Is she... is she lactating chocolate milk?

*finishes translation*

My god, she IS lactating chocolate milk!

There's no ambiguity. The kanji used here is "Mother's Milk." It literally says "cocoa mother's milk".

Gods of Gensokyo.

If only it was normal.... I think the "chocolate" milk really ruined this picture...
