Chiara entered the Clubhouse feeling refreshed.
The day after the full moon can often be the most nerve racking for the young werewolf. It used to be she’d return to class and feel like everyone was staring at her, wondering if they knew or if someone saw her. But now that she had trusted friends who knew her secret, even if it was only the one friend, she felt better. And having a shower to wash away the dirt under her fingernails or brushing the leaves from her silver hair after waking up on the edge of the forbidden forest was part of her cleansing ritual. Still, she always got nervous walking into the school washrooms. She envied the prefects who got their own private bathroom. More than once she contemplated asking the curse-breaker to let her sneak in after every full moon. (Considering how they’ve been to her, they’d probably be happy to help.)
Now washed and changed into her regular attire, Chiara settled in for a quiet afternoon of studying and reading and being a regular witch and not a werewolf. She came here instead of the Hufflepuff common room because she wanted somewhere peaceful and quiet. She found her textbook which she stowed away a week ago and settled down on the couch to relax in front of the fireplace.
No sooner than she had begun reading when her nose twitched. A scent filled her nostrils and her ears perked up. There was an unspoken side effect to her affliction that came and went. The hours following her transformation could leave her senses temporarily heightened as if she was in her wolf form. Her sense of taste, smell and hearing lingered and occasionally made school work difficult. But in this instance, she detected something curious that brought the young woman up off the couch. She sniffed the air, following her instinct and the scent up the steps. There’s someone here? There was something about the scent that got her attention. She tried to identify it, but the only word that came to mind was…arousal?
Chiara climbed the stairs to the upper level and soon realized she was right. Someone one here. And she could detect their arousal from the stairs because they weren’t alone. She crept up when her ears picked up the moans of a young female voice coming from the sleeping area on the top level of the clubhouse. She kept silent as she walked cautiously and approached the large chamber where a massive bed sat.
Keeping out of sight, she peeked around a column and discovered another student laid out on the bed clutching at the bedsheets, her blonde hair falling over her face while she panted heavily. She gasped in surprise. It was Beatrice Haywood. She was lying on the bed in reverse, her head falling over the end of the mattress. The blue sheets were draped over her body, her top half exposed revealing she was naked, her perky nipples pointing up at the ceiling. She writhed on the bed, moaning and panting, her wide eyes rolling around in their sockets.
What is she doing here, Chiara wondered as she silently pulled the curtains hanging from the column to the side. Her blue eyes scanned the rest of the bed and found the mound hidden under the sheets where Breatrice’s bottom half would be. She was able to trace the shape of her knees spread wide, leading to the second person laying on their stomach between her legs hidden from view. The Hufflepuff gasped, covering her mouth with her hand. Beatrice lifted her back from the mattress briefly and let out a lustful moan, biting her bottom lip as the shape moved, doing god knows what to her under those sheets.
Chiara slipped behind the column and blinked. She hadn’t expected to stumble across anyone here using the clubhouse to hook up, even if it was becoming more common lately. Her cheeks warmed up as she checked the rest of the floor in her line of sight. It appeared to just be the three of them. She had no idea who the third person was, but when she snuck another peek she glimpsed a pair of legs at the opposite end of the bed. And as she watched Beatrice toss and turn, she saw a pale hand appear from beneath the covers to play with one of her small boobs, their fingers pinching her nipple making her squeal. The hand belonged to a girl, she observed.
She ducked back out of sight, considering her options. She should return to the common room and leave Beatrice to her liaison. But part of Chiara was curious to know who she was having sex with. It couldn’t be Ismerelda, could it? She wondered. The Slytherin witch had become close with the young Hufflepuff. Chiara shook her head. She didn’t buy that. Anyway, she wasn’t one to gossip if they were an item. No, Chiara’s compulsion to stay was something else. Something primal. She could feel it in her core each time she inhaled the scent of arousal drifting from the bed. It was intoxicating, overpowering. Chiara watched the younger girl whimper on the bed and felt a growl rising in her throat, something instinctive and lustful. Her body got warm between her thighs and she bit her bottom lip uncomfortably.
She convinced herself it was another side effect of the full moon, but this wasn’t the first time her transformation left her feeling horny the morning after. A tiny part of her wanted to walk over and climb into that bed and devour the little Hufflepuff girl herself. She could smell her from her hiding place. She smelled sweat. I bet she’d taste even sweater, she thought.
