Work Text:
Utahime was assigned to investigate the deaths of seven high-profile government officials, all connected to an exclusive establishment known only as Maison Kiku. She had prepared for three days, memorizing floor plans, studying the victims' profiles, and coordinating with Kusakabe, her assigned partner.
So when Gojo appeared at the rendezvous point instead, she felt her eye twitch.
"Yo."
"No," Utahime said flatly.
"Good evening to you too, Utahime."
“It’s Utahime-sen—” She stopped, exasperated. “Ugh. Forget it. Where’s Kusakabe?”
“Last-minute changes from HQ.” He pulled out his phone, waggling it at her. “Kusakabe got reassigned to a Grade 1 situation in Sendai. Lucky you~ you get an upgrade. Apparently they needed someone with more… finesse for this particular job.”
"Finesse? You?" She scoffed. "You wouldn't know finesse if it hit you in your stupid blindfolded face."
“Aw, you wound me.” He clutched his chest dramatically, then slipped the blindfold off and traded it for a pair of dark sunglasses. “And here I thought we’d have fun playing house together.”
“They couldn’t have told me?”
“Where’s the fun in that?” He stopped in front of her. “Besides,” he added, “you should be grateful. I’m much better company.”
“That’s debatable.” She crossed her arms. “Thank you, but I’ll do this alone.”
“Can’t.” He rocked back on his heels, grin widening. “Mission parameters require a couple. Two people checking in together. You know, together together.”
Utahime pinched the bridge of her nose.
Three years. She’d managed to avoid partnering with Gojo for three whole years since he’d graduated.
Her streak was officially broken.
"Did you even read the briefing?" she demanded.
“Exclusive sex club, mysterious deaths, rich people dying with their pants down. Literally." He shrugged. "Pretty straightforward."
"It's not just any hotel. Maison Kiku caters to politicians, CEOs, celebrities. Seven deaths in two months, all during... activities. The government wants this handled quietly."
“Which is why the police are already involved,” Gojo said lightly. He showed her the confirmation on his phone. “But they can’t deal with curses. Hence sending us. I already made our reservation— Mr. and Mrs. Yamamoto. Just married, looking to spice things up.”
Utahime snatched the phone. "You made us married?"
"Would you prefer siblings?"
She shoved the phone back at him. "Fine," she said through gritted teeth. Going back to HQ and requesting a different partner would waste time. More people could die. And as much as she hated to admit it, if there was a special grade curse involved, having Gojo wasn't the worst option.
It was just the most annoying one.
“But you follow my lead,” she added sharply. “This requires subtlety. Do you even know what that word means?”
"I've heard of it.”
"That's not reassuring."
****
Maison Kiku occupied several of the upper floors of what appeared to be an ordinary luxury hotel in Roppongi. From the outside, nothing distinguished it from the dozens of other high-end hotels lining the district. Access, however, required three separate codes and a referral from an existing member. Jujutsu HQ’s intelligence division had secured all of it; the government was desperate enough to provide whatever access was needed.
The elevator climbed higher than she expected. Utahime adjusted the strap of her black dress, a designer piece requisitioned specifically for the mission.
Beside her, Gojo looked aggravatingly at ease in a fitted white button-down, sleeves rolled to mid-forearm to flaunt lean muscle and those annoyingly elegant hands, his white hair artfully tousled above dark sunglasses.
"Stop fidgeting,” he said. “You look good.”
“I’m not fidgeting.”
“You’ve adjusted that strap four times.”
“I’m making sure it stays in place.”
“It’s not going anywhere.”
The elevator doors opened.
The aesthetic shifted immediately: warm amber lighting, black marble floors, the faint scent of bitter incense with perfume and skin beneath it— money and desire, architecturally rendered.
The reception area resembled a five-star hotel lobby, except the art on the walls was explicitly erotic and the staff wore fitted black outfits that left strategic details to the imagination.
“Welcome to Maison Kiku.” The receptionist’s voice was honey-sweet, and she nearly melted under Gojo’s smile. “Checking in?”
