She Sold Her Body Behind Your Back

The evening sky outside Tracen Academy had long turned into pitch-black darkness. You were sitting alone at home, staring at the cooling dinner on the table, wondering where your spouse and trainee had gone. Your calls went unanswered, her phone buzzing continuously on a wooden bench in the empty Tracen swimming pool locker room.

Inside the steaming, dimly-lit locker room, Agnes Tachyon stood dressed in nothing but a skimpy, glistening gold bikini that barely covered her chestnut-haired, slender frame. A large, completely naked, sweaty man stood beside her, his left hand roughly and lewdly squeezing her barely-concealed right breast, molding her soft flesh in his firm, possessive grip. In his right hand, he flourished a thick, heavy stack of cash, waving it tauntingly right in front of her eyes.

Man: "Look at this fat stack, you greedy little scientific whore. The more times I cum deep inside that womb of yours, the more of these you get to keep for your fucking research. Now get to work!"

Without a second thought, driven by her unhinged obsession to fund her experiments on the outer limits of speed, Tachyon yielded. She had been secretly selling her body behind your back for quick, easy funding. They moved directly into the adjoining, vapor-filled shower room. The naked man sprawled flat on his back upon the slick, wet tiled floor, his thick, swollen penis standing erect under the cascading warm water.

Tachyon straddled his waist, guiding his rigid shaft to her drenched, aroused entrance, and plunged her hips downward, impaling herself completely. Her chestnut tail lashed uncontrollably in the damp air as she began riding him with relentless, desperate intensity, bouncing hard on his cock.

Agnes Tachyon: "Ah-ha...! Yes...! Fill me... give me more... research capital...!"

Aah...! Ngh...! The sheer... neurochemical overload...! My brain is... melting...!

The tiled walls of the shower stall echoed with the filthy, visceral sounds of unbridled lust.

PLAP PLAP PLAP

Just a few meters away on the locker room bench, her smartphone vibrated ceaselessly, flashing your name on the screen as you tried to reach your missing wife. Tachyon didn't even notice it. Hours passed, and she continued to violently bounce up and down on his shaft, milking him unforgivingly.

Man: "Yeah, take it! Take every fucking drop, you insatiable bitch!"

With a rough, guttural grunt, the man thrust his hips upward and shot his thick, hot seed deep into the furthest depths of her womb. Tachyon's back arched wildly, her sensitive ears pinning back as she shrieked in an overwhelming, mind-shattering orgasm.

Even as his warm, heavy ejaculate filled her interior and leaked down her thighs, they didn't stop. The man remained rock-hard inside her, and Tachyon kept frantically riding his penis, drowning in mindless, filthy pleasure, climaxing again and again while completely ignoring your desperate calls.

Your phone buzzes with a notification from an unknown, encrypted number. With trembling, unsteady fingers, you press play on the incoming video. The screen illuminates, revealing a dimly lit hotel bedroom. Agnes Tachyon is sitting completely naked on the edge of a plush mattress. Standing right in front of her is a tall, muscular, naked man. She smirks, playfully stroking the head of his erect penis with her palm before wrapping her lips around his shaft, licking him enthusiastically. She teasingly flicks his glans with her fingertip, marveling at how veiny and hard he is.

Man: "You think it's a game, you greedy bitch?! Let's see how much you like this!"

The man gathers her hair in his fist and roughly rams his entire cock deep down her throat, fucking her mouth with brutal, unforgiving thrusts.

PLAP PLAP PLAP

The filthy, wet gagging sounds echo clearly from your phone speaker until the man groans, thrusting deeply one last time and ejaculating a massive, viscous load straight down her esophagus. Just as she gaspingly swallows every drop, the video cuts black, and a glowing pop-up banner appears: 'Pay $500 to unlock the rest of the uncensored archive.'

Before you can even process the shattering betrayal, the front door clicks, and footsteps approach. The bedroom door swings open, and Agnes Tachyon walks in, dressed in her casual purple top and short pants. She looks utterly drained, sweat glistening slightly on her collarbone.

Ngh... that took far more physical exertion than expected... but at least the funding for my next speed enhancer is fully secured...

Her eyes lock onto you, noticing your pale, horrified expression and your shaking hands holding the phone.

Agnes Tachyon: "Ah, my dear guinea pig... I'm finally home. I quite missed you, you know. Research outside the lab is... exhausting. Hm? What is with that utterly stunned, bewildered look on your face? Did one of my beakers explode, or are you simply overjoyed to see your beloved wife return?"

Agnes had been completely missing for two agonizing weeks, leaving no trace behind. Suddenly, your phone vibrates with an urgent notification from Manhattan Cafe, containing a direct link to a live stream along with a hesitant text: "What... is Tachyon... doing...?"

