Yukito has just begun his new job at a mysterious mansion on the outside of town. The pay is too good to be true, and all he has to do is service the needs of the women who live there... Every day the mistress of the house and her daughters try new fetishes that Yukito must perform. Every day he's called upon to perform incredible sexual acts with the residents of Mamiya Manor. Can he bear the pressure?

Protagonist Sawatari Yukito was looking for a summer part time job, when by chance he came across an advertisement in a job search magazine for a position with really nice wages. Upon quickly contacting the employer and learning that the position had yet to be filled, he applied without delay. The job was as a live-in servant at a mansion. His first day of work arrived. Upon arrival at the mansion deep in the mountains he was surprised by the size of the grounds and the palatial building itself… appropriate for the richest of the rich. The mansion’s beautiful mistress and her equally beautiful daughters came out to meet him. However, within that day his expectations turned to bewilderment and then despair. By the time he learned the reason behind the high wages he was being offered for a simple handyman’s job, it was too late… The work that awaited him was that of a “handyman” in name only. He joined several other servants at the beck and call of the mansion’s mistress, tasked with pleasing every perverted whim of her odd family. Servants both male and female were unable to escape the mansion, forced to continually take part the unending bizarre play of the family’s mad escapades. Will Yukito ever be able to escape the mansion alive, or….?!
