My darling wife Chihiro was stricken with a sickness that had no treatment, except one: the creampie ejaculations up her beloved vagina by someone other than me, Shiro, her husband.

I wasn't a compatible donor. She needed the hot spunk of someone else, or she would die.
It was for her life. A pleasure prison, a violent fear. These were our hellish days...
