An average guy is bestowed with the power to possess others' bodies via a smartphone app.
His classmate Miki gets mad at him because she sees him ogling her friend Alisa's breasts. To get back at Miki, he uses the app's new feature, scheduled possession, to take over Miki's body. He does lewd things with her body and records it using her cell phone. He experiences the sensation of peeing and uses her body to his heart's content.
He also possesses the big-breasted Alisa, but despite her mild-mannered personality, by night she's a bunny girl in a nightclub. Her job is to satisfy men's sexual desires! What happens next?!