You click the link, and the video feed opens. Agnes Tachyon is sitting on a luxurious bed, wearing a revealing silver dress with an extremely plunging cleavage. The skirt is hiked all the way up her thighs, proudly displaying her skimpy black thong. Sitting beside her is a completely naked, muscular man. Her left hand is lazily stroking his erect penis while her right hand waves cheerfully at the lens.

Agnes Tachyon: "Greetings, dear viewers! Welcome to today's live lecture. Our topic for this session is... the proper, optimal fertilization of an Umamusume!"

Agnes Tachyon: "You see, a very generous, wealthy benefactor offered to fully finance my research project on the outer limits of speed... under one simple condition: that I allow him to fuck me thoroughly on camera. A minor concession for the advancement of science! My wonderful spouse is waiting for me at home, and I'm certain they will be immensely proud of me when I unveil my next groundbreaking discovery."

Without missing a beat, Tachyon leans in and expertly licks the man's earlobe, whispering filthy words until he groans, bringing him to the very brink of climax. Right before he can ejaculate, her fingers clamp down tightly around the head of his cock, pinching it firmly and denying him.

Agnes Tachyon: "Observe closely, everyone. Right at this exact pinnacle of denial, the human male loses all cognitive reasoning... and devolves into a mindless, copulating beast."

The man's eyes snap, completely overcome with feral, uncontrollable lust. With a savage growl, he grabs her silver dress and rips it, forcing her down onto all fours on the bed. He shoves his raging, throbbing penis deep into her sopping pussy from behind, plowing her relentlessly like a rabbit in heat.

Man: "You fucking, greedy little science bitch! Take it!"

PLAP PLAP PLAP

Tachyon's eyes roll back, her horse ears pinning back as she screams in ecstasy, taking his heavy, unforgiving thrusts. The man erupts deep inside her, filling her womb with hot, thick semen, only to keep pounding her over and over, filling her again and again.

By the end of the broadcast, Tachyon has pulled her tattered silver dress back over her sweaty, cum-drenched body. She sits calmly next to the completely drained, exhausted man who lies flat on his back, gasping for air. Tachyon smiles at the camera as she gently strokes his limp shaft.

Agnes Tachyon: "And that, dear audience, is merely the beginning..."

Under her practiced, deft fingers, his penis begins to swell and harden once again.

Agnes Tachyon: "To watch the rest of this rigorous experimental procedure, please click the link below to access our premium, paid broadcast. Science awaits!"

After two weeks of deafening silence, Agnes Tachyon finally agreed to meet you. She stood outside a high-end restaurant, draped in the revealing silver dress and wearing stilettos. As you approach, she turns to you with a tired yet triumphant smirk.

Agnes Tachyon: "Ah, my dear guinea pig. I know you've been worried, but I've achieved a groundbreaking breakthrough! Not in speed, mind you... but in reproduction. I've developed a serum that enables an Umamusume to carry an immense number of offspring from multiple males simultaneously... and I naturally administered it to myself. I just have one last contract to fulfill tonight, and then I'll finally come home..."

Ngh... just one more session to secure complete, unlimited research funding...

Before she can finish, a large, wealthy-looking man strides out of the restaurant. Without a word, he roughly shoves Tachyon. She stumbles and falls forward, propping herself up on her hands and knees, bent over right on the pavement in front of the entrance.

Man: "Time to celebrate, you slutty thoroughbred!"

The man aggressively yanks up her silver skirt, slides her black thong to the side, and plunges his bare, throbbing penis deep into her sopping pussy. A flock of journalists and cameramen instantly surround them, their flashes blindingly snapping photos and broadcasting the entire scene live.

PLAP PLAP PLAP

Agnes Tachyon: "Aah...! Ngh...! Yes... the fertilization process...!"

The man shoves his hips wildly, pounding her from behind until he erupts, filling her womb to the brim with hot, thick semen. Yet, he doesn't pull out—he continues to violently ram his penis into her leaking, cum-stuffed hole. Several rich, drunk men peer out from the restaurant, laughing hysterically.

Restaurant Guest: "Hey! Don't use her all up! Save some for the rest of us, she's the main course tonight!"

The man pounding her glares at you, sneering as he thrusts relentlessly.

Man: "Hey, idiot! You're not on the guest list, so beat it!"

Agnes, flushed and trembling, looks up at you with tear-filled, pleasure-dazed eyes, her tail twitching erratically.

Agnes Tachyon: "Ngh... Ah...! Don't worry, my love... I'll return home... tomorrow... Everything will be... fine... I... I love you..."
