She said "Please don't ask any questions, I will be waiting for you in the living room in 5 minutes", she turned around and left.

I could not believe my luck. My wife had just shared the most sexy picture I have ever seen of her, with 19 men, complete strangers. And now she wanted me to fuck her.

When I walked into the living room a few minutes later, my wife was on the floor, on all 4. Wearing red high heels, red stockings and a red bra. Exactly as in the picture she had just shared!! Covering her pussy the very same way with one hand. She was breathing heavily. "Please take me hard today, as if I had been a bad girl".

I took position behind her, removed her hand and inserted two fingers in her pussy. A moan left her throat. Her pussy was open and dripping wet. She was Beth now. I was rock hard and entered her fully in one single stroke. She let out a scream and her legs started shaking. Her fingers were on her clit, her pussy in contractions around my cock, and she was screaming... 

We spent the next hour fucking. Amazing sex. 

20 men had just witnessed the initiation of my wife´s new lifestyle. I was the first of the 20 to fuck the slut Beth. But not the last. Little did I know that the other members of the group were very generous gentlemen. Little did I know how my wife soon learned to combine their generosity with sexual adventures.
