Jade is property of SnJester

With a slight groan the grey furred vixen stretched hir arms above hir head and kicked the door closed as shi walked inside. "I'm home!" shi called out as she padded into the living room.

"Welcome home Jade, how was the movie?" came a feminine voice from the sofa with a large pair of paws hanging off of the armrest.

"Disappointing, I expected some more action from the previews." Shi came around to the front of the couch to see hir younger sister sprawled out on it. "Krys, where are Mom, Dad and the cubs?"

"They went to see Aunt Gin. They'll be back in a few days," replied the younger silver vixen.

Jade looked hir sister over as shi lay stretched out. Hir younger sibling was over seven feet tall and covered in muscle, but still had that stereotypical sexy vixen shape... and she was only 15 years old. The smaller vixen chuckled. "You know sis, if you keep growing like they say you will, you won't be able to fit on that sofa anymore."

The younger sibling grinned widely, showing off hir sharp fangs. "Aww you don't want your lil' sister to grow up all big and strong?" Shi flexed hir arm, showing off the powerful muscles. Krys grinned with delight as shi watched that powerful arm flex, very proud of hir strength. She stood up for a stretch and smiled as shi looked down at Jade from hir seven foot and six inch height. "So that means we have the place to ourselves for at least two days, maybe up to four, depending on how long they plan to lounge around."

Krys tore her gaze away from her older sister and walked into the kitchen for a soda while Jade hopped into the seat shi just vacated and said after her, "Well Krys if you don't stop growing soon, you'll have to worry about stepping on us soon."

With an evil grin Krys walked back to the sofa with hir drink in hand. "Ahhh, don't worry, I would be a gentle giant." Then with a giggle shi placed the soda down and sat hirself down on Jade's lap.

Jade yelped loudly as the immense weight settled on hir and shi struggled to get out from under hir much larger sister. "Oh gawd Krys, get offa me!"

Jade groaned as Krys started laughing and wiggling hir ass, pressing Jade deeper into the sofa. "Awww is my big sister getting squished?"

With a growl Jade reached around Krystal and gripped hir breast into a paw and used hir fingers to pinch hir nipple. With a loud shriek Krys leapt off the sofa and looked back at Jade with a snarl. "What the fuck Jade? I was only playing, I wasn't going to hurt you!"

"Well it's not fun having over three hundred pounds of vixen sitting on me!"

Krys' snarl turns into a menacing grin as her eyes drift lower, and in a sing song voice shi replied, "Ohhhh, it looks like it was to me." Shi pointed to hir sister's pants.

Jade looked down and gasped at the erection stretching out hir pants. Shi shrieked as shi is pressed back onto the sofa with Krys leaning over hir, a very cruel smile on hir face. "Well, well, well it seems I turn my big sister on."

Jade started stuttering back, "Wha, wait, no, It's not what it looks like!"

"Oh it looks like you're hard from your lil' sisters ass rubbing against you." That grin of hirs somehow managed to spread wider as she said hir next words. "Just like you wrote down in that journal of yours."

Jade froze, hir eyes going wide and hir mouth dropped as she stammered, "Wha, wha, what do you mean?"

Krystal leaned hir muzzle so close to Jade's ear shi could feel hir whiskers, and shi whispered, "If there's something secret you want to keep on the computer, you really should remember to log off or anyone can walk up and use your account." Krys grinned as Jade shivered under hir as shi wrapped her head around the fact that hir sister knew every fantasy and dream Jade has had for over a year. "I have to say, you have some... frisky stories sis, I blushed reading a few of them. Oh and you got a few of my... um... dimensions wrong."

Shi giggled as Jade started pulling hirself together to ask, "So...what now?"

"Well, I really liked a few of your stories and I want to try living them out," Krystal replied, then pressed hir muzzle against Jade's, forcing hir tongue into the smaller vixen's mouth. Jade's arms wrapped around Krys' neck and pulled hir closer, into a deeper kiss. Krys' own lopped around Jade's waist and effortlessly picked hir up and carried hir to hir room. She laid the smaller vixen down onto the massive bed and climbed on to straddle hir waist.

They broke the kiss, both panting lightly as Krys said, "I thought my room would be better since I have a bigger bed." Shi pulled hir shirt up over hir head, freeing hir massive EE sized breasts.

"Perfect," Jade commented as she watched hir sister's huge tits bounce free. She sat up and latched hir muzzle to one of hir nipples, sucking and licking it like a nursing kit while hir paw moved to the other breast, rubbing it tenderly. Krys moaned loudly and rubbed hir sister's hair and ears as the smaller vixen shifted to the other breast, sucking and licking while a paw rubbed the one shi just let go of.

Jade murred lightly as she felt hir sister's supple flesh beneath hir fingers and hir plump nipple in hir mouth. Hir brain was on overdrive. First shi was scared that hir journal had been discovered, but now she was elated and lust filled as shi was finally in bed with someone shi had lusted over for almost a year. The fact it was hir own sister never bothered hir, it just made all the images and dreams that much more erotic.

