Asa and his younger sister Fawn were both sitting cross legged in front of the small TV at the front of the living room of his college apartment. Both were grasping video game controllers in their hands and frantically pressing the buttons as they battled each other in some fantastical, impossibly magical setting with overpowered avatars and large weapons. Empty beer bottles and a mostly empty pizza box were scattered across a small table behind them. There was an old couch against the far wall but this gaming session was far too serious for such relaxation.

Asa was old enough to drink but Fawn could only sneak forbidden sips of his beer since she was nearly two years younger. This was her first year of college and she spent nearly all her free time here with her older brother instead of seeking out friends and companions among her classmates. Asa couldn't object since he was equally as introverted in that way. They were good enough friends with each other and held similar tastes in entertainment: video games mostly, and other nerdy pursuits. It wasn't that they were deficient in good qualities though. Asa was a tall, skinny thing while Fawn was more of a pipsqueak, but both of them were fiercely humorous and quick to speak their minds in tense situations.

"Don't you fucking dare!" Fawn croaked as she angled her body along with the movements of her avatar on the screen, quite unconsciously. "Not today, buster!"

Asa only smirked as he expertly timed his attacks and defensive movements in response to hers, easily displaying his mastery of this game and countering her every move. She groaned as he avoided her ultimate attack and inflicted his own for the winning blow.

"You jerk!" Fawn cried as she dropped the controller and punched him in the arm. "I was so close to beating you."

Asa laughed as he stretched his arms over his head. "It'll never happen."

Outside the apartment, a rainstorm was brewing and thunder could be barely heard. On rainy nights like this, their favorite thing was to settle in front of the TV and watch a movie with the lights out. Now that Fawn had lost the pretend battle quite utterly, this seemed as good a time as any.

"Hang on, I gotta pee," she said as she hopped up from the floor. "Find a good sci-fi or something."

Asa dropped his controller and replaced it with the TV remote. He plopped himself on the couch and flipped through the channels until he found some old alien flick that they had seen a hundred times before. By the time Fawn had returned, she was wearing a pajama onesie that was supposed to resemble a shark. It was her favorite "relax" outfit even though it was starting to get worn out after years of use. Since she hadn't grown much since first getting it, however, she could easily fit into it still.

The beer was starting to get to them both, Fawn first, and she was nodding off on the couch next to Asa just as his eyes started to feel heavy. It was Friday night and they could sleep in the next day, although technically Asa had some homework that was due Monday that he had yet to start. He had a tendency to let the weekends get away from him.

"Asa?" Fawn's tired voice piped up. "I feel...funny."

Asa glanced over at her and at first he didn't notice anything strange, however after a few seconds there did seem to be something different about her. A glow of sorts, or some kind of shiny quality to her skin that he knew wasn't normal. He felt an electricity in the air that was growing steadily, causing a tingling feeling in his own skin. He glanced down at his hands and saw the same shininess.

"What the...?"

Fawn was still mostly out of it, as the electricity that was building in the air was also draining her of all remaining energy. The TV had started to flicker and was now showing static. Asa flexed his fingers to fight the strange sensation of his blood curdling beneath his skin. It wasn't painful, but something was terribly wrong at this moment. When he glanced back at his sister, he saw that her shiny skin was becoming somewhat translucent now, like she was fading away entirely.

"Am I dreaming?" he asked aloud.

The TV had started making a loud noise but it quickly faded into nothing as he lost all sensation of his surroundings. He couldn't feel the couch beneath him and he couldn't seem to breathe, though it didn't make him panic like he would have imagined. Instead he felt as if his very life was slipping away, melting into nothing.

"Asa?" Fawn's voice was so distant he could barely hear it.

Asa's vision went dark now, though strangely the sound of thunder outside was clear and loud suddenly, and a bright flash of light filled his vision and overwhelmed him with sensation. Had they just been struck by lightning? For a flash of time he felt like his mind was on fire, but then it passed quickly and he was clouded in darkness and silence.

