I belong to an L.A.Fitness gym, a typical middle market commercial facility with a large locker room and a dozen good sized individual showers. I don't have the time (or the interest) to spend hours a day in a gym so my preferred style for lifting is HIT or high intensity training. This often means lifting to failure in one set after a couple warmup sets and can result in a very satisfying pump. Arnold Schwarzenegger has said that a good pump feels as good as cumming in a woman and he's not far off. This sometimes results in my getting aroused complete with a swollen chubb but baggy shorts and a strategic aiming of my flacid sequoia usually keeps things not so visible...but not when doing bench presses.

There's a guy named Scott who's one of several I've become acquainted with on the weights floor, spotting each other or just conversing. Gym buds, nothing more. That day he had helped spot my drop-set bench press set, which is where you strategically put plates on so when you momentarily fail, you quick strip off 25% and continue, repeat. In short order I was drenched with sweat and beathing heavy, down to just the bar and no plates. These give me a super intense pump, and of course a super hard throbbing erection which is blatently obvious thru my shorts laying on my back, hips thrust upward. I'm sure it's noticed but no one says anything.

I thanked Scott, wiped the equipment and retired to the locker room where I stripped my clothes, wrapped a towel and sat on a bench head in hands trying to calm down a bit and not walk to the showers with a monster cock tent in my towel.

Shortly after I started to get some softening whe Scott walks in to a few lockers down and starts undressing.

"You know, I usually don't look or stare or talk about guy's boners but I gotta say after seeing you get hard during that bench press I couldn't believe your size and I not only got hard imagining what it's like having something like that, but watching you walk off with that bulge bouncing I actually came in my shorts" he kinda blurted out while changing and wrapping his own towel. "I've never asked a guy this but could I see it?"

Of course this reversed any softening. I look at him, a bit shorter than average height but very ripped and muscled and decided to make a move. I went over, grabbed his towel and pulled him toward the showers. There was no resistance.

We went down to a stall at the far end of the row, I turned the water on to very warm, and pulled his and my towel off and pushed him into the shower pulling the curtain. Water gushed over both of us, highlighting his slippery white, hairless and muscled body which got me harder. "Can I touch it?" Hell yea. He gripped my rigid shaft with one hand while holding his nice shaped but average hard dick in his other. "Holy crap, I can hardly get my hand around it and it's fucking heavy and huge!" I then pushed myself up against his hardbody, my aching cock and his trapped between our bodies, warm water cascading over us, feeling the hot hardness trapped there. I started rubbing and thrusting against him, and he responded the same. After a few minutes of this he pushed me back, and aimed my cock above his, my tip against his stomach "So this is what it looks like if I had one. You know my wife occasionally pegs me but we don't have a dildo this size". That was an invitation if I ever heard one. He let go and my dick bobbed straight out dripping pre-cum. He ran his finger down the thick vein on top of my dick "I bet there's guys whose whole dick is smaller than this vein."

I crouched, put my hands in between and under his legs and hoisted him up against the wall. With one hand I pumped a couple squirts of hair conditioner from the wall container, lubed my rigid shaft then slowly lowered him on it, spearing his muscular bubble butt and sliding my shiny veined shaft deep inside him. He gasped, arched his body and clung around my shoulders whimpering as I drove into him. I got so deep I felt the resistance and pop penetrating his second hole which made him cry out.

I continued holding him and thrusting into him against the wall, our wet hard bodies sliding in the water, his wet muscles writhing under my hands. As we fucked there was a wet smacking sound as his back hit the wall, I could feel his own rigid dick between us, when with a cry he shuddered and started throbbing, pumping cum between us, the hot cum and warm water lubing our bodies. I could feel him pump while I continued to power him against the wall. Just when he subsided I came, pushing my cock deep inside him as far as I could, throbbing a load deep inside him. My pumping caused him to cum again, another shudder, another cry out feeling his hot cum and the warm water mix again on my stomach and his.

I stood there for a few moments still holding him but my nuts felt like they needed more, so I resumed thrusting him against the wall and moments later came again. At this point he started begging me to let him down, it was starting to hurt. So I did, and he bent over hands on kness panting "Oh my god oh my god I never came so hard in my life. My wife never pegged me so deep, holy shit"

I backed up as far as the stall allowed. It was obvious at this point he was a total submissive. So while he was bent over I slapped him on the side of his face with my still-rigid cock and went "Lick it clean". By this time I had washed my dick clean in the warm water and he started licking my head and shaft. It didn't take much and I came again in his mouth and he stoutly took it all, even though after cuming already a few times there was less than usual.

He stood and I shut off the water and told him to towel off and go out first I'd follow in a few minutes in case anyone was suspicious. The gym didn't like people doing what we just did.

I towelled off but the memory of his hard wet body in my hands, my monster cock deep in his ass refused to go away. He was gone when I came out. I had about a 50% chubb that refused to go down, after I dressed and left the gym I had an obvious dick print. No one noticed, they were too busy working out. I drove home, the memory still live and my dick still partially swollen and aching.

I got home, geeted my very happy dog and spent some time throwing ball in the backyard, which he loved. I had some lunch, still not getting our encounter out of my mind. Being a bit tired after all this I decided to take an afternoon nap, so with my faithful bud snoring in his bedside bed, I took a nap naked under the cooling breeze of the ceiling fan. Of course you know what I dreamed about and woke an hour later with my crotch and bedsheets sticky with cum. So I quick showered then stripped the bedsheets and took them and my gym bag to the shower, tossed in the bedsheets and opened the bag to take out my gym clothes and found a business card with this written on the back "I just wanted to see it, and now my ass is throbbing from it! -Scott".

There could be a sequel.
