Option X: Harry and the Debauched, Obscene, No Shame, Very Lewd Night

Unlike the majority of his peers and elders, Harry Potter was decidedly not enjoying himself at his first Hogwarts welcoming feast. With his mother constantly bouncing between every late night working, social event, girls' holidays with his sister, and other sundry excuses to leave the house that she could muster - slobbering on the cocks of friends, acquaintances and strangers the whole time, as she made the most of being away from her husband - it was perhaps inevitable that his father's influence over him was greater than she'd have preferred. James Potter's foibles - petty possessiveness over his wife, insecurity about his lacklustre sexual abilities, deep-seated belief that Armando Dippet and Albus Dumbledore probably had the right idea, and lingering resentment of all sorts of people who'd been able to weather the collapse of prudist influence far better than he had - may not have been genetic, but he'd still been able to pass a fittingly watered-down version of his outlook on life to his son.

He took a drink from his goblet, and hiccupped silently.

Did James realise that he was dooming Harry to the life of a hopeless cuckold? Probably not, but that's neither here nor there - Harry was woefully ill-equipped to make it in a free-use society, and that was all that mattered. Case in point, he was already feeling mightily insecure about how he was the only newly-assigned Gryffindor not currently balls-deep in a hot, wet, welcoming hole belonging to one of his Greedywhore counterparts. Even Ron, who'd done an admirable job trying to keep his friend distracted with small talk as the dark-haired young man internally fretted over how much smaller he was than everyone else where it counted, had succumbed to the spreading debauchery, currently stifling his groans of pleasure as an unseen 'assailant' noisily attempted to suck the life out of him under the table like some kind of cumpire.

He took another, hiccupped quietly, and wondered why his body was tingling.

He consoled himself that, regardless of what Ginny might be getting up to, he hadn't seen his crush involved in anything more than some heavy petting before he'd lost sight of her entirely. He doubly consoled himself with the knowledge that, among the vanishing small number of people, male or female, not to be caught up in the debauchery, he could see that his mother and sister were thus far unsullied. In fact, he both envied and decidedly didn't envy Rose right now - envied her for her ability to act totally unperturbed as she... as she... did something innocuous, and didn't envy having to keep up the act when one of their fellow new arrivals was literally whoring herself out right beside her. He couldn't tell whether it was the brunette's obscene behaviour or her deliriously excited expression as she jerked a pair of older students off all over the pile of gold she'd amassed already that made his gut twist nervously, and he was pretty sure he didn't want to be able to tell.

He took another drink, hiccupped, and wondered why he felt so hot all of a sudden.

He filed that one away right beside the uncomfortable truth that watching girls getting railed by cocks so much bigger than him that it was impossible to picture himself in their place got him harder than he'd ever been before, and tried to ignore both of them. It was difficult to do, what with the shameless exhibitionism going on all around him and the hot, tight, tingly pounding feeling reverberating through his body. Slowly, the tightness began to concentrate in his abdomen, while the pounding sensation migrated to his chest and hips and his face went numb. He raised his goblet for another drink, head swimming, and felt it bump against something - two somethings, in fact - much sooner than her expected.

"Confundo."

He tried to look down and cross his eyes so he could see what had apparently attached itself to his lips like a pair of bumpers, but only succeeded in making himself look brainless. He felt a sudden, painless twisting sensation in his crotch and abdomen, and suddenly his pants no longer felt quite so uncomfortably tight. There was a creaking sensation as his waist narrowed like it had been cinched into a corset, a feeling of being stretched like taffy as his hips stretched outwards, and the curious sensation of his ass blowing up like a pair of balloons into a bubble butt so thicc and meaty that it raised him a good couple of inches in his seat. Glassy green eyes blinked slowly and looked back up, finding the brunette whore that'd been getting railed next to Rose kneeling in front of him on the table, her clothes in disarray and her whole body covered in cum as she smirked.

"Confundo."

Harry felt the twisting sensation again, and head swam as he tried to remember what she'd been doing, her hands reaching downwards and finding only the pleated folds of a too-short skirt where his trousers had once covered him below the waist. He'd been... She'd been... The brunette abruptly arched her spine and threw her shoulders back, thrusting her chest out towards Harry, then repeated the motion over and over again while her fingers snapped in time. snap Soon Harry's body was burning with the urge to imitate her, and his hands abandoned their exploration of her new sartorial state in preparation. snap It was like a compulsion, like the brunette's big, bouncy bust being thoughtlessly thrust towards her was transmitting some of that bounciness into him. snap Unseen by Harry, and unfelt under the strange twisting feeling, the pathetic dicklet hidden behind his lacy uniform thong suddenly became as hard as it was able to, as if by some imperceptible command. snap Harry squared her shoulders, wiggled his hips, and...

snap

...let out a gasp of delight as the first thrust of his chest lined up perfectly with those of the girl she was copying and her board-flat bust swelled a little bigger.

snap

Bigger, as a uniform jacket shortened abruptly into a bolero style.

snap

Bigger, as a uniform shirt lost its buttons as its cut shifted into a decidedly more feminine one.

snap

Bigger, as Harry's cock - if it could still be called such - inverted with a sudden release of tension into a fat, drooling pussy.