“Reservation under Yamamoto,” Gojo said smoothly, sliding an arm around Utahime’s waist. She stiffened but didn’t pull away.
He handled the check-in with an ease that made Utahime wonder exactly how familiar he was with places like this.
“Of course, sir. The Chrysanthemum Suite is ready. Excellent choice.”
As the receptionist processed their booking, two other staff members near the back desk kept stealing glances. Their whispers carried easily through the quiet lobby.
“—God, he’s gorgeous. Did you see his watch? That’s a Patek Philippe. He must be loaded.”
“—maybe he lost a bet—”
“—that scar though. Maybe she’s good in bed. Like, really good. Rich guys have weird tastes—”
They dissolved into mean giggles.
“—probably takes her from behind and puts a bag over her head—”
“—or makes her wear a mask so he doesn’t have to look—”
Utahime kept her expression neutral. Seven years since the incident. She’d heard worse. The scar across the right side of her face was impossible to hide without illusion techniques she refused to waste cursed energy on. She had made peace with it. Most days.
Gojo’s hand had gone still on the counter. His head turned, almost imperceptibly, toward the whispering women.
The ambient temperature in the lobby dropped by exactly one degree. Utahime had worked with him long enough to recognize the micro-fluctuation of Infinity engaging— not as a barrier, but as instinct. The way a predator’s hackles rise.
“Gojo,” she said quietly.
He didn’t look at her.
“Darling.” She placed a hand on his arm. His muscle was taut beneath the fabric.
“Focus. Don’t cause a scene,” she whispered.
A moment passed. Then the tension dissolved. He turned back with a wide, dazzling smile that made the women blush immediately.
The receptionist handed over their keycard. “Room 2012. If you require any additional services, your personal concierge is available, just dial the number listed beside the phone in your suite. Enjoy your stay.”
“Thanks so much,” he said brightly. “You’ve been super helpful.”
He turned and walked toward the elevator bank, Utahime beside him.
Neither of them spoke until the doors closed.
“I could have made them cry,” he said mildly.
“I know.”
“I could have shut them up for good.”
“I said I know.” She exhaled quietly. “It doesn’t matter. I’ve heard worse.”
He leaned back against the elevator wall and looked at her.
“It matters,” he said. “And I don’t like stupidity. They were special-grade stupid.”
The elevator opened before she could respond.
****
Room 2012 was obscene.
Not in a tasteless way. The suite was expansive: a main room with a California king bed dressed in black silk, ambient lighting adjustable from cool white to deep red, and an entire wall that was currently opaque, but according to the control panel beside the door— could be made transparent, offering a direct view into the adjacent suite. For exhibitionists. And voyeurs.
The bathroom held a shower large enough for four people, a freestanding tub, and a locked cabinet that Utahime opened with a simple lock-picking technique. Inside was an assortment of equipment she scanned with professional detachment.
“Ropes, restraints, blindfolds… standard issue for this kind of place,” she reported. “Some things I don’t recognize. And don’t want to.”
“The minibar has high-end champagne and what I’m pretty sure are edibles,” Gojo called from the main room.
“Don’t eat them,” she said.
“I wasn’t going to eat them. I have standards.”
“Since when?”
Utahime finished her sweep of the bathroom and returned to the main room.
Gojo sat on the edge of the bed, leaning forward with his elbows on his knees, chin resting on his clasped hands. The posture made him look simultaneously casual and calculating.
“Residuals are stronger in the upper floors,” he said. “Whatever’s killing people, it’s territorial.”
Utahime extended her senses. He was right. The cursed energy was thicker here, woven through the walls.
“It’s ambient,” she said. “Not localized to a single point. Which means it’s either very old or—”
“Or it doesn’t manifest physically until triggered by something.”
“By what, though? All seven deaths happened in different rooms. Different floors. Different dates and times. The only common factor—”
A moan cut through the wall. Low. Throaty. Clearly sexual.
Another followed from the opposite wall— higher, breathier.
Then came a rhythmic thumping that required no interpretation.
The soundproofing, apparently, was not a priority at Maison Kiku.
Utahime felt heat crawl slowly up her neck.
