Erica's mom is a closet exhibitionist and she is living vicariously through her daughter.

"Mom, what are you doing?" Erica demanded in a panic. With her shirt raised above her hips, her pussy was completely exposed.

"You know, when I was about your age, I pledged to a sorority." Her mom laid back and closed her eyes, as if she was remembering. "Beta Rho Sigma. It was THE sorority on campus, so the rush process was challenging." The joyous look was replaced by one of sadness.

"Mom?"

"I made it through the first two challenges, but then they gathered all the pledges at 2:00 in the morning and told us that we would have to do the next challenge completely naked. Some of the girls undressed right there, but I... I couldn't do it." Blinking away a tear that threatened to form, Erica's mom continued with her story. "I was sent back to my dorm on the spot, and I wasn't able to bring myself to try again. But, that night, I had a dream of what the challenge would have been like. When I woke up, my panties were drenched. I've never felt as aroused in my life until that moment, but I couldn't ever act on it. I'm too much of a coward."

"That can't be true, Mom!" Erica exclaimed, attempting to comfort her mother.

"Of course, when I started to hear the stories about you, I felt that spark of excitement again."

Those words jerked Erica back to reality again. Specifically the reality that her own mom had raised the hem of her t-shirt and exposed her pussy to the passengers on the plane. "What are you saying?"

"I've realized that you must be so much more brave than me, sweetheart. So I'm hoping that you could help your mom. I couldn't even undress for my sorority. You displayed yourself, fully naked, at your high school graduation, in front of everyone. And there have been other stories I've heard, too."

"Mom..." Erica began to say.

"I mean, look at you, Erica," her mom interrupted. "Since the time we arrived at the airport together, you've taken off your jeans and your panties." Erica attempted to explain, but her mom continued to talk over her. "Please, sweetie. Just keep doing what you're already doing. Let me feel that spark again."
