Jake stripped down the second the heavy door locked behind him. The room was all concrete and steel, with one machine dominating the center like a fucking predator. Thick leather cuffs dangled from the frame, tubes coiled like snakes, and a clear cylinder sat waiting at the end of a motorized arm. He climbed onto the padded bench without a word, spread his legs wide, and let the straps snap tight around his wrists, ankles, and waist. The guy who ran the place didn’t ask if he was sure. He just flipped the switch.
The first suction tube locked onto Jake’s cock with a wet slurp. It was already half-hard from the anticipation, but the machine didn’t wait. It started with slow, rhythmic pulls, drawing his shaft deeper into the warm, lubed sleeve. Every stroke squeezed right under the head, milking the sensitive spot that made his balls twitch. Jake grunted, hips jerking against the restraints, but the straps held him flat. The machine sped up without warning, turning the steady tug into a fast, relentless stroke that had his cock swelling fat and red inside the cylinder.
Pre-cum leaked out almost immediately. The machine sensed it, sensors flashing, and adjusted the pressure so the suction grew stronger at the base while the inner sleeve twisted and stroked the shaft. Jake’s cock throbbed hard, veins standing out, but there was nowhere to go. The cuffs bit into his skin every time his body tried to thrust. He could feel the tube attached to his balls too, gentle but constant vibration keeping them tight and full. Another smaller sleeve slid over the head, rotating slowly, dragging across the slit with every pass.
“Fuck,” Jake growled, voice already rough. Sweat ran down his chest.
The machine kept working him, never tiring, never stopping. It switched patterns every few minutes: fast and shallow, then long and deep, then a brutal combination that sucked hard at the tip while the shaft sleeve pulsed. His cock jerked inside the clear tube, visibly pulsing as another spurt of pre-cum got sucked away. The machine recorded everything, lights blinking, but it never slowed. Jake’s balls ached, drawn up tight, the vibration making them roll and twitch.
He came the first time without warning. The orgasm slammed through him sudden and sharp, cum shooting in thick ropes straight into the suction tube. The machine didn’t pause. It kept stroking through the spasms, milking every drop, the sleeve tightening around the pulsing shaft to drag out more. Jake’s whole body strained against the straps, muscles locked, mouth open on a raw shout. When the last spurt finally tapered, the machine eased off for exactly ten seconds, then ramped back up to full speed.
By the third load Jake was shaking. His cock stayed hard inside the cylinder, oversensitive and dark, but the machine didn’t care. It switched to a new program that alternated hard suction with twisting strokes, forcing more fluid out even when he thought he was empty. Cum and lube mixed in the tube, the machine pumping it away in steady pulses. Jake’s voice cracked on every moan now, words turning into broken curses. “Suck it… fuck, drain me…” The restraints creaked as he fought them, but they held. His nipples were hard, untouched, every nerve in his body wired straight to his cock.
Hours blurred. The machine cycled through every setting it had. Sometimes it focused on the head alone, sucking and nibbling with soft mechanical lips until Jake’s vision blurred. Other times it worked the full length with brutal efficiency, base to tip, never letting him soften. His balls felt swollen and heavy, the vibration sleeve never stopping its low hum. Every orgasm came faster than the last, each one ripped out of him while he lay strapped down and helpless. Cum kept flowing in thinner streams, but the machine still extracted it, sensors adjusting pressure to keep him leaking.
By the time the operator finally shut the machine down, Jake’s cock hung heavy and spent inside the cylinder, twitching with aftershocks. The straps released with a hiss. He stayed on the bench a long minute, chest heaving, thighs trembling, the ghost of the suction still pulling at his skin. The room smelled like sweat and cum. When he finally stood, his legs barely held him. The machine had done exactly what it promised: it had milked him dry, bound and exposed, until there was nothing left to give.
