Depth of Submission: Mei's Training

With each passing moment, she felt more and more lost in the fantasy, her desire and lust causing her to tremble with excitement. As she continued to walk, she couldn't resist the urge to clench around the plug, feeling an intense burst of pleasure and pain that made her knees go weak.

Eventually, Mei arrived back home, exhausted but also satisfied. The experience of being out in public with the larger plug stuffed up her ass was exhilarating. She felt exposed and vulnerable, yet at the same time entirely invigorated by the idea of being controlled and objectified.

She knew that she had taken a step deeper into her submission, and she couldn't wait to see what other boundaries her partner would push with her.

In the afterglow of her experience, the scent of her own arousal still heavy in the air, Mei couldn't resist the urge to touch herself. She let her fingers roam over her body, exploring every inch as she indulged in her fantasies once again. The feeling of being controlled and dominated, of being a sexual object for her partner, consumed her, and she couldn't imagine ever going back to a more vanilla existence.

As she lay there, pleasuring herself, she couldn't help but wonder what her partner had in store for her next. There was no limit to the fantasies and desires that they could explore, no boundary that they couldn't cross. And as her own body writhed with pleasure, she knew that she would always be willing to do whatever it takes to please her partner and explore the depths of her own sexuality.

Eventually, Mei climaxed with a shuddering gasp, her body consumed with pleasure and desire. She felt completely owned by her partner, submissive to his every whim and desire. And as she drifted off to sleep, still feeling the echoes of pleasure pulsing through her body, she couldn't wait to see what new and exciting experience he had planned for her in the future. The possibilities were endless, and she was ready to push her limits and explore the darkest corners of her own sexuality.

Mei had been wearing her second largest plug for a while now, and her partner felt it was time for her to switch to the largest one. He knew it would be a challenge for her, but he was confident that she would be able to handle it, eventually. He took out the second largest plug, lubed up the largest one, and turned to Mei, who was lying on the bed, her large gravid belly pressing into the mattress.

"Are you ready for this, my slut?" he asked.

Mei nodded, apprehension etched on her face. The largest plug that Mei's partner had replaced her other plug with was designed to keep her anus open wide. It was an impressive sight to behold- long and thick with a tapered cone shape, the deep, dark black color contrasting with the pale skin of her ass.

Her partner grinned and slid the plug into her waiting anus. She let out a gasp as he pushed it in deeper, and it was clear that this plug was a struggle for her. He could see her belly heaving with each breath, her muscles tensing in pain and pleasure.

"How does it feel?" he asked, his voice dripping with sadistic glee. "It's... it's too much," she panted, trying to control her breathing.

Her partner chuckled. "That's what I like to hear, We don't want you to have an accident, do we?" he said, and Mei could feel the heat of humiliation spreading through her body. She wondered what was wrong with her, why she enjoyed this so much.

His hand came down with a resounding smack against her plump ass, the impact sending ripples of pleasure coursing through her body. The impact made her round butt jiggle, the enchanting sight accentuated by her artificial, gravid belly shifting in tandem. Mei's body served as a canvas for his dominance, each spank a vivid reminder of her place as a willing object of his darkest fantasies.

Her partner told her to leave the plug in for twenty minutes before he would remove it and put in a smaller one. Mei nodded, and he left her alone to endure the plug.

It was not an easy twenty minutes for Mei. The longer the plug remained inside her, the more Mei became aware of just how wide it was keeping her anus open. It was impossible to stay relaxed; the constant presence made her acutely aware of every move and shift in her body. The relentless pressure of the plug kept her sphincter perpetually distended, bulging outward in a constant reminder of her submission.

Her imagination painted a tantalizing picture of her backdoor, stretched to its maximum capacity, accommodating the demanding girth of the plug. The thought of her anus clenching onto the plug, desperately trying to maintain its grip, fueled her arousal to new heights. The sensation of being filled so fully, her walls pushed to the brink, made her skin tingle with anticipation.

