PRED-759 Intense Father x Sister Brainwashing We are the new father-in-law's sex toys. Karin Kitaoka Yui Tenma

The older sister, Yui, is a caring person who does housework, and the younger sister, Karin, is quiet and easy to get carried away. The two lived comfortably with their mother's remarried father-in-law, a wealthy man. However, while my mother is in the hospital due to a chronic illness, nightmares occur... The once kind father-in-law's attitude suddenly changes, and he approaches the sisters with his lust exposed. The easily swayed younger sister cleverly guides her into sex. I can't have a strong older sister.
