I had become so overweight and lazy, affecting my health and our sex life, so I decided to join the local gym.

My wife was at work and I had a few hours on my hands before I had to go to work, so I drove down to the local gym.

The problem is my hours are so messed up I don't really have time to go. I work twelve-hour night shifts driving HGVs and this has caused me to pile on quite a few kilos. I am in my early sixties, I am not so tall so I look much fatter than I really am.

I had become very lazy, my routine was working, bed, sleep, working, bed, sleep, five days a week. And at weekends it was beer, wine, and lots of bad food.

At the gym, I was met by one of the partners who showed me around what was a small friendly privately owned concern. I was impressed enough to sign up and arrange a meeting the following day with a personal trainer.

The following day I met one of the trainers Tom, he gave me a few exercises and worked out a program for me. The training also included nutritional advice and a plan to lose weight and gain muscle.

I started going to the gym daily as soon as I woke up and before I went to work. I started going seven days a week, mainly doing cardio work and gradually included weight training.

This went on for six months by which time I had lost twenty-five kilos in weight and my fitness was improving week by week. I saw my personal trainer twice a week and became good friends with both him and his very pretty and incredibly fit girlfriend.

At weekends I have been quite often the only person in the gym as I train late in the afternoon. One of the trainers is usually about and ready to lock up as soon as I finish, quite often this is Tom's girlfriend Suzy.

Suzy is tiny, barely 5'2 really slim with small but pert tits that have really stubby erect nipples. Suzy is twenty-two a perfect blonde and incredibly fit and beautiful, her best feature is her tight firm arse.

On most Sundays, Suzy and I train together, have a good chat, and then grab a coffee before locking up and heading home.

This Sunday I arrived at the gym at two o'clock, just as most of the regular members were heading home. Tom and Suzy were both present as were about three other members working out. The gym closes at four pm so I knew I had a couple of hours to train and grab a shower before I had to leave.

Over the next hour, the other members left as did Tom, Suzy locked the door at three thirty so no one could enter and start a workout.

I was completing my workout using the indoor cycle, which is well-positioned in the gym, allowing me to watch Suzy working on the mats and floor.

Suzy always wore similar gym wear, a baggy vest top over a sports bra or boob tube and tight Lycra shorts. Suzy always looked so sexy and hot even whilst working out and perspiring.

On this occasion, I was wearing tight cycling shorts with no underwear and a basic T-shirt. The shorts showed off my considerable bulge really well, and after watching Suzy for twenty minutes my bulge was very clear to see.

Suzy called time just before four pm, we both retired to the kitchen and shared a coffee whilst chatting about our workouts, then we both went to the changing rooms to shower.

I completed my shower and was drying off in the changing area completely naked when the door swung open and in walked Suzy, as she entered she said, "Are you ready then?"

I had just dropped my towel on the floor and was about to pick up my boxers when Suzy walked in, "Whoa, give me a minute." I said, trying to cover my predicament.

Suzy was now dressed in a plain white T-shirt and a very short denim skirt and nice heels, she showed off her perfectly toned, tanned legs, something I had not really noticed previously.

Suzy said, "Oh, I am sorry." Suzy was standing just a few feet away, staring at my swelling cock. I had removed my hands in an effort to grab my boxers so she had a clear unobstructed view of my cock.

Suzy said, "Nice cock, old man."

Suzy turned round and left the room much to my disappointment, and said, "Sorry."

When I met Suzy in the reception it was as though nothing had happened, we said our goodbyes locked up, and went our separate ways.

The following week was much the same, Suzy looked hot in her gym wear. I also wore much the same as the previous week, so much bulge was on show again to anyone who wanted a thrill.

At three-thirty, Suzy locked the doors again, leaving us alone to train and complete our workouts. As was the previous week Suzy continued to train right in front of the area I was using, this gave me a semi-erection that my shorts were struggling to contain.

Just before four pm, Suzy called time, we once again shared a chat and a drink then went off to shower.

I had just started to soap my aching limbs when the shower door slid open, outside stood Suzy wrapped in a huge white fluffy beach towel. "Can I join you?" Said, Suzy.

"If you really want to, of course, you can," I replied.

Suzy dropped her towel and joined me, her body was amazing, her tits although quite small were so pert, and her nipples were so hard and dark in colour.

I was stunned and amazed not really knowing what the hell I should do. Suzy knew what she wanted, she took my raising cock in her hands and added some shower gel. Suzy then washed my cock and balls, helping my cock rise to a full erection.

I added shower gel to my hands and did the same to her perfect pert tits. Soaping and washing them, I gave her huge stubby nipples plenty of attention.

Suzy dropped to her knees and wrapped her tiny lips around my swollen cock, she was unable to take much due to the size of my cock. Suzy rubbed my cock and she gave me an amazing blowjob, I only lasted a few minutes before I filled her mouth with stream after stream of hot sticky semen.

Suzy swallowed as much as she could, the rest I sprayed over her perfect tits.

Suzy did not allow me to touch her when I tried, she washed herself down, gave my cock a nice rub, and left the shower. As she left, she said, "Same again next week, next time though I get some action".

Minutes later we met in reception as if nothing had happened, then locked up and went home.

The next installment is due really soon, fingers are crossed Suzy keeps to her promise.
