Note: This story was dynamically reformatted for online reading convenience. Day twenty-One. Jeri was a magnificent, tall, toned blonde. She had the perfect ruler-like figure. One could only tell that she was a perfect blonde from her hirsute armpits. Girls in the Cybersex Prison were always shorn of head hair and bush. The underarm hair was kept to afford the girls a sense of embarrassment and a trap for their body odors. Bathing was a rare luxury and each girl emanated her distinctive animal scent. The girls were always housed in concrete rooms with only a brown wool blanket. There were no amenities, no tissue, no toilet paper, and no items of personal hygiene. The cell had upper and lower air vents on the left and right walls and a single drain hole, a foot in diameter, centered near the real wall. Jeri knew the routine well. She would be handcuffed and prepared with indwelling catheters, transducers, sensors, wires, and tubes. After preparation she would do her time---twelve hours---on the Internet game grid. After servicing the clients she would be unplugged, fed, watered, and returned to her cell. It seemed to be a typical day. Her time on the game grid was nearly over. She had been molested in the usual assortment of ways and achieved over twenty orgasms. Now she waited patiently while the plugs, wires, tubes, and cables were detached from the blue plate about her privates and anus. From her hypogastric triangle to the cleavage of her buttocks, a blue plastic plate tightly locked in the devices penetrating her vagina, rectum, and bladder. A bra-like device fit over her breasts. The handcuffs clicked, locking Jeri's hands behind her back, and she rose to go to the processing room. On a cold steel table she was relieved as the assortment of devices were removed and the indwelling catheters deflated and eased out. She looked forward to some time sleeping on the brown woolen blanket warmed by heating pipes deep in the concrete floor. She was exhausted and sore. The soreness was endemic. She was always sore from use. Sometimes she was less sore than others, but always sore, swollen, tumescent, and engorged. Today she was directed to another area, not the cell block. What was going on? She entered a strange hall. There were many girls present and multiple cameras: dolly, overhead, and fisheye. The girls were each wearing high heel shoes. About each girl's waist was a thick leather belt. There were two stainless steel rings, front and rear. The girls' hands were cuffed to the side. Their fingertips could only reach the edges of the buttocks or pudenda. Whatever could be transpiring? Jeri was led to a shoe fitting station where she was sized and fitted with a pair of high heel pumps. Hers were red. There were red, black, and white high heel shoes. Jeri noticed a tired look in another girl as she was having her shoes removed and being led away. Most of the girls were wearing red shoes. Those with black shoes were being out-processed. It dawned on Jeri that this was a second twelve hours of duty. She quickly noticed that some girls were dancing, some standing, some exercising, but none were seated, sitting, or resting. "You may not sit," a female matron warned. "You will be fed standing." A thick leather belt was fastened about Jeri's waist and her hands cuffed in heavy leather cuffs to the side. "You may only use your hands to spread yourself," the matron instructed. "You may pull apart buttocks or vulva." There was no way that she could reach the orifices or any other part of her body. The female matron slapped Jeri's breasts. "Understand?" she asked. "Yes," Jeri answered, quickly adding, "Mistress." "Where is the 'thank you'?" the matron asked. "Always beg for use and always thank the matron." "Thank you, Mistress," Jeri appended. She knew that a girl must always beg for punishment or abuse and thank the perpetrator. "Now to the feeding station and then into the 'use pool.' You have twelve hours here. You may be asked to dance or exercise." Jeri was taken to a station where girls were lined up. One by one a matron was shoveling oatmeal into their mouths. They were then given a liter of juice to consume. As soon as they had finished, they were pushed out into the hall full of girls. Jeri stood around for about fifteen minutes. She did not venture to the stage where girls were dancing or the exercise arena. From time to time she would notice a matron approach one of the girls standing around and lead her away. After another wait a matron approached Jeri. "Come with me girl," she commanded. Jeri followed to a side room. She was unused to walking in high heels and had to balance herself. All that she was wearing were high heels and a heavy leather belt. "Against the wall, girl," the matron ordered. "Head against the wall, back towards me, and spread your cheeks." Jeri complied. She figured that this would be the typical body cavity search. Her fingertips were just able to reach about half of each cheek. She was able to part her glorious hemispheres and display her anus. Her brown star nictitated in expectation of the lubricated finger entering and probing. What happened next was unexpected. "Beg for use girl," the matron commanded. "Please use this girl, Mistress," Jeri replied. The matron stood beside her and swung a one-hundred eighty degree arc. The "switch" was a rough rod with many