Erica begs for relief.

"Carried away?" I asked. "The only one of us who is carrying anything is you."

Rob chuckled at my joke but stayed all business. "Number one or number two?" he asked.

I sighed. After all the conflicting feelings going around my head since my shirt got caught in my seat, the continued exhibition, and the unsurpassed levels of helplessness resulted in peak arousal, I still wasn't getting what I wanted. "Number one... With a happy ending?"

"Erica..."

"What!?" I demanded. "You're worried that everybody thinks I'm a middle-schooler? Nobody can see us in here! I'd have taken care of it myself ages ago if my arms weren't bound in place."

Rob ignored me. "Number one, then. How good is your aim?"

"My aim?"

"Come on, sis. Even children understand that girls don't pee the ways boys do. I'm just trying to figure out the best way to let you relieve yourself so we can get back to our seat."

"Rob, come on. I'm begging you to let me get real relief. If I could go down on my knees, I'd do it." I couldn't believe I'd fallen so far. "Please, I'll do anything. Just let me cum."
