Husband:

My wife has been working in her new role as Manager of Customer Satisfaction for a while now. She is earning more money than I am, as she gets sign-on bonuses for convincing new customers to use her firm. She works hard all day, often with as many as four customer meetings. There is no time for paperwork as it takes her some time to recover, so she works at home on a Wednesday to catch up with all that.

She also has celebratory drinks from time to time after work, especially when the account is 'big'. On the other hand, she has no time for the gym and is worried that she might be getting out of shape. I suggested that the gym we both use has two personal trainers. With her lack of time and more money, using one of them on a Wednesday lunchtime might solve the problem for her. She was very happy with my suggestion and thanked me.

I said that I wasn't worried about any potential impropriety because I've seen the trainers working out with women customers, and they always seem so professional. My wife tells me that she has done a deal with one of the personal trainers at the gym. I've seen him around the gym, and women are always chatting him up. I have a little fantasy that perhaps my prudish wife might take on more than exercise.

She said she wanted a tailored workout that would help her build up the muscles she needed for her meetings. The guy has sorted out a routine that covers most of the muscle groups and ran my wife through it. She told me that the exercises were variations of basics like squat thrusts, push-ups, and the like. There was also a set of stretches to finish off with, plus a protein shake to finish. I wasn't aware the gym had a cafe, so I wondered about that last bit.

Wife:

I went to the gym to work out for myself, following the suggestion of my husband to use their personal trainer. I was hoping that it would work out because on a visit to the gym last weekend with my husband, a woman in the changing room was talking about Karl. She had gone for a drink with him, ending up at his house. Although it was just a one-off, she was letting everyone know that the sex was mind-blowing and he was hung like a horse.

I managed to get a trial session the following Wednesday and made sure I purchased some new gym kit online. My normal stuff was fine for a visit with my husband, but to attract a trainer, I needed something more. It was pretty much the same as my clothes at work, skimpy and thin, exposing as much flesh as possible. I checked myself out in the mirror, and there was a nice bit of cameltoe, and my erect nipples could be seen.

Unfortunately, there was a yoga class in the private room, so we did the workout on the stretch mats. I had to wear my 'normal' gym kit. Despite the lack of privacy, Karl managed to stroke my ego by cupping my ass a couple of times under the pretext of getting me in the 'right shape'. There were a couple of other inappropriate moments as well, before I finished up a sweaty lump that was so horny I needed to rub myself off in the shower.

He had another client, so I dropped back to the gym after Karl's last session, well before my husband got home. I wore something a little more sexy, and we had a productive chat. Karl had recently taken on an apprentice, so he could increase his income. He had not realised that his apprentice would take so long to train up to the standard that his current customers needed. I agreed that both of them could be at my sessions.

Husband:

My wife discussed her trial with Karl the trainer later that evening. She went through the basics and told me that she was happy to start with him the following week. She went on to say that the clever bit was that instead of the full range of movement, she made minor, intense actions. When I asked her for clarification, she said the movements were around eight or so inches at a time. I thought that was a little odd, but I went with her explanation.

She also explained that she did get a bit of a sweat on, so she was glad she decided to wear her gym kit. What she was wearing when they met up for the induction was fine to do the workout in. So she said it was all able to be fitted into her lunch hour. An intense workout, but not that dissimilar to stuff she was doing every day now at the office. I was a little bit confused, as the trip to or from the gym was at least ten minutes.

She was talking about an hour session in an hour, with two sets of ten minutes travel and a shower afterwards. When my wife tells me stuff that confuses me, I don't like to question her about it. She says she has signed up for the workout at a very low rate. Using the skills in negotiation she has picked up at work, she worked out something that was agreeable for all of them. I was hoping for some sex as she was glowing, but that soon turned into a glower when I suggested it.

I hoped that the nightmare that was our last sexual encounter, when I came in seconds, had been forgotten. Not a chance, so I sloped off to the computer to read some stories about sex at the gym to go with the sex at the office ones I had been reading recently. My fantasies of my wife moved from sex with her boss to sex with Karl. Although I knew that neither was likely. My wife was a bit of a prude, and her session took place in full public view.

Wife:

I took a lot of care in that first session, the following Wednesday. After my husband left, I had a shower and shaved off all of my bodily hair, making sure my pussy was well oiled. I might have brought myself off a couple of times to try and take the edge off my horny state, but it didn't really work. I knew I needed to get paperwork done, so I worked at double pace to get everything finished before they arrived at two.

I changed into the gym kit I had spent hours agonising over. I purchased it all from the internet, as no shop would stock anything so slutty. The crop 'sports bra' had a scooped-out middle, exposing the inside of my breasts, and had mesh panels for most of the rest. The booty shorts to match were thin and moulded to me like a second skin. It too had mesh panels over the hips, and the pair of items left little to the imagination.

Both trainers turned up, with Karl just staying to run through the routine with his apprentice. He then left, as the apprentice would jog back to the gym. I mentioned that I was looking forward to the 'Sexercise' routine he had put together. I told both of them not to worry about touching and moving my body if it wasn't in the right shape for the maximum effect. Karl looked disappointed when he left. The apprentice was young, toned, and, as I found out, also hung like a horse.

We lost our clothes quickly, but although we had a great sexual encounter, it was still energetic for me. I had to do squats, up and down on his long cock to start, and it went on with more of the same. The best bit was the stretching at the end. As well as contorting my body into odd shapes, which extended my muscles, his cock was stretching parts of my cervix that had rarely been touched. The session was long enough to satisfy me, but only just.

I made sure the apprentice knew that it would be perfectly okay if Karl stayed to fully supervise the session the next week. The thought of two long, thick cocks giving me a thorough workout each Wednesday was enough to balance off the weekends where my pussy got too much rest.
