This is around the time that were Pierce figures out that Rose isn't a threat, and that she knows him somehow, so he's licking her to show he trusts her and likes her. ahaha...

And Rose can't help but feel a little aroused by this lick. lawl... she doesn't know how she should react, though, because, like others, she was taught that feeling that way towards an "animal" is wrong. Pierce's normal form is no problem, though (for her) since he looks a lot more like a human.

YES, IN TIME THERE WILL BE SEXUAL IMAGES OF HER WITH THIS FORM. LOL

Note/warning: do not mention your own love life, thank you.
