Not far, and Yukari decides on getting fucked.

Kurumu started to try to write after making sure no one was looking, but froze, unable to write. She had been about to write that Yukari would only be able to pick activities that would most embarrass her, but she couldn't make herself write it. '...darn, Master must have seen me trying to prank Yukari with the Sex Note coming...' she mentally pouted. Oh well, she could always come up with other ways to get even. She could concede defeat this time around.

Yukari meanwhile pored over Tsukane's homework. "Okay, seriously, who taught you long division in high school?" she teased him.

"...clearly someone who didn't know what they were doing?" Tsukane guessed.

"Bingo, or you weren't paying attention," Yukari huffed, correcting his formula. "See? Do it like that, and it's WAY easier..."

"Huh, you're right," Tsukane said, correcting a few answers himself.

"And you forgot to carry the 1 on question four," she added, and he quickly fixed that. This went on for about ten more minutes. "There you go, much better!" Yukari cheered at the end of it.

"Oh thank goodness, that just about fried my brain," Tsukane groaned, sitting back. "Now, I do believe I promised an activity with you."

"Well, I'd like you to go ahead and fuck me," she told him boldly.

"...well, that was fast," he grinned.
