Draining the Tank

The warehouse was always cold, a cavern of concrete and steel that smelled of cardboard and dust. It was long after hours, and the only light came from a single security lamp casting long, distorted shadows across the floor. I was looking for a misplaced invoice, a needle in a haystack of pallets, when I heard it. A soft, rhythmic sound, a choked-back gasp. I followed the noise to a secluded corner behind a stack of industrial shelving.
And there he was. Mark.
My business partner. My friend. The man I’d known for ten years, the one who wore his three-year marriage like a lead weight around his neck. He was leaning against a corrugated steel wall, his suit pants pooled around his ankles, his shirt unbuttoned. His eyes were squeezed shut, his face a mask of desperate frustration as he worked his cock with a furious, almost angry, rhythm. It wasn't the act of a man enjoying himself; it was the act of a man trying to cure an itch he couldn't reach, a pressure building to an explosive point.
I cleared my throat. The sound echoed like a gunshot.
Mark’s eyes flew open, wide with pure, undiluted panic. He fumbled, trying to cover himself, looking like a kid caught with his hand in the cookie jar. A very large, very hard cookie jar.
"Jesus, Alex! What the hell are you doing here?" he stammered, his face flushing a deep, blotchy red.
"I could ask you the same thing, Mark," I said, my voice even. I wasn't judging him. I was just… observing. I'd never seen him look so vulnerable, so broken. "Having a little trouble at home?"
That was all it took. The dam broke. He sagged against the wall, pulling up his pants with a sigh of defeat. "Trouble? Alex, it's a goddamn desert. A sexless, loveless desert. We haven't so much as kissed in six months. I sleep in the guest room most nights. I'm thirty-five years old and I feel like I'm going to crawl out of my own skin. I'm so backed up I can't think straight."
I leaned against the shelving opposite him, crossing my arms. "You know, for a guy who's always been a bachelor, I've learned a thing or two. You're not horny, Mark. You're not just 'backed up'. You're overflowing. Your body is screaming for a release that your brain isn't getting. All this tension, this frustration... it's got nowhere to go."
He just looked at me, his eyes pleading. "So what am I supposed to do? Divorce her? I can't."
"No," I said softly. "You're not supposed to do anything drastic. You're just supposed to get drained. Regularly. Like changing the oil in your car. It's basic maintenance."
A flicker of something—hope, confusion, disbelief—crossed his face. "Drained? What are you talking about?"
I pushed off the shelf and took a step closer. The air between us grew thick, charged. "I'm talking about taking care of the problem. I'm talking about a friend helping a friend. No strings, no weirdness, just a biological function. You need to empty the tank, and I'm offering to be the valve."
Mark stared at me, his mouth slightly agape. He was processing it, the sheer audacity of the offer. I could see the war raging in his head: the loyal husband versus the desperate animal. The animal was winning.
"You're serious," he whispered.
"Never been more serious in my life," I said, my voice dropping to a low murmur. "Now, are you going to stand there looking like a scared rabbit, or are you going to let me help you?"
He didn't answer with words. He just gave a tiny, almost imperceptible nod.
That was my cue. I closed the distance between us, my hand moving to replace his on his belt. I unbuckled it slowly, the sound of the leather a sharp crack in the quiet warehouse. I popped the button on his trousers and pulled down the zipper. His cock was still hard, straining against the fabric of his boxer briefs. I hooked my fingers in the waistband and tugged them down.
His dick sprang free, thick and heavy and already beading with precum at the tip. It was an impressive piece, and it was practically vibrating with need.
"See?" I murmured, my breath warm against his ear. "All this pent-up energy. It's a crime to let it go to waste."
I wrapped my hand around the base of his shaft. It was hot, velvety steel. He let out a sharp hiss, his head falling back against the wall. I started slow, my grip firm, sliding my hand from the thick base to the swollen crown. I used his own leaking precum as lube, swirling my thumb over the sensitive slit, spreading the slick fluid over his head.
"Fuck, Alex," he groaned, his hips jerking forward instinctively.
"That's it," I encouraged, my voice a low growl. "Don't hold back. Let it all go. You've been holding this in for way too long."
I picked up the pace, my fist becoming a blur on his cock. I wasn't just jerking him off; I was milking him. My strokes were long and deliberate, squeezing and pulling, designed to draw every last drop of frustration from his body. His breathing grew ragged, his hands clenching into fists at his sides. The warehouse was filled with the wet, slick sounds of my hand on his dick and his desperate, guttural moans.
"I can't... I'm gonna..." he panted.
"Not yet," I commanded, slowing down just enough to keep him on the edge. "We're not done yet."
Before he could protest, I sank to my knees on the cold concrete floor. I looked up at him, at the wild, desperate look in his eyes, and then I leaned in and took him into my mouth.
The taste was clean and salty. I took him deep, my lips sliding down his shaft until the head of his cock hit the back of my throat. I hummed around him, the vibration making his entire body shudder. I used my tongue, laving the sensitive underside, tracing the thick vein that pulsed with his heartbeat.
I grabbed his ass, pulling him deeper, fucking my own face with his cock. I was in control now. I was the one setting the pace, deciding when he got to come. And he was completely at my mercy. His hands found my hair, his fingers tangling in the strands as he guided my head, his hips starting to thrust, losing himself in the raw, primal pleasure.
I could feel his balls tightening, drawing up against his body. His thighs began to tremble. He was right there.
"Alex... I'm... oh god, I'm gonna cum," he warned, his voice strained.
I didn't pull back. I doubled down, taking him as deep as I could, my hand cupping his balls and gently tugging.
With a loud, guttural roar that echoed through the entire warehouse, he exploded. Hot, thick jets of cum flooded my mouth, coating my tongue and throat. It was a massive load, weeks of pent-up frustration finally finding its release. I swallowed it all, greedily, milking his pulsing shaft until he was spent, his body slumping against the wall, completely drained.
I pulled back, wiping a stray drop from my lips with the back of my hand. I looked up at him. He was panting, his eyes closed, a look of profound relief and utter exhaustion on his face. He looked ten years younger.
I stood up, straightening my tie. "There," I said, my voice back to its normal business-like tone. "Maintenance complete. Feel better?"
He opened his eyes and looked at me, a slow, genuine smile spreading across his face for the first time in months. "I feel... human again."
"Good," I said, clapping him on the shoulder. "Because this is going to be a regular thing. Tuesdays and Thursdays. After work. We'll consider it a new company benefit."
