[Synopsis]

Shunichi's motivation at work has risen and he has been selected as the top performer of the month.
Just as he was trying to relieve his accumulated fatigue, he receives a call from his boss.
Is it another work case?
He opens the door reluctantly and there he sees the boss being serviced by Akane...
"I'd like to introduce you to a perverted employee in the sexual service department."
While confused by the situation of his childhood friend having sex with his boss, he decides to meet the employee as he is told...
However, the one who shows up is a quiet and serious female employee, Kyoko Fujiwara.
From her usual appearance, she doesn't seem to be very sexually active, so he doubts what the boss says.
However, when she starts serving him in the office, his thoughts are quickly overturned and even Shunichi awakens to a new sexual fetish...
