"I work at a decent company and I have a serious image, but I'm worried that I might lose sight of who I really am, so I decided to apply..." Mikuru is so lewd that she masturbates every day. When she gets good, she moans like a complete pervert! When the switch is flipped, she becomes a real slut! The contrast with her uptight job is heart-pounding! Her obscenely huge breasts are the best!
