Since I was male infertile, I decided to use a sperm bank. I wanted to leave excellent genes, so I chose Mr. Nagai, a high-spec donor with an IQ of 141 and exceptional athletic ability. However, Mr. Nagai only provides sperm through the "timing method" of actual sexual intercourse. Although he says it's just a mechanical act without love, as a husband, it still feels frustrating for my wife to be embraced by a man she doesn't know...!
