Anatomy lesson

Kyo stands behind his desk, with Seunghyun's assignment laid out before him. His fingers tap against the wooden surface and he looks at his watch—seems he's not going to be early this time.

Seunghyun opens the door and stumbles into the classroom a few minutes later than he was supposed to be. "I'm so sorry, Mr. Matsuura, I lost track of the time," he apologizes.

He's surprised at him. He's always on time, if not early. But he likes that he's not completely on point today. "People usually only lose track of time when they're doing something enjoyable," he says, throws a clever smile his way.

He smiles, biting his lip. He and a fairly close friend and crush Jin were sharing a cigarette in the parking lot and he hopes the smell hasn’t clung to him too much. Not that it's any of his business what he does after school. "Yeah," he says, and goes to sit at his desk.

The way he looks at him makes him think that he's being secretive, but he's not going to question him—he doesn't want a repeat of the previous porn conversation. "So," he says, picking up the assignment, "this is what I have for you today. If—when you finish it, I have something else we can go over. Extra-extra credit."

He nods and takes out his pencil and notebook so he can get to work.

After a while passes, he gets up to turn in his completed assignment and stands before him, prim and proper with his hands clasped behind his back.

Kyo smiles at him and sets his finished assignment aside. He grabs a number of papers from his desk drawer and stands from his chair. “You can sit for this,” he says and gestures back toward the desk he was occupying. When he sits back down, he goes to the front of his desk and leans against it. “Before we start this part I have to ask you a question,” he says.

"What is it?" Seunghyun asks.

"I know you said your parents didn't sign the permission slip for you to take sex ed., but they did give you permission to take extra credit with me," he hopes he's following what he's saying, "so I was thinking, we have extra time each week after your assignment, and if you want to know as much as your little friends know about sex...I could help you out with that. Unless you want to fall behind in that regard."

"I..." He is falling behind. He knows that full well. While the other girls and boys are moving on to blowjobs in their lover's cars, he's still never even seen a vagina or penis aside from his. His teacher wants to help him fit in. Without his help, he won't. "Yes," he says. "I'd appreciate that. You won't tell uanyone, will you?"

He's a little surprised at how he agreed so easily. He thought he might have had to coerce him into it. "I wouldn't tell a soul," he says with a smile, and adds, "as long as you don't either.”

"Oh, no, I promise. I won't tell anybody either." he says. He knows he can trust him because he has turned down his classmates, so he would never take advantage of him and his inexperience. He tells him so.

"Good," he says, "because you know, lying to me would be a sin, and I wouldn't want to turn you into a sinner." He grins, knowing full well he intends to make him the most beautiful sinner he has ever seen, but of course he can't know that.

"I wouldn't lie to you," he says. "What's on those papers?" He's relieved he wants to help him, that he has an actual adult on his side.

"Well, I know we don't have a lot of time left to this session, but I thought perhaps we could start off with the basics," he says, and then slowly places a sheet of paper on the desk before him, it has a basic drawing of a penis, with little arrows to each part, but the parts aren't labeled. "I assume you know what this part is called?" He grins pointing at a random obvious part of the penis diagram.

"Um... is this the urethra?" he guesses, but he has no clue. It looked like a monster from a horror movie to him.

He blinks at him in surprise, almost wanting to laugh. He could not believe that he doesn't even know what a penis really looks like. He has one right between his legs for god’s sake. "Um...no," he says, narrowing his eyes at him, "it's a penis glan, also known as the head."

"O-oh, of course..." he stutters. He curiously looks over the diagram, imagining that he has all these parts on the diagram between his legs. He had no idea it was so intricate. "Weird..."

"I suppose it can look a bit weird to some who’s not seen it so detailed yet," he says and then slides another sheet of paper toward him, a much simpler diagram of a penis, and there are fewer parts to label. "Maybe this will be an easier guess, since you already know the name of the first part."

"This part here is a shaft, isn't it?" It's hard to believe half the world, including his own self to have something so stupid looking dangling off of their middles.

"Ah yes, you get an A for effort, but," he looks at his watch, "our session is over. I want you to take these home with you, and when you come back next week, I want them properly labeled." He hands him one more sheet, a jumbled list of words for each part, and a few extras just to throw him off. "Here are the names of each part, and, Seunghyun, don't even think about cheating, cause I'll know." He gives him a smile.

"How am I supposed to know how to label these?" he asks, flabbergasted. He takes the papers and hides them away. It doesn't occur to him to turn down the assignment, because he would certainly be in trouble if caught with the pictures.

He watches with a smile as he hides the papers, he's obviously flustered again, he can see it in his body language. "You're a smart boy right? You're gonna have to give it your best try," he says, in an almost mocking tone.

