Drugless Sex
I've never seen a series be so faithful to the fact it is smut than this one. Every page is essentially smut that it's amazing. There's a couple of chapters that are a bit iffy because of the fetish displayed (where it's pedophilic even though they make sure the two don't have sex until they're a legal age...at least I hope). Other than that, they're all very cutesy plot settings with tons of smut scenes.

This is a poorly drawn story. It's more smut than anything else. Main lead has borderline stockholm syndrome and it's cringy at times.

Well, a piss fetish is probably one of the last things I expected to see in a yaoi/smut but here we are. Story is nearly non-existent but it is smut. The art style is nice and the redraws are very well done to the point where it feels like it was wasted on this story.
