Monster books that are not Lily Mayne’s

Monsters book that are not Lily Mayne

Hello I’m looking for books with monsters (I read all of Lily Mayne’s book and highly recommend them !)

What I’m looking for is human/monsters relationship. I want them to discover each other, their likes and vulnerability. Would love it if the monster was strong or powerful.

Like a high ranking monster (prince or else) falling in love with a nobody human.

One specificity that I liked in Lily Mayne’s book is the >!pussy that monsters!< >!seem!< >!to have.!< I love that they work like envelops for their dicks and give them so much pleasure. Even better if the monster does not know he can feel pleasure from it.
