Twin Trouble

Twin Otter OCs Oneshot

"I can't believe what that arse was saying... like I just leech off you for fun and don't do anything around the house... what do I do all day but study and do the housework... speaking of which, remind me to move the sofas when I hoover tomorrow, I can still see that idiot's breakfast crumbs on the floor." Isabelle was on her hands and knees, her arms resting calmly over her study book and she heaved a sigh of frustration as she flicked her shirt back a little more as her chubby body rocked on her knees. Her tail was to the side and she couldn't help but give a sudden moan of delight as she felt the heat within her body building and her body was stretching out with the pleasure in the base of her spine. "Aaah... a little more to the left Isaac..."

"Izzy... can't hold out much more..." Isaac groaned; his arms wrapped around her chubby hips as he could feel himself coming to the end, his hard cock buried deep within his twin sister's back passage, enjoying it squeezing and pulsing around him. It was getting tighter the closer she was getting to her orgasm and Isaac was feeling his groin burning and pinching with his approaching end, groaning as he dropped his head onto her shoulder and Isabelle gave a soft grunt of irritation that he was putting too much of his weight on her, but Isaac didn't care, he was so close and it felt so good!

Somewhere outside the large apartment building was the sound of cars pulling up, the familiar close of a door and immediately Izzy rolled her eyes and then turned slightly to stretch a paw back and smack her brother's hand. It was the usual sign to get off already, they were on the second floor but their roommates would be up in less than five minutes with the elevator and her situation was harder to hide than when he could just pull his pants up! As she gave a soft growl of warning to the otter still thrusting and groaning loudly as he pushed into her backside, her firm tail swung and slapped his hip urging him to give off and Isaac gave a groan.

He hooked his arm around her pulling her up against his stomach and onto her knees as she gave a groan at how his suddenly seemed to slide right onto the best spot within. She groaned, how was it he had to get to the good point now? Isaac then pulled his twin sister up onto her webbed feet, beckoning her to stay still and against him as he continued to grind into her and then pulled her back towards their bathroom. They backed off towards the toilet, turning around a corner of the wall to get out of the view of the others as he continued to thrust into her as she was groaning and leaning forward. He was really hitting the best spot in her body as he pushed her right up against the wall beside the door, stretching himself out and bracing his paws against the wall as he groaned and panted to keep getting into her.

Just as Isabelle began to panic about the possibility of them getting caught by the jerks that were always complaining that she didn't do this or that, Isaac hooked a paw against one of her plush bosoms, squeezing it tightly as he came. She gagged a little, holding her mouth shut against the squeak as she felt his seed spilling up into her backside as he thrust just a little more, his cock wiggling inside her before he gave a groan. He dropped a door, popped the door handle down and then as it fell open, he pushed Izzy straight in as she gave a swear, his cock sliding right out of her sodden backside before he hooked his pants up around them. He closed the door as she fell onto her knees within, stepped towards his bedroom and scratching his backside as the front door open and their four other roommates marched in.

"Hey Zac... you still not dressed? God, your sister let her work on the floor, again! She's got a desk and everything in her room..." The female mongoose, the only other female sharing the accommodation, gave a groan of frustration as she stepped over. She was grinning to look at Isaac with his cock still not shrunken down completely and pressing against his trousers. She was a female that was after Isaac like quite a few others, but the problem was she always wanted a full on relationship and Isaac did not want that, he was content with quick flings so he didn't have to worry about upsetting someone's feelings just because he said someone else looked good... but this mongoose was always on about Isabelle over something because she was the only girl that got Isaac's full attention.

"She's just gone to the loo; I was sitting with her helping her out... I don't get it though, the stuff she studies is on another world to me..." Isaac groaned, grabbing at his crotch a little to make it more comfortable before stepping out to his room, giving that girl a little show as the other guys were busy unpacking the groceries and Isaac was content as he reached his bedroom. He closed the door and then slumped onto his bed with a soft wheeze of relief before he dropped his hand down to look at the mess within his trousers. He was so lucky he'd managed to blow his load inside her before these guys had gotten back, but he'd still not managed to get it all out before he'd pulled out. He pondered if there was going to be some kind of stain on the floor or wall that one of them might spot, but hopefully that wasn't the case. But he chuckled softly as he considered that tonight he'd have the drop Izzy her money towards the rent.