She shook her head and stepped out of sight. Get a hold of yourself. You should go, leave now, get back to studying. Maybe the courtyard will be quiet. You definitely won’t find anyone having sex out there.
She was just about resolved to leave when Beatrice came. Chiara heard her cry out in pleasure and growled softly. One more minute won’t hurt, she thought, turning back to watch the bed, her hand rubbing her groin slowly.
Beatrice collapsed onto the bed panting, her chest rising and falling while she stared at the ceiling. “Holy shit” she gasped, her eyes wide. There was giggling from beneath the sheets and the young girl suddenly shuddered, her knees trembling. She whimpered and tugged on her choppy blonde hair.
The figure beneath the covers climbed up, their hands caressing the girl’s chest before lifting their head up from her lap. “Did you like that?” A friendly voice asked her, a delightful face appearing revealing a mirroring mop of blonde hair braided behind her ears.
Chiara stifled a gasp and clamped her hand over her mouth. The girl rising from Beatrice’s groin was older, the same year as Chiara. A fellow Hufflepuff. “Penny?” She whispered in disbelief.
Beatrice looked up at her older sister, her face turning red. “Yes” she replied meekly. Then she looked away and blushed even redder. “No. I don’t know. Fuck, this feels wrong” she whispered.
Penny looked down at the girl and smiled, crawling over her slowly, kissing up her stomach and licking her erect nipples. Beatrice whimpered, curling up a little until the young woman’s delicate hand lifted her chin to face her. “But it feels so good, doesn’t it?” She whispered, pecking her nose. “Isn’t it fun playing with me, little sister” she cooed, leaning down to kiss Beatrice on the lips.
Beatrice tensed for a moment, pressing her lips together as she looked at the blonde woman. She inhaled shakily before nervously reaching up to stroke Penny’s cheek. She returned the kiss and the two Haywood sisters made out on the bed, naked, passionately.
Chiara watched the two blondes kiss and make love with a confused, shocked and horrified expression. She couldn’t believe her eyes. What? How? Why? WHAT! Yet, as blizzard, taboo and unbelievable as what she was seeing is, she couldn’t take her eyes off it. She couldn’t look away from the two hot girls having lesbian incest on the bed. She pressed her palm against her crotch harder, biting her bottom lip until it might bleed, her stomach growling with need. Why is this turning me on so much?
Her ears picked up footsteps coming this way, from the floor below. Her head snapped around in a panic. Shit! What do I do? Do I warn them? No, I can’t get caught watching this! It’ll be mortifying! She spun around and searched for somewhere to hide. She ducked behind the curtain and held her breath, listening to the footsteps climbing the stairs while Beatrice and Penny continued to make out.
When the visitor got closer, Chiara caught a whiff of her perfume and shampoo. Her eyes narrowed. It smelt familiar. She’d begun memorizing the scents of all of her friends. She cautiously peeked from behind the curtain and her eyes widened in confusion as Penny Haywood walked by her, heading towards the bed.
Wait, but if that’s Penny, then who is kissing Beatrice?
She followed Penny with her gaze as the Hufflepuff walked across the top level in her casual attire, coming to a stop when she heard the sounds of love making ahead of her and freezing when she blundered into view. Her eyes went wide and her mouth fell open. “Beatrice!” She screamed.
Beatrice and “Penny” looked up and saw her standing there. The younger sister went as white as a sheet and froze, her eyes wide like a deer in headlights. Her older sister, the one lying on top of her, stared at her doppelgänger. “Oh, hello” she smiled, climbing off the petrified girl who scrambled out from under her naked body.
Penny stared at the bed, flabbergasted and flustered. “What is going on?” She asked.
Beatrice looked at her, pulling the covers up to cover herself. “It’s not what it looks like” she squeaked.
“I don’t know what it looks like” Penny muttered, staring at her double. “Why…I thought we were supposed to be meeting here, Tonks. Why are you in bed with my sister?” she yelled.
Chiara did a double take as “Penny” gave a sheepish face before that face morphed into another, her blonde hair turning pink and her body changing size into a slim young lanky Hufflepuff. The peeping girl exhaled a sigh of relief when she saw Beatrice head been in bed with Tonks, not her own sister. “Of course” she whispered.
