Naruto's Lustful Quirk

In the busy halls of U.A. academy, Naruto Uzumaki drew attention without trying. Students from every class knew his name and smiled when he passed. His blond hair caught the light from the windows, and his blue eyes held a steady warmth that made people feel noticed. He talked easily with support course kids who kept to themselves and with the loud competitors in Class 1-A and 1-B. His quirk, Evolution, let him sense what someone could become and give it a push, sometimes making their power grow in new ways. It worked on him too, sharpening his body and mind when he focused.

A few days earlier, out in the woods past the city edge, he had tried to boost the parts of his brain that handled quick thinking. He wanted an edge in fights. Instead, he hit the wrong spot and sent a rush straight through the pathways tied to want and heat. The effect hit hard and stayed. Every glance at someone he liked turned sharper. His pulse jumped faster around certain girls. He kept it hidden by training harder than usual, but the edge never fully left.

Setsuna Tokage had watched him for weeks. She liked the way he treated people, the way he noticed small things about her quirk and never made her feel like just another classmate. Her own power let her split pieces off and pull them back together, and she used it to tease during joint drills, floating an eye over to wink at him or sending a hand to ruffle his hair. Today she decided to find him after classes. Training Gym Gamma stayed quiet once the sun dropped, and she wanted a real conversation without the whole school watching.

She pushed the door open and stepped inside. The place smelled like old sweat and clean mats. Naruto was already there, shirtless, doing push-ups that lifted his whole body off the floor. A faint golden glow flickered around his arms and back each time he rose. Sweat ran down the lines of his chest and stomach. His muscles moved in steady rhythm, broad shoulders flexing, the cut of his abs tightening with every rep.

Setsuna let one hand detach and wave from across the room before it flew back to her wrist. "Naruto-kun," she called, voice light and teasing as she walked closer. "Didn’t expect to find you hiding in here. Trying to get even stronger, or just hoping someone cute would walk in?"

He finished the set and stood up in one smooth motion. His chest rose and fell, skin shiny under the lights. When he turned, the usual easy smile was there, but something hotter sat behind it. His eyes moved over her face and stayed a second longer than usual.

"Setsuna. Hey. Yeah, just burning off some energy. Saw you in the drill earlier. That split move you pulled was smart. You made it look easy."

She felt the compliment land warm in her stomach. She stepped in closer, hips swaying a little on purpose. One of her eyes floated out, circled him once, then popped back into place. "You noticed, huh? I was hoping you would. Everyone says you see what people can really do." She reached out and let her fingers brush his forearm. His skin felt hot. "So, what do you see when you look at me? Just the lizard girl with party tricks, or something else?"

His pulse kicked harder at the touch. The heat in his head surged without warning. He laughed once, low, and shifted half a step nearer so her hand stayed on him. "Something else. Your quirk is more than tricks. It’s quick thinking and guts. And you… you keep things fun. I like that." His voice dropped without him meaning it too. He reached up and rested his palm on her elbow, thumb moving in a slow circle. "What are you doing here so late? Looking for a workout, or something else?"

Setsuna’s breath caught. The way he looked at her now felt different, heavier. She had planned to flirt and maybe steal a kiss, then laugh it off. Instead, her body leaned in on its own. "Maybe both," she said, softer than she meant. Her detached eye floated again, watching the way his throat moved when he swallowed. "I’ve had a crush on you for a while. All those times you helped people get stronger… I wondered what it would feel like if you paid that kind of attention to me. Want to show me?"

The words hit the already frayed edge inside him. He closed the space between them, hands sliding to her waist and pulling her flush against his body. "Setsuna," he said, voice rough, "you have no idea how long I’ve been noticing you. The way you move. The look in your eyes when you’re trying something new. It’s been driving me crazy." His mouth hovered near her ear. "If you want my attention, you’ve got it."

She made a small surprised sound, then melted into him. Her arms went around his neck. "Whoa, you’re not holding back today." She tilted her head and brushed her lips along his jaw. "I like it. Show me more. What would you do if I told you I want you to fuck me until I can’t think straight?"

That broke the last bit of control he had left. A low sound rumbled in his chest. He caught her mouth in a hard kiss, one hand sliding up into her green hair, the other gripping her hip and pressing her tight to the hard line of his cock through his shorts. She kissed back just as fierce, her tongue meeting his. Her quirk kicked in without thought. Both hands came off at the wrists and slid under his shirt, palms flat on the hot skin of his back while her main body stayed locked to him.

He walked her backward until her shoulders hit the wall. The kiss turned messy, wet sounds filling the quiet gym. He broke it only to mouth down her neck, teeth scraping lightly. "You taste good," he muttered against her skin. His fingers found the zipper of her gym uniform and dragged it down slow. He paused, eyes dark, checking her face.

