The Komiya family gathered in the dining room to have lunch together. No one spoke, but a strange atmosphere could be felt in the air.
Hiro ate quickly because he was exhausted. Cumming over and over again with Yuria in the bathroom hadn't helped much.
Anna didn't say a single word during the meal, while Rina kept glancing at him from time to time.
When they finished eating, Anna offered to wash the dishes while Rina stayed in the living room chatting on her phone.
"Rina, can you help me for a moment?" Yuria suddenly said to Rina. Although she asked politely, her tone made it clear that she wouldn't accept no for an answer.
Rina looked up, a little surprised, but still agreed. "Yes, Mom."
Together they got up from the sofa and walked down the hallway of the house. Yuria opened the door to her bedroom and went in first.
Rina was a bit curious to know what her mother could possibly need help with in her room.
Then suddenly… two strong arms grabbed her from behind. One arm wrapped around her chest, pinning her arms and restricting their movement.
The other hand went straight to her face, specifically to her mouth. The palm covered her mouth, preventing her from letting out any scream of panic or fear.
Rina's eyes widened in terror. She tried to struggle free from the embrace, but she was much weaker than the person holding her.
With a look full of panic, she stared straight ahead, desperately seeking help from her mother Yuria. But what she saw made her eyes open even wider, freezing her in complete shock.
Her own mother, Yuria… walked toward her holding a long rope, a huge smile on her face, and began tying her legs.
Rina looked down in disbelief as Yuria, after immobilizing her legs, also grabbed her arms and tied them tightly behind her back.
Only then did the person who had been holding her step into clear view.
It was Hiro!
Hiro released Rina's mouth. She stared at him in confusion as he quickly sealed her mouth again with a strip of silver duct tape.
In just a few seconds, Rina was completely tied up and gagged!
Hiro stared at her with a cold, unfriendly expression, clearly enjoying her shocked and terrified face.
"Mom, you know what to do."
Yuria nodded with a chilling calm, as if this was something they had planned for years.
She walked over to the closet in her room and pulled out a small wooden box that Hiro had never seen before.
Hiro was curious about what was inside, but he preferred the surprise.
"You take care of her. In the meantime…" Hiro opened the door and stepped out. "I'm going to have some fun with my big sister."
Yuria's cheeks flushed with excitement and she nodded with a smile.
With firm steps, Hiro headed to the kitchen where Anna was calmly washing the dishes.
He approached silently and grabbed her ass with his left hand.
Anna jumped in surprise, but Hiro pushed her back down with his right hand, forcing her to stay bent over.
Hiro smiled maliciously as his left hand sank deeper into Anna's round, firm ass. He squeezed it slowly, feeling the soft flesh mold under his fingers, then spread her cheeks slightly, enjoying the way his older sister tensed up and let out a small, muffled gasp.
"Shhh… easy, Anna," he whispered close to her ear, his voice low and husky. "I'm just going to play with you for a while."
Anna tried to straighten up, but Hiro's right hand on her back kept her firmly bent over the sink. His fingers continued massaging and kneading her ass cheeks over her skirt, squeezing, spreading them, letting the fabric slide between her crack. With every movement, Anna shuddered, her still-wet hands gripping the edge of the sink tightly.
Hiro slid his hand down to the hem of her skirt and, with deliberate slowness, lifted it little by little. First he revealed her soft thighs, then the edge of a pair of simple white panties that contrasted with Anna's lightly tanned skin. He pulled the skirt all the way up until it was completely bunched around her waist, fully exposing her ass.
"So pretty…" Hiro murmured, running his open palm over the thin fabric of her panties, feeling the heat radiating from his sister.
Without giving her time to react, he hooked his fingers into the sides of her panties and yanked them down to her knees in one swift motion. Anna's ass was now completely bare: two perfect, round, soft cheeks with a slight gap that revealed the beginning of her pussy.
Hiro knelt behind her without releasing the pressure on her back. He brought his face close and blew gently on her exposed skin, making Anna flinch. Then, with both hands, he firmly spread her ass cheeks, completely exposing her pink asshole and the swollen lips of her vagina.
"Mmm… you're already a little wet, little sis," he said mockingly.
Without any further warning, Hiro stuck out his tongue and slowly licked from her clit all the way up to her asshole, savoring her with delight. Anna let out a choked moan and her legs trembled. Hiro repeated the motion, licking with more pressure this time, stopping at her clit to circle it with the tip of his tongue before sliding back up, hungrily licking her entrance and her tight little hole.
His hands kept her ass cheeks spread wide while his mouth worked mercilessly: sucking, licking, and slurping, alternating between her dripping pussy and her clenched asshole. Every time his tongue pressed against her small back hole, Anna clenched and let out a broken sound.
Hiro looked up for a moment, admiring how his sister's ass moved involuntarily against his face, seeking more contact despite the shock.
"Tastes delicious…" he growled against her wet skin, before pushing his tongue deeper into her pussy, fucking her with it while his nose rubbed against her asshole.
Anna gritted her teeth and squeezed her eyes shut, her body betraying her as pleasure began to invade her against her will. Hiro had no intention of stopping anytime soon.
