Kai's POV
Friday dragged.
Every class felt twice as long. Every minute stretched into an hour. I took notes, answered questions, participated in discussions. Went through the motions while my mind counted down.
One more day. Less than twenty-four hours.
Lunch was difficult. Ochako and Mina chatted about weekend plans while I nodded along, barely hearing them.
"Earth to Kai!" Mina waved her hand in front of my face. "You in there?"
"Sorry. Distracted."
"I'll say. You've been spacey all day." She leaned closer. "Got a hot date or something?"
"Something like that."
Her eyes widened. "Wait, seriously? Who?"
"Nobody you know."
"That's not fair! You have to tell me!"
"I really don't."
She pouted dramatically. "You're no fun, Hayashi."
Ochako watched the exchange with an expression I couldn't quite read. Curiosity, maybe. Or something else.
"Leave him alone, Mina," she said. "If he doesn't want to share, he doesn't have to."
"But I want to know!"
"Too bad."
Mina huffed but dropped the subject. I shot Ochako a grateful look. She smiled back, a little shy.
Afternoon classes were worse.
Nemuri's class was last period. Forty-five minutes of watching her move around the room, hearing her voice, smelling her perfume when she walked past.
She was talking about hero agencies. How they managed public relations, handled media, controlled narratives.
I barely heard a word.
All I could think about was tomorrow. Her apartment. No students, no teachers, no pretending.
Just us.
"Hayashi."
I snapped to attention. "Yes, Kayama-sensei?"
"I asked for your thoughts on agency branding strategies."
Shit. I hadn't been listening.
"I think..." I scrambled for something relevant. "Agencies need to balance authenticity with marketability. Heroes who seem fake lose public trust, but heroes who don't manage their image at all can be misrepresented by media."
Nemuri's eyes flickered with amusement. She knew I'd been zoning out.
"A fair assessment. Anyone else want to add to that?"
Other students chimed in. I exhaled slowly.
Close call.
The final bell rang.
Students packed up, chatting about weekend plans. Movies, arcades, training sessions. Normal teenage stuff.
I gathered my things slowly. Waited for the room to empty.
Nemuri was erasing the whiteboard, her back to the door. The last student left, closing it behind them.
We were alone.
"Cutting it close with that answer," she said without turning around.
"I was distracted."
"I noticed." She set down the eraser and faced me. "What were you thinking about so intently?"
"You know what."
"Maybe I want to hear you say it."
I stepped closer. "I was thinking about tomorrow. About finally being alone with you. About all the things I've been wanting to do for the past five days."
Her breath caught slightly. "And what things are those?"
"Kissing you. Touching you. Making you moan my name instead of calling me 'student.'"
"Kai..."
"I was thinking about how you looked in that costume yesterday. How it took everything I had not to drag you into a closet and—"
"Stop." She held up a hand, cheeks flushed. "You can't say things like that here."
"You asked."
"I didn't expect..." She took a breath, composing herself. "You're going to be the death of me."
"Hopefully in a good way."
She laughed despite herself. "Incorrigible."
"You love it."
"I do." She glanced at the door, then back at me. "Tomorrow. Ten AM. My apartment. Don't be late."
"I'll be early."
"Don't be too early either. I need time to prepare."
"Prepare what?"
Her smile turned wicked. "You'll see."
The walk home felt lighter.
One more night. That was all. One more night of waiting, then relief.
My phone buzzed.
Yu: Jealous that Nemuri gets you first.
You get me Sunday.
Not the same as Saturday.
It's exactly the same.
Liar. Saturday energy is different. Fresh from a week of buildup.
I smiled.
Sunday will be good too. Promise.
It better be. I've been thinking about you all week.
What kind of thoughts?
The kind that make work very distracting.
Tell me more.
Nope. You'll have to wait and experience it.
Cruel.
Learned from the best. Have fun tomorrow. Not too much fun though.
No promises.
Brat.
I pocketed the phone, still smiling.
At home, I tried to distract myself.
Homework. Training exercises. Cooking dinner. Cleaning my apartment.
Nothing worked. My mind kept drifting back to Nemuri.
Five days of seeing her at school. Five days of pretending we were strangers. Five days of watching her teach, smelling her perfume, hearing her voice.
Five days of torture.
Tomorrow it would end. At least for a while.
I showered and got into bed early. Tried to sleep.
Couldn't.
My phone buzzed.
Nemuri: Can't sleep either?
No.
I keep thinking about tomorrow.
Me too.
It's ridiculous. I'm a grown woman. I should be able to handle a few days apart.
But?