She nodded fast, cheeks flushed. "Don’t stop. I want this." Her detached hands helped shove the top off her shoulders. The sports bra underneath hugged her breasts, nipples already tight against the fabric.

He lifted her like she weighed nothing and carried her to the nearest mat. He laid her down and followed, mouth on her chest, sucking one nipple through the bra until she arched. Then he unhooked it and tossed it aside. His tongue circled the bare peak, sucking harder while his hand kneaded the other breast. Setsuna moaned, fingers in his hair. One of her detached hands slipped into his shorts and wrapped around his cock, stroking slow and firm, thumb rubbing over the head.

Naruto groaned into her skin. He kissed lower, across her stomach, then hooked his fingers in her shorts and panties and pulled them down in one motion. He settled between her thighs and licked into her without hesitation, tongue dragging through her folds before focusing on her clit. He sucked and flicked, reading every twitch of her hips, every sharp breath. She tasted sharp and sweet. Her legs shook. A detached hand guided his head while another stroked herself right beside his mouth.

"Fuck, Naruto," she gasped. "Right there. Don’t stop."

He kept going until she came, back bowing off the mat, a broken cry leaving her throat. Her quirk pieces fluttered before snapping back together. He didn’t give her time to settle. He shoved his shorts down, lined up, and pushed inside in one long thrust. She was tight and hot and still pulsing from the orgasm. He started moving, deep and steady, one hand pinning her wrists above her head.

"Harder," she breathed. "Come on, fuck me like you mean it."

He did. His hips snapped faster, the golden glow of his quirk flickering along his arms as he poured more strength into every thrust. The mat slid a little under them. Skin slapped. She wrapped her legs around his waist and met him halfway. One of her hands came loose again and reached down to rub her own clit while he fucked her.

"You feel perfect," he growled against her mouth. "So fucking good around me."

She clenched hard when she came again. He followed right after, pushing deep and staying there while he spilled inside her, pulse after pulse. The boosted load was heavy. It leaked out around his cock when he finally pulled back a little.

They didn’t stop. He rolled them so she was on top. She rode him slow at first, then faster, hands braced on his chest. He sat up and sucked on her tits while she moved. She used her quirk to detach a hand and reach behind herself, fingers teasing his balls while she bounced. He came again, and she followed, shaking on top of him.

Later they lay tangled on the mat, breathing hard. Sweat cooled on their skin. Setsuna traced lazy circles on his chest with one finger. "That was… yeah. We’re doing that again."

He kissed her forehead. "Whenever you want."

They dozed. The gym stayed quiet around them. When the first gray light of morning came through the high windows, they were still wrapped together. Setsuna’s hair spread across his shoulder. His arm stayed around her waist.

The door opened with a soft creak. Itsuka Kendo stepped inside, orange hair pulled back, wearing a simple training shirt and shorts. She had come for early space to practice her Big Fist quirk without breaking anything. She froze two steps in.

Naruto and Setsuna were naked on the mat, bodies pressed close. The smell of sex hung in the air. Itsuka’s face went red. Her eyes flicked over Naruto’s chest, the way his cock rested against Setsuna’s thigh, still half-hard and shiny. Her own thighs pressed together before she could stop them. One of her hands enlarged a little from the shock, then shrank back.

"I… didn’t mean to walk in on this," she managed. "I’ll just go."

Setsuna lifted her head, sleepy and smiling. One eye floated over, took in Itsuka’s flushed face and the way she shifted on her feet, then floated back. "Itsuka, wait. Don’t leave." She sat up, the movement making her breasts shift. Cum still glistened on her inner thighs. "You’ve had a thing for him too. We’ve talked about it. Why not stay? He’s… really good. Fucked me all night. You should feel what that’s like."

Naruto opened his eyes. The sight of Itsuka standing there, strong and clearly turned on, sent another wave of heat through him. His cock twitched and started to fill again. He sat up slowly, not hiding anything. "Itsuka. If this is too much, say so. But Setsuna’s right. We’re all friends. And after last night…" He gave her the same warm smile she had seen in class a hundred times, only now it carried something rawer. "I’d like to make you feel good too. You’re always looking out for everyone. Let me take care of you."

Itsuka stayed by the door. Her heart hammered. She had thought about this exact thing more than once, late at night, hand between her legs. Seeing Setsuna satisfied and leaking, seeing Naruto’s body and the open want in his eyes, made her decision easy. She closed the door. Her fingers shook a little as she pulled her shirt off. The sports bra underneath strained over her full breasts.

