So for the plot. Here's the idea I have. I work with a government organization that works with aliens and I've been working on a omnitrix that would allow the user to turn into any alien in there prime with a huge cock to be the best breeder of their race. So in my lab at home is were I would work on it. I had completed the prototype and was going to test it tomorrow when my gf snook into my lab and put it on. As she's been waiting to peg me and be the dominant partner but I never let her. So after she takes it what will happen will I be able to resist these alien cocks, or will I submit to them.
That's my idea. We could add feminize or male pregnancy for alien eggs if your into those or we keep it like the plot.
I'm open to any changes, if you don't like it we can remake the plot, or we can add to it
