A married woman who is addicted to drug-filled shrimp curling massage

Keiko, 27 years old...I've been married to my husband for five years, and I spend every day in a fixed cycle. The couple's affairs have finally come once a week, and once a month has been six months... and almost forgotten about their happiness as a woman. One day, Keiko becomes interested in a flyer for a business trip massage in her mailbox at home. When I asked them to use a special serum that has a rejuvenating effect, they were oils containing aphrodisiacs. Keiko ends up regularly going for a drug-infused massage without telling her husband.
