Photoshoot och casting audition för min pervy styvpappa

My step-dad works for an erotic studio, and I typically do the makeup for his models. After a photoshoot he asks me if I would like to take a few pictures as a birthday present for myself. After realizing how natural I was at it, he asks me to do more and more. Eventually he tells me that I could easily be cast in some of the actual scenes they film. Of course, I have to audition first. Being that he is the only one left at the studio, he takes it upon himself to run me through a typical casting. Surprise, surprise, it ends up with his dick in my mouth, then my pussy, and eventually a giant load on my face.
