Role-playing

You were going to get right to the figurative meat of the matter, selecting Role-Playing.

A list pops up of various roles for Cassie, and looking over them, it occurs to you that this is more like altering her personality entirely, than simply Role-Playing.-

-Pet play: in this format, Cassie will act just like any other dog, going on hands and knees, barking, playing, etc.

-Dominatrix: in this format, Cassie will be your harsh mistress. She won't hurt you (much), and if you request the remote, she will comply.

-Slut: Cassie will always be horny, no matter what time of day. You can further specify her to be a submissive slut, begging you for sex, or a dominant slut, taking the initiative in an aggressive manner.
