New employee Mizuki Aono is forced to share a hotel room with the department chief she despises during a business trip. Unaware that her drink has been spiked with an aphrodisiac, she is attacked in her sleep, and her hypersensitive body climaxes on its own as he creampies her. His sticky middle-aged techniques and the drugged sex scramble her mind. He keeps violating her until late at night, leaving her drooling, drenched in sweat and repeatedly making a blank orgasm face. As the pounding escalates and he fills her again and again, she gradually becomes addicted to her boss’s cock.
