Unfortunately I cannot remember any specific details but I vaguely remember a Manga/Doujinshi where a loli enters the men's public bath (Not sure if she was with someone or went in alone) and being a curious/naïve girl ends up having sex. I have already found several similar to this (Naïve girl enters men's bath) but not the one I'm looking for, any help would be great I'm also interested in this topic so any/all recommendations would be great.
Thanks in Advance.
