MRSS-154 I want to have a play with my wife, but I'm infertile, so I decided to have a sperm donor ejaculate directly into me. Yuma Sano

Description

Since I was infertile, I decided to use a sperm bank. Since I wanted to leave behind some excellent genes, I asked a man named Otaki, who has super high specs, an IQ of 141 and outstanding athletic ability. However, Otaki only provides sperm through the timing method, which means 'actual intercourse to provide sperm.' Since he says he will provide loveless, mechanical intercourse, I think it's okay, but as a husband, I still feel frustrated that my wife will be embraced by a man I don't know...!
