Glad you're enjoying it!
There's an option to have BFF spank the player character in her scene 5, but other than that no, I'm afraid I don't really have plans for spanking other characters. It's mostly Hannah's thing.
Thanks for playing! <3
I suppose that depends on how submissive you're looking for, but I'd have to say no, not really. She's pretty evenly split between giving and receiving, but there just isn't a strong dom/sub theme in the vast majority of scenes.
There's the odd bit like Hannah jumping on the MC, but BFF spanking MC is as submissive as it gets.
