Guide to tamming vilanesses-Chapter 36: Blackmailing my sister*

Shin had purposely made a show of jerking off, so his sister could see. And even after she entered the room, he didn’t hide his huge cock.

On the contrary, he made sure she would have a perfect view of it. And even if Yumemi wanted to avoid it, her eyes kept darting down to glance at that monster.

"Disgusting brother!" she hissed, trying to bury her own lust beneath performative rage. "Were you masturbating to a picture of me? Put your disgusting cock back in your pants. It stinks, and I don’t want to look at it."

She needed to keep a strong front; if she acted too submissive from the start, he would walk all over her. Yumemi was sure her brother was just a horny loser, probably so desperate for her that he couldn’t control himself.

Honestly, seeing him like this gave her a twisted confidence boost. It was proof of a power she held, the power to make men burn with want for her body.

She was used to manipulating men with her body, making them her servants.

She felt confident that if she put on a strong front and pretended to have the upper hand, she could escape this situation without having to do much for him.

However, her bluff was useless against Shin.

He had staged everything precisely so she would believe she held some power in the situation.

"’I believe you should behave better, sister,’ Shin said, turning the tables. His domineering voice made her tremble."

Maybe she had made a mistake trying to act tough. Her body was already trembling. After all, she was not a strong girl; she was a coward.

"Or perhaps you are an exhibitionist slut? Do you secretly want me to reveal the photos to everyone?"

"Never!" she screamed, showing her true emotion. Her body was trembling, her eyes desperate.

"Very well," Shin smiled, and his huge cock throbbed, catching the girl’s attention.

Yumemi’s breathing grew heavy as fear tightened around her chest. She was terrified, feeling like a caught prey.

She tried to move her leg just to take a step back, but she couldn’t. Her body was frozen in place, her mind unable to think straight.

Honestly, Shin didn’t expect it to be so easy. His sister really was a coward.

"Ok, now, if you don’t want me to show the evidence to anyone, you’d better do what I say," he declared with a warmer tone.

If his sister just froze from fear, he wouldn’t be able to progress toward his goals.

"And... what do you want?" she asked, her voice trembling, caught somewhere between defiance and fear.

"Why don’t you start by pulling your top down and giving me a peek at those titties, sis?" he said.

Goosebumps broke out over Yumemi’s skin. Her body trembled with a volatile mix of emotions, and she hugged her own torso tightly. It was an unconscious, defensive motion that had the effect of pushing her big breasts upward.

Her cheeks flushed a deep crimson. She wasn’t wearing a bra, and her nervous movements made her full breasts bounce.

"Are you serious?" she asked, trying to keep a mask of defiance. However, she was actually thinking that just showing her boobs was not a big deal.

She had never shown them to any other man, at least not in person. However, she had posted more than one pic of her naked tits.

"Of course I am."

His gaze dropped purposefully to her chest, staring like a horny adolescent. And he made his huge cock twitch, its broad head pulsing.

Yumemi gulped hard, seeing it. Against her own will, a detached, artistic part of her mind ignited. She desperately wanted to take a picture of that veiny thing; it would be perfect as a reference for her manga.

She had searched for many dick pictures to improve her drawings, but she had never come across a cock so blatantly erotic. Not even in the manga she read had she seen something so imposing and manly.

"Shin, I’m your sister." She screamed, trying to ignore her lewd thoughts.

"You have 5 seconds to obey," he answered concisely. "One... two... three..."

All doubt dissolved from her mind. She didn’t have a choice. With trembling hands, she pushed her pajama shirt up. The scene wasn’t particularly sexy; she moved with a desperate urgency.

However, what came next was undeniably hot. As she finally pulled the shirt over her head and tossed it aside, her full breasts bounced freely, defying gravity for a brief moment before settling. Her rock-hard nipples pointed accusingly at Shin.

It was almost funny, because unlike her aunt, who had obscenely large nipples and areolas, hers were small and cute. Just a pair of small pink dots, a stark contrast against the pale, perfect swell of her flesh.

"Satisfied, pervert?" she asked, her voice aggressive.

Shin didn’t answer with words. His eyes were locked on her chest. He even let his jaw go slack, pretending to be so mesmerized he couldn’t form a reply.

But his cock answered for him, throbbing angrily. It was proof of how much he wanted to bury himself between her perfect breasts.

Yumemi didn’t want to admit it, but a perverse thrill shot through her at seeing him so utterly captivated by her exposed body. It made her feel powerful again.

"Damn, Yumemi," he finally breathed out, the feigned awe in his voice laced with genuine hunger. "I knew they were huge, but seeing them... they’re just too perfect." He stopped, shaking his head as if truly unable to find words worthy of them.

A small, involuntary smile tugged at the corner of her lips at his speechless praise. Yumemi had a profound weakness for compliments. She craved them, and even in this horrific situation, that part of her preened at his stunned admiration.

Just like that, kept taking her on an emotional rollercoaster, from fear to power. She hadn’t realized it yet, but he had her wrapped around his finger.