With his face reddening fast, he gets up and heads for the door. He's setting him up for failure. This assignment is a trap to make him feel stupid.

The ride home that evening offered by Jin wasn't all that exciting. He mostly ignored him while he talked about swim. And that night, he puzzled over his new diagrams and logically tried to label everything. Part of him wanted to look between his own legs but he didn't quite have the courage to do so.

---

At their next session, after school, he lays the papers in front of him. He really did the best he could with his little knowledge of the subject.

Kyo takes the papers from him and simultaneously passes him, his next assignment to be completed. He's amused as he looks over his efforts with the diagrams. He's barely got any of the parts written correctly and he almost laughs at where he chose to put the clitoris—he's got it marked on the penis. He only has a few marked properly, but he thinks those might have been lucky guesses.

He takes the assignment and goes to his desk, humiliated by the mirth on his face. He must think he's so funny and clever. Why, all those terms probably weren't even real. He probably made them all up. He buried his head behind the papers in front of him. 

He continues to look over what he's labeled, and when he's finished he sits back in his seat and watches him, with interest as he works on his other assignment—something he's actually knowledgeable about.

Opening his drawer, he pulls out a hand mirror—one he took from home for this exact occasion—and places it on his desk with a grin of amusement.

Seunghyun looks up when the drawer opens, and he watches him put a mirror in front of him. "What are you doing?" he asks him, putting down her pencil, slightly alarmed. 

"It's for your next lesson," he says with a grin that reaches to his mischievous eyes. He looks at his watch. "Which is just about upon us."

Seunghyun hasn't the slightest idea what they could be using a mirror for, but after last time, he doesn't have high hopes that this will be an easy lesson. He quickly finishes up and turns in his work.

He takes his completed assignment—barely interested in whether he's got any of it right or not—and with the mirror in hand he stands from his chair and begins to walk around his desk towards him. "Now, tell me... Do you really think the clitoris is on the penis?" He questions him with a taunting smirk.

"Yes... Is it not? Well, how was I supposed to know?" he defends himself, backing up a step so his backside touches his desk. That look on his face... he's never seen anything like it. It excites him as much as it scares him. He has a sudden, strange thought that he's going to try to kiss him. He might even let him.

"I can't say, I just thought maybe you had some useful information inside that cute head of yours," he says, stepping closer, and he has nowhere to go now that he's backed up against his desk. "Perhaps, maybe you learn better with a... hands on approach, what do you think?"

He would try to push him away if he weren't so frightened and shocked. He forces himself to look him in the eye. "Hands on in what way?" Slowly, he's putting the pieces together. A hand mirror, lessons about the parts between his legs... oh.

“I think you're smart enough to figure that out,” he says, now standing directly in front of him. “How do you suppose we proceed?” He grins.

"I... I thought you didn't fraternize with your students," he stammers, his cheeks reddening quickly. But inside, he's thrilled. Him. He chose him. Aloof with all the rest, he only gave him this attention. No one else.

"But I'm afraid you're correct. I don't fraternize with students," he says, twirling the mirror in his hand, "But, you are in need of a proper education, and if I were to deny you that I wouldn't be a very good teacher now, would I?"

"No...I guess not," he says slowly. "But...are you going to look at it, too?"

"If I don't look, how will I be able to educate you?" He asks, seriously, but there is a smirk on his lips. He steps closer then, barely a couple inches between them. "I think you need to take off your briefs for this part," he speaks in a hushed, seductive, and low voice.

This close Seunghyun could smell the mint on his breath and his slightly spicy aftershave and faint hint of tobacco; cigarettes perhaps. His heart thuds painfully—and something else on his lower body throbs to life. He pressed his thighs together and looks into his eyes, his moist lips parted like he's stunned. Slowly unbuckling his belt and slipping a hand under his dark skinny jeans, he hooks his fingers into the sides of his boxer briefs and slides them down his legs, straightening again when they're around his ankles alongside his belt and pants.

Kyo looks to where his briefs have dropped to his ankles and smirks. "Sit. On the desk," he says, now looking up at him, into his soft deer-like brown eyes that are trying to stare him down, like he's above him, but he can see the hesitation in his eyes, and in his mouth that quivers slightly.

"Yes, Mr. Matsuura," he says, shuffling onto the edge of the desk, his briefs and other garments falling to the floor completely. He can feel himself getting stiff below from the intensity in his gaze, from him being so very close to him. He presses his knees together, a weak show of resistance.