But I miss you. More than I expected.
I stared at the message. She wasn't usually this open about feelings.
I miss you too, I typed back.
This week was harder than I thought it would be. Seeing you every day, not being able to touch you...
I know.
I almost broke today. When you stayed after class. I wanted to kiss you so badly.
Why didn't you?
Because anyone could have walked in. Because we agreed to be careful. Because I'm supposed to be the responsible one.
Responsible is overrated.
Maybe. A pause. Tomorrow I won't be responsible at all.
Promise?
Promise. Now try to sleep. You'll need your energy.
For what?
Everything.
Saturday morning arrived slowly.
I was awake before my alarm. Showered, dressed, ate breakfast without tasting it.
Nine thirty. Time to leave.
The train ride felt eternal. Every stop taking too long, every delay making me twitch.
Finally, her station.
I walked the familiar route to her building. Up the stairs. Down the hallway.
Her door.
I checked my phone. 9:58.
Close enough.
I knocked.
The door opened.
Nemuri stood there in a silk robe, dark purple, loosely tied. Her hair was down, falling around her shoulders. No makeup, no costume.
Just her.
"You're early," she said.
"Two minutes."
"Still early."
"Want me to wait in the hall?"
She grabbed my shirt and pulled me inside.
The door slammed shut behind me. Her lips found mine before I could speak.
The kiss was desperate. Hungry. Five days of frustration pouring out all at once.
I grabbed her waist and pulled her against me. She moaned into my mouth, fingers digging into my shoulders.
"Missed you," she gasped between kisses.
"Missed you too."
"So much."
"I know."
Her hands found the hem of my shirt, tugging upward. I helped her pull it off, then went for her robe.
"Wait." She stopped my hands. "Not yet."
"Why?"
"Because I want to do this right." She stepped back, breathing hard. "I've been planning this all week."
"Planning?"
"Anticipation makes it better, remember?"
She took my hand and led me deeper into the apartment.
Her bedroom looked different.
Candles lined the dresser and nightstand, unlit but ready. The sheets were new, dark red silk. A bottle of wine sat in an ice bucket on the table.
"You decorated," I said.
"I wanted tonight to be special."
"It's morning."
"Don't ruin the moment with technicalities."
I laughed despite myself. "Yes ma'am."
She pushed me toward the bed. I sat on the edge, looking up at her.
"Five days," she said softly. "Five days of watching you in class. Seeing you laugh with those girls. Wanting to touch you and not being able to."
"I felt the same."
"I know. I could see it." She reached for the tie of her robe. "Do you know how hard it was? Staying professional while all I could think about was this?"
The robe fell open.
She wasn't wearing anything underneath.
"God," I breathed.
"Like what you see?"
"Always."
She let the robe slide off her shoulders, pooling at her feet. Stood there completely naked, letting me look.
Her body was perfect. Curves in all the right places, skin smooth and pale. I'd seen her naked dozens of times, but somehow it never got old.
"Touch me," she whispered. "Please."
I reached for her.
Nemuri's POV
His hands on my skin felt like coming home.
Five days. Five miserable days of pretending he was just another student. Watching him interact with those girls, seeing them smile at him, knowing I couldn't do anything about it.
Now he was here. Mine again.
I climbed onto his lap, straddling him. Felt his hardness through his pants.
"You're wearing too much," I murmured.
"Fix that."
I kissed him while working on his belt. He helped, lifting his hips so I could slide his pants down. Then his boxers.
Finally. Skin against skin.
"I thought about this constantly," I admitted, grinding against him. "In class, during meetings, lying in bed at night."
"What did you think about?"
"This." I rolled my hips, feeling him slide against my wetness. "You inside me. Filling me up."
"Nemuri..."
"I touched myself every night thinking about you." My cheeks burned admitting it. "It wasn't enough."
"Show me."
"What?"
"Show me what you did. How you touched yourself."
I stared at him. He was serious.
"I..." Nobody had ever asked me that before. "Okay."
I leaned back slightly, giving him a view. My hand slid down my stomach, between my thighs. Found my clit and started rubbing.
"Like this," I breathed. "I'd imagine your hands instead of mine."
"Keep going."
I rubbed faster, the familiar pleasure building. But it was different with him watching. More intense. Embarrassing and arousing at the same time.
"I'd think about your cock." My voice came out breathy. "How thick you are. How deep you go."
"And?"
"I'd finger myself pretending it was you." I slipped two fingers inside, gasping at the sensation. "But it was never enough. Never as good as the real thing."
"Show me how you made yourself cum."
