Bit of a shorter read(and it's a comic), but Zipper by Dacad is a really emotional story. There is, like, two pages of nudity, but the first one only alludes to something happening, and the other is more logical as to why the character is nude, since they didn't really have much of a choice in the matter(nothing non-consensual, it's just the situation they were in).

It is on Dacads Bsky as well, but the formatting is a bit fucked because they posted the comic in sections and reposted a couple pages every now and then, so it's a bit of a mess there.
