A/N: SPOV
Severus froze as her arms wrapped around him, and he felt a track of wetness from a tear rolling down her cheek. He hadn't been embraced like this in over a decade, and his own eyes threatened to tear up.
As she realized where she was and froze in place with her arms around him, he returned by putting his arms around her, ever so slowly and gently. After a moment, he tightened his embrace around her and savored the moment.
"You are most welcome, Nymphadora." He replied noncommittally, considering the oddly intimate position that they were in.
He released her, and turned his face in order to look at hers. The hair was pink as always, and her smile was bright and beaming as ever. Severus allowed the barest smile grace his own lips, and he knew it could even be seen through his eyes.
Her eyes were a light honey, a shade that was unusual for him to find so stunning. Yet his eyes seemed caught in hers, and he realized that this was much worse than the hug. He was too close, too intimate, and he couldn't bring himself to cease eye contact with her.
Her nose was too close to his, and he took a deep breath to try and recenter himself. It wasn't until he realized how close and inviting her lips seemed to be that he had to close his eyes and pressed his lips shut in order to close all of himself off from her.
Merlin, you're crushing over her like a common schoolboy! He chided to himself, knowing that she and Lupin were in some sort of relationship. Even if it was dysfunctional, he was not about to pull a 'Sirius Black', as it was called when he was a sixth-year. Sirius was notorious for wooing girls who were known to be dating another guy at school, as if it was his own way of showing dominance over the other men.
Severus had his own idea of how to exude Dominance. He had been tutored by fellow Slytherins, and eventually mentored by Lucius before the Wizarding War broke out.
I could just tug on her hair, hear her gasp in surprise and arousal, raising her chin for a kiss her and then gauge how much she wants me. His mind supplied wantonly as his throat gulped loudly.
Severus lowered his face and opened his eyes finally, focusing on her black boots. "I believe that will be all for this evening, Nymphadora." He didn't want to make her leave, but he also knew that he couldn't let her stay either.
So, he was frozen in place just like she was earlier, except now they were no longer touching. Salazar's Snake, please let her just leave without further incident. He scolded himself, waiting for her response.
