Your mom stayed hot enough to be a model even after having you, but all that might change pretty soon. A vacation of too many fun, drunken nights together and the sexual tension boiled over as she fumbled your dick out of your shorts and let you pump away at her. You didn’t wear a condom and you were both so caught up in the moment that by the time she asked you to pull out you were already spurting thick gobs of potent cum across her cervix walls. Both of you swore it would never happen again, and went to bed, but as soon as you woke up with a drooling erection pressing against her ass it happened again. And again at the changing room. Something had changed, and the looks you gave each other weren’t like they used to be. They were the knowing looks of two lovers. Your mom’s career as a model is probably over now, but her career raising a string of her own children/grandchildren is just starting.
