P5: Sumire’s Feeding (Patreon)

Within her highchair Sumire writhed, trying to break free of the wooden tray locking her to the seat. Even if she could have gotten her diapered butt through the small opening between the back of the chair—which was highly unlikely given the stuffers Ren had decided to stuff into her double diaper to make it extra thick—the nylon straps were locked tight with a special mechanism.

“Why so eager to get out?” Ren asked coyly, clinking a spoon around in a glass jar of baby food.

“Ngh,” Sumire groaned, dropping her crinkly, extra thick rump back into the wooden seat, “Too full daddy…”

Ren laughed, bringing another spoonful up to Sumire’s closed mouth. He pressed it to her lips, smearing the mashed carrots across them before dropping a glob onto her onesie. The cold mashed food seeped through the thin onesie’s fabric.

“Ooooh, too bad we didn’t get a bib. We’ll have to go back and get one next time we go. In all fairness, I didn’t think you’d be such a messy baby that we’d need one.”

“That was your fault!” she protested, pressing her stomach against the wooden tray and inadvertently squishing her abdomen, “I’m too full and yooommph—!”

The baby girl’s tirade was halted by another heaping spoonful of the baby food, emptying the jar. “And that’s another one down!” Ren said excitedly, adding it to a pile with eight others before cracking another.

Sumire’s eyes nearly popped out of her head when she saw him reach for a jar of mashed bananas. While it might be her favorite flavor out of the various jars of easily digestible and bland mush, she had a hard time imagining stomaching another container of baby food.

Just the little bit of pressure against her stomach from her struggling had left Sumire’s tummy rumbling, her body hard at work preparing to make room for more food.

Ren brought another spoonful of food up and this time Sumire didn’t fight it, resigning herself as she opened her mouth to accept it because Ren was dead set on making her consume every last one. Another groan escaped the redhead's mouth, followed by a surprised “eek” and a rumbling fart that reverberated against the wooden seat of the highchair.

Ren smiled at the sound, finally taking a break from relentlessly shoveling food into Sumire’s mouth. “Maybe you are just a little too full… though by the sound of it, I don’t think I’ll have to wait long for that to be resolved.”

The redhead blushed, squirming in her seat while her stomach shifted, dropping through her body like a speeding subway. Her embarrassment was peaking, but it was mixed with a strange enjoyment. Ren was being all doting and playful, giving every ounce of attention he had to her.

Even with the oncoming feeling that she was about to uncontrollably fill her pants, Sumire was loving the treatment because Ren had so completely taken control. He was driving her further into babyishness with each spoonful of mushy infant food.

“I’m not…” Sumire said bashfully, turning her face from Ren’s. Another fart punctuated the statement, her body betraying its intentions despite her vocal protests.

“Not what, Summie-chan? Get out of that chair? Be able to keep your diaper clean much longer?”

Both of these things were unavoidably true for poor Sumire who was so quickly losing the battle for control. Her hands crept forward as if they had minds of their own, gripping the edge of the wooden tray. Sumire tensed, pulling her bulging belly over the length of the tray. Her face came close to Ren’s teasing smile while her rumbling diapered rump left the highchair’s seat.

“I’m not…” Sumire paused as she felt her body reach the point of no return and the first log of mess lined up to eject into her diaper.

“Say it.” Ren commanded.

“I’m not going to be able to hold it!” Sumire shouted, her flatulence giving way to a loud squelch as the weight of her first push dropped into her diaper’s seat, forcing it down toward the wooden chair.

Ren, still close to Sumire, seemed to revel in her straining face as she filled her pants, smiling even wider before giving her a little peck on the cheek. Her focus was so quickly pulled away from her body’s strain by the kiss. She was left gawking at Ren while her body pushed automatically, removing the need for her strain.

In a cruel twist of fate, he saw this as the perfect opportunity. Not to explain his choice to kiss her, but to deposit another spoonful in her mouth while she continued to deposit her own mush into her pants. Hesitantly Sumire closed her mouth, accepting the offering of food.

The sagging back of her diaper continued dropping lower with fetid weight until it pressed against the seat of Sumire’s highchair. The shell of the nappy flattened as the last automatic excretions piled into it. No longer able to withstand the strain of holding herself up, Sumire’s stiff grip relaxed and she allowed herself to slide back onto the packed, squishy diaper beneath her.

The heat of Sumire’s accident enveloped her while the gunk squished underneath her, conforming to the shape of her rump. She let out a deep sigh, a sense of tranquility overtaking her now that the pain in her stomach was gone.

“I think I need a change.” she said plainly, returning from her babyish mindset now that she’d filled her pants.

Ren looked at her quizzically, still holding one of the jars of baby food in his hand. “What do you mean?” he asked, scooping another glob of the mush. “We’ve still got another twenty jars.”

Sumire’s eyes went wide, realizing Ren wasn’t joking. Almost instantly she slipped back into little space, whining in appeal to Ren. “But Daddyyyyy~! I’m so messy!”

“Well, you'd better hope your diaper can hold more because I’m not letting you out until we finish every single jar."

She could see from his expression that there wasn’t an argument to be had. She resigned herself to forcibly swallowing another spoonful of mush. Sumire hoped her diaper would hold too because already her stomach was already gurgling again. What happened the last time she’d exceeded her diaper’s capacity and leaked was fresh on her mind, and her daddy was always eager to punish her.
