http://www.comicvine.com/bootleg-6/4000-182008/ looks like the 4 girls (not sure of names although I think the orange one is from Wendy?) just got out of an onsen/hot spring or something.

Wondering if anyone knows any other covers, or maybe pages within chapters, that show scenes of characters having baths or showers. Or if not in the middle of this, then before (about to get in) or after (just having got out).

The Milkmaid, Chocolate Milkmaid, and Peter is the Wolf comics have all had shower scenes, though no full sex scenes (quite) in any of those cases.

I'll go and read through Chocolate Milkmaid, I don't remember seeing a bath scene there... I'm not doubting what you're saying, I've just forgotten it and should just refresh my memory
