First day of teaching(3)*
Nao was at a loss for how to handle his current predicament. He questioned his own judgment, considering the idea that had crossed his mind.
He felt overwhelmed by a strong desire, but another part of him reminded him that this was just a hentai world, so he shouldn't hold back.
His sister's teasing had crossed a line, and now his mind and body were on the brink of losing control. In this simulation, Chiaki played the role of his sister, doing it all for her own amusement.
His better nature didn't want to do anything immoral to her, but another part of him insisted that his third condition for completing this simulation was not conquering a dungeon, but rather indulging in carnal desires with various women, including his sister.
He took a deep breath, trying to regain control and push those thoughts aside.
Just as he was about to regain his composure, his sister forcefully pushed him back onto her bed once again with a mischievous grin on her face. It was evident that she found great amusement in witnessing her brother Nao's futile attempts to resist.
"Ah~"
She let out a surprised yelp as she felt Nao's hard cock as she sat on top of him. Seeing that situation becoming even more dire, Nao grabbed their right arm and tried to push her away.
"N-nee-chan... Stop!! it's getting out of the line..."
Despite his efforts, he can't move her. That was the first time he felt something wrong with his body. His body was totally out of control as if it was defying his intention and someone else controlling it.
He started to doubt if his sister also had a gift that was controlling him.
"Oh~, tell me Nao, what's the out of the line..."
When he heard his sister's seductive and amused voice Nao couldn't be more frustrated.
"N-nee-chan, stop immediately... or y-you will regret it..."
"What you gonna do?~ try to call our parents again?~"
He did his best to gather his strength and warn her to stop, but it only fueled her competitive nature even more. As he struggled to sit up, his sister's mischievous grin grew wider, a glimmer of amusement shining in her eyes.
In one swift movement, she reached for the edge of his shirt, her fingers playfully tracing along his skin. Her touch was teasing and sent a shiver down his spine, a mix of excitement and nervousness coursing through him.
Chiaki seemed to take great pleasure in touching Nao's body.
As his shirt came off, Nao's perfectly sculpted physique became more evident. His bare chest was exposed, his cheeks turning a deep shade of crimson. Despite his inner conflict, he couldn't help but be captivated by his sister's mischievous charm.
Her laughter filled the room, a melodic sound that echoed in his ears. Suddenly, she removed her undershirt, revealing her bare breasts to him.
With a mischievous smile on her face, she brought her face close to his and asked, "Is this your first time seeing a girl's breasts? How does it feel? Do you want to touch them?"
Chiaki's breath tickled his ear as she continued, "Nee-chan will teach you something in return... Do you want to learn?"
"Huh?!"
Without hesitation, she grabbed Nao's hand and placed it on her chest.
Nao experienced a momentary lapse in thought when he made contact with her chest.
In that instant, a surge of hormones - estrogen, testosterone, and progesterone - coursed through his body, causing his desires to intensify.
His arousal became so overwhelming that he momentarily forgot to even breathe. Nao's sister, Chiaki, had crossed a boundary that he had desperately clung to, plunging him into a sea of uncontrollable lust.
When he regained his senses, his breathing had steadied, and he no longer struggled against his desires.
"Mm?! Nao...?!"
Chiaki also noticed a profound transformation that occurred within him.
He had reached a point of surrender, where moral considerations and self-control no longer mattered. The distinction between reality and the world of adult entertainment ceased to be of importance.
The only thought that occupied his mind was the fear of losing his sense of masculinity if he were to retreat now. He released the inner beast that yearned to break free.
"...!!"
Before Chiaki realized what was happening, she was lying beneath her brother and his brother was looking directly into her eyes like a predator.
Everything happened within a fraction of a second, she couldn't even let out a surprised gasp but looked at her brother with bewildered eyes. Nao grabbed his sister's right hand which touched his body without any restraint and tried to retreat after noticing Nao's change of demeanor.
He forcefully placed her hands on his stomach muscles as if indicating to her to continue what she was doing a moment ago.
Nao held the back of her neck gently with both of his hands. Chiaki looked at her brother's lustful eyes blankly, at that moment she realized that she fucked up and shouldn't be teased him like that.
His cold eyes were sending a shiver all over her body with strange arousal. Her breathing got haggard, and her body started to tremble in excitement which she never experienced before.
His hand on the back of her neck sent a jolt of electricity through her body, igniting a fire within her that she had never experienced before. It was a strange mix of fear and arousal, a dangerous cocktail that both excited and terrified her.
Her heart pounded in her chest, the sound echoing in her ears as her breathing became ragged.
As Chiaki tried to process the sudden shift in her brother's behavior, her mind raced with a flurry of conflicting emotions. She had always known Nao to be protective and caring, but this side of him was entirely foreign and unsettling.
The intensity in his gaze made her feel vulnerable as if he could see right through her.
"N-Nao!!.. what are you go-Ah!!~"
Nao, unable to contain his overwhelming desire for Chiaki, impulsively leaned in and planted a passionate French kiss on her soft, inviting lips.
The intensity of the moment was so powerful that Chiaki's words were abruptly cut off, replaced by the electrifying sensation of their lips locked together in a fiery embrace.
