Kailey doesn't know why her legs won't go up. It takes a while for her foggy brain to realize it's her dress that fits tightly around her thighs. She decides that she hates clothes at this point!
She feels slightly light headed for a moment before she realizes that Max is walking up the stairs with her in his arms. As soon as they're in the room he puts her down and pushes her against the wall, hiking up her dress as he did so.
How the fuck could she breathe in this shit he thinks. It's so fucking tight! He roughly turns her to face the wall and presses her face on the cold wall.