From multiple rooms on their floor— above and below— the sounds of people using the establishment as intended filtered through the walls: gasps, groans, and the occasional sharp cry forming a layered soundtrack.
Gojo hadn’t moved. He stayed perched on the bed in that same calculating posture, a slow smirk spreading across his face.
“Well,” he said.
“Shut up.”
“I haven’t even said anything yet.”
“You were about to.”
“I was just going to observe that you’re turning a very interesting shade of—”
“I said shut up.”
Utahime sat stiffly in the armchair across from the bed, arms crossed, staring hard at the wall as if she could will it into silence.
She could not.
Someone in 2013 was having a very enthusiastic evening.
“You know,” Gojo said, “for someone on a mission in a sex hotel, you’re remarkably uptight.”
“And for someone on a mission in a sex hotel, you’re remarkably comfortable.” She shot him a look. “Do you just hang out in places like this regularly?”
“Nothing fazes me. It’s a gift.”
“It’s a personality disorder.”
He grinned.
The moaning intensified. Utahime glared at the wall.
"Can you put Infinity over the walls or something? Block the sound?"
"I could. But then I'd also block the cursed energy fluctuations I'm monitoring. Which would defeat the purpose of us being here."
"Of course."
A particularly theatrical cry echoed from somewhere down the hall. Gojo tilted his head.
"Seven out of ten," he said.
"You are not rating them."
"You're right. That was generous. Five."
Utahime pressed her fingers to her temples. "I cannot believe HQ sent you."
"Would this be less awkward with Kusakabe?"
"Significantly."
"Ouch."
"He would at least have the decency to be equally uncomfortable."
"Who says I'm not uncomfortable? Maybe this is my uncomfortable face."
"That is your 'I'm enjoying making someone else miserable' face. I've seen it for eight years."
He considered this. "Fair.”
A silence fell between them, filled immediately by the ambient sounds of the floor above. The cursed energy stirred. Utahime tracked it, trying to find a pattern.
"Can I ask you something?" Gojo said.
"Can I stop you?"
"Does this kind of thing actually make you uncomfortable, or is it just the context?"
She looked at him. His expression was unreadable— genuinely curious, maybe, or maybe just probing for ammunition.
"The context," she said carefully. "Being in a sex hotel with you, investigating deaths that apparently happen during sex, while listening to a live surround-sound demonstration— yes. That's a specific kind of uncomfortable."
"But not the concept generally?"
"What are you asking me, Gojo?"
He leaned back on his hands, casual, but his eyes stayed sharp. "I'm asking if Utahime Iori has experience in the field we're currently investigating."
"You're asking about my sex life."
"For the mission."
"How is my sex life relevant to the mission?"
"Because—" He sat forward again. "Every victim died in a VIP suite. During sex. The cursed energy here is ambient but it spikes— I can feel it even now, the fluctuations track with what's happening in the rooms around us. It's feeding on something. And if that something is what I think it is, then understanding the mechanism matters."
She studied him. He was, underneath the insufferability, actually brilliant. She hated that.
"You think it feeds on arousal? On orgasm specifically?"
"I think it feeds on the peak. The moment of climax. Maximum vulnerability, maximum release of emotional and physical energy. Every victim died at or near the point of orgasm— the autopsy reports are consistent with sudden fatal arrest at the moment of highest physiological intensity."
Utahime processed this. "A curse that triggers during climax. That's... specific."
"This place has been running for years. Thousands of people cycling through, all generating concentrated emotional and physical energy— desire, lust, pleasure, shame, power, submission. That's a lot of raw material for a curse to gestate in."
"A special grade?"
"Has to be. The residuals are too dense for anything less. And it's smart— it only kills occasionally. Selectively. If it killed everyone, the place would have shut down years ago. It feeds continuously on the ambient energy, but when it manifests—"
"It kills at the peak," Utahime finished. "When the energy output is highest. Maximum feeding."
"And then it goes dormant again. Which is why there's no consistent entity to track. It exists in the building— in the walls, the infrastructure. It only takes form for the kill."
