Pranking Sasuko

((DISCLAIMER: I got the idea a while back from 'Sigma vs Omega' flash. All right belong to the person who made it))

Today was one of those days where Naruko wanted to pull a prank. Her target for this prank was none other than that slut Sasuko.

During Sasuko's training Naruko sneaked to Sasuko's gym bag. She opened her bag and grabbed Sasuko's bottle of water. She quickly opened it. "Hehe, this will teach that skank a lesson.", she giggled as she dumped some cleared powder into the bottle. She then quickly closed the bottle and put it back into the bag and hid in the nearby tree, so that she could view her master plan come into fruition.

Sasuko came around a minute later, sweat-covered from training. "Man, I need a drink.", she said to herself as she opened her bag. She took out the bottle and took a big sip.

Yes, it won't be long now!, Naruko thought, covering her mouth as she tried not to laugh out loud.
