A Ferocious Drink

Chapter 4: A Night of Luxury

Sweetie Belle trotted home after a day of hanging out with Scootaloo and Apple Bloom, trying to forget about the itch in her neck. The sun was just about setting and they knew that the curse would come for them soon enough, so they each agreed to go to their sisters, or Rainbow Dash in Scootaloo's case, to help them ride it out. She sighed, knowing that it wasn’t going to be easy to convince Rarity of her condition, especially on her private, no-sisters-allowed night.

Creeping through the front door of the boutique, Sweetie Belle saw no sign of Rarity anywhere. The shop was closed for the night for Rarity’s mysterious special event, but it wasn’t in the showroom. She walked up the stairs as she tried to listen for any clue as to where her sister might be, even if she was an uninvited guest.

Sweetie Belle felt a growl build in her throat as she considered the options if Rarity couldn’t help her or shooed her out for being a monster. She couldn’t go back home and the Clubhouse would be empty because her friends were facing the same problem. She could go back to Twilight’s castle, but Starlight suggested that they shouldn’t lead Twilight on while she tried to find a cure for the curse that she had with all her friends and now the Cutie Mark Crusaders.

Another sigh left Sweetie Belle’s muzzle as she reached the top of the stairs to the second floor. Rarity’s bedroom was empty, along with the guest bedroom that she often slept in. However, Rarity’s inspiration room had a light on with the door slightly cracked to the dark hallway. Sweetie Belle bit her lip at the thoughts racing through her mind. She would get scolded for interrupting her sister’s creative process on a regular night, but with an explicit “no-sisters-allowed” night? Sweetie Belle gulped at what Rarity would say to her for disrupting her special night.

Carefully peering through the crack in the door, making sure not to make a sound, Sweetie Belle looked inside the room to see if Rarity was indeed working. A table with several candles illuminated what she could see of the room, along with the light of the full moon shining through the open window. Sweetie Belle’s mouth watered at the glance of the moon, not getting the full effect of the curséd moon.

Rarity’s magical aura came into view as she stepped into the moonlight. She lifted her head as she could feel the heat running through her, holding a hoof to her chest. As the magic inside filled her body, she felt her breasts move up into her furred chest, her body stretching in the moonlight. A growl escaped her muzzle as her fur grew wild and unkempt, her form more accustomed to standing on two legs. Rarity began panting heavily as her tail shifted into a long, bushy tail, feeling pressure between her legs. Her hooves changed into thick, furred paws, perfect for rubbing at herself.

Letting out a long howl to her blesséd moon, Rarity’s canine member grew from between her thick, furred legs, only half-erect from her transformation. Coughing into her paw, Rarity grabbed her mane brush and began to tend to her wild fur.

“I mean, really!” Rarity began, talking to herself in front of her vanity mirror. “Every month with a full moon and t my mane goes absolutely feral! It really is such a hassle.”

Rarity’s voice struggled to stay refined, but there was still a guttural quality to her growls as she attempted to maintain her sanity in her new werewolf form. Sweetie Belle’s cheeks warmed up at the sight of her sister’s monstrous form, her heart racing at the sight of her busty breasts and warm, thick shaft.

“I usually don’t make bipedal clothes, but this should work,” Rarity continued, picking up a sultry dress as she slips it on over her naked body. The fabric of the low-cut dress concealed her chest despite the massive amount of fluffy fur protruding from her ample cleavage. Sweetie Belle watched on, holding a hoof to her mouth to stifle any sudden sounds.

Sitting down at the table, Rarity used her remaining Unicorn horn to drag over a mannequin from the dark, suited in a modest dress from her collection. Rarity’s eyes focused on the figure, attracted to the mare’s physique under her brutish form. She slowly popped off the cork to a bottle of wine within reach, pouring a glass for herself and her distinguished guest.

“Lovely to see you here, darling,” Rarity greeted with a low growl in her throat. She sipped slowly on her glass of wine, licking it off of her lips as she focused on the mannequin. Sweetie Belle looked on in confusion but was still oddly fascinated by her sister’s actions.

“Mmm, not one for conversation,” Rarity commented, running her furry paw on her lap as she could feel her shaft growing stiff at the sight of the dressed figure. “I have to admit, I’m not feeling very lady-like this evening.”

