START-448 The low-key bespectacled office junior is a frigid slut. After fooling around just once, she turned into a nympho and made me cum multiple times with techniques she'd saved up from erotic manga. Hoshino Riko

Hoshino is a plain-looking OL with glasses and unkempt bangs. One day during overtime, she developed a physical relationship with her playboy colleague whom she had feelings for. Hoshino was extremely shy about even showing her naked body, but after doing it once, she changed completely! Using techniques learned from the erotic manga I've been reading, I tormented and exhausted my colleague. The relationship where we switch between offense and defense is repeated in the office.
