Konomi- no, Kouji took a deep breath as he walked to the park. Since middle school, when he and his brother had reuinited, done a lot of self-reflection and had discovered he was a trans guy. School had finished, and he and Kouichi were planning and moving to Osaka for college with their schoolfriend Takuya. This was a good chance to tell Kouichi - he could focus on Takuya later.

Still living apart for the moment, the park was a good half-way point between his house and Kouichi's, so they frequently met there during the school year.

Sure enough, as Kouji neared the playground as the sun set, Kouichi was already there. The playground was empty, as always, so Kouichi was leaning against the swing set.

Kouichi looked up with a grin. "Hey, Konomi." Kouji did his best not to wince. "You wanted to meet up?"

Kouji nodded. "Yeah, uh, there's something I wanted to tell you. I…" He sank down onto the swing seat, staring at his feet.

Kouichi hummed, waiting. After a minute, he took out a vape pen and offered it to Kouji. "Want some?"

"Weed?" Kouji asked. When Kouichi nodded, he took a long pull. He didn't usually smoke, though Kouichi did to deal with his anxiety. They both used it to relax in the summer, and sometimes he would lend it to Kouji to deal with panic attacks. "I wanted to say… um…" He took a breath and took one more hit. "I'm a trans guy, not a girl."

Kouichi blinked and his expression softened. "Aw, Konomi," he said, "it's okay to think about that."

Kouji winced. "My name is Kouji, now," he said.

"No," Kouichi said. Suddenly, he had pulled rope out of his ass apparently, because Kouji had no idea where he could have hidden it, but Kouji's arms were quickly tied to the swing chains. "You're my pretty little sister, Konomi."

Kouji pulled at the ropes, but there was no give. "What are you doing?"

Kouichi smiled and cupped Kouji's cheek. "Just getting you ready from some fun, sis." Kouji whimpered as Kouichi began to touch his chest. He struggled harder, but to no avail. "You're so pretty, Konomi," Kouichi murmured. "I've always wanted to play with your body. You're such a good little girl."

"No," Kouji protested, his heart racing as Kouichi twisted his nipples through his shirt. His breath hitched as Kouichi's hand moved to his crotch.

"What's wrong, Konomi?" Kouichi asked, pressing against his clit. "Don't worry, I'll make it feel good for you too."

Kouji shut his eyes tightly. "I'm a boy," he whispered.

"You may say that, Konomi, but I know what you really are," Kouichi teased, rubbing his clothed pussy faster. "You'll always be my pretty little sister, no matter what you say or do." An involuntary moan escaped Kouji as he tried to escape again.

Kouichi used the chance to rip down Kouji's pants and boxers, exposing his wet pussy. "That's a good girl, Konomi. You're so wet for me already."

Kouji's eyes widened as Kouichi began to rub his clit. His body shook despite himself and he moaned in pleasure.

"You're enjoying this, aren't you?" Kouichi leaned in and sucked a dark bruise onto Kouji's neck that only made his clit throb harder.

Kouji whimpered as Kouichi forced the vape back into his mouth and he choked as he breathed in, smoke filling his lungs. He sputtered, shaking his head as it began to swim from the hazy fog of the drug.

"Good girl," Kouichi praised. "You were always so obedient."

Kouji tried to shake his head, but he felt his body relax without his permission as Kouichi's hands explored his body. Kouji's vision blurred as Kouichi pressed it back into his mouth.

"You're such a beautiful girl," Kouichi murmured as Kouji breathed in more weed. "I've always wanted to be close to you like this." Kouji's heart raced despite the drug as Kouichi kissed his neck, nipping and dragging his tongue along the sensitive skin.

Kouji bit his lip against the surge of pleasure coursing through him. "Please, stop, nii-san…"

He looked up as two people neared the playground, breath hitching, but Kouichi just forced the vape back to Kouji's lips. "Again. Let's make sure you're nice and obedient for our guests."

Kouji trembled in Kouichi's grips, arms hanging limp from where the rope bound his wrists, his legs spread wide and thighs shining with slick. The smoke filled his lungs and clouded his thoughts, distorting everything around him. He could feel eyes on him, like hot coal searing his skin. "Please," he slurred, already fucked up from the weed.

