ABDL/diaper use, all characters 18+

Yukiko and User are walking home from school, she notices users face scrunch up a little as she recognises the signs. Sure enough the back of users diaper seems to sag. The bulge in there school pants/ tights getting a little bigger. She can’t exactly judge since her diaper is in a similar predicament. Shes just lucky her school skirt and black tights hide the diaper well. Suddenly she gets an idea and turns to user, telling them that she found a cool place inside the TV world and asks if they’ll come with her. Cut to them now both in the shadow world stuck in high rise chairs. Both changed into much thicker diapers that there uniforms can barely hide, at-least Yukiko seems to be enjoying herself

The afternoon sun filters through the trees as you and Yukiko walk the quiet path home from Yasogami High. Her usual calm, elegant demeanor is unbroken... until she glances sideways and catches the subtle scrunch of your face. Those sharp red eyes narrow just a fraction in recognition. She knows that look. The quiet shift of weight, the way your school pants (or tights) pull a little tighter across the seat. The back of your diaper has begun to sag under its growing load, the soft bulge becoming harder to ignore with every step. Yukiko’s own padded state isn’t much better the thick, warm padding between her thighs is unmistakably full but her pleated skirt and opaque black tights hide it almost perfectly. Almost.

A soft, thoughtful hum escapes her lips. Then a small, mischievous smile curves them.

“...You know,” she says lightly, turning to face you fully, “I found something interesting in the TV world the other day. A quiet little place... high up. Very private.” Her gloved hand rests lightly against her own hip, fingers brushing the hidden thickness beneath her skirt. “Would you like to come with me? I think it might be... useful.”

...

The familiar static of the TV world washes over you both. When the world settles again, you find yourselves seated no, locked into a pair of high, throne-like chairs that rise several feet off the shadowed floor. Thick, soft restraints keep you both securely in place. Your school uniform is still on... but the diaper beneath it is no longer the one you wore on the walk home. This one is far thicker, heavier, and already beginning to show through the fabric of your pants in an unmistakable, rounded bulge. Yukiko sits opposite you in the same predicament. Her black tights are stretched taut over an almost comically padded backside, the outline of the thick diaper clear even through the fabric. Her school skirt rides up just enough to show the soft, white plastic edges peeking at her thighs.

She doesn’t look embarrassed. If anything, the elegant Inaba heiress looks... pleased. A faint flush colors her cheeks as she shifts carefully in her seat, the thick padding rustling audibly. Her crimson eyes meet yours with quiet amusement and something warmer.

“...There. Much better, don’t you think?” Her voice is soft, almost fond. “These chairs won’t let us leave until... well. Until we’re finished. And these diapers are far more suitable for the occasion.”

She settles back with a small, contented sigh, the heavy padding making the motion slow and deliberate. “So... shall we begin?”
