The first of two exclusive works by Mina Kitano, who captivates with her elegant beauty, style, and passionate play style! Mina is a career woman who is very strict about her work, and her only hobby is to train and develop men's anal holes and make them orgasm in the office, where they cannot make a sound. This time, she sets her sights on a timid male employee who joined the company as a mid-career hire but was not good at his job, and slowly develops him into the toy she likes.
