MRSS-146 The sister-in-law wants to get pregnant because her husband is infertile.

Due to male infertility, I decided to use a sperm bank. After all, I still wanted 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 the 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...!
