Okay, so I got a few issues from this Breast Expansion Story Club comic. I liked the first and third issue, but the main character only undergoes breast expansion in the first one and then shrinks while someone else grows. I don't know if there's any in the last three issues.
I mostly got them because I've become a mild fan of SaburoX. It's cute and kind of clever, but there's barely any nudity and no sex in any of the issues I got.
