He strapped the guy face-up on the padded table, thick leather cuffs locking wrists and ankles to the corners so his body was spread wide and helpless. The sub’s cock was already half-hard from anticipation, balls heavy and low. “You’re not shooting once tonight,” the dom said, voice flat and filthy. “You’re gonna cum until nothing’s left and the machine keeps pulling it out anyway.”
He wrapped conductive loops tight around the base of the cock and just under the head, then pressed sticky pad electrodes on either side of the shaft. A smooth steel probe, lubed thick, slid into the sub’s hole and seated against the prostate. Wires ran from everything to the black estim box on the side table. The dom flipped the power on low, and the first steady throb hit the cock and prostate at the same time.
The sub grunted, hips twitching against the straps. The current pulsed in slow waves, making the cock jump and swell fast. Pre-cum beaded at the slit and ran down the shaft. The dom watched for a minute, then cranked the intensity and added a milking rhythm—short, hard bursts that made the prostate contract hard. The sub’s back arched. His cock jerked once, twice, then ropes of cum shot up his stomach without any hand on it. First orgasm, and the machine didn’t stop.
It kept pulsing right through the sensitivity, turning the aftershocks into the next climb. The sub started cursing, pulling at the cuffs, but the straps held. The dom reached in and attached a clear plastic milking cylinder over the still-hard cock, sealing it with a tight ring. A low vacuum started sucking while the estim kept firing. Cum from the first load was already being pulled into the tube.
Second orgasm hit faster. The sub shouted, body straining, and more thick spurts filled the cylinder. The machine didn’t ease off. The dom adjusted the settings so the prostate probe gave short, brutal zaps timed with the cock rings. Every zap forced another contraction. The sub’s balls drew up tight again. Third load came out thinner, but the cock stayed rigid, twitching inside the tube while the vacuum kept working.
Sweat ran down the sub’s chest. His nipples were hard, so the dom clipped conductive clamps on them and wired them into the same box. Now every pulse hit cock, prostate, and tits together. The sub started moaning nonstop, voice raw. Fourth orgasm ripped through him with almost no warning—just a sudden full-body clench and a weaker spurt that the vacuum sucked away immediately.
The dom turned the power higher. The sub’s thighs shook in the cuffs.
His cock was dark red and swollen inside the tube, kept hard by the current even as it was milked dry. Fifth orgasm was dry at first, just the prostate forcing the muscles to squeeze, then a thin dribble leaked out. The dom kept the rhythm going, watching the sub’s face twist between pain and overwhelming pleasure.
By the sixth the sub was babbling, begging without words. Cum and lube mixed in the tube. The dom switched the estim to a constant high-frequency buzz on the prostate while the cock rings gave sharp, rhythmic shocks. The sub came again, body locking up, a long, broken sound coming out of his throat. Nothing much came out this time, but the contractions kept happening anyway.
The dom left him like that for another ten minutes, machine running steady, vacuum sucking whatever was left. The sub’s cock gave a few more weak pulses, then finally started to soften inside the tube even with the current still on. Only then did the dom kill the power and pull the wires.
He unstrapped the sub slowly, rubbing circulation back into the wrists and ankles. The sub lay there wrecked, chest heaving, cock limp and shiny with lube and the last traces of cum. The dom wiped him down with a warm cloth, then leaned over and kissed him hard.
“Next time we go for eight,” he said. The sub just groaned and nodded, already half-hard again at the thought.
