The two combatants walked up to either side of the arena.
"In this corner, the magical maiden from the next world over, the emerald empress without a sense of humor or moral compass, the Enchantress!" The Enchantress floated into the arena, her expression serious and hard as stone.
"And in this corner, one of the fan favorite MLP background ponies, the walleyed wonder, the muffin mare, the mail pegasus formerly known as Derpy Hooves and my personal pick for the best of the ponies, Ditzy Doo!" Ditzy crash landed, getting up and dusting herself off before turning to the crowd and giving and excited 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."
Both girls nodded, Enchantress not paying much attention to Ditzy, who was trying to wave to her politely.
"If the combatants are set," There was a pause, during which the Enchantress finally turned to Ditzy, who's stance was stern and determined, hooves set, wings out and ready to take off, "Begin!"
Ditzy took off at her top speed, only to be halted in mid-air and pinned there with magic. The Enchantress flicked her wrist, sending several intense shock-waves of pleasure through Ditzy with her magic, making the mare cum so hard she fainted before being dropped back onto the ground.
"Huh...only now do I realize just how unbalanced this battle actually was. Oh well, at least Ditzy had a good time of it. Let's just hope the Enchantress is somewhat gentle with her. Well, that rather anti-climatically, pun only slightly intended, wrapped up the primarily rounds of Yuri Tournament! Next time we'll check in on the victors to see how they enjoyed their prizes and see what their plans are for the next rounds, and we'll see it all next time, on Yuri Tournament!"
"Now seriously, someone check and make sure Ditzy isn't in a coma."
