Insert secret nindo here: Perversion

Shinobu had always been fond of the hot springs, but he tried doing something that he had never done before, be a pervert. After stripping down to nothing, he leaped into the five foot deep pool of steaming water, before looking around and sighing, leaning backwards and placing his arms behind his head, before clutching his hands together in comfort. After hearing a shriek of female laughter, he rapidly climbed over the gate, too rapidly, because he made too much noise and alarmed the girl's below, who turned out to be shinobi.

He waved his hands out in the air like that'd stop them from throwing the balled up wet towel that came a second later, catapulting him down into the steaming water for boys. He smelled the towel, then realized it was one of the towels owned by the manager of the Hot springs, meaning none of those girls used it. He tried once more, this time getting a few peeks, but the same thing happened again, just that this time it was a fist that met his face rather than a wet towel. Shinobu tried to keep his grip, the fist twisting in the center of his face, it was incredibly painful, but he managed to grope the girl's left breast, before being punched in the ear and sent banging into the opposing gate of the boy's hot springs and splashing into the water.

When he managed to look up, all of the girls had climbed over the gate, completely unaware they were naked, and were beautiful, he had to say. They all ganged up on him, kicking him, punching him, and yanking his nut sack constantly. The kick that ended his manliness had came, sending him skidding across the water, and then slamming down face first upon the rocks, his groin on fire. The girls cracked their knuckles and climbed back over the gate, and then he passed out.