Isabelle was on her knees, groaning in frustration but trying to keep the sound down as she felt the cum sliding steadily out from her taut backside as she squatted on the bathroom floor. Her brother was so fucking lucky that this place was easy to clean, but she couldn't believe that he'd decided to let himself off no matter what and not just sneak in the bathroom so she could get her orgasm. As she felt it still sliding out and knew it was better to let it get out by itself before she started wiping it out, Isabelle grit her sharp little teeth as she thought about what she was going to do tonight. When her brother got in the bed, he'd better get her off otherwise he'd better pay her double! But that made Isabelle grin to herself... what would all those girls that were after her brother think if they knew his little kink of dropping off some cash after a good fuck - it certainly made things easier for Isabelle!

That evening the conversation was bobbing about the question of rent and everyone's contributions for the month, which always irritate Isabelle because they tiptoed around the arrangement before turning to her and then questioning just what she was going to give them that month. To be fair, she was only a couple of dollars short of the main contribution, maybe a ten or twenty out, but when she announced this, the others were quick to groan over the idea that she didn't have what they needed then and there. Isabelle gave a soft expression, she was saddened at the words and actions as the other grumbled at her, before Isaac gave a grunt.

"Hey... Izzy does all the cleaning in this place; she even sorts the trash when none of you clowns will! You should be appreciative of the work she does... anyway, I'll put in the extra she needs, its only a ten so anyone of us could easily cover it..." Isaac stated in a grunt of frustration, turning to pat his sister's back softly in affection, smiling towards her like any protective brother would his twin sister as the others looked uncomfortable. They knew he was right about it, they always seemed to pick on Isabelle at this kind of situation, but Izzy gave her brother a gentle hug to him before she turned and looked at the others pathetically as Isaac held her hand. "Besides... she doesn't steal your food, she uses my computer, she uses my stuff not any of yours, so really she's just borrowing from me and any brother would look after their sister like this, right?"

"If might be easier if she got off that fat toosh and found herself a job..." The mongoose hissed in irritation, but straightaway, the otter brother turned around to stare at her harshly as Isabelle duck her head down, looking sorrowful and upset. The others grimaced, they knew it was a sensitive subject and quickly they insisted that it had been uncalled for and that Isabelle did do the cleaning they were too lazy to! It seemed to silence the remainder of the conversation, but it was clear that Isabelle was going to have to somehow pay her whole amount and that was fine... she knew how to do that without any trouble.

The rest of the evening continued on without conversation, they watched a movie together and of course, Isabelle made a show of how useful she was by actually cooking a good dish for them all. It seemed to shut the mongoose up, but she spent a good part of their dinner trying to wrap her tail around Isaac's leg and acting as if no one noticed it. Isabelle noticed and though she couldn't quite give a flying fuck about whether Isaac was going to shag her or not, he could if he wanted, but considering she'd been so mean it had been annoying. Isaac though had ignored her completely, he didn't like girls that tried to hard to get his attention, he didn't like that kind of subtlety or the way they were coy about it... he liked everything straightforward and that was why he liked it with Isabelle.

With her there was no fuss about emotions, relationships or complaints about whether someone actually wanted to do the things he wanted to do... plus she was utterly open to anal whereas a lot of females got funny about it! Things with her were perfect and when it moved on into the night and everyone was tucked upon in bed, Isaac slipped out from his cover and grasped his wallet. He opened it up, pulled out a twenty and then he closed it and put it away before strolling out of the bedroom on his way to see his sister.

As always when she expected him, Isabelle left the door unlocked and was rolled to face the wall in her small closet of a bedroom, her underwear off and nothing but a loose-fitting shirt on. She had made sure to give herself a quick enema before bed, liking everything to be smooth and clean for him so they could just enjoy themselves. As she snuggled down into the sheets, she saw the thin line of light slowly open up with the door before it closed off and someone slid on slapping webbed paws to her bed. The chubby little otter-maid sniggered to herself as she felt the cover lift and then her brother's face came to hers for a loving kiss before she lifted a paw.

