, of course!

The sound of Rei's laughter and the shutter noise of her phone's camera filled Yuki's ears as she sat in petrified shock. Sprawled out on her bed naked, legs spread, vibrator still halfway inserted into her, Yuki knew this was already a nightmare.

"Rei, get the fuck out of my room!" Yuki finally shouted as her body caught up to her brain and she began to frantically move to cover herself. In doing so, she unwittingly offered the camera several obscene angles to capture more of her naked form before she finally wrapped her blanket around herself.

"Holy shit, Yuki, seriously. Holy shit." Rei said between laughs. "Mom and Dad are gonna lose their minds!"

Yuki's heart skipped a beat. "No!" she cried, the idea of her parents finding out about this terrifying her. "You can't tell them about this! Please, Rei, don't!"

Rei continued to laugh for a few moments, tapering off as she regained her composure. Sighing, she leaned on the door frame and fixed Yuki with an appraising look.

"Alright, tell you what. I'll keep this secret from Mom and Dad, and I'll even delete the pics from my phone. But only if you promise to do everything I say until they get back." Rei offered before quickly adding "And you can't tell them about any of this. You snitch on me, deal's off and I show them everything."

This was a bad idea. Yuki knew it was a bad idea to put herself at her big sister's mercy. But what choice did she have? Besides, their parents were coming back on Monday. It would just be a weekend of putting up with Rei's antics. She could survive that.

"Okay. Fine. You win." Yuki agreed meekly. "But you have to delete everything once they get home on Monday."

"Monday? Didn't you get their text?" Rei asked, her question answered by Yuki's confused look. "Check your phone, dumbass. There was some travel restriction imposed or something. They're gonna be gone for another two weeks. At least."

"Two weeks?! B-but I agreed thinking it was just the weekend, so... you've gotta let me off the hook after the weekend! It's not fair!"

Rei just smirked at Yuki's despair. "Bitch, since when have I cared about being fair? Now come on, your first task is to make me some breakfast."

Yuki grimaced. She knew there wasn't any arguing with Rei, at least not right now. Figuring she may as well get used to it, she snaked an arm out from her modesty blanket cocoon to reach for her discarded pajamas.

"Whoa, hey, did I say you could get dressed? I said go make me breakfast." Rei said. "Besides, it's just us, and you just showed me everything anyway. Come on, servant, hop to it!"

Yuki's cheeks burned with shame as she considered what Rei had in store for her.
