P3: Leash Training (Patreon)

Yukari stood in the small entranceway of her and her partner's apartment, her black Mary Janes waiting for her to step into them, perfectly polished and picked out to go with the frilly satin dress daddy Minato had picked out for her. Her plastic diaper cover peaked out from below the much too short skirt, tinting the crotch of her gigantic ABDL diaper a bright fluorescent pink.

The outfit had been one of Minato’s favorites, especially to take Yukari out in. It was perfect for showing off what a big baby she was, the pacifier steadily bobbing in and out of her mouth as she suckled. It was an immediate indicator to most when they saw her face before the rest of her outfit, and she was rarely without it. That paci was her favorite comfort object.

Minato looked at her lovingly, obviously enjoying the view that awaited him in front of the door. He had one hand on the folded up stroller that remained next to the door at all times. His other hand had something dangling from it: a long rope with a stuffed cat at one end and a loop at the other.

This was new for Yukari as usually Minato just lifted her into the stroller and wheeled her out of the door. This time he’d given her a choice.

“Did you hear me Yuyu? Which do you want for our walk, the stroller or the new leash I got?”

Yukari glowered at the new article her partner had brought home. She couldn’t tell if that or the stroller would be worse: she’d have more control over what she could see and do but would be toddling. The diaper between her legs firmly assured her of that. She’d be toddling about, fully bow-legged in public while the lead connecting her to her daddy marked her as his.

Being in the stroller meanwhile was a familiar but still irritating helplessness. She’d have to watch the faces of strangers as they noticed that a grown woman was being pushed around with her diaper on full display, likely well-used by that point.

She didn’t like either option and her face must have shown it because Minato smirked. “I-I don’t like either,” Yukari said weakly, feeling something well up from her core. “I’m not a baby, I shouldn’t be in a stroller or a leash. I can walk on my own, I promise.”

“Not a baby?” Minato asked, his smirk widening. “I don’t think that’s true.”

That feeling of swelling in her chest heightened, becoming an overwhelming geyser of rebellion that escaped from her throat. “I’m not! I can walk on my own and if you ever let me I could use the potty like a big girl. You don’t need to spank me to make me listen and I can feed myself. I’m not a baby. I don’t need this diaper! I want my big girl panties back!”

The only thing the brunette was missing from her sudden tirade was an obstinate little stomp to prove her point.

She was breathing heavily while staring at Minato, a little breathless from the outburst. The dominant one in their relationship had remained still while his little one shouted her demands, but his smirk had slipped away.

The flat face he gave to the rest of the world meant something else to Yukari: she was about to be proven wrong, hopefully not through punishment. The last time she’d talked back like this there had been straps involved… and tickling till she peed herself. That was the last pair of big girl undies she’d tried.

“You want your panties back?” Minato said, “Do I need to remind you what happened last time?”

Yukari cringed, having hoped he’d bring that up later rather than sooner. “That’s because you were tickling me!” she objected.

“Big girls don’t pee themselves when tickled. Let’s see, there was also the time we went to a restaurant and you didn’t have a bib so you got food over that nice dress. How about the time you tried to use the big girl potty and didn’t pull down your pants? I clearly recall all your accidents I’ve discovered throughout the day where you didn’t even know you’d pooped your pants.” Minato crossed his arms, taking his hand off the stroller and binding the leash between them.

Yukari was speechless. Her mouth moved with phantom objections to these claims that she could not vocally produce. Daddy had hit her with rapid-fire reasonings which, worst of all, had all happened within the last few weeks.

This stubborn desire for adulthood was a weak attempt to break away anyway. She knew it well. Ever since he'd taken over her care from Mitsuru, she would sometimes do this. Even then Yukari loved being babied by Minato, it was that meager feeling of embarrassment as strangers passed by that kept her wishing to return to adulthood.

Apparently, her body was determined to help prove Minato’s point because the gentle ffffssssssshhhhhh of pee soaking into her diaper’s padding filled the silence that Yukari couldn’t. She locked her defeated gaze with his as the crotch of her nappy expanded to meet the plastic pants shell around her waist. Minato’s gaze never left Yukari’s, but the smirk returned and he uncrossed his arms.

“Sorry daddy,” Yukari said, “I didn’t mean to get angry.”

Minato stepped forward, placing a gentle hand on Yukari’s back. “It’s okay Yuyu.” he said reassuringly.

The brunette practically melted at his touch, falling into him and locking into an embrace while she continued flooding her padding. Her arms tightened around his midsection, a gesture meant to reassure the both of them of their connection.

When she pulled away she was a little surprised by the newly added weight around her shoulders. In one smooth motion Minato had pulled the leash backpack onto her back and with that little distance between them now he had the space to snap the front harness closed.

“Ready to go?” Minato asked.

Yukari nodded, toddling out the door with the lead trailing behind her. She thought that maybe it’d be fun to try and run just to see if Minato could keep the leash—and her—from escaping.
