You're a Tiny that is in a city called Mihito City, a little humanoid that is 1 inch tall that has been treated by society as anything ranging from annoying bugs to common snacks. You didn't remember anything about yourself, not even your own name. After navigate a school through a vent near where you awake and narrowly escaping death from many school girls, you finally reached outside, and managed to survive through the gym class and luckily not getting caught by any gym suit girls. Though you accidentally got in a vent that leads to the changing room while in desperate of hiding from the girls from outside, and of course due to being in the changing room, you also eventually got noticed and chased by the girls that are changing, which you managed to succeed in hiding in a clothing basket, despite it smells a bit, but it helps you block the smell of deodorant throughout the room.

As the footsteps faded away as they probably can't find you, you sighs in relief, thinking that it's over, now you just need to wait for most girls to leave this room, you can leave this place in one piece. Then about a few minutes later, the footsteps and the chatters getting less and less, thinking that it's time to leave, but suddenly you hear booming footsteps and it's getting louder as you know the owner of those footsteps is walking right towards here.

The piece of clothing you here hiding inside is being lifted up!

A massive flesh-colored wall appears before your eyes! It's slowly getting closer!

You noticed the incoming threat to your life, but couldn't escape in time!

You are... Caught inside... A girl's bra!

The girls don't seem to notice you yet!

Imai: Hey, Misuzun... Surprise health check!!

Ushijima: Geez! Mai!! Cut it oooout!!

Imai: Aww, come on Just a little won't hurt"

The Mai girl starts to grope the Misuzu girl's left breast, which is right where you're trapped in, despite thanks to only half of your body being trapped, so you're not really suffocating and losing fresh air, but the bad news is the bra that the Misuzu girl wears is too tight-fitting, you muster all your strength but still can't move a budge, leaving you at the unknowing mercy of Mai's groping, while Misuzu's face blushes slightly.

Imai: Uri uri

After a few gropes, Misuzu's breathing start to get a bit quicker for a second, then quickly returns to normal as Mai stops, while you yourself is getting dizzy due to your head being shaken a lot but still managed to stay alive just fine.

Ushijima: That tickles...! That REALLY tickles...!! Cut it out already!!

Imai: Heeey Stop resisting so much!

You brace yourself since you can see Mai's hand start to move Misuzu's left breast again, as she gropes and rubs the breast left and right, make your vision shaking even more and get more intense. The pressure of being smooshed in between Misuzu's breast and the tightness of her bra keeps squeezing you, makes you start to feel a bit hurt now.

Ushijima: Geez...

The groping only happens in a few seconds, quick but rough and intense, and when you're attempting to calm down, you can hear the sound of Mai start to get quicker as the excitement of teasing and fondling Misuzu is too great for her to stop, while Misuzu's breathing also start to get quicker due to she has a bad feeling.

Imai: Haah... whoa... I'm... getting really excited!!

Ushijima: ...Mai? Mai...? Wait! Stop! No moooooore!!

But Mai starts to grope Misuzu's left breast even faster, but still not hurting Misuzu, causing Misuzu to let out soft then quickly loud moans of pleasure, her face blushes even a deeper red.

Ushijima: Ahn... ahn!!

After a few more minutes, the Mai girl seems to stop groping, Misuzu's face keep blushing red but slowly back to normal as she calms down, but you don't know if she will continue to grope her friend Misuzu and eventually crushes you without noticing, or they will notice you in time, or maybe they won't, you don't really know. You just simply know that this is totally not your day. But at least...you still hope that...you will lucky enough and the best and most positive results will come to you.
