Note: This story was dynamically reformatted for online reading convenience. Hermione spent most of that day being used by Harry Potter. Luckily, it was a Sunday, so they weren -(TM)t needed in class and could spend hours and hours rutting like beasts. Hermione was fucked in all of her holes until they were raw, covered inside and out with torrents of spunk. Harry had made good use of the room, including tying her to the cross and lashing her tits and cunt with a leather strap. Hermione had come hard with every direct hit on her pussy. Eventually, Harry had grown tired of using the whore and muttered something about finding his cumdump girlfriend. He blasted on final wave of cum down Hermione -(TM)s throat as he said this before withdrawing and walking out of the room without a backward glance. Hermione was left breathless on the floor, dripping cum onto the flagstones. After a few minutes of lying in a cum dazed stupor, Hermione gathered her wits and looked around. She was alone in the Room. Various fluids and toys covered the floor, and next to her on the floor was -- the book. Which definitely had not been there before. -Clingy little thing, aren -(TM)t you? - she said, picking up the book and feeling the charge from it shoot straight to her clit. She opened the covers and flicked through, not really reading it, just hoping that something would leap out at her. Something did. The book seemed to stop of its own volition at a page titled -~Companion Summoning -(TM). It seemed to detail several spells that would summon forth different creatures for the caster to spend some quality time with. One spell in particular seemed to call out to Hermione, and without quite realising what she was doing she pulled her wand from her ass (long since shoved there by Harry) and tapped the book with it, intoning the words of the spell. Instantly, the book started to shake. Hermione gasped and dropped it to the floor before clambering to her feet and backing away. A black spot seemed to be spreading from the centre of the book, slowly taking over the pages until the entire book was nothing but a black hole in space. Suddenly, something shot out of the book. A purple tentacle, thick and smooth and slimy looking. It rose up in the air, it -(TM)s head moving cautiously, seeming to probe the air. Hermione thought it was probably looking for her. She was scared now, cursing her own foolishness. She had no idea what sort of potentially deadly beast she had called from the book. She raised her wand and pointed it towards the tentacle, ready to defend herself. Instantly, the tentacle whipped it -(TM)s head around to face her and shot forward. Before she could react, the slimy limb wrapped itself around her wrist and twisted, sending a bolt of pain up her arm and her wand clattering to the floor. Hermione used her free hand to claw at the restraining tentacle, but she couldn -(TM)t get a grip on the slimy surface. She was so distracted by this that she failed to notice another three identical tentacles emerging from the book and snaking their way towards her until it was too late. They quickly lashed towards her and constrained her other limbs, sliding up and around until they held her securely, her arms and legs spread wide open. The tendrils flexed and lifted Hermione from the ground, carrying her back towards the book until she was suspended face down above it, her enhanced tits hanging down impressively. The beast had apparently noticed them as well, as the tentacles wrapped around her arms extended further, slowly circling her beautiful breasts. The slimy things continued until her tits were constrained by several loops of tentacle, which quickly got to work squeezing and massaging, sending pleasure shooting to her brain and overheated pussy. She moaned despite herself. As if called forth by her moan, a new tentacle emerged from the portal below her. While those holding her aloft were a couple of inches thick, this one looked much larger, as thick as her wrist at its smallest point. She gulped, imagining just where the creature planned to stick that, once more silently thanking her past self for the permanent stretching charm. The new arrival extended upwards toward her until the tip brushed against her face. Hermione opened her lips, fully expecting the creature to force its way down her throat. The tentacle did make a few token thrusts into her mouth, but barely pushed into her throat before withdrawing. The slimy thing dragged itself down her neck, down between her tits, now filled with pleasure and pain in equal measure, and briefly poked at her belly-button before reaching her dripping sex. Hermione was glad she had practiced so much with Harry -(TM)s ridiculous cock to help her take this invader and braced herself for the penetration. The tentacle had other ideas though, and moved past her cunt to poke at her