There were three things that can make waking up from sleep terrifying. The first is waking up someplace other than your bed just as Manhattan Café has. It wasn’t her dorm room that greeted her open eyes but a slightly unfamiliar ceiling. Was this the infirmary? Her head ached. The second thing is not knowing why it was you were passed out in the first place. Usually, it takes a minute to remember why one, but that minute had passed and gave no answer from the shadows of the near lightless room, the moon shimmering through the open curtains the only source for sight. And the third thing is Agnes Tachyon.
“Good morning, Café,” Tachyon said with a little passive grin. “Or should I say evening? Which would make you more comfortable in this situation?”
Café sat up in the bed and gripped the bed sheets reflexively. “The only thing that would make me more comfortable in this situation is if you weren’t here…” Café pushed her thumb in against the bedsheets, feeling the folds of her palm through the thin fabric. “Why am I here and with you of all people?”
There was something about that exact question that seemed to entertain Tachyon, giving her this slow creeping glee like thunderclouds slowly swallowing the sun. Her red eyes were hazy and hollow, looking past the person to see the possibilities. She relished the little moment of confusion, and it was only when Café began to get out of the bed that Tachyon acted.
She pushed her hand gently on Café’s shoulder and stopped her from getting the rest of the way up, keeping her seated with her legs perpendicular to the length of the bed. “You need only relax. I’m afraid there was a mishap in today’s research.”
“A mishap? And it involves me.” Café’s gloomy eyes parted from Tachyon, searching for comfort elsewhere in the room. “What sort of mishap, Agnes…?”
Agnes released Café and gave a slumped shrug with her long sleeves hanging off over her hidden fingers. “Well… In my line of work, one develops many medications that all seem promising. My greatest passion is pursuing the physiological limits of Uma Musume; learning what holds us back as a species and pushing us forward towards our true capabilities.” Café began to try to stand up again, but Agnes gently pushed down both of her shoulders. “And in that pursuit! In that pursuit, sometimes medications are made that seem radical but offer great promise.”
“Did you poison my drink earlier today? The green tea that tasted off during lunch?”
“Not intentionally. I do prefer to get permission for my experiments, but unfortunately… I was storing the concoction in an unmarked water bottle that was then emptied in to your kettle. Luckily, I was storing the medication with a very powerful sleeping drug, so as soon as you passed out on the spot, I knew what had happened and was able to take charge of the situation!” Agnes beamed down at Café who looked less than impressed with Tachyon’s quick thinking and precautions. “So, I sequestered you to the infirmary and was able to keep you hidden away until the effects wear off so you don’t hurt anyone.”
“Well, that’s fine and all but I might have missed—wait? Hurt anyone?!”
“Ah, yes. But not to worry, it appears my hypothesis is incorrect as nothing has yet manifested… Oh?” Agnes pushed her hands down more firmly against Café’s shoulders, slowly leaning in closer towards the girl below her on the bed. “I was so foolish… Of course nothing has occurred yet. The correct stimuli has yet to be applied.”
“Stimuli…?”
Agnes didn’t reply any further. She leaned in closer until her face was ever so close to the other’s. She moved past the face and slowly swept around, bringing her lips closer to Café’s ear. Café… began to pant. A hitched hot puff of air left her throat. Was it fear or something else? Her heart began to pump, and a most irregular sensation rumbled through her body and became pointed at one particular spot. A place on her form that rarely received much focus, that beckoned with attention only after an especially strenuous training session and even then it was only a heat the same way a warm bath might be. This fire that was being lit by Agnes’s gentle breath tickling Café’s ear was an inferno.
Rumbling resonated and grew fiercer and sharper, like glass growing and inflating into sharp bubbles. What was this emotion? This need to do… something. Something Café lacked the vocabulary, the ability to point to. She had this arrow of intense velocity that had to GO but where…? And then Tachyon whispered, “Do you want to hold me down and use me?”
A moan left Café’s lips. Her skirt began to tense, the waistband of her panties grew strained and neared a breaking point, and she felt this elastic burgeoning sensation as if the fire was pushing out of her body. It was 80% of her heat and it was throbbing and pushing forward like a plant growing in fast motion. Café almost felt her eyes cross from how unbearable the sensation was, this insistent thrum coming inches away from her body. And then she felt the tip of it push against Agnes’s stomach.
She looked down.
Jutting out of the bottom of her torso from a nest of two thick balls was a fat throbbing equine shaft that was eagerly kissing Tachyon’s tummy with a steady heady flow of hot hissing pre. It dripped down Tachyon’s clean shirt, those soulless red eyes watching with marvelous satisfaction. What a spectacular performance. How phenomenal.
“W-what have you done to me? What is this… thing?!”
“What is this thing indeed!~” Tachyon felt no shame about what she had done to her friend, happily watching the growth blossom and throb against her. “The mystery of Uma Musume physicality has led me down many paths and theories. The anterior muscles that kiss the ground, the lateral that balance us so we might push forever forward, the medial to push us ever higher towards our limits. But the question is, are there parts of us that could motivate these functions further? Physically? Chemically? Sexually?”
“What…?” Café tried to stammer out further questioning but a single veiny throb from her cock silenced the meek girl and made her feel a slave to her emotions. She was so overwhelmed by how much she needed and how much her mind said she couldn’t that all she could do was quiver and listen.
