How to lactate while keeping flat chest ?

[Averose]

Hii~ guyss, I want my flat chest character to lactate while keeping his chest size. If i use transformation or lady evergreen piercing, the chest always go to B cup. Ingesting Wild melon blue egg while lactating wont reduce the size back to flat.

I just want my flat boyish character to lactate and keep his flat chest.

Is it possible ? If so how ?

breast fullness adds cup size, unfortunately

Sad : (
Is there any workaround ? Maybe something that reduce max milk capacity without losing lactating.
