Yuji caressed her arms, then slid his hands to her breasts. He massaged them with a slow, lingering touch before lifting her lavender bra to bare them. He closed the distance, kissed her breasts, his gaze locked on those deep blue eyes he always lost himself in. She breathed slowly but deeply, stroked his soft hair and looked up at him, biting her lower lip.
"Oh, Yuji...I need you...inside me...mmm.."
He didn't answer, he looked at her as if she were the most beautiful thing he'd ever seen. Aiko arched her back, ran her fingers through her hair and pulled it forward, biting her lip. Her beautiful blue eyes stayed on him.
"Oh my God, she's so sexy..." Yuji narrowed his eyes, savoring the sensation, wanting to feel those hard, smooth nipples even more.
She moved a little further back and knelt before him.
"Yuji... I want you in my mouth... please, fuck my mouth..."
She said, her hands already on the waistband of his pants. She moved a hand between his legs, felt his size, and massaged him thoroughly.
"So… are you going to fuck my mouth?" she asked, as she touched him.
Yuji's gaze was hungry, full of lust. Yet he didn't respond.
She leaned closer and kissed him over his pants, massaging it slowly with her teeth.
His pants were pulled down forcefully, along with his boxers. Yuji stood before her gorgeous and enormous, throbbing with pleasure. Aiko opened her mouth and closed it over him, moving up and down with slow movements, sucking, trying to remain as discreet as possible.
He bit his lip on the inside, raised both hands above his head, then the back of his right hand to his forehead, squeezing his eyes shut in pleasure.
"Oh, Aiko..." he said, panting.
She increased her pace, faster and faster. Aiko slid a hand around him to hold him steady, while Yuji drew her closer, his palm cradling the back of her head as he stroked her hair. He pushed her deeper and deeper and Aiko responded to his touch and took him deep into her throat, never complaining. She kept going like that for a while, until Yuji finally lost patience. He couldn't take it anymore... he grabbed her face in his hands to hold her still: he started and moved faster.
"Oh Aiko... I'll put it all the way down your throat..." he said, while fucking her mouth.
Aiko's tears welled up in her eyes, wanting more and more. She wanted to hear him cum.
"Yuji's moans are so beautiful...and they're all mine." She thought, placing both hands on his thighs to steady herself.
Just the thought of having that power over him—of driving him wild with desire, of giving him sensations that overwhelmed him, of making him feel pleasure so intense it could break him in two—sent a shiver down her spine. It made her feel alive. More of a woman. Desired in every gesture, in every look. Wanted as she had never been before.
At a certain point, however, Yuji grabbed her arm and pulled her up. She turned and leaned forward of her own accord, laughing. He entered her easily, grabbed her wrists and began pounding her violently. Aiko moaned loudly, completely wet. Juice was dripping down her thighs.
"Oh, Yuji... fuck me li-ke this..." she said, extremely excited.
He increased his thrusts even more, his thrusts coming one after the other, mercilessly. Aiko came after just a few seconds, crying out with pleasure, her head thrown back, tears in her eyes. Yuji felt her trembling all over, her orgasm so intense, he couldn't resist any longer.
"Aiko, kneel down" he exclaimed, stepping out. She obeyed.
He came on her breasts, even splashing a little on her face. She looked up at him, smiling, her chest completely smeared, as she picked up what was left with one hand and cleaned it with her tongue.
"But I... I wanted it inside me!" Aiko exclaimed, slightly disappointed. "I thought you were going to come inside me." She continued, looking sad and breathless.
Yuji looked at her.
"Sorry...it's just...your tits...drive me crazy..."
He blushed. Aiko looked at him tenderly, then stood up.
"Okay, it's okay. Next time, though, you have to come inside me, okay?" she said, getting up.
She took his arm and pulled him to the bed.
[Yuji's Dorm – Late Night]
The window was open just enough to let in a light draft. The sheet had slipped off her feet and Aiko had one leg entwined with Yuji's. Yuji was lying on his side, his hand in hers. They hadn't spoken in five minutes. But neither of them felt the need to.
Aiko traced invisible circles on his arm with her fingertip, then brushed back a stray strand of his hair.
"Tomorrow... will you wake up with me?"
Yuji laughed softly, burying his face in the pillow and squeezing her fingers. "If you say I can stay here next to you, I'll do it even if Tokyo blows up."
She touched his nose with hers, a smile in her eyes. "And who will save Tokyo, then?"
"Tomorrow I'll only save the moka pot" he murmured, his tone true to his way of making light of things. "You save me."
