Teaching Lessons: Part I

Tk was a fairly smart kid but recently no one would be able to recognize it. He was failing out of high school and doing so with an insubordinate attitude.

Two months ago he moved for the twelfth time in his life and began his third high school. He'd stayed at his previous school for over a year and had finally made steady friends for the first time in his life. Thereby, when his mom told him he was moving his happy demeanor switched dramatically to resentment.

Aside from resentment, Tk had given up on the world. He no longer saw any importance in either good grades, homework, or making friends. When he began his new school as a senior he didn't talk to anyone. Everyone had been nice, especially the girls who were fascinated by his beautiful blond hair and blue eyes, but he had scared them away with a glare. The only time he did talk was for a quick quip at a teacher that usually led to detention.

"Tk, I got a call from the school again." Tk's mother, Nancy, yelled while entering his room in a fury, "They said you are outwardly belligerent and are failing all your classes."

"I'm not belligerent, I'm obstinate. I refuse to do what those idiots tell me." Tk said while lounging on his bed and barely looking up to see his mother.

"What's wrong with you? Where is my baby boy?" Nancy said with tears appearing at the brims of her eyes. She couldn't understand how her son had suddenly rebelled so much.

"Nothing is wrong with me, I'm simply not a baby anymore." Tk said cockily.

"I don't know how to deal with you." Nancy left Tk's room with a sniffle.

"Tk, get up!" Tk opened his eyes and saw his Irish twin on the other side of his room. He blinked.

"Matt, what are you doing here?" Tk asked groggily. Matt was Tk's older brother by three years and yet they were nearly identical in looks. The only real difference was the facial hair and Tk's extra inch of height - something Matt openly resented.

"Mom called." Matt threw some clothes at Tk. "I'm supposed to talk to you."

"Oh," Tk sneered, "good luck."

"Come on, get dressed. I'm buying you breakfast." Matt tried to encourage his brother to move. Tk sighed but consented.

The brothers went to a nearby diner and happily enjoyed the first half of the meal with meaningless chitchat. However, Matt eventually ruined the mood.

"Why aren't you trying in school - you're a genius?"

"I'm not a genius!" Tk said harshly. The title of genius was something Tk never wanted because it involved too many high expectations and pressures.

"Just answer the question." Matt said with a smidgen of older brother authority.

"I don't find it worth my while anymore." Tk answered.

"That's stupid," Matt replied, "if you give up on school what are you going to do with the rest of your life?"

"I don't know," Tk shrugged, "I don't care."

"Mom, Dad, and I care." Tk snorted but Matt continued, "We want you to succeed. One of my friends has a little sister in your grade. She's agreed to tutor you."

"What?" Tk said with another snort.

"I know you don't need a tutor," Matt explained, "but she's going to be monitoring you to make sure you start doing work."

"And you really think she'll help change me?" Tk sighed. He honestly didn't understand his brother's thinking.

"It's worth a try."

"Whatever." Tk shrugged and continued to eat his breakfast while ignoring his brother.

Tk met Kari Kamiya after school on the following Monday. Despite their same grade they shared no classes and Tk didn't recognize her - and he would definitely remember her. Kari was absolutely beautiful. She had long legs, flawless skin, and luscious lips. Both her eyes and hair were colored dark chocolate and uncommonly shiny. Yet, despite her beauty Tk did not change his attitude.

Tk quickly learned that Kari was very innocent and studious. He found this amusing and loved to annoy her by not doing work; the way her face would scrunch up in disappointment was cute. However, after two weeks he began to get bored with her frustration and decided to try something new.

"Kari, I have a proposition." He began in a sly voice.

"What is it?" She said with an exhausted sigh.

"I'll answer those English prompts in exchange for a gift."

"What kind of gift?" Kari questioned uneasily. She didn't quite understand Tk or what his sudden interest in finally doing homework was about.

"A kiss."

"A kiss?" Kari asked with her eyebrows raising.

"Yup." Tk said smugly. Kari was thinking over his proposition thoughtfully and squirmed in her seat anxiously. Tk couldn't help but smile as her silky leg accidentally nudged his own.

"You promise you'll do them?" She asked.

"Yes. It's a pretty sweet deal. In exchange for one itty bitty kiss you'll finally be able to report progress to my mother and make all that money she's paying you worth something."

Kari thought a moment longer and then finally agreed, "Fine, just a kiss."

"Here's a preview." Tk smiled as he leaned over and kissed Kari on the cheek. As she froze in shock with a blush on her cheeks he picked up his stuff and walked away.

The next morning at school Tk walked up to Kari's locker and waved a piece of paper in front of her face.

