Summary: When Futaba discovers Ryuji's little secret, her Netorare fantasies come to life as the two betray Joker for each other. Includes: NTR

---

Futaba had never had a sleepover before. It was silly, but she always kind of dreamed of doing it when she was younger. Just a bunch of friends getting together, enjoying each other’s company, and relaxing the night away. 

As she grew up and tragedy after tragedy began to pile onto her life, she lost hope of ever enjoying such simple, trivial things. She didn’t have friends and she didn’t have anyone to care about her beyond Sojiro. 

Then life changed. She went from having no friends to lots, and when the other girls brought up the idea, she had to fight to contain her own excitement. She agreed in an instant, nodding her head and beaming at the idea of enjoying her friends’ company, especially her boyfriend, Akira. 

Ryuji was the first boy to agree, nodding his head and saying that hanging out together would be fun. He even suggested stuff like grabbing some movies and watching it together in a little movie marathon. 

Futaba agreed in an instant. It sounded like great fun, and when Ryuji suggested her boyfriend’s room, really Leblanc’s attic, she was even more excited. Everyone started giving suggestions, offering ideas, and the wheels were rolling as Futaba grinned with excitement. 

Now here they were, all together, having just enjoyed a night of fun and friendship. Futaba laid on her makeshift bed, unable to go to sleep as she quietly thought about the night’s festivities. 

All of the games they played, all the movies they watched… They ate so much junk food, and it had been perfect. Futaba even got the chance to show Haru how to play some games, and teaching Queen how to shoot zombies was awesome. 

Futaba rolled a bit in her bed, looking at Akira as she thought of her boyfriend. She hoped he had a good time, but she wasn’t sure. He seemed weird around her, even rejecting her after she got up the courage to ask if he wanted to share a bed, and around all of their friends!

The orange-haired woman frowned at that, almost glaring at her boyfriend as she wondered how he could turn her down like that. Did she do something wrong? She didn’t think she did. She thought she was just herself, yet Akira was acting weird around her.

She huffed, rolling her eyes, before she rolled herself again. She turned her body, and caught Ryuji standing up in the dark room of the attic. Her eyes widened in confusion as she saw the unmistakable figure of the young man getting up and tip toeing away, out of the large room.

He had to take care not to step on anyone, but he stood made it to the stairs and walked down them. Futaba blinked, confused. Ryuji clearly hadn’t noticed her watching him. The room was dark, after all.

“Hm…” He was probably just leaving to use the bathroom. Futaba shrugged, laying back down as she nuzzled her pillow. She really needed to get to bed, but her mind just wouldn’t agree with her. 

Futaba let her mind wander, thinking of her latest, favorite shows, upcoming movies, and activities she had enjoyed tonight with her friends. It was fun, wonderfully, amazingly fun, but eventually those memories were brushed aside. 

She closed her eyes, trying to sleep once more, only to fail just like she had last time. She sighed, frowning as she looked at the roof of the attic, and quietly coming to a realization.

Where the heck was Ryuji? 

Futaba lifted up her head and looked around the attic, finding the blonde was still missing from the room. She considered just brushing it aside, but she just couldn’t sleep. Maybe stepping out would have been good for her? Something to do, something that would satiate her curiosity, so maybe she would be able to fall asleep. 

She stood up and walked over and around her friends, taking care not to accidentally step on Inari or the snoring Ann, before she reached the stairs. She carefully walked down them, moving on the tips of her feet and she saw the bathroom door was open, and light was seeping out. 

Futaba approached it, moving closer. Her brow furrowed as she slowly adjusted to the light, opening her mouth to ask if Ryuji was okay, only to fall asleep as her eyes widened and she saw something that stunned her. 

Ryuji, sitting on the lid of the toilet, with his cock out. His dick was hard, throbbing as it was aimed to the roof, standing like a tower of flesh. Futaba’s jaw hung low as she looked at the stick, gasping as her eyes slowly traveled up and down the member. 

He was big. He was so fucking big.

Futaba had seen a lot of cocks before. She spent a lot of her time on the internet, of course. She had even seen her boyfriend’s penis once, just once. Akira’s dick was about as big as one would expect for a young man, an average sized thing that Futaba had taken as an important lesson.

