The new employee is lucky

Nene and Momo are my two seniors in the company. The director let me join the two sisters' group to learn more about the job. I work hard and get along well with everyone, so I am very loved by everyone in the company. Especially Nene and Momo, they loved me even more when they knew I was still a virgin. I didn't understand why until one day the two sisters invited me to go to a motel.