When her partner came back into the room, he saw the agony on her face and decided it was time to train her to cum with the plug inserted. He reached for the vibrator and turned it on, pressing it against Mei's swollen and sensitive clit. Mei's protests quickly turned to moans of pleasure and submission as her partner played with her body, the sensations of the toy combined with the stretch of the plug overwhelming her every sense and sensation.

Her partner continued to play with her, slowly thrusting the plug in and out, savoring the sight of her anus bulging, its delicate ring stretched as an invitation, as he teased her clit with the vibrator. Mei's hips moved involuntarily as she rode the waves of pleasure coursing through her body, and her partner could feel her body starting to relax around the plug.

As Mei's moans increased in intensity, her partner knew that she was ready. Slowly, he removed the plug, inch by inch, until it finally slipped out of her stretched anus. Mei let out a gasp of relief as the pressure reduced, cumming hard and fast under the stimulation of the vibrator.

Her partner observed the aftermath of the monumental plug being extracted from her gaping anus, he couldn't help but be captivated by the visually stunning display before him. Mei's anus, no longer bound by societal constraints of what is considered "normal," had transformed into a mesmerizing spectacle.

Mei's once-tight opening now gaped wide open, bloated and swollen with an extraordinary size that defied expectations. It was a reflection of her insatiable appetite for exploration, a declaration of her commitment to pushing the boundaries of pleasure past normal limits.

Her partner, in a breathless whisper of undeniable admiration, praised Mei's extraordinary display, reveling in the explicit, objectifying detail. "Oh, Mei," he exhaled, overcome with raw desire. "Your anus is a masterpiece. It's so much larger, so obscenely stretched compared to any ordinary woman. The way it gapes, a visual feast of sensuality... I've sculpted it for my pleasure."

Mei's quivered as her partner's unabashed praise and explicit descriptions coursed through her. A myriad of emotions flooded her being, intertwining in a complex web of shame, arousal, and a surprising sense of pride.

Her partner inserted the smaller plug, she felt a sense of disappointment at the loss of the large plug that had filled her so completely. She was keenly aware of how small and inadequate the plug felt in comparison.

As she lay on the bed, her partner praised her for being a good slut, and Mei felt a rush of pleasure at his words. She knew she was a slut, and she knew she deserved everything that was being done to her. It was a dangerous thought, but one that she couldn't help but indulge in.

Mei's partner looked at her with an intense, smoldering gaze as she tried to adjust to the immense size of the plug. Her body quivered as she tried to make it fit, but it was apparent that the sheer magnitude of it was proving to be a challenge for her.

With each shallow breath and each trembling motion of her body, Mei's partner grew more aroused. The raw, vulnerable display of Mei's body as she pushed to take him in made him feel incredibly powerful.

His eyes widened with excitement as he watched her struggle to accommodate the enormous size of the plug, her anus puckering outwards in a desperate attempt to make room for it. He could feel his own cock growing hard at the sight, his desire for her overwhelming his senses.

Taking a deep breath, he leaned over and spread her butt cheeks apart, running his fingers over the puckered flesh of her anus. It was stretched tight around the mass of the plug, making it difficult for her to move and causing her to moan with each exertion. The sheer size of the plug was almost too much to accommodate, and watching her struggle only increased his desire.

He traced the outline of her anus with his fingers, relishing in the way Mei writhed and groaned beneath him. The feeling of her submission was intoxicating, and he couldn't resist the urge to press the plug deeper and deeper into her ass.

As he watched her body writhing with pleasure, he knew that he was taking her to the limits of her endurance. The girth of the plug was almost incomprehensible; the way it pushed Mei open made her partner feel like he had claimed her in an almost primal way. Mei moaned as the plug filled her to the brim, the sensation raw and intoxicating.

With her partner's hands holding her open, Mei was completely exposed to his lustful gaze. And as he watched her struggle, he knew that she was completely at his mercy, completely under his control.

"Come on, Mei," her partner's voice was firm, his gaze fixed on her. Mei's mind was consumed with the sensation of the massive plug stretching her open, but she couldn't ignore the wet, hairless, and empty feeling in her pussy. "God, it feels so intense," she said finally, her voice barely above a whisper. "My ass is so full and stretched, but my pussy feels empty."

