Looking for an ecchi manga comic where the main character (a girl) is getting her boobs constantly bigger as some sort of revenge from a guy who obviously knows how to do that. I think its just a part of a bigger comic but it ends in a theatre where the girl stepps in to

In the end her boobs goes back to normal and the guy gets punished instead. I'm not really good at explaining but thats all i got.

Picture is unrelated btw.
