During Science Class, Hervi and Ced got paired up for Sex Ed and their task is to extract Cum from Ced for the lab tomorrow. Hervi is disgusted with this but had no choice because it's for grades. Their teacher told them that Hervi could help Ced by stroking his dick with her hand or just let Ced stroke on his own while Hervi is standing there. Hervi couldn't understand why it has to be them. When tomorrow comes, Hervi thought that what if she'll let Ced see her Body while only wearing a bra and panties in the lab. In the lab, Ced began stroking to Hervi. Hervi is really disgusted. But slowly tried to calm her self down and got close to Ced and sat beside him. She hold Ced's Cock and curiously asked him how to properly stroke it. He taught her and let her go with it. Ced alerted Hervi that he's cumming and Hervi immediately put her mouth into him instead of aiming it into the small cum. She didn't swallow it but instead, let it stay in her mouth. Ced now in uniform while Hervi is still comfortable with her Panties and Bra, didn't wore her blouse and Skirt and head to their classroom. Their teacher asked where it is and Hervi told their that she accidentally swallowed it but it is still in her mouth in truth. Their teacher said it's ok and just told Hervi to try again next time.

Chapter 1: Bra and Panties, Sample in Hand

The specimen room smelled like a dentist's office and a hospital bathroom had a baby, then abandoned it in the basement of the science building. Hervi pressed her back against the cold metal door, her palms flat against the surface, as if she could will herself through it and back into the hallway where the air didn't taste like antiseptic and existential dread.

Fluorescent lights buzzed overhead. One of them flickered—a nervous, twitchy pulse that made the shadows in the corners dance.

"You're doing the thing again," Ced said from somewhere to her left.

She turned her head. He was sitting on the edge of the exam chair, that cracked vinyl monstrosity bolted to the floor like someone might try to steal it. His hands were folded in his lap, his posture relaxed, like they were waiting for a bus and not about to do something that would absolutely, positively ruin her GPA if anyone ever found out.

"What thing?" she asked, even though she knew exactly what thing.

"The thing where you look like you're about to bolt." He tilted his head, and a strand of dark hair fell across his forehead. "You've been doing it since Nakamura handed us the assignment."

Hervi pushed off the door and crossed her arms. The movement was too fast, too jerky. She felt like a marionette with tangled strings. "I'm not going to bolt. I'm just... acclimating."

"Acclimating."

"Yes. To the environment." She gestured vaguely at the room—the gray walls, the single chair, the small steel table where the collection cup sat like a judgmental little sentinel. "It's very... clinical."

Ced laughed. It was a low, easy sound that didn't belong in a room with this many disinfectant fumes. "It's a sex ed lab, Hervi. I don't think they were going for ambiance."

She felt her face heat. That was the problem, wasn't it? Her face was always doing that—betraying her, flushing at the worst possible moments. She'd spent her entire academic career cultivating an image of cool, detached competence. And now she was standing in a windowless room, about to do something that would make her blush so hard she'd probably combust.

Professor Nakamura's voice echoed in her head, calm and matter-of-fact: The purpose of this lab is to demystify human reproductive biology through direct observation and participation. You will work in pairs. You will collect a viable sample. You will not leave this room until the task is complete.

Easy for her to say. Nakamura probably hadn't blushed since 1997.

"Okay," Hervi said. The word came out too loud, too sharp. She cleared her throat. "Okay."

Ced raised an eyebrow. He didn't say anything, which she appreciated. He just waited, patient as always, those warm hazel eyes tracking her like she was a skittish animal he didn't want to spook.

That patience was going to kill her.

She'd been paired with Ced by alphabetical accident—Herrera and Kimura, seat numbers fourteen and fifteen. She'd known him vaguely before the semester started. Saw him around campus, in the library, at that one party freshman year where he'd spent twenty minutes explaining the rules of cricket to a group of people who definitely didn't care. He was the kind of guy who seemed comfortable everywhere, like he'd figured out some secret to existing that everyone else missed.

She'd never talked to him before Nakamura's class. Now she was about to see him naked.

Life was a cruel, cruel joke.

"We should establish parameters," she said, pacing a short line between the door and the table. Three steps one way, three steps back. "Ground rules. Boundaries. Things we're both comfortable with."

"I'm comfortable with whatever you're comfortable with."

"That's not helpful."

"It's honest."

