A/N: Praise Be! I've been trying to upload this document since last night, and I was finally able to do it! Enjoy :) Also, children beware.

Chu Ga Eul did not do things like this.

Yi Jeong's shirt had long since been discarded, along with her bra, on the floor somewhere, and now she felt his mouth on her and his teeth as they pulled her panties down…down…down…

Chu Ga Eul did not do things like this.

He had asked her if she wanted a massage—they had been working so hard all day—and she had to admit it would be nice. Her shoulders had been bothering her.

Oh god, she never did things like this.

He told she'd have to take that off then—his shirt, he meant—and wouldn't she like to take her bra off too? It looked awfully tight. He flipped her over and told her to rest her chest and her head on some pillows while he stroked her back.

W-what was he doing? She never…she never…

It started out innocently enough, she supposed. He kneaded her shoulders and her upper back like he said he would and kissed her neck and told her how pretty she was.

Oh god, this had to be sin.

Then he trailed his hands down her back, down her hips, down her legs, tracing the outline of her body like she was a well-designed vase, and followed these gentle touches with light kisses on every part of her that wasn't pressed against the sheets.

Mmmm…Sunbae…

At one point, she'd gotten so used to his caresses that, lulled by the gentle rain beating against the window, she started to fall asleep, but suddenly she felt his lips against her ear, and he whispered for her to turn over.

More…She wanted more. She needed…harder…harder…oh…

Soon, she felt his mouth all over her chest and her stomach, his kisses growing sloppier and hungrier as he went further down, lingering on her breasts. Finally, he slid his hands up her thighs and fingered her panties, barely brushing the skin underneath, and the strange longing that had been welling up within her became a slow burn.

Ah…ah…ah…ah…more…

His mouth had always felt warm and tender, but now it felt firm and desperate, and her own body swelled to match his intensity. She clutched his hair in her fists. He built her up slowly, slowly, slowly…until all at once she came crashing down inside him, shuddering with the effort. When she finished, he kissed her hard on the mouth, and in half-awareness she kissed him back, the foreign taste lingering there only fueling her desire to draw him closer.

Chu. Ga. Eul. Did. Not. Do. Things. Like. This.

It was 3:00 A.M., and a steady, comforting drizzle had begun beating against Ga Eul's apartment window. Yi Jeong had settled down with his head on her chest-oddly, one of his favorite positions to sleep in-nuzzling her breast while she played with his hair. Or what was left of it since he had cut it short.

They hadn't said much of anything after their earlier encounter—Ga Eul was still trying to process it—but they hadn't gone to sleep either. Sometimes she thought Yi Jeong was falling asleep, but then he would shift his head and kiss her and ask if she was okay for the tenth time.

"I'm okay, Sunbae." She could feel her face flush even though he wasn't looking at her. "I…I liked it," she answered him.

"Good." He kissed her again. "I'm glad."

"But Sunbae," she whispered. "You tricked me."

"I did not trick you," he mumbled. "You know, people pay good money for those types of massages."

Actually, she did not know anything about it, but she had no doubt he did. Honestly, she felt like such a child compared to him sometimes.

Wanting to change the subject, she continued, "Is this part of the massage too? The part where the masseuse smothers the client?"

"If you're uncomfortable—" Yi Jeong started to sit up.

"Ani, I'm kidding." She grabbed his shoulder. "Lay back down."

His eyes met hers for a moment, and in a much quieter voice, she admitted, "I like holding you."

Not to mention she felt less self-conscious this way since she knew with his head laid down that way, he couldn't see her expression. Nor could he gaze curiously down at her entire body like he had earlier. She'd forgotten her embarrassment while he'd been kissing her, but now that her brain had begun functioning again, she felt rather exposed in the dim glare of her bedside lamp.

She pulled up the covers a bit more beyond her waist, and Yi Jeong wrapped himself around her more tightly as she pressed his face harder against her chest.

"Mm, you're sexy when you try to boss me around."

"Don't worry. I'll be sure to boss you around all the time in the future," she retorted.

"Good. I'll probably need your help with my next exhibition."

"Oh? Why?"

"Well, I was thinking about doing a theme on the human body. You can be my case study, Seongsaengnim." He trailed his fingers down the underside of her forearm. "I always wanted to seduce a teacher."

Ga Eul grabbed his hand and laced their fingers together to stop his assault.

"What? Why...Why are you telling me that?"

"It was one of my biggest fantasies in high school. But you know, none of my teachers were ever as good-looking as you. And they were mostly male. And old. Don't you think it's nice that I finally got my wish?"

"I think you should be reprimanded for bad behavior."

"Ga Eul-yang, I'm a bad guy, remember? I'm supposed to do bad things." Freeing his hand, Yi Jeong traced his fingers lazily over her right breast and kissed her again, harder this time.

"Besides, this is way better than my fantasies."

Ga Eul stayed quiet for a moment, some foreign yet overpowering emotion welling up within her. When she spoke again, she could barely hear herself.

"I like doing bad things with you, Sunbae."

She brushed her fingers up against his lips, and he took them in his mouth one at a time.

She cleared her throat.

"You're only allowed to do bad things with me, though."

She allowed him one final suck on her pinky finger, then pulled it out and caressed his cheek.

"Yes, Seongsaengnim," he answered, his voice sounding light and heavy at the same time.

Ga Eul remembered something and smiled. Cupping his face in her hand, she squeezed it.

"Jeongie."

"What?...Jeongie?"

She giggled.

"I'm your teacher. It'd be weird if I called you 'Sunbae.'"

"Maybe but…nobody's called me that since I was in kindergarten."

"I know. Woo Bin told me. I'm a kindergarten teacher, remember?"

"I'm going to kill Woo Bin when I see him again."

Ga Eul giggled more and mussed up his hair.

"Jeongie. I missed you Jeongie."

"You really are going to miss me if you don't cut it out."

"But Jeongie." She leaned down as far as she could. "You can be my bad boy, Jeongie," she whispered.

"Oh god, Ga Eul-yang." Yi Jeong squirmed a bit. "I swear, you're killing me."

Ga Eul laughed.

Relaxing again, he continued, "Okay, fine…Call me whatever you want."

"Thank you."

"As long as you're dressed like this, you can call me whatever you want."

"So Yi Jeong...You deserve a timeout."

"I knew you only wanted me for my body."

"What?"

"But if you insist, I'll stand in that corner over there, and you can admire me from the comfort of your bed."

"Y-yah…"

"I might even put on a show. Would you like to record this so you can watch it later?"

"Sunbae!"

"That doesn't sound like a 'no.'"

"Pabo. Don't you think we ought to get some sleep?"

"Ah, so this is the point in the evening where we graduate to 'Pabo.' You know I'm practically an insomniac. And you're stuck in this bed with me, which means you're not going to sleep either."

"I'm going to move to the couch."

"No, you're not. Your student is going to cry if you do that. Bad Seongsaengnim."

"Oh, really now..."

"You started it. Country girl."

"Casanova."

"But Ga Eul-yang...you know you like it."