Kouichi just grinned, fingers massaging Kouji's breasts. "Aw, don't worry, Konomi." Kouichi's voice dripped with mock sympathy. "I'm not going to hurt you too much. Just enjoy the ride."

Kouichi slipped two fingers into Kouji, pumping them into him. Kouji heard himself moan, like it was someone else, unable to control the sounds escaping him.

Kouichi's hot breath was on his neck as he tore open Kouji's buttoned shirt, buttons flying everywhere. "Besides, no boys have tits this big."

"They are big," Kouji slurred, too high to argue as Kouichi groped his bare tits. "Mm, feels- feels good- no-"

Kouichi chuckled, "That's right Konomi." He pinched Kouji's nipples and he gasped with pleasure. "You're just a little whore, getting off on being touched by your big brother."

"No," Kouji groaned, but his body was betraying him.

"You're such a little liar, Konomi," Kouichi murmured. He dragged his tongue along Kouji's ear. "But that's okay. I like a little resistance."

"Hey, what are you doing?"

Kouji's head shot up and hope flared in his chest, but Kouichi just forced the vape back into his mouth.

"Sorry, sir," Kouichi called as Kouji sobbed and smoked more. "My little sister just thinks she's a boy, so I'm teaching her a lesson." He twisted Kouji's nipples hard. "Go on, Konomi. Tell them."

Kouji coughed hard. "My big brother is fucking me straight," he choked out, eyes watering. He didn't mean for it to sound wanton, but it did. It definitely did.

Kouichi smiled. "That's it. Louder, so everyone can hear you. Let them know what a dirty little whore you are." He raised his hand and spanked Kouji's pussy, hard.

Kouji shouted in pleasure, his voice carrying across the playground. "My big brother is fucking me straight!"

"Oh good." The stranger's hand tightened on his daughter's shoulder. "You should watch, Zoe. This is what will happen to you if you turn gay."

Kouji could only watch as Kouichi began to finger him again. "Please stop." His voice trembled. "This isn't right."

The man just laughed. "You're not in any place to make demands, you faggot." He forced his daughter to her knees beside Kouji and Zoe watched eagerly.

"Zoe needs to learn her place." Kouichi gripped Kouji's face. "And you, Konomi, are the perfect toy to drive the lesson home." He pulled his fingers out of Kouji's pussy and shoved them into his mouth. Kouji moaned and sucked his fingers clean until Kouichi rounded him and pulled out his cock. He teased Kouji's clit with it. "See? I told you that your dyke cunt would get wet. Just like a stupid little girl."

"Please," Kouji protested, "this won't make me a girl!"

"We'll see," Kouichi said before easing into Kouji. "You're a boy, are you?" Kouji nodded. "That's so funny, because…" He wrapped his hand around Kouji's throat, just tight enough that the threat was there. "You're enjoying this like a girl."

"Can I touch her?" Zoe piped up. She whimpered as her father backhanded her.

"No lesbianism," he warned.

Zoe nodded and crawled closer, her fingers reaching out to touch Kouji's body. He wanted to shove her away, but he couldn't even struggle against the ropes anymore, let alone break free.

Instead, he moaned helplessly as Zoe sucked his sensitive nipples. Her tongue swirled around them and he sobbed as she bit them, the mix of pleasure and pain making him arch.

"You'll have milk soon too," Kouichi growled in his ear, "once I breed you." He emphasised the statement with a hard thrust that made Kouji see stars.

Kouji shuddered from a mix of fear and pleasure at the idea of being bred.

"You're so easy, Konomi," Kouichi taunted as he set up an easy pace, enjoying Kouji's shaky moans as Zoe sucked his nipples. "A little bit of attention and you melt. And you take my cock so well, like you were born for it." Kouichi leaned in. "Maybe you were. I was born first. Maybe you were made with this tight, wet pussy just to take your big brother's cock."

"Nii-san," Kouji groaned. He arched into Zoe's mouth until her father pulled her away by her hair.

"That's enough. Konomi isn't being rewarded, and you're not a lesbian."

"Sorry, daddy." Zoe settled on her knees, watching the two brothers.

Kouji moaned, eagerly meeting Kouichi's thrusts. Kouichi forced him to smoke more, more, more, until Kouji could barely do anything but babble.

"You're nothing but a sissy little dyke," Kouichi groaned, "and it's my job as your big brother to fuck you straight."

