I asked my neighbor to conceive with his wife because he was infertile

Because I have male infertility, I decided to use a sperm bank. However, because I wanted to leave behind an excellent gene, I asked Mr. Nagai, a super high specs provider with an IQ of 141 and excellent motor nerves. But Mr Nagai says he only recommends this method when 'sperm delivery is through direct sexual intercourse'. I think that's okay because all I'm saying is that I'll make love without love, but being hugged by a man who doesn't know my wife is her husband's servant is so frustrating...!
