Bokura no Kawaii Ningen-sama

Amane has taken a complete U-turn in his life, moving from Tokyo City back to the countryside after his grandmother left him her house. The night after moving in he decides to kill time by jerking off when two attractive and completely naked men suddenly appear before him! They turn out to be spirits that were sealed away in the house and are extremely curious when it comes to humans. And now they're both licking Amane all over...?! This is a love story of two doting spirits and a gullible idiot as they learn how to live together.
