I finally talked my GF into having sex with another guy. She picked the guy, a friend she has known for about 3 years. . She told me they had talked and she would be going to his place this past Thursday. I drove her to a coffee shop near his apt. I left but didn't actually leave, I parked at the other end of the lot with a sight on the coffee shop. after about 15 mins I see them walking across the lot, hand in hand. I drove home and waited for her phone call. about 3 hrs later the call came through. Jo said they had sex two time and he came in her both times. I asked her if she was going to head over to her GF's for the night where she had planned on staying. She said that john had asked if she would stay at his place. She said she though why not. She then said " you talked me into this so you had better get used to it, because it has started it is going to happen " I asked her to call me at work on Friday. Jo finally called at noon on Friday. I asked her what happened and she said they had sex two more times Friday morning. I went to picker up Friday after work and we went home. Shortly after we got home I got her into bed and cleaned her out, then topped her up. Saturday afternoon we went out to do some shopping Jo's phone goes off and its john. They texted for a few minutes. I asked her what John wanted , Jo says well John was wondering if I wanted to cum to his apt as his daughter was going to be away. I asked her what she wanted to do. Jo's response was " like I said ,you want me to do this , so I am going to go again" Joe said she would call me at 7:30 am and I could pick her up around 8am. Jo called exactly at the time she said. I asked her if she had fun, she said OH Ya I sure did. In 3 days she fucked him 6 times and me twice. That's my girl.
