PART ONE
I work for a marketing company in one of the large buildings in the centre of London. The job was well-paid and the company liked to reward its staff for the hard work we all put in. That was why in the building, there wasn't just office space, but also a couple of restaurants, a barbers and a state of the art gym with a swimming pool and sauna/Jacuzzi.
I work hard and so would usually end my day by having a swim in the company pool. At 28 years old, I liked to think I was a good looking guy. I have messy brown hair that usually came down to my hazel eyes while my body was slim but still toned thanks to all the hours I had trained as a swimmer at university, and the fact I had kept that swimming regime up. While I had a six pack I was proud of, I still wanted to bulk myself up, and get some muscular arms and more defined legs. That was why I decided I wanted to start working out at the gym and doing more weight training to get myself the ripped body I wanted.
I decided I needed a bit of help with this, and that is where I had picked out one of my colleagues Dean to help me out. Dean was in his late 30s, but worked out at the gym for a couple of hours every day, and so looked really good. He had huge biceps, and his legs looked like they could crush a walnut. I'd heard he used to play rugby at university, but he had to give it up when he suffered an injury, but had kept up with the gym regime so that was why he was so built.
That night, I was doing my normal routine of some laps at the pool when I spied Dean lifting weights at the gym. I decided now was the time to go and ask him for help. I climbed out of the pool and dried myself off with my towel. I walked over to him in just my Speedos. Like I said, I had a good body and wasn't afraid to show it off. I like to wear really small red Speedos as I look really hot in them. They were probably not appropriate for wearing at the place I worked, but I felt good when I saw myself in them so didn't see any harm. The changing rooms were located on the other side of the gym so I had to pass through it to get changed. On my way, I stopped off at the weight section where Dean was pumping iron.
"Hey Dean, how's things?" I asked.
He looked up at me with sweating pouring down his face. His black Lycra top was clinging to his muscular frame due to the sweat. I could have sworn he gave me the once over, and my cock jumped in my tight Speedos when he did. I'm sure he must have noticed. He smiled. "Hey Mike, I'm good thanks, how's you?"
"Great. Always feel good after a swim. Look, I was wondering if you could help me?"
"Sure thing" he replied.
"I'm really keen on bulking myself up, and you look like you know your way around the gym equipment, I was wondering if you would be happy to help me out. Maybe give me a few pointers?" I asked.
"Of course mate, no problem. Always happy to help a mate out" he replied with a big grin on his face.
"Cool, just let me know when you are free" I said.
"How about tomorrow after work? My sister-in-law is coming over, and I'd really rather not have to put up with her so anything to get me out of that would be a godsend" he said.
"Sure, if that is fine with you" I replied.
"Not a problem at all, see you here about half 6 tomorrow then" he said.
We said our goodbyes and I headed off to get changed.
The next day at half 6, I headed down to the gym that was situated in the building's basement. When I walked into the changing room, Dean was already there, sitting on one of the benches. He looked up when I walked in and smiled at me.
"Hiya mate. Before you go get changed, I've brought you something that I think will help out during our session". He reached into his duffel bag and took out a white jockstrap.
I must have had a weird look on my face, because he laughed. "I find these are really helpful when I'm working out as they don't restrict me as I do my exercises"
"That's fine by me" I said, and he threw the pair over to me. To be honest, I found jockstraps really hot so the thought of wearing one was already getting me excited. I stripped down (sadly Dean was already changed but looked hot in another tight fitting black Lycra top, and some short white shorts). I pulled on the jockstrap, and it was pretty small. It didn't leave anything to the imagination as you could clearly see the outline of my cock. I then put on my black tank top and pulled on a pair of very skimpy red shorts (hey, I looked good in red). Dean again gave me the once over, flashed a smile and led me out to the gym floor.
After warming up, we made our way to the bench press and I lay down on the bench. Dean selected a weight for me, and stood at the top of my head to spot me. His crotch was right over my face, and the smell coming from him was amazing. I could feel my cock stir and had to think of something else to stop myself from getting hard
We then spent the next hour going around the gym with Dean showing me different equipment to use and suggestions on what weight to use them on.
We eventually ended up at the leg press which involved me sitting down with my knees up to my chest, my feet on the board and having to extend my legs to push the weight away from me.
Dean must have had the weight too high as on my first go, my legs shook and the board nearly went flying back.
"Whoa", he said, "try doing it like this".
He then put both of his hands on my left thigh underneath the fabric of my shorts. I was a bit surprised but presumed he would soon move his hands. He pushed on my thigh to help me extend the leg and bring it back again. However, on the return, his hand moved further up my leg.
Not making a sound, I continued the exercise and every time, his hand moved further up my leg, until his left hand's middle finger touched my hole (thanks to Dean's jockstrap, my ass was easily exposed). I looked at him but he continued to look at my feet.
"Just keep doing the exercise" Dean said.
I continued and on the next return, his middle finger entered my hole. I gasped and looked around the gym. There were a few other co-workers around but nobody was paying attention to us.
I continued doing the leg press, and his finger continued to slide up my ass. After a couple more times, I left out a soft moan.
At this point, Dean turned to me, gave me a smile and inserted his finger all the way into my hole and started to slide it in and out. He had a sly grin on his face, and with the sweat running off him, he looked so hot.
My cock started to stir, and I could feel it getting harder in the jockstrap. The material of both the jockstrap and my shorts were so tight, you could clearly see my bulge as my 8" cock struggled to break free.
Dean saw my straining cock and this only made him go faster, as he slipped a second finger in my hole. He was going so fast, I thought he was going to rip my shorts.
He continued to finger fuck me as my cock continued to get harder. Due to the constraints of the jockstrap, my cock head was rubbing against the fabric, like it was wanking my cock all on its own.
Due to this and Dean's finger fucking, it didn't take long before cum erupted from my rock hard cock into the jockstrap. However, the load was too much and the cum started to leak out, making a damp spot on my shorts.
Dean looked at the damp spot on my shorts, and licked his lips. He pulled his fingers from my ass.
"That was a great workout" he said, "I hope you found it useful".
"Oh, definitely. It gave me a lot of pointers" I replied with a cheeky grin.
"Look, I'm sorry to do this, but I really need to head off" Dean said.
I told him it was no problem and we headed off to the changing room. I undressed and took off the cum-soaked jockstrap. I went to put it in my bag but Dean stopped me.
"Hey, I'll take that home and wash it. After all, it was my fault it was dirty". He laughed.
I handed him the jockstrap. "Maybe we could do this workout again sometime?" he asked.
"Sure thing" I said and he left the room.
I couldn't wait