Real life cocks just weren’t as big as the fictional, hentai ones. Those things were unrealistic monsters. 

Yet here she was, looking like she had just seen a Pegasus for the first time in her life. That was how she looked at Ryuji’s dick. It stole her breath away, and it made her heart race as her mind thought of her darkest fantasies, and her most twisted desires. 

Futaba had always had a thing for Netorare. The idea of cheating on one’s loved one, being corrupted by a third party, and embracing the feeling. That dark, evil sensation always sent chills up her spine and sparks down to her pussy.

She could feel her panties becoming wet as Ryuji’s dick throbbed in his hands, and he groaned. His hand moved faster, and Futaba’s legs squeezed together as she tried not to imagine it pushing into her. 

She failed, of course. 

Was Ryuji really going to cum with that monster? Shoot a thick, huge load of cum chowder into the toilet? T-that seemed like such a waste! Wouldn’t it be better in some gorgeous, hot woman?

Wouldn’t it be better if someone were to help him… take care of that thing? Futaba licked her lips as her heart raced, and she considered giving him a better place to put it. Some small voice in Futaba’s head told her not to, to back away, to go back upstairs and pretend she didn’t see anything. 

Futaba didn’t listen as she moved closer, and greeted the blonde. “Hey, Ryuji,” she cooed, shocking the man.

“F-Futaba!” Ryuji almost screamed as he scrambled to hide his cock under his boxers, but all that did was make a big tent out of them. He blushed as she moved closer, wearing only a big, black shirt that stretched down her body and some short, shorts. 

“Hey.” She took a moment, turning her head to look at the stairs. She listened for any of the other Phantom Thieves waking up, before she looked at the young man. “Need some help?”

“I-I-” He was like a deer in headlights, and so Futaba decided to give the young man a hand with his words.

“I think the words you’re looking for are, ‘I’d like that, Futaba.’” This sexually forward, blunt part of her was new. It sent her heart racing as her face burned hot, and she licked her lips. She felt like she was out on a hunt, and ready and raring to go. 

The little voice that tried to hold her back was long gone now as Futaba began to live out her darkest fantasies, imagining herself as the sweet, innocent girlfriend of the faceless protagonist. She was all alone, with a big-dicked pervert, too weak to resist the aroma and musk of his veiny dick.

“Don’t hide your cock on my account, Ryuji. I was watching you touch yourself just a few minutes ago. I never knew you had such a big… club in your pants,” she giggled, almost drunk on the scent alone. 

“W-what?” Ryuji almost jumped in his seat as he watched Futaba fall down to her knees, using a bath mat to help make herself comfortable as she came face to crotch with Ryuji’s python. She smiled at it, looking it over as he tried to make sense of this all. 

He opened his mouth, and he lifted up his hands to push the small girl away, only to gasp and shudder as her finger stroked the side of his dick, caressing it slowly. 

“Can I ask you who you were jacking it to? Probably Ann, right?” she thought aloud, pouting at the thought. Her finger traveled up and down the erection, gently stroking it as she thought of the buxom blond, and how Ryuji would hold her hair like handlebars as he fucked her face.

She could wear her hair like that… “Maybe Makoto?” she thought, imagining the strong, powerful woman reduced to a moaning slut on the man’s dick. She trembled, swallowing down spit as she shuddered.

Her warm breath touched the dick, making Ryuji moan as Futaba looked into his eyes. “Haru?” The big-titted woman was wealthy, kind, and gorgeous. The perfect woman, with tits as big as Futaba’s head. The thought of her own Ryuji made her pout as she leaned forward to peck the tip with her lips. 

Futaba didn’t ever consider the reality of the situation. She didn’t know what Ryuji was thinking, who he was thinking of that made his cock this hard. He stuttered out an answer as her hand stroked his cock up and down. 

“Um… Y-you, Futaba.”

“...Huh?” She blinked, eyes widening. 

