Go to show her new body to Mahiru

"I've got to show Big Sis Mahiru." Hiyoko said with all the excitement of a child opening their presents on Christmas before running into her room and going to get some clothes to wear.

Hiyoko grabbed the kimono that she wore while at the Academy and a pair of clean underwear.

Hiyoko put on the panties on first and realised something, they were super small, it was almost impossible to pull it up past her thighs. Hiyoko put in all of her might to pull it up and got them into place.

When she looked at herself in the mirror, she could see that her panties were like a thong, the back had completely disappeared between her ass cheeks and the front was a tiny piece of fabric that was barely hiding anything.

Hiyoko then tried to put on her small bra but when she pulled it over her boobs, they just popped out.

"No, no, no." Hiyoko's problem began to dawn on her, all of the clothes she owned was designed for her child-like body, not her adult body.

Hiyoko held up the kimono up to her body to see how much it would cover. Even without wearing it, Hiyoko could see that her waist and chest were too big to fit and that was ignoring that the usually long legs of the kimono were only cover a portion of her thighs as if it were a skirt that someone in a low budget porn film would wear.

Hiyoko looked back at her reflection again and came to a realisation. "I look like an old pervert..." Hiyoko couldn't help but say as she stared at an older woman trying to wear children's underwear that would never fit.

This was a major issue, classes started in half an hour and she had nothing to wear, what could she do?
