I don't usually think of my characters as having roles in the bedroom, it's more what feels appropriate for the scene at the time. So, you can definitely imagine it swapped and think of this as a one-off, lol.
I get it, art should always comes first. Plus it is your story and they are your characters, I'm just there to enjoy the ride LOL so whatever it is that you share with us, I embrace it with open arms <3 So that you for this treat!
