I've been looking for these two manga forever:
https://e-hentai.org/g/1112967/0f50ca51ec/https://e-hentai.org/g/1112969/b8a6774a83/It's four stories about a girl who gets haunted by a "Fundoshi Youkai", and said youkai is now her only form of panties she can wear. The second half of the first book (pic related) and the first half of the second book have some nice ENF in them (personally I prefer the former). It's a bit H, but the youkai always takes the dude about to rape her out before the dude can actually stick his dick in the girl.
