Sumeragi Renge

Wataru is a young man who moves into an apartment next to Tomoka and Fumie Fusono, two voluptuous sisters who used to know him when he was a shy child. Now Wataru is all grown up, and the Fusono sisters are ready to take full advantage of that fact.

Hayami Kouta 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 Kouta for some personalized handywork. Thinking he's making mere service calls, Kouta innocently arrives at the ladies' apartments. But it doesn't take long for Kouta to catch on that it's the ladies that require the maintenance. Fortunately for Kouta, he's got the right tools for the job.
