Lust of the Apartment Wives (Ume Soft, MangaGamer)

In a small apartment complex… The sort that might exist anywhere…
Our protagonist is a grocery deliveryman whose polite demeanor and pleasant smile have made him a bit of celebrity around the complex.
But his smile is not as innocent as it seems… for this deliveryman has an ulterior motive–sampling some of these finely-aged apartment wives!
Kaori, who positively overflows with mature sexuality.
Ryoko, who while plain to look at, is possessed of a hidden lust bubbling underneath the surface.
And Mayumi, a woman still nursing her newborn child, with enough of a chest to make our hero weak.
Their husbands can no longer satisfy them, so now it’s up to you!
