The Omnistore System

Chapter 161 Tingly Cheeks and Forbidden Kisses (R-18)

“fuck…” Riya cursed while lying on top of Kevin, breathing heavily. Her thighs still tightly squeezing Kevin’s penis, which was oozing semen onto her thighs. Kevin looked at her with a smirk, and she blushed as they shared a moment of post-orgasmic reflection.

‘We… we kissed,’ she said to herself with shock, finally realizing the forbiddenness of what they had done. The taboo pleasure had transformed into guilt as she felt the sticky, hot liquid on her thighs and Kevin’s semi-hard penis trapped between them.

Before she could fully register it, Kevin’s lips were on hers again, and his tongue was playing with hers. At first, Riya responded out of surprise, but then her annoyance grew. She pushed him away and firmly said, “Stop kissing me.” saying his, she started to get up from him.

Kevin flashed a sly grin and, with a teasing tone, replied, “Why, my dear big sis, what’s wrong with a little kiss between brother and sister? It’s all in good fun!”

She stood up, pulling up her pajamas, still with the evidence of their activities between her thighs. With a mix of anger and embarrassment, she exclaimed, “You ask what’s wrong with kissing between us? It’s all wrong! There’s nothing right about a brother kissing her own sister… you psycho!”

She continued while walking towards the stairs, her cheeks flushed with anger. “Kissing me on the cheeks is one thing, but you’re taking it to a whole new level, Kevin! We have boundaries!”

Kevin chuckled and playfully quipped, “Well, boundaries are meant to be pushed, right? Keeps things exciting.”

Riya shot back with a fiery glare, “Exciting? Kevin, we’re not characters in one of your novels! This isn’t some steamy plotline.”

Kevin winked mischievously, “Who said it can’t be a real-life adventure? Come on, Sis, you know you secretly love my antics.”

Riya huffed, “Love might be a strong word. More like tolerate with an eye roll.”

Kevin shrugged, still grinning, “Tolerate, love, same thing. Now, let’s not make a big deal out of a little fun. It’s all in good spirits.”

Riya sighed, exasperated but unable to suppress a blush. “You’re impossible, Kevin.” As she walked down the stairs and Kevin asked. “Where are you going?”

“To clean the mess you made,” she said, sounding annoyed as she walked a bit funny with her pajama sticking to her thighs.

“Wait, let me come too,” Kevin said and got up.

“Only if you don’t pull any of your pervert acts,” she said, sounding hesitant. 𝑶𝚟𝓁xt.𝓒𝔬𝓂

Kevin nodded with a serious expression and, still naked, followed her into the bathroom. As she began to undress, his eyes were once again drawn to her captivating figure. He couldn’t help but fixate on the evidence of their recent activities, noticing the semen on her inner thighs and the slight dilation of her anus because of Kevin keeping it stretched. The atmosphere in the bathroom was heavy with unspoken emotions as they both grappled with the consequences of their actions.

Catching Kevin looking at her undressing herself, she sighed and said, “Kevin, you know this isn’t a normal thing to do between siblings. This is… well, it’s just taboo, disgusting, and weird.”

Kevin leaned in closer, his voice a low, sultry whisper as he teased, “All those things can be exciting, Riya. Besides, who better to explore these uncharted territories with than your dearest little brother? Like I said, everything’s good other than having sex, and you can consider it as practice for your future relationships, don’t you?”

‘I look cool right?’ he thought’d, smirking to himself but as he turned on the shower, and just as he was about to look like a suave movie star under the flowing water, reality hit, and he grimaced comically. “tdatdatdtatd” he sputtered as the cold water shocked him back to his goofy self.

Riya chuckled at his antics, adjusted the water temperature to something a bit warmer, and joined him in the shower. She placed a hand on his chest and leaned in close, saying, “You know, you might have a point. As long as we keep things platonic and not have sex, we do anything else.”

“Exactly, that’s what I’ve been saying!” Kevin grinned and, not missing a beat, gently grabbed her face and leaned in for a kiss. Riya closed her eyes, and their lips met in a moment of shared understanding.

They shared a brief but passionate kiss, and when they parted, Riya smiled at Kevin. She pressed her ample chest against his body and playfully remarked, “But only until you get a girlfriend.”

Kevin grinned and teased, “Well, in that case, I’ll just have to stay single.”

“You flirt.” Riya couldn’t help but chuckle and playfully nibbled on his chest, causing Kevin to wince in pain. He asked, “Why did you do that? I am gonna bite you too..” And leaned to her cheek.

Riya attempted to escape her brother’s playful revenge, but he was quick to seize her cheek and, rather than kissing it, he playfully sucked on her cute cheeks. It sent shivers down her spine, and she squirmed, chuckling softly. “What are you doing, you pervert? It’s so tingly…hahaha…stop it…”

Kevin paused, smiled at her, and then moved to her lips, beginning to suck and play with them as she had done with his earlier. Before long, their lips transitioned into exploring each other’s mouths, their tongues entwined in each other’s mouth turn by turn.

And before they knew it, they were already under the sheets, still locked in a passionate kiss, both of them naked, with Maria sleeping peacefully next to them.

The soft rustling of the sheets filled the room as they shifted to find a comfortable position. Riya straddled Kevin, her thighs rubbing against his, creating an electrifying friction that sent shivers down their spines. They were consumed by the intoxicating sensation of their bodies pressed together, sharing warmth, lust, and a deeper connection than they had ever known.

As they kissed, Riya couldn’t help but feel a mixture of emotions. Her heart raced with desire and excitement, but there was a persistent voice in the back of her mind warning her about the consequences of their actions.