"So we need to make it manifest."
The implication hung in the air between them.
Gojo's expression was perfectly neutral, almost aggressively so. Whatever he was thinking was locked behind those blue eyes.
“We should investigate the other floors first," Utahime said. “Map the residual concentrations. Check the rooms where the deaths occurred."
"Agreed."
****
They spent the next three hours doing exactly that, posing as guests "exploring the amenities" while systematically surveying every floor.
The cursed energy flowed everywhere in the same pattern. Gojo mapped it instantly, his Six Eyes perceiving what no other sorcerer could.
“It’s one entity,” he confirmed as they returned to their suite at midnight. “Distributed through the building’s structure. But the concentrations spike on the twentieth and twenty-first floors.”
“The most expensive suites,” Utahime said.
“The most powerful clients,” Gojo replied. “People whose deaths generate more fear and secrecy. More cursed energy fed back into the system.”
Utahime frowned slightly. “It’s a cycle. It selects high-value targets because their deaths generate more fear. More negative feelings feeds the curse.”
“Exactly.”
Gojo sat on the bed again. That same posture— elbows, knees, chin on hands. His eyes tracked something Utahime couldn't see.
"I can see it," he said quietly. "With the Six Eyes. It's in the walls. Like veins. The whole building is its body."
"Can you exorcise it from here?"
"Not while it's distributed. It's too diffuse— hitting it now would be like trying to punch fog. I need it to condense. To manifest."
"Which it only does—"
"At the peak."
Utahime sat in the armchair. The sounds from adjacent rooms had quieted somewhat— it was late, even for this place. The cursed energy continued its steady flow.
"There might be another way," she said. "If I use my technique— my voice can amplify and modulate cursed energy. I might be able to agitate it, force it to condense without the... trigger."
"Maybe. But it's had years to entrench itself. Your technique would need a starting resonance to amplify. Something to tune to."
"The ambient energy from the other rooms—"
"Is tapering off. It's midnight on a Tuesday. The building's emptying out." He looked at her. "Utahime."
"Don't."
"I haven't said anything yet."
"You're about to suggest that we provide the trigger ourselves and I'm telling you—"
"I'm suggesting that two of the most capable sorcerers in Japan are in a room with a special grade curse that we can't exorcise unless it manifests, and we have exactly one reliable way to make it manifest."
"By having sex."
"By generating enough concentrated energy at a high enough peak to draw it out. And then killing it."
The clinical way he said it almost made it sound reasonable. Almost.
"We could die," Utahime said. "The peak is when it kills."
"I have Infinity. Nothing touches me unless I let it."
"The other victims didn't think they'd die either."
"The other victims weren't me."
It wasn't arrogance— or rather, it was, but it was also fact. Gojo could maintain Infinity autonomically, even during sleep. The curse couldn't reach him physically. And if it manifested, his Domain Expansion would end it in 0.2 seconds.
"You'd be more vulnerable," he said, and then carefully, he added, "I'd need to extend Infinity to cover you at the moment of manifestation. Which I can do. But it means—"
"It means you'd need to be touching me."
"Yes."
The word sat between them.
"This is insane," Utahime said.
"Most of what we do is insane. This just has a different hat."
She didn't laugh. She looked at him, past the smirk and the posture and the carefully constructed persona of the invincible, untouchable strongest. His jaw was tight. The muscle in his forearm was tense.
"If we do this," she said slowly, "it's a tactical decision. For the mission."
"Obviously."
"And you will never, ever mention it to anyone."
"Who would I tell?"
"Shoko."
“She’d think it was funny."
"She’d think it was tragic, because it involves me having to see you naked."
"You say that like it's a punishment and not a reward."
"It is a punishment. Everything involving you is a punishment."
He smiled. Softer than his usual grin. "Come here, Utahime."
She didn't move. "The logistics. Talk me through it."
"The curse needs a genuine peak to manifest. It's been feeding on real human energy— it'll know if we fake it. So—"
"So it has to be real."
"Yes. And I'll need to maintain physical contact with you to extend Infinity at the critical moment. Which means—" He paused, carefully choosing his words. "Which means I need to be facing you. Looking at you. Close."
