The two combatants walked up to either side of the arena.
"In this corner, the bipolar beauty, alternatively a blue haired sweetheart with nurturing instincts or a blonde haired badass with warrior instincts (and an uncanny ability to pull firearms out of the fucking ether), Launch!" Launch, currently in her blue haired form, walked timidly into the arena.
"And in this corner, pony queen of of the wubs, known better by Equestians as DJ-Pon3, Vinyl Scratch!" Vinyl walked into the arena, bobbing her head to the music blaring from her headphones.
"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."
Both girls nodded, Launch waving politely to Vinyl, and Vinyl responding his a nod and a smile, though one or both of them may have been resulting from her music as opposed to the interaction with Launch.
"If the combatants are set," There was a pause, during which Launch straightened out her dress so it wouldn't be as easy to remove it and Vinyl lowered the volume on her headphones; slightly, "Begin!"
Neither moved for the first few moments, Launch because she wasn't quite sure what to do, Vinyl because she hadn't heard the call to begin. When it registered that the battle had started, Vinyl rushed over at Launch.
"Eep!" Was all Launch could say before she was pinned by Vinyl, who used her momentum and her magic to push her onto her back and hold her there. Vinyl's magic was overly powerful, but Launch wasn't exactly super strong, as Vinyl was able to hold her down as she lifted her dress up, using her horn to cut open Launch's panties, which send a shiver through her body as her horn, lit up with magic, made contact with the fabric, before plunging her tongue into Launch's slit.
Launch moaned, having very little endurance or pleasure tolerance while in this form. It didn't help that groupies and Octavia had acted as great tongue training for Vinyl. Wanted to pick up the pace, Vinyl decided to use her horn, dropping her magic hold on Launch so she could push her horn into her without making herself cum as a result.
Vinyl was right to assume that Launch couldn't have it in her struggle against her pleasuring, but that didn't mean Launch didn't have any tricks. Thinking fast, and knowing she was close, Launch reached up, plucking a hair from her head and rubbing it against her nose. After a few moments, Launch sneezed.
This had two effects, the first was stopping herself from cumming, which she would've mere seconds later if she hadn't sneezed and killed the building climax. The second was to switch gears, her hair becoming blonde.
Vinyl didn't even notice the chains, just heard a sneeze and ignored it. It was a few more moments before the realization that Launch wasn't moaning anymore. She tried to look up, only to have her head forced down as Launch mounted her horn aggressively. Realizing what was happening, Vinyl tried to force Launch off with magic, needing to get back and figure out how out handle the more dominant form of Launch...but Launch was still riding her horn when she did.
Pleasure shot through Vinyl's entire body, locking her into place and making any movement or focus, even just turning her magic off, impossible as her mind swam blissfully.
Launch began bucking her hips, forcing Vinyl's horn deeper inside her until it was at the base, making Vinyl cum hard, consequently letting out a small magic shock-wave. As Vinyl's magic was primarily audio based, the magic carried the sound of her cry as she came throughout the arena, letting it resonate through the area several times over.
"And Vinyl has reached climax! Launch is the victor!"
Vinyl got up shakily, Launch, now back to blue hair, smiling at her, "Did you have fun?" She asked, Vinyl smiling and nodding. "So did I. Don't worry, we can have some more for the rest of the night to!"
"Looks like aggression and peaceful natures keep each other in check quite nicely. Next up is Dawn vs Ty Lee! Will the Sinnoh coordinator show up the Fire Nation special enforcer? Or will the circus act turned soldier show Dawn the roped? Find out in the next round of Yuri Tournament!"
