The Omnistore System
Chapter 81 Backdoor Exploration (R-18)



After a moment of tasting, Maria released Kevin's finger from her mouth, her lips parting with a soft, wet sound. She licked her lips and looked into his eyes, a flush of embarrassment coloring her cheeks.

Kevin, with a sly grin, asked, "So, how did it taste?"

"It's... different," she admitted, her voice quivering slightly. "bit bitter and bit sweet, but also... intimate. I've never tasted anything like it." She hesitated for a moment before continuing, "But Kevin, are we really doing this? I mean, we're family, but this is..." She try her last act of being forced.

"We've already had come this far, Mom, So what if we explored you're backdoor a bit more" Kevin murmured, his voice thick with desire. "And don't act like you haven't experienced anything quite like this before with your anus. My penis is practically begging for a taste, so you better brace yourself." With determination, Kevin gazed down at her anus. He freed his hard member from his pants and positioned it right at the entrance of her backdoor. 

"Wait, aren't you going to lick it?" Maria asked, her surprise evident as she felt an unexpected warmth against her sensitive anal skin.

"Who said I was going to lick your dirty asshole?" Kevin replied with a smirk. "I just want to get a taste of it, and my penis is going to do the honors."

"No, I'm not ready for that yet," Maria hurriedly protested as she felt a persistent pressure against her tightly clenched opening, Kevin's member attempting to push its way inside.

But Kevin paid little heed to her resistance or the tightness of her anus. He was determined to stretch and breach it, even if it made her cry out and plead for him to stop. He wouldn't relent until the sensation of her soft buttocks pressing against his stomach was met with his full penetration into her backdoor.

Maria's eyes widened as Kevin's intentions became clear. The forbidden excitement that had been building within her now mingled with a growing sense of apprehension. She felt a mixture of anticipation and fear as Kevin persisted, his determination evident in his actions.

"Kevin, wait, not there..." Maria's voice wavered, her attempt to halt his advance met with resistance. The sensation was intense and unfamiliar, and she wasn't sure if she was ready for this new level of intimacy.

Kevin, however, seemed unwavering in his pursuit, driven by a desire that was rapidly spiraling beyond their initial exploration. The line between family and something more blurred with each passing moment, and Maria found herself caught between the exhilaration of the unknown and the unease of crossing a boundary she had never imagined.

As Kevin continued with his determined actions, Maria found herself in a whirlwind of sensations and emotions. Her initial reluctance and unease were now entangled with the overwhelming physical experiences unfolding before her.

Her voice, tinged with frustration, managed to break through the mounting pleasure. "You still made me taste it..."

Kevin, driven by excitement and a hint of mischief, used his hand to spread her tight anus further. With a forceful thrust, he penetrated deep into her backdoor. The intensity of the moment caused Maria's back to arch, her lips forming a perfect 'O' as she experienced a sensation that felt like it transcended the physical realm, sending her into uncharted territory.

Kevin's eyes were shut tightly as he felt the tight grip of her anus around his member. He spoke with a mix of sensuality and audacity as he got use to her tightness. "My penis is quite sensitive; it likes to know what it's about to savor before indulging. Can't you feel it has already savored your essence... see how deeply it's immersed in you..."

Kevin remained motionless, allowing his fully engorged member to replace its place within her back passage. As her tight anus molded around his penis, her body pressed tightly against his, their forms merging seamlessly. Her soft, pliant buttocks pressed firmly against his crotch.

Maria, whose breath had almost halted, found herself in a whirlwind of sensations she had never experienced before. Her son's substantial presence thrusting into a territory of pleasure she had never explored left her breathless. Slowly, she took a long, shuddering breath. Her eyes returned from their rolled-back position to a more conventional gaze.

Her breathing became heavy and labored as her chest heaved with each breath, her body locked in Kevin's grasp. Her anal muscles alternated between tightening and loosening around Kevin's penis, creating a rhythmic sensation as they clenched and released, gently coaxing his member in and out.

Maria, overwhelmed by the sensations coursing through her, suddenly found the strength to protest. "What are you doing, Kevin? Take it out this instant, you can't...," she said, attempting to push him away from her anus.

However, Kevin had other plans. He swiftly withdrew his penis until just the head remained inside, and then, with a determined thrust, he buried himself back inside her, evoking a similar reaction from her body. Her back arched, and she writhed in response to his actions, her arousal intensifying.

Kevin, maintaining his smirk, continued to apply pressure against her buttocks and leaned on her hands, further completing the jockey sex position. "You seem to be getting used to it," he observed provocatively. "Don't you? Mom"

Maria's internal monologue wrestled with her conflicting desires. Her heart raced as she yearned for something she couldn't fully admit to herself.

'Yes, Maria, you want this, but you can't just say it him like this,' she thought, battling her inner turmoil. Her eyes, shimmering with feigned tears, locked onto Kevin's, masking her true feelings behind a façade of pain.

Maria's internal monologue wrestled with her conflicting desires. Her heart raced as she yearned for something she couldn't fully admit to herself.

"No, Kevin, please," she whimpered, the words a feeble attempt to dissuade him. But her body betrayed her true desires, arching to meet his forceful thrusts even as her words begged for mercy.

Kevin, devoid of pity and consumed by desire, firmly gripped Maria's disheveled hair, tilting her head back so she couldn't look away. Her breasts, pressed against the floor, now had some room to move as Kevin's hips began to sway, slowly but forcefully. With each deliberate thrust, his crotch collided with her soft, jiggling butt.
