I was very conscious of the fact that only three weeks remained before the end of the school term. Only three more lessons with Sarah before her mother carried out her threat of withdrawing her from me and placing her with another teacher. Obviously I had to make the most of that time, and abuse the lovely little girl at every possible opportunity as I could before I lost her forever.

The following Wednesday, Sarah and Mr. Harper turned up bang on time, and I welcomed them very cordially. "I thought we might have another double lesson today, Mr. Harper," I said, as soon as I closed the door. "It seems to me that we've reached a crucial point in Sarah's education, and we don't want to spoil the ship for a halfpenny's worth of tar."

Sarah's lip trembled, but her father looked very excited and pleased. "Oh yes," he said. "I agree. Two hours should allow Sarah to… umm…"

"…to fit a great deal in," I supplied. "Absolutely. Now, we could try some scales and arpeggios, to start with - or we could go straight up to the bedroom. Which would you prefer? In my view, the emotional and physical aspects of Sarah's tuition probably take precedence at the moment."

"Of course," Mr. Harper blurted. "The… the bedroom, I think."

So up to the bedroom we went. Sarah looked very woebegone as I ordered her to strip for us, and very scared as we took our own clothes off. Once again, she was face-to-face with two massive hard-ons. But this time, she had a much better idea of what she was in for.

"Now, Sarah," I said to her, in a gentle and reassuring teacher voice, "sometimes when you go into a bedroom with a man, to have sex with him, you'll have to help him to get his cock hard so he can enter you. I'd like you to put your hand on your daddy's penis and move it gently backwards and forwards, like this."

I stood in front of her and wanked myself off brazenly, my cock right in her face. Sarah blanched and shied away. Grinning, I stepped aside, and Mr. Harper eagerly took my place, his massive truncheon of a dick thrust out before him.

I took Sarah's hand, and placed it on her father's hugely erect cock. The idea that his hard-on needed any helping along was utterly absurd, but he groaned in delight as his little girl, with my gentle encouragement, began to wank him off. And if he noticed my slightly crude language, he didn't make any objection to it.

Sarah's facial expression became more and more tragic as she manually serviced her daddy's dick, but Mr. Harper didn't seem to notice. He was very much enjoying the hand job he was getting, especially once I helped Sarah to improve her masturbatory technique. "Look, Sarah," I said, once again thrusting my own hard cock right in her face. "You have to peel the foreskin all the way back from your daddy's knob with each pull, and then slide it forward again like this."

"Oh god!" Mr. Harper gasped, as Sarah put my tuition into practice.

I let her carry on wanking him for another few minutes, then I stopped her, made her cup her hands, and poured a generous helping of sexual lubricant into each. "You know where your daddy is going to put his penis next, don't you?" I asked her. "If you rub this all over it, it will go into you a lot more smoothly."

Sarah rubbed the lube well in, and I asked Mr Harper if he was ready to fuck her. I said "make love" rather than "fuck", of course, but to be honest, I think even if I'd said "rape", by this time the answer would still have been yes. He was so horny, he would probably have screwed a dog right then if that was all that was on offer. There was no way he was going to resist Sarah's welcoming little pussy.

I moved Sarah, with a hand on her shoulder and one on her thigh, so that she was lying full-length on the bed. Then I knelt over her and pulled her legs open wide, obligingly exposing her beautiful, hairless twat-gash.

I was kneeling astride the twelve-year-old's head, my arse right in her face, so she couldn't see her father as he climbed onto the bed and got into position. Her whole body trembled when he lined up his gigantic erection with her quim, his swollen glans pressing against the entrance to her tiny sex hole. Then he pushed, smoothly and firmly, and inch by inch that stupendous column of gristle slid into her pre-teen body.

Sarah yelped and sobbed. These are off-putting sounds for a man in the throes of passion, so I shifted my position a little and lowered myself over her mouth, gagging the little girl with my arse. She was still moaning - and in the process sending thrilling vibrations through my rectum - but the sounds were too muffled to distract Mr. Harper as he started to pump his huge manhood in and out of her kiddie playground.

Just as he had last week, he went for full penetration, heedless of what damage he might be doing to Sarah's far-from-mature vagina. He was carried away by passion, eager to bury his cock in that delightful orifice, all consequences for now happily forgotten.