Shi was shocked out of the kiss when hir sister tore at hir shirt, ripping it off of her and freeing her DD sized breasts. Shi moaned loudly as Krys latched hirself to a nipple and sucked on it while hir massive paw rubbed and massages the other breast, hir fingers playing with the nipple, clearly returning the favor from Jade's own ministrations. The older sister rubbed and scratched Kry's ears and hair as the bigger vixen sucked and nipped at hir nipples.

Shi groaned softly as Krys broke off from hir breast, panting lightly and again destroyed some of Jade's clothes by using hir claws and strength to rip hir pants off. Shi looked lustfully over the now naked vixen underneath hir. Hir paws slid down hir smooth flat stomach, claws dragging gently across the fur, down to the skin. Jade gasped as a large paw stroked up against hir sheath and cock.

In return, Jade placed hir paws on Krys' groin and rubbed at the thick, growing bulge. Happily panting, Krys moved hir paw from Jade's cock to hir pants and started hastily removing them. Shi let out a groan of relief as hir semi-hard cock sprung free form hir pants. Jade gasped as shi saw that huge black cock for the first time.

Krys couldn't help but giggle at hir sister's expression "I told you some of your measurements were off in those stories."

The silver vixen threw hir pants off of the bed and returned to rubbing Jade's cock, sliding from the head down the entire sheath and rubbing hir balls, grinning as shi watched Jade writhe in pleasure. Shi shuddered as Jade's paw gripped hir cock, hir paw not able to circle the thick girth, and started pumping up and down, making it grow and harden with each pump.

With surprising strength Jade shoved Krys over and onto hir back, straddling hir legs. Shi gripped the teen's monster cock in both paws. "God Krys, I always knew you were big but I had no idea this big. How large is this monster?"

With a giggle Krys replied, "Twenty inches last time I measured, maybe a few centimeters longer now. It's been growing a lot and fast, just like me since I hit fourteen. They say it's part of having hyperism."

"Twenty inches," Jade said dreamily, "there's a lot we can do with that." Shi opened hir muzzle wide and took the head as far in hir mouth as shi could, sucking on it like a popsicle. Krys leaned back on hir arms and moaned loudly as hir sister sucked on hir cock. Jade shifted and pressed hir pink and white cock against Krys' starting to thrust hir hips back and forth, rubbing their cocks together. Both of them shivered from the feeling of their hot shafts frotting against each other. With a loud slurping sound Jade broke off of the cock, strings of drool trailing from hir muzzle as shi took deep gasps of air. "I never imagined you were this big. There is something I've dreamt of doing but I didn't think you would be big enough. Sit up and move to the side of the bed for me."

With a sly grin Krys did as shi was asked while Jade hopped off of the bed and stood in front of hir. Jade smiled and gripped krys' cock and lifted it so it was level, but found shi could not hold it steady with only one paw. "God this is heavy, hold this here for me Krys."

Krys' grin remained on hir muzzle as shi gripps hir cock in a paw and held it steady. "If you think my cock is heavy you should feel my balls, I haven't pawed off in almost a week, I'm fixing to pop."

Jade froze and looked at hir sister "A week? You paw at least four times a day..... were you planning this?"

Krys' grin widened, showing off every tooth in hir muzzle. "Of course I've been. How else do you think you went to a movie the day the rest of the family went out of town and left their fifteen and nineteen year old daughters at home alone? I told them you have a lot of school work and that I didn't want to get shoved in the back of the van for a few hours."

Jade shook hir head. "You have always been the troublemaker."

"Proud of it. Now weren't you about to do something you've been dreaming about?"

Jade snapped back into focus on the tasked at hand and grinned. "Ya, you'll love it!" Shi gripped hir seven inch cock. "I've never been this hard in my life," shi noted as shi guided hir length to Krys' twenty inch monster. Shi pressed the tip of hir cock against Krys' urethra and with a deep breath to steady her nerved, pushed hir cock into Krystal's. Both herms gasped in delight at the intense sensations running through them. Jade thrusted hir hips forward and in one surprisingly smooth motion sent hir entire cock deep into Krys'.

Krys looked down at their joined shafts, delightfully impressed. "Wow, I never thought about someone fucking my cock. It's incredible!"

"I know," replied Jade. "It's amazing, I've always wanted to do it, and not only are you big enough you're good and tight too!"

With a grin Krys reached a paw out to Jade's balls and starts rubbing them. Jade shivered from hir sister's touch and felt hir knot starting to form inside of Krys' cock. "Oh god Krys, I'm going to blow!"

The silver vixen moved hir paw behind Jade's sack and pressed two fingers into hir cunny, working to bring hir to orgasm quicker. Jade gripped Kyrs' shoulders and with a happy whine hir balls tightened and sent waves of hir cum down Krys' cock. Shi watched as Krys' cock swelled slightly from the cum being forced down it, hir knot keeping it from seeping out.

Krys smiled at hir panting sister, moving a paw to hir own aching cock. "That was hot sis, but now it's my turn. And with that knot of yours holding you in I hope you're ready for some swollen balls." Shi started pumping hir cock, feeling hir own climax building at the thought of cumming down hir sisters cock. Jade grabbed hir sister's head and pulls hir into a deep passionate kiss, starting to thrust hir hips, sending more shivers up both of their spines.

