"God, that shit I just had is unbelievable!"

Padma, waiting impatiently for her sister, Parvati, tapped her foot as she listened to the other girl enthusing about her latest bowel movement. "God, Parvati, you're so crude!" She threw up her hands when she heard the flush of the toilet from behind the locked stall door. "Honestly, do you have to talk about what your colon makes every time you use the loo?"

Parvati emerged from the cubicle with a devious grin on her face, sticking her tongue out before leading Padma to the taps, where she turned the handle and put her hands under the water. "You know, Padma, you have the same sense of humour, as well. Don't deny it."

"Sod off, then," Padma said, feeling her anger at her sister ebb.

"By the way, I saw the way you were looking at Ginny."

"Wha-? I was not!"

"You were, Padma," teased Parvati, drying her hands and turning to her, leaning back against the basin. "You. Like. Her."

"So?" said Padma defensively. "So what if I'm attracted to Ginny Weasley?" Parvati laughed, tapping her hand on the basin as she moved away. "I've seen the way you look at Luna, though."

Parvati turned back and grinned. "And? Are you jealous of my taste in other girls? Anyway, my perfect Prefect, I'd better get to class." Parvati hiked up her skirt as she sauntered toward the door which separated the second floor corridor from the bathroom. The action, deliberate, cold, and calculated, had been utilised by Parvati Patil since time immemorial to drive Padma mad with lust. "Don't tell me you're not tempted," Parvati called out, turning and lowering her skirt with a maniacal smile. "Well, my lovely little sister?"

Padma, the entire triangle between her legs throbbing, growled in sexual frustration as she stormed past her sister. "God, Parvati, you're such an arse!" She stormed in the direction of the Charms classroom, still hearing Parvati's teasing tone, seeing the toned, dark legs and the firm, tight buttocks of her sister as she attempted, vainly, it seemed, to quiet her throbbing, drenched cunny. She felt grateful that her twin had been given fewer than half her classes, though she wondered how long it might last. They were in their sixth year at Hogwarts, and as much as she loved her sister, enjoyed spending her time with the one girl with whom she had any connexion, Padma Patil had found Parvati almost intolerable of late. She behaved much the same in public, but her behaviour in private had become impossible. She could not imagine herself bound to another girl, but sometimes she wondered whether the match might not be one she needed.

"Very nearly late, Ms. Patil," noted Filius Flitwick, whom she found checking his pocket watch as the great bell sounded. "You're normally here earlier."

"I know. I was dealing with an irascible Gryffindor."

"I'd rather you deal with an unruly student and be a bit late. However, we've not enough time for twaddle. Wands out, please!"

Padma focused on Flitwick's Charms lesson as well as she was able, though her mind drifted occasionally to her sister's toned, brown body, and though she made every effort to suppress the tide, Padma found that either she concentrate on her lesson, or else cum, which, given that she had discovered, with Parvati's help, that she was a squirter, would serve only to embarrass her, and would likely lead to expulsion from Hogwarts. "God, I'm... I'm so sorry, Professor," said Padma, going to the bench where she had left her bag and slipping a Puking Pastil into her mouth. "I'm... I'm so..." Padma gagged, feeling the immediate effect of Fred and George Weasley's genius candy, which she had dared not use before, if only for fear that she might abuse it. For theatrical effect more than anything, she allowed a concoction of bile and other stomach contents to slip from between her firmly shut lips.

"Go along to the hospital wing, Ms. Patil. Do come back when you're feeling better." Padma nodded in agreement, soon finding herself out of sight of Professor Flitwick's classroom. She swallowed the antidote end of the Pastil as she marched purposefully in the direction of the library, checking the shelves for Madam Pince before scurrying to the right of the doorway. At the portrait of the short wizard, she whispered the password and slipped quietly through the passage to the fourth floor. Hurrying through the passage and up the short flight to the spiral staircase, she passed another portrait and soon found herself hurrying timidly but urgently toward the clock tower. She mounted the staircase three at a time, flew down the fifth floor corridor, which in that part of the castle mimicked the fourth-floor corridor, and gave the password before bolting into the bathroom. She threw her bag against the wall in the stall at the near end, locked the door with a careless, decisive click, and pulled down her skirt and stockings.

