Arinomama No, Ama No Ana De (“Straight From The Nun’s Hole”) [English], an hentai doujinshi parodying the Touhou series, by Diisuke (Circle Eden)
Hijiri Byakuren visits a funeral in a slutty dress, becomes the lover of the son of the deceased, has sex with him until they become a couple, the end. That’s super extra premium shallow pro ©®™. But it does the job ^^
Basically, check if the art suits your tastes, it should help if you tolerate thick censorship bars and love bakunyu hentai or heart-shaped irises, the rest is up to you =)
Thanks to whoever is behind this release!
By the same artist, I also share Oku-san No Oppai Ga Dekasugiru Noga Warui, the funny 1000-kai Iku Made Deraremasen and Anmask ~ Abakareru Honshou.
