This is an ongoing story so I’ll give you updates as things develop. I have always liked the idea of fucking someone else’s wife or partner, but I had not had the oppurtunity until recently. I am the member of a gym and over the last year more and more women have joined in with the classes. Like most red blooded men, I have noticed a few that I had fantasied about having sex with. One of these was Sam. I would describe Sam as 5’6 tall, medium build, aged about 35, short hair and with big breasts. She was quiet in the classes and usually did not wear much make up as we all usually got really hot and sweaty. I would have said she was an average housewife who did not make the best of herself after being married for sometime, but under the tight Lycra her body looked very good. About 6 months ago, the gym organised a weekend away in Manchester. This was to visit the city, enable members to get to know each other better and to attend a few different taster session classes at a gym linked to ours. We travelled together in a mini bus and arrived at our hotel about 11am and were allocated rooms. I was sharing with another male member and the ladies were all paired with their friends or other female members. Whilst we were there, we set up a what’s app group so we could arrange to meet up later that day after people had been off to explore the city. About 9pm, most of the male members had met up and started drinking. The what’s app group was active with the ladies asking where we were going and what the plans were for the evening. About 10pm, the ladies arrived and that’s when I really noticed Sam. She arrived with her make up done, wearing a tight top which showed off her lovely big tits, a skirt and a pair of black boots. She was more talkative than I had seen her before and as the night went on, she drank more and more. Like most men, we talked about who they would like to have sex with and we wondered if the women were having the same conversation. After walking around a few pubs and bars, we ended up at a bar with two large tables. The men sat on one and the women sat together. I was sat at the end of our table, close to the women. After drinking for sometime, their conversation turned to sex. I listened intently at what they said, talking about what they liked and what they didn’t. They discussed oral, who would swallow, what positions they liked and if any of them had tried anal. Sam did not really join in and she hadn’t striked me as the sort of woman that was sexually liberated and I imagined was quite straight. This was confirmed when she said she had never tried many positions or anal and never would as she thought it was wrong. At the end of the evening we waited to share taxis back to our hotel. I ended up with Sam, Liz and Pete who I was sharing with. The taxi came and Sam got in. It was clear she was really drunk and when we arrived at the hotel, I helped Liz take Sam to their room as she could barely walk and sat her on bed before I left. The following morning, Sam was not at breakfast and missed the classes as she stayed in her room as she was feeling sorry for herself. About 6pm, I received a what’s app message to say that she was embarrassed and could not remember most of the evening. She said she had drunk far to much as she didn’t get out much and liked being away from her husband and children for a few nights. I told her not to worry, but she was very apologetic and thanked me for seeing her to her room safely. Who knew that a simple what’s app message could be the start of my fling with Sam and how I sexually educated her from being a quiet, straight housewife into my SAM (Submissive Anal Milf).
