First time

The evening sun was bleeding a deep, bruised purple over the rooftops of Tokyo, casting long shadows across the training grounds of Jujutsu High. Yuji Itadori sat on the edge of the wooden porch, his breath hitching slightly as he tried to cool down from a grueling afternoon of sparring with Todo. Usually, the physical exhaustion was a welcome distraction, a way to quiet the restless energy that had been humming under his skin for weeks. Today, however, it wasn't working.

Every time he closed his eyes, he didn't see cursed spirits or divergent fists. He saw Yumi.

He heard the light patter of footsteps behind him, the distinct rhythm he had grown to recognize over the last four months of dating. He didn't have to turn around to know she was there. A soft, floral scent—something like lilies and rain—wafted over him, immediately making his heart hammer against his ribs.

"Yuji? You’re still out here?"

He turned, a grin instinctively spreading across his face despite the ache in his lower belly. Yumi stood in the doorway, looking as small and delicate as ever. She was still in her school uniform, the dark fabric contrasting with her pale skin. As usual, she had customized her skirt to be several inches shorter than the standard regulation, a playful habit that Yuji both loved and cursed. It showed off the smooth curve of her thighs, a sight that had become the primary subject of his late-night frustrations.

"Just catching my breath," Yuji said, his voice a fraction deeper than usual. "You’re done with classes?"

"Mhm." She stepped closer, stepping onto the porch and sitting down beside him. She tucked a strand of hair behind her ear, her large, innocent eyes searching his face. "You look tired. Did Todo go too hard on you again?"

"Nah, I can handle him," Yuji lied, though his body felt like it was vibrating. "I’m just... restless, I guess."

Yumi leaned into him, resting her head on his shoulder. It was a simple gesture, one they had done a thousand times, but today it felt like a match being struck in a room full of gasoline. The warmth of her body through his thin hoodie was agonizing. He put an arm around her, his hand resting on her waist, and he could feel the soft silkiness of her skin where her shirt had hiked up just a fraction.

He had been so careful with her. From the moment they started dating, Yuji had made a silent vow to go at her pace. He knew he was her first boyfriend. He knew she was precious, untainted by the grime of the world they lived in, and he never wanted to make her feel pressured or rushed. But lately, the "nonchalant boyfriend" act was wearing thin.

Masturbation had become a nightly ritual of necessity rather than pleasure, a way to take the edge off so he wouldn't look at her with too much hunger during the day. But it wasn't working anymore. He didn't just want a release; he wanted her. He wanted to feel the weight of her against him without the barrier of denim and polyester. He wanted to know if her skin felt as soft as it looked, and he wanted to hear her voice whisper his name in a way she never had before.

"Yuji?" she whispered, sensing his tension. "Is something wrong?"

"No," he said, perhaps a bit too quickly. He looked down at her, and the sight of her pink lips parted slightly in concern nearly broke his resolve. "Everything’s fine, Yumi. Really."

"You're shaking a little," she noted, reaching out to place a hand on his chest. Her palm was small and warm, resting right over his pounding heart. "Are you getting a fever? Shoko-san said there’s a bug going around the dorms."

He let out a short, breathless laugh. "It’s not a fever. Well, not that kind."

He shouldn't have said it. He saw the flicker of confusion in her eyes, followed by a slow, blooming realization. Yumi might be innocent, but she wasn't dense. She looked down at her hand on his chest, then back up at his face, her cheeks flushing a soft rose color.

"Oh," she breathed.

The silence that followed was heavy, filled only with the distant sound of cicadas. Yuji felt like he was balanced on a wire. He could pull away, make a joke, and go back to his room to suffer in silence. Or he could finally show her a glimpse of what was simmering beneath the surface.

"I don't want to scare you," Yuji said, his voice low and rough. He moved his hand from her waist, his fingers grazing the hem of her miniskirt. "I know we haven't... and I'm okay with waiting. I swear I am. But it's getting harder to be near you and not touch you."

Yumi didn't pull away. If anything, she leaned closer, her breath hitching. "You wouldn't scare me, Yuji. I trust you more than anyone."

"It's not just about trust," he groaned, closing his eyes for a second. "I’m a guy, Yumi. And you’re... you’re everything I want. Sometimes I feel like I'm going to burst just holding your hand."

He felt her hand move from his chest to his cheek, her fingers trembling slightly. She tilted her head back, looking at him with a mixture of nerves and a burgeoning curiosity that made his blood roar.

"I want to know," she whispered. "I want to know what it feels like. With you."

Yuji froze. "Yumi, you don't have to say that just because—"

"I'm not," she interrupted, her voice gaining a tiny bit of strength. "I've been thinking about it too. I just... I didn't know how to tell you. I didn't want you to think I was being bad."

"Bad?" Yuji let out a ragged sigh, his forehead dropping to rest against hers. "There's nothing bad about wanting this. It’s because I love you. That’s why it’s so hard."

He shifted, turning his body toward her on the narrow porch. He reached out, his hand sliding up her thigh, the skin there incredibly smooth and cool against his calloused palm. He felt her shiver, a small gasp escaping her lips, but she didn't move to stop him.

"Can we go inside?" she asked, her voice barely audible.

Yuji didn't need to be told twice. He stood up, taking her hand and leading her toward his dorm room. The walk felt like it took hours, though it was only a few dozen yards. Once inside, he closed the door and leaned back against it, pulling her into the space between his arms.

The room was dim, lit only by the stray light of the hallway under the door. Yuji looked down at her, seeing the way her chest rose and fell rapidly. He felt a wave of protectiveness wash over him, clashing violently with the raw desire he’d been suppressing.

