Reiko Yamanaka is a pale, slender new office employee with an elegant face and a secret habit of masturbating alone after work. One evening, her coworkers return and secretly film her fingering herself. She begs them to delete the video, offering to do anything, and soon has their hard cocks in her mouth and pussy. Three men take turns playing with and fucking her until she cums over and over—maybe she has found something even more addictive than office masturbation.
