The Omnistore System

Chapter 158 Stress reliever (R-18)

'Will she be okay?' Kevin pondered, lying beside Maria and observing her now-relieved expression as her fever subsided.

He didn't openly express it, but he was genuinely concerned about her. Despite not considering her his real mother, he cared deeply for her. She had shown him a genuine form of familial love, even if it was a bit unconventional. Initially, he found this love somewhat disgusting, but he had come to appreciate it. He hoped to experience a similar bond with his sister, who was fast asleep on his other side.

However, her breathing was too faint for a person who was asleep. So, he turned towards her, drew closer, and wrapped his arms around her waist, nestling up against her. This made her curl up, and she unintentionally pressed her soft behind against his crotch.

Riya found herself surprised by Kevin's hug, wondering, 'What is he doing?' He hadn't done this before, at least not until this morning.

Staying like that for a few minutes and noticing she wasn't objecting, Kevin took a relieved sigh inwardly and began to slide his hand beneath her clothes.

He wouldn't have had to do this if she had worn the clothes he bought for her. But earlier, she had purchased another night suit, this one with pajamas, which Kevin found to be a bit of a waste, as he can't see her muscular thighs in them. Nevertheless, he had to do it.

'He said it would be the last time.' Now, Riya's breathing had become more subdued as she felt Kevin's hands inching toward the waist of her pajamas. But just as they were about to enter, he paused.

Instead of going downward, his hands slipped into her shirt, exploring her muscular stomach, sending a slight shiver down her spine.

"Sis, you up?" Kevin asked out of nowhere, surprising Riya as she thought he was doing it because he assumed she was asleep.

"Mmmm," she made a sound with her eyes closed.

Kevin, seeing her reaction, smiled and with his hand still on her abs, he said, "You know, I was thinking about becoming a mathematician."

Riya found herself utterly flabbergasted by Kevin's proclamation. After all, he wasn't exactly known as the brightest bulb in the family, and his sudden ambition to become a mathematician left her thinking, 'Has he been sampling some weird herbs during his cultivation?' The notion of cultivators occasionally losing their marbles did cross her mind.

With a mixture of curiosity and skepticism, she asked, "Why?"

Kevin's grin widened mischievously as his hand continued its journey across her stomach. He replied, "Because I want to calculate the equations for these 'abs-olutely' mesmerizing curves." Chuckling at his own clever wordplay, he left Riya in a state of both confusion and irritation, unsure of how to respond to his ridiculous flirtatious attempt.

Kevin, still basking in his earlier flirtatious comment, decided to up the ante and ventured further, sliding his hand into her pajamas without much hesitation. This unexpected move caught Riya off guard once again, as she felt his hand brushing against her intimate area. Annoyed, she questioned, "What do you think you're doing?"

With a hint of confusion, Kevin replied, pretending like it was all perfectly normal, "I'm just providing stress relief services, sis. You know, the latest in unconventional therapy."

Riya couldn't help but chuckle at his absurdity. "Oh, really? Well, I guess I could use some unorthodox stress relief today. Carry on, Dr. Kevin!, do you think I would say this, you pervert asshole Pull it out?" Saying this she tried to pull his hand out of her pants, but wasn't able to. So, she couldn't help but react, her voice carrying a touch of anger, "I Said pull it out, I don't need any stress released therapy I'm fine, and how on earth can you reduce my stress by touching me there?" She asked, but this time didn't remove his hand, letting it linger at the top of her private area while she massaged her own stomach.

Kevin, showing no signs of backing down, pressed his playful argument further, "You see, you might not even realize you're stressed, but I've got a sixth sense for stress, Riya. Plus, don't fret, you don't have to reciprocate; I'm a self-sufficient stress-reliever."

He continued to explore her nether regions with a mischievous grin. Riya, feeling guilty making her emotions messed up, couldn't help but voice her concern with anger, "Kevin, isn't this a bit, you know, vulgar? Our mother is unwell, and here we are, indulging in some, well, 'stress relief' activities. You don't feel embarrassed, don't you?"

Kevin, undeterred by Riya's questions, continued his teasing exploration, his fingers gliding sensually along her folds, occasionally brushing against her clit. He tantalized her hole without fully penetrating, maintaining a mesmerizing rhythm of strokes. Simultaneously, his lips sought refuge on her neck, planting kisses that sent shivers down her spine.

Amidst the electrifying sensations, Riya managed to breathe out, "You... Kevin, you're absolutely shameless, aren't you?" In response, her own hands began to dance with desire as they moved to satisfy her needs in the midst of Kevin's audacious advances.

As Kevin continued to coax Riya into pressing closer to him, his lips took a brief respite from her neck. He chuckled, "Well, I'm not really doing anything wrong, just assisting my sister in relieving some stress – it's just my unique way, a tad...unorthodox."

Riya, her voice tinged with a mixture of guilt and pleasure, gasped out, "It's not just a bit unorthodox, it's downright taboo... taboo... ohhh." As she spoke, she felt the waves of guilt wash over her, only to be swept away by the addictive pleasure coursing through her body, a sensation she had never experienced before.

With a mischievous smirk, Kevin continued to tease Riya, his lips brushing against her ears as he whispered seductively, "And you... you like this, don't you?"

'I like it?' Riya pondered, caught in the whirlwind of sensations from Kevin's tongue and hands. Her mind raced, trying to make sense of it all, but the answer remained elusive. In the end, she could only muster a hesitant response, "I don't know..."

Kevin, momentarily distracted by the sensations, pulled his face away from Riya's neck, a bit lost in the heat of the moment. He asked, "You don't know what?"

Riya, with her desires aflame and her thoughts a jumbled mess, confessed, "I don't know if I like this or not..." She squeezed his hand firmly between her thighs, rubbing them together to intensify the sensations.

Kevin smirked and planted a light kiss on Riya's cheek. "Then let's find out tonight," he suggested, mirroring her own desire to explore this forbidden path with their friend.

Both of them believed that practical experience was the best way to determine their feelings about this taboo act. Riya, with the excuse of understanding her emotions, continued down this sinful road, secretly hoping to never truly figure it out, all the while convincing herself that it felt less wrong with each passing moment.