Something in his tone made her stomach tighten.
"When it manifests, I'll need one point three seconds to deploy Unlimited Void. During that time, Infinity covers both of us. It can't touch us. I collapse it, exorcise it, done."
"One point three seconds."
"I've done it faster."
"You've never done it during—"
"No. But I'm a fast learner."
****
They prepared the room. Utahime set cursed energy markers at the four corners— her technique would let her detect the exact moment the curse began to condense, giving Gojo additional warning. She drew barrier seals on the walls with a felt-tip pen from her bag, reinforcing the room against energy spillover.
Gojo stood at the edge of the bed. “You can leave the lights off if you want,” he said, neutral, almost testing.
"Why would I?"
"Some people prefer it."
She lifted her chin. “You don’t think I’m attractive enough to look at?”
"That's not—" He ran a hand through his hair. "Utahime, this isn't about attraction."
"Then what?"
"You hate me."
"I don't hate you. You're annoying, arrogant, and impossible, but I don't hate you."
"That's not exactly a ringing endorsement for sex."
"It doesn't have to be good. It just has to work."
He laughed, sharp and humorless. "You really think I'd be okay with bad sex? With you just... enduring it?"
"Then make it good."
The words hung between them. The room felt smaller suddenly.
"You don't know what you're asking," he said quietly.
"I know exactly what I'm asking. The question is whether you can handle it."
His eyes sharpened. "Is that a challenge?"
"It's a mission parameter."
He moved closer, and she held her ground. "And after? When this is over?"
"We go back to normal."
"Normal." He was close enough that she could smell his cologne. "You think we can just pretend."
"You're good at pretending."
"Am I?" His hand came up, fingertips barely grazing her scarred cheek. "Those women at the desk. They were very wrong."
"Gojo—"
"You're beautiful." He said it simply. "The scar doesn't change that. Never has."
"You don't have to—"
"I'm not good at this," he interrupted. "The talking part. Usually, I just... don't."
"Then don't."
She kissed him.
Or maybe he kissed her. It was genuinely unclear who moved first. One moment they were standing beside a silk-covered bed in a luxury sex hotel with a special-grade curse in the walls, and the next her hands were in his hair, his arm around her waist, his mouth on hers— and it was nothing like she’d expected.
She'd expected him to be aggressive.
This wasn't.
He kissed her slowly and carefully. His hand stayed on her waist— firm but not gripping, holding but not trapping. When she opened her mouth against his, he made a sound against her lips, and it was so un-Gojo, that it made her dizzy.
"This is weird," she murmured against his mouth.
"Extremely weird," he agreed, and kissed her deeper.
"You know what I mean. We argue constantly. You drive me crazy. You're insufferable and—"
"And you're stubborn and hot-tempered and absolutely gorgeous when you're angry," he cut in. "Which is most of the time around me. But I'd be lying if I said I'd never thought about it."
That stopped her short. "You've thought about this?"
"More than I should admit." His thumbs stroked her cheekbones.
He took his shirt off and Utahime took a moment to appreciate the view. She'd known he was fit, it was hard not to notice even through his uniform– but seeing him like this was different.
"See something you like?" The teasing was back in his voice.
"Don't push it." She ran her hands over his chest.
His thumb slipped lightly under the strap of her dress. “Guess this thing’s coming off after all.”
She rolled her eyes. “Stop talking.”
He reached for the zipper of her dress, and he drew it down slowly, letting the fabric pool at her feet. His gaze traveled over her.
"Beautiful," he murmured again, appreciative.
She felt exposed, vulnerable, and powerful.
He lowered her onto the bed. The sheets were cool silk against her back. He hovered over her, weight on his forearms, and she could feel the hum of Infinity like a second skin around him— except where he touched her.
The significance of that wasn't lost on her. She'd studied Limitless extensively— knew that Infinity was autonomic, instinctive, the ultimate defense mechanism. For Gojo to selectively disable it at points of contact, he had to consciously choose to be vulnerable.
He was choosing that. With her.
