Chapter 3: The Cistern Incident
The decision to call the doctors sat between them like a third presence, cold and surgical. But before that confrontation, there was the pressure. Always, the pressure. It had become a living thing in the weeks since the penthouse, a constant, simmering ache that made their shared skin feel too tight, their shared blood too thick. The pumps in their warehouse were no longer enough. They needed scale. They needed ruin.
Castor found the blueprints online. An abandoned regional water treatment plant, decommissioned after a new facility was built upstream. Its primary filtration tank—a concrete cylinder fifty feet in diameter and thirty deep, with a central drain large enough to swallow a car. It was perfect.
“It’s a two-hour drive,” Castor said, tracing the access tunnel on the screen.
Pollux leaned over his shoulder, his breath warm. “A pilgrimage.”
They went at dusk. The plant loomed against a bruised purple sky, a geometry of rust and decay. The air outside was clean, cold. Inside, it changed. The smell hit them first: wet concrete, oxidised metal, and beneath it, the sweet-rot stench of stagnant biological matter festering in forgotten pools. Their flashlights cut shaky beams through the vaulted dark.
“Home sweet home,” Pollux whispered, his voice echoing.
They navigated by Castor’s memorised schematics, through a control room with shattered gauges, past silent, corroded pumps. The sound of dripping water was constant, a maddening percussion. Finally, they pushed through a heavy, unhinged metal door and stood at the railing of a gantry overlooking the main filtration tank.
It was a cathedral of decay. A vast, circular pit of stained concrete, its walls streaked with dark, mineral deposits. In the centre of the bowl-like floor, a giant circular grate covered the primary drain. A metal staircase spiralled down into the gloom.
They didn’t speak. The need was upon them, a throbbing urgency that made thought difficult. They descended, their footsteps ringing on the perforated steel steps. The air grew colder, damper. At the bottom, they stood in the centre of the vast, empty basin. It felt like standing at the bottom of a well dug by giants.
Pollux let out a shaky laugh. “No mirrors. No fancy towels. Just… this.”
“Just this,” Castor echoed, his voice flat. He was already pulling at their clothes, his fingers clumsy on the zipper. The act felt different here. Not a clandestine release in a borrowed space, but a ritual in a temple built for processing filth. They stripped their upper bodies, letting their shirts fall to the damp concrete. The cold air pebbled their skin.
The anticipation was a physical vibration. Their shared cock, thick and heavy, was already half-hard, resting against their thigh. The twin heads, nestled side-by-side, were dark and flushed in the beam of the flashlight they’d propped on the stairs.
Pollux’s left hand was the first to touch. His fingers wrapped around the shaft, not stroking, just holding. He hissed. “Fuck, it’s like it’s humming.”
Castor’s right hand closed over Pollux’s. Their grip was unified from the start, no struggle for tempo. Here, in this brutalist expanse, there was only the single, undeniable need. They began to move, their fists sliding in a slow, perfect sync.
The sensation was immediate and profound. Without the constraints of walls, without the fear of discovery, the pleasure expanded to fill the cavernous space. Each stroke was a deep, resonating thrum that travelled up their arms and coiled in their guts. The wet, slick sound of their hands on their own flesh echoed off the concrete, coming back to them from all directions.
“Christ, Cas,” Pollux panted, his head falling back. “It’s gonna be a big one. I can feel it… it’s deep.”
Castor didn’t answer. He was lost in the direct, overwhelming feedback. He felt the ridge of his own head beneath his palm, the smooth glide of the skin, the impossible heat. And through their connection, he felt the echo of it from Pollux’s side, a doubling that made his knees weak. Their rhythm increased, no longer slow, but driving, relentless.
Pollux was vocal, his words bouncing around the tank. “Yeah… just like that… pull it… pull it all out!” His left hand tightened, his knuckles white. Castor matched the pressure, their joined fists becoming a piston.
The crest didn’t sneak up on them. It announced itself with a seismic tremor through their shared pelvis. Their four testicles, drawn up tight in their shared sac, felt like stones grinding together.
“Now!” Pollux screamed, the word tearing from his throat.
The orgasm was not a release. It was an excavation.
Twin geysers, thick as rope and pearlescent white, erupted from the dual slits. They didn’t arc; they shot outward with terrifying force, propelled by pressure that had been building for weeks. The streams crossed in the air, spattering the concrete wall twenty feet away with a sound like thrown mud. Then another pulse, even thicker, a viscous cream that sheeted down the stained concrete.