"That's right, my insatiable slut," he growled, his voice thick with desire. "You're going to have to get used to this feeling, because I can't always fuck you. We must embrace the pleasure and torment these moments bring."

As she struggled to focus on the plug, Mei could feel her arousal growing with each passing moment. The wetness between her legs was a constant reminder of her own desire, the need to be used and dominated by her partner. Her partner noticed the hungry look in Mei's eyes and leaned down to whisper in her ear, "Focus on the plug, slut. You know how much it pleases me to see you take it." But Mei couldn't help the whimper that escaped her lips as she felt her pussy leaking, slick with desire and need.

Despite her intense arousal, Mei knew she had to focus on the task at hand. She pushed deeper and deeper with the plug, gasping as it filled her completely. But even as she took more and more, her mind was consumed with the emptiness in her pussy, the desperate need to be filled and used.

Mei's partner watched her, taking in every detail. He could see the desperation in her body, the way her nipples were hard and the way her pussy was slick and dripping with moisture. And he knew that she was completely at his mercy, a willing participant in his perverse desires.

She could feel the power radiating from her partner, the knowledge that she was completely submissive to his will sending shivers of pleasure down her spine. And even as she struggled to accommodate the massive plug, she couldn't ignore the growing hunger inside her, the need to be used and objectified in ways she never thought possible.

Mei's lip trembled as she tried to push past the pain, the sensation of the plug stretching her anus sending shivers of pleasure through her body. Her partner's eyes were locked on her, taking in every detail of her submission and powerlessness.

As she adjusted to the size of the plug, Mei could feel the weight of her swollen belly pressing against the bed. It was a raw, helpless feeling, a clear sign of her complete submission to her partner's will. The saline solution had distended her belly to the point of discomfort, forcing her to lay back and endure each passing moment.

The weight of her belly made it difficult to move and only added to the discomfort of the plug, but Mei's desire to please her partner kept her focused. As she struggled to accommodate the massive size, she could feel the pressure building inside her, the sensation raw and intoxicating.

But still she persisted, determined to show her partner that she could handle anything he gave her. She gritted her teeth, feeling the plug slowly become more bearable as her body adjusted to its size.

Finally, after what felt like hours, Mei let out a sigh of relief as her partner removed the plug. She could feel the emptiness inside her, the sense of loss that came with having something so big taken away. But she knew that it was only a temporary reprieve - soon enough, she would be back on her hands and knees, taking whatever her partner wanted to give her.

"Fuck, Mei," her partner smirked, their voice dripping with sadistic pleasure. "Can't believe you're still trying to take that massive plug. You're such a fucking submissive slut, struggling for my amusement."

Mei's face flushed with a mixture of shame and arousal, her voice barely a whisper. "I... I can't help it," she confessed, her breath hitching in the air. "It's... it's a constant reminder of my submission to you. It's so big, it separates my ass cheeks, and I can't even sit properly or wear tight clothes. But... but it turns me on too," she admitted, her voice trembling with desire.

Her partner's eyes gleamed with satisfaction, their voice filled with a dominating tone. "Good. That's exactly what I want," they replied, relishing in their power over her. "Your discomfort, your struggle, it's all part of your objectification. You exist solely for my pleasure, a vessel modified to fit my darkest desires."

As Mei's pussy continued to throb with anticipation and arousal, her partner's words only fueled the fire within her. The sensation of being so full, stretched, and utterly under their control consumed her, causing her juices to trickle down her thighs, an undeniable sign of her uncontrollable desire. In this raw and unfiltered power dynamic, Mei understood her purpose and knew that her submission would always bring her the overwhelming mix of shame and pleasure that she craved.

As Mei fought against the sensation of being stretched, her partner's indifference to her discomfort resonated deeply within her. It reinforced the nature of their relationship, where her well-being was secondary to his insatiable desires. Her belly, a physical manifestation of her transformation, served as a stark reminder that she was nothing more than an object, subject to his whims and fulfillments.