She stopped pacing. Looked at him. He was still sitting there, still relaxed, still not looking at her like she was a science experiment gone wrong. She thought about the statistics—about the surveys she'd read, the research she'd done in a desperate attempt to feel prepared for this moment. Most college students would have hooked up by now, would have had some experience to draw from. But Hervi wasn't most college students. She'd been too busy, too focused, too scared of losing control of the carefully constructed life she'd built.

She'd never seen a penis in person. Not a real one. Not up close.

And now she was supposed to collect a sample of sperm like she was harvesting cells in a petri dish.

"Fine," she said, and her voice only cracked a little. "Fine. I can do this."

Ced stood up. He moved slowly, deliberately, giving her time to adjust to the idea of him standing. He was tall—she'd always known that, in an abstract way—but now, in this small room, he seemed to take up too much space. His shoulders were broad. His hands, resting at his sides, looked capable of things she didn't want to think about.

"You don't have to do anything you don't want to," he said.

"I know."

"I mean it."

"I know." She swallowed. Her throat felt like sandpaper. "But I'm not going to fail this assignment."

He studied her for a moment. The fluorescent light flickered again, and his expression shifted—something she couldn't read. Then he nodded, slow and resigned.

"Okay," he said. "What do you want me to do?"

Here it was. The threshold. Once she crossed it, there was no going back.

Hervi took a breath. Then another. She thought about her transcript, about the 4.0 she'd maintained for three years, about the scholarship that depended on her grades. She thought about Nakamura's face, expressionless behind those rectangular glasses, saying, Try again next time, as if failure were nothing, as if embarrassment were a choice.

She thought about all the things she'd never let herself want.

"Take off your pants," she said.

Her voice didn't shake. She was proud of that.

Ced didn't smirk. Didn't make a joke. He just undid his belt with steady hands, then unbuttoned his jeans and pushed them down. His boxers went with them. He stepped out of the pile of denim, kicked it aside, and stood there in a t-shirt and socks, his cock semi-hard against his thigh.

Hervi's mouth went dry.

She'd underestimated how much flesh there would be. How much skin. The pale curve of his thighs, dusted with dark hair. The weight of him, hanging there like it was nothing, like he showed this part of himself to people all the time.

He was looking at her. Patient. Waiting.

"Okay," she said again. The word had become her anchor, the only thing keeping her tethered to the floor. "Okay, I'm going to..."

She trailed off. Trailing off was not okay. She needed to finish her sentences.

"I'm going to take off some of my clothes," she said. "Because you're... and I'm... it's only fair."

"Fair doesn't have to matter here."

"It matters to me."

He nodded. Didn't argue.

Her fingers found the hem of her sweater. She pulled it over her head in one clean motion, folded it with mechanical precision, and set it on the table next to the collection cup. Her jeans followed. She stood in her bra and panties, her arms crossed over her chest, her skin pebbled with goosebumps from the cold.

Ced looked at her like she was something worth looking at.

She hated how much she liked that.

"Now what?" he asked.

It was a simple question. It shouldn't have made her pulse spike.

"You..." She uncrossed her arms. Dropped them to her sides. Tried to look like someone who did this all the time, someone who was casual about bodies and sex and all the messy things that happened between people. "You do your thing. I'll... help. If you want."

"Do you want to help?"

"I'm asking if you want me to."

His smile was small. Tilted. The kind of smile that made her want to punch him and kiss him at the same time.

"Yeah," he said. "I want you to."

He sat back down on the exam chair. It creaked under his weight. Hervi turned to face him, and her legs felt like they belonged to someone else, someone braver, someone who didn't spend her weekends memorizing amino acid structures instead of learning what it felt like to touch another person.

She pressed her palms against the cracked vinyl seat on either side of his hips. His thighs were warm against her elbows. She thought, briefly, about falling off the edge of the earth and ceasing to exist.

He reached down. Took himself in hand. The motion was practical, almost businesslike—something he'd clearly done a thousand times before.

"Come here," he said.

She came here.

She knelt beside the chair, her knees pressing into the linoleum. From this angle, she could see everything—the length of him, the curve, the way his thumb swiped over the tip in a slow, deliberate rhythm. Her chest tightened. Her breath came shallow.

"I'll guide you," he said. "Just follow my hand."

His fingers closed around hers. His palm was rough. His grip was warm. He positioned her hand—one around the base, one cupping the head—and then he let go, leaning back, his eyes half-closed, his breathing steady.