"I’ve thought about it," she admitted, voice low. "A lot. You pinning me down. Fucking me until I can’t stand." She walked closer, one hand enlarging on purpose this time. She rested the big palm gently on Naruto’s shoulder. The warmth of him went straight through her. "If you both really want this…"

Setsuna grinned and sent a detached hand to tug Itsuka down between them. The floating fingers slid up Itsuka’s thigh and under the hem of her shorts, brushing over damp panties. "We want it. Let me show you how wet you’re already getting."

Itsuka let herself be pulled in. Setsuna leaned forward and kissed her, slow at first, then deeper. Tongues slid together. Wet sounds filled the space between them. One of Setsuna’s detached tongues floated in and licked along Itsuka’s jaw while the main kiss kept going. Itsuka made a surprised, turned-on noise and kissed back harder.

Naruto watched, stroking himself once, slow. He reached out and ran a hand down Itsuka’s back, then lower, squeezing one firm ass cheek. "That’s it," he murmured. "Just feel it."

When the kiss broke, Itsuka turned to him. Her eyes were dark. "Show me," she whispered. "Fuck me like you fucked her."

He kissed her, one hand cupping her cheek, the other sliding around her waist to pull her close so she could feel his cock against her stomach. She moaned into his mouth and wrapped her enlarged hands around his torso, fingers tracing muscle. One big palm dropped lower and closed around his shaft, stroking him with careful pressure.

"God, you’re thick," she breathed.

Setsuna moved behind her, mouth on Itsuka’s neck, sucking marks into the skin. A detached hand slipped under Itsuka’s bra and pinched a nipple. Naruto helped strip the rest of her clothes off. Itsuka’s body was strong and curved in all the right places, breasts heavy, nipples dark and tight, pussy smooth and already dripping.

He laid her back on the mat. Setsuna straddled Itsuka’s face without being asked, lowering her cum-slick pussy onto her friend’s mouth. Itsuka licked without hesitation, tongue pushing into Setsuna’s folds, tasting both of them. Setsuna moaned and rocked her hips.

Naruto settled between Itsuka’s spread thighs. He rubbed the head of his cock along her slit, then pushed in slow, watching her face the whole time. She was tight, walls gripping him as he sank deeper. "Fuck, you feel good," he said, voice rough. He started thrusting, steady and deep, grinding against her clit on every push.

Setsuna rode Itsuka’s face, one detached hand reaching back to stroke Naruto’s chest, another floating down to rub Itsuka’s clit while he fucked her. "She’s so wet for you," Setsuna panted. "Look at how she’s taking that cock."

Itsuka moaned loud against Setsuna’s pussy. Her enlarged hands gripped Naruto’s hips, pulling him harder into her. He leaned down and sucked one of her nipples into his mouth, teeth grazing. She came first, walls fluttering and squeezing, a gush of wetness around his cock. The vibration of her moan pushed Setsuna over the edge too. She ground down, flooding Itsuka’s mouth.

Naruto kept going until he followed, burying himself deep and pumping her full. The load was heavy again. It leaked out when he pulled back.

They shifted positions. Itsuka used her enlarged hands to lift Naruto and settle him on his back, then climbed on in reverse, facing his feet. Her big palms cupped his ass and held him steady while she sank down onto his cock. She bounced, breasts swaying, the wet sound of her pussy sliding on him filling the gym. One massive finger teased his rim while she rode. He groaned and thrust up to meet her.

Setsuna moved in front of Itsuka, kissing her deep while Naruto fucked her from below. Then she turned and presented herself. Naruto sat up enough to grab Setsuna’s hips and pull her back onto his cock while Itsuka stayed on his face, grinding her pussy against his tongue. Setsuna reached back with a detached hand and stroked Itsuka’s clit.

They moved together like that for a long time, switching who was where, hands and detached parts everywhere. Naruto lifted them easily when he wanted a new angle. His quirk glow flared brighter during the hardest thrusts, giving him endless stamina. The girls used their quirks to touch more places at once, heightening everything.

Itsuka came again while riding him, head thrown back, orange hair sticking to her sweaty neck. Setsuna came with her face between Itsuka’s thighs while Naruto took her from behind. He filled both of them more than once, thick loads dripping down their legs and onto the mat.

By the time the sun was properly up, they were all wrecked. Sweat-slick skin, bite marks, cum leaking from swollen pussies. They lay in a loose pile on the biggest mat, breathing slow. Setsuna’s head rested on Naruto’s chest. Itsuka curled against his side, one enlarged hand resting possessively on his stomach.

Setsuna laughed softly, tired and happy. "We should do this again. Soon."

Itsuka made a quiet agreeing sound and nuzzled closer. Naruto’s arm tightened around both of them. The gym was quiet except for their breathing. Outside, U.A. was waking up, but in here the three of them stayed tangled together, bodies still humming from everything they had shared.
