Bloody hell, Terrence was hit hard by that. And well - that made Zach lean toward the animal theory. Because really, he couldn't imagine a teacher purposefully making that happen. It wasn't the most attractive kinds of hitting on her, and most of it brought the boys down to a thirteen year old level. Not in T's case, of course, though it was still bad.
"It takes an active effort to resist," Zach didn't like the disappointment in T's voice. And he had been reading up on some stuff since witnessing it. And some straight men had, according to the books, been able to resist, if they tried hard enough. "Your body will have a reaction, but you can treat it like background, so that it doesn't dominate," he hadn't exactly had a lot of experience teaching. Learning and following other people's advice yes. But even though he knew more, explaining was hard.