Aiko shook her head, gently but confidently. "Deal. But a drink of water now doesn't ruin the heroism."
"Already done, boss" he said, showing the bottle at hand. "I'm getting better, huh?"
"Very much." She placed a light kiss on his temple. "I'm proud of you."
Yuji sighed, relaxing his shoulders. He carefully tucked the sheet up to her waist and touched her pulse where her heart beat. "If I set the alarm early, I'll make breakfast. I promise."
Aiko rested her chin on his shoulder, ready as always. "Well done. And no acrobatics before coffee, Itadori."
They both laughed.
"Got it." Another low laugh. "Goodnight, Aiko."
"Goodnight." She closed her eyes, still with one leg entwined with his. The silence wasn't empty: it was filled with shared breaths and small promises.
At a certain point, though, Yuji's breathing changed. A faint tension—imperceptible at first—was working its way under his skin.
Aiko noticed. "Hey… are you okay?"
Yuji barely opened his eyelids. "Yeah… just a bit—"
He didn't finish the sentence.
Because on his shoulder, Sukuna's mouth suddenly gaped open. A low, almost amused growl disturbed the room's calm air.
"So much noise… for such a lively female."
Yuji stiffened. He brought a hand to his shoulder to cover it. Then he realized it could bite his hand, so he pulled it away. Aiko instinctively backed off, without screaming but with wide eyes.
The mouth spoke slowly, deliberately. "You squirm so much… but it seems to me that every time she rides you, you even forget your own name, brat."
Yuji shot to his feet, jaw clenched. His fist trembled. "Shut up."
"And who are you to speak of love?" she asked, in a calm tone that carried the edge of a hidden blade.
Sukuna's mouth curled into something that might have resembled a smile.
"Ah… at last. The little human has a voice. Interesting. You've got thorns, not just perfume."
Yuji punched his own arm. "That's enough."
Sukuna let out a sound like a laugh. "Ah… he's jealous. Cute. You should see her from inside my head, boy. Her voice, when she moans your name… I enjoy it even more than you do."
Yuji clenched his teeth until they grated. The mouth disappeared with a wet hiss, as though sucked back beneath his skin.
SIlence.
Yuji said nothing. He turned toward the window, short of breath.
Aiko had sat up, the covers pulled up to her chest. She hadn't screamed. But her hands were trembling.
After a few seconds, she spoke, softly. "Was that… him?"
Yuji nodded.
"Is he always there? Even when we…?" Her voice cracked.
Yuji turned, slowly. He looked more hurt than angry.
"He can't take control. He can't… do anything. But he can hear. Sometimes. And I… I hate him for that."
Aiko came closer, cautiously. She hugged him from behind, her forehead against his back.
"Then next time we'll ignore him together."
Yuji didn't answer right away. Then, slowly, he laid his hand over hers.
"I'm sorry you have to live with this, too."
She gave a slight shrug. "I chose this, Yuji. I already knew it all and I'm not going back."
***
The first light of day barely filtered through the thin curtains of Yuji's room. His steady breathing marked the rhythm of a deep sleep, his mouth slightly open, his arm stretched out on the now-crumpled sheet.
Aiko was already awake. For a while.
Not out of anxiety, nor out of uneasiness. But out of a simple, poignant thought: the world continued to turn and breakfast had to be prepared at the Tramonto Rosso. She'd left a note—one of her usual hasty but affectionate ones—tucked next to Yuji's cell phone, with his name misspelled and a small smiley face in blue pen.
Then she dressed in silence. She gently stroked his hair, trying not to wake him and closed the door with a gentleness unbecoming of someone facing a long day at work.
Later, when Yuji opened his eyes, it took him a moment to remember where he was. A second more and he turned to the side of the now-cold bed.
He sighed.
Yuji read the note. He smiled. But something in his gaze remained dull.
With half his face still buried in the pillow, he picked up his phone and typed:
Yuji: Have you already run away? You could have at least woken me up for a kiss.
Aiko received the message while placing steaming bowls on a tray. The restaurant was already buzzing, the stoves blazing, the pots sizzling.
She read it without immediately replying. Her expression was hard to read. As if the weight of the previous night hadn't completely lifted.
Then she put the tray down, dried her hands with a cloth and replied:
Aiko: It was the least I could do after putting up with your snoring. But I still owe you that kiss.
Yuji read the reply and laughed quietly to himself in the silence of his room. But his smile was only half-formed. Something stirred in his chest—like an echo. Faint, but there.