pores. Inside the central shaft of the rod was salt dissolved in alcohol. The switch fell directly across Jeri's anus. She screamed in unimaginable pain! "A girl must not cry out!" the matron admonished. Jeri knew that, but the surprise prevented her from restraining her pain. "You will be rubbed for that later." Jeri didn't know what "rubbed" would be, but it sounded like punishment. She did manage a "thank you." "Thank you, Mistress," Jeri added. Then she knew to continue: "May a girl enjoy another?" The matron was glad to oblige. This time Jeri was able to avoid crying out. The second strike burned and stung. She lost her grip on her buttocks and her cheeks pinched together, concealing and protecting her comely rosette. The matron was angry. "Spread!" she barked. Hot salty tears gushed forth and over hot pink cheeks. She was drooling and mucus fluxed from both nostrils. Jeri struggled to part her derriere again and begged for use. The matron would only be permitted six swats. This was the third. Underhanded the third swat kissed perineum to cleavage. The rod now glistened with alcohol and was speckled with salt. The stinging was intense. "Now turn," the matron ordered, "back to the wall and spread upon that pussy. I want to see clit." Jeri knew that the next three would be along her clitoris, urethral opening, and vulva. At least her asshole would be spared further abuse. Or would it? "Please use a girl well," Jeri begged. She was as convincing as possible. Her rear end burned like fire. She had to tug on flat skin to try and spread her pussy. The leather restrained permitted her little latitude. At last the matron seemed pleased. "Inhale fully then exhale completely," said the matron. Jeri was familiar with the drill. This was to minimize any groan or cry of pain. Jeri inhaled deeply and totally emptied her lungs. It was a good thing that she did as the flexible rod scored a mark from her navel, over the hypogastric triangle, marking her clit, and digging into her pussy lips. Jeri convulsed. Somehow she kept from vomiting. Her head spun. She was sweating profusely and her wet underarms reeked of the scent of fear and pain. There were two more strikes and Jeri believed she was done. She noticed many cameras recording the event. For sure this was on line and being broadcast over the Internet. Then she remembered the "rubbing." "Before you return to the hall, you have some punishment coming," the matron announced. She turned to face several of the cameras. Jeri stood up. "You can resist all you want to girl. You can even cry out. I don't care." Jeri had noticed the two stainless steel rings fore and aft and wondered how they were to be used. The matron attached the end of the rod by its hook to the rear ring and pulled it between Jeri's legs to the front ring. She gave the rod a tug. It began to ease between her legs, the rough surface rubbing tender, sensitive skin. Jeri tried to hold it in place by pulling her legs together. The matron kept pulling. The rod bend and oozed out salty ethanol as it cut ever closer to asshole and pussy. Jeri blanched. This thing was going to rub her anus, clitoris, and labia. She clenched her buttocks as tightly as she could. It didn't stop the thin rod's rasping advance. Jeri tried to turn and pull away. The matron laughed. It just let the rod dig in deeper. The matron pulled and released. Jeri tried to hold it in place with soft tissue. Her privates and rosette were on fire. At last the matron unhooked Jeri and returned her to the main hall. She stood there for over an hour. Her feet were starting to ache in the high heel shoes. She needed to urinate. She asked another girl in a whisper where one could go pee. The girl whispered back: "Here you hold your urine. Don't whisper again, they may catch us." Jeri suffered. Another matron came after another hour and took Jeri to the dance floor. She tried to say that she didn't know how to dance, but knew that that wouldn't help. She had to twist and bounce about a dance pole for two more horrible hours. The need to urinate was becoming acute. Then she was taken to the exercise area. She told the matron that she couldn't hold her urine any longer. The matron laughed. "You can be pussy spanked for peeing on the exercise floor girl." Jeri felt the tears swell up in her eyes. Two hours of exercise and Jeri also needed to defecate. She was surprised that the girls were taken from the exercise arena and allowed to use one of the open toilets. Making her stool was painful. She also felt a sense of urgency. The other girls were waiting, clearly holding their urine and stools. After each relieved herself another girl came along with a rough rag and wiped each one. The rough rag hurt. Jeri was horrified to realize that she had been standing all night long and now would have to return to the game grid. Her toned legs were cramped and hurt from wearing high heel shoes for twelve hours without being allowed to sit down. She had been standing, dancing, and exercising for twelve impossible hours. Now she was to be prepped for another twelve hours on the game grid. A client wanted to see Jeri exhausted and deprived of sleep for his special entertainment. It dawned on Jeri that this might go on for more than one night. She shuddered at the sadism of the high heel shoes, the thin rough rod, and the process called "rubbing."