The mannequin stayed quiet as Rarity hiked the edge of her dress up, exposing her hot, red shaft underneath the table. She gulped down the rest of the wine before lolling her tongue out, her eyes glazed over from the overwhelming attraction of her unsuspecting victim. Rarity used her magic to lift her guest’s glass to her, gulping down the wine as well.

“Ahh, not much for drinking either. Why don’t we get down to it?” Rarity asked, standing up from her seat as she grabbed the mare’s foreleg and turned her around. As her sister flipped up the mannequin’s dress, Sweetie Belle saw the strategically placed opening behind the mare’s figure, already slick with synthetic juices. Rarity lifted her dress as she rubbed the tip of her shaft against the mannequin’s rear, thinking that her action was teasing her.

“So wet already?” Rarity growled, holding her seductive tone. “You must want this as much as I do,”

With a loud growl, Rarity thrust her hot, red rod into the opening, gripping onto the mare figure’s shoulder. Feeling the hot, slick lube coating her shaft, she began to pump into it, losing most of her refined appearance.

“Oh fuck, you’re so tight, darling!” Rarity moaned, pushing her canine member deep into the opening, hearing the sounds of warm, scented lube squishing with each thrust. Sweetie Belle’s cheeks turned completely red as her hoof began instinctively rubbing between her hindlegs.

As Rarity continued to pleasure herself with the mannequin, she growled and howled under the shine of the moon from the window. Sweetie Belle sat down softly on her haunches and bit down on her hoof as she could feel her sticky juices leaking onto her other hoof as she rubbed at her wet slit.

Reaching her limit, Rarity felt her shaft throb as she howled loudly and spurted her hot, sticky cum into the opening of the mannequin. Rubbing at her chest, she pulled away from the mare’s figure as the dress fell down the overfill slit, dripping on the floor. A tiny squeak escaped Sweetie Belle’s muzzle as quick spurts of her juices squirted from her pulsing slit. Rarity’s muzzle sniffed the air, realizing that she wasn’t alone.

“Who’s there?” Rarity asked with a snarl, letting her feral instincts start to take over. Tossing the mannequin aside, she prowled around the room on all fours as she followed the scent. Sweetie Belle’s chest beat faster as she felt lightheaded from the impromptu orgasm from watching her sister in secret, unable to work out the proper response to either flee or fight the impending fabulous threat.

Unfortunately, passing out was the option that the young mare ended up choosing in the end.

Rarity whipped her head around to see her sister tumble into the room from the open down, falling into the pool of her sticky juices of relief. The werewolf’s eyes widened as she realized who the uninvited guest was that was watching her from the shadows.

“Sweetie Belle!” Rarity growled as the mare began to wake up from her unconscious state, just enough to see Rarity’s powerful paws pick her up and pin her against the wall. “What are you doing here?!”

“Rar...ity?” Sweetie Belle asked, still a little lightheaded as the vision of the ferocious image of her sister came clear to her. Rarity snarled, her paws gripping onto Sweetie Belle’s coat as she squeezed down on her shoulder. The sharp sensation knocked Sweetie Belle back to her senses, pleading with her life from her kin. “Rarity! It’s me!! Sweetie Belle! Please don’t eat me!”

“What you doing here?!” Rarity asked again, losing her refined speech as her blood began to boil from the intrusion. Sweetie Belle knew it would be bad, she didn’t know it would be this bad.

“I… I’m just like you! Let me go and I’ll show you!” Sweetie Belle asked, gripping her hooves onto Rarity’s huge, furred paws. Rarity’s eyes narrowed at her sister’s frightened expression, holding on to what was left to her sanity as she loosened her grip.

Sweetie Belle fell on the floor, scurrying back on her hooves as she went over to the window to be bathed in the moonlight. Rarity watched on, unsure of what she was looking for as the transformation began to take hold.

“We were infected by Twilight to be just like you!” Sweetie Belle moaned as her body began to stretch out. Her equine breasts shifted up to her chest, remaining petite for her figure. Her hooves shifted into large paws as the fur-covered her body. A long howl escaped her mouth as her muzzle formed, matching with the yellow eyes of the feral wolf. Standing on her hind legs, her tail shifted into a bushy, canine tail much like her sisters. Rubbing down her stomach, the tell-tale hot, red shaft of the curse sprung forth, twitching for attention as her mind began to cross over to her canine instincts.