"Here, hold this," he says and presses the mirror into his hand. He moves around the desk, behind it, behind him, and puts his head almost next to his, nearly able to rest his chin on his shoulder. "I want to see what you see," he whispers near his ear, and reaches to the hem of his over-sized white dress shirt, to slowly pull it up his thigh, exposing his nude bottom half of the body completely.

"No, we... we really shouldn't," he murmurs, putting his hand over his to stop his progression.

"You want to stay a stupid little boy then?" He says to hos ear, knowing a small kick to his intelligence is just what he needs to keep him from resisting.

He shakes his head and relaxes his hand, bringing the mirror down between his thighs, parting them slightly. He barely breathes.

When he parts his legs enough that he can hold the mirror between his thighs, Kyo grins—even though he can't see him. "Good boy," he nearly purrs, he could see a perfect view of his hardening member, naturally covered at the top in delicate soft black hair. "What do you see?"

He looks down at the mirror. "Um... it looks like a monster," he says. "A really ugly monster."

"I see something very attractive," he says, a compliment even, "your patch of hair down there is also very fitting." His hand touches his thigh, and along his soft fair skin. "I bet it smells as nice as it looks."

"Mr. Matsuura..." he says. "How would that be educational?" He's teasing a little. His hand leaves his and rests on the desk. "So if this at the tip is not a clitoris, what is it?" he asks.

“The glans,” he says and, with his mouth pressed near his ear, he lets his hand move over his thigh, to the beginning of his hair covered shaft. “The glans are a small bundle of nerves, and it's only purpose is to bring you pleasure,” he says and his index finger moves upwards, locating the aforementioned bundle of nerves and he moves his thumb over it.

He jerks backwards, the desk moving slightly with the jolt from his body, and his hold tightens on the mirror, his breath coming in helpless pants. He touched him... where no one has ever touched him before.

Kyo slowly, agonizingly teases his tip. Rubs in short strokes, and tiny circles. "Have you ever touched yourself here before?" He wonders.

His whole body is tense, taut, pulled tight, on the exquisite edge of pleasure and discomfort. He shouldn't be doing this. He shouldn't be letting him do this. Everything in his mind tells him this is wrong. But the foreign feeling of someone touching him felt so good. He shakes his head, biting his lip to prevent himself from making any vocal sounds.

"It feels good doesn't it," he says with a wicked grin, "but this isn't allowing you a full education." He stops touching his tip, and with three fingers he gently stroked his hardening shaft, careful not to grip hard. "This right here, is called your shaft... Do you remember that from the sheet?" He asks.

He nods, shuddering. He's sure he can tell how wet he is, but hopefully he won't mention it. It's terribly inappropriate of him to be aroused by his English teacher touching him like this. His hand which holds the mirror trembles.

He stops stroking his shaft and places his hand on his balls. "And these lovely round things, are your testicles," he says as he begins to massage them carefully, watching his movements in the mirror, "these are really fun to lick and suck."

His head rolls back, back arching, and he can't help but moan softly in the moments where he forgets himself, where he is and whom he's with. Then it comes back to him in a rush and he tries to quell the deep red blush spreading from his cheeks. But he doesn't jerk the mirror away, can't bring himself to, though when he looks down he sees the reflection is foggy so he can barely make out what he's showing him.

"You really need to show a bit more restraint Seunghyun, I don't feel like you're paying attention to my lesson," he gently scolds him.

"I'm sorry, I can't help it," he whimpers. He's only half convinced that he wants to teach him; most likely he wants this, too—and while he worries over this, his fingers are becoming wet with him.

Still massaging at his balls, he uses another finger to touch over his entrance. "Just below and near your testicles, is your anus, and right at this spot…" He moves his finger right over his entrance. He whispered lowly to his ear, "Do you know what can happen here?"

"Maybe..." He squirms, panting. His free hand grips the edge of the desk in an effort to steady himself, but he's trembling all over.

"Seems you're not a complete idiot," he says, and rubs his finger over his swelling opening a moment before pulling his hand away completely. "Our lesson is over for the day," he says, speaking into his ear, "I hope the wetness from your cock hasn't left a stain on my desk."

Lurching forward, away from his hot breath, he gasps, slamming the mirror onto his desk and taking a firm step away. Tears of humiliation and shame and—worst of all—excitement, pricked at his eyes. He doesn't move, trying to compose himself. 

He looks at him from beneath his thick brows, and his mouth twists into a grin. He looks scared, nervous, and tense. He looks down to the mirror on his desk, then to the damp spot next to it, and when he looks back up at him, he smiles. "Don't forget your briefs."

He shakily retrieves his briefs and the rest of his bottom garments, slipping them back on hurriedly, carrying his backpack, before nearly running out of the door, through the empty hallways, the click of his dress shoes echoing and covering the sound of his pounding heart.
