A hot spring trip for two men and women, where they collide their bodies with lust and indulge in pleasure... Rie (pseudonym), 45 years old. "I can't stop masturbating while remembering my student's ejaculation..." The married woman, who was raised strictly in a family where both parents were teachers, married a match recommended by her parents. She continued her job as a music teacher until her child was born, but after that she became a full-time housewife. When her child-rearing settled down, she joined a local choir. There she reunited with a former student... and indulged in fantasies with someone who shared a certain secret. "I think it's a reaction to having lived seriously all this time... I just can't control myself anymore..." The married woman, who hasn't had sex for over 10 years, repeatedly climaxed while repeating "it feels good" when she was inserted with a penis that she desired.