"Ah... rules... if its work then there's no kissing or cuddling!" Isabelle teased her brother as he froze for a second as he leant over her and then gave a soft chuckle of amusement before whispering that only got him harder. As he slumped back down into the bed behind her, he pulled his pants down to show he was getting a little hard as the warmth pressed into her back, before he strained his paws forward to grasp at her plump bosom and began to massage them. As she gave a soft groan of pleasure, she started to move her hip, grinding herself into her brother's groin as he gave a shudder of pleasure and his long hot rod began to slip free of the sheath. With it growing, Isabelle pressed close, clenching and releasing with her backside so that his form could slip right between the cheeks and then he was grasping her and shuddering in excitement.

"Keep grinding into me like that... I want to be close to bursting before I stick it in there..." Isaac groaned in pleasure against her, feeling his form sliding back and forth between those warm cheeks and tempting him to just shove it right in. But the way she moved, the way she was able to clench and squeeze him a little as he rubbed between was exhilarating. The pressure mingled with the pleasure, the friction urged him to swell and he could feel that want in his hips to thrust hard but he kept his cool. His sister's breasts felt good too, squeezable and malleable, they were like memory foam cushions in his paws and just so warm he could squeeze them almost as much as he loved to squeeze her arse. They continued to rub and grin into each other, the hole getting wet with anticipation as precum began to form on his tip, he could get off quick but it meant he could get off more than once and it made Isaac shudder as he pressed his forehead into her back and grunted. "Wanna stick a finger in first, just to feel its all good..."

"You're buying so do what you wish..." Izzy sighed pleasantly, feeling her brother suddenly shudder against her in excitement to know that she was giving him permission to play this out like his preference. Isaac couldn't explain it, there was just something more thrilling and pleasurable in using sex as not only a business transaction but rewarding a good time with money, it made him feel exceptionally powerful and able to give absolutely anything and everything as long as his cock was worshipped. It was probably a little sadistic, but he loved it all the same and he slid his paw down to the crack, rolling his hip back to releasing his form as it was getting wet and slippery. He shifted a digit between the cheeks, feeling Izzy lift her knees to let it open up more as he then stroked around the puckering ring that welcomed his digit probing it with curiosity before he even felt it open out for him and he grinned.

"Perfect..." It was so warm there, it felt so good to just roll his finger around in there, to feel it widen and get wet and tug him in. Knowing it was warm enough and stretched enough for him was wonderful and Isaac grasped his sister's waist gently, pulling his paw away to make her gave a sharp little gasp before he angled himself. He pushed his tip against the hole, probing the pulsating ring that pinched in and out, almost teasing him to just stuff it in as he gently brought his hips up against his sister's. He felt his form barge through the tight opening and into the damp heat, he felt the passage convulse and grip around him, pulling him in further as his breath shuddered as he eased himself right inside her before giving a soft groan of pleasure. "So tight... so good..."

"Surprising its so tight, this is your third time today!" Izzy teased as her brother just sighed and fawned softly at the heat, the tightness and then way she clenched to let her insides roll around him. For her that feeling was a little more different, it was strangely fulfilling, almost as if satisfying a hunger and where it had burnt before, it was now comfortable and he always buried himself in deep enough to make it feel good. She chuckled as he shuddered, clenching the muscles around him to make him gasp a little before she dared to rock her body and he almost slid out. Quickly, he grasped her waist and pulled her back against him, not wanting to leave the warmth of her body and steadily, he began to grind and roll his hips against her body. He kept in a deep position, pulling back only slightly, knowing the angel to rub at to make Izzy give a soft sharp sound to say he was touching a good spot. He grinned to himself, gently pushing her hip to make her roll onto her stomach and with a grunt, Izzy managed it.

As he straddled her, he managed to keep himself lodged inside and now he was above her, he squatted and gently dipped himself in and out. Letting himself come out more but then stuffed it back in slower to make Izzy gasp and her ring pucker and pinch, vibrating around him with sensation. He sucked in air through his teeth, licking at his lips for the pleasure of just dropping all his weight in between her plump buttocks as she grasped them with her paws to spread them for him, moaning softly in delight. Isaac was really enjoying this, feeling her getting not only wet with his form inside her, but feeling the little bubbles of precum clinging to her body and making it slicker as he gave a groan.

