Last year we met a tall black gentleman at a bar. We learned that he had masters in health and physical education. He did personal training of couples. He was caressing her ass while he explained his services. He asked me to get everyone another drink. The bar was very crowded. As I made by way back with the drinks, I saw them groping each other. When they saw me, he removed his hand from under her top and she pulled her hand away from his crotch. We talked for a while and he gave us his card and left. On the way home, I asked what happened. She said when someone bumped me and I fell forward against him. He put his hand under my loose sweater and was feeling my breast. He placed my hand on his cock. She said he was huge. She said he told her his training was very complete but she said it wasn't something she was interested in doing. Recently, she has had some health issues and it has been suggested that she should get a personal trainer. We are at our winter home in Florida and are really not familiar with all the services in the area. She suggested maybe he was a candidate. I found his card and contacted him. He said he remembered us and he would be willing to be her trainer. she would have to agree to his terms including diet and his program. I asked him rates. He told me it would be a fee per trip. When I said that might be unaffordable, he said there may be ways to get a discount. He said he would meet with her and explain his program. I told him if she knew the cost, she would not agree. He said payment would be between me and him. He would meet with me after he met with her. Actual fees would depend upon what agreement was reached with her and then what I would agree with separately. We have been swingers for years. She has had sex with several black guys. She has one favorite that she sees occasionally alone but we have never been in an arrangement like this. I have a queasy feeling about entering into this agreement. He says it has to be at least three times a week.
