Twenty-year-old former idol and current college student Rino Sakurano returns for her second porn shoot determined to discover new kinds of sex. After a nervous but intensely pleasurable debut filled with squirting, she tries a series of firsts: sex with an older man, an intimate two-person sex tape with a porn actor, masturbating on camera, bondage with toy play, and a threesome. The threesome leaves the deepest impression as she sucks one cock while another pounds her from behind, making her mind go blank and her body convulse harder than ever. Even the older man's unusual attention to her fingers and feet surprises her in a good way. Rino ends the day convinced that leaving idol work for porn was the right path and that a life filled with sex is what excites her most.
