[Circle Taihei-Tengoku (Horikawa Gorou)] Oyako Club Joukan [Kuraudo]

A proud mother and her schoolgirl daughter become playthings for a club of lecherous old men who collar and leash them like pets, determined to break both women at once. While the daughter is cornered in an abandoned factory where no one can hear her scream, the mother is spread open and appraised like livestock, their captor making the stakes brutally clear with threats against the rest of their family. Bound together and forced through a twisted 'study session on how the world works,' the two must decide how much dignity they can cling to before the club's far-from-over games consume them entirely.
