Maomi, an office lady, is a total pervert who gets excited by the smell of toilets. She masturbates in a park late at night, sticking her head in the toilet and sniffing it. She has sex in a multi-tenant building toilet while licking the toilet. When a man happens to come to relieve himself, Maomi begs him to let her drink his urine and enjoys drinking it. Her perversion continues at the internet cafe and in the company's kitchen.
