Yoka, who loves taking care of others and wants a job that makes people happy, is sent to the Ashida family for a one-night-two-day housekeeping service. The Ashida couple, who requested the service, are out of the house. The Ashida brothers, who are shut-ins in the midst of puberty, use their position as sons to toy with Yoka's body... 'At first, I thought it was just harmless mischief...' Yoka falls into a hell of orgasms as she is tormented by the escalating 'pranks' and lewd acts of the shut-in boys.
