Hiro didn't stop. He kept fucking Rina's ass with long, brutal thrusts, each impact making his bound sister's body shake violently. The wet, obscene sound of his cock sliding in and out of her asshole echoed through the room, mixed with Rina's choked sobs and moans.
"Look at her, Anna!" Hiro growled, yanking Rina's hair harder to arch her back. "This is your sister. The same one who used to act so innocent. The same one who got wet when Tougo squeezed her tits. Now here she is, taking my cock up her ass like the whore she always was."
Rina cried inconsolably, tears streaming down her cheeks as her treacherous body clenched tightly around Hiro's thick cock. The pain was intense, but the forced pleasure was even worse. Every deep thrust made her moan against her will.
Anna remained frozen by the door, eyes wide open and breathing ragged. She couldn't look away. Seeing her younger sister tied up, her red and swollen ass being destroyed by Hiro, filled her with an overwhelming mix of horror, jealousy, and a sick excitement she didn't want to acknowledge.
"What's wrong, nee-san?" Hiro asked without stopping as he fucked Rina. "Does this turn you on? Does it make your pussy wet watching me punish your sister for being a slut?"
Anna weakly shook her head, but her thighs pressed together. A shiny trail of her own juices was already running down the inside of her leg.
Hiro let out a low, dark laugh. He pulled his cock out of Rina's ass with a wet, obscene sound, leaving her hole gaping and twitching. Then he moved toward Anna, his cock still hard and glistening with fluids.
"Kneel," he ordered.
Anna hesitated for only a second. Her knees gave out and she knelt in front of him. Hiro grabbed her hair and shoved his cock straight into her mouth, still warm and tasting of Rina's ass.
"Suck it," he said coldly. "Clean the cock I just used to punish your sister."
Anna moaned around his cock but obeyed. She started sucking desperately, licking every inch, tasting the mixture of fluids as tears ran down her cheeks.
Hiro looked over at Rina, who was watching the scene with swollen eyes.
"See, Rina?" he said as he fucked Anna's mouth. "Even your big sister is learning her place. You're going to learn too. And you're going to learn very well."
He pulled Anna up by her hair and pushed her toward the bed. He positioned her on her knees right next to Rina, so both sisters were side by side, exposed and humiliated.
Hiro positioned himself behind Anna and, without warning, buried his cock balls-deep into her soaked pussy.
"Ahh!" Anna moaned, arching her back.
He started fucking her with the same brutality he had used on Rina. His thrusts were hard, deep, and merciless, making Anna's breasts bounce violently.
"You both belong to me," Hiro growled, alternating between fucking Anna's pussy and shoving two fingers into Rina's still-gaping asshole. "Your bodies, your orgasms, your moans… everything belongs to me."
Anna couldn't hold back any longer. A violent orgasm ripped through her, making her scream as her pussy clenched hard around Hiro's cock. Rina, seeing her sister cum, also began to tremble, aroused just from watching.
Hiro pulled his cock out of Anna's pussy and came hard over both sisters, covering their backs, asses, and hair with thick, hot ropes of semen.
When he finished, he stood there breathing heavily, looking down at the two destroyed and cum-covered girls.
"This is only the beginning," he said in a hoarse voice. "We'll continue tomorrow. And every day you're going to learn a little more who you belong to."
Rina and Anna could only sob weakly, exhausted and completely submissive.
Hiro smiled with dark satisfaction.
The Komiya family no longer had any escape.
And he was far from finished with them.

**The next morning:**
Hiro woke up with an overwhelming sense of absolute power coursing through his entire body.
Sunlight filtered softly through the curtains of the master bedroom. Beside him, Yuria slept deeply, naked, her body covered in red marks from the night before and dried cum between her thighs. On his other side, Anna was curled up against him, her eyes still swollen from crying and moaning so much. Even in sleep, her expression was one of complete submission.
Hiro smiled with deep satisfaction.
He got up quietly and walked naked down the hallway to Yuria's room. He opened the door, and there was Rina — exactly as they had left her the night before.
She was still tied in the same humiliating position: arms stretched upward, legs spread wide apart, a red ball gag in her mouth, and the vibrator still buzzing weakly inside her swollen, red pussy. Her body was covered in dried cum, her hair sticky, and her eyes half-open, exhausted.
When she saw Hiro, Rina let out a weak, trembling moan against the gag, begging with her eyes.
Hiro approached slowly and stopped in front of her. He caressed her cheek with fake tenderness.
"Good morning, little sister," he whispered. "Did you sleep well?"
Rina shook her head, fresh tears welling up.
Hiro let out a low, dark laugh, filled with pure satisfaction.
He felt… euphoric.
For the first time since arriving in this world, he felt that everything was exactly as it should be. Three beautiful, voluptuous women who were completely his. Three women who, just weeks ago, looked at him with contempt or indifference, now trembled, moaned, and begged under his control.
He could do whatever he wanted with them.
Whenever he wanted.
However he wanted.
He leaned down and removed the ball gag from Rina's mouth. She gasped, desperately sucking in air.
"Hiro… please… I can't take it anymore…" she sobbed. "I'll do whatever you want… I'll be your whore… only yours… but please, let me down…"
Hiro stroked her hair gently, almost affectionately.
"Not yet," he replied calmly. "You still haven't learned your lesson completely. But don't worry… you'll have all day today to reflect."
He put the gag back on, ignoring her new sobs, and turned the vibrator up to maximum power. Rina shook violently, moaning against the ball as her exhausted body was forced to feel pleasure once again.
Hiro left the room and went downstairs to the kitchen, where Yuria was already preparing breakfast, completely naked except for a short apron that barely covered anything. When she saw him, she smiled with devotion and quickly approached, hugging him.
"Good morning, my love," she whispered, kissing his chest. "Did you sleep well?"
Hiro grabbed her ass with both hands and squeezed it hard.
"I slept like a king," he replied, kissing her possessively. "Because I have three beautiful whores who belong to me."
Yuria shivered with pleasure at his words.
Anna came down the stairs a few minutes later, also naked. She had visible marks on her breasts and thighs, and walked with slightly shaky legs. When she saw Hiro, she immediately lowered her gaze, submissive.
"Good morning… Hiro," she murmured.
Hiro approached her, lifted her chin, and gave her a deep, almost possessive kiss.
"Good morning, my big whore," he whispered against her lips. "How's that pussy feeling this morning?"
Anna blushed intensely but didn't pull away.
"…Sensitive… and full of you," she admitted in a low voice.
Hiro smiled, genuinely happy.
He sat at the head of the table while the three women served him naked. Yuria made his coffee, Anna served breakfast, and Rina… Rina was still upstairs, tied up and vibrating, paying for her betrayal.
As he ate, Hiro watched them with deep, dark satisfaction.
He could fuck them whenever he wanted.
He could humiliate them.
He could punish them.
He could share them or keep them all to himself.
They no longer had any will of their own when it came to him. They existed only to please him.
And that… that made him immensely happy.
He finished breakfast, wiped his mouth, and looked at the two naked, obedient women standing beside him.
"I'm going out for a while today," he announced. "When I come back, I want Rina still tied up. And I want both of you ready for me. Naked, wet, and eager to be used."
Yuria and Anna answered in unison:
"Yes, Hiro."
He smiled, stood up, and kissed both of them possessively.
He left the house feeling like a god.
The world was his.
And the Komiya women… were his greatest treasure.
And his greatest toy.