Rarity’s cheeks reddened under her white fur at the sight of her sister’s new form. She could feel the same energy and magic radiating from her body, turning her on even more. Sweetie Belle’s focus turned to her sister, a sinister grin on her lips as she got down on all fours.

“Wolf like sis! Wolf love sis fucking!” Sweetie Belle growled, circling Rarity as she took in the keen sense of smell from her muzzle. Rarity cackled and howled, rubbing at her dress as the heat began to overtake her yet again.

“Sis good wolf! Make good partner tonight!” Rarity responded in kind as Sweetie Belle tackled her to the ground. In a mash of snarls and teeth, Sweetie Belle’s paws tore at Rarity’s elegant dress, ripping the tatters away from her furred body. Rarity could feel the heat rising in her shaft as her nude body was out in display for her sister to see in its full glory.

Sweetie Belle’s tongue lolled out at the sight of Rarity’s welcoming body, but her mind had other instincts in mind to assert her dominance among the pack. Focusing her magic on her member, her erection lessened just enough to pour a stream of hers on the dress, soaking the floor of the inspiration room. Sweetie Belle let out a sigh as she relieved herself on her sister’s property, calming the feral instincts of the pack. Rarity’s eyes widened as the Unicorn inside her screamed, not turning a blind eye to the indecency that her sister was demonstrating.

“BAD WOLF!” Rarity growled and jumped towards her sister, pinning her to the floor. Letting out her claws, she swiped her paw in front of Sweetie Belle’s muzzle, finding another way to demonstrate her strength to her younger sibling. “No pee in room! Need to punish!”

Holding her paw down on Sweetie Belle’s chest, Rarity leaned down to hear the squeak and whimpers of the werewolf under her. The point had been made, but Rarity’s heart surged through every inch of her new body, her shaft hard as a diamond for some intimate punishment.

Leaning closer, Rarity thrust her hot, red rod into the disobedient werewolf, filling up every inch of her slick, wet opening. She could feel Sweetie Belle’s thick member rubbing against her stomach as she pushed into her, howling at the sensation of the intimacy. Sweetie Belle moaned as her tail flicked underneath her, her chest rising and falling as Rarity’s shaft pumped into her.

Panting with every stroke, Rarity’s tongue lolled out of her mouth as her hips ground against Sweetie Belle. A line of drool dripped out of her muzzle, landing onto her sister’s chest to mat the wild fur that now covered her petite, yet mature breasts. Rarity held her paws on Sweetie’s arms to pin her to the floor, lost in the lust of her feral instincts as she pumped deep into her tight, slick slit.

Sweetie Belle knocked her head back as she felt the pressure building inside her. Her shaft throbbed against Rarity’s wild, yet soft fur, her slick tip matting her sister’s coat. While Rarity continued to push deep inside of her, Sweetie Belle howled as she reached her limit, feeling a wave of pleasure washing over her.

Rarity felt Sweetie Belle’s tip spurt out her hot, sticky juices into her body, landing on her supple, furred breasts. Growling at her sister’s dirty actions, Rarity pulled her slick, red shaft out of her slit and ground against her stomach. Holding Sweetie Belle’s hindlegs up, Rarity ground her member between her thick, furred thighs as she felt herself starting to cum again. She let out a loud howl as she coated Sweetie Belle with her hot, dirty seed, spurting on to her sister’s furred muzzle.

Loosening her grip, Rarity’s werewolf form felt heavy as she fell onto the ground, letting the tip of her shaft leak out on the floor. Sweetie Belle, lost in the pleasure of the rough lovemaking, licked off the mess of her muzzle and rubbed her paws on her chest, wanting more and more of her sister’s taste. Licking her lips, the younger werewolf leaned down onto the floor, lapping at Rarity’s mess and eventually sucking deep on her sister’s member to arouse her again.