When she reached instinctively to angle her scarred cheek away from the light, he caught her chin and turned her face gently back toward him.
"Don't," he said.
"Force of habit."
"Bad habit." He kissed the scar. His lips tracing the line of it from her cheek to her nose. Unhurried.
“I want to see your face. Especially when I do this—"
He kissed her neck, finding a spot that made her gasp.
"And this—"
His hands skimmed her sides.
"Gojo—"
"Satoru.” he corrected. "If we’re doing this—" He unclasped her bra with a deftness that she filed away to interrogate him about later. "Use my first name."
"Satoru." It felt strange on her tongue. Strange but right.
"Hm." He pulled back to look at her. "That sounded good."
"Don't get used to it."
"Too late."
More clothes joined the floor. He trailed kisses down to her sternum to find another scar. "You have a lot of these."
"Occupational hazard."
"I don't have any."
"You have Infinity."
"Mmhm. Sometimes I wish I did." His mouth found her breast, derailing that line of conversation entirely. "I want evidence that I lived through things.”
"You want scars?"
"I want marks that matter." He looked up at her. "I want to see you. All of you. Every time. No hiding. If that's what those women think we do, they have no imagination."
"Stop talking about them."
"Gladly.” He pressed a kiss to her inner thigh. “I have better uses for my mouth."
He proceeded to demonstrate.
"You're—" She gasped as his mouth found its destination. "You're— oh— adequate."
He laughed, and it was the best sound she'd ever heard. "Adequate? I'll show you adequate."
"That's not the threat you think it— oh."
He was, as it turned out, considerably better than adequate. His tongue was clever, his fingers more so, moving with the same perfect, devastating competence he brought to everything. She felt like a technique being deconstructed. Utahime had stopped thinking about scars or lights or any of the defenses she’d built over the years.
“I can feel the curse,” he murmured. “It’s agitated. The energy in the room is spiking.”
She extended her senses. He was right; the cursed energy in the walls had shifted from its steady pattern to something faster and hungrier. It was responding to them.
“Good,” she breathed. “Let it come.”
She arched into his hand, his mouth moving in sync, and the seals on the walls glowed faintly in her peripheral vision as the cursed energy spiked again.
“Look at me,” he said.
She opened her eyes. He was watching her face, cataloguing every micro-expression, seeing her completely, with the same perception that let him see the atomic structure of cursed energy.
Nobody had ever looked at her like that.
"The energy's condensing," she managed. "In the wall behind you. Upper left quadrant. It's— it's starting to take form—"
"I know. I see it. Not yet. It won't fully manifest until—"
"Until the peak. I know. We discussed this. Can you— more—"
"More what?"
"More you. More— don't make me say it—"
"I want to hear you say it."
"I hate you. More. Please. I need—"
He kissed her, swallowing the rest of the sentence, and shifted his position. When he finally entered her, the sound she made was embarrassingly loud and she didn't care. He was bigger than she'd expected— not that she'd expected anything, not that she'd thought about it— and the stretch was intense but not unwelcome.
The cursed energy in the walls erupted.
"Still okay?"
"Yes."
"There," he breathed. "It's moving. Starting to condense in the corner."
She wrapped her legs around him. The angle changed and they both made sounds that would have been deeply undignified in any other context. His forehead dropped to hers.
"Utahime—"
"I know. I can feel it too."
The room had changed. The walls glowed brighter as dark veins of cursed energy converged above and behind Gojo’s left shoulder. Something was forming— indistinct, heavy, a knot of something dark drawing itself together like a fist clenching.
Gojo moved inside her— controlled, relentless, his eyes never leaving hers. One hand braced beside her head, the other on her hip, and she could feel Infinity tightening around them both.
"It's almost corporeal," he said. His voice was strained— the only sign that maintaining Six Eyes perception, Infinity extension, and this pace simultaneously was taxing even him. "Upper left. Two meters. When it fully manifests—"
"I'll hit it with my technique first. Amplify its energy past what it can contain. Force it to overextend."
"And then I collapse it."
"Yes."
"You'll need to time it exactly."
