The manga isn't doing a good job of explaining this since a lot of it was internal thinking, but apparently dominant alphas in this world like ML have an extra appendage that comes out of their junks while knotting. It keeps "attacking and licking the [omega's] innerwalls" when their junk gets so swollen it can't really move lol. So anytime MC is like, "WHAT IS THIS STRANGE FEELING" it is because there is something (he describes it like a spongy tongue) that makes him feel so good he is overwhelmed. ML knows about this but doesn't want to outright tell MC because he saw the appendage once and it was pretty ugly and he doesn't want to scare the MC. He is pretty self-conscious about it.
I see Mythoons actually did decide to join. Good grief it is getting to be borderline impossible to read and enjoy things on this site. If they are going to allow multiple uploaders they need to have tabs where the the chapters are or smth that sort by uploaders. Most popular uploader gets front tab. If there is no handle on this soon I am going to start looking for a different site to use.










I want to screenshot that "Let me devour you" panel because it is so funny and cute but I would literally die if anyone found that picture on my phone and asked what it was XP