Tonk’s gave Penny an impish grin. “What can I say? I know we were supposed to hook up tonight, but when I got here poor Beatrice was on her own” she explained, putting her arms around the mortified girl. “She’s growing up so fast and I agreed to help her explore her sexuality. We started with a boy she liked…who I won’t share” she promised, catching the younger girl’s embarressed glance. “We were just in the middle of experimenting with some lesbian sex.”
Penny narrowed her eyes, looking at her sister. “That…makes some sense. But that doesn’t explain why you had to take my form to do it?”
“well, she was a little apprehensive about kissing a girl at first, so I figured she’d be more comfortable is I changed into someone she knows. Someone she likes.”
Penny raised an eyebrow. “So you changed into me? To have sex with my little sister?”
“She was very into it” Tonks laughed.
She turned to Beatrice, who had become as red as a tomato. “Is this true?” She asked.
Beatrice blushed, looking between Tonks and Penny, stammering over her words before finally hiding under the covers shamefully.
“Aw. Now you’ve embarressed her” Tonks replied, petting the trembling shape next to her.
Penny shook her head in bewilderment. “I don’t believe this. Why…this is so messed up” she muttered.
Tonks watched the older Haywood pout, climbing off the bed to approach her. “I was just trying to help. I’m sorry if I freaked you out. But be honest…wasn’t there a small part of you that was turned on?” She asked mischievously. “some small, naughty part of you that wondered what it might be like to fool around with your little sister?”
Penny looked up at the pink head girl in disbelief, staring as the young woman suddenly shrank down and took the form of Beatrice. The real Beatrice poked her head out from under the covers and gasped when she saw her own naked self standing in front of Penny with an impish grin.
Penny stared at Tonk’s. “what are you doing?” She gasped, glancing around the clubhouse.
Chiara ducked out of sight, in case she was spotted, listening to the teasing shapeshifter as she spoke in Beatrice’s voice. “You can be honest with me Penny. I already know Beatrice has thought about playing with you. Have you ever thought about playing with me?” She looked back and spied Tonks taking Penny’s hands and placing them on her small breasts, her blonde fringe falling over half her face obscuring the beaming smile.
She also saw the look of shock on Penny’s blushing face. Her eyes darted up to her sister and immediately looked away in shame. On the bed Beatrice was shell shocked.
“I thought so” Tonks cheered, her laugh sounding just like Beatrice’s. She giggled and reached up on her toes to kiss Penny on the cheek. The girl froze, staring at her while Tonks started fiddling with her clothes. “You’ve fantasized about doing it with your sister, haven’t you?” She sang, coaxing her denim jacket over her shoulders.
Penny tensed when she felt Tonk’s hands, Beatrice’s little hands, exploring her chest, groping her boobs and caressing her hips. She shook her head, struggling to get out the words. “This is…this feels wrong” she said.
“But so good” Tonks whispered, capturing Penny’s lips in a kiss. Penny flinched, grabbing Tonks by the shoulders and pushing her away. Tonks giggled and peppered her with kisses, reaching down to lift her yellow dress up and slip her hand beneath it. Penny gasped when she felt her hand between her thighs, her cheeks turning red when she discovered her panties were damp. “Naughty girl” Tonks whispered, dropping down into a crouch.
“What are you doing?” Penny stammered, afraid to look down as the naughty shapeshifter dove under her dress and between her legs. She looked over and was mortified to see Beatrice was watching from the bed, sitting against the pillows, the covers pulled up to her shoulders. She couldn’t see her other hand and feared it was somewhere between her folded knees which drifted apart. Her face flushed when they made eye contact. “Merlin, what are we doing?” Penny gasped.
“Having fun” Tonks answered, looking up at her with a mischievous smile on Beatrice’s face before pulling her panties aside with her fingers. Before Penny could stop her, she had her lips pressed against her clit and felt a tongue lick her. She moaned instictivly, quickly covering her mouth in shame.
Chiara clutched the curtain tighter as she watched Penny get eaten out by her little sister. Even if she knew it wasn’t her, she looked like her and it made her loins burn with arousal. Chiara chided herself, wondering how she could be turned on by this. But she was and she suppressed a growl in her gut. Stupid werewolf hormones, she thought, despite her hand reaching into her unzipped trousers to rub herself. She breathed heavily, biting her bottom lip.
