-She- Doesn't Know!

The hour and a half long class was nearly over, Jenna was still completely calm and oblivious to her nudity while Abbey was vibrating with nervous energy and embarrassment to her own.
There were moments when she found the attention intoxicating and worshiped herself like a goddess but then she would hear a snickering word or conspiring giggle from one of the girls sitting behind her to make her feel as out of place and **** as she was. When she had pictured this idea in her head she had thought she might be brave enough to go topless but she hadn't really ever intended to go fully naked. Nor did she expect quite such an audience.
Still she knew pictures were a certainty bringing Mark along who was still happily alternating between snapping away and taking 5 minute long HD videos. Still though, if the girl Abbey convinced to wear a bikini for the first time as a highschool Sr while she herself was a freshman was comfortable like this then she could be to!

The professor continued to spice up her normal routine of poses with ones specifically meant to embarrass the two naked girls with increasing frustration at the lack of effect it was having on Jenna. Ending with a semi advanced position known as "bird in flight" the position was reached by first getting on all fours, a position that already made Abbey blush and would have mortified Jenna had she realized the aroused and overall naked state she was currently putting on display for more than 250 on a live stream of classmates and their friends. The hands were planted a little more than shoulder width apart with the elbows bent at 90 degrees, then using her arms as platforms for their knees the two naked girls along with the rest of the class attempted to lean forward and balance all of their weight on their arms.
Both Jenna and Abbey had excellent balance and were soon resting with their asses in the air fully on display for several minutes as the professor went around and helped the other students who were struggling.

Abbey wasn't sure if she could blush any harder, in fact she could just not how she pictured.

As a wave of embarrassment shot through her due to her lude and open position. She felt the familiar warmth spread throughout her body centering itself not to her cheeks but instead between her legs. The dozen or so cameras pointed at her and her naked mentor saw her lower lips darken with a deep blush and her inner lips to part just slightly.

After what felt like an eternity to Abbey and was truthfully beginning to wear on Jenna's arms they were instructed to get up and grab some water.

Abbey was glad the class was ending she had so far avoided a panic attack but was ready to be done with this adventure.

"Alright class well done," Said Professor Whiteside loudly. "Just one more thing before our cool-down stretches..."
