Jenny tries to help, but...

You let Miss Nolan get to her feet this time, Simon in front of her. The poor boy had somewhat smartly decided to stay on the ground, crossing his legs; trying to get up hadn't worked very well, and it would only serve to give the growing crowd a better look at the growing bulge at the front of his slacks. The two of them were so disoriented and embarrassed that it took them a second to realize their position- with Simon's head at Yvette's feet, he was getting a clear view up her skirt!

Simon sputtered apologies, his hard-on definitely not disappearing any time soon, while Miss Nolan slowly started to back up, but as she did...

"Here, let me help, I--" Jenny, having recovered her footing well enough to move a bit started forward, hoping to help her friend and authority figure, but a flick of your wrist, and she slipped once more. Worse yet, she pitched forward this time, and in her scramble to catch herself, her hands found the back of Miss Nolan's skirt. She fell on her face, and Miss Nolan fell forward onto... something else.

Dazed from the impact, it took Yvette a second to realize what was jabbing her in the cheek. To her shock, and to laughter and camera clicks of the crowing crowd, she realized it was Simon's clothed erection. Meanwhile, she jolted as vibrations ran up her thighs, her panty clad crotch resting on his mouth as her big ass smothered his face. To be caught in such a position with a student, even accidentally, was horrifying for Miss Nolan! She knew she had to act quickly, or the situation might get even worse...
