Caught.

Beth's efforts yielded their results on her body, and a quivering orgasm washed over her. "Ahhn! Unhn! Ahhn!" Beth whimpered and moaned, biting her lip hard to avoid screaming. Her feet gave out and she sat hard on the tile floor, shaking with the aftermath of her deed. She washed her hands and straightened her clothes before exiting the bathroom.
"Have fun in there?"
Beth shrieked with terror and spun to face Billy. He was leaning against the wall next to the bathroom door. She noted, with horror, that he was holding his phone sideways, in both hands.
"Mr. Preston, what the hell do you think you're doing?!" Beth tried to sound as stern as possible, but she was shaking with terror. Did...did he record me?
"Oh, just passing the time. Same as you apparently." He turned his phone to face her. It was a view through the bathroom door. Apparently, she hadn't shut the door all the way. STUPID. STUPID! STUPID!!! The video had captured everything, and Beth reached for the phone by reflex.
"Give me that!"
Billy snatched his hand back. "Nuh uh, Miss Wilson."
"You....you're not allowed to have your phone in detention..." It was an incongruous protest, given what Billy had witnessed and recorded.
"That's true." Billy laughed. "But I'm pretty sure you're not allowed to masturbate in the bathroom as a teacher either."
"I can't believe you recorded me! When Mr. Schiff finds out, you will certainly be expelled."
"That's true. But I'm probably going to get expelled soon anyway... you on the other hand, you're pretty much done as a teacher if this video gets out."

}Beth stomach dropped. No. "Please....Billy. You can't do that." She looked at the floor for a few seconds, and then sighed. "I'll do anything you want." {else
}Beth felt tears welling up in her eyes as she realized exactly what her predicament was, and what she would probably have to do to get out of it. "Billy, please...please don't do that..." she looked at him, and his smile told her that he wasn't going to let her just walk away from this. "What...what do you want?"{endif