For a long moment that stretched into minutes, Asa was paralyzed by the nothingness. He was aware, barely, but it wasn't complete lucidity. It was like a dream that he knew he was having but he couldn't control or influence in any way. The darkness slowly lifted and he felt his heavy eyelids fighting to open, held back by a fatigue that made him feel like he was using his body for the very first time. He tried to move but his muscles weren't responding. He worried for Fawn, wondering if she was still next to him on the couch, except when his eyes finally opened he was sure that he was still dreaming.

Instead of his meager apartment, Asa felt the cool breeze of a sunny morning waft across his face. The brisk feeling helped him stir awake, though the fatigue was still wearing down on him. He inhaled deeply, again feeling like his lungs were only now being used for the first time ever, and the smell of the crisp air was refreshing. He was definitely outdoors now, but how had that happened? Had someone rescued him from inside his apartment? Maybe there had been a gas leak and someone had carried him out.

With a sudden anxiety, Asa turned his head to the side, where Fawn had been falling asleep beside him on the couch. She was next to him still, but they were definitely outside on the bare ground. This wasn't the apartment, and it wasn't even anywhere close to it. All around him were trees and grass and a well-worn dirt path that he was seemingly laying on with his sister. He sat up now, newly alert and wondering what the hell had just happened. He remembered the static on the TV, the strange shiny sensation on his skin, the thunder outside...

Fawn was stirring now inside of her onesie, or at least he initially thought she was still wearing her pajamas. The soft fabric of the onesie was different somehow upon closer examination, fluffier and even softer than it should have been. He was transfixed by the sight of it actually, watching her gentle breathing and the rise and fall of her body. When she groaned and rolled over, he almost jumped back at how she appeared now: her skin was not the usual smooth pale color but now she seemed covered in luxurious cream fur of some kind, not just part of a piece of clothing but attached to her actual body. Her complete lack of clothing allowed him to see that she was covered in this fur, head to toe, and her face even had remnants of it, just like a cat girl from some cheesy anime. A set of large pointed ears at the top corners of her head matched this description aptly.

"What the fuck?!" he exclaimed.

Fawn's eyes blinked open now and she stretched, as if she had just finished a satisfying slumber, and she frowned at him. "What's happening? Is something wrong?"

It was either Asa's shocked expression or the fact that he too was now some anthropomorphic version of himself, covered in similar fur but a darker shade of grey, that made Fawn's eyes open wide while she mirrored his shocked expression. The two siblings stared at each other for the longest time, noting the characteristics of the other person with more and more surprise.

Asa's body was more of a masculine animalistic version of his sister, his fur more patchy and of a shorter length, and his hands and feet were mostly human-like but with sharp white claws at the ends of his fingers. He was grey all over his body except for his face which was a soft white color, and his ears were long and rounded on the ends, extending nearly straight out from the sides of his head. He was the same basic overall shape as before, tall and thin, but there was a somewhat notable difference that he could not even attempt to hide: his penis was now a thick appendage that dangled freely between his legs, protruding from a modest clump of white fur at his groin. His testicles were smooth and hairless though, oddly enough, but they too seemed larger than before, fuller perhaps.

Fawn's eyes occasionally darted down to see his genitals, but of course the rest of him was so shocking that she could hardly focus on only one part. Her creamy fur covered her entire body but she somehow had a very feminine shape to her still, not just a tiny pipsqueak anymore but an elegant form that included slender legs and wide hips. Her generous breasts were prominently on display and were covered in short fur everywhere except her pink puffy nipples. Her creamy fur grew just the slightest bit thicker as it neared her crotch but was not quite so thick as Asa's pubic region. Her vagina was easily seen below this region, both her lips and the hood of her prominent clit. Asa swallowed as he took in the sight of it, trying his best not to linger. It was difficult because the sight of her was doing something to him that he had never experienced before.

His thick penis stirred awake now and began to swell and stiffen, much to his chagrin. He felt embarrassed but there was no hiding what was happening to him. With both of them standing there in the middle of a well-worn dirt path, he grew fully erect in front of his sister, unable to do anything about it. Fawn saw this happen and could not resist staring at his penis on display.

"Wow..." She nervously swallowed too.