She fumbled at first. Too hard, then too soft. The slickness of him surprised her—skin like velvet, pulse like a heartbeat. He whispered instructions, his voice dropping into something deeper: slower, lighter, twist your wrist a little at the top. She followed. She followed like it was a lab protocol, like it was a formula she had to balance, and somewhere in the middle of it her body stopped shaking. Her mind stopped screaming.

She replaced her hand with her mouth.

The taste was salt and skin. The heat of his body pressed against her tongue. He made a sound—a ragged exhale, torn from somewhere deep—and his hips bucked reflexively against her, once, before he forced himself still. His fingers tangled in her hair. His breathing stuttered.

"Cup," he said. "Hervi—cup, I'm—"

She didn't stop.

Later, she'd wonder what had possessed her. Later, she'd rationalize it—efficiency, maybe, or curiosity, or the strange, sharp pleasure of having made him lose the composure he wore so easily. But in that moment, there was no thought, only the overwhelming need to see this through, to hold onto the fierce and reckless feeling of having power over someone else's body.

He broke apart against her tongue. She swallowed—instinct, not decision—and when she stood up, her legs barely holding her, her lips wet, her chest heaving, he was looking at her like she had just rewritten the laws of physics.

"Cup," he repeated, dazed.

She shook her head. Smiled.

The door clicked behind her. The hallway stretched ahead, long and empty, the sounds of Nakamura's lecture echoing from the open door at the end of the corridor. Hervi adjusted her shirt, smoothed her hair, and walked back into the classroom with her secret hidden behind her lips.

Nakamura looked up from her notes.

"Sample?" she asked.

Hervi opened her mouth. Showed her teeth. Said nothing.

For the first time all semester, she wasn't blushing.

The silence stretched between them like a held breath.

Professor Nakamura's pen hovered over her clipboard. Her eyes, sharp and dark behind those rectangular glasses, flicked from Hervi's face to the empty collection cup still sitting on the corner of her desk, then back again.

"Interesting approach," she said.

Hervi kept her expression neutral. Her tongue pressed flat against the roof of her mouth, holding everything in place. She could taste him still—salt and something almost sweet, a flavor that didn't belong in a classroom under fluorescent lights and the distant hum of a ventilation system.

"I'll need to log the sample properly," Nakamura continued, setting down her pen. "You can bring it to my office hours tomorrow. Before noon."

Hervi nodded. A small, controlled movement. She didn't trust herself to speak.

Nakamura's gaze lingered for a beat too long. Something flickered behind her glasses—not surprise, not disapproval, but something closer to amusement. Or maybe curiosity. Then she turned back to her notes, already moving on, already done with Hervi and whatever she had or hadn't just witnessed.

"You can take your seat."

Hervi walked to her desk in the back of the lecture hall. Her legs felt strange—detached, like they belonged to someone else. She was aware of every sensation in her body: the cool linoleum under her shoes, the brush of her jeans against her thighs, the slow drip of saliva pooling behind her teeth.She sat down. Folded her hands on the desk. Stared straight ahead at the whiteboard where Nakamura had drawn a diagram of the male reproductive system, complete with labels in neat, clinical handwriting.

Seminal vesicle. Vas deferens. Epididymis.

She'd memorized all of them last week. Now they felt like words in a foreign language.

The lecture continued. Nakamura moved through the material with practiced efficiency—hormonal regulation, sperm production, the biochemistry of arousal. Hervi took notes. Her handwriting was steady. Her breathing was even. To anyone watching, she was just another student, just another body in a seat, just another brain absorbing information.

No one knew.

The thought sent a strange thrill through her, sharp and electric. She pressed her thighs together under the desk and tried to focus on the difference between meiosis and mitosis.

Ced didn't come back to class.

She noticed his empty seat five rows up, the desk where his notebook still sat untouched, the pen he'd left behind. He was probably still in the specimen room, probably still sitting on that cracked vinyl chair, probably still staring at the ceiling and wondering what the hell had just happened.

She wondered too.

When the lecture ended, Hervi gathered her things slowly. The other students filed out in a blur of chatter and backpack straps and phone screens glowing in the hallway. She stayed until the room was almost empty, until Nakamura had packed her briefcase and nodded goodbye, until the only sound was the hum of the lights and the whisper of her own breathing.

Then she walked to the bathroom on the second floor, locked the door, and spat into the sink.

The sample slid down the drain with a swirl of water. She watched it disappear, her hands gripping the porcelain edge, her reflection staring back at her from the mirror—pale, wide-eyed, a stranger wearing her face.

