Guide to tamming vilanesses-Chapter 37: New rules **

Of course, after seeing her tits, Shin asked Yumemi to let him touch them. The girl complained a bit, but finally leaned in.

And soon her brother was groping her boobs. To her surprise, Shin was extremely skillful with his finger.

The asshole lightly brushed her nipples, making her hornier and hornier. She tried to hide it, but a soft whisper still escaped her lips.

She saw him smiling confidently. "It was not a moan!" She protested, but the truth was clear.

"It’s fine to enjoy it," he murmured with an arrogant smile. "Because I’m enjoying it alot, your boobs are great."

She didn’t say anything. She was trying to pretend it wasn’t happening, that he wasn’t actually touching her bare skin.

Still, time went down and he kept massaging them. Yumemi wondered how long it would take for him to be content.

The worst thing was that the longer he played with her, the hornier she became. She could feel a treacherous pleasure growing in her womb.

Normally they say girls take a long time to cum, but Yumemi was an easy climaxer. If she were a man, they would say she had premature ejaculation. But, to her luck, a woman could cum as much as she wanted during sex and keep going.

However, at that moment, this was hell. She did everything she could to keep herself from climaxing, but it kept building... a hot, insistent pressure coiling tighter with every second.

She clenched her thighs, bit her lip until she tasted blood. She tried to focus on the shame, the wrongness of it all.

It was no use.

The orgasm broke over her not in a wave, but in a sharp, shuddering gasp. Her back arched, as her entire body tensed and a rush of heat pulsed through her core. It was small, intense, and utterly betraying.

Shin looked up at her flushed face, her tightly shut eyes, and the faint tremors still dancing across her skin. A slow, knowing smile spread across his face.

"Well, well," he murmured, his voice thick with amusement. "Was that what I think it was?" He gave her other breast a deliberate, possessive squeeze. "Couldn’t help yourself, could you, slut sister?"

"Don’t call me a sluahnt!" She tried to complain, but a small moan tore from her mouth as he pinched her nipples again.

Yumemi’s cheeks burned with humiliation. Too ashamed to make eye contact, she made the mistake of looking down.

Her eyes, of course, immediately found that monstrous thing between his legs.

The sight stole the air from her lungs.

Shin’s cock was a thick, intimidating length of flushed flesh. The veined shaft led to a broad, ruddy head that already glistened faintly with pre-cum. That thing was not just a cock, it was a pussy-destroyer.

The sight of it, bare and so close, made her stomach clench with a dizzying mix of terror and a horrifying, unwelcome flicker of desire.

The sight made her pussy tingle. And she hated herself for it. Yumemi tried to ignore it. She tried to ignore everything, closing her eyes and desperately pretending she was somewhere else.

"I see you’re in love with my cock," Shin smiled arrogantly, his huge shaft throbbing with a confidence that seemed to fill the room. "Touch it," he ordered.

A traitorous part of her had already desperately wanted to wrap her hand around that monster, and his command gave her the perfect, shameful excuse.

She shouldn’t do it. She knew it was dangerous. However, before she fully realized it, she was moving. Her fingertips, trembling slightly, brushed against the slick, broad tip of his cock.

Yumemi teased his head. She couldn’t help herself; a compulsive need to play with it overwhelmed her. She was shocked at her own actions. This was her brother’s cock. But it was too manly, too strong.

"You like that?" Shin asked, his voice husky as she ran her fingers along the sensitive vein on the underside.

"You have a half-decent cock," she tried to say dismissively, pretending she wasn’t utterly captivated.

He took her hand firmly in his and wrapped her fingers around his shaft. They barely closed around its impressive girth.

"Jerk it, slut," he ordered, his tone leaving no room for refusal.

And she did. She jerked his cock slowly, tentatively at first, then with a growing rhythm.

At each stroke, that huge thing reacted with a happy throb. It was almost cute, and Yumemi couldn’t resist the desire to make it cum.

Then a sexy image bloomed in her mind: she wanted him to cum all over her. She wanted to feel that big cock pulse and shoot its hot cum all over her skin.

However, soon the throbs of happiness stopped.

"Don’t you even know how to jerk a cock?" Shin complained, and pushed her away.

Yumemi should have been happy, but she felt almost heartbroken, departing from that huge, perfect cock.

