Seiko ambushes her

Seiko stayed under the desk, waiting for Ruruka to get closer.

Soon enough, Ruruka was checking the cabinet next to Seiko's desk. Ruruka was facing the other way and had no idea that Seiko was right behind her.

Carefully, Seiko crawled out from under the desk, slowly reached out to the waistband of Ruruka's skirt and when the time was right, she yanked them down as hard as she could, pulling down her underwear in the process.

"Ahhh!" The now bottomless Ruruka was in shock, the entire bottom half of her clothing was around her ankles and when she tried to move, her legs got caught up in the clothing around her feet and she fell over.

Before she could even process what just happened, Seiko crawled on top of Ruruka and pinned her down.

"Hey, Ruruka!" Seiko called out from on top of Ruruka, their faces only a few inches apart.

"S-Seiko, what's up?" Ruruka asked in an attempt to play innocent.

"Oh, nothing, I just got stabbed in the back by my friend!" Seiko yelled out

"C-Can't we talk about this?" Ruruka asked, trying to worm her way out of any form of punishment but Seiko wasn't having any of it.

Seiko moved her arm towards the bottom of Ruruka's shirt and pulled up with all her might, causing the shirt to get caught around Ruruka's head, making her unable to see what Seiko's next move would be.

Rather than continuing to pull at Ruruka's shirt, Seiko used the opportunity to unhook Ruruka's bra before lifting it up and finally pulling off her shirt and bra, leaving Ruruka naked aside from her socks and shoes.

While laying out the floor, Ruruka quickly covers up her boobs and bend her legs in a way that covered her ass and pussy "Okay, Okay, we're even." She said in a panic, not wanting anything else to happen to her.

Seiko pushed Ruruka over again, pinning her arms above her head and her legs as far they would stretch, preventing Ruruka from being able to cover herself. She could feel her breasts and waist rub against Seiko's.

"We're not even close to being even!" Seiko glared right in Ruruka's soul with all the malice in the world.
