[Rebecca's lips are so soft even compared to Reid who has some nice plush lips of his own. It's not her first time kissing another girl or even her first time kissing Rebecca specifically. Memories of their time with the mistletoe bot creep into her memory as they stay close and she has to wonder why they didn't take even greater advantage of that situation. Clearly, they needed to make up for it now.
And where she should have been dreading Reid seeing this, she was just disappointed she hadn't heard him yet, so he could enjoy it too.]