Krys moaned deeply into the kiss as hir balls tightened, preparing to empty their load into hir sister. Jade's paws slid down to Krys' breasts and pinched the nipples, pushing hir sister over the edge. Krys howled into Jade's muzzle as hir cock throbbed and sent wave after wave of thick vixencum down hir length. Jade groans as shi felt the torrent of cum hit hir cock and start flowing down hir cockslit, shivering as hir sac started swelling with Krys' seed.

As hir climax tapered off, Krys pulled Jade onto the bed with hir and hugged hir close, waiting for the knot to deflate. "That was awesome Jade, I look forward to doing that again."

Jade murred and nuzzled Krys' breast, sucking and nipping at the nipple, feeling hir knot start to deflate, and gently pulled hir hips back to test the tie. Krys groans as Jade's cock slowly slid out of hir cock with a loud, wet pop. Jade sighed as shi was rolled over and Krys straddled hir again. Hir arms were pushed up above hir head as Krys licks and nipped at hir neck. The smaller vixen gasped as something suddenly wrapped around hir wrists. Hir head snapped up and shi saw a strap wrapped around both hir wrists and disappear underneath the mattress. Another feeling around hir ankles snapped hir head down, while shi was distracted Krys had tied hir to the bed.

Krys whispered out, "Much better."

"Ummm, Krys, why am I tied down?"

Krys giggled and kissed hir nose "I need to make sure you don't get away. After all, this is the part I was planning for. I'm going to stretch you out with my cock then fill you up with my seed."

Jade cocked hir head and smiled. "And you think I would have a problem with that? I would actually be annoyed if you didn't."

Krys grinned evilly and hir eyes took on a sheen that caused Jade's smile to falter. "I told you, I have been planning this for a while. Do you think I made sure the family was gone for a few days just for this? No, I have another plan in store for you. I'm going to do to you what I did to mom."

Jade's look of confusion deepened. "What did you do to mom? The only thing that has happened to her recently is..." Hir eyes widened and shi stared at hir sister. That evil grin remaining on hir muzzle.

Krys finished hir sentence, "Getting pregnant. And before you start going on about not being in heat I thought of that. You are the only one that drinks that tea so it was simple to add another ingredient to help your cycle along." Jade started struggling against the straps "Krys wait, why did you get mom pregnant and why do you want to do it to me?"

Krys rubbed hir paw across Jade's breast as shi replied, "Well for the reason you said earlier, if I keep growing I will out grown everyone and I want some kits before that happens. I can have some later if I want to be the mom but I want to father some too. With those drugs I gave you I am hoping to have an entire litter up to 4 kits."

Jade whined. "I don't know if I want kits, Krys."

With a giggle Krys replied, "That's what the straps are for silly. Now don't worry, mom and dad know and love the idea, after all they always wanted more kits around the house." Shi climbed up ontop of Jade and guided hir cock to Jade's femsex and pressed hir head against the lips. Hir hips started to slowly press forward, spreading hir sister open, stretching hir around the incredible girth. Jade gasped as shi was stretched, feeling the massive cock start to enter hir. The fear of being bred was quickly being replaced by the waves of pleasure filling hir. "See sis, you'll love it. Mom writhes under me when I take her."

Jade squirmed and gasped, feeling more of that huge vixencock filling hir, inch after inch stuffing hir like a thanksgiving turkey. Krys moaned as shi bottomed out in hir sister, hir entire cock stuffing the smaller fox.

Jade started to plead. "Krys, please take off the straps, I want to have my paws on you while you take me."

As shi started to pull out and press hirself back in the younger sister replied, "Hmmm I don't know. Convince me you want it."

With a whine Jade said, "Please Krys! I want to be untied while you fuck me."

Starting to build up a rhythm Krys asked teasingly, "While I do what now?"

With a cry Jade screamed, "Untie me so I can ravage you while you give me your kits!"

With a grin Krys quickly released the straps and Jade wrapped hirself around hir sister, hir mouth going to Krys' mountainous breasts licking and nipping at them. Krys moaned, "Oh my, you are really into this, don't worry we'll be doing this quite often." Hir thrusts started speeding up as Jade suckled and nipped on hir breasts. "Get ready Jade, you're about to become a mom."

Jade's grip on hir sister tightened as the thrusts of the twenty inch foxcock become like a jackhammer slamming into hir. With one final thrust Krys threw back hir head and howled so loud it vibrated Jade's entire body. Jade gasped as the cock inside of hir swelled and a huge torrent of thick, fertile foxcum poured into hir, each blast so strong shi could feel each one inside hir rapidly bloating womb.

With a groan Krys rolled onto hir back as Jade laid on hir stomach. Hir knot kept them tied together as cum continues to flow into the smaller sister. 'See Jade, told you you would love it. Now let's take a nap."

"I agree," replied the smaller vixen as she laid hir head down, hir ears picking up Krys' deep heartbeat. Shi slowly started to fall asleep as Krys closed hir eyes. Both passed out in each other's arms, tied together by the massive cock between them, both dreaming about the fun they would have over next few days that they had totally to themselves.
