The Omnistore System

Chapter 146 Like mother, like daughter : Part 1 (R-18)

Riya shot him a disgusted look and said, "And you didn't stop me? Are you a pervert who enjoys watching his own sister masturbate?"

Kevin scratched his head, feigning embarrassment. "Hey, don't blame me. You were the one going at it right next to me, and I didn't stop you, so you could finish your... 'thing.' Besides, you looked frustrated, so I didn't want to interrupt."

Riya blushed even more, but Kevin didn't let her feel too embarrassed. He said, "If you want to continue... continue. I'll look away. And if you need any help, just let me know. I'm actually quite skilled at it..." And turn his back toward her and adding. "But do it a bit silent, would you? Don't wanna wake up mom."

Saying this, he turned his back to her, making her face turn as red as a tomato. She tried to say something but stammered, "I... I... don't..."

"I said, no worries! Carry on with your morning rituals. We're brother and sister, so catching each other in these 'private moments' is just another day in the life of siblings," Kevin said with a chuckle, still not turning back.

However, she realized it sooner than later that her horniness might be clouding her judgment. If she had heard herself convincing herself to masturbate with her little brother lying next to her and knowing she's doing it, she would never have believed it. With a determined tone, she declared, "I'm not going to do it."

"Good for me, I can sleep now," Kevin said, still smirking.

Riya blushed even more, but she hadn't put her shorts back on. As she looked at Kevin's back, she gulped. 'Is he really not going to look back?' she wondered.

'Can I really do it?'

'Should I do it?'

Many questions echoed in her mind. For some reason, she couldn't help but think about masturbating, even after being caught in the act.

'He said I can do it? He doesn't mind? But... he is my brother... how can I do it him knowing I am doing it....how embarrassing would it be?' Riya asked herself once more while her hand ventured between her thighs, and her second hand returned to her nipples, this time choosing the one she had earlier left untouched.

'If... ahh, it wasn't for... ahh, Natalie stopping... ahh, me from doing it with her... ahh, I wouldn't... ahh, be this horny...' she thought, her gaze fixed on Kevin's back, afraid he might turn around.

While Kevin wore a grin from ear to ear, he couldn't help but notice the squishy sounds her hand was making as it ventured into her nether regions. Her breathing was also becoming increasingly audible. 'She's just like mom,' he thought, drawing a somewhat amusing comparison between the two ladies in his life. Despite the feeling that what they were doing was wrong on multiple levels, it seemed that both of them didn't care when it's a matter of carnal pleasure.

Now, Kevin had a mischievous plan in mind: he wanted to plant more provocative thoughts in Riya's head, all in the pursuit of pleasure. He found the perfect way to do it. Lying there in nothing but his shorts, he boldly grabbed his erect member and pulled it out.

Riya's eyes, which had been fixed on him, froze in their tracks as she watched in astonishment. What he revealed was truly impressive, and she was taken aback by the sheer size of it.

Riya's eyes widened like she had just stumbled upon a rare archaeological artifact, except this one was much more... erect. It was her first time witnessing a real-life, unsheathed sword of manhood, and boy, was she surprised. She'd watched her fair share of adult content, but this was the first time the action was happening live, and she wasn't quite sure how to react. She had some experience with dildos, but they paled in comparison to the size of her brother's member.

She swallowed hard, trying to control her emotions as a realization struck her. 'Wait, why did he take it out? Is he... he's stroking it!' Riya's mind raced as she observed her little brother joining in on the act.

Riya muttered to herself with annoyance, 'Why couldn't he wait until after I had my turn?' She couldn't help but feel a bit miffed that her private performance had been upstaged by Kevin's unexpected solo act.

She tried to ignore Kevin's presence, closing her eyes and focusing on her own fantasies. She imagined moments with her girlfriend, picturing their intimate encounters and the usual vanilla activities they enjoyed. But to her surprise, in the midst of her imaginative reverie, her brother's massive penis seemed to intrude into her mental scenery, making for a rather unexpected mental twist.

'shit.' Frustrated and annoyed by her own thoughts, she increased the pace of her movements. Opening her eyes, she muttered to herself, 'fuck... Why am I even imagining dicks? I like girls!' She cast an angry glance at Kevin's penis, with only its head visible in her view, blaming him for the unexpected turn of her thoughts. 'it's all because of him...'

She couldn't help but keep her gaze on Kevin as he continued stroking his penis, her own arousal growing with each passing moment. 'Why is he doing this now? Could it be because he saw me doing it? No, that can't be... we're siblings.' Riya's mind raced with conflicting thoughts as she kept pleasuring herself, all while sneaking glances at Kevin doing the same.

'But... ahhh, his penis is so big... ahh, He is gonna cum doing this right?....I never seen a man cum in real life..they are suppose to shot it that white stuff really far...he is gonna shot at...mom...' she thought, her eyes widening as she saw Kevin's penis brushing against Maria's back. With shock, she contemplated, 'No, he wouldn't dare to...or he is aroused by her?'

With her thoughts all jumbled and her arousal mounting, Riya couldn't bring herself to stop masturbating. 'I don't know if it's because of her or me, but I can't let him masturbate while looking at our mom,' she mumbled to herself. Finally, with a mix of embarrassment and determination, she spoke up, "I know you're masturbating... and I'm not stopping you, but could you not do it while looking at her?"
