Tonks knew she couldn't exit the library right after Severus. She picked up a book just in case someone walked in and tried to use her reflection in the glass of the coffee table to smooth out her hair and calm her expression. She cast a concealment charm on the pink mark on her neck left by his teeth and lips. Waiting just long enough to ensure the coast was clear, she ducked out amidst the commotion of trying to once again quiet her great aunt. Just as she was about to apparate back to her room, to retrieve her list, a voice called out from the shadows of the hallway.
"Nymphadora, a moment please."
Tonks turned quickly, just in time to Mad-eye's form limp from the darkness. She was glad she had the now old comeback to resort to since she felt very much like she had just been caught, "Tonks, Mad-eye. My name is Tonks."
Mad-eye ignored her. "Eh…Is…Is everything alright? With Lupin, I mean?"
Tonks tried hard not to sigh in relief and felt her face soften when she realized the honest concern that was present in his voice, even if he wasn't the best at showing it. "It's…It's complicated." She answered truthfully.
"Right. Well don't let him get to you." He smiled reassuringly.
She smiled back. "It's been a long day Mad-eye. I just need to go back to my room."
"Well you know you can contact me if you ever need to."
She smiled at him again, "Of course." She said before apparating back to her room, glad he hadn't asked too many questions and she was able to keep her responses general and honest.
Once back in her room she quickly gathered up her "homework" to give to Severus, the images from the library running around in her mind, his taste still on her lips. She knew he was waiting on her, possibly unsure if she would even show. At this moment she couldn't think of the slightest reason why she shouldn't, nor could she recall the last time she had felt this reckless or this excited.
She removed the concealment charm from the mark on her neck, smirking at herself in the mirror. Looking at the broader view of her reflection she wished she had something more "appropriate" to wear. She had no idea what Severus found attractive, but she highly doubted that pants, combat boots and a Weird Sisters t-shirt constituted as sexy, submissive attire. Glancing at her closet she knew it was a lost cause. She had never really favored sexy clothes in the first place and even so, she had packed for patrols and duty. On the other hand, he hadn't seemed to mind what she was wearing back in the library. The Library. She grinned broadly as she recalled their kiss, held the list close, and apparated to the gates of Hogwarts.
Sticking to the shadows she quickly made her way across the grounds and through the castle, only having to quickly scold one Gryffindor third-year who was out past curfew. She felt like a student herself as she approached Severus' office and quarters. She had always worked hard when given an assignment and always cared deeply about a professor's response to and approval of any given work. It was that characteristic, along with her unyielding sense of loyalty, that had placed her in Hufflepuff. Even so, very few things in her life had ever seemed to carry the weight that the "homework" she currently held in her hands did. She took a deep breath and knocked on the door, trying to school her emotions, that were caught somewhere between the desire to jump up and down or run away, into something a bit more dignified. Leave it to me to be able to calmly face Death Eaters, but knock on a door? That has me running scared. Her mind tried to argue that behind this door were chains, a bed, implements of pain and pleasure and a man who knew how to use them all and use them well. She was about continue the inner argument when the door started to open and her mind went blank.
