TTDOTO 5.1

The tutoring game, half-decided by threat, began as soon as Jae-an’s cold subsided.

[—–. —–.]

Lying dazed, watching TV, Jae-an jolted at the phone’s ring, rising from the sofa.

Drawn to the relentless ringing, he stood before it but hesitated, hand frozen. What if it wasn’t Jae-rim? Still, he couldn’t let it ring out. After deliberating, he grabbed the receiver, his curled fingers gripping it tightly.

[“Why just stare at the ringing phone?”]

“…Thought it might not be you.”

Though his throat’s swelling had eased, his voice was markedly different—slurred, quieter, as if he’d forgotten how to speak clearly. Like a cowed man, Jae-an mumbled, trailing off.

[“Who else would call you, hyung?”]

You’ve got plenty of dangerous friends you don’t tell me about. He wanted to snap back, but swallowed it. Jae-rim ordered him to wait by the gate for 20 minutes and hung up.

Picking clothes for the season, his hand wavered. It’d been so long since he’d gone out, he didn’t know the weather. He chose a short-sleeve tee, a casual black jacket, and dark jeans.

Though Jae-rim had picked them by eye, the clothes were slightly big. After roughly tousling his freshly washed hair, he slipped on sneakers and waited by the gate.

Trapped indoors, he hadn’t noticed how nice the weather was. Cool spring breezes and rustling green leaves caught his gaze. Sunlight, softened through the foliage, warmed his skin.

Thinking of teaching the inscrutable Jae-rim stirred dread and unease, but the fresh air quickened his pulse. It was a rare sense of freedom. Maybe, as Jae-rim said, he craved this outing.

An engine hummed faintly, and Jae-rim’s car appeared. Spotting him, it slowed, stopping before him. Climbing into the passenger seat slowly, he felt Jae-rim’s yellow eyes scan him from head to toe.

“Suits you well.”

“…Does it?”

Embarrassed by the direct compliment, he averted his eyes, buckling up. Jae-rim smiled, eyes curving like crescents.

“Yeah. You look pretty in anything, though.”

His casual, syrupy words stirred an indescribable feeling. Unable to reply, Jae-an turned to the window.

The car sped smoothly along the road. In under ten minutes, they reached the restaurant. As Jae-rim opened the door, all eyes—staff’s—turned to them.

“Hello, boss.”

“Long time no see!”

Staff greeted them variably. Jae-an forced a bright smile, as he used to, but it felt heavy, like weights hung on his lips, awkward.

“Here to eat?”

“No, not that…”

“Don’t mind us, get to work.”

Fumbling for a response, Jae-an was cut off by Jae-rim’s smooth reply as he strode past. The staff smiled. Jae-an, catching their cheerful expressions, bit his lip.

Did it look odd, visiting the restaurant with Jae-rim on a weekday afternoon? No bruises on his face, right? Was his smile awkward? Every action gnawed at him. Instinctively heading for the private room, Jae-rim grabbed his hand.

“We’re going upstairs.”

“Oh… okay.”

Trying to free his hand before the staff noticed, Jae-rim pulled harder, his grip stinging.

They climbed the staff stairs to the second floor. Through a door, a hallway with a few artworks led to a spacious room. Jae-rim punched in a code to enter.

This seemed to be his office. A bookshelf lined with culinary books stood against the wall, a black sofa and table for meetings in the center.

Jae-rim pulled Jae-an to the sofa, then strode to the bookshelf. Jae-an, recalling the bustling restaurant despite past lunchtime, asked,

“Don’t you need to cook?”

“Nope.”

“Don’t customers come for your food? …Is that okay?”

“Luckily, it’s not going under.”

Jae-rim’s reply carried a mocking edge, likely catching Jae-an’s desperate attempt to see him as a chef.

He grabbed a workbook and a pencil case, sitting beside Jae-an. The sofa tilted under his weight, and Jae-an steadied himself.

“Bought the same workbook as before, but the content’s a bit different.”

“Yeah, the curriculum changed…”

Flipping through calmly, Jae-an asked,

“Some problems need concepts explained again… Should I?”

“Do what you want. I just need your voice.”