"So what's your plan tomorrow? You've got morning lessons like me but then we've got a free period... want to meet up here for lunch? I'll make sure you get a filling meal..." Isaac grinned, drooling a little onto her shoulder as he squeezed at her breasts and grinding his form within hers. It was so tight, she knew to belly roll to get the muscles to shift up and then slip down, filling the area with constant new sensations for him as he began to slowly thrust himself into her as she gave a soft moan of appreciation. But her tail clapped at his leg a little, that was so typical of him to say something corny about sex when they were in the middle of doing something. She hated it, mainly because she feared he was forgetting that this was for pleasure and arranging times always seemed a little too much like dating. But he continued to thrust in, this time a little faster as he felt the pressure building up inside him.

"You better put more work into it... I can hardly feel you back there..." Izzy teased him, making Isaac growl slightly as he dropped his paws back down to her thighs. His slight webbing between his digits clung to her sleek fur as she dropped her paws onto his, beckoning him to start hammering into her. Izzy didn't like the slow grind, that was only for days when they had the place to themselves... she needed it quick and hard so she could get off and that was that. Isaac groaned as he felt himself coming close to the end, hooking about her hips even more tightly as he swung his hips back, almost pulling out completely before slamming forward to make Isabelle give a cough of shock.

With her facing the headboard and their positions enough to say the drilling needed to stop, Isaac pushed down firmly and then began to slap himself into her body. She gave pants and wheezes, catching her breath fast as Isaac began to clap his body into hers as hard as he could, groan and pushing her hips up against his body with each thrust. He felt himself stuff in deeper, the resistance hold for a second before giving in to damp pleasure as he then pulled back only to dive in again. He felt her body squeeze him to get in deeper and he pushed in as fast as he could, feeling the pleasure in forcing her body to open out and then roll against him, cling to his skin to make it tingle with excitement.

"Ugh... fuck... gonna cum..." Isaac hated it when he came before he wanted to, but Izzy seemed to roll her eyes in frustration for not getting off first, but Isaac started to really pump shallowly into her. He groaned and bit down hard, grinding his jaw as he tried to hold back cumming until he just hit the right point in Isabelle to make her start to gasp sharply with the building pleasure. He tried harder and harder, rubbing into the part that tingled the must as her body pinched and pulsed tighter around him before he felt it get wetter and then when Izzy gave a sharper moan, her jaw dribbling, he was able to release. With a sigh of relief as he slackened and seemed to sag down over her, his cock spewed his load into her passage in a thin spray, mingling with her own pleasure as he sighed and then gently wiggled his hips just to make sure it was all out. "I probably should have used a rubber..."

"No need... I can go across the bathroom and clean up... they're all dead asleep anyway..." Izzy sighed as he slumped down against her pillows and she rolled around the face him. She pulled out her draw, taking out a little candy from the drawer and slipping it into her mouth, the sweetness making her moan with even more delight. As she settled down, ignoring the tickling feeling of his cum dribbling out onto her sheets, Isaac then swung about to lay a twenty in her drawer before he gave her bared breast a soft squeeze and she gave a grunt. "If we're about tomorrow, we're about, if not... we're not..."

"Got it... thanks for the quickie..." Isaac chuckled in amusement before slinging himself out of the bed and then stuffing himself back into his underwear before he strolled out and straight to the toilet for a quick whizz. For plopping the money down and just departing like that without another word... it felt good and made his body tingle and the linger pleasure of the orgasm continue as he used the bathroom. He really enjoyed that feeling of just plopping the money down and walking off like he was using some vending machine, it really made the feeling continue and yet Izzy was the only one who'd ever got it and let it happen. That mongoose was surely the kind to get offended by that kind of thing for sure!

Isabelle was at the house at lunch, during the morning she'd put the sheets on to wash as well as everyone else's and had just started putting them out on the line when she'd heard her brother turn up. Isaac dumped his bag in the doorway with a groan of relief after a boring lecture and he strolled right out to where Isabelle was busy putting up the dark blue bed sheet. The wind kept slapping it about her face and with everyone in the area out for the day and the blue sheet smothering the doorway... there was no way for anyone to see things and Isaac had a sudden idea.

