Kana is a caring and kind person who works as a nurse at a nearby hospital. She worries about me, her neighbor, and looks after me like a younger brother. But after that incident, my life has been a rollercoaster ride, experiencing heaven and hell at the same time as I cum inside her vagina. When the doctor told me that my sperm was useless, I lost my sense of self, but Kana rescued me by seducing me, saying, "It's not all bad. I'll make you forget about the bad things..." and I became absorbed in impregnating her.