She rinsed her mouth. Washed her hands. Counted to ten.

Then she went back out into the corridor and walked to the library like nothing had happened.

---

Ced found her three days later.

She was in her usual corner on the fourth floor, surrounded by textbooks and highlighters and the cold dregs of a coffee she'd bought six hours ago. The library was quiet—that specific, dusty silence that made every sound feel like a crime. She didn't hear him approach until he pulled out the chair across from her.

She looked up.

He was wearing a gray hoodie and jeans with a hole in one knee. His hair was messier than usual, like he'd been running his hands through it. He held two cups of coffee from the campus café, and he set one in front of her without asking if she wanted it.

"I figured you'd be here," he said.

Hervi closed her textbook. Her heart was doing something complicated in her chest—a quick, arrhythmic knock that she didn't appreciate.

"How'd you know?"

"Lucky guess." He sat down. Took a sip of his coffee. His hands were steady. His eyes were steady too, watching her with that same patient expression he'd worn in the specimen room. "You left before I got back."

"I had things to do."

"Things."

"Yes. Things." She wrapped her fingers around the coffee cup and didn't drink. The warmth seeped through the cardboard and into her palms. "You missed a pretty boring lecture. Hormonal feedback loops. Nothing you can't get from the slides."

"I wasn't worried about the lecture."

The way he said it—quiet, direct, no games—made her throat tight.

She looked at him. At his tousled hair, his warm eyes, the slight curve of his mouth that could have been a smile or could have been something else entirely. She thought about the sound he'd made when he came, the way his fingers had tightened in her hair, the way he'd said her name like it was a question and an answer at the same time.

"I don't know what you want me to say," she said.

"I don't want you to say anything."

"Then why are you here?"

He leaned back in his chair. The library lights cast shadows under his eyes, made him look older than he was. For a moment, he seemed like someone who'd been through things she couldn't imagine—things that had nothing to do with sex ed labs or awkward assignments or the strange intimacy of a locked room.

"Because I wanted to see if you were okay," he said. "And because I wanted to give you this."

He reached into his hoodie pocket and pulled out a small envelope. Plain white. Unmarked.

Hervi took it. Opened it. Inside was a single index card, folded in half.

Written in his neat, blocky handwriting: I had a 4.0 before this semester too. That assignment didn't change it. You're still the smartest person I know.

She stared at the card for a long time. Longer than she should have. Long enough that her vision blurred at the edges.

"That's a weird thing to write on a card," she said finally.

"I know."

"You could have just texted me."

"I don't have your number."

She laughed. It surprised her—a real, unguarded sound that echoed in the quiet library and made a few heads turn at the next table. She slapped a hand over her mouth, eyes wide, and Ced's smile widened into something genuine.

"Give me your phone," she said, once she'd composed herself.

He handed it over without hesitation. She typed her number, saved it under her name, and passed it back. Their fingers brushed. His skin was warm.

"Now you can text me," she said. "Instead of stalking me in libraries."

"I wasn't stalking. I was... proactively locating."

"That's the worst euphemism I've ever heard."

"I have worse."

"I don't doubt it."

They sat there for a while, drinking coffee and not talking. The library breathed around them—pages turning, keyboards clicking, the faint whine of a vacuum on the floor below. Hervi's heart settled. Her shoulders dropped. She realized, with a start, that she wasn't embarrassed anymore.

Ced finished his coffee first. He stood up, stretched, and looked down at her with an expression she couldn't quite read.

"Office hours," he said. "Tomorrow. Nakamura's going to ask about the sample."

"I know."

"What are you going to tell her?"

Hervi thought about it. The truth was complicated. The truth was a locked room and a cracked vinyl chair and the taste of him still lingering in her mouth three days later. The truth was that she'd never done anything like that before, and she wanted to do it again.

"Nothing," she said. "I'll tell her nothing."

Ced nodded. He didn't push. He didn't ask for more.

"Good luck," he said.

Then he walked away, his footsteps fading into the carpeted aisles, and Hervi sat alone with her cold coffee and her racing thoughts and the index card she couldn't stop reading.

She folded it carefully. Tucked it into the back of her planner. Then she opened her textbook and tried to study, but the words swam on the page, and all she could think about was the way his hand had felt around hers, guiding her, teaching her, not judging her.

She closed the book.

Some things didn't need to be studied.

Some things needed to be lived.
