Who can become the uncle's daughter? A proud uncle's adopted, pure and slender sisters vie for his services. Kitaoka Karin, Shiraishi Momo, DASS-589

Momo and Karin, older and younger sisters, grew up in a wealthy family and were well-behaved. However, one day their parents suddenly died in an accident, and they were taken in by their uncle. Despite their nervousness, they encouraged each other and went to their uncle's house together. Their uncle seemed gentle, and Momo and Karin slept peacefully. However, they woke up the next day to find themselves naked and handcuffed, utterly shocked. A lewd smile appeared on their faces, and their uncle's hatred for their father resurfaced. From this day forward, they would compete to serve their uncle, deciding who truly loved him as his "daughter," and the loser would be driven homeless.
