MRSS-154 I want to have a child with my wife, but since I'm infertile, we decided to have a sperm donor ejaculate inside her directly. Yuma Sano

Because I was infertile, I decided to use a sperm bank. Since I was going to do it anyway, I wanted to leave behind excellent genes, so I asked Otaki, a man with an IQ of 141 and exceptional athletic ability. However, Otaki only provides sperm through 'actual intercourse' using the timing method. Although he says it's just work-like sex without love, as her husband, I still feel bitter that my wife is being embraced by a stranger…!
