[surface tremble (Minamo Ruri)] Rettou Idenshi wa...... Satsushobun...... desu | Inferior genes... are to be culled... ♡ (THE iDOLM@STER: Shiny Colors) [Aishi21]

A buxom, twintailed idol straddles the producer and guides a vibrator against herself, with sweat, trembling fingers, and filming turning her body into the centerpiece of a dominance game. Amana, Rinze, Kiriko, and Hana expand that premise into a crowded group encounter, surrounding the self-described masochistic producer with intimate poses, an imposing strap-on, piercings, prominent tattoos, and taunts about his chastity and public humiliation. The title’s promise to cull “inferior genes” gives their contempt an eerie, quasi-scientific veneer, leaving pleasure and humiliation tangled with the possibility that his enforced continence may become permanent.
