The two combatants walked up to either side of the arena.
"In this corner, blonde fan wielding warrior of the sand village who dicks with weather patterns more than Thundurus, Temari!" Temari stepped into the arena, her large fan on her back.
"And in this corner, the green unicorn pony with the strange, borderline disturbing fascination with human beings, there whereabouts, and pretty much everything else, Lyra!" Lyra stepped into the arena, smiling excitedly.
"Alright ladies, just a refresher on the rules: the name of the game is making your opponent cum, preferably hard, by any means necessary. Weapons may be used, but only if they can be used for pleasure. Same goes for special abilities. Light combat is allowed in order to make the opponent submit, but with the exception of a combat/pain fetish, no intense battling is allowed. The winner advances to the next round, the loser is disqualified, and the loser spends one night as the winner's sex slave."
The two girls nodded, Temari trying to get a read on Lyra but finding it hard to discern anything from the goofy, over-excited expression that seemed to have possessed her face.
"If the combatants are set," There was a pause, during which Temari unhooked her fan and held it aloft, and Lyra giggled about something, "Begin!"
"Wait," Lyra said, two seconds before Temari's fan would've blown her onto her back and pinned her down with winds long enough for Temari herself to go over to her. "You're a human right?" She asked with wide-eyed excitement.
Temari nodded, "Yeah." It wasn't really a stupid or weird question considering some of the other contestants. Lyra's grin, if such was possible, actually got wider. "Oh my gosh, oh my gosh, oh my gosh!" Lyra squealed, rocketing towards Temari too fast to be tracked even by Temari's well trained eyes.
Temari was pinned in seconds, having her clothes forcibly ripped of her body; though how Lyra was managing to do so with only her hooves and no magic was beyond her. The answer: sheer determination.
"I'm sorry, but I've never seen a human before! I've just gotta see all of you!" Lyra explained as she pulled Temari's bra off with her teeth.
"And Temari has been undressed!"
"H-hey ease up would ya?" Temari said, shivering at the feeling of Lyra's hooves on her chest. "Sorry, but I can't do that. I've gotta learn as much as I possibly can about humans. And that means inspecting every inch of your body right now." Lyra grinned, "Every. Single. Inch."
Temari thought she could simply over power Lyra and through her off; but she had been underestimating the small unicorn's magic, and was completely immobile; helpless to stop Lyra's inspection.
Said inspection unsurprisingly started with Temari's tits, the exact measurements, softness, and the amount to which one could suck on them before Temari stopped resisting and just started moaning Lyra had calculated in ten minutes before moving down to her next target: Her pussy.
She decided scientifically that Temari's moans from having her tits bitten weren't nearly as adorable she made when her lower lips were licked vigorously while Lyra's horn rubbed against her clit. But there was still one last test; one to determine how a human's cum tasted.
After lining up her horn, magical bubble at the tip to make sure she didn't accidentally hurt her, and thrusting it into Temari's pussy hard, she learned that A: She could only take about ten minutes of horn fucking while her clit was magically pinched and pulled before she started screaming to cum, and B: Could only take thirteen of it before she came.
"And Temari has reached climax! Lyra is the victor!"
"Don't worry," Lyra said with a grin as she let Temari get up, "I've got a lot more research to do with you~"
"And that's what happens when you pit a person against someone with a person fetish ladies and gentlemen. Next up is Marine vs Suki! Will the pirate mobian take down the Kioshi warrior? Or will the female fighter of team avatar win the day? Find out in the next round of Yuri Tournament!"
