MRSS-148

Synopsis: Since I was infertile, I decided to use a sperm bank. I wanted to pass on my excellent genes, so I asked a man named Mitoma, who is handsome, has an IQ of 141, and is extremely athletic. However, Mitoma only uses the timing method of donating sperm through 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 to see my wife in the arms of a man she doesn't know...!
