Deep in the lower floors of Academia, weeping could be heard by any that would pass through the halls. This was not the weeping of some forlorn Duel Soldier, but rather the weeping of a young woman far from home and held captive within this "school of duelling". She had been there for days, not knowing how she ended up there or how she might ever make her escape. For the time being, she was forced to stay put and do as she was bid by her captors. They hadn't done anything horrible thus far, merely a bit of manhandling by some less-than-pleasant Duel Soldiers. But she assumed, soon enough, she'd find out just how horrible they really were.

Rin was her name, and Rin was far further from home than one might assume. She was from another dimension, one of four that existed in the whole wide multiverse. Not that she knew she was that far from home, in fact, she didn't have much clue where she was at all. Still, if there was one thing she did know it was that she was scared and wanted to go home. She wanted to go back to Yugo and the Friendship Cup, to her life. She was bored, lonely and scared of what the future held. She needed to get out of there, but how? Her question was about to be answered, however, as a Duel Soldier unlocked the door to the room she was being held in and stared her down with a mean expression.

"Follow me girly, the Doktor wants to see you," the unnamed Duel Soldier commanded, his face clearly showing he wasn't taking no for an answer.

"Where am I? Why did you bring me here?" Rin asked, her voice meek and desperate.

"No questions! Follow me," the Duel Soldier shouted, a scowl forming on his face.

The young woman sighed, quickly realizing she would get nothing from the man in front of her. As such, she silently nodded and got up from her chair. Leaving the room, she followed the Duel Solider silently. Looking at the man, she couldn't help but feel intimated as his presence loomed over her as he walked beside her. He was tall, and buff, with dark green spiked hair and a chiselled jawline and body. Worst of all was the burn mark over his eye, requiring him to wear an eye patch. Everything about him screamed killer, and the last thing she wanted to do was be on his bad side.

Rin was led through the halls of her place of captivity until eventually, she found herself outside a large pair of double doors. Opening up one of the doors, the Duel Soldier motioned for Rin to go inside. Reluctantly she complied and found herself inside a lab-type setting, with monitors and machines of unknown purpose lining the walls. In the middle of the room a skinny old man with sunken eyes, high cheekbones and long, grey hair sat at a table drinking a cup. Placing his tea down on the matching saucer sat atop the table, he turned to face the two of them with a creepy smile spreading across his face.

"I brought the girl as you asked Doktor," the Duel Soldier said respectfully, motioning to the girl next to him.

"Very well, leave us Barrett I have no further need of you," the man, simply identified as Doktor, replied dismissively. Barrett, the Duel Soldier, bowed in response.

"Of course, sorry for the intrusion," he said, before silently taking his leave and silently closing the door behind him.

"Rin, why don't you join me for a cup of tea?" the Doktor asked, his tone attempting something approximating kindness but with a clear edge of malice behind it.

Rin really didn't want to go any closer to the man, but really didn't feel like she had a choice. Slowly making her way over to the table, she reluctantly sat herself down at the table and accepted a cup of tea from the man. Smiling a creepy smile, the Doktor motioned her to take a sip, she did so and was relieved when she didn't feel any adverse effects from the drink. Placing the cup down on the saucer she was given, Rin merely stared meekly at the man, waiting for what he had to say. Seeing her emotions written all over her face, the Doktor's corrupt smile widened.

"I'm sure you're wondering why you were brought here," the Doktor began, leaning forward toward the girl. "While I am not able to explain the larger design for your captivity, I can explain why I brought you here today. Simply put, I have a proposition for you."

"A proposition?" Rin asked, not sure what to make of the man in front of her.

"Indeed. It's really quite simple," the Doktor explained, his false smile turning into a smirk. "We have a duel. If you win, I'll take you away from this place and you'll never see me or this place again. You can go back to your life and nobody here will be any the wiser that you're gone until you have long since slipped away.

"And if I lose?" Rin inquired.

