[MRSS-138] I Want A play With My Wife, But I Was Male Infertile, So I Had A Sperm Donor Cum Inside Me Ami Kiyo (Censored)

Because I was male infertile, I decided to use a sperm bank. Since I want to leave an excellent gene anyway, I asked Mr. Nagai, a super high-spec provider with an IQ of 141 and excellent motor nerves. However, Mr. Nagai says that he only provides the sperm by the timing method of 'providing sperm by actual sexual intercourse'. I think it's okay because I'm just saying that I'm going to have sex without love, but as a husband's servant, it's frustrating to be embraced by a man my wife doesn't know...!
