The Omnistore System

Venice remained close to their entwined bodies as Kevin began his rhythmic thrusting. Her hand, sticky with the mingled fluids from Kevin's penis, felt slick and warm against her skin. She felt a tinge of satisfaction as she observed the intimate dance between Kevin and Sia. Pulling her face away from their crotch, Venice's eyes took in the full view of Sia's ample buttocks, spread apart by Kevin's firm grip.

Kevin's hands held Sia's hips tightly, guiding her movements as he thrust upward from beneath her, each motion causing his penis to plunge deep inside her. Sia's body was sprawled across his, her breathing erratic, and her moans filling the room. Venice could see the stretch of Sia's vaginal walls accommodating Kevin's size.

As she watched, Venice's gaze drifted to Sia's spread anus, clearly visible with each powerful thrust. The sight sparked a mischievous glint in her eyes. She felt a rush of excitement and a hint of jealousy, wanting to participate more actively in their shared pleasure. She licked her finger, mixing her saliva with the slick fluids already coating her hand, enhancing the slippery sensation.

With deliberate slowness, Venice reached out and squeezed Sia's spread buttocks, her fingers digging into the soft flesh. Sia gasped at the unexpected touch, her body shivering in response. Venice's voice was low and teasing as she murmured, "Sia, your asshole looks so tempting..."

Hearing Venice's comment, Sia blushed deeply, embarrassment washing over her as she instinctively hugged Kevin's face, pressing it firmly into her breasts. Kevin's warm breath against her skin sent shivers down her spine. Meanwhile, Venice's hand continued to roam over Sia's buttocks, her touch light and teasing. "Has Kevin played with it before?" Venice asked, her tone curious and playful.

Sia, her face buried in Kevin's hair, shook her head. This admission made Venice's smile widen with delight. She traced her finger along the outer rim of Sia's anus, feeling the tight muscle contract under her touch. "Then I get to be the first to feel inside of your asshole, huh?" she murmured, her voice a blend of surprise and excitement.

Sia's breath hitched as she felt the delicate pressure of Venice's finger. Her eyes widened in shock and anticipation. The sensation was both foreign and thrilling, making her nerves tingle. Venice's finger continued to circle the sensitive area, applying just enough pressure to tease but not enough to penetrate.

Finally, with a slow, deliberate movement, Venice pushed her slender finger into Sia's anus. The intrusion was gentle yet insistent, causing Sia to gasp loudly. Her moans filled the room as she instinctively pushed Kevin's face deeper into her breasts, seeking both comfort and distraction from the overwhelming sensations. "Ahhhh, Venice, don't..." she pleaded, her voice a mix of desire and protest.

Venice looked at her with a teasing grin, enjoying the power she held over her friend. She continued to move her finger in and out, feeling the tightness give way slightly with each thrust. "You look so sexy like this, Sia," she whispered, her eyes locked onto Sia's flushed face.

"What, can't I have a bit of fun?" Venice asked with a mischievous smile, raising her other hand and slapping it down on Sia's already quivering buttocks, making them jiggle even more.

Kevin watched Sia's face as Venice's hand struck her butt. It was as if the air had caught in her throat as she tried to control the overwhelming sensation. Smirking, Kevin spread her buttocks wider to give Venice better access, encouraging her teasing. "I made her like this," he said proudly, relishing the moment.

Since Kevin had returned, he constantly sought Venice, turning her into something of a sex maniac. Despite her frequent claims of being tired from his daily ravaging, she never refused him when he whipped out his penis and entered her. She would adjust her position to receive him better, aiming to touch spots that intensified the pleasure. Between sessions, she had also started teasing him.

Kevin loved this new side of Venice and relished the fact that he had transformed her into such a pervert. He knew that with just a bit more persuasion, he could have her join in threesomes with Chloe or Amy. He was already planning to continue his threesomes with her and Sia from now on.

"I'm cumming…" Sia announced breathlessly, her vaginal walls clenching tightly around Kevin's thrusting penis. The intensity of the sensation made her whole body tremble, and her anus tightened reflexively, halting Venice's teasing finger. But Venice wasn't one to be easily deterred. With a mischievous glint in her eyes, she forced a second finger into Sia's taut, sensitive hole.

Sia gasped, her body arching in response. The sudden intrusion pushed her over the edge, and she released an orgasm more powerful than she had anticipated. Her moans grew louder, echoing through the room, a raw expression of the overwhelming pleasure that consumed her. Her body quivered, and her thighs shook as the waves of her climax rolled through her.

Kevin, not yet reaching his own climax, continued to thrust his hips, each movement driving his penis deeper into her. He increased the pace and force, intensifying the sensations coursing through Sia's body. Every thrust pushed her closer to the edge, prolonging the peak of her orgasm.

Venice, enjoying her role in Sia's ecstasy, kept her fingers moving in and out of Sia's tight anus. "Yeah, cum more… cum harder… cum by your anus," she whispered seductively, her voice low and enticing. She punctuated her words by smacking Sia's buttocks with her free hand, the sharp sound of the impact mingling with Sia's cries of pleasure. The repeated slaps left Sia's skin red and tingling, adding a hint of pain to the overwhelming pleasure.

Venice was still riding the waves of her orgasm when Kevin followed suit, intensifying her peak. His warm Yang Qi sprayed into her vagina, staining her walls and making them more sensitive.

As he came, Kevin continued thrusting his hips, unconsciously spreading her buttocks wider. He leaned in for a deep kiss, releasing the rest of his Yang Qi inside her, amplifying the sensation.