"Then you have to obey me, for an…indefinite period of time," the Doktor told her, his grin widening as he did so.

Rin was extremely uncomfortable with the situation presented to her but also felt that her hands were tied. It wasn't as if she could say no. If she did, she'd either be coerced into compliance or taken back to her room and kept there until her true purpose for being in this place was revealed to her. At least this way, trap or not, it gave her the tiniest hope of escape should she actually manage to win. A determined look came across her face as she stared down the Doktor.

"Okay, let's duel," Rin said seriously.

"Excellent, I had Barrett pass your deck onto me before bringing you here. Here you are," the Doktor said, passing the deck over to her before beginning to shuffle his own.

Rin began to shuffle her own deck, not seeing anything wrong with any of the cards. That said, the cards were not the same as they were before she had been brought to Academia. She couldn't perceive this however due to the fact that despite not feeling anything wrong, there was something indeed changed inside her and Doktor knew it.

'Good, it's beginning to take effect. If the monsters inside her deck have already changed, that means the parasite has already taken hold,' Doktor thought to himself, laughing internally at his first victory.

The duel began as any would and Rin was all in at the beginning, the Doktor was even quite impressed at her skill in the game despite her subconsciously working with a deck she wasn't actually familiar with. However, he noticed her start to become sluggish and distracted as the parasite began to take its effects on her brain. Each successive turn became easier and easier to counter her plays.

Internally, Rin was trying her best to focus on the duel but her mind began to become foggy. Her eyes began to become glassy as she got lost in another world, her brain switching off from the duel taking place in front of her and practically going into autopilot as her mind was filled with images that she had seldom thought about before. Not even Yugo had inspired such strong feelings in her. Feeling of lust.

The woman could feel her nipples begin to ache and her pussy becoming wet, her entire body heating up as the images played out before her. In her mind's eye, she could see a man, a handsome man of the most stereotypical fashion. Tall, tanned, chiselled features and a muscular figure with eyes as blue as ice. She was mesmerised by him, enthralled by the vision before her, despite never having lusted after such men before.

Eventually, Rin was completely lost in her own little world. Inside her mind, she was making out with the handsome man on a king-sized, their tongues twirling in a lewd battle force dominance that the handsome man won easily. He pinned her down to the bed and made her feel small but secure and safe in a way only a real man could.

"Strip yourself," the handsome man commanded, his voice deep and confident.

Rin blushed and nodded shyly and slowly removed her white Turbo Duel jumpsuit. Laying naked before him, Rin couldn't help but cover her private parts by closing her legs and putting her arms over her breasts. The handsome man however would not be denied, not that she wanted to, and he quickly parted her legs and ran his hands up them until he reached her inner thighs. Reaching up with one arm, he grabbed one of her wrists and guided her hand down until she was touching her wet pussy.

"Touch yourself while you use your feet to get me off," the handsome man told her, making her blush turn an even deeper red.

The young green-haired girl didn't even know such a thing was what people did, but she didn't want to deny him so she did as she was told. The handsome man stripped himself of his black jeans and underwear, revealing the biggest and thickest cock Rin had ever seen. Not that she had seen many. Regardless, Rin did as she was bid and began to touch herself while using her feet to slowly jack off the handsome man, causing him to moan and groan in pleasure as she also did the same.

Rin had never felt this much pleasure in her life, and the mutual pleasure she was giving this handsome stranger was only turning her on more. So, needless to say, when the handsome man told her to stop, she was reluctant. However, when he grabbed her by the hips and flipped her onto her stomach, his large hands then firmly gripping her round ass she was both excited and curious as to what he'd get up to next. Her eyes widened when she very suddenly felt something long and wet touch her anus.

"What are you…?" Rin asked before an involuntary moan left her lips.

