Someone better point me to the best ass eater ლ(´ڡ`ლ)

I got you: https://www.mangago.me/read-manga/red_string_quests/

Hajun from Red Candy, Yiho from Onward (side couple). I make comments on everything I read and I specifically said that those two are the champions of ass eating. Especially Yiho. To quote myself “he eats ass like it’s a group on the food pyramid.” Enjoy, they’re both great stories!