Agnes just grinned. “I spent so long focusing on what we had that I never once wondered if there was something we were missing! Some terrible component hidden behind the curtain that is our genes, our very being. The mystery of Uma Musume continues on, but hidden further behind our identities is our truths, and some of these truths are those that the world denied. And that truth is breeding. Raucous sex. That which drives birds to sing, cervine to brandish antlers, and horses to run. This is what is missing from Uma Musume! What we were denied in our forms. And I theorized that by reuniting us with our lost…” Agnes smirked at the girth that was now prodding at the bottom of her chin. “Potential~ We might find it in us, be it chemically, physically, or mentally, to be more capable runners~”
This time it was Café’s hands who landed on Agnes. Tachyon made a little “Oh?” sound before Café pulled her down on to the bed and pushed her against the pillow. Agnes looked up as Café’s face distorted from all the lust rushing through her system. She frantically thrust and thrust, gasping desperately for release. “My… my~” Agnes grinned. “Like a beast… Here, you deserve it… Consider this my apology.” Agnes slid her hands down to her bottoms and slid her tights and panties down off her hips. “Do it~”
Without hesitating, Café maneuvered and pushed over and over between Tachyon’s legs. Even then, she was missing. It took careful correction and Anges lifting her legs over Café’s shoulders before finally the head was pushed against her loins. The pair panted in unison. They shared a rhythm that wasn’t entirely different from racing with a rival. Agnes’s eyes glowed with data collection and Café’s boiled over with revenge.
It was instinct. As soon as she was inside it was as if someone had plugged an old program into a new computer, watching as two components that seemingly wouldn’t work together were somehow bonded through a long-supported and steel clad nostalgia. Nerves set signals the brain could understand. The muscles knew what to do to extract as much pleasure as possible from that cock. Café’s hips locked and her legs pushed her forward. She felt the head squeeze through Agnes, and she could feel where it felt best to scrape inward and tease her out. Agnes was so tight too that she had to jackhammer her legs to stretch out her new toy.
There was a part of Café that wanted it to hurt. She needed to get revenge, punish Agnes in some way so she understood how terrible this mistake she made was, and yet Agnes wouldn’t stop smiling. Even when she struggled to keep air in her lungs on account of being jostled and used, even when the thrusts rammed further inside her than anything had ever reached, and even when Café lunged forward and bit her neck dominantly, Agnes just kept smiling with this sort of unbreakable glee. It was a crooked smile cracked into the mirror. Fracture it all you want, you’ll still see it smile, still see those red stars shine through the black stratosphere as if they know something you don’t. She always acted so smart, even when she messed up, she wanted to seem in control, apathetic, above it all. Racing was an inconvenience, just something she’d do if she felt like it. Café felt those emotions roar through her, and it felt harder to stay composed. Something snapped. “Take… it… seriously!!!” She roared, her handsome voice soaring higher into a fever pitch.
Agnes wrapped her arms and legs around Café and sealed her in closer. Café was shocked as she felt it a second after Agnes had. Climax.
Café felt something hot and powerful rush through her. She became aware of every inch of her length in a whole new way. It was like when a dam bursts and suddenly everything rushes out through it. The heat, the arousal, the happiness, all of it congregated into this one propulsion. It all rushed up through the length and pushed out through the broad tip of her cock and it poured into Agnes. And she watched Agnes’s face distort into pleasure, that grin seemingly vanishing for a moment, taken by their shared climax.
She pushed every drop inside of the mad scientist.
“Good girl… Very good…” Tachyon smiled, calmly petting Café. Café slowly pulled herself out of Agnes, watching in a mix of horror and breeder’s pride as a puddle of white departed the spread girl. There it spilled, a trophy of virtue, a mark of what she had done. The connotation of her essence so close, filling Agnes, taking her from inside… Café struggled with the thought and glared daggers at Tachyon.
“Does this… wear off?”
“Most likely,” Agnes smiled. “48 hours.”
“I have… a race tomorrow…”
“Let’s see how you do, then~”
…
The rain poured and wet the field. Uma Musume unprepared found themselves unable to keep their standing steady. It was down to the final stretch. Suddenly, breaking away from the middle pack, Manhattan Café burst forth and found herself closing the distance between herself and fourth place! What was perceived as an impossible gap was overcome! Café swiftly raced past fourth and then overtook third. Second place watched a mad woman truly determined go right past her, undeterred by the proximity of second and first. Despite Café’s smaller frame, she muscled in between the two like a bull, and so startled were they that they couldn’t stop her! Manhattan Café took it!
Applause sounded out and the winner was declared over the loudspeaker! Café smiled and waved to the audience and quickly raced back to her changing room where a certain scientist was waiting for her.
The smug look on Agnes Tachyon’s face boiled Café’s normally demure blood. “Well, well~” Tachyon smiled. Before she could say anything, Café dropped her skirt and pushed her cock against Tachyon’s face.
“Hurry up… I have to do my performance…”
“Of course~” Tachyon said. “I’m curious how a winner tastes. For the sake of my data.”
“I hate your data…” Café grumbled as Tachyon wrapped her lips around the head of the cock. She curled her toes. “S-so much…”
