I'm looking for hentai animation or manga or doujinshi when the story talk about a wife or a mother join a club when the wives or the mothers get gangbanged or raped exactly like a manga named Happy mommy Yuiko (Shiawase mama Yuiko):
and another manga named MILF Meat Market (Boniku Market):
Buying resources out of their own pockets, spending energy and effort, with almost no return so that everyone can enjoy the cultural and entertainment products of developed countries at almost zero cost walking in the dark to serve the light, they are real heroes
