Brooke couldn't see what Mom was doing, with her back turned, so all her attention was focused on Ashley.  She leaned forward a little, with Ashley's encouraging response, tentatively letting her tongue trace the outline of Ashley's lips, not forcing anything, instead asking in her own way if Ashley was okay with more.  She tried not to be mad at Mike, and trying something new with Ashley was definitely helping, but she still couldn't help but be more than a little peeved, wondering what reason he'd give for leaving her in the lurch, and not even bothering to explain himself.
