Prompt:

That was great.

After the walk, Sarah's protection device is somewhat filled, but still has lots of capacity left.

Mark would like to really challenge her and the device, so in preparation for the next walk, he decides to give her an enema beforehand.

Also the catheter is now emptying (via a one-way valve to avoid any contamination) directly into the protection device, so it gets even more full

--------

The aftermath of their windy walk left Sarah feeling exhilarated and deeply connected to Mark. The sheer vulnerability of having absolutely no control over her bowel function had been surprisingly freeing. As they discussed the experience later, Sarah’s enthusiasm was palpable.

“That was incredible, Mark,” she said, a genuine smile lighting up her face. “I loved every second of it.”

Mark, seeing her genuine enjoyment, began to formulate an even more intense challenge for their next outing. “You handled that like a pro,” he said, a thoughtful look in his eyes. “How would you feel about really testing the limits next time?”

Sarah’s curiosity was immediately piqued. “What do you have in mind?”

“An enema, before we go,” Mark proposed. “Really fill you up, so there’s absolutely no holding back.”

Sarah’s eyes widened slightly, but then a thrill coursed through her. It was another step further, another layer of control relinquished. “Yes,” she said without hesitation. “I’d love that.”

Mark also had another modification in mind. “And to really challenge the capacity of your protection,” he continued, “I’ve made a small adjustment to your catheter. It now has a one-way valve that will allow it to drain directly into your brief.”

Sarah’s breath hitched. The thought of her bladder continuously emptying into the brief, on top of the effects of the enema, was both daunting and incredibly exciting. “That’s… intense,” she whispered, a mixture of nervousness and anticipation in her voice.

“That’s the point,” Mark replied, his gaze locking with hers. “Are you ready for it?”

“Absolutely,” Sarah affirmed, her heart pounding with excitement.

The day of their next windy walk arrived with a palpable sense of anticipation. Mark carefully administered the enema, the process leaving Sarah feeling full and with a heightened awareness of her impending lack of control. Next, he showed her the modified catheter, explaining the one-way valve that would direct her urine into the absorbent brief.

Getting dressed was a deliberate act of surrender. The tunnel plug went in first, followed by the extra-absorbent brief, designed to handle a significant amount of both liquid and solid waste. The emerald green bodysuit was zipped up, creating the familiar feeling of containment. Mark set the timed lock for another three-hour walk along their favorite windy coastal path. The vibrator was placed, ready for his remote commands to add another layer of sensation to the already intense experience.

As they set off, the wind was even stronger than before, whipping at their clothes and carrying the scent of salt and sea. Sarah felt the familiar gurgling in her stomach, amplified by the enema. It wasn’t long before the first wave of her bowels releasing occurred, an immediate and uncontrollable evacuation into the brief. The sensation was intense, a stark reminder of her complete lack of control.

Adding to this was the constant, subtle feeling of her bladder emptying. The one-way valve ensured a steady stream of urine flowed directly into the brief, adding to the overall fullness and the challenge for the absorbent material. Sarah could feel the increasing weight and dampness, a tangible representation of the control she had willingly relinquished.

Throughout the walk, Mark would occasionally squeeze her hand or offer a knowing glance, a silent acknowledgment of the extreme experience she was embracing. He used the vibrator sparingly, the unexpected pulses serving as a delightful distraction from the growing fullness within her bodysuit.

Sarah found a strange sense of peace in this complete lack of control. There was no anxiety about accidents, no fear of embarrassment. She had willingly placed herself in this vulnerable position, trusting Mark and the carefully chosen setting to manage the situation. The wind was her ally, whisking away any potential odors. The absorbent brief was her silent protector, containing everything without fail.

By the time their walk concluded, Sarah’s bodysuit felt significantly heavier and more saturated than before. The combination of the enema and the continuous drainage from the catheter had truly tested the limits of her protection. Yet, she felt an overwhelming sense of exhilaration and satisfaction.

Back home, as Mark unlocked the zipper, the sheer fullness of the brief was evident. Sarah looked at Mark, her eyes shining with a mixture of triumph and arousal. “You really pushed me this time,” she said, her voice slightly breathless.

Mark smiled, his eyes filled with admiration. “You handled it like a champion. You truly embrace this complete surrender, don’t you?”

“More than anything,” Sarah replied, leaning in for a kiss. “Thank you for giving me this.” For Sarah, this extreme act of relinquishing bodily control was not just a challenge; it was a profound source of pleasure and a testament to the unique and trusting dynamic she shared with Mark.