We were face-to-face, and I gave him an encouraging smile as he energetically shagged his little girl's slit. "This must be a huge relief to you both," I chuckled. "I imagine you were very keen to continue this beautiful exploration of your sensuality. It must have been hard to be living in the same house and not to be able to make love under your wife's watchful eye."

"It - - it was very hard!" Mr. Harper grunted, still thrusting.

"Well, don't hold back," I encouraged him. "A young girl's vagina is very elastic, Mr. Harper. Sarah can take everything you can give her - and she wants it!"

Mr. Harper didn't need telling twice. He was already driving his huge dick into Sarah's hairless pussy quite hard. Now he cut loose and slam-fucked her, groaning in ecstasy as he did so.

I benefited from this in two ways. First, it made Sarah shriek and moan with even greater intensity, and though the sounds were extinguished almost entirely by my bum, pressed to her mouth, the pleasant vibrations came through all the stronger.

And second, it made Mr. Harper reach his orgasm more quickly. After only ten minutes of fucking, he gave a loud, ragged yell and bent forward, shuddering as he emptied his balls into Sarah's pre-teen twat-hole. Probably those ten minutes felt very long to the helpless, abused twelve-year-old, but as you can imagine they passed very enjoyably for me.

Mr. Harper pulled himself together and withdrew his wilting dick from Sarah's savagely abused vagina. It had healed remarkably well, all things considered, from the pummelling it had received the week before, but now it looked as though someone had attacked it with a broom handle and then poured some semen into it as an afterthought. It gaped indecently, unable to close, and the lips of the little girl's vulva were red and swollen.

"Now you go and freshen up," I suggested to Mr. Harper. "The shower in the guest bedroom is all laid out for you. And I'll clean Sarah up while you're gone."

"Thank you, Mr. Glover," he panted. "Sarah, stay here with Mr. Glover. I'll be back shortly."

"Take your time," I told him. "Actually, I've suddenly remembered that the shower in that room isn't working. You'd better run yourself a bath."

Sarah didn't say anything, because her face was still buried under my arse.

As soon as Mr.Glover was gone, I climbed off her, jumped off the bed and closed the door. Then I turned to examine my prize. Sarah's face was a hectic red and her eyes were glazed. Her breath was coming fast and shallow. It was really arousing to see how profoundly that savage fuck had affected her, and to think that the brutal rape of this lovely child was in a sense all my work. Left to his own devices, Mr. Harper might never even have kissed his little girl, still less violated her tiny pussy while I sat on her face!

And now I was going to receive the reward for all my selfless efforts. I climbed on top of the gorgeous pre-teen girl, who moaned in sincere terror at the sight of my turgid cock and eager expression.

"It's all right, Sarah," I reassured her. "My cock is only an inch or so bigger than your dad's. And now that he's stretched your cunt, you should be able to fit me in just fine."

Lowering my weight onto her, I shifted around until the tip of my blood-gorged knob was up against the entrance to her ravaged hole, and shoved hard.

Sarah gave a wail of anguish as my huge manhood embedded itself inch by inch in her sweet little cock-socket. I silenced her by clamping my mouth onto hers and kissing her passionately, my tongue delving past her tonsils.

God, her cunt felt so good! I'd dreamed for so long of cramming my grown-up cock into a tight, child-sized pussy, feeling over-stretched vaginal muscles surrendering as I forced my way into that most forbidden of territories.

I was dizzy with pleasure. I couldn't believe any feeling in the world could be so intense, and so wonderful. I started to fuck Sarah with deep, slow strokes as she trembled and writhed in my arms, moaning urgently into my hot mouth. I was getting more and more cock up her with each determined thrust - assisted by the natural lubrication provided by Mr. Harper's ejaculate. My dick was so enormous in comparison to her little treasure chest, it seemed inconceivable that she could accommodate it all. On the other hand, it was also inconceivable that I could stop before I'd forced this beautiful child to take every last fucking inch of my massive, grown-up cock.

The going was getting harder. My glans was hitting an obstacle that was almost certainly the neck of Sarah's womb, but I continued to pump my dick vigorously in and out of her body. I was convinced that there was still some leeway. As I'd told Mr. Harper, little girls' vaginas have a natural elasticity. Surely Sarah's could swallow a mere ten inches of adult cock, so long as I didn't make the mistake of taking mercy on her.

