DANDY-676 — "My Younger Sister, A High School Student, Washes My Back For A Cheap Fee Under The Pretext Of A Part-Time Job. When I Set Up The Additional Option, My Bathroom At Home Became A Sex Shop With A Close Contact Bubble Body Wash And Real Sex." Vol.1

My younger sister, a high school student, begs me for pocket money since she lives at home. I'm worried about her future if I give her pocket money so easily, so I have her wash my back as a part-time job. At first, she may have resisted, but she gradually got used to it and the optional services became more and more abundant. That in itself makes me worried about my sister's future lol