Penny wasn’t as thrilled about this experience as Chiara was, however. She finally looked down at her little sister’s head and shuddered. “Tonks, stop. Please stop!” She begged, grabbing her by her blonde hair and pushing her away from her body. Tonks tried to cling to her thighs, but the Hufflepuff tugged on her hair until she was dragged up to face her. “This is…just no! Alright. Now change back” she snapped.
Tonks pouted, shifting back to her regular face and body. “I thought we were having fun” she whined.
“No. That was…ew” she said, shaking her head. She caught Beatrice’s eye over the shapeshifters shoulder and saw her shy into the covers shamefully. She sighed, fixing her dress. “Please don’t ever do that again” she said.
Tonks held up her hands, crossing her heart. “I promise” she replied apologetically. She looked at the two sisters, innocently pursing her lips. “Can we still have some fun together? I still need to finish Beatrice’s lesson on being a lesbian.”
Penny blinked and let out a humorless laugh. But she saw her sister perk up breifly, even with a blush.
“Come on Penny. It’ll be fun. And it could be a real moment of sisterly bonding” Tonks said encouragingly.
Penny considered it, pursing her lips, looking between her and her sister. Beatrice couldn’t meet her eye, but she kept glancing at her optimistically. She took a slow breath and exhaled heavily. “Fine. If only to keep an eye on you” she told Tonks.
The Hufflepuff cheered for joy as Penny began undressing. Beatrice sat forward, nervously watching her older sister pull her dress over her head and remove her bra. Tonks hopped on the balls of her feet happily. “This is going to be so much fun” she said, giving Penny another kiss.
Penny cringed before pressing her fingers to the excitable girl’s mouth. “First, I want to talk to my sister” she said firmly. “Second, no more shapeshifting. There’s been enough weirdness for one day.”
Tonks groaned. She hated ground rules. She glanced over her shoulder before turning to face Penny. “What if we want to give Beatrice some extras lesson in how to fuck boys?” She asked, and Chiara salivated when she grew an eight inch long penis from her clit.
Penny’s eyes bugged out and she made sure to hide it from Beatrice. “That will freak her out and give her nightmares” she whispered, shutting it down with a glare.
Tonks sighed and retracted her cock, resuming her regular boring but sexy body again.
Once Penny was naked she took her hand and led her to the bed to meet the anxious Beatrice. Penny climbed up and shuffled over to check on her sister. “Are you okay?” She asked her.
She nodded sheepishly. “I’m sorry” she whispered, hugging her knees. “Am I in trouble?”
“That depends” Penny said, glaring at Tonks who was waiting at the edge of the bed. “Were you really into what she was doing with you?”
Beatrice shrugged her shoulders. “I don’t know. I liked it. Kissing a girl, and the other stuff” she confessed.
Penny knelt in front of her, glancing down at her naked self. “Even when she was pretending to be me?” She asked awkwardly.
Beatrice averted her eyes, hesitant to reply. Chiara could sympathize. It was an embarrassing conversation. “A little. But it felt wrong” she admitted.
Penny exhaled, nodding her head. She reached out cautiously and stroked her knee. “For the record…you can talk to me about this stuff. I’m your sister. You have questions, about sex or anything like this, I want to help.”
Beatrice smiled, putting her hand on Penny’s. The covers lowered a little, indicating she was less anxious now.
Tonks shuffled closer. “So does this mean Beatrice is staying for a threesome?” She asked.
Penny looked at her and Beatrice blushed. “Let’s not call it that” Penny suggested.
“I’m not suggesting you two hook up for real. That would be weird” she replied.
Despite the crudeness, it got a chuckle from the Haywood sisters. “Can I stay?” Beatrice asked.
Penny considered it carefully. She could see the girl wanted to take part and Tonks was keen for some more sexy action. She cautiously nodded her head. “Okay, you can stay. But there’s something I want to make sure you understand first” she told her sister. “Whether it’s with a boy or a girl, sex needs to be consensual. That means both parties, or all parties, need to be okay with it. So if at any point you feel uncomfortable, I need you to tell me, okay?”
Beatrice blinked and nodded her head, her eyes darting to Tonks breifly.