I worked my fingers faster, rubbing my clit with my thumb. The pressure built rapidly, accelerated by his gaze.
"Kai... I'm close..."
"Do it. Cum for me."
"Fuck!"
The orgasm crashed through me. My pussy clenched around my fingers, my whole body shaking. I cried out, unable to hold back.
When it faded, I was trembling. He was still watching, his cock hard against my thigh.
"Beautiful," he said.
"I need you inside me. Now."
"Ask nicely."
"Please." I was beyond pride at this point. "Please fuck me, Kai. I need it so badly."
He lifted me, positioned himself at my entrance.
Then pulled me down onto his cock.
Kai's POV
She was so wet I slid in easily.
She cried out as I filled her, her walls clenching around me. Five days of buildup made everything more intense.
"God," she moaned. "I forgot how big you are."
"You didn't forget."
"No. But the memory didn't do it justice."
I grabbed her hips and started moving her. Slow at first, savoring the feeling of being inside her again.
"Faster," she demanded.
"Patience."
"I've been patient for five days."
"A little longer won't kill you."
"It might."
I kept the pace slow despite her protests. Long, deep strokes that made her gasp every time I bottomed out.
"Kai, please..."
"Please what?"
"Fuck me properly. Stop teasing."
"But you said anticipation makes it better."
She glared at me with hazy eyes. "I take it back."
I laughed and gave her what she wanted.
Nemuri's POV
He started pounding into me and I lost the ability to think.
All I could do was hold on as he thrust up into me, his hands gripping my hips hard enough to bruise. The sound of skin against skin filled the room.
"Yes!" I screamed. "Just like that!"
"You like that?"
"I love it! Don't stop!"
He didn't stop. Kept the brutal pace, driving into me over and over. I came again, harder than before, my vision going white.
"Cumming!" I cried. "I'm cumming!"
He fucked me through it. Didn't slow down even as I shook and screamed.
"More," I gasped when I could speak again. "Give me more."
"Greedy."
"You made me this way."
He flipped us suddenly. I was on my back, him looming over me.
"Better?"
"Yes."
He started moving again. Different angle now, hitting spots that made me see stars.
"I thought about this too," he said. "In class. Watching you teach."
"Yeah?"
"I imagined bending you over your desk. Making you scream while the whole class watched."
"Kai..."
"I imagined fucking you against the blackboard. Making you cum so hard you couldn't remember your own name."
"God..."
"Would you like that? Being fucked in front of everyone?"
The thought should have horrified me. Instead, it made me clench around him.
"Maybe," I admitted.
"Dirty."
"Your fault."
He laughed and kissed me. Kept moving inside me, slower now, deeper.
"I love you," he murmured against my lips.
"I love you too."
"I'm going to make you cum again."
"Yes."
"And again after that."
"Please."
"And you're going to scream my name every time."
"Yes."
"Say it now."
"Kai." I looked into his eyes. "Kai, please make me cum."
He smiled and started thrusting faster.
Kai's POV
I made her cum four more times.
By the end, she was a trembling mess. Tears streamed down her face, her voice hoarse from screaming. The sheets were soaked with sweat and other fluids.
"I can't," she whimpered. "Too much."
"One more."
"I can't!"
"You can."
I was close myself, holding back through sheer willpower. I wanted to finish inside her, feel her clench around me one final time.
"Kai, please..."
"Cum with me." I thrust deeper, harder. "One more time."
"I can't, I can't, I—"
She screamed as another orgasm ripped through her. I felt her walls spasm around me and let go.
"Fuck!"
I slammed deep and came. Rope after rope of cum flooding into her. The essence transfer activated, energy flowing between us.
"Yes!" she cried. "Fill me up!"
I kept cumming. More than seemed possible. She took all of it, her pussy milking me dry.
When it finally stopped, I collapsed beside her.
We lay there gasping, tangled together, too exhausted to move.
"Holy shit," she breathed.
"Yeah."
"That was..."
"Yeah."
She laughed weakly. "We should do the anticipation thing more often."
"Maybe not five days though."
"Definitely not five days."
We lay in comfortable silence for a while.
Her head on my chest, my fingers tracing patterns on her back. The candles she'd set up remained unlit, forgotten in our urgency.
"I'm sorry about the candles," she said. "I had a whole romantic setup planned."
"This was better."
"Really?"
"Really." I kissed her forehead. "I don't need candles. I just need you."
She made a soft sound and snuggled closer.
"The week was hard," she admitted. "Harder than I expected."
"For me too."
