When did I grow a huge pair of boobs...? Weird ol' alternate world.

That's an almost completely flat-chested Kyonko, actually. Look closer.

If you were referring to the chest of the girl she's grabbing, I'm pretty sure that's female Koizumi, and she always had some tit size.

I know. It was a joke :(

Probably a little too subtle.

No, not really. It's the point of view of this picture.
