Rarity screamed as the needles entered her, but the gag in her mouth muffled it almost completely.

“You know, I was rather hoping one of you gold-diggers would show up.” Blueblood adjusted the machine. “I’ve been wanting to try this out for some time. I’ve been collecting my...fluids, magically treating them.” He adjusted some dials, plugged a bag of the white substance into the machine. “Ponies like you are a real pain. Going after me just because I am nobility. Well, don’t worry. After tonight, we will both have our problems solved.”

Rarity squirmed. The machine glowed with magic, whirred with machinery, and she bit down on the gag as the needles pinched into her. She saw the IV on her right fill with red liquid: her blood leaving her body. The IV on her left filled with the...white fluids, forcing them into her body. Her arm burned.

Tears streaked down her cheeks. She hadn’t wanted this.

“Having second thoughts?” Blueblood grabbed Rarity’s chin. He was surprisingly gentle. “This is what you wanted, isn’t it? To be some trophy wife, to be taken care of for the rest of your life? Well, I’m going to give you exactly that.” Blueblood placed a pair of headphones over Rarity’s ears. “I’ll be back to check on you tomorrow,” he said. “Just relax, and listen to the recording. It’ll help you come to terms with all this.”

Blueblood left, and light filled the basement for a moment as the door opened and shut.

Rarity screwed her eyes shut. She tried to ignore the whisperings coming from the tape, tried to struggle, but her head and limbs were tied firmly in place.

“Relax, submit, enjoy, worship...” the tape droned on and on.

Rarity lifted her head. Blueblood had returned. He had said he would, hadn’t he? At least he kept his promises. He undid her bindings, removed the catheters, led her to a treadmill. The headphones stayed on, continued their droning.

Relax, submit, enjoy, obey, eat...

She should be escaping. Blueblood pointed her to the treadmill, and she dutifully got on. She ran. Her legs began to ache, her throat became dry, but she kept running for hours. Blueblood tinkered with the machine, replaced the bags and adjusted the settings. Then after ages of running, he strapped her back in, replaced the catheters. Instead of the gag, he gave her a bottle. It was full of more semen, it tasted so nice after all that running.

“I like my mares to be fit,” Blueblood said. “You did a good job today.” His words cut through the drone of the headphones. “I’ll be back tomorrow.”

Rarity nodded. The basement door closed, and darkness returned. She sat alone in the dark. Tears streaked her face, her arms and legs and chest hurt, but the contents of the bottle tasted nice.

It had been so long. Rarity didn’t remember what her life had been like before this routine. She would wake up, and the machines would be pumping. Blueblood would make sure she got her daily exercise, whether it was lifting weights or running or whatever else. He would change out the machine’s contents, all the leftover fluids it had collected and spent. Then she would fall asleep, the machines still whirring and chirping, the headphones still droning, her body still aching, less and less each day.

One day was different. Blueblood removed the headphones. “How do you feel?” he asked.

Rarity moved her mouth, but the only that came out was a sliver of drool: salty, white drool.

“Time for you to go to the bathroom,” he said.

Rarity sat down on the toilet he led her to. How long had it been, since she had done this? She relaxed and felt liquid spill out of her body. She looked down, and saw a white substance flooding the toilet.

Blueblood nodded. “Good girl. I think you’re finally ready.”

Rarity clung tightly to Blueblood’s arm. He introduced her to so many ponies, so many nicely dressed ponies. Every time, she would nod. Occasionally she would open her mouth, but no words ever came out, only white drool.

Eventually, the ball ended, and they returned to Blueblood’s mansion. Blueblood removed Rarity’s dress. It had gotten so damp. She had been leaking everywhere all night, from her breasts and her pussy and her mouth.

“Good thing your coat is already white,” Blueblood said. “You did wonderfully tonight. Not a single suckup or gold-digger tried to hit on me.”

Rarity nodded. Her master’s compliments felt so nice.

“I think you’ve earned a fresh meal,” Blueblood pulled out his cock, and Rarity realized how hungry she was. She knelt down, sucked on him, swallowed every drop of semen that came out of him. So much came out. It tasted delicious, refreshing. Had she ever had anything else to eat, besides him? It seemed like a silly thought.

Blueblood turned her over, filled her from her other end. He was always so generous, making sure she had enough nutrition.
