"No really..."

"You think that if you show me a quick flash of thigh and give me the "no money" line I'll just say "it's alright, don't worry, have it on me." You must think I was born yesterday. It'd take more than a flash of your scrawny arse to get you a free pizza from me. Fifteen pounds, please."

Scrawny arse! The cheeky bastard, I thought. There's nothing scrawny about me. However, I knew I wasn't in a strong bargaining position, and it wasn't in my interests to get uppity with him.

"But it's true," I pleaded. "I really don't know where my purse is. My partner must have taken it for some reason."

And where was my Master anyway? Finally, now that anger had replaced my initial terror, I began to think straight again, and it dawned on me that my Master had set me up. It was he who had ordered the pizza, then told me to go for a shower; my handbag had been moved and my purse taken, and my Master was nowhere to be seen. With a sinking sense of understanding, I realised that this was my latest test. I turned to the pizza man.

"I'm calling the police," he said flatly, "I can't afford crap like this." He pulled his mobile phone from his back pocket, placed the pizzas on the hall table and made to dial.

"No, please don't," I said. "I'm sure I can find some way out of this." I let the phrase hang in the air, watching a perplexed look cross the pizza man's face before fading and being replaced by an expression of blank incomprehension. Hmm, I thought, not too bright this one: no room for subtlety dealing with him.

"I mean," I explained, "maybe I can find another way to pay." I stepped towards him, fingering my towel suggestively, flicking it up and revealing my upper thigh. "I mean, maybe you could have more than a flash of my scrawny arse." I choked on the words, hating myself for saying them, and deploring the situation I was dragging myself into. It was what my Master expected, I knew, but still, this bloke was ugly.

"A fuck, you mean?" he replied incredulously.

"It's only two mouldy pizzas, buster, don't push it," I snapped back, temper getting the better of me.

"What then?"

"Well, let's see," I said, slipping the knot of my towel. I gripped it and slid it down a fraction, revealing the swell of my breast.

"Not much there," the pizza man said. Christ, he was a charmer, this one. No doubt his idea of foreplay was yelling "brace yourself, girl". I lowered the towel further, revealing my nipple. Despite my distaste for the scene, my nipples were hard, extending to their full quarter of an inch length.

"Nice nips," he crowed. At least there was something about me he liked, then.

I smiled and pulled one end of the towel clear, revealing the left half of my body. I coyly clung to the other side of the towel, draping it over my hips and thighs, using it to cover my pussy. After teasing him for a moment, I stared into his eyes and dropped the towel to the floor, and stood naked in front of him. Turning round, I bent over, giving him a perfect view of my rounded backside, and looked over my shoulder at him.

"Not that scrawny, is it?"

"Not like that, no," he replied hoarsely.

"Now then, about these pizzas, does this little show cover it?"

"No, not nearly." Damn, I thought, I've picked a barterer.

"What would you like, then?"

"I'd like your lips around my cock." A blowjob. They always wanted a blowjob, I reflected.

"Okay, lover boy, come over here." I sat on the settee and spread my legs lewdly, giving him an unexpurgated view of my slit, lips spread and puffy and my pink gash moistly visible. He approached apprehensively and stood in front of me, staring at my body. I grabbed his belt and pulled it hard to the right, easing it from the buckle. His crotch was already bulging as I undid the button of his jeans and slid his zip down. Grabbing his thighs, I pulled at the material and yanked his jeans down to his knees, revealing a pair of Bart Simpson boxer shorts. Well, I don't suppose he expected something like this to happen when he got dressed this morning.

I fondled his cock through the material, guessing at its length and width. He wasn't very big in either dimension and wouldn't pose too many difficulties. I smiled up at him.

"Big boy," I cooed. I grasped his waist band and pulled his shorts down, letting his cock spring clear. It was quite attractive actually, uncircumcised, with his foreskin concealing half of his head. I grasped it at its based and pulled back, watching the foreskin stretch and disappear. Pushing his cock upwards, flat against his belly, I extended my tongue and licked his balls. They were incredibly hairy, probably the hairiest I had ever seen, and I could barely feel any skin as I stroked my tongue against them. Raising my head, I rolled my tongue upwards onto his shaft, pulling free from the forest of hair onto relatively clear skin. I kissed him gently on that little brown mark that most guys have on the underside of their pricks, then licked upwards, further and further, until I reached the flap of skin at the base of his helmet.

Pulling his cock horizontal, I slid it into my mouth and held it there for a moment. He emitted a groan and I felt his muscles tense. I doubted whether he would last very long and began to suck gently, rolling my tongue against the soft skin of his helmet, feeling his pee-hole and licking repeatedly against it. He thrust himself forward impetuously, but because he wasn't very large I could accommodate him quite easily and did not resist. His cock slid fully into my mouth and my lips pressed against his pubic hair and balls. He grabbed my head and forced me forward, preventing me from moving, so I sucked rapidly and forcefully, breathing through my nose. My tongue was flattened against his prick, but I tried to manipulate it as much as I could, rubbing it against him, creating extra pressure on him. He took hold of my ears and pulled me back a fraction, then forward again, and I took up his rhythm, my mouth fucking him in mini-motions, his cock deeply embedded in my throat.

He bucked faster and faster in front of me, and I knew he was about to come. I sucked harder on him, trying to induce the moment as quickly as possible. He held my face in position and thrust his cock deep into my mouth as I gobbled and gobbled, my hands clasping his taut buttocks. At that moment I heard a noise from the doorway, and from the corner of my eye I could see my Master and Nadia in the hall, staring in amazement. I tensed, and the pizza man, sensing my alarm, turned to see the two people watching open-mouthed.

"Oh fuck," he said, and came instantly into my mouth. Spurt after spurt pulsed down my throat, coating my tongue and making me gag. The pizza man pulled clear, his cock gleaming and silvery with the mixture of saliva and sperm, and turned to face my Master and Nadia.

"What the fuck's going on here?" my Master thundered.
