One year into her marriage, Yuri and her husband have become sexless because of his busy schedule. To satisfy her desires, Yuri has been secretly watching cheating-themed adult videos. Looking for a change of pace, she calls over a junior from college—now working as a massage therapist—for an at-home massage. However, her junior didn’t come with the intention of giving just a massage… he had something else in mind. And soon, Yuri begins to feel a dangerous thrill, caught between a massage and the temptation of an affair… and she slowly starts enjoying it.
