Not punish

"I won't punish you," Sasuke said. "But discard those panties now!"

"Yes, Sasuke-Sensai."

Shizuka tossed her panties aside, and Sasuke heard some struggling in the bushes.

Samui emereged with Kurenai restrained.

"Sasuke," Kurenai growled as she struggled against Samui's iron grip. "What the hell have you done?"

Sasuke said nothing, simply pausing Kurenai.

"And another one bites the dust," he snickered.

He decided to incorporate Kurenai into Shizuka's next lesson.
