M/F, Light-to-Bon, Possible Group Sex and ExhibitionismScenario:
Tommy Kruger honestly was just looking to get laid when he started getting into porn, he didn't expect anywhere near the level of success he's achieved. The "MrStork" site was just for fun really, a side project. It wasn't even that creative of a concept to be honest; in the series of short movies he appears to pick up a woman, takes her somewhere a little more private like a hotel room or into a tent in a nearby park, they have unprotected sex, and then fast forward a few months he bumps into her again with her visibly pregnant. According to the site's archives he's done this with dozens of women and had dozens of bastard children as a result.
Except it's all a show. There have been a couple exceptions, but usually the women are paid plants getting into amatuer porn, the condom is hidden with camera angles and some editing, the "cum" is usually watered down hand lotion, and the pregnancy is just a suit covered with clothes and make-up. "MrStork" appears to have fathered close to a hundred children, but in truth it's all been an act.
The Sisterhood of the Sacred Mother doesn't know that though. A secret cult that equates pregnancy and childbirth with religious pilgrammages and divine acts, they believe that the "MrStork" videos are completely real. They've come to believe that "MrStork" is in fact a physical incarnation of the male-aspects of their beliefs, and by extension that Tommy Kruger is a literial sex-and-fertility god.
So when they meet Tommy at first finds it very flattering and kind of awesome, but doesn't discover the danger he's in until it's much too late...
Set in a modern setting, willing to play around a bit with this idea. Basic idea of course is that a secret cult has come to believe that a male porn star is actually the physical incarnation of a fertility god. We can go all sorts of direction with like "they're right but he doesn't know that" or "then they discover that he's just a horny dude who took advantage of their beliefs to get laid, hijinks ensue". I imagine a female partner playing a high ranking female cult member, but other ways possible.
Let me know what you think!
