The two combatants walked up to either side of the arena.
"In this corner, one of those special Sonic characters that helped bring about many new furries, alternatively an interdenominational princess or an apocalyptic time travel based on the continuity you go by, Blaze the Cat!" Blaze stepped into the arena, giving a polite bow.
"And in this corner, the former X-men turned bad guy, mutant shape-shifter extraordinaire and who doesn't take anyone's shit, Mystique!" Mystique stepped into the arena, giving a confident smile.
"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, Blaze readying her inner heat, and Mystique merely smiling, already seeming to know what she'd do.
"If the combatants are set," there was a pause, during which Blaze's eyes flashed with heat filled lust, controlled of course, and Mystique's skin began to twitch slightly, prepared to shift form, "begin!"
Blaze rushed forward. So long as she kept her mind focused, her heat would actually serve to stall her climax, giving her more energy as she and Mystique went at it. It was a good plan, one that backfired immediately.
Mystique grinned, changing her form into that of Silver the Hedgehog. Blaze hadn't expected this. This being a female sex combat league, Blaze had been prepared for Mystique to change into any number of females from her world, but this caught her off guard.
And seeing Mystique-Silver's cock get hard at the sight of her made Blaze lose control of the heat. The heat spread throughout the cat's body, seeming to develop a mind of its own as it began burning at her skin, making her sweat.
"Oh Blaze~" Mystique purred in Silver's voice, "been awhile since we've had some fun hasn't it?"
It had, it really had. It's been weeks since she'd left for the Tournament, and she hadn't seen Silver since. The heat practically started speaking to her, telling Blaze to do it, that she needed it, that she'd feel better afterwards.
And Blaze listened.
Blaze let her fire spread across her body, burning off her clothes and leaving her naked before Mystique.
"And Blaze has willing removed her clothes! Looks like lust has completely taken her over!"
It had. Blaze knew it and didn't care. That was the problem with Blaze's particular combination of power and species, they fed into each other, creating an endless loop of power and lust. When channeled she could use it wield incredible fire powers or last for hour on end in bed without cumming once; but she was only in control so long as she was with her mate and getting regular time in bed. Like this, she imprisoned by her lust and was slowly losing the will to care.
Blaze pounced, mounting Mystique. She knew it wasn't Silver, but she didn't care, she couldn't take it anymore.
Mystique grinned, holding Blaze's hips as the cat rode her hard, and began thrusting up into Blaze as she did. Mystique could've easily formed herself a member that worked, felt pleasure, and came like a normal one, but it was much easier to win this way, which one that she couldn't feel.
As Blaze kept going, slowly reaching her climax, Mystique felt nothing. There'd be time for that later. Mystique was impressed though, as Blaze lasted almost n hour before she came.
"Blaze has reached climax! Mystique is the winner!"
"Fuck my ass goddammit!" Blaze shouted, getting on her fours. Mystique grinned, making a small adjustment to her form so she could feel and cum from her cock before she rammed into Blaze, reaching over to grope the horny princess/time traveler's chest.
"Well then, looks like someone can only go so long without a good fuck from their lover. Next up is Azula vs Jinx! Will the fire princess be able to handle the HIVE dropout? Or will the ruler of misfortune make the fire nation daughter slip up? Find out in the next round of Yuri Tournament!"