“I-I was thinking about you.” Knowingly or not, Ryuji stoked the flames of Netorare inside of Futaba. His words were the start of her fantasies, her darkest and most terrible ones, but also the ones she had always been curious about.

As for Ryuji, even though Futaba was his best friend’s girl… he wanted her. Ryuji was jealous of his best friend, for many reasons. Strong, fast, smart, charismatic… The damn bastard seemed to have everything, while Ryuji lived as the butt of a joke. 

All the girls fawned over him, none more than Ryuji, so the idea of Futaba’s body just made his cock go crazy, and it certainly didn’t hurt that Futaba was pretty hot. Slender figure, beautiful face, long, flowing hair, and a curvy, bouncy ass…

Yeah, she was perfect. 

Futaba’s mouth hung open, before it closed and she grinned, panting as her heart raced. “T-this is just like my favorite doujin. T-the man with the harem loses his girls, one by one, to his lamer, less cool friend. They betray him, all devoted to the big, hard, throbbing cock that stole their hearts away!” 

“...Am I the lamer friend?” Ryuji asked, raising his brow. “L-look, Futaba, j-just let go of my dick and-”

“No!” Futaba squeaked, gripping the base of his dick. He grunted, shaking as her soft, warm hand held him tight. “I-I want this. If you were thinking about me, I-I can bring your fantasies to life.” Futaba pressed the warm cock against her cheek, smiling at him. “Don’t you want to fuck Akira’s girlfriend? Prove how better your are? Come on, it’ll be our little secret,” she promised, winking at him. 

Ryuji opened his mouth, but nothing came out. His cock was throbbing. He had never felt this hot before. Futaba was practically begging for his cock… He bet she never did that with Joker.

“Deal.” He couldn’t stop himself. He wanted this. She wanted this… Fuck what Akire wanted.

Ryuji placed his hand on Futaba’s head, and she took his cock into her mouth, bobbing her head up and down, moaning as it filled her mouth. It pressed against her cheek as her tongue slid along the underside of the shaft, tasting it, moving up and down on it.

“H-holy crap! You’re amazing!” he gasped, stroking her orange-hair as Futaba beamed with pride. Not an easy thing to do with a cock in your mouth, but she accomplished it nonetheless.

Futaba slobbed all over his prick, moving up and down, smacking her tongue around all sides of it, slurping on it as the sound of their fun filled the bathroom. Ryuji leaned forward, slamming the door shut, before he let Futaba return to her duty, bobbing her head up and down as her nose pressed into his crotch.

“Fuck, you’re so good… Akira doesn’t deserve a babe like you. Ah, keep it up, slut.”

Oh, dirty talk… Futaba liked that. She loved that!

Futaba kept her lips sealed around Ryuji’s shaft, moving up and down, breathing through her nose as she marveled at the taste and girth of the cock. The one thing she saw Akira’s dick was when their kissing was getting a bit too passionate. 

It was barely half the size of Ryuji’s monster. She imagined that thing stealing her away, taking her from her boyfriend, corrupting her innocent mind as she realized just who her real Key Item was… Ryuji certainly had the bigger ‘key.’

Ryuji’s balls quivered, and her eyes widened as she felt her throat being filled. Cum flooded down her mouth, and down her throat. It flowed down into her stomach as her eyes widened and she trembled from it all. 

Ryuji was the one to pull out. Futaba was too dumbfounded as the cum filled her tummy. She was even more shocked as Ryuji’s dick popped out of her mouth and shot more semen onto her face, plastering her and her glasses with his cum.

She gasped, feeling the semen coating her face as Ryuji moaned. That was probably one of the best orgasms of his life…

He looked down at her, and he wanted to apologize, but there was something about Futaba that just… silenced him. She took off her glasses, and he stared at her beautiful face, cum trickling down her cheeks. Some of his load even got in her hair, and was slowly going dripping to the ground. 

Futaba stared into his eyes as she licked her lips, catching some of his semen into her mouth. She smiled at him, giving him a half-lidded smile as he smirked. Both of them had the same idea. No way was this going to be enough.

In their hungry, almost drunken state, the two decided to go even further. They didn’t care about what was right or what it took. They wanted to feel good. Futaba placed her glasses on the sink and stood up with Ryuji. 

