My first wife got knocked up by her coworker. Miscarriage.
She had lost her BC and due to doctor being on vacation and an insurance issue we had to wait more then a month.
It was a week before her appointment when it happened, he used a condom the first session, then I pulled it off him the 2nd round with him promising to pull out. My wife ended up riding him as I stood and fed her my cock, was about to nut when I heard him groan he was close, my wife was moaning around my cock in orgasm when I started to cum, to his credit he tried to get her off him, he unloaded up into her, she missed her period and the test confirmed she was knocked up.
If she didn’t end up PH that Saturday night then I’m sure he knocked her up Monday at work when he dumped two loads in her. Once before work then again at the off site storage, I listened in on parts of both times.
