A/N: TPOV
Tonks' eyes scanned the titles listed, but she wasn't actually reading a single one. Instead she was focused on the rustle of paper she heard behind her, the rush of leather from the chair as the one who was sitting in it stood, the soft footfalls behind her, the unmistakable buzz of energy as he got close enough behind her for his aura to touch hers.
"I locked the door; you need not speak up about it if you do not wish to. I would like to take your mind off of such matters, if you would allow me, Nymphadora."
Tonks was still recovering from the red not fury that had turned into an icy emptiness. She wanted to scream, she wanted to cry, she wanted to lean back into Severus and listen to his voice telling her it would be alright for the rest of eternity. In the end all she could manage was a brief nod, still trying to hold everything back. Before she could do anything else she felt his hand fisting in her hair and pulling her back. A gasp escaped her lips as she was pulled back into his arms. Merlin I need this. She thought, the sharp pain helping dull her anger as his embrace helped thaw out the ice that had begun to form around the edges of her heart.
"I promise to do all that I can to make you feel safe, wanted, and desired. I am willing to do this as your Dominant, to take away the burdens of your life, no matter how temporarily, so that you can be happy. Even if for only mere moments. I will be here for you."
Tonks wanted nothing more than to embrace him in return for saying those words. As much as she thought she needed the pain and embrace, she realized that she had been wrong. This is what she had needed. She needed to be told that regardless of everything one person, one singular person was willing to be there for her no matter what. Before she could respond he spun her around and pinned her against the bookcase, a stack of books falling on their side in complaint. Her eyes were slightly unfocused as she looked up into his face, surprised at the amount of emotion and passion she saw there. She couldn't remember a time when she had seen him so unguarded.
"I wish to take you in so many ways, and to have you serve me in ways that you've only dreamed of in your most wicked fantasies. Such frank and open honesty from me is something that few ever get to see, but is the one thing that I can offer you as your Dominant."
Her lips parted slightly at what he described and her attention was divided between what his lips had to say and how close they were. In that moment she could only see him, only think about him. Answering his unasked questions, her body pulled futilely against the bonds created by his hands as her head thrust forward and eliminated the distance between them. Her lips found his and she immediately adored the spicy taste of him, marked with a hint of brandy. A slight moan escaped her lips, creating a warm caress against his. Her tongue darted out playfully, tempting him.
