Milk Fetish: Milady's Endless Edging Ejaculation

Aoi is a futanari succubus raised by the wealthy Jinmyouji family with a singular goal: when a succubus masturbates and is prevented from climaxing in the last second, their bodies produce a precious gem. Sale of these gems is the source of Jinmyouji family’s wealth. Unfortunately for Aoi, this means she spends her days surrounded by hot futanari maids who tease and pleasure her, but always prevent her from ejaculating. This last until the day a certain Milky infiltrates the Jinmyouji mansion under the guise of a maid with a goal of making Aoi climax and releasing her from her eternal edging torture.
