While you sleep, Shina goes to class the next morning Tiny Misadventures, the Interactive text story chapter 5 by Calvitonks

You quickly conclude it's best to try as soon as she’s awake: she seemed to like having you squirming inside her, so there shouldn’t be any trouble, right? Anyway, with your next move decided, you close your eyes and go back to sleep.

The next morning, Shina wakes up to her alarm clock. Being the morning person she has always been, she immediately turns it off and heads into the bathroom. While cleaning herself up, she can’t help but toy with her left nipple a little: she couldn’t help it, her breast was filled once again with a tiny, just like…

“Hmm, Fluffy was a lot naughtier when I found him, but that might be just my first impressions… anyway, I feel that today is but the first playful day in many to come!” she spoke her thoughts out loud in a melancholic tone, before she buried the somber memories of her previous pet down, replacing them with the cheerful expectations of the amount of lewd fun her new pet will certainly provide to her.

She exited the apartment’s bathroom, heading to her private bedroom with nothing but a towel covering her: she was glad as always that her roommate either slept soundly or exited far earlier than her on weekdays, since it meant that she didn’t need to bring clothes to the fairly small quarter. 

Once she was clothed, she prepared her day’s breakfast, grabbed her backpack, and exited the building, starting her daily work at her high school.

“Oh my, you seem in quite high spirits, Shina! Mind telling me what happened?” asked her best friend, Yuzuha, when she approached her: the two tended to walk a little together before splitting up to go to different destinations each morning.

“Oh, Yuzuha! I couldn’t help it: yesterday I found a tiny, and I can’t wait to have fun with him after the classes are over.” Shina replied, smiling and blushing proudly at her friend.

“What? No way! You lucky girl! Let me guess: he is on one of your large boobies, right? Spoke Yuzuha, first in a surprised tone before shifting to a teasing one.

“Hmph, you know me too well, I wanted to surprise you with a reveal of it! Anyway, yeah, he is on one of them, safe and sound, while ready to stimulate me once the time is right.” Shina pouted a bit while replying, now blushing due to slight embarrassment due to how intimately her friend knew about her preferences: they might differ on how to treat tinies each might get their hand on, but their friendship was deep and true.

You open your eyes, awoken up to familiar sounds, as the chatter and noise of students filter in from outside your current “room”; she must be at school. This is further confirmed when, after feeling you stretching out a little, she whispers to you, saying:

“Oh, hello in there, little pet, I can feel you woke up. Sorry, but could you go back to sleep for now, or just stay relatively still, please? We're in the middle of a lesson, and I don't want to make a scene here! I promise I'll play with you after school, okay?”

Now, what are you going to do?
