That JAV

Because of my male infertility, I decided to use a sperm bank. I wanted to leave behind excellent genes, so I asked Mr. Nagai, a very high-spec sperm donor with an IQ of 141 and excellent athleticism, to donate his sperm. However, Mr. Nagai said that he only uses the "timing method," in which sperm is donated through actual intercourse. I think it's safe to say that he says that he only performs loveless and work-like intercourse, but as a husband, I still feel frustrated that my wife is being held by a man I don't know...!
