A newbie OL named Amaya Asahina starts working at her company when suddenly a waterworks technician visits her room. She's attacked by him out of nowhere, forced into passionate kisses and caresses that leave her helplessly aroused. To her surprise, she discovers that the technician is actually a woman! The following week, the same technician pays her another visit, starting off by aggressively penetrating her tight anal opening. At first, Amaya struggles against it but gradually begins to enjoy the intense pleasure. Eventually, she experiences an explosive orgasm through her ass—her M-side awakens under the brutal force and ecstasy. What follows is a hardcore lesbian scene where Amaya is repeatedly brought to climax through anal sex, eventually succumbing to lust and losing herself in the pleasures...
