My first favourite was Trisha with the ass grinding, my second and current favourite is Mika... with everything to do with her ass. I would like more content with the 3 succubus campers, but more content with any girls is a win in my book.
I'd also like to see more "alien" girls, for example the tongues Amy has in her vagina is one of my more obscure fetishes I picked up from some erotica named "Taming the Succubus" (of which I can only find 1 of 3 parts atm, it used to be up on literotica)
