Due to male infertility, I decided to use a sperm bank. After all, I still want to leave behind an excellent gene, so I asked Mr. Kobayashi, a high-spec supplier with an IQ of 141 and excellent motor skills. However, Mr. Kobayashi said that he only provides sperm through a method he referred to as 'sperm donation through actual sexual intercourse'. I thought it was fine because I only mentioned that I would have sex without love, but as a servant to my husband, it's uncomfortable to be embraced by a man whom my wife does not know...!