She didn't quite know what she was feeling, it felt strange and foreign but good at the same time. The handsome man was going to town on her ass, licking and prodding at her hole with an enthusiasm she was sure wouldn't exist in most other men. She could feel herself growing hotter, hornier and coming closer to what she thought might be an orgasm as he continued to work her backside. One thing was for sure, she was torn between him continuing to do what he was doing and doing something even better. Eventually, she made up her mind however and turned her head to the side so that she could be heard.

"I-I want to suck your cock," Rin admitted, causing the handsome man to stop.

"Very well," the handsome man said simply. Laying himself flat next to Rin, he looked her in the eye. "Get on top, put your legs over my face. We will do this together."

Not needing to be told twice, Rin turned herself around and swung her leg over the handsome man's head and with only a moment's hesitation, wrapped her lips around his cock. Despite her inexperience, Rin found herself taking to the challenge quite easily and found herself about to take about half his shaft including his head before her gag reflex began to kick in. Although, this was made a little harder by the fact that the handsome man had his face buried in her pussy and was licking and sucking on her clit causing her legs to almost give out due to the pleasure.

Rin tried her best to take as much of the handsome stranger's cock as she could, eventually forcing him past her gag reflex and into her throat, face fucking herself on his cock as he ate her out for all she was worth. Soon, she felt her lover throb and with a large pulse, he groaned as he unleashed several loads of semen directly into her throat. Rin instantly took herself off his cock and swallowed, just in time for one last load to shoot directly onto her face. At that moment, Rin's world turned upside down as with one final touch of her clit her orgasm was triggered and she cried out in absolute delight.

They stayed there, waiting for several moments as they allowed themselves to calm down. Once they did, Rin turned to her handsome lover and they both shared a look. He nodded his head down to his cock and she noticed that despite the gallon of semen he just shot, he was still hard. Understanding what he wanted, Rin decided to take the final plunge and climbed atop his lap and grabbed the head of his cock from beneath her. Lining it up with her well-lubed cunt, she slid him inside her with one swift motion.

"Oh god!" Rin cried out as she felt her lover fill her for the first time.

She began to ride him as fast and hard as she could, her body quickly becoming addicted to the pleasure he was able to give her. The old Rin, sweet and kind, began to melt away replaced by a sex-addicted servant who wished for nothing more than to please the man below her. Rin was lost, completely subsumed by the shocks of pleasure shooting through her with every sway of her hips. There was no coming back from this, and Rin didn't particularly care to either. Before long, she could feel another orgasm approaching, and she worked harder to get to it as quickly as possible.

As lost as she was, Rin didn't notice as the visage of the handsome man melted away and was replaced by the thin and gangly visage of the Doktor, laying naked below her as she now rode his cock instead of the mysterious stranger she'd been with not second ago. By this point however, she was a mess of pure eroticism and cared little for who or what was bringing her to this point. Finally, her eyes widened as another orgasm, even more powerful than the first shoot through her body making the Doktor below her orgasm with her.

The orgasm lasted several moments, but as she began to come down from it the mental images began to fade away just in time to see the still fully dressed Doktor take her life points down to 0, meaning she had lost the duel. As her mind cleared, it quickly became obvious to Rin what that meant.

"You lose. You know the conditions, now you will obey me for as long as I desire," the Doktor declared. Rin hesitated for a moment, but then a smile spread across her face and she nodded.

"Yes, of course, Doktor," Rin agreed, standing up from the chair she had been sitting in.

"Good, now do as your master bids you and service me with your mouth," the Doktor ordered, pushing down his trousers and underwear to reveal his cock.

"Right away," Rin complied, her tone neutral and compliant.

The green-haired girl got down on her knees in front of the Doktor and without hesitation began to suck him off with all the enthusiasm she had shown in her daydreams. Internally, the Doktor relished his great victory. However, there was still work to be done.

Looking across the room to one of his many monitors, a smirk spread on his face as the form of another girl appeared on it. A girl very close to Rin, though she didn't yet know it.

The girl known as Ruri would be next to fall to his will.
