The idea for this story came to me on a night I couldn't sleep. I chose to write it up and post it because I had previously done a poll. Kaito and Zero received the most votes. Enjoy.

Chapter 1: Mr. Takamiya's Rules

He was sleeping in class. There was no discernable reason why he should be losing sleep. There were no more night classes, so he didn't have to stay up patrolling. Perhaps he has insomnia, she thought. Her neck craned to look back at Zero she didn't notice the teacher approach.

In the middle of a lecture, there were several things that bothered Kaito. Everyone knew his rules. Rule #1 Face forward during lectures. He had finished writing important notes on the blackboard, turning around he saw one student whose gaze was directed elsewhere. Stepping toward the deviant, he grabbed her right cheek between his thumb and index fingers. With a grimace, he said, his face an inch away from her "Where are you looking, Ms. Wakaba?"

Caught by surprise, Yori stayed silent. Her eyes were large from the unexpected attention. She didn't know what to say, or do. She glanced surreptitiously to the left. "Sorry. I got distracted," she said, softly.

Kaito hadn't missed her quick sideways look. Releasing her face he straightened, a more pronounced frown on his face. Rule #2 No sleeping in class. Walking in front of an oblivious Zero, he picked up a neighboring student's book slamming it down next to him. The class flinched at the loud sound, but Zero only lifted his head briefly to rearrange his head comfortably in the crook of his arm then went back to napping. Annoyed, he headed back to his desk to pick up a pamphlet. Kaito rolled it up tightly, tapping it against his palm to test out its strength. In front of Zero once more, he hit him on the back. Zero's eyes opened, a glare directed at him.

"Mr. Kiryu, your snoring was distracting Ms. Wakaba from my interesting lectures," he said, in explanation. Turning to walk away, he added, "Both of you earned detention. Class dismissed."

Afterschool they waited for Kaito to tell them what he wanted them to do for detention. He let them stand in front of him awkwardly, expectantly. At least, it should have been that way except there was nothing awkward in their stances. Arms crossed, Zero looked bored. Wakaba stood straight, arms at her sides. Her whole demeanor was calm. How unpleasant, Yori. Can't you squirm a little under my scrutiny? An idea occurring to him, he brightened.

"Follow me," he said. It was such a cliché punishment, but he was going to reap its benefits. A scary aura of superiority, he said to Zero, "Drop and give me 50."

Yori didn't question it. She only took off her jacket, tying it around her waist. She hoped it covered her well enough and got into a push-up position. Kaito nearly sighed, shaking his head. He hadn't meant for Yori to do it too. He bit his tongue to keep from saying, 'not you.' Instead he observed them, as they waited for him to say start. Zero had the position perfectly, but Yori didn't. He pulled her forearms to be more apart. "Okay, start."

Zero finished right away and rested on his back, eyes shut. By her 3oth push-up Yori's arms were shaky. She was determined to complete the punishment. She decided at that moment to work out more when she had free time. Something about this situation made her feel self-conscious. Reaching the last push-up, she let herself fall on the warm, hard concrete. She vaguely thought as she stared at Zero reclining on the ground like he was lying upon a comfy couch how he managed to look relaxed. She couldn't complain, actually. It was wonderful to rest her tired arms, even if it was upon a dirty ground. She was looking forward to a soothing shower later.

"50 more push-ups," Takamiya said, cutting into Yori's thoughts.

Wincing at his words, she protested, lifting her upper body to rest on her elbows, "But—."

He interrupted, "You've earned another day of detention." Kaito grit his back teeth in an effort to stop the smile that threatened to curve on his lips. Rule #3 No talking back. He said, "You didn't let me finish. Only Zero has to do them."

"What?" he exclaimed. Zero had stayed silent because he didn't care, but now Kaito was being unfair.

"Sleeping during my class is a worse offense than looking away from me," he said, seriously. "Go ahead. Her part isn't over. She has to sit on your back."

Stunned, Yori simply blinked. Takamiya waved his hand for her to do as he said. Gulping, she moved toward Zero slowly, afraid of how to proceed. Zero slowed his pace, not aware of it himself. Completely embarrassed, her face blushed pink, she set her feet on either side of his torso and squatted with her hands settling over the small of his back.

He stilled, momentarily overcome by the need to laugh out loud. Yori's body hovered above his back hardly touching him. Her warmth on his spine created an odd sensation in his gut that persisted. It felt good. He resumed moving, risking a glimpse in Kaito's direction. He was tight lipped and appeared somewhat bothered. That slight tilt of his head also gave him a quick view of Yori's exposed thigh, her skirt sliding dangerously up in her quasi sitting position. His mind, the part that reminded Zero he was a man, formed a possible image of what she looked like sitting on his back like that; him going up and down with her on top of him. Pretend it's another man, he repeated to himself.

This turned into a bad idea, Kaito thought. Yori wasn't even sitting properly on Zero. In his mind, she sat higher up between Zero's shoulder blades with her legs drawn up or cross-legged, unlike the horrible reality in front of him. It was semi comical, semi sensual. He had to look elsewhere.

Meeting the required 50 Zero force pushed himself up to his knees. Automatically, Yori stood up. Voice rough, he said, "What's next?"

Kaito didn't miss the attentions that Yori placed on Zero in school. They were subtle, so easy to miss. Zero never noticed, but right now he seemed slightly aware of his classmate. Yori also had a similar reaction. Finally, she was squirming. It secretly pleased him to elicit different facial expressions from the two of them. He said, surprising himself, "50 sit-ups."

Yori sat down first, despite her shock. She laid her jacket across her lap, tying it loosely in place. Zero took off his own giving it to her. Grateful, she set that on her lower legs. Sitting down in front of her, Zero put one foot between her feet the other opposite her left foot. Resting with her arms crossed in front of her, Kaito had an unbidden thought, looks like she's trying to hide her assets from perverts. In contrast, Zero had his hands behind his head, his white shirt showing off his arms and abs in his stretched pose. He is just asking for it, Kaito thought.

This time Zero want at Yori's pace. She did the first 20 steadily then beginning to feel the work out on her tummy she struggled. After sit-ups came squats. Back to back, he had them start on the 80 squats. By the end of it Yori's legs felt like quaky. Instinctively she grabbed Zero's arm, leaning her weight against him. It was ironic, but this was what she had wanted to avoid earlier. She didn't want to burden Zero. Now she didn't worry because he could push her away if he didn't like the slight heaviness. They stared at Kaito warily, awaiting his next order. Done messing with them, he said, leaving, "I'll see you here tomorrow."

How was it? If people really like it, I might write another chapter.
