Nope; gotta rub it out in front of everyone

The volleyball slammed on the floor, right where I had been standing ... because I had bolted for the exit to the gym.

"Stacy!" Coach Summerville shouted while the opposing team cheered. "Get back here right now!"

The fury in his voice brought me to a halt. I'd almost reached the door, but I paused for an instant to consider the ramifications for deserting my team. Would I be able to play volleyball ever again?

But all thoughts drained from my mind as my urge to orgasm overwhelmed me. Any possibility of escape fled as I jammed my right hand into my shorts and started to moan.

I could tell that I was causing quite a stir, but the details were fuzzy - and anyway, in light of my irresistible urgency, I couldn't focus on anything else anyway.

I dropped to the floor and spread my legs, my hand furiously rubbing my clit. I writhed in my sweaty uniform, and though my hand and privates were concealed from view, my public lewdness was on full display. The now-familiar-but-still-fresh sensation of a powerful orgasm swelled within me, and I let out a howl of pleasure and delight.

Finally, I came to, my eyes fluttering open and coming to focus on an outraged Coach Summerville standing nearby. His rugged chin and gray-speckled black hair loomed large as his whistle dangled ominously. The roar of the small crowd was obvious behind him, with dozens of cell phone cameras still straining to catch the continued action.

"Get. Up," he seethed. I stood and approached him. As I did, I was surprised to see his features soften. It was slight, but noticeable. His rage had calmed into annoyance.

"I'm sorry, Coach," I sobbed, mortified at my public exposure. "I can explain."

He looked at me, long and hard, his eyes running up and down my trembling body. "Later," he said. "Just get back out there for now."

Relieved at this reprieve, but still subjected to the humiliating catcalls of friend, foe, and stranger alike, I resumed my position. I tried to play as best I could, channeling my embarrassment into action, but it was no use. We lost miserably, and I hung my head in shame as I headed to the locker room with the team.
