MRSS-190 Sperm donation NTR Because I'm infertile, a high-educated handsome guy ended up cumming inside my wife... Kyo-Ren

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 Kitayama, who has an extremely high IQ of 141 and excellent athletic ability. However, Kitayama only uses the timing method, in which sperm is donated during actual sexual intercourse. I think it's okay since they say they're just having loveless and laborious sex, but as a husband, I still find it frustrating that my wife is being held by a man she doesn't know...!
