In this doujinshi, two female characters from the Kakegurui series, Jabami Yumeko and Saotome Meari, lose so hard at gambling (the central focus of the series) that they become something like sexual pets, available for use and for purchase. One of the two girls, Yumeko, is bought by (apparently) a classmates who likes her, so things go well, while the other girl (a fair-headed tsundere-like twintailed girl, yum) is grabbed by a group of hard-boiled students who don’t take no for an answer.
It looks like happy sex even for the twintails girl (yeah, oddly perhaps), and the drawings have a unique style, as if Inomaru kept on getting better and better over the years, it’s real eye candy
Thanks to Doujin-Moe for this release!