back entrance. Hermione gasped, and tried to relax her entrance. Stretching charm or not, this was going to be tough. The tip of the tendril pushed and prodded until her asshole stretched to let it in, and it quickly took the opportunity to explore further, soon shoving at least a foot of thick, slimy tentacle into Hermione -(TM)s ass. Hermione groaned in pain and pleasure. The slime seemed to be lubricating the passage, and her asshole had already been expanded today by Harry, but it was still an awfully big intruder. She decided to see it as a challenge. Just how much of this massive tentacle could she take? The creature seemed to be thinking along similar lines as it sent more and more of itself out of the book and into her asshole. She could feel it squirming inside her, worming it -(TM)s way up and through her guts. It felt strange, not painful or pleasurable (her asshole and tits were providing enough of both at this point) but the motion and the knowledge that she was becoming stuffed with a monstrous phallus was deeply erotic to her whore brain. She hoped the tentacle would make it to her stomach and out of her mouth. She could picture it, picture her completely penetrated by this thing. Her pussy spasmed and she moaned hard as she came at the image, squirting girl-cum onto the tentacle below. Again, as if in reaction to her cries, more of the purple tentacles rose out of the book below. These were all extremely thin, thinner than pencils, and there were many of them. Two rose up to her extended nipples and started whipping until her nips were aflame with pain and hard as diamonds. Several tendrils surrounded her face, and Hermione stared at them apprehensively, suddenly worried again about the beast -(TM)s plan. Her fears were confirmed when two of the tentacles climbed towards her nose and started inching up into her nostrils. The pain was intense, the sensation not remotely pleasurable as the tiny shafts wiggled further into her head. She was momentarily distracted from the nasal invasion when she felt the main tentacle enter her stomach. She couldn -(TM)t see, but her belly now hung below her, stretched and full of the great length of tentacle filling her guts. Her asshole was stretched wide now, the tentacle as thick as a bludger where it met her ring. The head paused briefly in her stomach, seemingly waiting for something. Hermione -(TM)s attention was brought back to the smaller tendrils when she felt two of them poking at her ears. Her eyes widened as she realised the monster -(TM)s plan. This was impossible! The creature would kill her if it fucked her ears! She started to thrash around as best she could, but the beast pushed its tiny tendrils into her ear canals. It was strangely pleasurable, until the tentacles seemed to come up against an obstruction. Hermione hoped desperately that they would get the message and back off, but after a second -(TM)s pause they pushed on. Hermione -(TM)s eyes widened in shock and pain as the invaders punched through. She could feel them inside her head! Inside her brain! The tentacles were in her brain! She thrashed wildly as she felt them moving around, almost stirring up her brains, until -- Hermione stopped. She felt amazing. The tentacles in her brain didn -(TM)t worry her anymore, she knew that they were there to help her. The pain in her ears and nose vanished, replaced by wondrous pleasure. Her stretched asshole and abused breasts no longer ached, again feeling only pleasure. She sighed with orgasmic delight as she came again, squirting onto the mass of tendrils below. Some part of her knew that she should be worried that the tentacles had somehow rewired her brain, but she felt so fucking good that she didn -(TM)t care. The central tentacle decided to start moving again, and Hermione could feel it start to press against her esophagus. She knew this was it, this was where she would be penetrated more completely than she had thought possible. She could feel the thick presence moving up her throat, slowly stretching her as it moved. Her ear tentacles continued to pump in and out of her brain, and she felt a tickle as the nostril tendrils worked through her nose and emerged in her throat. The two tiny invaders moved back up her throat and into her mouth. She wiggled her tongue as they slid over it, almost kissing them, but was ignored as they moved past her lips. The tentacles hooked around her plump lips and forced them wide open, fixing her mouth in an -~O -(TM) shape, clearly in preparation for the main event, which had nearly reached her mouth now. Hermione felt a new sensation as the tentacles whipping her tits suddenly changed course and started pressing against the tips of her nipples. Apparently the monster, not content with plugging every orifice she had, wanted to make some new ones. She felt intense pressure which was suddenly relieved