A small variety of things.

When Jaune looked over to Ruby, he noted that she had somehow managed to talk Weiss into pairing with her. Now they were both making out as their blazers hung open, exposing their small but perky chests, which were being rubbed together. "Hmmm!?" Weiss exclaimed through the kiss as her eyes widened. Jaune guessed that Ruby had added her tongue to the kiss, and he chuckled as he watched them grope each other's asses.

He then turned to see what Blake was doing. She had taken on full cat girl form, causing her tail to poke out from under her shirt, and was walking around in all fours, meowing and purring all the while. "Nyah," she said cutely, seeing him looking her way.

That only left Pyrrha in the class, and as he turned to her, he saw that she kept it simple. She had simply opened her blazer, exposing her breasts as she sat on the edge of her desk, holding her skirt up with both hands, showing she didn't have any panties on. Well, she had certainly come prepared. He certainly had to admire that. He met her gaze, and she was smiling softly at him, and she had quite a heavy blush on her cheeks.

"Alright girls, that's enough," Jaune called. Immediately, they stopped what they were doing, and returned to their seats. "All of you did well, I'll be marking your grade for that lesson. Whoever scores highest at the end of the day gets a reward. Ties are allowed of course."

"So what's our score for this round?" Yang asked, clearly hoping that her straight up humiliating herself willingly would get her high marks.

"Sorry Yang, that would be telling," he teased. "None of you will be knowing your scores until the end. Don't want anyone getting too comfortable with a large lead if they have it after all." Yang pouted as Jaune continued, "Now, onto Lesson 2!"