He pulled himself out of his pants and walked right behind his sister, as she straightened the cloth out and it kept fluttering into her face, Isaac grasped her skirt and suddenly began to shift it up her chunky thighs as she looked over her shoulder at him. This was a little riskier, but it was certainly something she'd be into as she lifted her tail up to show that her reddened ring was still gaping and ready for him. It was too good to resist as he grasped her belly, steering her to press against the little balcony doorway as the big blue sheet smothered them from being seen. As she braced herself, bending her body, he let his cock bounce against her cheeks before he decided against anal and just decided to rubbing himself off between her cheeks. As he made sure to rub up and down the crack as fast and hurried as he could, Izzy gave a soft chuckle.

"This my reward for washing your fucking dirty shorts?" Isabelle teased, but Isaac gave a growl, he was still a little embarrassed about that, two days ago she'd been giving him a hard time when he'd been trying study. She'd gotten under his desk and managed to climb up to almost sit on him, but instead had been rolling and rubbing her soft backside against his groin. He'd tried to focus on the work, tried to ignore it all as he'd been working really hard on some tough calculations for his project when he'd felt his boner growing to the point it was about the burst. But just as he'd pulled back and pulled himself out, Isabelle had strolled out and giggled that she'd gotten bored and he'd ended up almost darting after her. However, being cheeky as Izzy was, she'd flicked her tail against his bare tip and he'd ended up cumming very heavily all over his shirt and pants! Isabelle chuckled as she thought over it and gently clenched to give him more sensation as she rubbed at him. "Not that I ever mind... but you wanna hurry and get off... I rather like going back to lessons with a cum stain on the top of my hips... makes the boys the smell it curious..."

"Oh really? Well... let me know if you're getting with anyone else and I'll make sure to stick with condoms whenever we're doing this!" Isaac groaned, leaning his hips in and rubbing against her soft flesh gently before deciding that he did deserve a little revenge this time. With her skirt covering her front and his mind considering getting that little payback, he shifted position. He stopped rubbing between her cheeks and instead pushed himself between her thighs. She gave a sudden gasp of shock, trying to drop down a paw to grasp her skirt and pull it up so it would not get messy, but Isaac just continued to rub himself between her thighs and then further up. As soon as he was higher up to slip between the lips of her pussy, she gave a sudden gasp of excitement as immediately, his damp cock rubbing against her and flicking at her clit made her pussy dribble in pleasure and make it even more slick and slippery. "Not my favourite, but pretty good..."

He chuckled in amusement as she gasped and groaned, trying to pinch her thighs about him tightly to stop him from doing it too much, but Isaac kept going with a grin. As she continued to gasp and shudder with her growing orgasm, her pussy getting so wet it was difficult to stop herself from moaning and sighing over the sensation as she couldn't fight and spread her legs just a bit more. This gave Isaac better access and her hurried to rub against her, his cock swollen to the point it felt like it was truly going to burst as he grit his teeth, sucking in air and then finally gave a sudden grunt.

"ISAAC!" Izzy snapped, his cum spurted forward, splashing onto the inside of her skirt with a big thick dollop that dripped onto the floor. She groaned as he decided not to rub her into an orgasm, but he slid himself back and then shoved himself back in his pants with a chuckle. As Izzy panted and then pulled her skirt straight off, annoyed her brother would do such a thing and then shifting her knickers up, she stormed to the sink to chuck it in and start to scrub off the cum before it got crusty Isaac was chuckling as he made himself a sandwich and lounged on the sofa. He watched his sister scrubbing away in just her panties, watching as her motions made the fabric slip in between her loosened cheeks and seemingly get eaten. He was only able to finish one triangle of the sandwich before his cock was throbbing and he had to check the time... there was only a little bit of time left but he was sure it would be enough as he hopped over to her. "Isaac..."

"Come on, you said I could always just go ahead if I was horny..." Isaac grinned wickedly as he started to rub his throbbing dick back against her backside, making her lift her tail for him again as she turned around to glare at him. She pointed towards the crusting mess on her skirt, but her held her hips and continued to rub up and down before he shifted a paw to the pocket of his shirt. He pulled out a ten, slapping it onto the counter top and Isabelle gave a soft chuckle before permitting him to go ahead and keeping rubbing himself off between her cheeks. He groaned in delight, he was really enjoying this, but his cock was throbbing with so much pressure that he knew he was not going to last longer. He rubbed between the warm wet cheeks, sighing and moaning gently as he ground his hips against her before he felt the pressure building and he slapped his paws to her hips and then gave a gasp.

