Rin Suzune says, "I've only dated a masochistic guy once." Since then, she has secretly developed a sadistic Kokoro, and she's actually a genius slut! With an innocent smile, she plays with the guy, skillfully using her mouth and nipple stimulation to make him ejaculate in large quantities! She even goes so far as to play with his anus and urinate on him! She visits a masochistic guy in Tokyo late at night and keeps on playing with him until the morning comes!
