Sakura and Karin were both seated next to each other in algebra class, writing their personal answers on their respective school work. During class, Sakura would come accross a math problem she wasn't sure how to answer. So she would, every once in a while, look over Karin's paper and write down some of the answers, which Karin didn't mind.

One day, however, what Sakura was planing to do was much more naughty. While everyone was doing their school work, Sakura glanced over at Karin, who was more focused on her studies to even notice. With a snicker, Sakura slowly reached for Karin's skirt. Karin shot her eyes open when she felt something rub her genital through her panties.

The curly haired blonde slightly winced, struggling not to show signs of cringing as she sandwiched Sakura's hand between her thighs. She peeked an eye at Sakura and asked as softly as she could "S-Sakura...! *gasp* What... What on earth... Ngh...! Do you think... *gasp* you're doing...?!"

Sakura narrowed her eyes away with a smile, attempting to look innocent as she asked softly "Who, me...?"

"Who else... Could I be talking to... Right now...?!" Karin retorted. "You know we're not... Supposed to perform... Such activities... Around school grounds...!"

"If I'm doing what you think I'm doing, then maybe you should raise your hand and tataltail on me..." Sakura teased as she continued to pleasure Karin.

"Excuse me...?! As if I would fall for that...!" Karin then reached a hand for Sakura's crotch and said "Two can play at this game...!" Feeling Karin's fingers touch her vagina caused the short haired tomboy to cringe. "Let's see how you like it, you big dork...!"

Sakura winced as she glanced at Karin with a smile and said "I like it a lot... Actually..."

Though taken aback of Sakura's response, she regained her posture and said "Well, let's see if you can enjoy it without being noticed...!"

"Oh, you are on, Goldilocks...!" Said Sakura as she and Karin continued to have their fingers fidget around each other's vaginal area. Sakura moved her middle finger deeper in between the folds of Karin's genital. "I bet you are loving this, huh...?"

"I... Would be lying... If I said I am not...! But... I'm going to make you love this more...! So much, that you will moan louder than me...!" Karin decided to take it even further by moving past Sakura's panties.

Taking it as a challenge, Sakura moved her fingers under Karin's panties and inserted two of them inside her vagina, slowly and carefully pumping it in and out. "Not if I make you moan first...!"

They became lost in their competition of pleasuring each other, that they didn't notice the teacher spotting them behaving rather unusually as he shouts out "Ms. Kasugano and Ms. Kanzuki!" Sakura and Karin yelped and shot their eyes open as they looked at their teacher who was making a serious glare at them. They've also realized the other students looking at them with confused expression. "What on earth are you two doing over there?!"

Karin and Sakura narrowed their eyes at each other as Sakura said with a nervous smile "Uh... We're um... Scratching our crotches... Sir?" Hearing Sakura's excuse caused Karin to face palm herself in a dumbfounded manner.

Hope you've enjoyed the little prologue. Next chapter will have a whole lot more.