"What is it?" Kari asked surprised.

"The English prompts." Tk answered.

"But they weren't due until tomorrow." Kari glanced over the page with even more surprise.

"I had a midnight moment of enlightenment."

Kari smiled happily, "Good job. You should go turn it in right away."

"I will," Tk smiled, "but first my prize." Kari looked around the crowded hallway anxiously and Tk gave an amused laugh. He grabbed her elbow and lead her further down the hallway before suddenly opening a door to a janitor's closet and pushing her in. Once the door shut behind them Tk asked, "Better?"

Kari nodded her head embarrassingly, "Yeah."

Tk waited a few moments for Kari to give him his kiss but when he realized she was still way to shy to do it he leaned in and touched his lips to hers. The kiss was soft and delicate but also lit a fire underneath both their skin.

"Yumm, strawberry lipgloss." Tk said as he pulled away. Kari's cheeks flamed red. "I'll give a moment to cool down." Tk left Kari in the janitor's closet and went to class.

"What homework have you got today?" Kari asked after school a few days after the incident. She and Tk hadn't mentioned the kiss and Tk had returned to his normal, effortless self.

He shrugged, "I don't know."

"What about calculus? You have a worksheet nearly every day."

"I hate calculus. It's sooo boring." Tk whined.

"But if you don't do at least one assignment soon you won't be able to lift your grade." Kari tried to persuade him but he didn't seem to care. However, after a few seconds a sly smile came across his face and Kari began to get nervous.

"Another prize might help motivate me." Tk couldn't deny that he had thought of Kari's lips on his own for the last few days and couldn't wait for it to happen again. Yet, he knew he would have to be patient in order to convince her.

"Okay." Kari said meekly. "A kiss."

"Nah," Tk leaned back into his chair, "I feel like appreciating my heritage."

"Which is?" Kari asked unsure.

"French." Kari still looked confused and Tk clarified, "French kissing."

"Oooh." Kari said with her eyes widening.

"Never had a french kiss before?" Tk teased, "Don't worry, I'll teach you everything you need to know." Before Kari said another word Tk stood up with his backpack and walked away.

"Wait, I didn't agree!" Kari called after him. Tk didn't even turn around but merely gave her a small wave of his hand.

The following day Tk waited by Kari's locker after school and greeted her slyly when she arrived, "The teacher was so surprised I thought he might have a heart attack." Tk leaned forward but Kari pushed him away looking down the hallway again. "Everyone already left." Tk said before leaning in once more and connecting with Kari's lips. His tongue swept the outer then inner edge of Kari's lower lip and her mouth parted automatically. Tk explored the caverns of her mouth and wrestled with Kari's tongue while pressing their bodies closer together. He pushed her against the lockers and Kari's hands unconsciously moved to feel Tk's golden hair.

When Tk finally backed away to let them both breath he had a giddy smile on his face. Kari also looked very satisfied with the kiss and longing for more. Tk teased her, "I have a chemistry report due next week. I wonder what my prize will be." Kari was at a loss for words. "We'll talk about it tomorrow."

Tk left Kari and headed home.

Kari wasn't easily able to forget the feeling of Tk's kisses and the next day blushed when he walked into the library to meet her to study. She was also embarrassed about what he would ask for next.

Tk could see Kari's anxiety and enjoyed watching her squirm until the end of the hour they were supposed to be studying and working on homework that day. When he finally spoke Kari got even more anxious, "I know what I want."

"What?" Kari asked softly. Tk didn't speak his answer but rather let his eyes wander to it. They went from her lips, down the caress of her neck, and rested on her breasts. "What!" Kari said in shock.

"Has no one ever seen them before?" Tk saw Kari's innocent blush and couldn't help but tease her more, "That's a shame. I imagine they're quite beautiful."

"Stop it." Kari said embarrassed.

"Not until you agree." Tk bargained. Kari didn't answer right away so he continued, "Your nipples are probably rosy pink petals floating on mountains of milky..."

"Stop it," Kari was absolutely crimson, "I agree."

"The lab is due on Monday, I hope you think about me all weekend." He left towards home.

Tk's wish was fulfilled in that Kari did think about him all weekend. Sometimes she would curse herself for letting him convince her to do such embarrassing things, but when she remembered their kisses she couldn't help but want more. She didn't quite understand her own feelings but she knew she wanted to touch him again and vice versa.

Tk was in a similar situation. He wrote his lab report gleefully as he thought about his prize and the softness of Kari's skin. He also felt excitement about seeing what no man had ever seen before. These thoughts kept him happy nearly the entire weekend so that when his mother checked in on him he didn't even fight with her.
