I've a slim build guy, not muscly at all, very average. Not everything about me is average. I do have a very large cock. The gym has a reputation. Apparently its a popular gay hook up spot. I've heard lots of stories of guys blowing each other in the locker room or fucking in the sauna. This all has turned me on but unfortunately for me i haven't witnessed any of it. I'm probably one of the youngest members at the gym. Most guys are in their late 20's or 30's. I'm 17 and sort of cute (so I'm told). I do get some attention from the guys but I'm just to nervous to do anything about it. Public sex has never been something I'm into. There is this one guy who i have had my eye on. His name is Jim and he's one of the trainers. He has a super fit body and is about 35 but looks younger. Jim goes around helps everyone in the weights area, spotting them and so on. I would spend most of my time staring at him checking him out. His tight grey t-shirt was almost sprayed on, showing every muscle. The shorts didn't leave much to the imagination either. They show his butt off nicely as well as his package. It looked like his cock was as big as mine. I would spend most nights jerking off to him, imagining him sucking me off and shoving his cock in my 17 year old ass. After i came all over myself i would often wonder how i would make my move. I didn't even know for sure if he was gay. Well the later was soon revealed to me. On Thursday night I had stayed later at the gym later than usual. It was about 9 PM and was finishing up, heading to the showers. From inside the locker room i could hear some noises. I peered around the corner into the shower area and could see Jim with his back to the shower wall with a guy on his knees in front of him. He was getting his cock sucked, and loving it. From the angle i was standing at i could see the guy going to town on his cock. And what a cock it was. He was bigger than me. At least 10 inches from what i could see, and thick too. Jim had his eyes closed and from the noises he was making was about to cum. He pulled out and sprayed streams of white cum all over the guys face. What a mess, good thing they were already in the shower. I went back outside and waited for them to leave before i took my shower. I could have gone in and joined them but to be honest i was still nervous. That night i set my mind to making my move the next time i went to the Gym. Luckily the next time i went was a night Jim was working. I had started on the bench press in Jim's section. Starting on the free wights first i waited for most people to leave for the night. I moved to the bench press and Jim came over to me. "Do you need spotting?" he asked me. "Sure" i said "Thanks" This was the moment i thought to myself. I needed to get his attention. We were not really talking much. He was just coaching me through my set. I started to pump the weights will Jim practically standing over my head. From this angle i could see up his shorts. His cock was in plain view. It was a thing of beauty, my shorts began to swell as a fixed my eyes on his member. I was getting very hard and was obvious. From what i could tell he was checking me out too. He must of liked what he saw because his cock began to grow. Boy was it growing! It was started to swell out the bottom of his shorts leg. I had to do something about this. A brilliant idea sprang to mind. I faked to struggle with the weights. Like i could no longer hold them. Jim took hold of the bar as i took hold of his. I think now i have his attention.
