Twilight's eyelids felt heavy. She stirred and lifted her leaden head. It felt unnatural, a chemically induced sleep. The warm comfort of her bed was strangely absent. She blearily opened her eyes and looked at her new, metallic surroundings.

The room was steel plated and bare. It looked more like a pen than a room. Somewhere to keep a violent pet. Sharp edges, bolted corrugated panels and polished steel pipes. It looked... sterilized. Medical.

She tried to turn her head to scan the surroundings but found herself unable to. Leather straps held her neck in place, pinned to a metal ring that had been hooked over her horn.

"H-h-hello?" she tried, her voice sounding cracked and dry as it echoed through the empty, metal room.

She tried to reach up and unhook her horn but found herself once again impeded. Straining her eyes to look down revealed that both her legs were held in iron stocks, securely chained to the floor. Her entire body was suspended a few inches above the ground by a leather harness. She could feel its straps digging into her hips and shoulders as she wriggled.

There was something... dangling... between her legs. Something that felt like it was attached to her body. She felt a chill run through her body as it touched her leg during her struggle. It felt alive. She could... feel... through it... as if it were a part of her own body.

"What is this? What have you done to me?" The only answer was her own voice echoing back at her, "Discord?" Silence, "Chrysalis?" Silence, "Anypony?"

This didn't feel like either of their doing. Twilight bit her lip. It was time to get out of here.

A simple teleportation spell would get her free of these trappings. She closed her eyes and concentrated.

Nothing.

Not even a flicker.

Panic slowly began to rise in her throat.

"What have you done? Why can't I use magic? What have you done to me?" she had wanted to sound angry, indignant and assertive but the voice that echoed back from the fortified walls was that of a very frightened mare.

The strange, smooth appendage dangling between her legs had stopped swinging at last. She could... feel the tip of it. Tingling.

Any second now some new and terrible villain will walk out and start monologuing about how he captured me, thought Twilight. Any second now.

A small slot on the floor in front of her opened and a nozzled pipe slid out. It halted suddenly, a few inches below her chin. She stared down at it, its black eye staring back at her.

"What is this thi-" Twilight was interrupted when a sudden jet of moist vapor puffed out of the pipe. Twilight spluttered, tasting the bitter chemical on her lips, the scent of it filling her nostrils. She squeezed her eyes shut and held her breath. It was too late though. She could taste it on her tongue. Feel it buzzing in her nostrils. She spat onto the steel floor.

The nozzle slowly retreated into the slot from whence it came, leaving the purple unicorn alone once more.

Her head was spinning.

"Please... anypony?" Something was stirring between her legs, "Applejack? Spike? Celestia? Anypony!"

The thing between her legs stiffened rapidly, snapping tightly against her belly, fully erect. It was aching. But not with pain. Aching with... something else. Something that sent shudders rippling through her body.

"No," she squeaked. She could see her reflection in the polished metal wall to her right and left. She could see it clearly now, no longer obscured by her leg. She could see it.

"No!" she could smell it too. Meaty and sour. The scent of a stallion.

"No, no, no, no!" Two swollen testicles, perfectly hairless, each the size of an orange.

"No..." One throbbing shaft, the same shade of purple as the fur of her body. Its angular flare scraped against her chest. It was big. Bigger than Big Mac's. Bigger than Shining Armour's. Bigger than any Twilight had seen. And she'd seen plenty, living in a world where nopony wore pants.

She could still feel her marehood. It was back there, somewhere. Buried deep beneath the wrinkled flesh of her new balls.

The sensation of the... cock... was overwhelming. It muted every other sensation. She no longer even noticed the leather straps digging into her. She was no longer aware of the tight sensation of her bound horn. All of her mind was focused on the monster that twitched between her legs.

"Why do I have a... why would anypony do such a thing... why... how did you...?" she whimpered pathetically. Her whining and moaning was cut off as a bombardment of pleasure shot through her body, "The chemical? S-s-some kind of aphrodisiac... why?"

A throbbing commenced in her 'tailhole'. Each clench of the hole caused a twitch in her shaft, bumping the flare against the soft fur of her chest which in turn induces another clench. The cycle of arousal filled her usually busy mind.

"Gotta... think... gotta... stay focused... use magic to... escape... aaaah~" the cock pulsated, leaking a thick blob of precum onto the floor.

The scent of that one droplet was more overpowering than the aphrodisiac. It filled the air which Twilight unwittingly inhaled in her drowsy state. She could taste it on the tip of her tongue. She breathed in deeply despite herself. So rich. So intoxicating.

She jolted in terror as a loud creaking noise rang out through the room. Twilight could think of absolutely nothing more embarrassing than being seen with a... stallion's... member between her legs. It was enough to make her wish that even if it was somepony here to rescue her they would just go away. Better that than for them to see her in this state.

A slot opened on the far wall and another contraption slid in. It was about as tall as Twilight's bedside table and not quite as wide as the space between her legs, opened wide as they were by the steel stocks that held them.

