Introduction chapter. Hitoshi is a nasty big brother and a piece of shit. But that's what you sinners came for.

~~~~~~~~~~

It's wrong and he knows it. The way his cock aches and throbs everytime his little sister is around. The way he fondles her little nipples until they start to peak underneath his fingertips. But he's weak for the squeals that leave her when he takes the buds in his mouth and sucks hard on them, pre-cum leaking from his tip everytime he feels her nipples stiffening beneath his tongue.

She's so innocent and easy to fool. He told her that if she wants her tits to grow, she should let him play with them. His stomach fluttered when she grinned and pulled up her t-shirt, showing him her flat tummy and the itty bitty mosquito bites on her chest. She let out multiple whines as he roughly squeezed and pinched her nipples, knees shaking violently.

Hitoshi was ruthless with his assault on her poor chest. Pinching, tugging, rolling the nipples around so effortlessly. Occasionally leaning down to flick them with the pad of his tongue and blowing cool air on them.

"T-toshi....h-hurts...Ow!" She closed her eyes and whimpered, shuddering under his touch. She felt something sticky pooling between her legs and it made her uncomfortable. She made an attempt to keep her legs closed together, not wanting him to tease her about peeing her pants.

"Gotta make them grow. Don't you want a nice rack when you get older?" He smirked, massaging the sore and bright red nubs between his fingers.

Giving her a moment of relief, he pulled his hands away and wrapped them around her waist. It was so easy to lift her. She was so light and weighed close to nothing. He whispered in her ear, "Sometimes when I'm playing with your tits, you're gonna get nice and sticky down there for me. It's normal. Means you want me to play with your cunt too. Can I play with your cunt, Eri?"

Eri didn't know that word. She also didn't know why she got sticky "down there." She wrapped her arms around Hitoshi's neck and nodded hesitantly. "Feels icky....really icky and sticky!"

Hitoshi chuckled at that and laid her down on the carpet in the living room, relieved that their adoptive father was working a double shift and wouldn't be home until morning. Meant he had all evening to play with Eri. He couldn't wait to give her her first orgasm. Maybe fuck her tight little slit with his tongue until she was quivering and cumming all over his face.

He spread her out gently and spread her folds apart with his index fingers, exposing her virgin pussy to his lustful eyes. His cock was so hard that it hurt, desperately straining against the fabric of his gray sweatpants. God, he wanted to fuck her so bad. Wanted to pick her up and bounce her on his cock like there was no tomorrow. But he had to be patient and he needed to go slow. The last thing he wanted was to hurt her by rushing things. Especially after he already had her in his palms like Silly Putty.

Eri whimpered and tried to close her legs, but Hitoshi spread them back apart and looked her in the eyes, his expression soft and full of adoration. "I love you, Eri. It's okay. I won't hurt you. Do you trust me?"

Eri's cheeks tinted a shade of scarlet and she nodded, nervously biting her bottom lip. "I don't like being sticky."

"I know, princess. But it's good. Easier for me to get you ready for my cock."

Before Eri had a chance to say anything in response, she cried out in ecstasy and threw her head back. Hitoshi was using her own slick to play with her little pink clit, circling the sensitive organ with the pad of his thumb. She seemed to enjoy the feeling, desperately humping against his hand. It continued only for a few seconds, him dipping his finger into her pool of wetness to collect more fluid to use as lube and aggressively rubbing her clit until she let out such a loud whine that she made Hitoshi flinch.

"Toshi! Toshi! Aaaah! It tickles! It tickles!" Eri babbled nonstop, tears of pure pleasure rolling down her cheeks as her little body shook. Drool had began to gather around the corners of her mouth and her tongue lolled out, face still flushed with arousal. Her first orgasm had her even wetter than she was before and although she didn't like the feeling of that sticky, white goop dripping from her cunt, she couldn't complain about it. The orgasm made her head fuzzy and the room felt like it was spinning.

Hitoshi felt his chest swell with pride. She was such a good girl. So good for him. So responsive and so sensitive. He gently wiped away her tears and shushed her, kissing her forehead repeatedly. He kept whispering to her, telling her how much he loved her and how he just wanted to make her feel good.