It was more than an embarrassing moment though; Asa felt a strange sensation in his stomach and his balls were tingling with arousal, the likes of which he hadn't ever felt before. He had the sudden compulsion to fuck something, anything, and his cock jumped and throbbed in the gentle breeze.

"...Sorry Fawn..." He felt he had to apologize for this, despite his complete inability to stop the reaction.

Fawn tore her eyes away from his penis, though she was truly impressed at its size. She had never so much as wondered about something so private pertaining to her brother. They had never even seen each other naked before, that she could remember. Nothing about their relationship had ever been so lewd or forbidden.

"What is happening?" she asked finally, more about the entire situation than just his uncontrollable erection.

Asa shook his head. "Are we dreaming?"

They both glanced around, looking for anything that would clue them in to their current predicament. There was no one else around, no sign of life anywhere close by, and they might be in the middle of some forest somewhere. If this was a dream, then it was the strangest one either of them had ever had.

Cum... The word was whispered from somewhere, causing Asa's head to twist from side to side to see who was speaking. There was no one around, but a voice was definitely heard.

"What was that?" Fawn asked, apparently having heard it too.

Cum...

It was surreal to hear such an obscene word being whispered to them both from seemingly nowhere. What did it even mean? How could it possibly be real?

Cum...

Asa's cock lurched again, causing him to audibly groan with sexual tension. He had never felt so horny in all his life that he could remember. He reached down to squeeze his cock, mostly to hide it, but the sensation of his hand pressing against his engorged member felt really, really good.

Cum...

The strange whispering continued, and each time he heard it his balls seemed to draw further up into his sack. He shot a worried glance to Fawn, but she too had a glassy look to her eyes now, and her mouth was hanging open slightly.

Drink...

Almost in response to the strange voice, Asa saw his sister drop to her knees in front of him as if she were in a trance.

"Fawn?!" He couldn't believe what he was seeing.

Fawn looked up at him with a pleading, dreamy look. "I...can't seem to...help myself."

Asa felt the uncontrollable sexual urge within himself grow exponentially, causing him to squeeze his cock even harder until he was nearly jerking himself off right in front of his own sister. Her furry body was becoming more and more sensual to him at this moment, and he noted her nipples standing up at the tips of her pert breasts. Fawn's mouth opened more, almost as if she were beckoning him to do something he had never once pictured doing with her.

Cum...

Drink...

Each of them heard the commands, though the first seemed more urgent for Asa and the latter was causing a spell to come over Fawn.

"Asa...I think you have to..." Her tongue extended out of her mouth now and she was openly begging for him to perform this lewd act that neither of them would ever be able to forgive themselves for.

"I can't...can I?" His question was more of an internal observation than a plea to his sister.

Cum...

Drink...

Finally he couldn't take it anymore, and Asa openly masturbated his big cock right where he stood. He was jerking himself with his hand, careful not to let his new claws do any damage, and he could only watch in horrified fascination as Fawn kept her mouth open and stared up at him directly, making eye contact with him. His stare kept darting between those pleading eyes and the sensual mouth that was open and beckoning for his cum.

"How can I do this..." He was fighting with himself even though his actions were already set in motion.

Cum...

Drink...

Asa abandoned all hope of saving his reputation and his dignity now. He only worried still for Fawn at this point, imagining that she would be completely grossed out and run away screaming at any moment. Instead, to his amazement, she openly reached between her legs and masturbated herself too. That was the tipping point and he moaned loudly as the cum boiled up from within him, rising up his shaft while his balls tightened as he prepared to spew his load. It felt different than his usual masturbatory sessions, somehow stronger and passing throughout his entire body rather than just his groin. The tingling that he normally felt in his balls was spreading to his thighs and stomach, even reaching up to his chest as he felt his heartbeat quicken.

"I'm...cumming!" he announced, giving one last glance down at his sister and expecting to see...something other than what awaited him.

Fawn's face was completely entranced and her eyes closed finally as she prepared to take her brother's hot load in her mouth.

Cum...

Drink...