She bent forward, over the toilet, and wiggled her ass side to side as she smiled at Ryuji. She pulled her shorts down for him, before giving her ass a spank. 

“Fuck me,” she begged. “Fuck me like Akira never could.”

Ryuji did so, with an eager grin on his face. He pushed his cock into Futaba’s pussy, pushing her apart as she let out a loud, guttural moan. She was shaking with a smile on her face as he began to back his hips up, before pushing in again.

His pace quickened as Futaba moaned, and she began to recreate dialogue from some of her favorite Netorare-filled doujin. 

“Ah! Fuck, you’re so much bigger than my boyfriend! You’re fucking me like he never could! Your cock is so big!”

Ryuji grinned, and he slapped Futaba’s ass, before he asked, “Tell me his dick is small.”

“It’s so small! Ah! Akira’s dick is so tiny, Master!” 

Ryuji loved hearing that. Mr. Perfect wasn’t so perfect after all. Ryuji fucked Futaba faster, leaning forward so that he could grope and play with her small breasts. 

“Akira ever fuck you?”

“N-no!”

“Good. Keep it that way. Your pussy is mine.” He slammed into her, balls slapping against her. “Your ass is mine. Your mouth is mine.”

“My heart is yours,” she panted. “My mind is yours. I’m all yours… Master.” 

Ryuji grinned, and he gave Futaba another spank as he grinned. “Fuck yeah! Tell me you’d break up if Akira if I told you to.”

The lack of hesitation shocked not only Ryuji, but Futaba, but she couldn’t help it. Her heart was swelling for Ryuji, not Akira. Ryuji was everything she wanted in a lover, the man of her dreams. Her twisted, slutty, naughty dreams.

“I’d dump his ass in a second if you wanted, Master. You’re amazing! You’re stronger than him, tougher than him, and ahh! A better lover than him!” 

Ryuji couldn’t contain himself any longer. He loved what he was hearing, loved hearing how he was better than his best friend. And from his bro’s girl too! He dug his hands into Futaba’s hips, feeling her pussy squeeze down on his shaft.

His cock pressed against her g-spot, and she shuddered, moaning as her brain melted between her ears. Her pussy squeezed tightly down on Ryuji’s shaft as she moaned, feeling her own orgasm coming closer and closer. 

Every thrust sent her closer to the edge, and her pussy wrapped tighter around his shaft as drool spilled down from Futaba’s lip. 

They came together, crying out so that all they could hear was each other, and all they felt was one another. 

Ryuji’s semen filled Futaba’s pussy, coating the walls as he panted and trembled. His hands stroked her body, feeling her soft flesh, before he pulled on her. 

Futaba spun on his cock, carried by his strong arms as she smiled at him. The two kissed, lips pressed together as they let out tiny, content moans with one another. Ryuji’s dick was still in her as she wrapped her arms around him, held over the air in his arms as they kissed.

The next day, the group made breakfast together. They were all cooking, with Haru leading the group as Akira walked over to Futaba. 

“Hey, babe,” he smiled, leaning in to kiss her. Futaba stared at him, and was thankful his eyes were closed. He would have seen her brow furrow if they were. She pulled away, dodging his kiss.

He pulled away, brow raised up as she put on a smile. “Sorry, uh… Just haven’t brushed me teeth.” 

“Oh.” He nodded his head, as Ryuji walked down the stairs. Futaba smiled as soon as she saw him running to him to hug him. 

“Hey! Ryuji, do you want to hang out later? I wanted to go shopping for some new games!” She smiled, pressing her tits against the man’s chest as she fluttered her eyes. 

Ryuji grinned, nodding his head. “Sure. Sounds fun.” He glanced at his best friend, seeing the mild sting in his silver eyes. Ryuji knew he was ruining his relationship with the man, but what he was getting out of it was… well, totally worth it.

Futaba smiled, releasing Ryuji from the hug and standing beside him. His hand slithered down her body, giving her ass a squeeze as she smiled at her boyfriend, feeling her heart race as she lived her fantasies with Ryuji.
