"Very nicely done, pet," he crooned. "And now it's time for a fuck. I've waited a long time for this moment." This was true, of course. I had had a number of experiences with the hideous boy in the last few weeks, but he had yet to penetrate me. There was no point in arguing, and no escaping, so mutely I acquiesced and allowed him to move me into position. The headmaster's desk, a long and surprisingly narrow mahogony piece, was in front of us, and Clive pushed me towards it. I bent over it, splaying my body against the cold wood, my breasts flattening on the surface, and gripped the opposite edge. Clive pulled at my thighs, forcing me to stand with my legs wider apart and raising my bum, ensuring he had clear access.

I felt him position himself behind me, and his hand was on my pussy, his fingers stroking my labia and thrusting impatiently inside me, pounding at me without finesse. He spread my lips apart, and I felt him press clumsily against me, his fingers trying to find my opening, and the head of his cock brushed against me. Finally he found his spot and pressed hard, forcing himself into me. It hurt and I winced and groaned. All he had to do was slow down and ensure that my lubrication covered his cock, easing its passage inside me, but he was raw and inexperienced, and the more he felt resistance the more he pushed. I grunted and forced myself hard against him, impaling myself on his cock, feeling it slide all the way inside me. Moving my hips slightly back and forward, I began to create a rhythm, with each movement feeling his cock slide more and more easily against me, until it was fully lubricated and slipped easily in and out.

He wasn't very good, thrusting energetically but uninspiringly inside me, never changing rhythm, nor adjusting his angle, nor creating any lateral movement. His thrusts were pressing me hard against the edge of the desk and it was proving uncomfortable. To take my mind off it, I eased my hand down to my pussy and began to play with my clitoris, rubbing my first and third fingers either side of it, while my second finger rolled delicately and deliciously over the top of my hard, swollen nub. Amazing sensations became to whirl around me, vibrant and elusive, as I contemplated my situation, acting as a learning tool for this gauche teenage boy, having to ensure my own satisfaction while he hamfistedly worked out what went where, and how, and why.

From the corner of my eye I could see Richard standing watching us. His cock was now competely rigid again. Indeed, it had scarcely gone down since I had brought him off, and he looked ready for action again. Schoolboys do have some redeeming features, I suppose. Fixing his gaze in mine, I motioned with my head for him to come forward, and he approached, timidly. He moved round to the other side of the headmaster's desk and his erection stood stiffly in front of me.

I reached forward, my mouth open like a feeding chick awaiting a meal from its mother. Richard took his cock in his hand and guided it towards me, and I felt it slip between my lips, his purple helmet, sleek and hard and hot, filling my mouth. I rolled my tongue around it, feeling for the delicious flap of skin at the base, and stroking my tongue upwards until I felt his eye; I grazed my tongue over it a few times and began to suck hard. Immediately he thrust himself forward, and his cock slid deep within me, far down my throat. He was so big I couldn't take his entire length, but I accepted what I could, feeling his massive size engulfing me. He may only have been young, but his was the biggest cock I had ever sucked.

I began to rock my body back and forward, trying to merge the rhythms of Clive behind me and Richard in front. Richard took my lead and began to move in time with me, his cock sliding emphatically and amply in and out of my mouth to a regular, rhythmic beat. I pushed further and further, trying to take more of him with each pass, feeling his cock slide deeper and deeper down my throat. Resisting the gag reflex is the key, and I relaxed myself as much as I could, not forcing, allowing myself to get used to the experience. Gradually, I found I could accommodate more, until finally, I felt my mouth slide to the very base of his cock and my bottom lip pressed against his balls. Richard slid back again to the full extent of his cock, until only the tip of his glans was still in my mouth, and pushed forward once more, the whole way. I sucked in hard, ensuring that the walls of my mouth grazed against him as he pressed into me to his fullest extent and then pulled back again. On and on, over and over, he fucked my mouth, filling me with his cock. Having just come, this time he had plenty of staying power, and my jaws began to ache.

Meanwhile, behind me, Clive was still prodding away at me, pedantically and monotonously thrusting inside me, and I felt him speed up as his climax approached. I gripped him tightly with my pelvic muscles, contracting and releasing them, building up a wave of pressure against his cock. As expected, that was enough to send him over the edge, and I felt him begin to spurt inside me.

Freeing my hand from my pussy, I gripped it to Richard's cock and began to wank him savagely into my mouth. Almost instantly, the extra pressure took its toll on him and I felt him, too, begin to come. First Clive, and then Richard let out a groan and started to fill me at either end with their seed. Richard, his cock embedded deep in my mouth, spurted his hot come far down my throat and I swallowed voraciously, feeling at the same time the hot spurts of Clive's spunk shooting up me. I lay flattened against the desk as each of the boys sated themselves, came to a stop and pulled free from me.

"It must be little Jenny's turn, now," said Clive. Each of the three of us turned to look at Jenny, frightened and embarrassed, in the corner.
