After the husband disappears with his mistress and leaves a mountain of debt, a big-titted mother and her adult daughter are left with nowhere to turn. Their neighbor takes them in and lets them use his bath. Deeply grateful, the mother offers her body as thanks and lets him cum inside. Her adult daughter then insists on repaying him too, seducing him into sex that ends with another creampie. Their daily gratitude turns his dull life into a nonstop mother-and-daughter harem with Miu Arioka and Yunon Hoshimiya.