It didn’t stop. The pulses were long, voluminous, endless. Castor’s vision greyed at the edges, the overwhelming sensation a white noise in his skull. He was dimly aware of their hands still moving, milking, dragging out wave after wave. The fluid pooled around their feet, warm and shocking in the cold air. It quickly covered their ankles, then climbed to their shins.
The sound changed. From individual splats to a continuous, rushing pour. They were a biological fountain, a broken main. The pooled liquid around them was already several inches deep, swirling gently toward the central grate. The smell was immense, a thick, fertile musk that overpowered the rot of the plant.
“Fuck… fuck… it’s still coming…” Pollux chanted, his body rigid, his back arched.
Castor could only grunt, his jaw locked. He looked down. The fluid was at their knees, opaque and churning with their movement. Their shared scrotum was a tight, hairless mound, the four distinct orbs within visibly churning, still pumping. The sight was as horrifying as it was rapturous.
The flood reached their thighs. The warm, viscous tide climbed with terrifying speed, propelled by their own relentless output. It soaked into their discarded trousers, reached the waistband of their shorts. It was at their hips, then their navels. The sheer volume was ludicrous, impossible. A lake of themselves, born in minutes.
As the fluid lapped at the bottom of their fused ribcage, the orgasm finally began to subside, not ending but dissolving into a series of long, shuddering aftershocks that sent thick ropes curling onto the rising surface. They stood, chests heaving, in a pool that reached their shared sternum. The silence that followed was broken only by their ragged breaths and the soft, wet lap of fluid against concrete.
Pollux was the first to move, a slow turn of his head to take in the moat they’d created. His face was slick with sweat, his eyes wide. “Holy shit.”
Castor followed his gaze. The entire bottom of the massive tank was covered. A shallow, milky sea, perhaps three feet deep at the centre, glowing sickly in the beam of the flashlight. The central drain was working, a slow, sucking vortex, but it was hopelessly outpaced. They had functionally flooded a municipal-scale facility with their own ejaculate.
The absurdity of it hit Castor first. Then the grim practicality. “We need to go. Before it seeps into the lower tunnels.”
Wading through the thick soup toward the stairs was a surreal struggle. It pushed against them, weighty and resistant. Each step was a effort. They reached the spiral staircase, dripping, leaving glistening footprints on the rusted metal. They dressed in silence, their clothes sticking to their wet legs and torsos.
As they climbed, Pollux looked back once at the sea they’d made. “We’ll never top that,” he said, and there was a note of genuine mourning in his voice.
Back in the van, the heater blasting, the reality of what came next settled over them. The water treatment plant had been a last, glorious stand against the inevitable. A final testament to the scale of their problem.
Castor started the engine. “We call them tomorrow. Set the meeting.”
Pollux stared out the window at the decaying plant, now holding their secret sea. “What do we even say? ‘We have a leakage issue?’”
“We show them,” Castor said, his voice grim. “We show them the data. The volume. The frequency. We make them understand it’s not a condition. It’s a systemic failure.”
The drive back was silent. The van smelled of them, of the plant, of stale fear. The encounter with the doctors was no longer an abstract possibility; it was the next corridor in the maze. And Castor knew, with a cold certainty, that there would be no temple, no vast space to contain what came next. It would be a small, bright room. And they would be specimens on a table.
He glanced at Pollux, who had finally closed his eyes, his head resting against the window. Castor’s right hand left the gearshift and found Pollux’s left where it lay on the seat between them. He didn’t lace their fingers. He just covered Pollux’s hand with his own, a weight, an anchor. Pollux didn’t open his eyes, but he turned his hand over, palm up, and gripped back, hard.
Pollux didn’t open his eyes, but he turned his hand over, palm up, and gripped back, hard. The van’s heater whined, pushing stale air over skin that still felt phantom-wet. The road home was a black ribbon under a moonless sky.
Their warehouse loft felt different that night. The empty space echoed with more than just their footsteps; it echoed with the decision they’d made. The industrial pumps in the corner, their usual sentinels, looked like pathetic toys. Castor went straight to the stainless steel sink, scrubbing his hands under scalding water as if he could strip away the plant’s lingering scent. Pollux just stood in the middle of the room, looking at their shared reflection in the dark window.
“It didn’t fix anything,” Pollux said, his voice flat. “The plant. It was just… a bigger bucket.”
