My quest to get back in shape led me to join my local gym. I grew to love the feel of using the various machines to pump up my muscles and get the burn of a good work out.
It also led to me making a very good friend at the gym, Susan. We must have had similar schedules because we were often there at the same time. She was the bold one and started a conversation with me while waiting for me to finish on the leg press machine.
Soon we were helping each other push ourselves, keeping the boredom away that was the downfall of most exercisers. She was a very attractive woman, about 10 years older than I was, and unfortunately married. But there was an undeniable spark of sexual chemistry between us.
I found myself fantasizing about her while watching her toned body strain under the weight of one machine or another, imagining her body naked while she continued her workout.
I know she caught me looking at her several times with an erection. Her smug smile made me feel like a little kid who got caught stealing cookies.
We spotted each other on free weight workouts. I loved being able to occasionally put my hands on her body as I helped her do her final reps, or if she struggled too much.
And when she did the same for me, I often got hard thinking about her touching me more intimately.
It got so that I was having very complicated erotic dreams about her.
In some she was a sexy earth mother type who fucked me in some outdoor paradise.
In others she was younger and innocent, and I corrupted her, violating her in every one of her openings.
These dreams would wake me in the night, and I would have to stroke myself furiously, spurting hard, to get myself back to sleep.
I flirted with her more overtly, but to my dismay, while she was warm and attentive, she really didn't return my sexual signals. Susan suggested I get in with a trainer in order to push to the next level. She had done that when she started at the gym and loved it. In fact, she offered to speak to the person who trained her.
Susan got back to me the next day saying the trainer had one opening for last thing that evening if I wanted it.
I agreed and asked Susan if she would join us. She laughed and said she wouldn't miss it. I arrived at the gym and waited for the trainer. I watched Susan walk up with a very pretty younger woman and she introduced me to my new trainer!
I admitted to being very surprised at the trainer being a woman, but when Susan asked if it were a problem, I of course said no.
Karen, the trainer got me started with warm ups right away, watching my technique while she and Susan chatted.
We moved on to some of the various machines, I became very aware that Karen didn't hesitate to touch my body often while correcting any 'break in form' while using the machines.
I cursed the fact that I wasn't wearing my jock strap to help harness my slowly hardening cock, and having Susan there watching me the whole time didn't help one bit.
The Abs machine was my undoing. I lay flat on my back, with my skimpy shorts and a prominent lump in the front, straining to push the weight up with my stomach muscles.
Susan was on one side of the machine and Karen was on the other. Both were staring hungrily at my erection.
I could feel all control slipping away. Their eyes burned my skin, but I was covered in goose bumps.
Karen snapped me to attention, barking out "Use your abdominals, not your leg muscles Carl!" She pressed her tiny hand against my stomach, so near my throbbing meat I shuddered. "Susan, we need to double team him, you focus him in his 6 pack while I pull back on his arms." Sarah commanded.
I felt naked and aroused being stretched out by two sexy women, and the head of my throbbing cock pushed against my waistband.
I did another rep, but my focus was shot.
Susan noticed my cock move under the thin cloth. She called over to Karen and asked her to come help, saying she thought I had a serious problem.
"Look at this knot; don't you think it dangerous to exercise like this?" Susan asked Karen.
I looked on horrified at the giggling women as they laid their hands on my tented gym shorts, feeling the length and thickness of my cock pulsating in their grip. Even embarrassed I was powerfully aroused.
Karen thought that a massage might help the situation, and after a quick look around, deftly slid my shorts and boxers down to my knees, letting my boner pop up in their faces.
"So this is what was causing the problem." Susan said. "I have been noticing this for a week, and now we get to the 'root' of the problem."
Karen wrapped her hand around the shaft and gave me a quick stroke or three. It felt too good to stop her, and when Susan started tweaking my nipples I let out a moan and closed my eyes in ecstasy.
I couldn't believe these two sexy women were doing this to me in such a public place.
But the feelings were too intense to resist. Karen called out to the other female trainer who was exercising across the gym, asking her to come over and help her out with a client.
My eyes followed this very hot, dark haired girl, with a killer body, walk across the gym floor, with her eyes getting bigger and bigger as she saw my exposed condition.
Karen was still applying feather touches to my erection as the other trainer stood by them with a huge smile on her face.
"I have a new theory about getting men to be motivated in the gym. I think they all should exercise naked! That way we can see who is really into it and who needs more motivation. Now here we have a prime example of a motivated male. Carl, I want you to give me 10 reps on this machine, and be sure to use your abs, not just your legs OK? And we can all see what muscles you are using, so concentrate!"
Sarah, the other smoldering hot trainer, stood next to me. "I can sure see the wisdom of your plan Karen, and I am anxious to see the rest of his workout," she laughed
