One day, I had two male friends kidnap and imprison my sister. Knowing it was incest, I ejaculated inside her uterus ten times and then forcibly injected 420ml of semen. To the terrified, unresisting sister, I continuously ejaculated and expanded her vagina, injecting a large amount of live sperm to ensure complete fertilization… yeah… I just wanted a child with my beloved sister...【Big Brother's Story】
