MDS – Mash To Dosukebe Suru Hon [English], an hentai doujinshi parodying the Fate Grand Order game, by Blue_Gk
Mash (you know which girl? Cute, glasses, stockings, shy face) pays her master a night visit, and because she’s not the only perv, he had prepared a costume in case she came. And thus we have Mash, with a sort of animal girl costume (mainly long ears, a tail, and a slutty revealing outfit) providing quality oral and vaginal sex.
It’s good hentai, drawn well, not too censored, so I got some hopes it should please you guys
Thanks to NHNL Translations for this release!
