Thanks to anonderp for purchasing and scanning the book for me.

Shame it's oral-only but oh well. By the way, this is not the same girl as the Mujin story "Imouto Lips" (that's Miku, this is Mayu), and it seems the author is planning more oral-based stories in the Imouto Lip series.

psicomenace: indeed, like sister control or the ane koi book. The next Tenma-based book should be nice as well with a bit of yuri threesome, some chubby sister incest and so on.

I think there are better stories by Yuzuki N Dash but this one is good enough so thanks a lot.

This one remind me of "Little sister lip" which I considers to be the best work by this author.

I wonder where will this one goes.