"I know."
"You'll need to be at— we'll both need to—"
"Satoru." She held his face in both hands. "Shut up and focus."
He thrust deeper. She gasped. The curse vibrated more violently in response.
The escalation felt terrifyingly natural— the mission and the physical reality converging into one rising wave. Her technique hummed in her throat, ready to deploy. His Infinity tightened around them. And beneath it all was the overwhelming fact of him inside her, above her, looking at her like she was the only thing in the world worth seeing.
She felt the peak building, intensifying, inevitable.
"Now," she whispered.
"Not yet. Almost— it's at ninety percent formed—"
"Satoru, I can't— I'm going to—"
"Wait—"
The curse manifested fully. It was a massive, writhing, humanoid shape— mouth open in a silent scream, reaching for them with hands designed to reach inside a human body at its most vulnerable moment and squeeze—
Utahime hummed. One note. Perfect pitch, perfect resonance, amplifying the curse's own energy back into itself like feedback through a speaker. The entity swelled, bloated, its form destabilizing—
Gojo’s hands left her, fingers forming the familiar sign. His eyes were infinite— blue fractals of perception and power— and he said quietly:
"Domain Expansion."
The world went black.
Unlimited Void lasted 0.3 seconds— a merciful brevity. The curse received the infinite information of Gojo's domain and shattered.
The room snapped back to normal. The cursed energy in the walls evaporated. The seals flared and went dark.
Gojo braced himself over her, and looked down.
"Hi," he said, slightly breathless.
"Hi," she said, very breathless.
"It's dead."
"I noticed."
…
"We didn't— finish," he said.
…
"I noticed that too."
"The mission's technically over."
"Technically."
He was still inside her, and still hard. His hair was damp and falling into his eyes and he looked wrecked in a way that the strongest sorcerer in the world was never supposed to look.
"If we continued," he said carefully, "it wouldn't be for the mission."
"No."
"It would be because I want to."
She touched the side of his face. He leaned into it— an involuntary motion, almost feline. "It would be because I want to, too."
He smiled.
He started moving again.
Without the tactical overlay, without the mission calculus, it was different. Slower. More.
"Keep your eyes open."
"That's—"
"Please."
The word stopped her protest. He didn't say please often, if ever. She nodded, holding his gaze.
She could see every reaction on his face— the way his jaw clenched when she tightened around him, the flutter of his lashes when she rolled her hips to meet his thrust, the almost pained expression when she raked her nails down his back.
"Utahime… You feel—"
"What?"
"Perfect." He buried his face in her neck, hips stuttering. "Too perfect. I'm not gonna last—"
"So don't."
She wrapped her legs around him, urging him deeper, faster. He groaned against her skin, all pretense of control abandoned. His hand slipped between them, finding her clit.
"Together," he managed. "Want you to—"
She did, the orgasm crashing over her just as he lost himself inside her.
Afterward, he didn't immediately pull away. He stayed inside her, softening slowly, pressing kisses to her shoulder, her jaw, her scarred cheek. Then he looked at her and said:
"Ten out of ten."
She shoved him off the bed.
****
They drove back in the early hours of the morning. Gojo was at the wheel.
"The mission report," she said.
"Special grade curse, semi-autonomous, gestated from ambient cursed energy in a high-density emotional environment. Exorcised via combined technique: Cursed song amplification and Domain Expansion. Zero casualties."
"And the method of manifestation trigger?"
"Classified."
"Classified."
"Deep cover tactical operation. Details restricted to participating agents."
She looked at him. He was wearing his sunglasses again, but she could see the corner of his mouth curved upward.
"This doesn't change anything," she said.
"Of course not."
He reached across the center console and took her hand. She let him.
They drove through the empty predawn streets of Tokyo, bickering about anything, and the mission report would say nothing about the way his thumb traced circles on her palm, or the way she didn't pull away, or the way the strongest sorcerer in the world drove one-handed all the way back to Kyoto because he wouldn't let go.
It would say: Mission complete. Curse exorcised. No casualties.
It would not say: Ten out of ten.
Some things stay classified.