Kouji sobbed in pleasure and humped Kouichi's cock. "Yes!" He was too fucked up to even disagree. "Fuck me straight, nii-san!"

Kouichi grinned as his brother gave in to his commands, reduced to nothing but a whimpering, submissive slut. Zoe couldn't help but touch herself to the sight.

"You like that?" Her father growled. "You like seeing a stupid lesbian put in her place?"

"Yes, daddy," Zoe whispered, desperately rubbing her clit. "I love seeing Kouichi fuck his tranny sister back to normal." Her father hummed, having more self control, but planning fun nights in the future when his wife was away.

"You hear that?" Kouichi grabbed Kouji's hair. "I'm fucking your tranny cunt normal again."

"Thank you," Kouji groaned. "Thank you, nii-san!"

"What's your name?" Kouichi bit his neck hard.

"Minamoto Konomi!" Kouji groaned, tilting his head back. "Nii-san fucked me back to a girl again!"

"Good." Kouichi finally, finally, sped up and began to slam into Kouji's virgin pussy. Zoe moaned, desperately humping her own hand until she came in her panties.

Without pulling out, Kouichi untied Kouji and dragged him down so he was seated in Kouichi's lap. "Ride my cock," Kouichi ordered, "like the tranny slut you are."

Kouji moaned in response, lost to pleasure, but began to ride his brother's throbbing cock as fast as he could. His tongue hung out of his mouth, eyes rolled back in his head.

"Fuck it." Zoe's father pulled out his cock and began to jerk off over Kouji's face as Zoe sobbed and fingered herself to another orgasm. "Don't you dare stop, Zoe. You're going to keep touching yourself until I'm done."

"Yes, daddy." Zoe rubbed her clit faster, thrusting two fingers into herself as she dreamed of being fucked by her secret girlfriend, Chiaki, and being caught and put in her place by her father.

Kouichi's eyes shone as Kouji began to beg incoherently. "You love getting fucked like a sissy, don't you, Konomi?" He gripped Kouji's hips bruisingly and began to slam up into him.

Kouji sobbed in pleasure, tears streaming down his face. "Breed me," he begged. "Oh, fuck- your cock- so good- fill me up- Nii-san!"

"You want me to breed you?" Kouichi thrust faster. He wasn't going to last.

"Pleeeeease," Kouji slurred as Zoe squirted all over the grass.

Zoe's father cursed and jerked himself faster, cumming all over Kouji's face. Without even thinking, Kouji swallowed what landed in his mouth.

Kouichi gripped his throat. "What a good whore." He sped up, skin slapping against Kouji's as his brother struggled for breath. His cock twitched and he tightened his grip, and Kouji clenched down on him like a vice as he came with a broken cry.

Kouichi thrust faster, squeezed harder, but Kouji didn't fight back, still orgasming. "I'm going to cum deep in your pussy," Kouichi growled, "and turn you back into my pretty little sister."

"Yes," Kouji choked out.

Kouichi groaned and slammed into him a final time. Kouji whimpered as he orgasmed again from being filled, tongue hanging out of his cum-stained face.

"What a good slut you are, Konomi," Kouichi praised. Kouji nodded, whimpering as Kouichi pulled out, but he quickly replaced his cock with his fingers, pressing his cum deeper into his brother. "Say it."

"I'm a good cockslut for nii-san," Kouji moaned.

"Good girl," Kouichi murmured, not failing to notice the way Kouji tightened around his fingers at the praise. He waved goodbye to Zoe and her father as they left, but Kouji was too far gone to even notice them leaving. "I'm going to get you a pregnancy test tomorrow," he said once he had Kouji's attention. "And if it's not positive, I'm going to rail you every day before uni until it is. Understood?"

"Yes, nii-san," Kouji whispered.

"Once you're pregnant, there'll be no more of that boy nonsense." Kouichi gripped Kouji's cheeks. "Now rub that cum into your face and go home."

Kouji nodded and obliged. He pulled his pants and boxers on, but his shirt was still ruined. He would have to hold it shut on the way home and hope no one decided to use him again.

Kouichi smiled. "Don't worry, Konomi," he soothed, "we're going to have so much fun."

Kouji nodded and smiled prettily for him as Kouichi's cum leaked into his boxers. "Thank you, nii-san."

Hope you enjoyed, should I do more of this stuff?
