Someone hit Rin with a growth ray

I'd still hit it.

Sensei loses all resolve against this attack.

and yet again, the adult tag is the greatest tag on danbooru. Sadly for Aoki-sensei, Rin had given up on him 5 years ago and was won over by Kuro. ... or not.

Grown up is fine, but this is a little excessive. Rin deserves better.

healthy rin

Very appealing, but her face lacks the mischievous look that Rin usually has.

Thing is KnJ Is a series with a high curve factor (do remember her mother was nicely stacked as well); though imagine Adult Mimi... heh.
