"No Kakashi!" Kurenai shouted, hands moving in preparation for a debilitating genjutsu.
"You… can't… interfere!" Asuma added between grunts trying to hold his friend back.
"Must… go…!" Kakashi intoned as if in a trance. They'd seen all the Naruto clones transform into the buxom women and they'd all gasped in shock (for different reasons). But when the cat-fight started Kakashi couldn't control it any longer, he needed to be in that room!
Asuma and Kurenai were doing their best to hold him back, but he'd been a jōnin for longer than both of them combined and they were quickly losing the battle.
"Oh Youthful Rival!" Gai called out dramatically, "If you so desire the unyouthful scene in the examination room I will give you one here!"
There was a poof and in the place of Gai stood a voluptuous Gai. Bowl cut bangs with large pig-tails on the sides of… her?... head. Same wide eyes, but -her?- eyebrows were smaller and more shapely. It was the green spandex and orange leg warmers that really did the trick though.
"GAH!" Kakashi backed away into the corner with his eyes clenched tight like a caged animal and Kurenai and Asuma curled into the fetal position with their hands over their eyes. Kakashi started muttering under his breath about being forever scared and maybe giving up on Icha Icha if he could just remove the dreadful scene he'd just witnessed from his mind.
"Youthful Rival?" Gai-ete questioned, Kakashi's muttering increased tenfold as he started twitching.
