As he walked he could feel the water sloshing inside of him, his anus clenching around the plug with each step, his cock swaying. He also noticed the guards skirt moving in the front. He wondered what it was.
At the end of the row of cells was a large white door. It appeared to be polished and in plain black block lettering said "BREEDING ROOM", and below it "AUTHORIZED PERSONNEL ONLY."
The guard opened the door and revealed a sterile room, almost reminiscent of an operating room, with a strange bench in the middle. Next to the bench was a standard medical instrument tray with an array of odd objects he had never seen before, save for one he had seen in an extreme porn video. It was a "ring speculum." A large stainless steel ring with "L" shaped rods spaced evenly around the circumference and wingnuts on the rods. He felt his anus clench in terror, reminding him of the inflated plug in his ass that was holding in the water. His stomach groaned in pain at the water inside of him where it shouldn't be.
He felt his body involuntarily try to reject the plug and expel the water. He winced and the guard noticed.
"Don't worry Breeder, the Harvester will be in momentarily to take care of you. In the meantime, mount the extraction table." She ordered.
His stomach groaned again and a twinge of pain ran through his bowels as he approached the table. It resembled a massage table, only there were lots of restraint straps, as well as adjustment knobs to move the segments of the table and reposition the subject however one pleased. Currently, the table was positioned in such a way that when he mounted it, his knees were at a ninety-degree angle, his legs spread like a woman in stirrups, leaving his plugged asshole exposed (at eye level if one was in a chair behind him), his torso bent over the chest pad at a steep angle in such a way that when he was in place he could see his swollen, pulsating cock staring directly at him.
The guard strapped the restraints on his ankles, calves, thighs, waist, biceps, forearms and wrists. Once he was fully restrained, she walked behind him and removed the leash, leaving the noose on his cock and balls. She snickered in a way that made him tense up, then she grabbed her device, touched it to the underside of his penis, and pushed the button that resulted in a long shock that sent waves of pain through his body. His testicles wanted to retract but couldn't due to the noose, and his sphincter wanted to clench closed but was prevented by the plug in his ass. He bit the ball gag and let out a long muffled scream. She laughed again but stopped when she heard the door open.
"Is ready?" Another woman asked the guard in a heavy accent that sounded Eastern European.
"Yes, Harvester. Only, there was a small issue." He groaned as his stomach churned again. "The dimwit filled himself with two gallons and left it in. I inflated the plug to prevent leakage until you could deal with it."
"Oh. Poor Breeder is in pain likely, yes?" She patted him on his right ass cheek and left her hand there. He was. He let out a muffled grunt of agreement.
"Okay. First, guard must stay. New breeders often squirm." The way she said 'squirm' sounded like Natasha from Rocky and Bullwinkle saying 'squirrel'.
"Next is for breeder, behind you is clear, push now. Will have janitor clean when done."
Push? She just wanted him to push out the inflated plug? He grunted a muffled question.
"I say push." It sounded like 'poosh'. She smacked his left ass cheek this time. Very hard this time. He winced and tried to comply. He pushed a and felt the plug spread open his hole, but he couldn't do it. The plug remained firmly in place. He tried again. He could feel the flared base move outward as his asshole tried to reject the plug. Suddenly he felt something. He felt fingers grasp the exposed base of the plug. Good, they were going to help remove it. Hopefully they would deflate it first. No such luck.
The hand violently yanked the plug out of his ass, the intense pain immediately followed by a hydrant of water. He put his head down and saw his cock, still hard, and behind it a stream of water. The water shot out with so much force that it didn't splash down on the floor of the sterile Breeding room for probably five or six feet behind him. It shot out so hard that his balls didn't get touched by the water until the last drops were leaking out of the gaping hole that was his ass.
"Breeder looks to be empty now. Guard, please bring to me the table behind him. I am curious to measure his hole, very good gape his hole has." Hank was exhausted from shooting out the water. He felt a breeze that entered his asshole and thought 'she's right, I'm gaping.'
"One inch and one quarter inch. Impressive for just an enema." She said. "Guard, this breeder is first time yes? I will attach the sample collector then you can assist me from behind."
Sample collector? Assist from behind? What the hell were they talking about? When they said he was going to be used for breeding he assumed they were gonna make him jerk off in a cup a few times. He began to feel more and more uneasy. The woman with the accent knelt down below him and he was able to get a good look at her. He couldn't get a read on her height with her bent down under him, but she han long blonde hair, soft facial features, skinny frame, and enormous breasts, no bra, and a white lab coat.
She attached what looked like a modified penis pump to him, pumped it a few times to get it to stay in place, then attached wired pads to his testicles. "Am all set in front, begin procedure from your end." She said to the guard.
The guard said nothing, but he felt two fingers enter him from behind and press on his prostate, then start massaging him from the inside. The fingers had went in easily and pain-free after the plug and enema. As she massaged, the Harvester made a comment about no sample. Suddenly he felt the pads on his balls send electrical impulses. She repeated what she said about "no sample" and suddenly the guard removed her two fingers, squirted cold lubricant on his hole, and immediately reinserted her fingers. This time it felt tighter and more uncomfortable, it bordered on a painful stretching.
"Four fingers should work, Lady Harvester?" The guard asked. The Harvester grunted a yes in response. Good god, she had four fingers in his ass. She worked them in and out, twisting left and right with each movement in and out, and pressed on his prostate each time. After a few minutes, his asshole became accustomed to the intrusion and even welcomed it. He was oddly beginning to enjoy it. Suddenly he felt his asshole stretch again and realized she was inserting her thumb. With the realization that he was about to be fisted, he began to shake with a mixture of pain, anticipation, and arousal. Hank bit down on the ball gag with each twisted insertion of the guards hand, he could feel her knuckles pressing up against his asshole. Every few thrusts she would add a drop of lube and push a little harder. She kept working his violated hole and pressing on his prostate. He could feel the tension in his balls, he wanted to cum, NEEDED to cum.
The Harvester reached up between his legs and grabbed the noose and said to the guard "I am release the noose now. He will give sample." At the same moment that she removed the noose, the guard shoved. She shoved harder than she had before. Then, it all happened at once.
The fist entered his ass all the way, sending a shockwave of pain and pleasure through his body, the fist punching his prostate made him release, and he came. His body shivered and shook uncontrollably as he had the most intense orgasm of his life. His balls almost fully retracted as his cock throbbed and pulsated, a continuous stream of cum flowing from his cock and spurting every time the guards knuckles pressed against his prostate. This was the longest orgasm he had ever had. He must have released a gallon of cum (at least that's what it felt like) before he stopped shaking. The Harvester removed the device from his penis and put it away. She had gotten a few drops of cum on her hands during the process and quickly licked it off with a smile. She then got up and walked away. Before she left the room she looked at the guard and told her "I am done with Breeder. You may have fun with him. Sign his release papers and sell him."