Jae-an’s fingers trembled slightly. Showing dislike would only provoke Jae-rim to force his emotions. Feigning calm, he grabbed a blue-ink pen from the pencil case.

“Let’s start.”

Pushing the workbook toward Jae-rim, he began explaining. He read concept pages, showed how to solve problems, had Jae-rim try similar ones, identified his strengths and weaknesses, re-explained tough parts, and repeated.

At first, it felt absurd, but Jae-rim’s serious attitude lent a tutoring-like atmosphere.

Listening to the pencil’s soft scratches, Jae-an’s mind eased unknowingly. It was odd seeing Jae-rim, whose math skills had rusted, solve problems with his guidance.

When Jae-rim finished, he asked for the grading. Circles piled up—a parade of correct answers—melting Jae-an’s guard.

“This part’s easy to mess up, but you did well. If you solve it another way—”

Excited, about to share an easier method, Jae-rim cut in.

“Your last job was at a boys’ high school, right?”

“Yeah. Why?”

His pen slipped at Jae-rim’s casual follow-up.

“Bet all the boys got hard in your class.”

Jae-an’s eyes turned icy. This was Jae-rim—adept at toying with hearts, shredding the best moments into despair.

Unable to continue, he shut his mouth. He couldn’t look at Jae-rim or keep explaining calmly. Clutching the pencil, face shadowed, Jae-rim drawled lazily.

“Why so serious? Just saying.”

Infuriatingly nonchalant, he tapped the workbook, lips curling prettily.

“Lighten up and finish explaining.”

Closing his eyes briefly, Jae-an licked dry lips and resumed. But Jae-rim’s crude remark had set his nerves on edge. He finished explaining halfheartedly, assigning another problem.

Watching Jae-rim solve it, he bit at a hangnail.

Trying to calm himself, every move of Jae-rim’s pencil hand made him flinch. That hand might toss the pencil and grope his stomach or chest.

But, unlike his fears, Jae-rim just solved problems, setting the pencil down.

“Done.”

“Huh? Oh, yeah.”

Surprised nothing happened, Jae-an, hands sweaty, grabbed a red pencil to grade.

“All correct.”

“Nailed it, right?”

Seeing Jae-rim smile at the circled page, he looked like a high schooler. Memories tugged at Jae-an, dazing him. Nodding a beat late, Jae-rim tilted his head, locking eyes.

“Give me a kiss as a reward.”

Tapping his cheek with a finger, his long-lashed, pretty eyes curved coolly.

“What? I held back well.”

As expected. Jae-an, face bloodless, stared, then leaned toward his cheek, resigned. But Jae-rim turned, capturing his lips.

“…!”

Shocked, his body stiffened, but he clenched his fists, not pulling away. Complying with Jae-rim’s wants was the fastest way to end this madness.

Yet, despite calling it a kiss, Jae-rim’s tongue slithered in, licking inside. Wet sounds echoed in the quiet office. Jae-an endured, blood chilling. He yielded his lips and tongue until Jae-rim slowly pulled back, letting him wipe saliva with the back of his hand.

“Haa…”

As if nothing had happened, Jae-an closed the workbook, put away the pencil and pen, and sighed softly. Today’s tutoring portion was done.

“Okay, let’s stop here.”

“Yep. Good work.”

Surprisingly, it ended without much incident. A lewd comment and a kiss were nothing compared to Jae-rim’s past vile acts.

Right after, Jae-rim drove him home. The door closed as he stepped inside, the lock’s click signaling the end of his brief outing. It felt like a fleeting trip to another world.

With a sunken face, Jae-an slipped on slippers, scanning the silent house. CCTV lenses everywhere began choking him.

Unable to stay inside, he fidgeted with his neck and sat on the terrace. The garden was beautiful, but the glass walls blocked the cool air and warm sunlight.

“…So stifling.”

A faint sigh slipped through dry lips. Going out meant enduring Jae-rim’s harassment. Weighing shame against freedom, he measured which tipped the scale.

If it were just like today, he could bear it… A pathetic thought, but his longing for freedom tilted his heart.

Reaching for the glass, he touched the unreachable outside. The clean pane was smudged with fingerprints.

