My husband is infertile due to mumps when he was a teenager. He also likes to watch me fuck other guys. "We" now have three children. We tell people we got sperm donors but not that the delivery mechanism was several days of fantastic fucking with a selection of thick-cocked lovers. We don't want any more kids but we still love bringing other men into our bed, especially if they are heavy cummers because I love feeling their semen spurting deep inside me.
I’m sorry about your husband infertility, but you surely found a much more enjoyable way to get sperm than going to a clinic!
I guess you made the most out of your situation and this is commendable. I assume it is only you fucking around, while your husband remains faithful…sounds like a very healthy relationship!
