When her hand turned so that their palms were touching, Peter gave her a look and frowned. Though he didn't move his hand, he instead positioned it a bit better so that it covered her palm more. He took a sip from his tea and just shook his head while looking at her as she revealed to him she wasn't joking, and then actually choked a bit on the tea when she mentioned taking him into a dark corner.
Shaking his head, he eyed her and set the cup down, still coughing to try and clear his throat, before shaking his head some more, "Sadie..." Cough. "Sadie, I am your TA, I can't do that. As much as I'd--" He stopped himself there, no, no he shouldn't lead her on or give her any reason to keep pushing. But she was beautiful, and had he been one year younger and not a TA, he'd have had no qualms of taking her up on her offer.
Still, he had to behave. He was Peter Parker, he had morals. And she was gorge--no, she was his student. Stop it, Parker, he chastised in his brain.
"I don't really know what to say, maybe if I weren't a TA, sure I'd... but Sadie. As absolutely, remarkably beautiful as you are. The moment we were caught? I'd be dead, you maybe expelled."
