Forced into complete submission as an immobilized, humiliated sex slave! Her body ensnared in a whirlwind of shame and pleasure, this beautiful woman descends endlessly into depravity! The secret group "Sweet Angels" was rumored to be making huge profits through compensated dating using methods rivaling the yakuza, yet its true nature remains shrouded in mystery. Led by Tsujimaru, the "Black Lion Society" has made it their mission to investigate and destroy the organization, capturing its members and suspects one by one, subjecting them to pleasure-based interrogations—cruel training sessions disguised as questioning—where danger and ecstasy continuously collide in an unrelenting assault.
