My father-in-law, who used to work and play vigorously until not long ago, has completely aged due to his injury. Tsubasa, the young wife, is worried about her father-in-law. One day, my father-in-law told me that I was not well due to erectile dysfunction, but I had longed after a long period of being naked with Tsubasa. Tsubasa oscillates between the desire to devote herself to her father-in-law and a sense of immorality towards her husband. My father-in-law's aggressive sexual approach, which I don’t mind pretending to enhance my erection, is quite ridiculous.
