At just thirty seven I found myself at the doctors with a potentially serious health problem. The doctor suggested that I needed to loose probably two stone in weight if I didn't want the condition getting worse and to do more exercise. There was light at the end of the tunnel when she offered me a ticket to take to my nearest Slimming World Club for twelve free sessions. That night in the pub my mates ribbed me at going to what they called fat club. None the less I decided to go, and was glad that I did.

The first session was a bit daunting where the woman running the session went through how the process to loose weight for them works. It seemed simple enough, and then after sitting through the rest of a session with probably forty women and just one other man, I was weighed and given lots of literature and my own book. I later read a fair bit of the bumph.

I tried to keep as close to the plan as possible and at the next session one of the women struck up a conversation with me. Kaylee was a pretty short woman in her thirties at a guess. She was what I would describe as cuddly rather than fat. She was telling me how hard it was for her to loose weight as her husband and kids didn't help her and she found it an uphill struggle. I was shocked at the weigh in that I had already lost seven pounds. Kaylee told me that was normal in the first few weeks but, it would get harder and slow down as I went further towards my target.

I found myself drawn towards Kaylee even though I now knew she was married with kids. The fact that when she sat on an average chair she couldn't reach the floor with her feet so she sat cross legged, which with her pixie hair cut and cute face just reminded me more of a pixie or elf. After the session I made my way home. Later in bed I found myself dreaming and fantasizing about her and eventually wanking myself off.

The next week, I had again had a good weight loss of six pounds, and found that I had won slimmer of the week. Again chatting with Kaylee she had gained two pounds. Most of the people there wore pretty skimpy clothes to reduce their weight when they got weighed. Then they would redress with much heavier and weighty clothes to keep warm. I enjoyed seeing some of the women half dressed. Although most were older than my preference. Kaylee had on shorts and a plunging front Tee Shirt, and clearly by the way they moved, her tits were not restrained in a bra. I was pretty sure she saw me looking down her top at her plump titties. She again extolled how hard it was for her and I suggested that we exercised together and discussed foods.

Kaylee said that she would like that, but it would have to be at her home as she would need to be at home because of the kids, and her husband would generally be at the pub or working. I quickly agreed to her request and found myself at her house two nights later. She was again dressed in shorts and a Tee Shirt but she also had on what I guessed was a sports bra. Her husband was at work and the kids were in bed. I showed her various exercises and she opted for some to work on her legs, thighs and stomach saying that she didn't need a bigger bust so upper exercises weren't needed. I joked that I could attest to that as they were prominent through the Tee Shirt. Kaylee and I got down on the carpet and in the all four position stretched a leg backwards and then returned to the on all fours position. Ten of those and then ten with the other leg.

Sitting on Kaylee's legs I had her do ten sit ups and then she sat on mine while I did my ten. Then we did ten standing and stretching down to touch our toes. I could feel my cock twitch as I had ten good glances at her tits. In all we did fifteen different exercises. Kaylee looked hot and sweaty and good enough to eat. It was a tough thing to walk away and go home. Later in bed I wanked myself visualizing those tits and her arse as we exercised.

The following week Kaylee had lost four pounds and quickly asked me to exercise with her some more. I had also done well and lost six more pounds and was over half way to my target. Two nights later when I arrived to exercise with Kaylee her husband was still there and watched for a few minutes as we started the routine that we had previously done. He joked that he didn't want his sexy little cherub loosing too much weight. Then he buggered off down the pub. I could see what Kaylee had said about not having any support. This time due to toys on the floor I was behind Kaylee as she stretched a leg backwards and I could see up the crutch of her shorts to a bush of black hairs. My cock again twitched.

Then as we bent forward she obviously wasn't wearing her sports bra as her tits dangled and I had a great view down the valley between her tits and again my cock twitched. I was pretty sure that she had deliberately caused my cock to stir. By the fifth or sixth exercise I couldn't help myself and gave her sexy arse a playful slap. Kaylee yelped but held her arse still for a second slap. It wasn't long before our exercise turned into sexercise. Kaylee, once naked, knelt on the floor and had her torso on the seat of the sofa while I got in behind her and slipped my already hard cock into Kaylee's hot wet pussy. Her pussy lips really hugged my cock as I lunged in and out.

We were soon groaning as I pumped my cum deep into her pussy. After a short rest we both dressed and tried to pretend that we were still exercising. It wasn't long before I had her tits out again and then removing her shorts. This time I picked her up and lowered her onto my stiff cock as I stood and jigged her up and down on my cock. Kaylee was soon moaning and groaning as I fucked her on my cock. Her short legs tried to lock around my back but weren't long enough. It wasn't long before we were both coming again. We quickly dressed again and tried to finish our exercises.