"Thanks for the transaction... now get back to college you bum..." Izzy teased the moment she felt the hot wet semen slap onto the top of her backside. Isaac pulled back with a groan, quickly trotting to the toilet with a firm smirk as he watched Izzy straighten up and stuff the tenner in between her breasts. She then continued to scrub the cum from her skirt before giving up and looking for another after yanking her knickers back up. Isaac stepped out of the bathroom, hooked up his bag and then hollered out that he was going out with friends tonight and not to be expected till late. Isabelle waved him off and then shook her head in complete disbelief, her brother was such a pain!

Isabelle slapped the rent down in front of the others and gave them a firm look to say they weren't going to get rid of her that easily. The mongoose was irritable of course, annoyed that she couldn't get rid of the one being between herself and Isaac, who patted her shoulder and praised his twin for getting the money they needed. She blushed she'd gotten lucky with a friend that wanted to go over some study notes and Isaac couldn't stop beaming with how happy he was for his sister's accomplishments and it made the mongoose feel sickened by the otters. But as Isaac then set down his cash, beaming in delight, he got a sudden shock when one of the guys gave a sharp gasp.

"Hey Isaac... I was told you were being begged to join the college swim team again this year - you should do it buddy, you were a gold winner!" One of their housemates, a rather loud raccoon, butted in as he brought a can of beer to his mouth. Last night he'd joined Isaac in getting girls at one of the local clubs and having fun, but he'd been socked when it was clearly the otter's athletic skills that the girls had all clambered for, rather than his ingenuity. Isaac had given a groan at the response, currently he was too busy doing actually swimming lessons for the old and working as a life guard at the pool for half-days Wednesdays, Fridays, Saturdays and Sundays that he had no time to do anything else. He looked towards the racoon with a face that clearly said he had no time with that and college and yet Isabelle gave him a sudden nudge with her elbow, insisting he could probably give up a bit of time on a Sunday morning to do training or his lesson gaps that he shared with her. The moment she said it though, Isaac turned around to stare at her in confusion before giving a groan and just grunting that he really did not have the time as he walked off to his room to do his studies.

Isabelle left him go and continued to socialise with the others, actually trying to be nice with the mongoose this time but finding that in the end, that girl wanted it to just be her and Isaac... fat chance. As she spoke with the others, she learnt that the three of them were off to a convention for the weekend in the next town over so the house would be empty. The racoon grumbled that he'd intended to ask Isaac to come as it was Isaac's weekend off, but Isabelle insisted that her brother was saying the truth in stating that her brother needed to study. But when she thought about it, she was just musing that their departure would give them both a little time to just get rid of their horniness just a bit more to let them settle after the past week of getting in each other's face over their randy desires and lack of time to do anything!

That night, she could not sleep because she wanted to tell her brother the good news and knew he was likely to be asleep in bed by now! She snuck out, slipping over towards the bathroom in case anyone spotted her before she reached her brother's room and opened the door. She was thankful that he had not locked the door, since her teasing last time he'd been locking it at night so it seemed the incident the other day had made them even indeed. As she slipped into the bedroom, she padded over to his beard, hearing him snoring away and she shook her head in disbelief... how could he sleep so soundly like this? With a grunt she waddled over to his bed and yanked the cover off, finding him sleeping naked for once and she was grinning about it!

"Oh... brother you are such a treat..." She knelt onto the bed and slid onto her side, groaning that he never made enough room for her as she squished down and rolled into her belly with a grunt. Fearlessly she hooked up his cock and rubbed gently at the sheath to lure the pink face out. Isaac groaned slightly as her webbing clung about his sheath, kneading it slowly so each knuckling motion came with the extra friction from the webbing as he strained out more with a sigh. She chuckled to herself, licking her lips and then lazily rolling her tongue around his head, making it twitch and swell as he moaned more. She snorted gently at his reaction then tenderly she hooked her mouth about him and drew him in to fill up her chubby cheeks.

