I had recently began working out again at a local gym. It had been a few years since I had had a good lifting regimen so it was much needed. This place a local chain so there were a couple of them but each ran like an independent gym which I really liked. Outside of 7am and 5pm it was never really crowded and for someone trying to get back in shape that was a big plus. Part of the reason I wanted to get back into shape was I had gained some weight, but the other reason was that my sex life was declining. My wife and I had been married for about five years and were to the point where we were having sex about once a month, if that. I'm 30 and she's 28 and we're both in good shape, I just thought if I put on some muscle and lost some fat I put on, she'd be in the mood more. With our declining sex life, I had also been fantasizing and jerking off a lot more. Years ago in college, I had several sexual encounters with men and I had been dreaming of those. My wife knew all about this and sometimes we would even use these as dirty talk in bed, but again that hadn't happened in a while.
Either way, I had been making it to this gym about four nights a week as I wasn't really a morning person. The gym was usually empty or just had a couple others at this time so machines and weights were available and the showers and sauna were free. This was all great, except for one thing: ever since I was in college I have had a fantasy about a hung man using at a gym. Most nights I got a good workout in and went home, but some nights my mind wondered and I found myself jerking off in a shower stall wishing some guy would find me and force me to be his submissive cocksucker. I have to mention that the times I was with men I was very submissive and had an insatiable appetite for cum. This was another fetish that my wife knew all about and without another man in the bedroom, she used to feed me my own cum in different, kinky ways. These shower stall fantasies had become more and more regular lately and I had even been thinking about a particular gym regular. He was slightly taller than I am at about 6'2", I'm 6' even, he was in great shape, and seemed a bit older - maybe 38 or 40. I had been working up the courage to introduce myself and ask if he'd be my workout buddy, but the day I was walking over to him while he was on a treadmill I saw the shape of a large cock bouncing in his shorts. I thought he caught me starting but I'm pretty sure that was my imagination. Still, I quickly walked away blushing and embarrassed. After this workout I had a raging hard on and couldn't get to the shower fast enough. I was always quiet in here because even though I fantasized about being caught, three actual thought terrified me. This night I couldn't help it and as I came and shot my load all over the drain I let out a loud moan and nearly collapsed.
This all continued as normal until one night when everything changed. I had finished up a solid workout, maybe a little too intense. I was horny, but decided the sauna was a better choice to just relax. I sat in the middle wearing only a towel and started to melt away. Suddenly the door opened and I jumped. It was the man I had imagined sucking off... He chuckled and gave me a quick "sorry man," before sitting on the side bench. I started to sweat even more when he dropped his towel exposing a beautiful cock. His body was glistening with sweat and it seemed to make his manhood shine. It was soft and already 6" long and as thick as my cock is hard. I had to pull my eyes away from it, but it was too late... I was starting to get hard under my thin towel.
"Good workout?" The man asked.
"What??" I stuttered.
He smiled. "Did you have a good workout tonight? I've seen you in here the past few weeks."
I blushed, my cock continuing to harden. "yeah, I had a really nice workout. I'm beat."
"Seemed like you had a fantastic workout in the shower the other night too," he said with a grin. I didn't know what to say so I thought about just walking out before he continued, "I'm just fucking with you man! That's what's nice about these late night sessions. You can get a good workout then blow off some steam... Or a load."
I was rock hard, "yeah, I guess. Sorry I'll try and keep it down."
"You're fine, I'm Chris by the way." As he reached out his hand.
"I'm Case," I shook, still blushing.
"So Case, are you a cocksucker?" Chris asked, staring directly into my eyes.
Panicking, I blurted out "no, I'm married."
"It's funny because you were starting at my crotch the other night when I was running, then you were jerking your cock in the shower just a few minutes later, and now you keep staring at my cock. Not to mention the tent your pitching under that towel," Chris motioned downward.
I was speechless. At the same time I was getting more horny. Before I could think, Chris quickly reached over and opened my towel, my hard cock sprang free, pointing straight up.
"It's ok Case, it's just you and I here and I could really use some head."
"Seriously, I'm not..."
