The memories were still fresh and painful in her mind. 
Even worse were the new scars that had developed on her flesh, just scantly hidden by a light layer of fur that was growing back. Each bump of turbulent air sent a light jolt of pain through her body, as she braced herself for landing on the small Phenom 300 jet. 
Wheels screeched to a halt as the plane touched ground, and as if on cue, a light buzzing went off in her pocket. “You have impeccable timing,” Emily mused, bringing the cell phone up to her cheek.
“It comes with our territory, doesn’t it?” Ty asked, letting out a quiet chuckle into the speaker. “Besides, you’re right on time, as always. It’s good to know you’re home safe…”
The pressure of the plane coming to a complete stop sunk Emily into her seat, and she let out a sigh of relief as the aircraft finally came down to a taxi speed. “Mostly safe, anyway. I assume you’re already here?”
We’ll be arriving at gate B5 in one minute. Please remain seated with your seatbelt fastened until the plane has come to a complete stop.
Tiberius was standing in front of an arrivals display screen at the airport, resting back on his hind set of legs with a bored disposition. “I’ve been here for a couple minutes.”
“Don’t worry,” Emily said quietly, unbuckling her seat belt the moment that the Phenom 300 was docked into the gate. “I’ll be right there.”

“You’re hurt…”
Ty greeted Emily with a worrisome look and a cautiously tight squeeze around the shoulders, not wanting to aggravate any pains that might be waiting under the surface. “Eep!” she yelped, as he brother grabbed her up in a sudden, affectionate display. “It’s just a couple of flesh wounds, Ty…I’m fine.”
“Promise?” her brother pried.
Emily laughed quietly and gave a reassuring nod. “I promise,” she said confidently. “Mind letting me go so we can get back to the car?”
“Only if I have to,” Ty replied, slowly releasing his sister, almost regretfully. “I was able to grab a spot right outside of the arrivals line. Do you have everything you need?”
All that Emily had brought along with her was a small, four-wheeled carry-on bag, sitting behind her. In their affectionate greeting, she’d almost forgotten it was there. “Just this, Ty. Would you mind being a gentleman and rolling it to the car for me? I am a tidbit tired.”
The grey-furred taur quickly took up the handle of the carry-on and started rolling it along. “I’d be glad to, Em. You’re just lucky you’re a little banged up.” A quick wink made it clear that Ty was simply playing around, and Emily returned the playful gesture.
“Thank you, Ty,” she said, reaching up a handpaw to brush her long, flowing blonde locks away from her eyes. “You do seem awfully eager to get home, though. Is everything alright?”
Ty nodded. “I’m fine, but you need your rest, Em, and I’m just really glad to have you home safely again. The sooner we can be back at the house and relaxing, the better.”
Emily wanted to protest that she was perfectly okay, but every step they took back to the car, short as the walk was, reminded her of a couple nagging cuts that were still wrapped in tight, white bandages. Her mind was still trying to settle down as well, but her training as an assassin was so deeply ingrained into her very being that even now, she was putting on a tough front, not even wanting to let her brother see her wince. 
“I suppose you have a point. We’ll have the place to ourselves, right?”
“Of course. Perfect for a good, quiet evening.”
Ty stopped at the car and opened the trunk, setting the luggage into the back with relative ease. “That sounds like a plan to me, Ty. Thanks again for carrying that,” Emily said, stepping around the car on all four of her legs to give her brother a tight embrace. Though it was only around him, sometimes, Emily could allow herself to be mortal again, and drop the front of being an emotionless, invulnerable killing machine. 
“It’s no problem, Em. Mind letting go of me so we can get in the car?” he asked, poking fun at her for saying the same earlier. 
Emily broke the embrace, giving Ty a gentle shove and sticking the very tip of her pink tongue out at him. “Only since you were so polite,” she affirmed, turning and batting the fluffy end of her foxtaur tail at his chest. 
With a sigh of relief, Ty closed the trunk and helped himself into the car as well, cursing himself for even giving a hint to the urgency he felt for returning home. 
**
Emily had been trained extremely well as an assassin, and part of that training was picking out something that didn’t seem normal, or something that was clearly off. Her senses had been heightened, and her scent was no exception. Though she was too distracted by her recent mission to say anything, she felt as though she was nearly drowning in the scent of arousal coming off of her brother. 
It’s so cute how he thinks he can hide it from me, she thought.
