The Omnistore System

Chapter 147 Lewd thoughts (R-18)

Kevin, still smirking, pretended to be confused and asked, "Why?"

Riya, a bit hesitant but still masturbating, replied, "It's a bit inappropriate, don't you think?"

Kevin acted like he was pondering over her question and then, with a nod, he said, "Yeah, it is. Then can I do it while facing you?"

Riya got even more embarrassed at the thought of him masturbating while looking at her. "No, you can't. Go do it in the bathroom or somewhere else," she said with a flushed face.

As she said this, Kevin turned toward her, shocking her. She exclaimed, "What are you doing?" She tried to hide her breasts and vagina, but Kevin didn't make any effort to conceal his penis, which was now directly aimed at her. She looked at it and was even more shocked as it was now fully exposed and appeared larger.

Kevin smirked inwardly, noticing her gaze on his penis, and said, "Why would I? You go do it somewhere else. I'm going to do it here," as he continued stroking his penis while looking at her.

Riya, frustrated, couldn't find a response to his stubbornness and also couldn't let him win. She retorted, "Are you mad? We are brother and sister! How can you even show me your dick and masturbate while looking at me?"

"So what if we're brother and sister? And it's not like I'm thinking of you while masturbating," Kevin said, smirking as he continued to stroke his penis.

"But... but..." Riya struggled to find words, her shocked eyes fixed on his penis.

"sis, we don't have any ill thoughts toward each other, right? So why can't we do it together, or else you have some lewd thoughts about me?" Kevin teased with a smirk.

"Don't bullshit!" Riya blurted out upon hearing Kevin, her eyes finally leaving Kevin's penis and locking onto his smirking face with a blush.

"Then touch my penis if you don't have any lewd thoughts about me," Kevin said, still smirking.

"And how would that help me prove that?" she asked with an incredulous expression, wondering how touching his penis could possibly prove that she didn't have any lewd thoughts about him.

"It won't, but if I touch your vagina at the same time you touch my penis, I would know," Kevin said, smirking and looking between her thighs, or the thing hidden between them.

"No, it won't, and I would never let you touch my vagina," Riya said, now putting her hand from her breasts to hide her vagina, making it more secure from Kevin's gaze.

"Then don't, just don't stop me from masturbating," Kevin said, and he started stroking his penis again. He added with a pause, "Only if you don't have any vulgar thoughts about me."

"I don't!" Riya exclaimed.

"Yeah, I believe you," Kevin said in a nonchalant tone that didn't make it seem like he really believed her words.

This frustrated Riya, and with a grunt, she said, "Go touch it and see for yourself," raising her thighs to make space for his hand to go.

While extending her hand toward his penis, Kevin stopped her and said, "Wait, let's do it together on the count of three."

Riya didn't say anything and just waited, looking at his penis with complex thoughts. 'I shouldn't be doing this,' she thought.

While Kevin insisted on the countdown,

"One."

'It's so big... it looks disgusting.'

"Two."

'I can't be turned on by this.'

"Three."

'Or am I?' With this question in her mind, she grabbed Kevin's penis, and just as Kevin's hands touched her vagina, her body jolted. "Ahh," she moaned, her thighs then suddenly clenched his hands in response, making her moan.

With shock, she looked at Kevin, who was teasingly looking at her as she tried to explain herself. "No, it's not what you think," she stammered.

Kevin, smirking, gazed at her worried and embarrassed face and said, "Then what do you think it is?"

"It's...it's..." Riya couldn't find any words to refute it.

Kevin sighed and said, "I don't care, just let go of my dick..." His hand was still stuck between her thighs, and his penis was still between her unusually soft hands.

Riya, with surprise, looked at his penis in her hand and felt it pulse, and instead of letting it go, she tightened her grip a bit, surprising Kevin.

"What are you doing? Let it go," Kevin said, acting scared.

Riya shook her head, her gaze fixed on Kevin's penis as she said, "No, first believe me, I don't have any lewd thoughts about you." Her mind was in a jumble, and all her thoughts were focused on the situation.

"What the hell? What kind of blackmail is this... Let go of my penis, you, uh, bitch," Kevin said, trying to free his penis from his friend's grasp but being cautious not to hurt himself in the process.

"No, first say you believe I don't have any lewd thoughts toward you," Riya said, sounding a bit intense as her grip tightened around Kevin's penis.

"Argh," Kevin grunted, feeling the pressure, and said, "I believe you don't have any lewd thoughts about me. Now, please, let it go," Kevin pleaded, trying to free himself from her grip.

Riya loosened her grip a bit and looked at Kevin's scared face, asking, "Really?"

"Yeah... really," Kevin said with a forced smile.

Hearing this, Riya loosened her grip even more, and Kevin started to feel relieved. But then, suddenly, she tightened her hold again, shocking Kevin. He looked at her with confusion as she declared with determination, "No, you don't believe me."

"Fucking bitch," Kevin cursed under his breath as he found himself in a rather precarious situation for the sake of a little pleasure.

Taking a deep breath, he tried to reason, "Riya, please let me go... What if mom wakes up and sees you holding my penis? What do you think she'll think?"

"I don't care. Either believe completely that I don't have any lewd thoughts about you or just let us stay like this," she declared with a determined expression, stubbornness oozing from her words. She couldn't bring herself to admit that she might have lewd thoughts about her own little brother, even if it wasn't her intention.

But she couldn't deny the throbbing sensation in her hand, which was now making her tingle between her thighs. She found herself slowly stroking it to elicit more reactions from it.
