Ririka declares herself a 'lesbian slave'! The most radical and controversial work in Vivian's history is here. Masochistic Ririka is attacked by Mao Hamasaki and Aoi Rena in a double attack with real improvisation! Insults, slapping, choking, peeing, toys, strap-on orgasm hell. No matter how many times she climaxes or collapses, the camera doesn't stop. The screams of a female continue to echo. It starts suddenly, and once it starts, it never ends. The ultimate non-stop and endless training where they clash in earnest, each turbulent scene is recorded completely uncut!