Ty was still convinced that he was being sneaky about his intentions, even as the siblings returned home, parked the car, and unloaded Emily’s things into the living room. As sore as she’d started to feel, and as busy as Ty had been that day, it wasn’t long before the two taurs were simply resting on the living room floor, their hind legs curled underneath them. 
Emily was clearly the more tired of the two, as her eyes started to lid over. “I may just curl up and sleep here for the night, Ty. I’m a little sorer than I imagined.”
Ty did his best to keep his ears from flattening in disappointment. He was already struggling to stay focused on words, as his eyes took an appreciative look over his sister. She was quite a lovely foxtaur, with long, blonde hair flowing all the way down to the crest of her back, and soft, vibrant orange fur that any vixen would be jealous of, with the perfect complement of cream on her underbelly. The bandages were an even brighter white, by stark contrast.
“Perhaps I could try and help ease your pain a little bit?” the grey foxtaur asked, and despite his more sensual intentions, Emily could hear that this was a sincere offer. Though she’d caught the scent of arousal on him many times, Ty was truly a loving and caring sibling, first and foremost. 
Emily let out a bit of a heavy sigh. She was truly sore, and at the moment, curling up and sleeping off a stressful mission was all that she could think about. Still, trusting in her brother, she leaned her legs down forward, sprawling out over the living room floor, and only then, she started to unbutton her top, denying her sibling from any sort of a favorable view. “Very well, Ty. If you really think you can help, my back and shoulders are a little bit pained, still.”
Ty watched with certain eagerness as the long sleeved shirt started to fall off of his sister’s shoulders, bringing the bright orange fur upon them to his sight. Even from the back, he could tell that the light taping on her wounds didn’t cover her breasts, much to his delight. Still, he wanted to seem as innocent as he possibly could in all of this, fully unaware that his sister was already picking up on his intentions. 
“I’ve never failed to make you feel better before, right?” Ty asked facetiously, resting his paws upon Emily’s shoulders. The male foxtaur let out a quiet breath to ease himself, before going to the task of easing his sister. With an expert touch, Ty pressed his pawpads as delicately into his sister’s sore, tired shoulders as he could, drawing a pained gasp from the vixentaur. 
“Ahhn! G…gentle, please…” Emily pleaded, and immediately, her request was met. Ty flattened his ears in the very same moment, feeling guilty for causing his sister any pain, but as he eased up his touch just a bit further, Emily lowered her shoulders, releasing the tension in them little by little. “Ooh. Much better, Ty. Keep going like that…”
Though he certainly didn’t need any encouragement, Ty picked up his tail and flickered it about as he gained his sister’s approval. From his crouched position behind her, Ty could feel Emily’s tail starting to wag just a little bit as well, giving him a further clue that he was doing a good job. As the pain started to melt out of her shoulders, Emily could feel Ty working his paws down along her spine, using the faintest tips of his claws to tickle and tease under her fur. She was almost ashamed of how much she had let her guard down, but it was getting to a point that she couldn’t help it. Her resistance was fading as well, much as the thought of mating with her brother had been the last thing on her mind only minutes ago, it was starting to creep to the front of her thoughts. A quiet, delighted purring was escaping her muzzle each time that Ty used his masterfully soft paws to work the stress away from her muscles.
“Mind if I go a little lower?”
Emily was surprised that Ty would be so bold, so much that she actually turned back over her shoulder to look at him. She could almost see and feel the warmth in his cheeks, knowing that he had to feel at least a little shy inside to say such a thing, but the look in his eyes made it clear he wasn’t joking. 
Still… she mulled over in her mind, I should reward him for being so forward about it.
“Only if you don’t intend on stopping there. There’s only one thing better than a back massage for releasing stress, after all,” Emily pointed out, as she brought her elbows in and folded her arms back, letting her soft white button-up shirt slip completely off of her back. True to her stealth nature, she’d undone the remaining buttons with Ty none the wiser, and now, her shirt rested carelessly on the floor.
Ty was flabbergasted. His paws seized up, stopped right at the crest of where her back met to the taur half of her body, now fully exposed to him, naked as the day she was born. “You…you knew the whole time, didn’t you?”
Emily gave her brother a lopsided grin. “Of course I did, dear brother. Have you already forgotten all the training we had at the Agency?”
