Streaking

Ryuko was standing in an alley at 2 a.m. dressed in her normal school outfit, tapping her foot impatiently awaiting her sister.

"How could I let this happen, I get the whole sister bonding thing but this dare is to damn much."

Ryuko kept looking around waiting for Satsuki to arrive with a blush on her face, her awareness of the task ahead of her was making her anxious. She had so many mixed emotions of fear, embarassment, rage these swirled in her head as she thought about what might happen.

"Being her slave for a week doesnt even seem right compared to this, why dont I just deny i-"

"Too late for that!"

Ryukos heart nearly shot out of her chest, Satsuki had arrived basically out of nowhere wearing her elite uniform.

"What the hell Satsuki, you nearly killed me by doing that!"

"Hehe, sorry I thought id get your energy going before your run."

Ryuko's face was flushed after her fear faded and remembered why she was there.

"So no way out huh?" Ryuko asked

"Oh my, is the fearless Matoi backing down from a challenge?"

"N-no...its just embarrassing is all ok?"

"How, the whole city has already seen you naked."

"Yeah but everyone was naked then, so it was a little less humiliating."

"Either way, its this or you become my butler for a week."

Satsuki placed her hand on Ryuko's shoulder.

"Look itll be fine ok, you just have to run to the academy and back, its just an innocent little dare is all, no one will know and everyones asleep anyway."

Satsuki's words helped Ryuko muster up some courage to conquer her embarassment, the two had become fairly close since their final battle and the two enjoyed that.

Ryuko raised her head to look at her sister in the eyes.

" Just there and back only right, no catch?" Ryuko began unbuttoning her shirt.

"No catch, just run naked there and back to this alley just dont cover yourself or steal clothes during your run."

"Or what?" Ryuko had unclipped her bra and let it and her shirt hit the ground.

"Then you'll be my butler for a month, and maybe...ill make you come to school completely naked." Satsuki teased.

"You bastard." Ryuko had pulled down her skirt and panties afterwords taking off her socks and shoes.

"Those are the rules, maybe next time youll be a bit better at arm wrestling." Satsuki continued to tease as she giggled at Ryuko's frustration leaking through her face as she stood bare arms crossed, her pale nude form illuminated by the moon striking the alley.

"Quit your giggling, im about to go..." Ryuko turned her back to Satsuki inorder to face the opening of the alleyway peering out to make sure she was alone. "Are my clothes gonna be here when I get back?"

"Of course." Satsuki replied.

"Ok...well here it goes I guess," Ryuko stepped out of the alley and began her run.

Satsuki had stepped out for a second to wave her sis good luck, with Ryuko turning to give her the thumbs up as her lips quivered and she turned back and started jogging.

Little did she know behind Satsuki's back was her left arm holding a katana, and her index and middle fingers crossed. Satsuki stepped back into the alley, shredding Ryuko's clothes with her sword giggling and then pulled out her phone and dialed a number.

"Get things in place, I set up the plan." Satsuki closed the phone and began to walk away.
