Marina is a Japanese adult film actress famous for her prodigious J cup (DD cup in American measurements) natural breasts.
Matsushima was scouted from her OL (office lady) job by a talent scout for adult films. She has supposedly forsaken bras because they are essentially unavailable in her size in Japan. She has released many movies that focus on her immense breasts, and has done several breast fetish photobooks and videos as well, in the bondage genre. Her later performances depict her as the aggressor, dominating her male co-stars.