I thrust harder and harder, pistoning my cock into that sweet little hole, which now seemed so determined to resist me. The loud squelching sounds from Sarah's cunt, and the little girl's muffled moans of pain and alarm against my crushing lips, were the only sounds in the room.

Until, suddenly, they were interrupted by another sound.

"Mr. Glover!"

I looked up to see Sarah's father standing in the doorway of the room, staring down at us in utter horror.

Reluctantly, and after a few more deep thrusts, I pulled my huge hard-on out of Sarah's cunny.

"What… what's the meaning of this?" Mr. Harper spluttered, stepping into the bedroom. "It's not acceptable! It's not appropriate at all! You can't do this to my daughter! This is… you're taking sexual advantage of her!"

I climbed off the bed and stood, facing him. "Not at all," I said, coolly. "Mr. Harper, this has always been about allowing Sarah to discover passion, so that that passion can be reflected in her music."

"Yes?" Mr. Harper demanded belligerently. "So?"

"Well, passion is about more than just love, Mr. Harper. When you and Sarah have sex, it's infused with a gentleness and consideration that's very touching to see. But sometimes, passion is about the rough and the dirty and the crude - about doing what feels good, and saying fuck the consequences."

Mr. Harper's expression didn't change, but at least he stopped shouting. I gestured for him to sit on the bed, and he did. Sarah had rolled onto her side and was clasping both hands to her over-stretched and half-ruined cunt. For the moment, we both ignored her, although she looked very cute and I was keen to finish what I'd started. My gigantic erection hadn't gone down by a millimetre.

"If Sarah is going to be fully in touch with her own passion," I said, "and fully accepting of it, she'll probably have sex with lots of different men. She'll come to enjoy being penetrated by men's cocks, whether there's love involved or not. I was helping her to explore that experience."

Mr. Harper still looked doubtful. "You seemed to be being very rough with her," he complained.

I nodded, although I was thinking about pots and kettles. "Yes," I admitted, "that's true, Mr. Harper. But again, I was thinking of her pleasure. Most women love to fantasise about being raped. It allows them to imagine themselves engaging in depraved and disgusting sex acts without admitting that they want to."

"Really?" Mr. Harper looked surprised, but definitely interested - especially, I was fairly sure, in the depraved and disgusting sex acts.

"Oh yes," I said, straight-faced. "Being sexually violated by a stranger -crudely and roughly - is a very arousing fantasy for the vast majority of women and young girls. It's right up there with being fucked by two men at the same time."

Mr. Harper's eyebrows went halfway up his head as he considered this.

"You can see why," I observed casually. "For a young girl to have the full attention of two adult men, and to bring them to sexual ecstasy with her body… That's very empowering."

"Yes," agreed Mr. Harper, looking down at his raped and dishevelled little girl, still in a near-foetal huddle on the bed. "I suppose it is." His cock was starting to come to attention again.

"Perhaps," I suggested, "we should fulfil that fantasy for Sarah right now. I'm sure it would give her a lot of pleasure. And I can see, Mr. Harper, that you're ready to do your duty again…"

He hesitated for a long time. This was make-or-break, and I waited for him to make his decision. But I did help it along with one final observation. "We don't have much time," I reminded him. "Sarah's musical education is about to be taken out of our hands. So if we are going to do this…"

Mr. Harper nodded. That argument went home. It was only in the context of my lessons that he could violate his pre-teen daughter and be reassured that it was for her own good. He'd only just begun to explore the pleasures of paedophile sex, and now he faced the prospect of having them snatched away from him again, in only a few weeks time.

"All right," he said, at last. But he immediately looked scared and doubtful. "You… you really think that this is something a young girl would fantasise about?"

I nodded vigorously. "Think about it, Mr. Harper," I said earnestly. "Young girls - girls under the legal age limit to get themselves fucked - have absolutely no outlet for their sexual passions. All they can do is play with themselves, and many of them are too inhibited or ashamed even to do that. The world is full of little girls like Sarah, desperate for some man to grab hold of them and take what they're too shy to offer. That's why they fantasise about rape. For most of them, rape is their only chance of getting what they want. Sarah is very lucky, in that respect. She's being given an opportunity that a lot of girls never get, or only get much later in life."

This disingenuous speech did its job. Mr. Harper seemed a lot happier now, and we proceeded to the matter in hand. And for starters, I suggested that we should introduce Sarah to the concept of fellatio and make her suck us both off. Mr. Harper agreed very eagerly.

