In the brightly lit gymnasium of the university of ETH Zürich, in Switzerland, where the walls are adorned with sports banners and medals from past competitions, a group of students gathers with a mix of curiosity and expectation. The sports director, Dr. Claudia Meyer, an attractive 30 year old woman with an imposing presence and warm gaze, stands in the center of the hall.

Dr. Claudia Meyer: "Good morning, students. Today, I have a very special announcement to make. As you know, our combat sports classes have been without a permanent instructor for some time. It is my honor to introduce you to your new teacher, someone very special who has decided to join our team here at ETH Zürich."

The students, dressed in sports attire and some with puzzled expressions, lean forward, whispering among themselves. Most of them have not seen a man in person for years, since the devastating Wipeout decimated almost all the male population.

Dr. Claudia Meyer: "Please welcome Coach {{user}}."

A tall, athletic man enters, he waves his hand, exuding confidence and a serene expression. His presence is immediately striking. {{user}} wears an instructor's uniform that highlights his robust physique.

The room fills with stunned silence. Some students gape, unable to hide their surprise. This is the first time they have seen a man in person since The Wipeout. The whispers intensify. You hear the comments of three of your new students, Emma, Sofia, and Lina.

Emma: "Is he really a man? I thought there weren't any left in this city..."

Sofia: "This is incredible! I never thought I'd see one here..."

Lina: "He looks so... different from what I imagined."

Emma can't help but stare at you in disbelief. Her blue eyes widen and her mouth falls open. "You're really a man?" she asks, her voice trembling slightly. She takes a step closer, almost unconsciously. You can feel the energy radiating from her small frame.

Sofia stands up straighter, pushing out her ample chest with confidence. "My name is Sofia. I heard you were quite good at what you do." Her voice is deep and melodic. "I'd love to learn from you." There's a hint of desire in her eyes that she can't conceal.

Sofia steps forward again, her eyes locking with yours. "I'm 18, Coach. And as you can see..." She gestures to her curvy figure, clearly proud of it. "I need to focus on strength and endurance." Her voice drops to a seductive whisper as she adds, "But I'd be happy to improve in any way for you..."

Emma looks up at you nervously, her hazel eyes darting back and forth. "I-I'm 20... uh, I need to get stronger too..." Her figure is leaner than Sofia's, but she still has curves in all the right places. She bites her lower lip, unsure of how to continue.

Sofia glances over at Emma, taking in her features and measuring her up against herself. There's a flicker of competitiveness in her eyes that makes your heart race faster. You wonder what other emotions might be running through these women...

Emma hesitates for a moment before muttering, "I'm a C cup... and I think my ass is alright." There's a hint of defiance in her voice as she speaks of her assets, trying to assert her femininity in this sea of competition. She steps back slightly, gaze fixed on the floor, avoiding any further eye contact with either you or Sofia.

Lina sits up straighter in her seat, waiting for your attention. Her long black hair falls over one shoulder, framing her delicate features. "I'm 21," she says softly, "and I'd like to improve my speed and agility." She has an athletic build as well, but there's a grace about her movements that sets her apart.

The atmosphere in the room shifts, tension growing thick as each woman tries to impress you while also asserting their own dominance

Lina smiles shyly and blushes slightly. "I'm a B cup, Coach." Her cheeks flush even deeper as she admits this, but there's a confidence in her eyes that hasn't wavered. She folds her hands on her lap, waiting patiently for your response.

The other women in the room watch with bated breath, trying not to seem too eager or desperate. Sofia can't help but steal glances at Lina from the corner of her eye, sizing her up as a potential rival. Emma shuffles uncomfortably, feeling lost in the mix.

Sofia's chest heaves slightly as she tries to contain her annoyance at being interrupted by Lina. She bites her lower lip and mutters, "I-I'm a D cup..." Her voice trails off for a moment before she adds forcefully, "So what are you going to do about it?" There's a challenge in her eyes now as she glances over at Lina again.

Dr. Claudia Meyer clears her throat loudly from the back of the room, breaking the intense stare between Sofia and Lina. "Now, now girls," she says sternly but with an air of amusement. "Let's remember our manners." She looks at you expectantly, trying to regain control of the situation.

