SCPX-524 - I mistakenly had intercourse with her mother, thinking she was her girlfriend, suddenly and without warning!!

I thought she was shaking her hips more seductively than usual, so I inserted myself as a prank. It felt so good today, and I was so overwhelmed that I quickly ejaculated after inserting from behind... but it turned out I had intercourse with her mother by mistake!? I thought it was a hopeless situation with no excuse, but her mother, aroused by the incomplete quick sex, asked for a second round!! I didn't know her mother could be so erotic....