I told Sarah to sit up, and helped her to do so. She was still a little dazed and dishevelled from the very brutal sexual abuse she'd already received, and she still had her hands clasped to her raw and mangled pussy. She looked very scared and unhappy as I explained to her the next stage of her sexual awakening.

"You're probably too young to remember this, Sarah," I said, lapsing into my gentle schoolteacher voice again, "but when you were a very little girl, a baby, you used to suck on your mummy's tits and get milk out of them. Well now you're going to suck on your daddy's cock in the same way, and if he gets very excited then he'll shoot his milk into your mouth in very much the same way. It's a lovely and natural thing, and a very nice way to show your daddy how much you love him."

Sarah's face was a picture. She certainly hadn't forgotten how I'd fucked her face the week before, and she had a pretty good idea what drinking daddy's milk might entail. But she was completely in our power, and like a good little girl she opened her mouth and accepted her father's hard-on, which Mr. Harper eagerly shoved between her lips. He gave a groan of delight as his knob slid into his little girl's twelve-year-old mouth. If he had had any doubts about taking Sarah's sexual education further, they disappeared now.

I coached Sarah in how to suck and lick on her daddy's big prong, and how to wank it with her hand at the same time. "And get plenty of saliva in your mouth, Sarah," I told her. "If your mouth is dry, it won't feel so good for your daddy as you work your head up and down on his cock. That's it. Good girl. Good girl."

Sarah sucked and bobbed and wanked like a pre-teen whore, and Mr. Harper moaned and gasped in ecstasy as the angelically beautiful twelve-year-old paid oral worship to his dick.

"Now this is called fellatio," I told Sarah, after a few minutes. "And it's one of the nicest things that a woman, or a little girl like you, can do for a man. But it's not the only way for a girl's mouth to give a man sexual pleasure. It's also possible for the man to fuck the girl's mouth with his cock, just like your daddy fucked your vagina a little while ago. Mr. Harper, could you please demonstrate?"

Mr. Harper didn't need to be asked twice. It was obvious that he'd been holding himself back with great difficulty. Now he began to pump his thick shaft in and out of Sarah's mouth, gently at first but then with increasing urgency and insistence. Sarah's eyes went big and wide. She breathed through her nose, shallowly and tremulously, as her mouth was put to use as a sexual orifice.

"This has a different name, Sarah," I told her. "It's irrumatio. But most people would just say that you're taking it in the face, or getting your face fucked."

And she certainly was! Mr. Harper had his hand on the back of the little girl's head now, holding her in place while he drove more than half his length into Sarah's sweet mouth. Every so often she gagged a little, when the broad head of his cock invaded her throat, and he apologised each time, but he didn't stop shagging her pretty face. He was getting really worked up, and I guessed that he was close to another orgasm.

"And pause," I said, quietly.

Panting and red-faced, Mr. Harper reluctantly withdrew. Sarah swallowed hard, trembling, her breathing very ragged.

"That was wonderful, Sarah," I assured her. "You gave your daddy a lot of pleasure, and I think he'll be ejaculating in your mouth very soon. But first, I want you to experience something a little different, and even more exciting. Kneel on the bed - that's right, hands and knees. Push your bum out towards your daddy. There you go. Mr. Harper, if you'd like to kneel behind Sarah."

We got into position, Mr. Harper behind Sarah and me in front of her.

"Now this," I said, staring down into the twelve-year-old's limpid, terrified eyes, "is called a threesome."

I shoved my cock unceremoniously into her mouth and started to hump it. At the same time, Mr. Harper, boiling over with lust after experiencing the delights of Sarah's lips and tongue, shoved his prick up her cunt and started to give her a very vigorous seeing-to from behind.

Poor Sarah! We were kicking the abuse up to a whole new level, now, and she almost collapsed as our two enormous adult cocks invaded and battered her young body. I was deliberately pushing my hard-on as far into her throat as it would go, revelling in the gagging sounds she made every time my glans slid past her tonsils. And Mr. Harper, unable to hold back, was pounding away at her immature cunt with reckless disregard for her interior anatomy.

We screwed her like this for perhaps ten minutes, panting and gasping with pleasure while Sarah choked and shuddered between us. Every now and then, she managed a hapless, pleading moan.

