"Harriet, last warning before a spank."

Without replying, I got up and pulled my skirt down, making myself as decent as I could. Looking around, I was aware of a wave of tension around the entire area, and could see that I was the subject of myriad sly glances. Clearly, my performance had not gone unnoticed, but then the sight of a woman openly masturbating in a public arena is likely to attract one's attention. I walked towards the reclining Newcastle fan and stood as close as I could get to him, knowing that in his prone position he would be able to stare, once more, right up my skirt.

"Hi," I said. "Enjoy that?" He nodded. "I'm a bit hot now. Need something to occupy me. Can we go to your tent?"

I actually thought he was going to refuse. A look of panic masked his face, his eyes wide and startled, darting in alarm. Bet he's a virgin, I thought. I stretched out my hand, showing that I would brook no argument, and he caught it weakly, his palm hot and sweaty, like warm rubber.

"Howway then," I said, as jauntily as I could muster and in my best Geordie accent. We walked self-consciously to his tent, and I don't know who was the more apprehensive. Once inside, he looked at me and smiled ineffectually.

"Gary," he said.

"Pleased to meet you, Gary," I replied, proffering my hand. I concealed a laugh as he reached out and shook it solemnly. I grabbed my tee-shirt and hauled it over my head them as he watched avariciously, peeled off my skirt and sat before him in nothing but my trainers. I nodded at him sardonically, and he took the hint and began to strip. He was a very large boy, swathes of fat bunching beneath his football top and as he divested himself of the top a considerably more impressive pair of tits than mine emerging. He faltered, courage failing him, and I took command.

"Allow me, lover boy." I pushed him onto his back and fumbled with his trousers, unbuttoning them and sliding them over his gigantic thighs. His cock was already erect and I could feel it through his boxer shorts. I gripped it and squeezed hard, making him groan. It didn't feel very large, nor thick, and I reflected that this might be one of the less intrusive blowjobs I had had to endure.

"Big boy," I cooed. Gary grinned and folded his hands underneath his head. I tugged at the boxers and pulled them clear, revealing his cock. As I had suspected, there wasn't much there, although probably half its length was concealed by the layers of blubber. Lose three stone, I thought, and you could gain an inch on that cock. I might recommend that to him later, but not yet, I didn't want to discourage him. It wasn't a very pretty cock, truth to tell, small and pencil like, with wispy, inconsequential pubic hair forming into an unassured and straggly triangle, and volcanic craters of cellulite pocking his skin.

I turned round and swung myself over him, perching my arse over his chin. I looked back and stared at him.

"Look, but don't touch," I warned. My Master had only told me to give him a blowjob, and I felt disinclined to offer any additional services. "Got it?"

"Yes," he moaned, his breath heavy and fast. Poor guy had probably never been this close to a woman before. I grabbed his cock and wanked him rigorously for a few seconds, feeling him very hard in my hand. I'd have to be careful, I thought, or he'd come before I got my lips near him. And technically that would be a failure in my Master's eyes, because I wouldn't have given him his promised blowjob. Panicking at the thought of what punishment that might bring, I bent forward and lowered my mouth towards him. Holding his cock upright, I slid my lips around it, brushing them against his head and feeling the heat emanating from it. I bobbed my head down and slid his entire length inside me. No chance of gagging on this one, at least. I sucked at him and scratched my nails along his balls. His breath was hot on my arse and I wiggled it for him, lowering myself until I could have been no more than an inch from him.

He was beginning to jerk, alerting me that he wouldn't last very long. I sucked in hard, dragging my cheeks against his head and sliding my head up and down, rasping my tongue along his shaft and rippling it up towards his sensitive head. I pulled my head clear.

"Enjoying the view?"

"Yes."

"Want to see more?"

"Yes."

I felt downwards and stroked my index finger along my pussy lips, sliding it against their sensitive flesh and feeling the heat and moisture from them. Bringing my middle finger up to join it, I eased them inside me, parting my lips and revealing for the prone Gary my pink and excited cunt. My fingers were coated with my juices and I leaned back, sliding them into Gary's mouth. He sucked appreciatively, licking them clean, and I turned and resumed my ministrations to his cock.

I slid it into my mouth again and gripped my hand around the base of his shaft, squeezing it tight. He was jerking regularly now and I began to wank him with a regular, forceful rhythm, all the time sucking and licking. My fingernails resumed their crawl across his balls and down to his perineum, and after only a few more seconds I felt the first violent thrust of his climax and a sudden spurt of liquid filled my mouth. He groaned as I wanked him through his come, the spunk flying into me in spurt after spurt and coating my tongue. I continued to pump his cock until I felt it subside and swallowed his come as I slowly slid it from my mouth.

"Okay?" I asked.