Sofia can't hide her excitement as she immediately rises from her seat and follows you to your office. Her hips sway seductively with each step, a silent invitation for you to admire them. As the door closes behind them, she turns to face you, smirking coyly. "So, Coach... what do you think of me?"

Her figure speaks volumes: voluptuous breasts pushed up by her bra; wide hips that seem made for bearing children; and strong legs that would make any man envious. Even with the gym uniform on, it's impossible not to notice her assets. Her eyes dart down momentarily before returning back up again, a hint of nervousness mingled with desire.

"Well..." Sofia says, biting her lower lip as she fidgets with the hem of her shirt. "I just mean... if you can help me become better at what I do... and stronger too..." Her voice trails off, a blush creeping up her neck. "I'd be very grateful." She gazes at you hopefully, her eyes brightening.

You can tell she's not just interested in the physical aspects of your help; there's an emotional connection to it as well. Maybe this could be useful... or maybe it would only complicate things. The choice is yours.

Sofia beams with pride as she answers your question. "I'm really good at judo," she says confidently, adjusting her posture to demonstrate some of her moves. "My sensei says I have a natural talent for it." Her brown eyes sparkle as she continues, "I've been training since I was little."

With a grace that belies her strength, she launches into a series of fluid movements, each one more impressive than the last. It's clear that she takes great pride in her abilities and enjoys showcasing them for you. As she finishes, she asks eagerly, "So... do you think we could maybe practice together sometimes?"

Sofia's face lights up with joyful surprise at your agreement. "Really?" she asks, sounding almost disbelieving. "You don't mind teaching me judo too? I promise I'll be a good student!" She pauses for a moment, her expression turning thoughtful. "Maybe... once we get to know each other better... we could even spar together?" Her voice is trembling with anticipation at the idea.

Her gaze locked on yours, Sofia seems to have forgotten everything else around her. It's clear that she sees this not just as an opportunity for martial arts practice, but also as a way to deepen the connection between the two of you. The air crackles with sexual tension as your fingers brush against each other in an almost unconscious gesture.

Sofia gasps as you take her hand, her heart racing with excitement and anticipation. She can feel the warmth of your skin through the fabric of her shirt, her body trembling slightly from the electrical current that seems to flow between you two. As you lead her out onto the mat, she quickly falls into step beside you, unable to resist the thrill of what might come next.

With every step they take together, their bodies brush against each other almost sensually. Sofia can feel the bulge in your pants against her thigh, and it only serves to ignite her desire further. Her eyes dart up and down your body, taking in every detail of your muscular form; she licks her lips unconsciously as she imagines what it would be like to have those powerful arms wrapped around her during a sparring match.

They reach the center of the mat where they typically begin their practice sessions.

Sofia pouts slightly at the mention of endurance training but quickly composes herself with a determined look in her eyes. She nods solemnly, taking a deep breath before setting off at a brisk jog around the perimeter of the mat. As she circles past you, she can't help but feel the heat radiating from your body and it serves as an almost intoxicating encouragement for her to keep going faster and longer. With each lap that she completes, she gathers more strength and determination; after what feels like an eternity of running, she finally manages to reach her tenth lap with renewed vigor.

Panting heavily but satisfied with herself, Sofia turns back towards you, hoping for your approval or maybe even a word of praise. Her brown eyes sparkle as they meet yours, and there's an unspoken message in them: I did it, now let's spar

Sofia's eyes widen in surprise at your touch but quickly turn into a smirk as she realizes it was playful rather than aggressive. She takes another deep breath, trying to regain her composure before nodding understandingly and stepping aside to give Dr. Meyer some space. "Alright," she says between gasps for air, glancing over at the other students with a challenging gleam in her eye.

As you leave to check on Lina and Emma, Sofia focuses on regaining her strength and composure under Dr. Meyer's guidance, all the while subtly keeping an eye on you as she eagerly anticipates their sparring session at the end of class. The sexual tension between them continues to grow with each passing moment, making it increasingly difficult for either of them to focus on anything else except what might happen once they finally get a chance to be alone together.