"You fucking wanker, Parvati! Dammit!" She had narrowly avoided flooding her own knickers, a fact she knew that her sister would hardly dread hearing later. Padma sucked in her breath with a hiss as the juices continued to flow from her pussy. "Gar, Parvati Patil, the next time I see you..." she groaned threateningly, knowing that anyone listening would hear only the ecstasy in her voice. "God, if I use either hand, my wand will be drenched... Parvati, you're such a bitch!" Despite her mumblings, Padma touched her damp, throbbing pussy, unable to contain a sharp, hissing intake of breath as the sensation sent shockwaves through her shoulders. She threw back her head and clenched her eyes shut, squeezing her legs together. "Dammit, Parvati..." she moaned.

With practised ease, Padma slipped two fingers into her cunt, driving them up to the knuckle and relishing the sense of aroused elation as she felt the pads of her fingers driving hard against the wall of hard tissue which constituted her G-spot. Pausing for a moment, Padma allowed her body to ache, craving more as she steeled herself for the orgasm she would bring. Taking a few steadying breaths, she pulled her fingers out of her cavity and tasted them, lapping up the sweet nectar her sister had released. "I fucking hate you sometimes, Parvati Patil," Padma whispered, sucking on each delicious finger. She reinserted her fingers, slowly sliding them to the first knuckle, then the second, allowing them to retreat, and penetrating herself a fraction of an inch further with each stroke. With each stroke, Padma increased the pace, the frequency, and the force with which the stroke hit, deliberately avoiding the front wall until the exact moment the pads of her fingers would pass the hard tissue at the front of her cervix, at which point she pressed them firmly against it. Padma could not breathe. With an unusual amount of will, she kept from screaming, and as she pressed her fingers deeper into her cervix, an image of a naked, sprawled Parvati presented itself to her. The image of Parvati splayed its legs slowly, deliberately, and seductively. The image of Parvati was exactly as Padma had seen so many times, though the imaginary twin was so much more... She could not place it.

Parvati's breasts were full, with moderately-sized areolas and large, pointed nipples cresting each; her torso was slender, her waist larger but proportionate to her torso; Parvati's pussy bore signs of their numerous sexual encounter, but her labia did not protrude unfavourably, and her pubic hair grew above her sex, black as a raven, long, though the forest had been tamed; Parvati's smile, despite her mischievousness of late, was soft and inviting, her warm, dark eyes sparkling as she invited a soft kiss from Padma, who longed for her dark twin's full bottom lip.

As she imagined her sister's fingers inside her, Padma found the heat excruciating on her hand. She felt her legs beginning to tremble, her thighs quivering in anticipation of the impending orgasm. "God, God, God..." Padma sat bolt upright, rubbing her clit and, as the orgasm hit, she stopped, pressing the cluster of nerves, relishing the loosening of the muscles in her chest. The fluids rained from within, rushing into the toilet, a practise she had discovered with Parvati's aid only a year or so before. She felt the heat in her face, sighing as her clenched eyes loosened. In her mind, Parvati came with her. Parvati had also learnt that she squirted, but her orgasms were not as spectacular. "Parvati," mumbled Padma, first kissing, then sucking on each delicious finger as the orgasm died. "I love you, Parvati Patil."

The bell tolled as Padma sighed with the final ebbing of her orgasm. "Damn." She picked up her bag, her mind suddenly spinning as she pulled her knickers back into place, having wiped and, to hide the evidence, flushed the toilet. She washed her hands at the tap, retrieving her wand from her bag and doing a thorough check to ascertain the spartan nature of the Prefects' bathroom. "Parvati, sometimes being in love with you isn't worth the trouble."

Padma greeted her sister at dinner, smiling amiably and lowering herself onto the bench beside Parvati. "You know, I had to skive off Charms earlier," she muttered, aware that a few other Gryffindors were nearby. "Want to know why?"

"It couldn't be because of me, could it?" Parvati asked, hiding her smile in a goblet of pumpkin juice. "Padma, you're so gullible. You'll want to learn to control that."

"Yes, because you're so easy to deal with, yourself."

