The staff of Maverick Vice Studio, an adult film production (do not call it a "porn studio" around Regina!) outlet established by actors dissatisfied with "mainstream" erotica production and intent on finding a new way to work, where the actors can enjoy it more in a less "work-like" environment. When they're not producing movies, they give the MST3K treatment to erotic ("lemon") fan fiction (essentially a critique in the form of a snarky commentary; if you've seen Mystery Science Theater 3000 or any Rifftrax commentary, this should instantly be familiar).
The cast from left to right and their off-camera roles:
Talitha Starr - The visual effects/editor/prop girl. That's a 50 gallon drum of Cards Against Humanity reference that she's sitting on.
Marcus Magnum - The chief cameraman
[THE MAIN RIFFERS:]
Regina Hildegard - The founder and writer/director (in costume for one project, it seems)
Leona Maxima - The location scout
Arsen Lupe - The co-writer and Regina's first hire (also in costume for a project)
