Twenty-two-year-old Runa Tsukishiro claims 800 sexual partners around the world and says she has sex almost every day—including just before returning to Japan. She comes home specifically to make her porn debut and find out how professional Japanese performers compare. Despite all her experience, a veteran porn actor’s precise, relentless pounding overwhelms her. Once the cock is inside, she can only surrender to the pleasure, writhing and cumming again and again in a storm of orgasms that leaves even this self-proclaimed global sex expert impressed.
