My brother, who loves having sex with women, recently moved to Tokyo when his wife went on a business trip. He stayed at my sister's place because she suggested he use her empty room. When asked about why he came to Tokyo, he revealed that it was due to breaking up with his girlfriend because of sex and wanting to improve his skills by visiting a brothel. However, the desired hostess had already quit her job there, leaving him clueless. Feeling pressured by his brother's request, my sister reluctantly agreed to be his practice partner despite not being comfortable with the idea.
