kana works as a kind and caring nurse at a nearby hospital. she looks after me, her neighbor, like a brother. but after that incident, i experienced both heaven and hell as i creampied her pussy over and over. my life became a rollercoaster. told by the doctor that my sperm was useless, i lost myself. kana rescued me, saying, "not everything is bad, let me help you forget the unpleasant things," and i became obsessed with impregnating her.
