Mass confusion

Sumire and Makoto immediately began squirming in their seats. It was almost as if their asses had gone numb, and they weren't comfortable sitting on them. As if they were brand new to their bodies and they weren't used to them being there.

Makoto also leaned forward a bit, in the same fashion, it seemed like she wasn't used to the weight of her breasts. Sadayo followed suit, feeling this "new" unexpected weight on her chest.

Sadayo immediately grabbed her breasts.

"Wh-what happened?! Where did these come from?!" She exclaimed.

"I-I don't know! It happened to me too and... What's this thing above my legs?" Makoto grumbled.

"What do you mean? That's your butt. But these... Bags..?" Sadayo added, still groping her tits.

Sumire looked at Sadayo with confusion.

"Girls those are breasts but... Ms. Kawakami, what did you say this is?" Sumire asked, standing up and grabbing her ass.
