Hikari [Minamoto name: Miyabi] is a married woman who enters a soapland without telling her husband. Hikari, a quiet and unassuming person, started this business. Contrary to her appearance, her curiosity about sex and desire for pleasure grows. However, Hikari's normal course is not to kiss. It's not because I don't like her. I rather like her... But kissing ruins it. I'm afraid of myself losing her reason and drowning in pleasure too much.
