Umaru laid down on the bed with a cock in her mouth. She laid on her back with her head hanging slightly off the edge as her hair fell gracefully to the floor. Taihei stood next to the bed, holding her head steady with one of his hands. He took a handful of her breast as he fucked her mouth slowly. Her nipples were pointed and perky, just how he liked them. He kept the room purposefully a bit cold so that they always would be. He ran his fingertips around them in a circle before pinching them hard.

Ever since he had done what he had, Umaru had become more and more passive. At first, she had been furious. She went on and on about going to the police. She told him that she would run away. That she would get help. She told him that he would go to jail for what he had done. That he would rot in a cell for forcing her to do the things he had. For forcing himself upon his little sister, of all people.

Taihei had quickly put an end to that behavior. He had found it amusing that she was so fired up about it, but he couldn't have her blabbing to the police. There would be no going back after what he'd done. If he let her go, his life would be over. No, he would have to keep her under control from now on. Which wouldn't be so bad. Now he could have his way with her whenever he wanted. So long as he kept her on a leash.

So he put an end to all of that. When she tried to leave through the front door, he would beat her. He would grab her by the waist, throw her to the ground, and pummel her into submission. Then once she was so bruised and bloodied that she couldn't resist, he would fuck her for good measure. He would shove his cock down her throat, up her snatch, up her ass. He would cum inside of her and all over her body. It didn't matter which. He owned her now.

Taihei felt a surge of satisfaction ripple through his body. Never before had he felt so powerful, so strong. His pathetic little sister was now completely under his thumb. She was his to dominate. And she couldn't do a god damn thing about it.

Umaru laid on the bed in front of him naked and bruised. It had been a couple of days, but she still hadn't healed completely from the previous beating. She just laid there obediently as he thrust his cock deep down her throat. Her eyes were dead and she barely responded to anything. She didn't even seem to have a gag reflex. Taihei was rock solid as he pushed his cock inside of his sister's mouth as deep as it would go, all the way down to his balls. His balls hung sloppily downwards, falling over her nose and past her eyes.

A shiver rushed through his body as the warm and wet sensations of her young, supple tongue and saliva started sending him over the edge.

He could hold it in no longer. With a grunt he released his load inside of her, painting her throat with his seed. Umaru's chest heaved, her breasts jiggling slightly, and she let out a series of muffled coughs. He felt a gargle of semen and puffs of air as Umaru choked on his cock and sperm.

He pulled out. He couldn't have her choking to death. Taihei was many things, but he was not a necrophiliac. He needed her alive. Umaru's chest heaved again and she coughed and sputtered. A thin line of cum and saliva connected her lower lip to the tip of Taihei's penis as he gave her a moment to breathe.

He should sit her up. He took Umaru by the shoulders and forced her upright. Cum billowed out of her mouth like a waterfall, dripping slowly off of her chin. A trickle of it dripped onto her tits as gravity pulled it down. She heaved again, a small amount of semen spurting out between her lips as she coughed up a mouthful. Taihei smirked. What a wonderful sight.

Without warning, Umaru started to heave uncontrollably. Her chest pulsated three or four times, her boobs shaking slightly with each heave. Taihei knew what was coming. And he didn't want it all over his bed. He dashed to the kitchen, grabbed a large bowl and took it back to her. Just in time he placed it underneath Umaru, who puked violently into it. He stroked her hair gently as she dry heaved a couple times before vomiting again. After a few more coughs and gasps for air, it seemed she had finished. Taihei continued stroking her hair as he rubbed his still erect penis back and forth on the side of her thigh. It seemed he had overdone it a bit this time. Never before had she puked like that. At least she was still breathing.

He took the bowl away and set it aside. He would clean it up later. He looked back at Umaru. She was filthy. Cum and vomit spattered her from her chin to her tits. As much as he enjoyed seeing her in such a ruined state, he couldn't have her stay like this for long or she would get it all over the apartment.

"Get in the shower," he said, "We need to clean you up."

Hoisting her up by the armpits, Taihei led her to the shower. She could still walk, but Taihei had to guide her. The pain from the previous beating must still have been severe. He sat her down on the shower floor and turned on the water. He left her there in the stream of water and closed the door behind him. He had quite the mess to clean up while the shower did its work.

Once he had cleaned everything up, he felt that he needed a shower too. He walked into the bathroom. Umaru was still sitting in the tub, cleaner than she had been but sitting in the exact same spot with cold, dead eyes. He felt the violent urge to empty his balls again. He turned off the water.

Climbing into the tub with her, he began to violently masturbate.

"Who's my little whore?" He said through clenched teeth, "Who's my fucking cumslut?"

Umaru gave no reply. She just sat there, her eyes fixated on nothing in particular.

She really had no business being that pretty. She was blessed with the perfect body. Silky straight hair. Perfectly sized tits. And a slim, mesmerizing frame. Why couldn't he be like her? Why couldn't he have been born with such advantages? He was ugly by comparison. Taihei hadn't known how much luck Umaru had had in her sex life, but she certainly wouldn't have had to try very hard. Guys would be falling over themselves for a chance with her.

Not that any of them would ever get the chance. He was the only guy she would ever be with. She was his to fuck, his to do whatever he wanted with.

He pushed her mouth open with a finger until her lower jaw hung limply open. He placed his balls on her tongue, allowing them to rest lightly on top of it. He forced her to close her mouth slightly so it felt like she was sucking on them. The base of his cock rested on her nose as he stroked it vigorously.

"P-Pwease," said Umaru feebly, her voice muffled by his balls, "Pwease schtop."

He busted with a grunt, a slim shot of cum erupting from his dick. It arched straight into the air, landing in a thin line on top of her head and down her back. It soaked into her hair, oozing about gradually as it settled. He would leave her like that and let it dry.

He had had enough for one day. He would have another go at it in the morning.
