I Turned Into a Sexual Relief Maid

After losing his job, our protagonist is desperate. It’s then that he stumbles upon an offer that’s too good to be true: a well-paying live-in job at a rich girl’s mansion with no prior experience needed. He jumps at the occasion. Of course, if the job seems too good to be true, it’s because it is: he unwittingly gets genderbent and made to serve as the sexual relief for the horny futanari lady of the mansion. But surprisingly, she somehow doesn’t mind her new situation all that much.
