All performers are adults. Natsuki lives alone with her father, and their neighbor Fujita has lusted after the beautiful young woman since she was younger. Her father trusts him, but Natsuki despises the way he leers at her. When her father leaves on a business trip, Fujita seizes the opportunity and uses a hypnosis app to forcibly rewrite her personality, declaring that she will become his personal slave maid. The baby-faced, big-breasted adult is coerced into serving as his titjob maid and sex toy.
