I'll give a try to recommend something (plot+smut)
the kuroneko series is pretty good

back then I avoided this one, dunno I disliked the cover somehow BIG FAT mistake

hmmm opinions can be diffrent. it has a plot, not like in canis e.g. but still has.
no plot is something like this I would say

and I think when you can say the characters are annoying, it shows that the story not only has smut bec. you are able to dislike them.

come on! just bec. you dislike it. it doesnt mean it just smut.
btw. I read the whole series. I liked it but after finishing it I dont like it anymore bec. it only blames shingo in the end. to make the series short "they arte werecats, Shingo is constantly insecure of everything and Kagami acts like an asshole the entire manga.
The rest is smut." is not correct. you could almost tear every yaoi manga like this appart.

I'd love this story too ^^ I read all their series I also love the story between kagami brother too ٩(๑❛ᴗ❛๑)۶
If there omegaserve I was hope look for their baby ⁄(⁄ ⁄·⁄ω⁄·⁄ ⁄)⁄

*sigh when did I say it has a big deep plot??? I am just saying it has a good one and its not only smut (getting tired to say it).
the person asked for good smut yaoi and it is one (not like e.g. daydream nightmare or Aitsu no Daihonmei whats only shounen-ai)

lol I am routing for an extra where the lil boy is grown up and tries to snatch shingo away^^

You will never know what kagami will do if that happens
Since he super duper overprotective ε=ε=(ノ≧∇≦)ノ
