Take out the gag to talk to her

Whatever thoughts this put in your mind, you wanted to get an explanation of what was going on before you did anything. You reached behind her head, then carefully unclasped the gag.

"Th- Agh." She winced and flexed her jaw, then spoke again. "Thanks. Ugh. That thing has been in my mouth too long."

"What happened?" You asked. "How did you get like this?"

She looked away. "... It was supposed to be some... Well, some light sorority hazing, only they managed to turn it around on us. We weren't actually going to leave the freshmen out here alone, but they didn't know that. ... And since we told them we had told the football team to find them out here, they probably haven't figured out yet that they need to come untie us."

That was... quite a bit of interesting information actually.