The sight of Mei's dripping pussy, a result of the overwhelming arousal brought on by her submission, only solidified her role as a plaything for her partner's pleasure. The intensity of her desire further fed the power dynamics that defined their relationship, cementing her place as a willing vessel for his every command and craving.

Despite the discomfort, Mei knew that she had to push herself to endure the training. She came to her partner every day, asking nicely for him to change out the plug for the smaller one when it became too much for her to handle. He complied with her request, but Mei knew that he was not going to stop until her ass was fully trained.

As she wore the plug for longer periods, Mei began to feel like she was becoming addicted to the sensation of being filled. She found herself thinking about it all the time, even when the largest plug wasn't inserted. The constant feeling of pressure on her sphincter was both frustrating and thrilling.

Mei's partner's eyes hungrily devoured her as he noticed the increased wetness between her thighs. He watched the slick moisture coat her inner folds, evidence of her uncontrollable desire, heightened by the sensation of being stretched by the enormous plug. With a voice dripping with dark pleasure, he couldn't help but comment on her body's response.

"Look at you, my submissive slut. The more that plug stretches you out, the wetter that pretty little pussy becomes. Your body craves the exquisite combination of pressure and pleasure, doesn't it? The sight of you, so dripping and needy, is a testament to the depths of your readiness to be taken and ravished."

Mei's partner decided to take things to a new level. While the biggest butt plug was still in her ass, he plunged his thick cock inside her pussy. With every thrust, the large plug inside her pressed deeper, giving Mei an intense feeling of fullness. She found herself overwhelmed with the intense pleasure, and finally gave into the climax. She had a squirting orgasm so hard that a thick jet flew out and hit the sheets.

When Mei realized what had happened, she felt embarrassed and ashamed. Her partner noticed her mood and questioned her about it.

"What's wrong?" he asked. "I squirted," she replied quietly, embarrassed and ashamed.

Her partner chuckled, "Don't be ashamed," he said softly. "It's a natural and beautiful thing. Besides, it just proves how sexy and irresistible your situation is to you."

Mei's partner reveled in the fact that she could let go and squirt with such intensity. The feeling of being able to make her release in such a way was a source of immense pride for him. He loved the sensation of being covered with her juices and the raw power of her climax.

She was coming to realize that her partner had no intention of stopping the training anytime soon. It seemed as though he was determined to stretch her ass to its limits and beyond. Mei couldn't help but feel a mixture of fear and excitement at the thought of what was to come.

As Mei laid there panting, she realized that she had fully accepted her role as a submissive slut. She knew that her partner would continue to train her ass, and that she would do anything to please him. The thought of being forced to wear the largest plug for days on end filled her with both dread and desire.

Mei stumbled into their bedroom, exhausted and relieved after a long day. The largest butt plug had been a constant source of discomfort, but she had managed to wear it all day without swapping it out for the smaller one. She craved her partner's validation and approval, knowing how pleased he was with her progress.

As she approached him, he looked up from his phone and gave her a nod, his eyes filled with pride and dominance. "I did it," she panted, the sensation of the plug still at the forefront of her mind. "I wore the largest plug all day without having to change it out."

He smiled, his eyes glinting with the pleasure of her submission. "Good girl," he said, patting her head in a patronizing gesture. "I knew you could do it."

But Mei's smile quickly faded as a thought crossed her mind. "But...what if I become incontinent?" she asked, her voice filled with hesitation and fear. "I don't want to lose control of my bowels."

Her partner chuckled, the sound barely concealing his dominant desire. "I don't care about that," he said, his eyes sparkling with a sadistic lust. "In fact, I think I would like it. For you to be completely reliant on me and the plug." He paused, his words laced with humiliation and degradation. "Imagine how easy it would be to fuck your ass, knowing that you can't even control your own bodily functions."

Mei's face flushed with a mixture of embarrassment and arousal at her partner's words. She couldn't deny the excitement that coursed through her body at the thought of being so utterly degraded. But at the same time, the thought of losing control was absolutely terrifying.

Despite her fear, Mei knew that she craved the sensation of being completely dominated by her partner. Her mind raced with erotic images of being filled to the point of incontinence, her body completely unable to resist his desires.
