Kata Hayami is the superintendent at an apartment building where two busty and very horny housewives reside. Whenever the ladies are feeling particularly unsatisfied with their husbands, they call upon Kata for some personalized handy-work. Thinking he’s making mere service calls, Kata innocently arrives at the ladies’ apartments. But it doesn’t take long for Kata to catch on that it’s the ladies that require the maintenance. Fortunately for Kata, he’s got the right tools for the job.
