She doesn't know

"Hmm, must be this debris in the pool. We really gotta fix those filters," thought Jenna as she kicked away the particulate matter in the water. Her kicking motion caused her perfectly rounded breasts to sway side-to-side as she finished up helping the old folks put on their goggles. For the longest time, Jenna complained about how poorly the filters at the pool worked since the water was frequently murky, which made swimming in it rather unpleasant. Nevertheless, Jenna decided to proceed with the swimming lesson anyways.

"Alright ladies and gents! Let's start today's lesson by using the kickboards!" said Jenna as she motioned to the equipment stash. "Wait here while I get everyone a board" instructed Jenna as she energetically hopped out of the pool.. once again putting her bare buttocks on display to the pensioners as they looked on in awe.

As soon as Jenna found the boards, she gingerly made her way back into the pool, causing her breasts to bounce around with every step. When she got back to the pool, she handed every student a board and began to demonstrate the first exercise.

Jenna wanted to start the day by teaching the old guys how to float on their back. "You see? It's simple. You just put the board right behind your back and let yourself relax" instructed Jenna. She proceeded by placing the board on her lower back just as she instructed and allowed herself to float in the water.

In one magnificent instant, the buoyancy of the board hoisted Jenna's curvaceous body towards the surface of the pool, lifting he ample breasts completely out of the water. Unsure of how to react in this situation, the students remained silent and their eyes were glued to Jenna's boobs. For some reason, Jenna realized that the class was being unusually quiet but she couldn't seem to figure out why. "I guess it's normal.. I'd be pretty shy on my first day of class too" figured Jenna as she continued to lay on her board naked-as-the-day-she-was-born. Jenna decided to spend a few more moments relaxing and demonstrating how to float while the pensioners "observed" her technique. After all, she loved the way the cool breeze felt on her skin. Jenna's entire body was covered in goosebumps as it was exposed to the morning air. She even started to feel her nipples harden a bit. "Oh my! Thank God no one is able to see that!" thought Jenna as she quietly chuckled to herself.. "That would be pretty embarrassing!'

After a few moments have passed, Jenna figured it was the pensioners' turn to try it out. "Any questions about how to use the board?" asked Jenna the class while her nipples continued to face the sky. After a long, awkward silence, Jenna turned her head as she heard a voice... "Uhhh... Jenna???"
