MRSS-138 I want to have a child with my wife, but since I am infertile, I had to have a sperm donor give me a creampie Ami Kiyo

Since I was infertile, I decided to use a sperm bank. - I wanted to leave behind some excellent genes, so I asked Mr. Nagai, a super high-spec donor with an IQ of 141 and excellent athletic ability. - However, Mr. Nagai says that he only uses the timing method of donating sperm during actual sexual intercourse. - I think it's okay because they say they're just having loveless and laborious sex, but as a husband, I still find it frustrating that my wife is being held by a man she doesn't know...!