Ty knew that his scent must have been strong on the air, but he wasn’t aware that it was so potent. He’d only been focused on the delicious scent of his sister, and his senses had been clouded almost entirely as a result. He suddenly felt rather fortunate that this wasn’t a contract hit, as sloppy as he’d been. “Not at all, but this is different!”
“It’s quite the same, Ty. You have an objective, you put in the training to prepare yourself for it, and you’ve progressed this far in the mission. Now, are you going to go in for the kill, or not?”
“Em…”
Ty looked into his sister’s amethyst eyes with a smoldering glare from his own deep emeralds. Part of them both knew that the typical nuclear family would look down upon their actions, and maybe even publicly condemn them, but…they knew all too well that they were no ordinary nuclear family. Their fates had been altered, their parents killed, and their entire lives had been changed.
They knew better than anyone else that sometimes, having only one other person in your life could bring you closer to them than you’d ever imagined. They knew it could be wrong as their muzzles met in a shy, unsure, questioning kiss. Even the delightful shock of tasting the lips of a lover didn’t hit them right away, as their thoughts were clouded with the now pointless battle of right and wrong. 
The moment that Ty took Emily’s paw in his own and gently squeezed it, overwhelmed with the sensation of a deep, passionate and meaningful kiss, none of that mattered anymore. 
“Mnn!” Emily gasped; still shocked by the kiss, even as she knew it was coming. Societal norms would have told her to back away, but instinct told her to stay right where she was, and she gladly listened to the voice inside instead. She pressed on even further, letting her muzzle open just enough for her tongue to break the last boundary of the kiss, licking at her brother’s lips. Her tail made a delighted curl as Ty obliged, opening his lips to his sister so she could taste and explore all that she wished, sharing a thin drip of saliva between them. Only moments ago, she was hesitant, and now, Emily was pushing her brother for the act almost as much as he’d been pressing her. Still having a free paw, the eager vixentaur reached that paw into her brother’s trademark vest, undoing each button with expert ease, leaving both taurs stark naked in their embrace upon the floor. 
Ty felt his own gasp muffled by the depth of the kiss, and he wasn’t going to complain about it. As they went on, it turned from less of a gasp to a quiet, low moan, and suddenly, he was glad that Emily couldn’t hear him, even if she wanted to. Even if he could speak, Ty would just be begging his sister to let him finally mount and take her like a proper taur she be taken. His lips tried to convey the message as they moved in a gentle pattern over his vixentaur sister’s, sharing the kind of kiss no two siblings should ever have shared, or so they were taught. Now that they were in the moment, there was no stopping them, and their scent of their combined arousal was making them lightheaded. 
It’s obviously been way too long since you’ve had any attention, Em, Ty thought, as he could feel his member starting to come to life between his legs. From the position he’d started the kiss, he was just a small adjustment from lining up to and finally penetrating Emily. So close…I need it so bad!
“Do it,” Emily said in a quiet, muffled voice, having separated their lips just enough for her to speak. “Pin me down and mount me, Ty…I’m ready for you, please!”
The sudden order from Emily sounded more like a desperate moan than anything else, and it traveled across Ty’s ears like a siren’s melody. Even if he wanted to, he could never have resisted it, and his body was just as ready as her own, with his cock now standing at full attention between his hind set of legs. With a half jump, Ty moved his hind legs between Emily’s and rested above her, letting his front legs wrap around her stomach and hold her nice and tight, making it clear that he wasn’t going to be letting go for anything until they were done. Like a true vixen, Emily’s labia radiated delightful warmth that Ty could just feel on the tip of his length, and it was impossible to resist. 
“Emily, it’s…it’s so hot…” Ty said, starting to lose his voice to pleasure as the glans of his length nestled right into his sister’s outer lips. The moisture of her arousal cloaked the head of her brother’s length and started to travel down along the shaft, as if she were leaking desire for him. It was more than enough lubrication for Ty to ease the rest of his cock into her tight, perfectly wet pussy. 
“Oooh…that’s it, nice and slow, Ty…yes…yes!!” Emily praised with growing fervor, until she erupted in a full on moan. Her two sets of legs started to lift up off the ground a little bit to encourage her brother to dig deeper, putting their bodies at just the perfect angle for some deep penetration. “Ty…you feel so amazing…I wish I’d let you talk me into this sooner!”