We had just finished and dressed when Kaylee's husband came in and after seeing we were both hot and sweaty, told Kaylee that he had been called into work. He grabbed some keys and a jacket and was gone again. It was barely fifteen minutes later when I fucked Kaylee for a third time on the sofa. First on her back and then in the doggy position. I drove home exhausted while Kaylee went off to take a bath.

That week Kaylee lost more than I had at five and a half pounds and I lost just five. Kaylee was the slimmer of the week. A title she told me she had never managed before. Again over the next few weeks I went round to Kaylee's and during exercises I again fucked her several times. We were both still loosing weight and it was visibly possible to see that Kaylee had lost weight and several of the other women asked Kaylee how she had turned her weight problem around. Kaylee told them that it was a mixture of exercise and the program. One of Kaylee's friends looked straight at me and said that she could do with some of that exercise to Kaylee. I shuddered as Joy was fat, and I do mean fat and I didn't fancy her at all.

I later discovered that Kaylee had told her that I was training with her. Her friend, Joy, must have guessed what sort of exercising we were doing. I was surprised when Kaylee's husband let me into their house, and before going down the pub said, "Keep doing what your doing with Kaylee. It's making her tits look even bigger. He wasn't wrong, as she lost weight around her tummy it had made her tits look bigger. I should know. I was playing with them every week. This week was no exception and we again weighed in lighter than the previous week. It was during that session of fat club that one of the other women, a woman in her late forties came up to me and asked if I would do some training with her and look at her weekly menu.

Bev was quite an attractive woman, and I soon discovered that she lived on her own. I was soon giving two of the groups ladies regular sexercises. Bev wasn't particularly over weight she just went to try to maintain her weight. By the time I had fucked her three times and spent the night in her bed, I knew I was now in fat club for the long haul. By week ten I had hit my target and Kaylee was well past half way to her target. Bev was just enjoying her extra curricular activities and keeping her weight stable.

Bev's mate a married lady, Ruth, asked for some help and made it obvious what kind of help she wanted. She said that Wednesday nights were good for her. That was my swimming night and I couldn't move that so she said for me to go around on Friday. I was shocked that there was no pretense about what this married lady wanted as she opened the door to me in a dressing gown that had dropped to the floor before we even got to her lounge. She was totally naked. She told me that she had no time to waste as her husband would be home in a little over two hours time.

After a short blow job I was soon banging this forty one year old married lady. I managed to get hard enough and quick enough to fuck her a second time draped across the dining table. By the end of the twelve weeks I had lost two stone six and a half pounds and was still loosing weight. Well you'd be loosing weight if you were eating well and shagging three women, two of which were married, plus swimming once a week.

My doctor was pleased with my weight and that my issues had passed. My doctor told me to keep it up. If only she knew who I was keeping it up with. I had other women asking to join my exercise club and I had to turn them away. Kaylee was doing well and she was eating better things and with the shagging I was giving her, and the fact that her husband was paying her more attention and fucking her far more often, she was just a few pound short of her target. I was due to see her again in a few days time.

Then I bumped into her husband as he staggered out the pub. He had definitely had a few too many and when he called out to me that he needed to talk to me. I went over to him and he told me outright that he knew I was fucking his wife. I was expecting a drunk husband swinging fists. Instead he told me that it was doing her the world of good as she looked better with the weight loss and she was much sexier in bed. He told me that as long as his kids don't get to seeing us together he was happy for me to continue fucking her. He even said that he didn't mind if he walked in on us at it and not to stop if he did.

That week I gave Kaylee and extra good shagging and she asked what had got me so worked up. I told her of the conversation I had with her husband. She was a bit annoyed with him but it didn't stop her letting me fuck her again doggy style on the sofa. This all went on for almost four years before the virus struck and we were all soon in lockdown. Being single, I moved in with Bev, and even now as things have improved I still sleep with her several nights of the week.

During the lockdowns both Kaylee and Ruth had put on weight. I am now shagging both of them again and sexercising with them to get them back in shape. Kaylee's husband did walk in on us one evening and just stood watching for a while before going out again. Ruth's husband has no idea what his wife is getting up to, to loose weight.

As for me I have managed to maintain my weight, but can see that many people have not fared so well in the lockdowns. Shame I don't have the stamina or time to help more of them out.
