"What game did you have in mind?" Came the first familiar ping.

"Only the very best gym game - ones that get you a blowjob and orgasm"

"I'm game. How does this work?"

"Meet me in the back hallway, near the stretching area."

I knew I was taking a chance with a stranger, but he seemed like he would be a fun experiment for a game I had been designing in my head for some time.

When J showed up, I waved him over. Confidence overflowing. I challenged him to my elaborate game, explaining the premise and the rules. He was apprehensive at first, eyeing me with cautious optimism. After all, I was a stranger in a gym and we had only 'met' an hour prior. Not to be deterred, I told him explicitly, I wasn't looking for a date, just a bit of fun at the gym. This would start and end here. There would be nothing to take away with us.

"Think you can keep up?" I smirked.

"I love a good competition." He retorted back, and proceeded to glance over his shoulder before dropping the front of his shorts.

I pulled out my phone's timer and set it for 10 seconds. What would seem like a very long 10 seconds, I knelt quickly, and began to lick this stranger's cock. The first round was just a tease. My hands were still covered in chalk, and I had no intention of using them between 'sets' so that I wouldn't have to reapply. Practicality called for quick and dirty games. I swallowed him deep, heard him groan audibly, and felt him harden immediately in my mouth...and before I knew it, time was up. I stood up, gave him a quick smile and sauntered off back to my platform.

I saw him scramble to tuck his now fully-erect cock up into the waistband of his pants as he pulled up his shorts.

I went back to my platform and started my next lift. Deadlifts were a long standing favourite of mine, and I had these programmed in as the last lift of the day. I loaded my bar, repped out an easy warmup set and saw J at his exercise of choice - the reverse hyperextension. I waited for the end of his next set at the water fountain, casually filling my water bottle, and wondering if my game made my absence too noticeable from the rack. I decided to detour and load my next set, before I headed to the back hallway.

As I walked up the ramp I set my phone up for the next 'set'. 30 seconds. J was already around the corner and startled me slightly.

"Ready when you are" He grinned.

I winked at him knowingly and pushed him down by his shoulders so that he was sitting on the stairs facing towards the only entrance to the hallway. I knelt between his legs, and he slipped his already-hard cock out from a leg hole in his pants. I silently wondered if he was hard throughout the last set, Knowing time wasn't on our side, I put my phone down, hit the start button, and began my next round of milking his cock into my mouth trying my best to coax the orgasm out of him. I progressed from slow shallow strokes to faster, deeper ones, sucking in between strokes, hands in front of me on the step below him. I could tell he was having a hard time controlling the urge to cum as his cock hardened and pulsed in my mouth. He was audibly panting, and holding back silent groans of ecstasy. I recognized the tell-tale signs of the onslaught of pleasure I was heaping onto his beautiful cock.

Then, it was all over. The time expired, and I pulled away from him, my drool stringing between his cock and my lips.

"I don't know if I'll last another round." He said, exasperated.

"I wouldn't count on it" I teased back.

I didn't bother trying to watch him stuff his very hard cock back into his shorts as I made my way back to the gym floor. But by now, my own lips were soaking and I wondered if going commando to the gym was a good idea.

My next deadlift set was a bit of a grind, and I knew if I didn't get J to cum the next round, I would 'lose' our little game. After all, 45 seconds was plenty of time to get to an orgasm, wasn't it? I made a motion to clean up my platform a bit, signalling I was getting close to finishing with this station.

Before I knew it, when I watched J from my mirror, he locked eyes with me, and made a gesture into the back hallway. I didn't bother loading for my next set before I reset my phone timer for 45 seconds. I was eager to win my prize and claim my victory at this spontaneous game.

"So, how fast should we make you cum? If we weren't at the gym, I'd love to hear you beg."

The look on his face was best described as shock, mixed with frustration. "Wait, we didn't talk about what happens if I don't make it to the last round?"

"Nothing. I get the satisfaction of winning, and your consolation prize is an orgasm either way!"

He chuckled and nodded in abject agreement as he began to pull his cock out the top of his pants, I knelt down, and put my phone on the floor between my knees and started the timer. With 45 seconds on the clock, I placed my hands on either side of the wall behind him, then got to work. I immediately deep-throated him, focused on the singular task of winning.

He made an audible gasp on the first contact with my throat and I grinned inside, with the sneaking suspicion that this may be an easy win for me. He was still hard from the previous round and while I coaxed the drool from my mouth and swirled it around the head of his cock with my tongue, I flicked the underside of his head on every thrust. His hips seemed to involuntarily thrust into my mouth at this point, and I could feel him clench as cum spurted from the head of his cock and hit my throat. I coughed at the unexpected speed, swallowed and slowed my sucking, gently stroking the underside of his cock with my tongue as he continued to unload multiple spurts of cum into my mouth. I swallowed quickly as my mouth began to fill, but he showed no signs of finishing. Finally, he placed a hand on my head and eased my mouth off his cock. I stood up, wiped my face and planted a quick kiss on his cheek.

I glanced down, and saw the timer countdown.. 3..2...1.. 0. Then a familiar beep in my earbuds.
