Ohyakudo Jouzu No Sanae-san [English], a splendid hentai doujinshi parodying the Touhou series, by Michiking (AKA Anmitsu Yomogitei)

Damn, that looked so GOOD! That’s Michiking for ya: shotacon, true, but drawn with godlike skill, and extremely arousing
Other than that, bah, it’s about a shota attracted to Sanae, she tries to resist but gives in to temptation eventually, etcetera. Enjoy, folks!

Thanks to KFC Scanlations for this new Michiking release! ^_^

–Update: it’s got a sequel, now: Anmitsu Touhou The After vol. 2.

There’s a lot more for you, see The list of Michiking’s works on Hentairules!
