Yu Okubo, a pale second-year adult junior-college student in a tight dress, comes to a porn audition hoping to experience professional performers' sexual technique. The sheltered bookworm says she has never even masturbated, but after shyly touching herself nude, a cock suddenly slides into her smooth, shaved pussy and pounds her fast. Though initially panicked, she succumbs to the pleasure, squirts repeatedly from fingering, then services two cocks with her mouth and pussy before climaxing so hard she nearly passes out.
