牝犬発情記 ～かげりゆく日常～

あらすじ

Miyuki is a full-time housewife who spends her days waiting for her husband to come home from work. They used to be a happy newly-married couple, but their marriage has stagnated, they barely speak to each other and Miyuki is beginning to feel lonely. One day an acquaintance of her husband comes by, he is going on a long business trip and asks if Miyuki can take care of his dog while he is away, and Miyuki agrees to this. She now spends her days walking, feeding and bathing the dog, and it doesn't take long before the sexually starved Miyuki starts to take an interest in her new companion.
