A young wife, Akari Mitani, is impregnated with her pervert father-in-law's offspring in order to give birth to an heir.
I love my husband, but...I married into a prestigious family that has been going on for generations, and I tried to conceive with my husband to keep my blood flowing, but we couldn't conceive a child. My stepfather put me under anesthesia so that I could not move, then raped me and ejaculated inside me.