"Put your hands behind your back and tits out like you’re on display. Hold that pose so I can at least use you to jerk off."

The sister felt utterly humiliated, but she still did as he ordered. She could not confront him, and a desperate, secret part of her was eager to feel him painting her with cum.

She assumed the position he wanted: on her knees, back arched to thrust her chest forward. With her hands locked behind her, the pose pulled her shoulders back, making her breasts jut out defiantly.

They hung full and heavy, swaying slightly with her rapid breaths. The pink peaks were tight and exposed, presented for his use alone.

Shin noticed her eyes wide and fixed on the thick cock.

"Well, look who’s finally paying proper attention," he taunted, wrapping his hand around his shaft and giving it a slow, deliberate stroke. "See something you like?"

"It’s... it’s scary and grotesque," Yumemi breathed, the protest weak even to her own ears. A horrified fascination held her captive. "How big is it, anyway?" The question slipped out, whispered and awed.

"Big enough," he grunted, pumping himself slowly now, his eyes locked on her. "Just stay still."

Yumemi froze, kneeling before him, her lips parted and wet, her eyes wide. She watched, mesmerized and mortified, as his fist became a blur on his shaft. His breaths turned to ragged pants, his knuckles white. 𝕗𝐫𝚎𝗲𝘄𝐞𝕓𝐧𝕠𝘃𝕖𝐥.𝐜𝚘𝚖

"Watch," he commanded, his voice thick. "Watch me cover that pretty, useless face."

She couldn’t look away. His whole body tensed, a tendon standing out in his neck. With a final, guttural groan, the swollen head pulsed and the first thick, hot stripe of cum landed across her cheekbone. The next shot painted her lips. Another splashed across her forehead and into her hair.

And he would not stop cumming, painting her tits, cheeks, and clothes. Yumemi couldn’t hide her admiration for such a big load.

She had made a few guys cum in the past, and none of them had come close to this much

Shin looked down at her cum-streaked face with dispassion. "Clean it up."

When she just stared, trembling, he nudged his still-wet cock against her lips. "With your mouth. Consider it your first lesson in being useful."

A hot wave of shame crashed over her, but beneath it, that traitorous flicker ignited. She leaned forward, tentatively licking the base of his shaft.

The taste was salty, musky, and overwhelmingly masculine. She worked her way up, her small tongue cleaning him with a mortifying diligence.

When she reached the tip, she opened her mouth as wide as she could, and slowly took him in.

To both their surprise, she managed to take almost half of his length, her gag reflex stifled by sheer desperation and a twisted sense of challenge. She bobbed her head clumsily, her technique all instinct and no skill.

After a minute, he pushed her back with a sound of disgust. "Pathetic. You’re worse than I thought. Useless."

The words stung more than any slap. She would never admit it, but his words were like a punch to her pride.

"Well, I think you’re useless as a sex slave," he stated. "So you’ll just be my slave. New rules."

"I’m not going to be your slave!" she spat, finding a last shred of defiance.

"Shut up." His voice was low and absolute, freezing the protest in her throat. "You can put your clothes back on." He said it while looking at her exposed body with clear disinterest, which humiliated her even more.

As she hurriedly covered herself, he laid out his edicts.

"You will sleep by eleven and wake at six. You will do all the household chores. When I message or call, you answer immediately. Any task I give, you complete. If you want to go out, you ask my permission first."

Shin was actually going to force her to have discipline and improve. He didn’t need blackmail to have sex with her, she would eventually beg him for sex.

"This is insane! You can’t..."

"I can. Unless you want your life destroyed. Do you understand?"

She looked down, clenching her fist in frustration.

"Yes..."

Finally, he asked, "Where’s Tomoko?"

"She went running with Ana. She’ll be back soon," Yumemi answered, her voice small and submissive.

Shin was silent for a moment, thinking. "Get out of the house for the afternoon. Don’t come back until evening."

"What? Why? Where am I supposed to..."

He began to count. "One."

The color drained from her face. She turned and fled the room, the sound of his voice chasing her down the hall. "Two."

Her desperate footsteps echoed through the silent house as she hurriedly dressed and went out.

Now he just needed to set the stage, to have the first event with his second younger sister: Tomoko.
