Option 3: Papers and pens and potions, oh my

It was a minor miracle that she had the restraint to stop at that, so they could...

...tick off all the other requirements on Hermione's shopping list. Fortunately, it seemed that they'd only need to make two more stops to gather the compulsory items; first to get her writing supplies and books, and then to get the brewing equipment for potions. "Trust me," Rose told her, as they slipped past a gaggle of dazed-looking students and into Flourish & THOTs, the brunette pouting that she didn't get a good look at the ink covering their bodies, "you'll be glad we did it in this order." Rose easily found them a path through the crowd, primarily by weaving as close as possible to wizards who already had their hands full and their cocks sheathed inside someone, and the pair reached the front of the line with only light blushes and a handful of bright red handprints to show for it. The cashiers, a trio of glassy-eyed blondes that Hermione mentally dubbed Left, Middle and Right, smiled for them and beckoned them closer.

"Hi there, Rose," Middle waved, "here to get your friend drained?" Hermione raised an eyebrow as she cocked her hip to give a passing man a better grip to feel how juicy her ass was, although he didn't seem particularly interested in fucking her right now. Perhaps he's not sure if he can afford me, she thought to herself, unsure why the thought of a man not bending her over in the middle of a crowded shop was so offensive to her, I need to advertise myself better if I'm going to be a whore. "Drained," she asked, the odd question snapping her back to reality, "what do you mean by that?" Middle motioned for Left to continue as one of the male customers slipped behind the counter, flipped up her skirt and sank balls-deep into her pussy, forcing her to focus on throwing her hips back for him.

The second blonde gave her a practiced smile and handed her a book, a quick flip through showing it was totally blank. "Ministry policy is that all muggleborn students should start at the same level of knowledge on magic," she explained, "so as not to give people who got their school supplies early any advantage over their peers." No mention of people with magic in the family already, Hermione mused, not sure why I expected anything different, honestly. "If you just take a look down at the book I gave you-" Hermione, metaphorically cursed with an insatiable curiosity, couldn't stop herself doing just that - and so she got a perfect view of a pair of glowing pink lips sprouting from the cover and opening wide in a silent moan.

She tried to look away, to put the book down, to open her mouth and say something, but all that came out was a long, low moan - the kind those lips looked like they should have been making - as she felt a sucking sensation inside her mind. She shuddered in place while the book went to work, greedily 'eyeing' every letter she'd read and syllable she'd heard on the theoretical and practical sides of magic; and, thanks to that aforementioned curse of curiosity, there was a lot for it to gorge itself on. Dozens of thin ribbons of pink light sprouted from the cover, winding their way up her arms like serpents, their tips probing and 'tasting' her flesh as they went. Up, up, up her biceps, around her neck, and slowly along her jawline - before they formed two clusters, one on each side of her head, and wove themselves together into thick, ragged-ended ropes.

SCHLOP!

"Nngh!" The sound **** its way out through gritted teeth as the ethereal tentacles plunged into her ears. "G-Guh! Hnnngh..." A loud gulping sound, like someone swallowing a particularly thick milkshake, filled her thoughts and left a noticeable blank spot in its wake as a fat bulge started to travel down each appendage. Gulp, gulp, gulp, GULP; the only thing Hermione could do was shiver and let out meaningless, **** noises as every scrap of her 'unfair' knowledge was sucked from her brain. The book swelled with every bulge that reached the end of its journey, visibly throbbing in Hermione's hands like a massive heart, until the last one was sucked inside. There was a moment of stillness before the book seemed to clench, the tentacles thickened as something rushed down them and Hermione moaned just like she had before while her eyes crossed, her tongue lolled out and a small waterfall of drool poured into her cleavage.

SCHURP!

"-and we'll have you back to basics in no time," the cashier finished while the tentacles and lips winked out of existence, clearly having rehearsed the timing. "Don't worry," she 'reassured' Hermione, "even if there was a little bit of collateral damage, our books always fill you back up with something useful." The brunette opened and closed her mouth a couple of times, working her jaw and making her ears pop as she tried to piece together what was missing. Still remember my family, still know how to read and- She grabbed a quill and wrote 'I'M A MUDBLOOD WHORE' on the back of the opposite forearm. -write, so that's fine. No memories of what I read in Hogwarts: A History even though I remember reading it, no memories of what leaflets I asked Professor Vector for even though I remember I have them at home... And no memories of A-Level physics either even though I remember getting an A*.

She blinked as a pair of quill-tips tickled the skin of her asscheeks.