"What're you two on about, then?" asked Ron Weasley, who had been listening. "I'd almost have thought you were taking lessons from Fred and George."

"Sod off, Ron," Padma offered, showing the backs of her index and centre fingers. "This conversaton's not for blokes who refused to dance at the Yule Ball."

"That was two years ago!" Ron said defensively, his mouth filled to bursting with a roll. He swallowed with effort, took a long draught of pumpkin juice, and said, "How much time has to go by before a girl forgives a bloke for something stupid?"

"You mean, how much time has to go by before a girl forgives a bloke for being himself?" Parvati said, raising her eyebrows and smirking mischievously.

"Wha-?"

"It's too late, Ron," Parvati interjected. "You stood Padma up for a dance, and now she'll never forgive you."

Ron blustered excuses until Padma bade her sister goodnight. On the way to the fifth floor, where lay the entrance to the Ravenclaw common room, she saw in the distance the back of a blonde head bobbing away from her. She smiled, feeling her knickers moisten slightly at the thought of Luna's fingers buried in her cunt. She mentally shook herself, her pace quickening as she was caught by the sudden need for company. "Luna!" she called, her heart fluttering as Luna turned to face her. "Hey, Luna."

Luna, though admittedly unusual, was a kind girl, intelligent and thoughtful. Parvati had once quipped to Padma that Luna Lovegood was not unlike a Muggle hippie, whatever that was. Luna was a girl of average height, modest breast, kind eyes, waist-length blonde hair, and an airy voice which augmented her airy manner. "Hello, Padma. It's a nice night, isn't it?"

"It's a lovely night," Padma acceded, indicating the corridor ahead. "Would you like to go for a walk?"

"I'd love to." They spoke as they made their sojourn down the length of the corridor, continuing to converse about the day's lessons as their path took them to the end of the covered bridge which led to the forest. "I hope you don't mind my saying," Luna said as they made their way casually in the direction of Hagrid's hut, "but I overheard some talk earlier about you being distracted and leaving Charms, earlier. May I ask what the trouble was?"

Had it been any other friend, Padma might have been shocked, even defensive, but she found Luna's candour disarming, despite expecting the often surprising observations she made. "Luna, I'm going to tell you something awkward," Padma said slowly. Despite finding Luna attractive, she found in Ginny Weasley something she craved, even something she needed. What was more, if Parvati had her way, and Padma could never deny her most sacred lover what she desired, then Luna Lovegood was unattainable. "You don't have any problem with a girl who's into girls, do you?"

"Why should I have a problem with that?" Luna gazed curiously at Padma. "You aren't confessing your attraction to me, are you?"

"N-no!" Padma withdrew slightly before smiling and shaking her head. "No. I mean, you're attractive. And I would definitely shag you if I had... the..." Padma trailed off, feeling the heat in her face.

Luna flushed, though she held Padma's gaze. "You're attractive, too," Luna confessed. "Though I'm much more attracted to Cho."

"Wha-? You're into Cho?" Padma watched as Luna flushed further crimson. "Anyway, Luna, what I meant to say was, that's not the awkward part, my being attracted to girls." She sighed, knowing that if she divulged her secret to anyone else, she would ultimately find herself ostracised from the rest of the Wizarding World. "Luna, Parvati and I've been in a romantic relationship for nearly three years." The words rushed out, and Padma clapped her hands over her mouth when she finished. "Shit, Luna. Shit. Shit, shit, shit!"

"That's actually a good thing," Luna offered. Padma's eyes widened in shock. She knew that Luna was known for her unusual ideas, but she had never considered that her friend, no matter how wonderful and unusual, would encourage an incestuous relationship. "I think it's wonderful that two people so closely related could share such a connexion. Even though you're in different houses, you're more alike than you are different."

"So, you're not... I mean, you don't think it's...?"

"I've actually always been confused by relationships that weren't incestuous," Luna confessed, continuing toward the forest. Padma kept her pace with the blonde girl. "I don't think those relationships are wrong, I just think there should be a connexion between two lovers."

"Luna, I don't know how to say this," Padma said, her chest tightening in anticipation of her friend's reaction, "but sometimes loony really makes the most sense."
