Guide to tamming vilanesses-Chapter 80: Disciplining the Brat Sister Part IV

"From now on, you must change, " Shin said with a final tone. 𝑓𝘳𝑒𝑒𝓌𝘦𝘣𝘯ℴ𝑣𝘦𝑙.𝘤𝑜𝑚

Tomoko agreed with a small nod; she couldn’t protest anymore.

"Just do as I say, ok?" he asked, reinforcing his dominance over her.

Once again, she agreed with her head. Shin smiled seeing it. Things were going perfectly well.

"So, what should I do?" She asked with an obedient tone.

"Monday morning, you will find that boy in the gym. You will apologize to him, publicly, in front of whoever is there. You will tell them you lied. And then you will never, ever do anything like that again."

"But my reputation..." The words escaped before she could stop them.

"Should have thought about that before you destroyed his reputation." Shin’s eyes held hers. "This isn’t negotiable, Tomoko. It’s not a suggestion. It’s what you’re going to do to become someone who deserves Ana’s friendship. Someone who deserves to be trusted."

Tomoko couldn’t say anything. And if it were to keep her friendship with Ana, she would do anything.

"Now about school." Shin leaned back slightly against a wall. "Your teacher emailed Mom last week. Care to tell me what it said?"

Tomoko’s mouth opened, closed. Her thighs pressed together unconsciously, a response she didn’t fully understand.

Her body burned under his intense gaze. It was almost like she was enjoying it.

"She said you’ve failed two quizzes. That you sleep in class. That’s when she tried to talk to you about it, you told her to mind her own business..."

The list of problems she had caused went on and on. Some were just small incidents. Others had been clear cases of bullying, or even more serious situations.

"If you keep this up, they may even expel you from the volleyball team, you know?" Shin said.

Once again, Tomoko trembled as she thought about the consequences. For the first time, she was truly being forced to face the results of her actions.

She could no longer act as if the world revolved around her.

"From now on, Ana will always be checking on you. If you don’t act like a good girl at school, I will personally punish you." He rested his hand on her ass again, reminding her what the punishment would be.

And just for a second, Tomoko wished he would punish her more. But soon, she dismissed that thought.

"Do you understand?" He asked with a commanding tone.

"Yes." The word came out breathy.

"What was that?" He gave her a light smack on her ass.

"Yes, brother." Louder this time, her voice trembling. "I will do everything you tell me to do!"

"Good girl." The praise washed over her like warm water, and she hated how desperately she wanted more of it. How her body leaned toward him without permission.

"Now we need to make sure you remember our conversation and remember never to cross the line again." Shin’s hand settled on her shoulder, fingers pressing gently. "I will give you a spanking until you understand how to be a good girl."

Tomoko’s heart hammered. Her ass still burned from before, tender and sensitive. The thought of more was scary. She didn’t think she would be able to hold off this time.

"Position."

She moved without thinking, lowering her upper body again, presenting herself. T

The first spank landed on the underside of her right cheek, where skin was most sensitive. Tomoko gasped, her fingers curling against the carpet.

"One... thank you..."

Smack. Left cheek, same devastating placement.

"Two... thank you..."

By the fourth, she was rocking slightly with each impact, her body finding rhythm in the pain. By the sixth, she realized with horror that she was wet, soaking wet, the evidence of her arousal slick against her thighs.

No. Not in front of Ana. Please not in front of Ana. She thought.

The seventh spank landed harder, and something shifted inside her. A coil began winding tight, deep in her belly, the same dangerous sensation she’d fought off before.

"Eight." Shin’s voice seemed far away. "Count, sis."

"Eight... thank you..." The words came out strangled.

Smack.

"Nine... thank you... please..." She didn’t know what she was pleading for, mercy or continuation or something she couldn’t name.

The tenth landed with precision, and the coil snapped.

Tomoko’s orgasm crashed through her without warning, her body convulsing, a choked cry escaping as she climaxed on her knees with her ass in the air and her best friend watching.

The humiliation was absolute. But it somehow made the pleasure impossibly more intense.

When the spasms faded, she collapsed completely, face buried in the carpet, sobs shaking her shoulders.

