"Master?" I asked, head bowed.

"I enjoyed your performance with Pete very much, Harriet," he smiled at me. "I think I'd like the same."

I crawled closer to him and rested my elbows on his knees. Grabbing at his belt, I unbuckled it and reached for the button and zip. It was the work of a moment to reveal my Master's beautiful cock. I smiled and drew it into my mouth, commencing a sucking routine which was by now as familiar to me as brushing my teeth. My Master had trained my to perform exactly as he desired, and I knew to lick up and down his length slowly and carefully at first, interspersing this with brief darts with my mouth over his head, sucking and pulling it into me, feeling him grow under my ministrations. It never failed to excite me, the sensation of his cock hardening as a result of my touch.

Out of the corner of my eye I could see that Pete had positioned Barbara against the chair, kneeling on the carpet, her face in the seat and her arms sprawled over the arm rests. He was completely naked himself by now, and was about to enter her. Holding his prick, he manoeuvred it into place and thrust himself forward, forcing his cock deep inside Barbara's pussy. At least I assumed it was her pussy, although I couldn't tell from my angle; it went in too easily, and she didn't show enough reaction, for it to be anywhere else. Barbara seemed calmer now that my Master and I were engaged in our own activity and she was not the centre of attention; she arced her back and thrust herself backwards to meet her husband's cock, her hands gripping at the armrests, mouth pulled into a rictus of erotic tension.

A sudden slap from my Master alerted me to my task in hand or, more accurately, in mouth, and I redoubled my efforts to give pleasure to him. I had never fully got to grips with deep throating, and still had a tendency to gag; as long as the cock didn't thrust too hard or suddenly into my mouth, however, I could manage to accommodate more and more. My Master knew this, and was content to let me work at my pace, gradually sliding him deeper and deeper into my mouth and down my throat, until my lips were touching his hairy balls. As he slid in and out of my mouth I sucked in my cheeks, feeling them graze against him, sucking harder and harder. Occasionally, I would slide it almost totally out of my mouth and retain only his purple helmet. drawing circles with my tongue around its sensitive flesh, probing at the delicious, slightly swollen eye, licking at the delightful, intriguing flap of flesh where the flesh of his cock joined his tip.

Suddenly I felt my Master's hand on my chin, drawing it upwards, pulling me away from him, and I eased myself back on my heels. He motioned to me to lie backwards. I did as commanded, feeling the coarse pile of the carpet on my back. My Master pushed at me and indicated that I should move forward. I wasn't sure what he meant, but I slid a couple of feet across the carpet. Again, he motioned me forward, and now I realised what he intended. A couple of yards or so away from us, Pete was still fucking Barbara against the chair. This was my destination.

I looked at my Master reluctantly, but he returned my look with a resolute stare, and I dragged myself backwards towards Pete across the carpet, feeling it graze painfully against my skin. Once in reaching position, I grasped his ankle; surprised, he momentarily lost his stride, but quickly regained it and grinned back at me. I eased myself into position beneath him, sliding my head between his outstretched legs. As I did so, Pete pressed on Barbara's hips, forcing her to hold herself lower; Pete followed suit and lowered himself onto my waiting face.

He was hot from his exertions, and smelled very musky. The top of my head was right up between his legs, and if I raised my eyes I could see his cock slide in and out of Barbara's sodden and swollen pussy. He pressed downwards and I slid my tongue out to meet him, grazing it once more against his perineum, sliding it up and down that curious, exotic, unusual line of skin between his balls and arse.

As I did so, I felt my Master's hands at my thighs, and I opened them wide for him, affording him easy access to me. With a shiver, I felt his cock probing against my lips momentarily, and then sliding easily inside me. He rested inside me at his fullest extent momentarily, and then began to ride me firmly and hard. I could sense his excitement, and it rubbed off on me as I lapped at Pete's balls. Grabbing at his arse cheeks, I pulled them apart and he pressed down on me, until his arsehole was directly on my tongue. I pressed against him, having to contend with his lateral movement as he continued to fuck Barbara. Sometimes he would slide agonisingly away from me, but would return soon enough, and I continued to lick and rim him, as my Master's cock slammed into my sopping wet pussy.

Pete's movements got faster and faster, heralding his climax, and I pressed as hard as I could against him. I gripped his thighs and cricked my neck, raising my face to meet him as he made his final few thrusts into Barbara's pussy. I had an amazing view of proceedings, mere centimetres from the action, and I watched, fascinated, as his movements changed from hard and fast to slow and long, pressing himself firmly against her. His bottom began to clench involuntarily as the climax spasmed through his body, trapping my tongue between his cheeks for a moment before releasing it, then trapping, releasing, trapping, releasing. He grunted as his come spurted into Barbara, a final, few, trembling thrusts, and as he relaxed, in the moments after his climax subsided, his legs widened and hips lowered, pushing his arse harder against me.

My Master had been observing the action from his own vantage point, not as close as mine, but near enough. I knew his responses well enough to be able to gauge his movements, and could always judge his progress. I could sense now that he was close, and began to grip my pussy walls against him, relaxing and gripping, relaxing and gripping, creating a continuous, insistent wave of pressure against his hot and thrusting cock. I didn't do that often, because I knew it had a profound effect on him and I generally had no desire to shorten proceedings. I sensed, though, that tonight we were at the start of events, not their culmination, and I happily hastened his first climax of the evening.

Still rimming Pete, I rode against my Master, bucking and thrusting under him, as he careered towards his climax. Pete's cock, by now, had softened, and I noticed it slide, with a sudden plop, from Barbara's pussy; it lay, still glistening with their mixed fluids, only inches from me. Moments later, at the very instant when my Master began shooting his sperm deep inside me, I observed gravity drag Pete's slowly from Barbara. Craning my neck and gripping at Barbara's thighs, I drew my mouth underneath her, and was rewarded by a few drops of Pete's come dripping into my mouth just as my Master made his final few thrusts into my pussy, leaving it filled and contented.