That damned whispering! Asa didn't hold back though and tried his best to aim his cock at his sister's mouth, however at best he managed to aim for her face in general as he felt his shaft thicken even more and expand to let his hot sperm burst forth from his cock. He grunted forcefully as the first ejaculation burst out and sprayed across Fawn's face, covering her furry features with a thick white rope of warm obscenity. She didn't move a muscle though, and barely flinched as the second burst followed suit and went even further over the top of her head. Asa was weakly thrusting his hips forward as his hand expertly squeezed and manipulated the underside of his cock head, doing what came natural for a young man to do when he masturbated. He continued firing thick ropes of cum onto his sister's face until he was dribbling the last bits of fluid directly onto her tongue. He let out a heavy sigh now as his orgasm faded, but the tingling pleasure seemed to continue coursing through his veins and he felt a pleasant burning sensation all over himself now.

It was easily the best orgasm of his life, and it somehow proved to him that this wasn't a mere dream but was very real. That might prove problematic...

Fawn opened her eyes finally and stared up at her big brother as he weakly squeezed the last of his cum into her open mouth. She eagerly accepted it, surprising herself at how lewd and obscene she was being in this moment. She felt his warm semen rolling around her tongue and she instinctively swallowed it, then boldly leaned forward and licked at his penis where it was still dripping sperm. Asa had let go of his cock finally, only for her mouth to replace his hand. She sucked on his cock unabashedly now, still masturbating herself but reaching her other hand up to grasp onto his shaft and hold it in place while she sucked out every drop of cum she could gather.

Asa watched in horrified pleasure as his own sister orally serviced him. What he had done was bad enough, but now she was eagerly participating in this forbidden act in return. Seeing her strange furry features helped only the slightest bit because he knew it was still her, no doubt and no question, and this was still wrong.

"Ah, that's better!" A squeaky voice interrupted the moment, causing both of their heads to turn toward the sound.

Floating in the air only a few feet away from them was a tiny person with wings, with white hair and a childish appearance. The tiny person was like a fairy, barely three feet tall with smallish arms and legs, wearing a beautifully crafted dress with blue and pink colored patterns. It was like a small girl with butterfly wings attached to her back. She wore a diadem of intricate design, with sparkling diamond stones glittering in the sunlight. She was beaming brightly at them despite the rather awkward situation.

Asa jumped back now, finally able to think with a somewhat clear head now that the overwhelming sexual tension was gone from his awareness. His cock was still standing quite erect now, huge and dripping with saliva and semen, but he didn't bother to hide it. His face reflected complete terror as he realized someone had seen what had just happened. Fawn was equally surprised but she stayed on her knees and savored the taste of her brother's cum, which tasted better than anything she had ever sampled before in her entire life, the reasons for which she could not identify.

"Who are you?!" Asa exclaimed, pointing at the fairy.

She remained floating in the air but bowed her head respectfully. "Thank you for summoning me! I was worried that you would try to fight the urge. Usually you Otherworlders succumb much more easily."

"Urge?" He shook his head in confusion. "You did that to me?"

The fairy nodded. "Of course! How else would you expect to survive here? Also, I wouldn't be here if it wasn't for you doing that. Are you complaining?"

The question seemed like a joke to the fairy, but it was definitely not to Asa. "What the fuck? Why would you do that to me? You wanted me to cum on my sister?"

The fairy's bright smile faded slightly, but not completely. "Your sister? Really?! Oh my, that wasn't part of the plan. I need to bring this up with the Elders later."

"Elders?" Fawn stood finally, licking her fingers where she had been holding Asa's cock moments ago. She couldn't get enough of his sperm, it seemed. Thankfully it still decorated her face and she could scoop those last bits into her mouth.

"Where the hell are we?" Asa demanded now, ignoring his thick cock still sprouting between his legs. When Fawn stood next to him, it almost appeared as if she was tempted to reach out and grab it, even after what had already happened.

The fairy flew closer to them now, bobbing slightly in the air. "You've been summoned to this world, called Escoria, as part of a special favor to the Gods of Light. You should be honored! You were selected from a vast array of-"
