A woman who is always reading a book sitting by the window. I fell in love with her, even putting aside her work. When I finally spoke to her, all I could do was ask her name. From there, Yuuki-san pulled me in...I fell into a deep swamp of pleasure. Contrary to her neat and clean impression, Yuuki was aggressive, lewd, and greedy. I was toyed with, erected and ejaculated at my command, like a loyal dog.
