hello! Soo the only sure-fire way I know of to get a lot of results is to go onto that sketchy website - nhentai with Hinata Hyuga tagged - and look for the ones labeled with a British flag. You'll have to sift through a lot of harem, cheating, and incest djs, though, because I don't know of a way to get only naruto/hinata results.
Rated E NaruHina Doujinshi
"Agetai Futari" by Satomi - What does Hinata want for her birthday present?
"The First..." by Shimoyake - Hinata's too shy, so Naruto comes up with a solution.
"PRESENT" by Fes - Although they're engaged, Naruto always faces away when it's time to sleep.
"Kitty Panic!" by Oretto - Naruto buys a present for Hinata, but it's not what either of them expected.
Check the author pages to find the other uploaded djs linked to their names! There's a lot more that I didn't put here.