"Seeing you with those girls..." She hesitated. "Yaoyorozu looks at you like you hung the moon. And Uraraka blushes every time you talk to her."
"They're classmates."
"They're interested."
I couldn't deny that. "Maybe."
"It bothered me more than I thought it would." She propped herself up to look at me. "I'm not usually the jealous type."
"Are you jealous?"
"A little." She bit her lip. "Which is stupid. I knew what I was getting into. Your quirk, your situation. I accepted all of it."
"But?"
"But watching it happen is different than knowing about it in theory."
I pulled her closer. "You're still my first. That matters."
"Does it?"
"It means everything." I held her gaze. "Whatever happens with anyone else, you'll always be the one who started this. Who believed in me before anyone else did."
"Even Mt. Lady?"
"Even Yu."
She was quiet for a moment. Then she smiled, some tension leaving her shoulders.
"Okay."
"Okay?"
"Okay, I believe you." She kissed me softly. "Just... don't forget about me. When your harem grows. Don't let me become just another name on the list."
"Never." I cupped her face. "You're not a name on a list, Nemuri. You're the woman I love."
"One of the women."
"The first one. The one who matters most."
Her eyes glistened slightly. "You always know what to say."
"I mean every word."
She kissed me again, deeper this time. I felt her body respond, pressing against mine.
"Ready for round two?" she murmured.
"Already?"
"I've been waiting five days." She climbed on top of me. "We're not done yet."
We weren't done until evening.
Six rounds total. Different positions, different rhythms. Sometimes fast and desperate, sometimes slow and tender.
By the time we finally stopped, the sun was setting outside her windows.
"I can't feel my legs," she announced.
"Mission accomplished."
"Brat." She swatted my chest weakly. "What time is it?"
"Almost seven."
"We've been at it for nine hours."
"With breaks."
"Small breaks." She laughed. "I'm going to be walking funny for a week."
"Good. Something to remember me by during class."
"Like I could forget." She stretched, wincing slightly. "I need food. And a shower. Possibly in that order."
"I'll cook."
"You cook?"
"Yu taught me."
"Of course she did." She smiled. "Fine. Cook for me while I shower. Then maybe we can go again."
"Again?"
"What? I have stamina."
"Clearly."
I made pasta while she showered.
Simple stuff, but filling. She emerged wrapped in a towel, hair wet, skin pink from hot water.
"Smells good."
"Thanks."
We ate on her couch, plates balanced on our laps. Comfortable. Domestic.
"This is nice," she said between bites.
"The food?"
"All of it. Cooking together. Eating together." She leaned against me. "We don't get to do this often enough."
"No. We don't."
"Maybe after you graduate..." She trailed off.
"Maybe."
Three years. A long time to wait. But not forever.
"I should probably go eventually," I said.
"Do you have to?"
"I have homework. And I promised Yu tomorrow."
"Right." She set down her plate. "I knew that."
"Are you okay?"
"Fine. Just..." She sighed. "I want to be selfish. Keep you here forever."
"The weekend isn't over yet."
"But tomorrow you'll be with her."
"And next weekend I'll be with you again."
She nodded slowly. "I know. I'm being stupid."
"You're being human." I pulled her closer. "It's okay to want more. Just know that I'm not going anywhere."
"Promise?"
"Promise."
She relaxed against me. "Stay a little longer?"
"Always."
I left around midnight.
She walked me to the door in her robe, looking thoroughly satisfied and slightly sad.
"Text me when you get home."
"I will."
"And text me tomorrow. Even if you're with Yu."
"I will."
"And don't forget about me during the week."
"Never."
She kissed me one last time. Long and slow and full of meaning.
"I love you."
"I love you too."
"See you Monday. In class."
"See you Monday, Kayama-sensei."
She shivered. "I hate that I like it when you call me that."
"I know." I grinned. "That's why I do it."
"Brat."
"Your brat."
"Yes." She touched my face. "My brat. Now go before I drag you back to bed."
I went.
The train home was nearly empty.
I sat by the window, watching the city lights blur past. My body was exhausted but satisfied. The tension of the week had finally released.
My phone buzzed.
Yu: How was it?
Intense. Nine hours.
Damn. She must have really missed you.
She did.
Well, I hope you saved some energy for tomorrow.
I'll manage.
You better. I have plans.
What kind of plans?
The kind that involve you not leaving my apartment until Monday morning.
That's ambitious.
I'm an ambitious woman.
I smiled and pocketed the phone.
Tomorrow would be just as intense. Maybe more.
But tonight, I needed sleep.
I got home, showered, and collapsed into bed.
For the first time in five days, I slept soundly.
