Director Aida Yumeno's popular series "Ultimate Subjective JOI" is back and more powerful than ever! This time, the focus is entirely on throbbing. For viewers who love masturbation and ejaculation more than sex, we take masturbation itself and turn you into a shameless, indecent, lewd pervert who throbs uncontrollably. Complete seven short segments each day, following the commands of a lewd slut. Save after each one, continue the next day, and do your best not to get a game over. Start a week of being looked down upon by a lewd slut and being trained into a pervert who orgasms with her nipples like a woman.
