A plain and inconspicuous office lady is a carnivorous girl, so she just raped her and became obedient female

One day I found a sex video from an amateur submission site. Nogi, a plain and dull office lady in my department, shows the extremely vulgar appearance that she doesn't usually show. "Hey, Nogi-san. This is you, right?" From that day on, Nogi-san has been my sex slave. When you get tired of overtime, you can do whatever you want, such as having Nogi give him a blowjob, opening his pussy, or thrust his dick into him and making him sniff. I was supposed to be my only masturbation pet... but everyone knew it...
