Edit April 12: Thank you Lucine for the explanation about the nipple pee thingie. I have to admit I totally don't remember that detail. Gonna need to reread the manga again lol
Lovey dovey absolutely smutty with the bottom having some scruff on the chin
A+++
EDIT: TO EXPLAIN THE PEEING NIPPLE COMMENT
it's actually a canon issue the Kafka (yes that's our spikey-hair'd lead character's name) deals with after he gains the ability to transform into a Kaiju. He uh, now pees from his nipples. Kaiju biology, weeee?
