Chapter 4

It’s been five agonizingly painful months for Fendi and Hilton. Their daily injection treatments have swollen their tits to 44 DDD. Their nipples have become extended and fat. Their cunts have both swollen up and blossomed like tulips. Their butts are round and fat. Their heads are still bald. It was decided to have their hair removed permanently because it would increase their value at auction.

The lips on their face have become as swollen and plump as the rims of their puckered assholes.

The girl’s genetics have allowed them to heal rapidly. Scars and bruising usually goes away in a day, but they are now well-tanned from hours of outside training in the nude. They have not been tattooed – that is a privilege reserved for their future responsible party.

Their tongues have been pierced with a heavy dick-shaped metal-alloy piercing. Their nipples have metal bands squeezing them to elongate them and two large brass hoops going through them. The hoops have elaborate designs to make them look like a dick that is fucking its own asshole in an eternal loop.

The same design is used for a much larger hoop that extends through their swollen clitoris. Their clits are forced outside of their pussy so that they are fully exposed. There are six rings on either side of each flap of their pussy.

The piercings serve another purpose besides simple adornment. They are fitted with state of the art nerve stimulation technology. They were gifts from their Uncle Robert. These devices work much like their collar, except they can provide 5000% higher granularity of pain or pleasure stimulation on that particular body part with a simple thought.

Their cunts have been surgically altered so that they can be automatically opened remotely as if a speculum has been inserted and forced their pussies to expand. Their assholes have a similar setting. The last week they have been walking around with their assholes gaping fully open to get used to the feeling.

Despite the painful piercings, the girls are both able to produce milk. They can both be easily milked for two liters of milk per day (one liter per boob).

Their uncle has been training them for the last week at his house. He has a sizable backyard. He has been educating his nieces on the animal play. They have spent the entire week outside in a modified stable barn. Their hands have been sealed into hoove-style gloves so that they cannot use their fingers. Their feet have been locked into high heeled boots that resembled hooves.

Anytime they complained or thought about doing anything other than behaving, they were shocked. There were times they wished they could become chemically controlled because they had to experience and voluntarily submit to every humiliating exercise their Uncle could dream up.

The girls learned to canter, trot, and act as trained ponies to high step and race one another. They were also expected to pull heavy carts using chains attached to the rings in their tits and cunts. It was agonizing work.

Their uncle didn’t own any ponies of his own. He once dominated their mother and father years ago, and this barn hadn’t been used since then. He fucked them nine-ways to Sunday and ran them ragged. Their diet was strictly synthetic cum that had proteins and carbohydrates added to it –along with the real thing from their uncle.

Today, they arrive at their parent’s house. They pulled their Uncle Robert in his spacious 18th-century replica wagon the entire way. They are in full pony regalia with tightly bound leather harnesses exposing their cunts, asses, and tits. They are adorned with feathered headdresses and long black gloves. Their mouths have ring gags placed into them, and their spit is dribbling down over their tits after the long walk across town.

“Well, the girls are starting to look like they may be worth something,” Robert entered the house without knocking. The security system recognized him and is programmed to let him in when he arrives. Robert pulled the girls behind him on chains attached to their collars. He has thoroughly fucked, plucked, and used his nieces for the week, and he has grown bored of his new toys. He is ready to return them to their parents.

“Did you milk them before you brought them home? Their tits look ready to explode!” Rebecca met her daughters at the door and looked them over. They had a few recent bruises, but they were, for the most part, no worse for the wear.

“Yeah, their tits are starting to explode with milk now. I doubled up on the injections this week,” Robert said.

“That isn’t recommended,” Rebecca seemed concerned.

“Their auction is less than a month away. It won’t kill them to have plumper tits dripping with milk,” Robert tweaked Fendi’s left nipple, and milk dribbled down her chest. Fendi kept her eyes straight ahead.

Robert demonstrated the various forms of dressage he taught the girls over the past week at his ranch. The girls high stepped in time with one another. Their shoulders were back, their tits were out, and their butts were high and tight as they walked with precision and purpose on the leads attached to their collars.

“They are almost fully trained. I thought we’d never get here, but I’ve seen augments who were not as well-disciplined as these girls,” Rebecca joked. Augments were trained to be absolutely submissive. The girls were now compliant and well behaved, though. They took their roles as slaves seriously. Hilton and Fendi were still present through every humiliating and painful exercise. They had just adapted to their new situation and accepted their service training.

Hilton was still a little conceited. She was quite convinced she would be the one chosen at auction if only one of them were needed to settle the family’s debts. Fendi’s tits were as huge as her big sister now, though. They were nearly identical in height, and because they were both bald, they looked almost identical from a short distance.

“I’ve got a guy who can train them to fuck dogs and goats,” Robert said bluntly as he led the girls into the Burns house.

Tylenol barely recognized them. His sisters were almost identical now due to the lack of hair and their tits being inflated. They looked like human sex dolls, and they were completely naked. “Which one is Fendi?” he asked.

“I am Sir,” Fendi looked dejected. She tried to pout, but her lips were so swollen no one noticed.

“Is that really necessary?” Rebecca asked Robert if they had to go this far.

“The more money they bring in, the better it is for all involved. They’ve already come this far!” he said.

Their father agreed with Robert. He hated that bastard for making him suck off countless dicks while he was indentured. It had to be done, though. In the long run, the girls would most likely not be released any sooner, but if they brought in enough money from auction, his business would be saved, and he wouldn’t have to sell his wife and son.

The girls looked straight ahead. They had been trained not to look around when others are speaking.

“How do you feel about the training this far?” Rebecca asked her daughters. She too barely recognized them any longer.

“We exist to give pleasure, Ma’am. We have no concerns about our training,” Hilton spoke for her sister. Uncle trained the girls to give responses that would not make their Master’s feel guilty about using them.

“What is the worst part about training as a slave?” Tylenol asked his sisters.
