A tight, toned redhead banged on their bars after breakfast on the third day after their arrival. "Okay, you pieces of shit, your turn." The cell door unlocked and slid open. "Strip and get moving ladies. We're going to the milking room!" she drawled.
Zach and Rodriguez peeled out of their clothing and walked out of their cells, two more guards bringing up the rear. They had shaved the night before and one of the screws inspected their manhood to make sure. Rodriguez looked as unaffected and disinterested by the whole procedure as was possible while the other inmates still in their cells hooted and pointed at them.
"Hard yet?" one of them called to Zach.
Another answered, "He ain't even made it to the milking room! He already done cum. Whip his ass, boss lady!"
"I heard him bust a nut shaving! She gonna cut it off this time!"
Humiliation didn't begin to describe what Zach felt.
Finally, they got to the end of the cell block and went through a door and then another door which led to a corridor barely wider than his shoulders. Moans of pleasure or pain--Zach didn't know which--came from the light at the other end. The lead guard stepped aside and shoved Rodriguez through and the other guard followed.
"What the fuck is this, bitch?" Rodriguez said from the other end. Zach heard a meaty thud and Rodriguez cried out. He heard the sounds of metal clanging and the rip of Velcro and in a few seconds, she heard him gasp.
Zach was terrified now as the lead guard shoved him down the corridor to his fate. He wanted to run but there was nowhere to go, the only escape blocked by the guard behind him who had no shortage of means to incapacitate him. Ahead of him was something that looked like a cot turned on its end. Thick material was stretched across a frame a bit taller than Zach. Wide straps dangled from the sides. He saw a hole at head height and another smaller one at waist level.
He wanted to cry--did cry as he was shoved roughly against the thick webbing. Zach felt the straps pulled around his shoulders, his lower back, and above his knees. He was locked into a frame, unable to move in any direction, his arms pinned at his sides. The holes in the webbing allowed him to poke his head through. What he saw on the other side caused him to moan in fear as the entire frame moved to the tilted forward. He quivered violently and was vaguely aware of another inmate being strapped in beside him.
Now he could see into the room beyond. It was round and ringed with other prisoners similarly secured. Some were quivering, others moaning. Some had their eyes shut, some of their mouths gaped open, working like a fish out of water. He watched as a muscular black guard moved to one of the prisoners, gripped his penis with one hand, and proceeded to swab some sort of clear, thin jelly-like substance up and down his flaccid length. Zach smelled a faint chemical aroma and figured this was some sort of disinfectant. The guard picked up something that looked like a black sock. Both ends appeared to be open, small wires leading from the material. The guard slipped the sock-like sleeve over the fingers of one hand, reached and pinched the head of the prisoner's penis in her fingers then slid the sock over his length with the other hand leaving him encased in the material from almost the base of his shaft to just below the head. Then, she slid a clear, curved shield up and locked it in place in front of the prisoner's groin.
Zach cried out in shock as he felt his own penis gripped and stretched from his body. Another guard had him in her grip. He hadn't seen her coming and instinctively tried to pull himself out of the hole in the webbing but the straps across his legs and back held him fast. As the cool disinfectant was swabbed onto him Zach began to sob. He was more scared and confused than the day he'd been processed into the Big House.
The guard pinched the head roughly and Zach frantically tried to get out of her grip, but before he knew it, she'd slid the sock-like thing down his length. Whatever it was hugged him firmly and Zach was reminded of the time he'd worn a wet-suit waterskiing a few years ago. Like the wetsuit, it didn't hurt but gripped him snugly. He watched the guard click the clear shield into place in front of him and felt light-headed. He forced himself to calm down to calm down in the face of the incipient hyperventilation creeping up on him.
"Dear god, what have I gotten myself into?" Zach sobbed softly.
At first, Zach thought one of the guards was tickling the bottom of his cock. He looked down and realized there was nothing down there, just the black sleeve holding him. The sensation built gradually and Zach realized it actually felt nice. He closed his eyes, not sure what to think of it so he thought nothing for a long moment. The tickle turned into a tingle that felt to him like a million tiny fingers dancing on his manhood. It was almost the same sensation as his arm might have if he'd slept on it, except without the discomfort.
As the sensation intensified, Zach felt himself respond. Whatever they were doing to him was giving him an erection. He felt he couldn't have willed himself to do otherwise if someone had held a gun to his head. Inexorably he swelled as the sensation intensified even further and now he realized why most of the other inmates were moaning and writhing.
He thought at some point, as he became increasingly more turgid, that the sock would begin to get too tight but he soon found as he continued to increase in girth that the special weave in the material allowed it to expand as the flesh within swelled.
The tingling continued to build and Zach's head lolled back. He was completely erect now, throbbing within the sleeve surrounding him. He moaned as the sensation changed to more rapid and intense tingling and Zach felt his cock dance. It was unlike anything he'd ever experienced.
"Oh fuck!" he gasped. He had now joined the chorus of sounds of pleasure in the room, his hips thrusting against nothing. It wouldn't be long before he came if the sensation continued. The tingling slowed, became less intense, then rapidly sped up again with its intensity increasing and it felt to Zach almost as if his penis were sliding in and out of the tiny fingers. He looked down at his cock which curved to the ceiling and spasmed once deep in his groin, a drop of clear fluid forming at the tip. The sensation continued to cycle up and down and the urge to thrust was overwhelming. He succumbed to the urge, thrusting as much as the frame and webbing would allow.
Zachary was not gay and had never allowed himself to be taken by any other of the inmates at his home prison. Nevertheless, he watched as Rodriguez's cock ejected a stream of semen which splattered against the shield and dribbled down to a funnel-like section that collected it. Now he knew what the clear, curved shield in front of him was for. Zach was close to that point himself in his own private ecstasy but vaguely aware that a couple of inmates were being released from the contraption by the guards and allowed off the frames.
The urge to orgasm was building mercilessly and Zach felt his testicles tighten. He whimpered with pleasure, his cock dancing to the sensation surrounding it. Soon he was so close to the edge he felt as if his cock would explode if he didn't cum within the next few seconds. His balls were a knot now and the pleasurable sensation of pressure deep in his groin built signaling the beginning of his climax.
Then, right as he came to the edge of orgasm, the tingling sensation ceased.
"Fuck!" he cried in frustration. He had not masturbated for a week before he came here and the additional three days after that. Zach needed--had--to cum or something would burst. He looked down at his erection waving helplessly, a string of clear pre-cum leaking out now.
"Oh, looks like the feedback system is working well on this one," the black female guard said smiling at him as she leaned against the wall nearby. The short guard that had put the sleeve on him came over and stood in front of him.
"What are you doing to me?" Zach gasped. "Please turn it back on. I was so fucking close!"
"We are not doing it to you," the black guard said. Her name tag said, Harris. "The system is."
"What are you talking about?"
"The milking frame you're in is loaded with sensors," the short guard, Jenkins, said. "So is the sleeve I put on your dick. They measure things like muscle tension, skin moisture, heart rate, breathing, a few other things too, like--" She searched for the word a moment then smiled as she said it. "Tumescence."