“It bought us time,” Castor replied, drying his hands on a rough towel. He didn’t believe his own words.
“For what? For them to cut us into neat, separate pieces?” Pollux turned, his face tense. “I can still feel it, Cas. The pressure. It’s right fucking there.” He pressed his left hand low on their abdomen.
Castor felt it too, a stubborn, deep ache that the epic flood at the plant had only temporarily relieved. It was a live wire in their shared core. The doctors were tomorrow’s problem. Tonight’s was this renewed, buzzing need. It hummed between them, a third energy in the room.
“We can’t,” Castor said, though his own pulse was thrumming in his groin. “The pumps are dry. The system’s depleted.”
“Since when has that ever stopped us?” Pollux challenged, a reckless light returning to his eyes. He stepped closer, their fused torsos almost touching. “You felt it down in that tank. That was us. Not some machine. Our fucking problem.” His left hand came up and gripped the back of Castor’s neck. The touch was electric.
Pollux pulled him in, and their mouths met. It was less a kiss and more a collision of need, teeth knocking, breath shared. Castor groaned into it, his resistance dissolving. His right hand came up to cup Pollux’s jaw, holding him there as they devoured each other. This was familiar territory, a fierce, desperate union.
Below, the reality was less harmonious.
Pollux’s left hand dived between them, fumbling with the button of their pants. Castor’s right hand joined, helping to shove the fabric down their hips. Their cock sprung free, already fully hard and weeping. Pollux immediately wrapped his fingers around the shaft, his grip tight, and began a fast, frantic rhythm.
“Slow down,” Castor grunted against his mouth, his own hand covering Pollux’s.
“No, fuck that, I need it,” Pollux panted, trying to maintain his punishing pace.
Castor’s right hand tightened, attempting to control the stroke, to slow it to something more manageable. A tremor ran through their shared arm as their muscles worked against each other. Pollux pulled Castor’s hair with his other hand, kissing him deeper, a messy, open-mouthed invasion. Their tongues fought as fiercely as their hands.
It was a bizarre, frustrating stalemate. From the waist up, they were a single entity of desperate passion, their faces glued together, breath mingling in hot, wet gasps. From the waist down, their shared body was a civil war. Pollux’s left hand jerked in short, aggressive bursts, seeking a quick, violent finish. Castor’s right hand countered with long, dragging pulls, trying to stave off the inevitable deluge that would leave them spent and vulnerable.
“Let go, you controlling bastard,” Pollux hissed, breaking the kiss, saliva shining on his chin.
“You’ll make a mess we can’t handle,” Castor shot back, his own arousal spiking at the struggle.
But neither let go. Their mismatched rhythms created a maddening, irregular friction on their over-sensitized flesh. It wasn’t smooth or pleasurable; it was a jagged, overwhelming scraping that bordered on painful. Pre-come slicked the shaft, making their battling grips slide and catch. The sensation was chaos, a feedback loop of conflicting signals that short-circuited coherent thought.
Pollux wrenched his head to the side, burying his face in Castor’s neck, biting down. Castor cried out, his right hand instinctively clamping down hard, stalling Pollux’s motion completely. For a second, they were frozen, a statue of conflict. Then, as if by silent agreement, they both just started jerking again.
This time, there was no pretense of sync. It was pure, ragged opposition. Pollux would pump three times, fast and shallow. Castor would answer with one long, agonizing draw. Then Pollux again, furious and quick. The pleasure was torn, shredded into confusing spikes and frustrating lulls. It wasn't erotic. It was a raw, ugly manifestation of their shared dread, a physical argument with no resolution possible except collapse.
Two hours passed in this grinding, desperate cycle. Their arms burned with fatigue. Their shared cock, abused and red, ached. The floor around their feet was spotted with droplets flung from their erratic motions. They were drowning in it, in the relentless, unfulfilling friction, in the emotional cum of their fear.
Exhaustion finally forced a truce. Their hands stilled, both simply holding the swollen, throbbing flesh. They stood there, panting, foreheads pressed together, utterly spent but unsatisfied. The pressure still coiled within them, unresolved.
“We’re fucked,” Pollux whispered, his voice hoarse.
Castor had no rebuttal. He looked at their hands, locked in a hopeless grip on their own body. Tomorrow, they would offer this broken machinery to strangers for repair. The thought made him feel more conjoined, and more alone, than ever before. He closed his eyes, and the dark behind his lids was the same for both of them.
