My girlfriend and I have been going to the gym together since we started going out three months ago. After going to the gym we very often had sex and Judy was always more enthusiastic than usual. I had not thought much about it until she said that she had an embarrassing story to tell me.
She told me that when she first joined she had arranged to have a session with a personal trainer. The personal trainer she had a session with was an attractive fit young female trainer. The session had gone well and the trainer said they would finish with some sit ups that involved the trainer holding Judy's feet. They agreed that three sets of forty would be completed.
During the first set when Judy had completed about twenty she became aware of being deeply sexually excited centered around her stomach. She didn't want to stop as she would have to explain why. As the set went on the arousal threatened to erupt into an orgasm but Judy managed to contain it by trying to use less effort.
Judy said the trainer seemed to recognize her arousal and asked her if she was okay to carry on. After the first set Judy was flushed and breathing heavily. The trainer told Judy to rest before the second set. While she lay on her back the trainer massaged both sides of Judy's lower stomach saying that she needed to relax. This only made things worse as Judy started to get moist between her legs.