As she slurped and moaned, tail flicking to the side and wagging slightly to try and see if she might rouse his attention. Giving him a blowjob was a rare treat, something she only did when she felt guilty about something and well, that guilty sensation had stopped her from sleeping. Normally, being unable to sleep was the most open way to leap into the bed with him or him to her and have a quick bit of satisfaction to knock them out. But on this occasion, she was musing about the idea how he'd walked off before hearing the rest of the conversation and she moaned softly as she suckled on his cock. She bobbed her head back and forth, feeling his head throbbing and spitting precum before she heard a sudden groan from her brother and then suddenly, paws clung about her hips.

Her tail went up, her face in a delicious and wicked grin for the fact that her brother was suddenly pulling her onto his body as she gave a groan and let him lift her. Her chubby belly pushed into his stomach along with her breasts, putting pressure below as she continued to suckle away and he gave a groan of pleasure and brought his rounded face to her backside. His tongue flickered and rolled around her ring, making her pretty little pink asshole pinch outward eagerly as he continued to lick and slurp in response to hers. She gave a soft sigh of pleasure against his cock, a hot blast of air leaving her lips to tickle his sweating balls before she pushed his cock into her mouth and to her inner cheek. Pressing it against such soft, slippery, warm flesh made him groan as he hurried to lick and slurp even more eagerly at her backside before he gave a groan.

"Get off... I gotta unload in you..." Isaac grunted... blowjobs were great, but finishing himself off inside that tight grasping ring was much better. Isabelle rolled onto her belly, backside right up with her mouth covered in drool as she started to slurp in and swallow the precum to have tickled into her back of her throat, Isaac was up. He brought his dribbling cock to her tight hole, swirling and rolling his cock around the tightening ring that tried to grasp him, glazing it in his precum to make his entrance easier. Isabelle gave a soft sound of pleasure at the sensation as Isaac adjusted himself properly and then grasped at her hips as he aimed his head into her hole making her give a sharp gasp as he pushed in hard and deep. "Fuck... I almost came then..."

"Try to hold out a bit... I just wanna a little fun..." Isabelle sighed cutely, but Isaac gave a grunt as if he didn't care and then gently he began to thump his body into her quickly, his hips clapping against her cheeks as he pulled back and pushed her cheeks together, making sure they squeezed him just as much. He groaned at the feel of that ring squeezing and clasping him, the way Izzy's body tried to clench around him and pull him in further as he groaned in pleasure. With his mouth open as he sighed heavily, tongue slipping out slightly, he kept thrusting into her and panting away as he hurried and hurried. His cock felt like it was starting to melt inside her, it was so warm, so sticky, so good and it made Isaac groan as his sister hiccupped in breath, feeling everything inside her getting rubbed and pulled about.

"Fuck... fuck... Izzy I'm gonna blow soon..." Isaac growled, he was really enjoying this, really loving it and as he continued on, he could feel that tightening in his balls and then it vibrating down his shaft to make him suck in air through his cute little nose before he gave a sudden grunt. He felt that sudden burst, that wave of pleasure slapping into him like a sledgehammer and he groaned in pleasure as he continued to thrust a little bit, squeezing out the last few splashes of cum as his felt his sister's asshole pinching and pinging around him in pleasure. He licked his lips in relief, it felt so good and he was very, very thankful for the delicious sensation before her groaned and pulled out, only to give her a gently kick to get off.

"You know Isaac... they're out this weekend, going to one of those boring conventions and that girl's going to her art club retreat... so, until the weekend, this is your last taste." Isabelle grinned and Isaac gave a grunt, making a sound as if he didn't need just her to satisfy him. But as she hopped off the bed, she turned about and suddenly pushed his cover over him, forcing him down and tucking him in as he gave a growl of frustration and she kissed his nose. As he glowered at her in frustration, she grinned and rubbed at his nose playfully as she straightened up and grinned. "You know... it only takes me to get a boyfriend and this is all over and lately... there's someone who interests me..."

"I get that, it'll be a shame but, it won't be a loss. As long as you make sure he's a good guy... go back to sleep now Izzy." Isaac grunted in frustration as he settled back into the bed and snuggled up within his covers. That was amusing, but even when they did have their partners, sometimes there was just too much fun to just play with each other, so he doubted it would be over that quickly. He smirked as he settled in, maybe he would hold it in for her for the weekend, maybe!