I'm a witch, I'm a whore, I'm not a proper lady, she recited to herself, reassured by the mantra. What the hell, I don't need physics, it probably breaks down the moment someone picks up a wand anyway. She looked at the middle blonde, the one that had first greeted Rose, looked at the queue forming as her mid-fuck work rate slowed to a crawl, and sighed in exasperation. "Honestly, if you can't work with your holes stuffed," she admonished the girl, sashaying around behind the man using her and dropping into a squat, "you shouldn't work in retail." With that, she tugged down on his belt and pressed her face to his ass, tongue wiggling into him and twirling around as she delivered a rimjob with a level of skill neither of them expected. She pulled back after a moment with a wet, sloppy smack of her lips as he began to unload into the cashier and stood up. "Thank you," she smiled at the one who'd overseen her draining, lifting her chin to let one of the floating quills write 'RIMJOB DISPENSER' around her throat like a collar, "that is useful."

Fortunately for their backs, the regulations about muggleborns having the minimum exposure to magical knowledge possible prior to their arrival at Hogwarts meant that the catalogue of textbooks they were expected to buy would be delivered to their rooms there instead. Now that the disorientation - and, if she was being honest with herself, slight high - of getting her brain drained had worn off, Hermione was suddenly feeling rather more conscious of the writing left all over her by the enchanted quills. Not in a bad way, though; for a start, the acres of bare skin left by her uniform meant that it was easy for a whore like her to advertise. In addition to the words around her neck and on her left forearm, her prices - '1 GALLEON FOR ORAL SERVICE' and '10 GALLEONS FOR FULL SERVICE' - were written on the upper curves of her breasts, angled in such a way that anyone who wanted to check would have to stare straight at her cleavage, while 'SLAP ME' and 'GROPE ME' adorned her asscheeks to go with her prominent 'ANAL ADDICT' tramp stamp. Her right forearm, written after the very welcome discovery that she was now ambidextrous as well as a top-class ass-eater, bore the proud proclamation 'I ALWAYS SWALLOW'.

Rose had persuaded her that, until she got something permanent, the spot above her pussy should remain unmarked, so they'd left Flourish & THOTs a little earlier than planned. She was pleased to see she was getting plenty of attention as they strutted towards the apothecary, especially the men who took a good, long look at her chest while they grabbed her rear. She'd been a little disappointed that only two of them had chosen to make use of her on the short walk between the shops, and that they'd only used her mouth, but Rose had reassured her that most people were simply in a hurry. "Besides," she told Hermione as the latter sucked the last few drops of cum from her fingers and reached for the handle for the apothecary's door, "you'll have a whole castle full of clients with fat wallets and fatter balls in a couple of months."

Both girls’ nostrils flared as Hermione pushed the door open and the thick, heady aroma of the shop rolled over them, not noticing the vapid giggles spilling from their lips while they stepped inside. “Don’t worry about ingredients today,” Rose drawled, already rubbing her thighs together as she basked in the warm, pussy-dampening feeling brought on by the airborne cocktail of scents, “first years get theirs supplied for them.” Hermione, not being as desensitised as Rose, simply nodded and licked her suddenly-tingling lips, the smell so thick in the air that she could taste it. Surprised at how sure-footed she was in her platform heels, she made her way over to the racks of heavy pewter cauldrons on the wall opposite the counter, lifting one and carrying to where Rose and the cashier were already chatting like old friends.

“Miss Potter has already told me she’s covering your bill,” he told her as Rose got down in front of him - squatting like a whore should, Hermione’s brain ‘helpfully’ informed her as the tingling spread through her whole body - and fished his cock out, “but you’re going to have to attune it yourself. Just take it into the back room, fill it up and drink it dry.” He laughed at her quizzical expression before she could even open her mouth and ask what he meant. “Trust me, it’ll be really obvious once you’re in there, even for a ditz like you. Now, get going.” Hermione’s mouth, having opened to protest him calling her a ditz, clicked shut as she spun around and strode through the doorway into the back of the shop. She couldn’t put her finger on it, but something in his voice - or possibly in the air - just made her cunt clench and put an extra wiggle of her hips into every step.

The door clicked shut behind her, barely noticed, as she stepped into the room that seemed to be the source of all the most intoxicating parts of the shop’s smell. Her head swam as she looked around the small booth, taking in but not truly comprehending the obscene notes scrawled on the walls, feeling a gnawing hunger begin to take root at the sight of the large, pitch black openings in each wall in front of her. The tip of her tongue traced over her lips again as she looked up and saw, in blocky letters, the words ‘announce yourself to begin’ on the wall in front of her. “I’m Hermione Jean Granger,” she said confidently, remembering how important it was to advertise herself, “and I’m going to be the best mudblood whore Hogwarts has ever seen!” She set the cauldron down heavily in the middle of the floor as a trio of fat, veiny cocks - bigger than any she’d taken up her ass in the Leaky Cauldron or either of her first proper clients - slid out of the inky blackness and throbbed as they waited for her attention.

