[Synopsis]

Ono Shunichi finds out that there is a "sexual service department" in his company.
He is completely captivated and on this day too he enjoys the lewd work of his senior employee Yui.
In the middle of that, he is questioned about his childhood friend Akane who works in the sexual service department and Shunichi is vague in his words.
Later, when he goes to the office, he bumps into Akane, who looks the same as she did back then.
As they chat, partly jokingly, he becomes more and more interested in her and asks her to be his next service.
Although she seems surprised, once the play begins, she fully demonstrates the lewd play she has cultivated up until now and he is soon brought to climax.
Shunichi then pours his rising sexual desire out on her voluptuous body...
