Tabenai No? Ookami-san

A human child, Tarou, is abandoned in the forest as a sacrifice for the wolfman, Ul, who lives in the depths of the nearby forest. Disappointed by the tiny and stringy sacrifice, Ul feeds him tasty meals, makes him clean clothes, and protects him from harm until he's fit to eat. Tarou wants nothing more than his dear Ul to devour him as intended when he finally grows up, but many seasons go by in this forest with just the two of them. A truly sweet and melancholy BL story!
