I entered the outer tunnel past the stairs to the surface, with the sole intention of pissing there. My bladder was extremely full from the beers I had drank, and I wanted to squat to pee, so I didn't take advantage of the bathroom in the club and made my way back here. The tiles were grimy and it was dark, with the last light coming from the staircase behind me. I saw a drain on the floor, and, made my way to it, not wanting to make an unnecessary mess everywhere. My legs were twisted around themselves as I looked around one last time to make sure I was alone, before I started preparing to finally pee. My pussy throbbed with urgency as I lowered my pants preparing for the release it so desperately craved. I wasted no time, and squatted over the drain, but just as the first drops of liquid relief exited me, I heard someone move in the shadows.
My body wanted to finish urinating very badly, but the noise had startled me, and caused me to clench up. I looked up and saw a man approaching me, I stood up quickly, and met his eyes. He was muscular and wearing a tank top. He was clearly also a patron of the club, perhaps also looking for a secluded place to relieve himself.
“Hey there,” He greeted me smiling, looking pointedly at my slightly spread legs, and my still dripping pussy.
“Hey,” I answered him, then added, “mind if I piss in front of you? I'm dying to go.” I was gauging his response, inviting him at the very least, to observe. He grinned.
“You like holding it? I have an idea if you're game.” He began running his hand across his crotch, almost like he couldn't help himself.
“Please,” I gasped, I still needed to go beyond badly, but the idea of denying myself further suddenly became deeply appealing. He walked closer to me, and then without a word he dropped to his knees before me. I spread my legs as he inspected me,
“Alright don't pee unless I say alright?” With this he opened his mouth and lazily ran his tongue around my pussy. I made a soft sound, the wet feeling of his mouth seemed to double my urgent need, and his tongue teasing my clit began to arouse me beyond belief. The small amount of pee that I had been able to release before the mans arrival seemed to have lubricated my urethra, and my bladder did not appreciate the teasing. I felt it clench, and as he pushed my legs farther apart a little spurt managed to escape.
“Oh fuck sorry,” I said, as I breathlessly ground into his hot mouth. He sucked harder at my clit then, and ran his tongue flat over my urethral opening, causing me to cry out with frustrated pleasure. I pictured the beers I had drank, suspended over this mans beautiful face, with the only thing keeping him dry being my weak urethra, which he was teasing relentlessly.
“Please let me pee,” I found myself begging. “Ooh I have to go so badly please!” He groaned against me as he continued to paw at his own crotch. He pulled back for a second.
“I'm holding too,” he explained. “Will you let me pee on you?” I then realized he was gripping himself tightly through his pants, holding himself tightly shut. I nodded breathlessly. He rose, and before I could process what was happening he had taken his cock out and aimed it between my legs.
“You may not go until I'm done alright?” He murmured.”And Im so full who knows how long you'll need to hold.”
Without the distraction of his mouth on my clit, my need had risen to a favor pitch, but fuck, it was nothing compared to my need once he started peeing.
He wasn't kidding about needing to go badly. His stream was hot and strong and he focused it on my throbbing clit, which twitched beneath the onslaught of liquid. He groaned in relief, and I groaned in deep terrible frustration. The sensation was in many ways, very similar to peeing: pee ran down my legs and pee was washing over my urethra itself, but my bladder grew no lighter.
It was every terrible torture I had ever subjected my bladder too all at once. It was watching another man enjoy something I was denied of. It was waterfalls and warmth and trickling sounds and teasing touches where I needed it most. I wanted badly to rub my clit, but I didn't want to get anything in the way of his release playing over my genitals, so I moaned in deeply aroused frustration instead. Finally, his bladder was empty, and the sweet torture stopped. He knew what I needed as soon as he was done, and quickly began rubbing my clit,
“You ready to cum?” He whispered to me, I nodded
“I want to pee so badly,” I begged. “God I'm so full... ohhh...”

His hand sped up and I got closer and closer.
“Piss for me.” He breathed, although at that moment I didn't have a choice. I was cumming, and I was finally finally peeing. I ground into his fingers hard, and covered his hand in my warm release which came out in jets as I clenched though my orgasm. Finally getting to release my pee lengthened my orgasm tremendously, and I was shaking by the time I was empty.