when her nipples somehow opened up and allowed the tentacles to penetrate them. Hermione -(TM)s eyes shot open at the previously unimagined sensation of having her nipples fucked. The tendrils slid sensually into her nipples, into her expanded tits, and started thrusting back and forth slowly. It was probably just the mind-rape talking, but it felt as good as any cunt-fucking she had taken. Hermione couldn -(TM)t think, her tentacle-fucked brain now only registering pleasure, sparks flying in her head with every thrust into her ears and tits, every movement in her nose and throat. Her eyes rolled back in her head and her tongue hung out of her mouth, drool running down her chin. She was more filled than she had ever been before - but her cunt remained empty. What was left of her mind waited eagerly for the monster to finally fix that. The main tentacle forced its way out of Hermione -(TM)s throat and into her mouth, before quickly thrusting further, spearing out between her lips, still spread wide by the noses tendrils. She was filled utterly, penetrated completely by the long tentacle from ass to mouth. And still it wasn -(TM)t done. The thick limb slid further out of her mouth, sliding down her chin and down between her tits. Her nipple rapists picked up the pace at this, sending her boobs shaking back and forth as they too were deeply penetrated. The tentacle traveled down, over her engorged belly, before finally reaching her pussy. It flicked at her clit, sending another instant orgasm shooting through her body. She moaned thickly around the magical flesh filling her mouth as her monstrous lover finally entered her cunt. It felt amazing, as if everything prior was merely foreplay. The tentacle slowly forced its way further in until it reached her the entrance to her womb, sending another shock of pain turned pleasure to her fevered brain. The tentacle battered against her cervix until it was allowed entrance, shooting straight into her womb until she was completely filled. Her stomach bulged further as the tentacle forced itself as far in as it could go. This was it. There was nowhere left to go. Her ass, her mouth, her nose, her ears, ever her nipples, and now her womb, her most sacred place, were all being fucked completely by the monstrous invader. And now she could sense a climax approaching. Bulges appeared in some of the tentacles, traveling rapidly up towards her dangling, exhausted form. A huge shape forced itself against her asshole and quickly moved inside. She could feel it traveling up inside her body. Many smaller bulges traveled up towards her nipples and started forcing their way inside her breasts. She could feel small spherical shapes being deposited inside her tits. The remnants of her shattered mind knew that they must be eggs, and knew that she should be worried, but the sensation felt so powerfully erotic that she just didn -(TM)t care. The large egg reached her stomach and soon forced its way up her throat and into her mouth, filling it to capacity. Her nose tendrils stretched her mouth wide open, wider than she had thought possible, to allow the bulge out from between her lips. The egg traveled down her front between her breasts, still swelling with many, many eggs. Already expanded, they were now almost the size of her head. The large egg reached her pussy and pushed inside and into her womb, before finally being spat out. The egg alone stretched her womb hugely, and she came again at the knowledge that she had been impregnated by the alien beast. Eggs stopped shooting into her tits, and just as she thought it was over, liquid came spewing out of every tentacle at once. Her tits swelled further and plumped up, covering the lumps left by the eggs. Her belly swelled until she looked nine months pregnant. Her nose tendrils turned to face her and shot the cum-like fluid straight into her eyes, as more of the stuff shot out of her ears as her head was filled with liquid. After a minute of this, her monstrous lover stopped fertilizing her every orifice. The main tentacle suddenly pulled out of her cunt, rapidly withdrawing back into her mouth. Within minutes, it had finished it -(TM)s retreat, at last leaving her gaping asshole. The other tentacles withdrew from her nipples, nose and ears, and those wrapped around her limbs lowered her gently to the floor. Out of the corner of her eye, she saw the creature retreat back inside the black portal, which slammed shut as it returned to book form. Hermione was left panting on the floor, again. Cum leaked from her ears, her nose, even her tear ducts. Her breasts were swollen beyond recognition, cum dripping from her nipples like milk. Her belly still looked massively pregnant, and she knew that it would remain so until her purpose was fulfilled and she gave birth to the creature now living inside of her. She couldn -(TM)t wait.
