After learning that he is infertile, a husband turns to a sperm bank so he and his wife can have a child. Wanting exceptional genes, he chooses Otaki, a gifted donor with an IQ of 141 and outstanding athletic ability. There is one catch: Otaki only donates through timed, direct intercourse. He insists the sex will be clinical and loveless, but the husband still cannot suppress the humiliation of watching an unfamiliar man take his wife and ejaculate inside her.