"Look at me, sis."

She couldn’t. She couldn’t possibly.

"Tomoko. Look at me."

Somehow she found the strength, lifting her tear-streaked face, her expression ravaged with shame and lingering pleasure.

But even after all that humiliation, Ana was not looking at her with disgust. On the contrary, her best friend seemed excited with all of it.

And, somehow, seeing how Ana reacted made Tomoko feel more comfortable. Maybe she wasn’t so weird. Maybe she could submit to the darker desires of her body.

"From now on, will you be a good girl?" Shin asked?

"Yes... brother..." Tomoko’s voice was raw, her body trembling on the edge of another fall.

Smack.

"Two..." She was counting again, she realized. She’d lost track of how many rounds they’d done. Her mind felt fuzzy, and every sensation was amplified.

"You will listen to Ana when she tells you to study. You will not argue. You will not make excuses."

"Yes... thank you..."

Smack.

"Three... please... I’ll be good... I’ll be so good..."

The promises spilled from her between gasps, and each one felt true.

Amidst the speaking, her second orgasm built slowly but hit harder, tearing through her as Shin’s hand connected with her huge and sexy ass. She sobbed through it, her body clenching around nothing, desperate and exposed.

"Please... no more... I can’t..."

But she could. And she did.

The third time, she came without being touched at all, just the anticipation of the next spank was enough.

And what pushed her over the edge was the sound of Shin’s voice telling her she was doing well. She shattered completely, her cries muffled by the carpet.

When the spasms finally faded, she lay completely still, boneless and broken in the most beautiful way.

After all of that, Shin’s hand settled on her back, grounding her. "Breathe, sis. Slow and deep. You’re okay."

The kindness in his voice after everything made her feel at ease. She was relaxed because she knew her brother would take care of her.

All she needed to do was to be his good girl.

"Ana," he said quietly, "can you get her some water?"

Ana moved immediately, returning with a bottle of water. She knelt beside Tomoko, brushing hair from her friend’s damp face.

"Hey," Ana whispered. "You did so well. You’re okay."

Tomoko turned her face toward the voice, and something in Ana’s expression made her breath catch. Ana’s cheeks were flushed. Her pupils were dilated. And when she shifted, her thighs pressed together in a way Tomoko recognized intimately.

She was turned on. Watching everything. Ana was turned on watching her.

The realization sent a fresh wave of heat through Tomoko’s exhausted body. Her pussy, already oversensitive, throbbed with impossible need.

"I think," Ana said softly, her eyes never leaving Tomoko’s, "someone needs more than water."

Her hand moved to Shin’s waistband.

Tomoko watched, transfixed, as Ana’s fingers worked the button of his jeans. As she pushed the fabric down. As his cock sprang free.

It was the same cock she had seen at a glance that day.

But seeing it up close like that, it was even more impressive. The thick shaft stood hard and proud. It was heavy, impossibly large, pulsing like a beast.

Tomoko didn’t want to admit it, but her pussy clenched. Something instinctive woke in her, seeing that monster.

Just like her mother, her sister, and her aunt, she was a size queen. And a cock, some big made her mouth water and her thighs clench simultaneously.

"Oh god..." The whisper escaped before she could stop it.

Ana’s hand wrapped around him, stroking slowly, her eyes flicking between Tomoko’s face and the evidence of Shin’s arousal.

"Look at what you did to him, you made him this hard."

Tomoko couldn’t look away. Her body, which should have been spent, was burning again. She was aching, and her pussy felt so... Empty. She wanted... God, she wanted that big cock.

She wanted to be filled and claimed and owned in ways she’d never let herself imagine.

"Please..." The word came from somewhere primal, beyond shame, beyond resistance.

Shin’s eyes met hers, dark with want. "Please what, sis?"

But before she could answer, Ana leaned close, her breath warm against Tomoko’s ear.

"So, what do you think of us working together to satisfy him? I can reassure you, there is nothing better than his cock," Ana said smugly.

Then she removed her clothes in a second.

"Please, Stund, use me to show your sister how good it is to be fucked by a man," she murmured, presenting her pussy to him.
