Here's a short SasuSaku one shot. Enjoy.
I do not own Naruto.
Sakura dragged him down the hall towards the girl's restroom to prove to Sasuke once and for all about her pink hair.
Many times she has told Sasuke that her hair is natural and real. Many times Sasuke told her that it was dyed and fake. There was no way could Sakura be born with pink hair.
Pushing the door open, they both walked inside and Sakura told any girl that was in there to leave. The two girls that were in there left but not before taking a good look at him. Once they were gone, Sakura locked the door and took several steps towards the wall and faced him.
"You said that I dyed my hair pink, Sasuke?"
Sakura reached under her skirt and pulled her panties down to her ankles. Sasuke watched as she grabbed the edge of her skirt.
"Guess again!"
Sakura lifted her skirt revealing her lower self to Sasuke. He had receive a good view on her lady part. He saw how it was nicely trimmed and, true to her word, were pink. Sakura then released her hold and bent down to pull up her panties.
"That's what you get for not believing me. Now will you please excuse me I have to get to class."
Sakura walked past Sasuke to leave. Just as she was about to reach for the handle, Sasuke snatched her wrist and turned Sakura to face him. He leaned down to whisper into her ear.
"I need to verify that it is, indeed, your actual hair color, Sa-ku-ra."
Sasuke then lifted Sakura by the waist and sat her on top of the counter. Ignoring her screams, he reached under Sakura's skirt and removed her panties.
"What are you doing, Sasuke?!"
"This is what you get for flashing me."
Getting down on his knees, Sasuke's head disappeared under her skirt and proceeded to give Sakura a tongue pleasing which made her scream out his name at first contact.
"Sasuke!"
For the rest of the period, Sasuke spend the entire time not only checking out her hair color, but also screwing the daylights out of Sakura.