Ty felt a tail curl around his back, the soft, fluffy fur of his sister slipping up and down over his back to encourage him to be a little rougher with her. Any memories of being sore were far and away from Emily now, replaced entirely by dreams of pleasure and desperate arousal. “I had never dreamed fucking you could feel this…this great, Em…ooh!” the male foxtaur cried out mid-sentence, feeling a sudden clenching upon his length that was even tighter than his already gripping sister felt before. “How did you…?”
“An assassin has to have perfect control of all of her muscles, Ty…even those ones,” Emily quickly and cheekily pointed out. Though her brother was riding her and picking up the pace, she was suddenly the one in control as every few thrusts, her vaginal walls would clench and contract on Ty’s cock, trying to keep him off balance so she could toy with him a little bit. Her intention was to get railed as hard as she could, now, but she had to tease her brother first, at least a little bit. 
“I’ve never felt anything…anything like t-that!” Ty tried to simply explain, but his voice was lost to a pleasured moan as his front paws started gripping tightly upon Emily’s stomach. His claws tried not to dig in too deeply, but he just couldn’t help it, and suddenly, Emily knew pain again, but this was a different kind of pain to her. She welcomed it, digging the claws of her hind legs into the carpet for more traction, and suddenly, Ty was getting a little bit deeper in on each thrust, as his member was glistening already with the flowing juices of Emily’s arousal. A small puddle had already started to form in the carpet from all of the drippings of their lovemaking. “Oooh! Emily…I need this…I need you!”
The sneaky vixentaur could only ignore the exhaustion of her body for so long, but she desperately desired something that her brother yet withheld from her. As her mind started to simply drown in pleasure, Emily clenched her entrance as tight as she could around her brother’s mast, and the moment he would thrust full to hilt her, she’d release at the base and squeeze at his tip, holding his throbbing flesh as deeply within her as she could. “Then why don’t…mnnn! Why don’t you give me what I need, brother?” Emily asked, as if her brother actually had a good reason not to. 
“Em…I…are you sure?” Ty gasped breathlessly, though his body clearly had no such question or concern, as his sizable taur body kept Emily pinned down tightly to the carpet, now thoroughly moistened by the desire of their taboo mateship. 
“I want you to, so badly…do it, Ty!” Emily commanded, and suddenly, she felt a thrill greater than any she’d ever felt on even the most daring mission. Chills filled the entirety of her being as every sore, tired muscle she had clenched and tightened. She could feel the tight, bulbous knot on her brother’s length starting to break through her slick labia, and her orgasm quickly followed, heralded by a quick gush of her arousal down the whole of her brother’s cock. The sudden rush, the realization that she’d truly just been mounted and taken by her brother, and the first spurts of incestuous seed that she felt inside of her were simply too much to take. “Ty!! Yes, I can feel it…you’re making me cum, Ty…give me all of that sweet, hot cum!”
Ty was already gritting his fangs tightly together to try and last even moments more, but already, he could feel a familiar tingling in his tummy, and the tight clenching of every muscle in his core signaled that he was far too late to hold back. Thick, sticky spurts of his seed exploded off the tip of his canine member, held firmly inside of his sister by a perfect fitting knot, and the masterful clenching of her inner walls. “I’m cumming, Em…I can’t help it…ahhn!” he moaned, but the easy moans quickly turned into a chorus of pleasured howls, and that voice, strained with pleasure, joined with that of his vixentaur sister, filling their household and turning it into their own chapel of bliss. 
**
With a quiet, solid pop, Ty pulled free from his sister and spilled the excessive flow of his semen out onto the already pleasure stained carpet. Only fifteen minutes had passed since the peak of their joined climax, making it a rather short tie, but in the passionate embrace that followed the rough romp, exhaustion came back to Emily, and she couldn’t shed herself of it. She rested in her brother’s arms, even after their sexes were separated. 
Her eyes only stirred again as she felt a gentle, affectionate kiss upon the back of her ear. “Feeling a little better, Em?” It was indeed Ty, and what Emily had wondered about being a dream was certainly reality. 
“Still quite sore and ready for something more than a nap, but I couldn’t be happier, Ty. Just one thing…”
“Yes?”
Emily rolled over onto her side and took Ty with her, grinning as her soft, lengthy tail brushed over his back with a comforting stroke. “The next time that you feel such a need to mate with me when I’m sore, I’m gonna be on top.”
Ty just smiled to himself and rested against his sister on the floor, knowing that he’d feel that need again before too long. “Duly noted, dear sister.”
