Riho is a young wife who dreamed of a happy marriage, but failed attempts to conceive have left her sexually frustrated. Wanting to look beautiful for her husband, she visits a spa where her innocence is exploited in a vile aphrodisiac training session. Oil raises her temperature and sensitivity until she can no longer resist the cock in front of her. Once she allows penetration, all restraint vanishes and she convulses through orgasm after orgasm. A filthy older man rubs his cock against her vaginal walls and repeatedly creampies her. She apologizes to her husband, but the heat in her womb will not subside; load after load from another man finally satisfies her desperate desire to conceive.