It was wreathed with a tangle of glass tubes, twirling and spiraling through the machine. It looked more like a water slide in an amusement park with all its twists and turns. Two large cylinders were mounted on the back of the device. They were each marked with a single sticker that featured the following in black capitals:

TWILIGHT SPARKLE: SUBJECT 01

The device hissed to a halt, one hooflength in front of Twilight's face. She stared wildly at it, her heart trying to batter its way out of her chest. There was one tube on it that didn't look like the other. This tube was purple rubber and on the end of it was something that was quickly driving Twilight into a frenzy.

A fleshlight. What other word could there be for it? Twilight had seen them before on that one occasion where she had snooped a peek at her big brother's dirty magazines. Sex toys for lonely stallions. And Twilight was a stallion. And she was alone.

The rubber toy was mounted on the end of what Twilight recognized as a pneumatic piston attached to the rubber hosepipe. She clenched her teeth as her mind grasped the device's intended purpose

"No please you can't do this! Don't! Please! Let me go! Make me normal again!" the device ignored her. It hissed angrily and slowly raised the fleshlight. Aiming it at Twilight's new friend. The mouth of the fleshlight was thoroughly lubricated with a clear jelly which dripped onto the ground as it reached a horizontal angle, splattering next to Twilight's own dribblings. The mouth of the thing was a clumsy and artificial imitation of a real pony pussy. But hairless and rubbery. Twilight gulped. Her own mouth was so dry. It was the last sensation she felt before the fleshlight was pneumatically thrust forward with a hiss of steam.

Twilight screamed. Her body writhed in its bindings and a series of aftershocks wracked through her. The rubber pussy gripped her unbearably tightly. It squeezed down on her as it slid suddenly down her shaft, bottoming out on her swollen sack.

The sensation was unbelievable. It blinded her. Sending colorful orbs swimming in front of her eyes. She was drooling. She couldn't help it. The effort of closing her mouth was simply too much to accomplish. Saliva rained down on the rubber tube as the fleshlight began thrusting back and forth. Her tongue was swaying in the air as her body rocked rhythmically against the pumping machine. She was momentarily one with it. As mindless as the robot.

She snapped back into consciousness as the machine suddenly stopped its motion.

"Don't stop-" she cried and then suddenly, hearing her own words, she snapped her mouth shut. The device hissed and began to suck.

The suction was unbearable. Twilight had filled the fleshlight so completely that the suction created a vacuum around her flare, tugging mercilessly at her most sensitive part. She squealed and heaved at the leather straps.

Something was... changing deep inside her. Something was coming. On some deep instinctual level she knew what the tightening in her balls meant.

The machine started thrusting again. Sucking and thrusting. Sucking and thrusting.

Each time it dragged back down her shaft the suction felt as if it were magnified a hundred times. The lubricant on the fleshlight had been unnecessary. Twilight was leaking so much precum that the rubber pussy was slick and slippery.

"So tight... so tight," gasped Twilight, lost in a dreamy state. Her tail stiffened and flicked.

Here it comes. Here it cums.

The robot seemed entirely unaware that Twilight was in the grip of orgasm, it slammed away at her cock even as the first few steaming jets squirted out. The force and volume of the ejaculation stung Twilight as it stretched open her urethra but she didn't notice the pain. She was drowning in the sensation of it.

The rubber tube was inflated by the coursing flow of marecum being sent barreling down it. Twilight's balls and tailhole throbbed in time with the ripples of semen gushing forth from her. It wasn't like the usual watery specimens. Twilight's semen was thick, with a yoghurt like texture. It clogged and dragged as it was forced down the rubber hose.

The squirting was all that Twilight was. Her eyes lost their usual, brilliant intellectual spark. All she could do was tremble and drool as each creamy flurry left her body.

She stared vacantly down, the leather straps attached to her horn keeping her head from flopping limp. Her cum was flowing through the glass tubes. Rolling over each dip and loop-the-loop that the glass tubes running through the machine took. When every tube was stained a snowy white as Twilight's baby batter pumped through it the machine hissed with satisfaction. Twilight could dimly hear a tinkling sound as the two cylinders on the machine were filled. Her face was blisteringly hot but lost in the haze she didn't notice.

The fleshlight attached to the rubber tube continued its unthinking motion. Occasionally a few droplets would ooze free of its tightly gripping mouth and tickle Twilight as they ran down her legs. Twilight's marehood was leaking as well, adding its own drops to the mess beneath her.

Her heart was still thumping double time to keep up with the shudders of pleasure that ran through her. After what seemed like an eternity the pulsations seemed to slow down.

Twilight's new cock pushed forth its final few gushes.

The machine abruptly halted its ministrations.

It slid backwards and Twilight's member was freed from the fleshlight with a wet popping noise. The penis returned to dangling between her legs, robbed of all its vitality.

The machine retreated into the darkness of the slot from whence it came, carrying Twilight's load off to part unknown for an unknown purpose.

Twilight hung loose in the harness that held her. Empty of all thoughts for the moment. All resistance. All escape plans.