Eri could only gasp when she suddenly found Hitoshi's mouth on her still sensitive and throbbing clit. Efforts to move away were futile because of his iron grip on her hips and she began to whine again. Her pleas and whimpers were ignored as Hitoshi sucked away on her clit and swirled his tongue around it, further encouraged the louder she cried out.

"You taste so fucking good, baby. Such a sweet fucking cunt." Hitoshi mumbled between her folds, tongue diving in and out of her hole and savoring her juices. He ran his tongue up and down her labia, being careful not to miss a single spot. The little girl tasted like heaven itself.

Eri grabbed onto his hair for support, desperately tugging at strands of indigo as her brother hungrily devoured her. She felt like a full course meal, the way Hitoshi's tongue explored her private parts and the way he refused to let up at all. She kept chanting his name like a mantra, grip tightening on his hair as that familiar feeling started building in the pit of her stomach. She was gonna cum again.

Seeming to know she was close to reaching a climax for the second time, Hitoshi's pace quickened and his tongue became more frantic. His entire mouth covered her bald pussy and the sounds of hungry smacking echoed throughout the living room.

"Fucking cum for me. Cum for me like a good girl. Be a good bitch and cum in my fucking mouth." Hitoshi growled, grip tightening on Eri's hips. He left behind red handprints on her pale skin but didn't care. Could be easily covered up if anybody asked about it.

"TOSHI, TOSHI, TOSHI!! AAAAAHHHHH! AAAHH!" Eri thrashed around as if she were having a seizure, howling like a wounded animal. She bucked into Hitoshi's mouth nonstop, hands instinctively flying up to her little nipples, still protruding and swollen due to Hitoshi's earlier abuse. Remembering how good it felt when he toyed with them, Eri tried pinching them herself as she rode out her orgasm.

"Mmm, that's my good girl." Hitoshi swallowed every drop of her juices without question and made sure to get her pussy as clean as he could manage, swiping up any leftover arousal. Due to the overstimulation, it didn't take long for her to start getting slicked up again. The carpet was completely soaked beneath her. Would have to clean that up later. Probably lie and tell Aizawa that Eri spilled a glass of water.

Eri's face was wet with tears and she couldn't stop moaning. She kept pulling on her nipples and still pathetically humping at Hitoshi's face, coating his lips, cheeks, and chin with her slimy fluids. "...Want more...want more..."

A dark grin spread across Hitoshi's face. "That's what I wanted to hear. I got a surprise for you. Don't fucking move."

Hitoshi went upstairs to his room and returned to the living room within minutes. In his hands were two wooden clothespins. Eri didn't even react. Was too far gone. Eyes closed, chest heaving up and down, tongue out, babbling nonsense that he didn't understand.

Without a word, he clamped both pins on her tiny tits and earned a high pitched whine from her. His cock was hurting at this point. He needed to be inside her. The way she was writhing around on the carpet and moaning each time he pulled on the pins that were putting pressure on her sore, abused nipples was making his cock harder by the second. He couldn't take it anymore.

Eri's eyes fluttered open when she noticed Hitoshi pulling down his sweatpants, gasp leaving her at the sight of his cock. To her, it was massive. Was she supposed to play with it like he played with her pussy? She didn't know.

After lathering himself up significantly with a bottle of lube he kept around for times when he masturbated, he instructed Eri to spread her legs out as far as she could. Lube probably wasn't needed because she was sloppily wet, but he was serious about not wanting to hurt her. He knew it'd likely be uncomfortable regardless though. Nothing he could do about that.

Eri stared up at Hitoshi as he placed both knees on her inner thighs, pinning her down and preventing her from moving. She swallowed hard when she felt him prod at her vagina with the swollen head of his cock, already wet and dripping excess amounts of pre-cum. He was going to fuck her and there wasn't anything she could do. "So big. Will it fit?"

Hitoshi's only response to that was another shit-eating grin. "You're about to find out right now."
