MRSS-146 I wanted to have a child with my tall wife, but since I was infertile, I had to have a sperm donor give me a creampie Miku Misora

Since I was infertile, I decided to use a sperm bank. I wanted to leave behind some excellent genes, so I asked Mr. Kobayashi, a super high-spec donor with an IQ of 141 and excellent athletic ability. However, Mr. Kobayashi says that he only uses the timing method of donating sperm during actual sexual intercourse. Are you saying that it's just a loveless, labor-oriented sexual intercourse?
