Kyoko, a young wife, is tired of raising children and due to the stress, she has less breast milk to give to her child. She was attacked by the intense pleasure of the aphrodisiac oil at a mammary gland beauty treatment just to get her milk flowing a little more, and she became addicted to the man's fingering. Everything would be over if her husband found out, but she even called a male masseuse to her home to receive a pleasurable massage and creampie sex.