Penny must’ve picked up to same subtle cues Chiara noticed because she titled her head, looking at her friend. She leaned closer to ask her “did Tonks make you uncomfortable at any point?”
Beatrice hesitated before looking awkwardly at the metamorphagous. Tonks blinked and inhaled shallowly, a look of guilt crossing her face. “A little bit” she whispered. “When she changed into you.”
Penny resisted the urge to scream or even look at the apologetic Hufflepuff. She kept her attention of her little sister, squeezing her hands. “Well…the next time you’re with someone and they make you feel uncomfortable in any way, you tell them to stop. You can and should tell them to stop” she told her. “And if they don’t take no for an answer…” she added, before abruptly jabbing a fist hard into Tonk’s shoulder, “you’re allowed to make them.”
“Ow!” Tonks gasped, stumbling back and nursing the fresh bruise on her chest. Chiara winced but also cheered the usually cheerful and friendly Hufflepuff on.
Beatrice stifled a giggle as she arched her big sister beat up one of her friends for crossing the line. “Ismeralda always said, if somebody tries to make me do something I don’t want to do I should curse them” she commented.
Penny let out a heavy exhale. “You know I don’t like you doing everything that girl suggests” she pointed out. “But in this instance, I agree with the Slytherin.”
“Alright, you’ve made your point” Tonks pleaded before she got cursed by either sister. “I’m sorry that I made you uncomfortable. I never wanted you to feel pressured or afraid to say no.”
Beatrice nodded, accepting the apology.
“So are we okay?” Tonks asked her protective friend.
“As long as you never change into me or my sister to have sex with anybody ever again” Penny snapped.
“Not even if I asked for permission?” Tonks queried.
The look on Penny’s face told her she would never give permission.
Tonks pouted. “Alright. Cross my heart and hope to die. Now can we please have sex. I’m super horny.”
The two blondes looked at the apologetic Hufflepuff and shared a look. Beatrice grinned and Penny finally broke back into her smile. “Okay. We can have sex now” she said, inviting her over to join them.
Chiara lingered behind the column and watched the three Hufflepuff meet in the center of the bed and begin making out. Once the tension had dissipated there was a playfulness in the air amongst them as Tonks kissed Penny and then Beatrice before being shared between the two sisters. Penny took over the reigns of tutoring Beatrice and used the sexy Nymphodra as a study aid, showing the younger girl how to suck on her nipple while Beatrice practiced with the other one. Tonks expanded her breast size so they had more to work with, moaning softly in enjoyment.
The aspiring healer rubbed herself as she watched, getting aroused at the sight of the three of them. She knew she should go. She should’ve left ages ago. But fuck it, she was horny and they were hot and she couldn’t take her eyes off them. Especially the two sisters now they were together.
Penny and Beatrice never crossed the line Tonks teased them with. Despite what the metamorph had claimed, the awkward glanced and the blushing cheeks demonstrated neither of them were comfortable with the prospect of anything more than holding hands. So they kept their hands to themselves and to Tonks, who they ravished between them like sexy piranhas. When Penny offered her sister the chance to practice oral sex with Tonk’s pussy, the anxious girl chose to sit on her face instead and settled to watch Penny eat her out instead. This let Tonks lick her cunt with her tongue in turn, which made the petite girl moan and whimper. Penny laid down between Tonk’s thighs and played with her pussy. But she didn’t dismiss the opportunity to coax her sister into a lesson of two. Once she was watching her, she taught her how to identify and rub the girl’s clit with her fingers, guiding her small hands over her sex while she fingered Tonks herself.
Within moments the young woman was squirming beneath both their touch, moaning in pleasure squeezing Beatrice’s tiny ass. “Oh yes! Fuck my naughty cunt” she screamed.
“Mind your language!” Penny snapped, threatening to remove her fingers and leave her hanging. Beatrice giggled, enjoying the torment Penny was exuding on the perverted shapeshifter. She suddenly gasped as Tonk’s resumed licking her, her eyes going wide. “Everything okay?” Penny asked.
