Unfortunately, yes.

Yukari was giggling mischievously as she continued to play with a doll, with some of Kurumu's hair in it, and she moved it in a manner that controlled one of Kurumu's hands, making it pull up Kurumu's top and bra, exposing her boobs to Tsukane and Moka, and then said hand began to roughly play with said tits while the other hand kept playing with her pussy.

"Make it stop Tsukane!" Kurumu whined through her pleasured moans.

"I dunno..." Tsukane replied, watching for the moment, grinning slightly. "It's pretty harmless for the moment at least, we're the only ones here... And Gin said he'd be late today, so we're safe. I think we can enjoy this for the moment..."

Kurumu brightened slightly, and stopped trying to resist the spell, her movements becoming a bit smoother. "Tsukane, I do see your point... but if we don't nip this in the bud, Yukari could do this in a more compromising scenario and get Kurumu in real trouble..." Moka pointed out.

"...good point," Tsukane replied, heading for the window, and throwing it open. "Yukari-chan, whatever you're doing to Kurumu, please stop," he said.

"Ah!" she yelped, realizing she had been caught. "Oh, Tsukane-kun!" she chuckled nervously, dropping the doll.

Crash! "Ack!!!" Kurumu yelped as she hit the floor, her body falling down onto it against her will, imitating the doll's motions.

Yukari of course burst out laughing at the sight, even if she hadn't meant to do that, she wasn't complaining about the results. Moka walked over to the window with Tsukane, and was about to talk to Yukari about her actions in a polite manner, before Kurumu shot over, now angry, and pushed Moka a little aside. "Alright, that tears it you little twerp!" she growled.

"Kurumu!" Moka protested, but was summarily ignored as Kurumu plowed on.

"You think you're so much better than me because of your grades, don't you?!" she snarled. "You think that entitles you to decide that I'm not worthy of being friends with Tsukane and Moka? Did it ever cross your mind that that's not your choice to make!? If you're just going to act like a total brat and be a nuisance to us, then get lost!"

Yukari flinched back, as if physically struck by Kurumu's words. 'I'm... A nuisance even to those two?' she thought in despair.

"Kurumu, that's too much!" Tsukane protested.

"No, it's fine, I don't mind," Yukari replied in a hollow tone as she stared at the ground. "I haven't needed friends all my life, why should I start now?" She then ran off.

Kurumu flinched back as Moka and Tsukane turned stink eyes towards her. "...we're going to have to go after her, aren't we?" Kurumu sighed, retrieving her panties as she spoke, and putting them back on, not caring she was doing it in front of the two.

"Yes, and you're going to apologize," Moka huffed as Tsukane curiously reached out of the window to grab the doll Yukari had dropped.

"Fine, let's go..." Kurumu sighed, heading for the door, before freezing and pulling up her skirt, and leaning forward, showing her panty clad ass. "Damn it, she's at it again!" she growled.

"Actually, that's me," Tsukane grinned a bit, holding and manipulating the doll. "Was just curious to see if only she could use it once she made it."

"Oh, well that's okay then!" Kurumu changed her tune on a dime as she grinned back at Tsukane.

"But enough messing around, let's go find Yukari," Tsukane replied, putting the doll in his pocket.