He wrote again:
Yuji: Are you still thinking about last night?
Aiko: Aren't you?
Yuji: I think about it too much. But I don't want it to ruin anything. I just want… us. And everything else kept outside.
On the other side of the screen, Aiko paused for a moment. Her hands still damp from the broth, the clatter of dishes around her. Her eyes on her phone and in her chest, a flutter.
Aiko: If he wants to be part of our moments, he'll have to make himself small and quiet. Because the two of us are stronger than him.
Yuji leaned against the wall of the room, his eyes closed. The phone in his hands.
He smiled. But this time, it was a full smile.
In the late afternoon, Yuji arrived at the Tramonto Rosso accompanied by Megumi and Nobara. They had recently finished a grueling workout, and Yuji—hair disheveled, backpack slung over his shoulder and hunger written all over his face—entered the place as if seeking fresh air rather than food.
As soon as he crossed the threshold, the familiar smell of broth and spices twisted his stomach. Aiko was there, at the counter, discussing something with Kazuma, who, as always, was laughing too loudly for the time of day.
"Our hero has arrived" Nobara commented, taking off her jacket. "And look at the way he looks at her!"
Yuji ignored the joke and simply glanced—just one time, but full—at Aiko.
She saw him, raised her chin slightly in an affectionate nod and went back to talking to Kazuma. But that smile, however subtle, was enough for Yuji to feel the muscles in his chest relax a millimeter.
They sat in a corner of the restaurant as the room quickly filled. Amid the chatter and the clinking of glasses, it didn't take long for him to arrive: the customer from the night before. That young man from a few nights ago, dressed too elegantly for a family-run restaurant, his gaze fixed on Aiko as if he were trying to pull off her apron with his eyes.
"There he is" Yuji murmured. His gaze darkened.
When the man approached the counter to order, smiling too much, Aiko greeted him with her usual courtesy. But a glance was enough to understand that he was holding back.
"Here again, huh?" the man said, with a devious half-smile. "I hope my face isn't too unforgettable yet."
Aiko tilted her head slightly. "We get plenty of customers, but every polite smile is earned. May I recommend today's special?"
"Maybe you can also suggest a free evening," he whispered cheekily.
It was then that Aiko, still in her professional tone, replied: "Sorry, I already have a boyfriend and my evening is with him."
The man raised his hands in a dramatic gesture. "Such zeal... I like it. That's fine."
He didn't insist further. But it was enough. It was enough to make Yuji explode inside.
"I'm about to get up," he hissed through his teeth.
Megumi stopped him with a look. "If you hit him, you'll ruin the service. And maybe the floor, too."
"Fuck the floor," Yuji muttered.
Nobara blew on her chopsticks, mockingly. "You're as jealous as a dog in heat."
"No. I'm jealous because she's mine. I hate seeing some assholes look at her like they can afford her."
Kazuma, from the counter, noticed the tension and narrowed his eyes. "Hey, Itadori... breathe, or a teapot will explode."
Yuji didn't laugh. He didn't speak. He glared at him.
But his fists, under the table, were shaking.
At that moment, Aiko approached their table with the order pad. She leaned slightly toward Yuji, her posture relaxed but close.
"Can I take your order... or would you prefer if I gave you a neck massage first?" she whispered, with a sly smile.
Yuji snorted, but his expression softened. "That guy—"
"He's handled and I want to eat with you, not argue" she said, lightly touching his arm.
"I hate him," he confessed softly.
"I know. But now look at me. Not at him."
Yuji stared at her for a moment. Those blue eyes disarmed him every time. Just looking at them made him forget everything else.
Nobara and Megumi pretended to read the menu. Kazuma chuckled in the back of the room.
Yuji nodded, more relaxed. "Then I'll have a caprese... and your kiss afterwards, please."
"Off-menu bonus" Aiko said, walking away.
Yuji followed her with his eyes and at that very moment he felt the skin on his right hand tighten and throb. His heart skipped a beat.
From the scar on his knuckle, a crack suddenly split open—a mouth. His. Sukuna's mouth.
"What a corny little scene" hissed the deep, cutting voice.
"But don't lie, brat. When she laughs like that... it makes you want to take her away...and you know I have a lot to teach you, if you'd just give me some space."
Yuji clenched his fist. "Shut up."
"Ah... look at the way you look at her. If only she knew what's going through your head when she bends over like that, tray in hand..."
Yuji jumped up and walked to the back of the room for a moment.
Nobara followed him with her gaze. "He's not a bad dog... he's growling now."