"Confundo."

snap

BIGGER, as the double-whammy of her total transformation and the giddy rush of having her brain scrambled mixed into her first female orgasm, her virgin cunt gushing so hard it soaked her thighs and dripped off of her seat onto the floor. She blinked, and saw her sister slobbering on half a dozen cocks at once, her attention bouncing between them so quickly that none of them had time to feel neglected. A perfectly-manicured (albeit very tacky-looking) fingernail grazed against the soft, sensitive flesh of her new lips as her scrambled brain struggled to come back together, the girthy, irresistible shaft of Lily Potter's Infidelius charm warping and twisting her mind around it.

Her mother and sister would never act like nasty nympho skanks, but she could see Rose happily gargling a mouthful of hot, sticky jizz before swallowing it all down. Her mother and sister would never be a pair of cheating bitches, but she could see Lily quivering and moaning as her unprotected pussy was filled up with one of Professor Flitwick's potent half-goblin loads. Her mother and sister would never be a pair of greedy cum-addicts, but she could see them both guzzling down babybatter like they were starving. Then, as the brunette sneered at her and spat in her open, slack-jawed mouth, it all clicked into place - it wasn't nasty because this was how women were supposed to behave, it wasn't cheating unless they got caught, and it wasn't an addiction if they really did need all that cum to... to...

"Confundo."

Her mind went blank as a crowd of male students descended on her and the brunette, fingers and lips wrapping around fat, throbbing shafts as they hauled her up onto the table and began to fuck her. She squealed in panic and delight as her virgin holes were stretched taut around invading cocks, shuddering and spilling frothy drool from her plugged-up throat and sticky-sweet juices from her snatch in equal measure, frantically jerking the men in each hand off onto her tits as another used them like her cleavage was nothing but a fleshlight. The three in her holes dumped such hot, thick loads of cum into her that she blacked out for a moment, the intensity of her first creampies being the straw that broke the camel's back after the barrage of potions and spells she'd recently suffered.

Fortunately, the man fucking her tits was kind enough to backhand her back into consciousness, and she barely had time to slur out a delirious 'thank you, Sir' before she was slurping and gagging on his shaft, as the pair that had been warmed up by her handjobs took her pussy and asshole and three more men stepped up for her to 'prepare' for her holes. Three, six, nine, and on and on; she lost track of how many times she'd been pumped full of cum somewhere after the thirty mark, when Ginny had finished sucking Ron senseless and emerged from under the table to share a sloppy, cum-filled kiss with her while they waited for her latest half-dozen partners to vanish the thick layer of cum that their immediate predecessors had coated her in. Then it was back to back-to-back rounds of triple penetration, relentlessly 'training' her overflowing holes until even the brief moments of relative emptiness between 'teams' felt unbearably long.

When she whined and panted for more as she was levitated out of the hall, Rose, Ginny and the brunette whore plugged her holes with their wands and slung insults at her until she came hard around the 'improvised' dildos. She was so addled by the aftershocks of being transformed and taken that she didn't even notice most of the journey, too busy eagerly swapping out the girls' wands for more cocks to care about the times when she wasn't being groped, slapped and used as a living sex toy, her orgasms coming faster and more frequently until she finally slipped into total insensibility and was discarded on an empty bed in favour of a set of toy that writhed and moaned as well as milking whatever man entered on of its holes.

After a long night of being railed into a semi-conscious stupor, what's Hermione doing next morning?

Option 1: Taking advantage of a break between arrival and the start of classes to get to know her new housemates. How are they 'breaking the ice'?

Option 2: Straight to class, hungry for knowledge (among other things). Which Class?

Option 3: On her knees in a wonderful little room Rose recommended to her, ready to earn a few galleons with a nice, quick sucking session. What didn't Rose tell her about the gloryhole booth?

Option 4: Meeting with her head of house, making sure she's settling in alright. What's the real reason Lily called Hermione to her office?

Option X: Something else - or a timeskip, another change of perspective, things like that.

After a barely-less-long night of being railed into an outright **** stupor, what happens to 'Harry'?

Option A: The potion he was slipped to turn him into a busty, bubble butt-packing slut wears off overnight, returning him (at least until someone slips it to him again) to an oblivious, prudish cuckold-to-be.

Option B: The potion he was slipped to turn him into a busty, bubble butt-packing slut wasn't intended to be followed by ingesting such an incredible amount of cum, and the transformation has been made permanent. (Please specify whether something happens to make people oblivious to the change, or if they remember the new girl previously being Harry.)

Option C: The potion he was slipped to turn him into a busty, bubble butt-packing slut wasn't intended to be followed by ingesting such an incredible amount of cum - and so Rose, Hermione, Ginny, or any number of other people have tampered with Harry's return to normalcy. (Please specify the nature of the tampering; timed/triggered cycle of transformation from male to female or female to male, turned into a futa, trapped into a girlish sissy body, beset with mental effects, things of that nature. Non-contradictory changes from different sources are allowed to stack.)

AN: Whew, that took a while. Not sure I'm happy with this chapter, but that might just be because it's my first attempt at a 'proper' TG transformation, never mind one from the victim's PoV - on top of trying to make Harry at least something resembling an actual character, if a shallow one, instead of just a perpetually-outraged prop. Lemme know what you think, drop me a suggestion on what you want to see next, the usual. Also, I'm sorry about the title, but I couldn't resist.
