Fukuta Momo, Kashiwagi Konatsu, Kisaragi Yuno, Oohara Amu are employees of a bank. During a serious system error, many people came to complain, but while waiting for a solution, some men said unpleasant words to these beautiful female employees. The female employees tried to explain to the customers, but no one understood. Suffering from the anger of the customers, they came up with a bold idea to help the customers relieve their anger and satisfy their desires. They seduced customers right at the company, fucking each other from the meeting room to the reception room. Perhaps this is the best customer service, so the men no longer complained and were less stressed.