*****

But Jae-rim always shattered expectations. On the first tutoring day, he’d acted tame to lower Jae-an’s guard. From the second session, he openly indulged his desires.

From the start, he kneaded Jae-an’s inner thigh, then trapped him between his legs by mid-session. Holding him from behind, Jae-rim buried his lips in the soft skin of Jae-an’s nape throughout the explanation.

Thirsty for outings after days, Jae-an endured the revolting touch, unable to stop it as it escalated, loath to waste his endurance.

“So, you match the coefficient first, ah…”

But when a cold hand slid under his clothes, Jae-an dropped the blue pen. Touching over clothes was one thing; bare skin was another.

“Hey…”

Unable to hide discomfort, he twisted, but Jae-rim’s hold prevented escape. The intrusive hand toyed with his nipple. Half-turning, Jae-an stammered,

“Are you… listening?”

“Of course.”

“Stop… touching.”

“You don’t like it?”

Nodding, Jae-an heard a low, puzzled hum from behind.

“Your nipples are so hard, though.”

“That’s… because you keep touching.”

“You’ve tried it?”

“No…”

“Then how do you know?”

The fingers grew forceful, pinching and twisting painfully. Swallowing a groan, Jae-an grabbed Jae-rim’s wrist, pulling it down.

“Just… I know…”

“…Like a slut.”

“What?”

The crude term flipped his voice in shock. Jae-rim, now sullen, licked from his earlobe to behind his ear, sticky and warm.

Hot breath and saliva spread on his burning ear. Jae-an jerked his neck back, squirming.

“Stop, I said…”

“Just explain. I don’t get the next one.”

His lazy but oppressive tone forced Jae-an to stop resisting and write equations.

“So, calculate this first, thinking of the coefficient, ha…”

But focus was impossible. His shaky, anxious writing lost its neatness, wobbling crookedly.

As fingers circled his sensitive nipple, Jae-an forgot his explanation, trembling with eyes shut. Jae-rim dragged a 30-minute lesson into an hour.

Then, a hand fondling his side slipped into his pants. Jae-an’s eyes snapped open, surrendering first.

“Ugh, Jae-rim…!”

“What?”

“We agreed no touching outside… at the restaurant…”

“No one’s coming in, so just explain.”

“I can’t if you touch me.”

“Then don’t.”

Jae-rim unbuckled his pants, the oversized waistband slipping to reveal his bare lower body—no underwear. Jae-an twisted, making a different sound than with the nipple touching.

“Stop, please…!”

His protest grew loud unwittingly. Bloodshot eyes welled with hot tears. But Jae-rim, openly ignoring the math, stroked his bare skin.

With no underwear, the cold hand reached his lower abdomen and groin. The pencil lead snapped, and Jae-an’s hand slid across the workbook.

“Ugh… stop it…!”

Easily subduing his struggles, Jae-rim grabbed his limp penis and balls, chuckling silently.

“Acting like a big brother with this pathetic thing?”

Kneading the small bundle, Jae-rim gripped the tip, shaking it lightly. The flaccid penis stirred under skilled hands.

“Ah, ah…! Jae-rim, please stop…!”

“Look, it’s getting hard.”

Whispering with a laugh, Jae-rim’s hand pressed with perfect pressure and warmth. Jae-an hated hardening under his touch, but the relentless stimulation made his penis rise. Glaring at it with disgust, he choked up.

“Stop, I’m begging you…!”

Shaking his head, he twisted his hips. But Jae-rim’s strength overpowered him. Laughing mockingly, he pinned Jae-an’s pelvis, rough palms circling the tip. The reddened glans throbbed with unbearable sensation. Jae-an clenched his thighs, shuddering, barely stifling cries for fear of being heard outside, pleading desperately.

“No, no, Jae-rim… please…”

“Doesn’t seem like you hate it, standing so tall.”

Mocking his physical reaction, Jae-rim giggled in his ear, the sound pounding his brain.

Finally, Jae-an buried his tear-soaked, flushed face downward. His body, losing will, spasmed intermittently. Soon, an unbearable urge to release hit, his fist clenched tight, and fluid shot from the tip.