"Those are moans of sexual pleasure," I assured Mr. Harper. "Sarah is loving this."

It was a preposterous assertion, but I wanted him to feel good about what we were doing. And more importantly, I didn't want him to change his mind about this before I'd blown my load.

"Do you want to come in Sarah's mouth?" I panted.

Mr. Harper looked excited, ashamed, eager, afraid. "I… Yes! I really do!" he blurted at last.

"Me too," I agreed. "But I want to have another go up that lovely little cunt first. Let's change ends."

Mr. Harper readily complied, seeming untroubled at that moment that his beautiful little girl had become no more than a set of interchangeable orifices - a living sex toy for two eager paedophiles.

We both pulled out of Sarah, who slid down onto the bed, so dazed from the rough fucking that she was only half-conscious. We repositioned ourselves, but didn't bother this time to get her kneeling. Mr. Harper tilted her head back and fed her his dick from the side.

I raised her right leg, pushing her knee up against her tit to expose her obscenely gaping vagina. I took a moment to admire the view. It delighted me that Sarah's tiny hole stayed open like this after it had been fucked, the muscles too stretched and tortured to pull it closed again.

With a thrill of pleasure, I entered the little girl's cunt for the second time. To my delight, the angle permitted even better access than before. This time, with a little determination, I was able to get all ten inches of my massively erect cock up into that tiny defenceless hole. My knob pressed hard against a spongy barrier that held… held… and then finally yielded very suddenly. I was fucking Sarah in her immature womb! Utterly thrilled, I shifted my weight to bear down on her all the harder. Forget her mouth! This was where my load was going!

Mr. Harper, meanwhile, was making passionate love to the little girl's face, grunting like a pig as he thrust his dick down her throat. Sarah's hands were making little fluttering motion, but there was nothing she could do, no way she could escape our lustful attentions as we vigorously raped her at both ends.

"Oh Jesus!" Mr. Harper groaned suddenly. "I'm going to come! I'm going to… guuuuuh!"

He slumped over Sarah, shuddering, and her throat worked convulsively as she struggled to cope with the flood of ejaculate that was squirting from his knob-end into her gullet.

"Swallow it!" Mr. Harper was gasping. "Swallow it, Sarah! Oh shit! Oh Jesus Christ!" But there was just too much cum. It filled the twelve-year-old's mouth, and leaked from the corner of her lips as she gagged and gulped and swallowed.

The sexy sight and erotic sounds sent me over. With a grunt of pure delight, I climaxed, hosing Sarah's womb with gout after gout of sperm even as I continued to ram my cock in and out of her. I wondered if it was her fertile time of the month. It might not even matter, of course, depending on how badly our phallic battering rams had fucked up her internal plumbing. Getting pregnant might be something that Sarah didn't need to worry about in future.

Mr. Harper had slumped back onto the bed by this time, his cock slipping from her lips. So I pulled my dick out of Sarah's cunthole and scaled her body to wank the last few drops of my semen directly onto her dazed face, where it joined the spunk now oozing freely down her chin.

"And that, Sarah," I panted, leering down at her as I masturbated over her, "is passion."

The rest of the lesson was something of an anticlimax after that. Sarah licked our cocks clean, and then we I cleaned her face with a flannel, dressed her, and got her back into some sort of state to be seen. It was a patch-up at best. The little girl's lips were swollen from the mouth-fucking she'd received and she was limping visibly, wincing with every step at the twinges of pain from her badly battered cunt. Mr. Harper was a little worried about what his wife would say when she was Sarah's state, but I suggested some obvious explanations. They had stopped for lunch, and Sarah had had a mild allergic reaction to the salad dressing. And she'd fallen off the piano stool and hurt her lower back. It was a lot more plausible, after all, than that her father and her teacher had just raped the shit out of her. Mrs. Harper was a suspicious cow, but I didn't think she'd suspect that.

"Same time next week," I said as they left.

Sarah gave an involuntary whimper.

"Or perhaps a little earlier," I mused. "It's probably time Sarah learned that her bum is good for other things besides sitting on."

"I'll be here at 10.00am," Mr. Harper promised with alacrity.

That meant cancelling another student, pissing off her parents and losing out on the lesson fee, but I was smiling as I picked up the phone. Sex with Sarah was worth a little inconvenience - and I was determined to make next week's lesson the most memorable yet.