"We can stop whenever you want," he reminded her, his hands coming up to cup her face. "I mean it. Just a word, or a look, and we stop."

"I know," she said, reaching up to grasp his wrists. "I don't want to stop."

He leaned down, capturing her lips in a kiss that was far more intense than their usual chaste pecks. It was deep, hungry, and desperate. Yumi made a small, soft sound in the back of her throat, her hands moving from his wrists to his hair, pulling him closer.

Yuji groaned into the kiss, his hands sliding down her back to her hips. He lifted her easily, her small frame weighing almost nothing, and carried her the short distance to his bed. As he laid her down, the sight of her spread out against his sheets—her skirt hiked up, her hair fanned out—nearly undid him.

He climbed over her, supporting his weight on his elbows so he wouldn't crush her. He kissed her jaw, her neck, the sensitive spot just below her ear. He felt her hands fumbling with the hem of his hoodie, trying to pull it up. He helped her, stripping the garment off and tossing it onto the floor, exposing his muscled torso.

When he pressed back down against her, the feeling of her small breasts against his bare chest made his head swim. He could feel her heart racing against his own, a frantic, shared rhythm.

"Yuji," she whispered, her eyes wide as she looked at his body. She reached out, her fingers tracing the lines of his abs, the scars from his many battles. "You're so... warm."

"You're so beautiful," he countered, his voice thick with emotion.

He reached for the buttons of her blouse, his fingers shaking. He moved slowly, giving her every chance to change her mind. One by one, the buttons gave way, revealing a simple white bra. He felt a pang of tenderness at the sight; she looked so fragile, so innocent, even now.

He moved his hand to her leg again, sliding it under the hem of her skirt. This time, he went higher, his thumb grazing the lace of her panties. Yumi gasped, her back arching slightly off the bed.

"Is that okay?" he asked, his voice strained.

"Yes," she panted, her eyes fluttering shut. "It feels... strange. But good."

Yuji leaned down to kiss her again, his tongue dancing with hers as his hand explored the soft territory of her inner thighs. He was hyper-aware of everything—the way her skin felt like silk, the way she smelled, the way her breath hitched every time he touched a new spot.

He moved his hand higher, cupping her through the thin fabric of her underwear. She was already damp, a discovery that sent a jolt of pure electricity through his spine. He realized then that she had been wanting him just as much as he had been wanting her, even if she didn't have the words for it.

"Yumi," he groaned against her neck. "I’ve wanted to do this for so long."

"Then do it," she whispered, her hands gripping his shoulders. "Please, Yuji. I want to be yours."

He pulled back just enough to look her in the eyes. "You're already mine. This just... this makes it real."

He reached for her skirt, sliding it down her legs and tossing it aside. Then, he moved to his own trousers. The tension in the room was thick enough to touch, a heavy, sweet heat that seemed to vibrate in the air. When they were both finally exposed to one another, Yuji felt a moment of pure, unadulterated awe.

She was perfect. Every curve, every soft line of her body was a masterpiece. He felt a sudden, sharp pang of guilt for the thoughts he’d had, for the way he’d let his lust overshadow the sheer beauty of what they shared. But as Yumi reached out to touch him, her eyes wide with wonder and a bit of fear, the guilt vanished, replaced by a profound sense of intimacy.

He moved back between her legs, his knees nudging them apart. He was as gentle as he could be, mindful of her inexperience, of the fact that this was a threshold she could only cross once.

"It might hurt a little at first," he whispered, stroking her hair away from her forehead. "I'll go slow. I promise."

"I trust you," she repeated, and this time, there was no tremor in her voice.

As he slowly began to merge their bodies, Yuji had to bite his lip to keep from crying out. The sensation was unlike anything he’d ever felt—not just the physical friction, but the overwhelming emotional weight of it. It was the feeling of two souls finally finding the missing piece.

Yumi winced, her fingers digging into his arms, and he stopped instantly. He stayed still, kissing her eyelids, her nose, her cheeks, whispering sweet, nonsensical things until he felt her tension bleed away.

"You okay?"

"Yes," she breathed, a small smile touching her lips. "Don't stop. Please don't stop."

He began to move, a slow, steady rhythm that built like a rising tide. He watched her face, mesmerized by the way her expressions shifted from surprise to pleasure, her eyes glazing over as she lost herself in the sensation.

The nonchalance he had tried so hard to maintain was gone, shattered into a million pieces. There was only this—the heat, the sweat, the sound of their shared breaths, and the feeling of Yumi surrounding him. He felt his control slipping, the pressure in his chest building until he couldn't hold it back anymore.

When the end came, it was explosive, a white-hot flash that left him gasping for air. He collapsed against her, burying his face in the crook of her neck, his body trembling with the aftershocks.

For a long time, neither of them spoke. The only sound was the steady thrum of their hearts slowing down in unison. Yuji eventually shifted, rolling onto his side but keeping her pulled tight against him, her back to his chest. He pulled the covers over them, shielding them from the cooling night air.

He kissed the back of her head, his arms wrapped securely around her waist. He felt a profound sense of peace, a stillness he hadn't felt in months.

"Yuji?" she whispered after a while.

"Yeah?"

"I’m glad it was you."

He tightened his grip, his heart swelling with a love so fierce it almost hurt. "It was only ever going to be me, Yumi. I'm not going anywhere."

As sleep began to pull at them, Yuji realized that the patience he’d practiced hadn't been a burden at all. It had been a preparation. And as he held the woman he loved in the quiet dark of his room, he knew that every second of waiting had been worth it. The fire was still there, but now, it wasn't a roar that threatened to consume him—it was a steady, warm hearth that finally felt like home.