Beatrice breathed, her expression thoughtful as her hips quivered. “I don’t…oh! Oh my! Her tongue, it’s…fuck! So deep…”
Penny raised an eyebrow and titled her head. “Is it getting longer?” She asked with a curl of a smile. Beatrice giggled and nodded. Chiara saw the smirk of Penny’s face, wondering if that was a popular party trick from the metamorphagous. “Do you want her to stop?” Penny asked. Beatrice shook her head. Her expression was of joy and wonder. Penny grinned, rewarding Tonks with her own tongue inside her pussy.
Chiara’s fingers curled inside of her, pumping like made. Fuck me, she mumbled, biting on the curtain to prevent her moans from escaping. This was so hot and so alluring. She stared at little Beatrice as her small body shuddered from and orgasm before she slumped forward panting rapidly. She watched Penny cradle her grinning face while finishing Tonks off with a climax using her fingers, moving to the side so Beatrice could kiss Tonk’s clit intimately. When Tonks sat up, she had an excited look on her face and captured Penny’s lips, teasing her tongue with her sister’s juices. Penny shoved her back down and Beatrice pounced on her to make out some more.
It was all so erotic and fun and hot, it was driving Chiara wild. She kept fighting the urge to step out from behind the curtain and join them, to rip her clothes off and pounce into bed with the three of them. She have delirious visions of herself ravishing their bodies, teasing their breasts, feasting on their pussy, fingering them silly and fucking them until they passed out. She fantasies about them making love to her, fucking her into a frenzy, playing with her all through the night. She gushed picturing the steamy orgy that could be waiting for her if she would just step out and invite herself.
But her sensible side shoved the animal back into its box. Her affliction was fading, the side effects worn out for now. But she remained, eager to watch them to the finish and get off one last time before she snuck back to her regular normal life. Maybe she was just a pervert who liked watching others have sex. She would suffer the shame later. Right now she was too engrossed in watching Tonks finger the two blonde sisters simultaneously while they lay side by side, their screams mixing together erotically while they clutched each other’s hand.
Savored the looks on their faces as she thrusted her fingers deep into them until they both climaxed together, their pussies squeezing her hands when they gushed like fountains. Beatrice in particular proved to be a screaming as she convulsed against the mattress, her hips buckling into the Hufflepuff’s palm. Penny cradled her exhausted sister when her orgasm faded, kissing the top of her head and letting her snuggled up against her. Tonks crawled over and shared a final kiss with the two of them before slumping down beside her friend. “I’m really sorry about everything” she whispered quietly.
Penny stroked Beatrice’s hair and smiled. “I know you’d never intentionally harm her” she whispered, looking back at the young woman. “I’m open to you helping her, if she has any more questions about sex” she added. “Just run it by me first, okay?”
“Deal” she nodded, resting her head on her elbow. “So are we good?”
Penny grinned. “Of course we are” she said, leaning over and kissing Tonks on the cheek.
The girls cuddled before Penny too stifled a yawn. Tonk’s was too alert for a nap, so she pulled the covers up over the snuggling sisters and left them in bed together. She kissed Beatrice on the cheek and gave Penny one last kiss before bidding them goodnight, putting her clothes back on and leaving the room.
Chiara stayed out of sight, breathing heavily from her final climax which dripped over her fingers. She peeked out at the two Haywood girl’s, who had fallen asleep on the bed cuddling each other. They looked so cute together. She was ashamed she got so aroused at the thought of them having sex. Apparently incest was now a hidden kink of hers, she thought. Not wanting to disturbed them, she took a few silent steps back towards the stairs.
She froze when she backed up into another person lurking behind her. “Enjoy the show?” Tonks whispered when the girl squeaked in fright. The metamorph chuckled and shushed her, peeking out making sure their friends hadn’t woken up. “Aren’t they adorable” she purred, putting her arms around the peeping Hufflepuff.
“I…I was…I didn’t…” Chiara stammered, her cheeks bright red. Tonks reached down and pried her hand out from her trousers, examining the glistening fingers coated in cum. Chiara gulped and blushed profusely.
“You could’ve joined us, you know. We would’ve happily invited you” Tonks whispered, bringing the girls hand to her face so she could lick them clean. Chiara’s belly quivered as she watched her suck on her fingers, instantly feeling herself getting wet again. When she was done, she kissed Chiara on the cheek and zipped up her trousers for her. “But they’re sleeping now, so you have me all to yourself. Let’s go back to our dorm” she said excitedly, dragging Chiara by the wrist out of the clubhouse.
