Pressure from the company's product sales caused female employee Takahashi to come up with a very creative new business idea for high-end underwear. Accordingly, she thinks that in order for customers to care and believe in the quality of the product, she must prove it herself by going to each person's home and wearing underwear on their body for them to verify. Of course, to check, they inevitably have to touch some sensitive areas with their hands to know the quality of the product. However, checking is one thing, buying it or not is another. Even though she knows the product is very good, to convince them to spend money to buy it, she must meet the sexual needs of each customer.
