She lets you in on her work world, and you decide to push boundary after boundary to "help" her. First, you tell you can help with camera angles. Then, you offer to help her operate the fuck machine. You can't believe it! You've convinced your stepmother to let you fuck her with a proxy cock, basically.
Of course, you know you need to figure out how to push further, more, until you're pushing your own, actual, throbbing cock into your own, actual stepmother! Under the guise of helping her, of course. For work. Because you're a fan of the genre. You know what viewers want to see, after all...
