A dealer who works the Shinjuku club scene spots Mina, a spectacularly proportioned 21-year-old adult college student with enormous breasts and long legs. Tequila and drugs lower her inhibitions; after oral sex and a mouth shot in a private restroom, they head to a hotel for more intoxicated sex. Her miraculous breasts, tight pussy, titjob, and squirting lead to sex twice that night and once the next morning. On another day after class, he secretly invites a muscular junior man to join them. Mina likes the newcomer, and the evening becomes a threesome with alternating penetration, room-soaking squirts, delirious moans, and a facial from both men.
