Encountered another game (Harem in Another World) with a character premise I thought was RIDICULOUSLY hot.
Imagine a nun side character, maybe in Begus, that has a confessional booth. Ryen can go into the booth and talk about "the sin of lust," describing gradually more intense sexual escapades. Each time the nun gets a little more aroused, at one confessional she starts sneakily masturbating, and eventually invites Ryen for a "private cleansing" which results in a CG.