She got to work immediately, squatting in front of her cauldron and reaching up to deliver silky-soft handjobs to each of the shafts on either side of her as she wrapped her lips around the third. She slurped and sucked her way down to the base while her tongue softly traced every prominent vein, before backing off with a sigh of satisfaction and swapping her mouth for a hand as she got to work on each of the others in turn. Before long, her sloppy sucking and spit-slicked stroking had all three ready to pop, and she shifted herself out of the way just in time for them to unload a barrage of pencil-thick ropes of cum, every drop that passed over the open top of her cauldron being instantly sucked down into it. The human - presumably - shafts withdrew and were immediately replaced, these ones slightly larger and sporting faintly-defined ridges all the way down their length. Hermione looked at her cauldron, clearly needing much, much more for it to be even remotely full, and got back to work.

Over the next few minutes - or hour, or hours - she serviced dozens of ‘customers’; planting sloppy kisses of werewolves’ fat knots, teasing the leaking cumslits of centaurs’ flared heads with her tongue, stroking trolls’ throbbing holesplitters with her thick thighs and thong-clad lower lips, and then repeating the process for a bewildering - to her addled mind, at least - array of combinations. Finally, while the grey-skinned pillar of meat pulsing against her cunt sent her into a moaning, hip-bucking orgasm of her own, she drained the last troll into her cauldron and dropped to her knees as the slab of meat holding her upright vanished. She giggled at the sight of it, full to the brim of tar-thick, visibly steaming cockslop; it would have been downright intimidating if her mind hadn’t been so drenched in dopamine from her second - though rather less direct - exposure to centaur fuckfumes, but all she could think of was how tasty it looked.

Arms burning with the effort of lifting it, she carefully raised the cauldron off the ground, brought the rim to her lips and tilted it just enough to flood her mouth before lowering it again. Her posture practically melted as the taste exploded on her tongue, the dexterous muscle swishing the cheek-bulging load around her mouth as best she could with how thick it was. Eyelashes fluttering and body trembling with bliss, she swallowed half, then two thirds of it, relishing the heavy, oozing passage of it down her gullet as she threw back her head and noisily gargled the ‘merely’ mouth-filling remainder. Gulping that down as well, she lifted the cauldron and repeated the process again and again, the mouthfuls growing more and more frequent until she was chugging the delicious, thought-melting ‘brew’ without pause. When the cauldron finally emptied, she let out a long sigh of satisfaction, pleased to note the pristine emptiness of the cauldron and the fact that she hadn’t spilled a drop.

It took her what felt like an age to get back on her feet, her movements flowing even more smoothly than before and her abdomen curiously lacking the prominent cum-belly that so much ballbatter should have induced. The effects of the centaur spunk fizzed and popped inside her brain, every complex thought as hot and sticky as the troll cum that she'd just chugged. She stared at the clock above the door for a few moments, her mind taking rather longer than normal to read the hands rather than the kaleidoscopic pattern on the face, then giggled happily as she grabbed the quill that popped into existence in front of her and scrawled her name and time on side of her cauldron. Swaying tipsily as she went, she made her way back to the counter and planted her purchase firmly on it; the cashier just slumped in his chair and groaned dazedly as Rose lapped the last drop of cum from his rapidly-softening dick. "Think I might have been a bit too enthusiastic," she smirked as she stood up. "You done already? I'm impressed."

Hermione just nodded and grinned, not trusting her mouth to properly form words through the warm numbness that had overtaken it. Rose just shook her head and dropped the delivery fee into the her cauldron before leading her back outside. Even having finished surprisingly quickly, it was getting late enough in the day that they only had time to...

Option 1: ...head to Gringotts to open a student account. Lily and Rose are perfectly willing to cover Hermione's costs, but she still deserves a chance to receive an, ah, 'injection of seed capital' from the Goblins. (Lily will continue being used as a sex **** until they arrive at Hogwarts, with unknown consequences.)

Option 2: ...take a trip into Carn Alley to fetch Professor Potter. Just because it was her turn to be used as a sex ****, didn't mean she could stay there indefinitely - especially not so close to the start of the school year! (Without anyone else to split their attention, one randomly-selected girl in the same year as Rose and Hermione will arrive at Hogwarts as a Goblin-owned broodmare.)

Option 3: ...say their goodbyes and head home, though not before Rose gave Hermione directions for how to reach the platform for the Express. (Time skip to the Hogwarts Express, both of the above consequences will happen.)

AN: I am, as always, happy to take suggestions on the consequences for Lily or which 'lucky' girl got the full Gringotts gangbang experience.