“Wolf want more punishment! Wolf like fucking!” Sweetie Belle growled as her muzzle sucked up and down on Rarity’s shaft, growing hard again from the attention. Rarity moaned as she arched her back, wondering how else she could have fun with her little, devious wolf of a sister.

Using her strong hand paws, Rarity pushed Sweetie Belle away from her shaft, making the werewolf fall on her back. Sweetie Belle yelped as her shaft stood erect between her powerful legs, twitching for attention. Rarity licked her lips before leaning down, her long, rough tongue pressing against her sister’s hot, red rod.

Rarity wrapped her muzzle around the tip of Sweetie Belle’s shaft, sucking deeply on the slick, hot member. Sweetie Belle growled and moaned, tensing up as she felt Rarity’s paws grip onto her sister’s thighs as she bobbed her head up and down. Focusing the magic in her horn, Rarity had an idea to satisfy both of them with a little spell of hers. Rarity’s aura enveloped Sweetie Belle’s petite body as her chest pushed out, filling out with muscle rather than increasing the size of her feminine breasts.

Sweetie Belle clenched her paws as her hands expanded in size, letting her shoulders widen as her forearms grew stronger. Her glutes tensed up under Rarity’s soft, furry paws, expanding into a tight rear perfect for punishment. A gurgle escaped her muzzle as Sweetie Belle’s strained feminine voice grew deeper with more feral growls coming from her throat. Her mane shortened into her furry coat, looking more like a male wolf with all of the changes. Once Rarity was satisfied with her magic, she popped her lips off of Sweetie Belle’s shaft and looked up at her handiwork on her sister.

“Oooh! Strong wolf for fucking!” Rarity grinned with a soft growl. Sweetie Belle panted heavily, feeling the testosterone starting to take over as her feminine slit was replaced with a large, heavy sac with a round knot at the edge of her canine rod. Rarity spun around and lifted her tail, using her paw to open her tight, wet slit as her large, limp member hung between her legs. “Fuck now!”

Sweetie Belle howled and mounted her sister, teasing the lady werewolf with her hot shaft. Rarity moaned as her arousal led her down to her shaft, starting to get erect as Sweetie Belle pushed into her slick opening. A long howl escaped her muzzle as Sweetie Belle gripped onto her sister’s body, her furry paws tight on Rarity’s petite forearms. Rarity’s long, red rod stood fully erect as Sweetie Belle began pumping into her from behind.

Rarity’s bushy tail flicked wildly behind her as Sweetie Belle continued to ram her thick member into her. She could feel Sweetie Belle’s round knot rubbing against her spot with every stroke, leading her sister to reach around and grab her ample breasts. Rarity’s hand drifted to her shaft, stroking it in time with her sister’s pumps. Her tongue lolled out of her muzzle with moans and howls, unable to stop the sheer force of Sweetie Belle’s shaft inside of her.

“Knot! Knot!” Rarity cried out, her slick opening aching for more as Sweetie Belle teased her. Sweetie Belle growled into Rarity’s furry ears, forcefully pushing her rod deep inside of her, slipping her round knot into her sister’s slick, tight walls. Rarity howled as she drooled on the floor in front of her. Her shaft began to throb as Sweetie Belle pumped harder into Rarity’s tight slit, feeling every inch of her sister’s hot, thick rod inside of her.

Sweetie Belle howled like one of her paws found her into Rarity’s tight, cushy rear, sending her sister over the edge. Rarity howled as her shaft spurted her hot, sticky mess underneath her, getting all over her paw. Sweetie Belle growled as her member throbbed inside her sister, popping out of her before spurting her own dirty, stick seed all over the fur of Rarity’s back, getting into her mane especially.

Rarity collapses into the pool of her mess, matting her fur more in the process. Her mind is completely blank in the afterglow of being rutted like that during one of her special nights, much less by her little sister. Sweetie Belle sat back down on the floor, gasping for air as her tip leaked out more of her hot, sticky cum onto the floor. She couldn’t believe what she had done, but there was that urge to do it every month, any chance she got.

“Wolf… good… fuck,” Rarity gasped as the room turned dark, falling back on the floor as the curse slowly began to recede from her form, turning her back into a regular Unicorn. Sweetie Belle clenched onto her stomach as her changes started to revert, eventually passing out on the floor of the inspiration room.