The weekend came and Isaac woke up with a groan and then slapped his feet off towards the shower, groaning slightly in frustration before stepping under the water. He scrubbed at himself, cleaning himself up and yawning into the shower as he heard the happy little sounds o his sister skipping around and doing the cleaning. It was midday already; he'd gone out drinking with the guys last night and he'd been celebrating a good grade on his latest assignment. Isabelle had done well too, but she'd mentioned something about giving him a surprise today and so, as she hadn't woken him up with a blowjob, he'd assumed it was something more substantial, like alcohol!

As he finished up in the shower, he hopped out and dried himself up, his fur cleaning up quick thanks to the natural manner of otter pelt, before he wrapped a towel about his groin and stepped out. He strolled out into the open air, a curious expression upon his face as he looked towards the little room and then spotted something that made his eyes widen in utter disbelief. Isabelle was finishing her washing up, she was cooking a cake for him in the kitchen, but she was wearing a pretty pink apron and absolutely nothing else. Her tail was right up, only the little knot at the back of the apron visible down her back as she flashed her hole towards her brother, and it was clearly glistening to say she'd been prepping for him.

Isaac was shocked, he strolled into the main part of the kitchen and found breakfast waiting for him, he settled down to eat up his meal in delight. He was eager to scoff it all down, it was great but his eyes were locked upon Isabelle's backside as she switched her tail and wagged her hips as she scrubbed away at the mixing bowl before she paused and then put things aside. She turned her head to the side, looking at her brother and twitching her whiskers in pleasure to try and pull him in as Isaac gave a heavy gulp. He was still shocked he'd managed to be able to hold out till the weekend and he was starting to feel himself probing against the towel and this was just too good a situation to avoid.

Swiftly, he was up off the seat and over to the sink as she continued to scrub away and he was right behind her, towel off and cock rubbing between her cheeks. She gave a soft moan of pleasure, leaning against the counter as his webbed paws clung about her bosom and he groaned over her shoulder. As he slid himself between the cheeks, getting the lubricant she'd been using on his cock, he was startled to feel something tingling at him. He could feel himself getting hotter too and his eyes widened in excitement... his sister had been using one of those tingling lubricants and it was making him swell faster as he rubbed faster and faster between the cheeks, desperate to get his full size quick enough to stuff it in.

"You cheeky thing... this is a naughty reward!" Isaac beamed into her shoulder, trembling in excitement as the gel was tickling and itching about his cock, making it twitch and swell in desperation to be buried inside her. With a soft groan, he decided he could not wait any longer to get inside her and swiftly, he pulled her tail up as she gave a soft gasp, bending with over and pressing her backside right up for him as Isaac stuffed himself right in. Her tailhole squeezed and clenched about him, almost unwilling to let him get straight in as he hurried to push in deep, moaning and sighing to feel everything tingling and pinching around his tender skin. He pulled back a little, rubbing gently round the ring with his cock, swirling that burning and tingling gel around it even more as Izzy began to moan lovingly and then she tried to squeeze outward for him.

He managed to push himself in deeply, pulling her backside into his groin to align them as he craned over her body, squeezing and massaging at her bosoms in utter delight. She shuddered and moaned, the gel had been making her insides pulse and pinch, clench and pull around his cock as she gasped for how good it felt. Isaac was trembling in pleasure, he didn't need to move as he felt that gel making her whole bowel pinch and squeeze about him, it was so good he just felt comfortable leaving his cock to sit calmly inside her body as he moaned and drooled slightly in total delight. However, the gel was making him get itchy, making him hot, he tried to hold onto his desire to thrust, just letting himself sit inside her warmth as he groaned and almost purred in total delight but he couldn't help it.

"That stuff's good..." Isaac groaned in delight, as he continued to knead and grasp at his sister's breasts, he started to rock his hips back and forth into her body, his tail straining outward as he moaned in pleasure with his tongue almost hanging out in total delight. He groaned as he pumped himself into her body, feeling it continue to ping and twitch as she clenched and squeeze around him lovingly. She moaned and sighed lovingly as Isaac hurried inwards, feeling nothing but pleasure drown all his senses as he suddenly released her breasts to hang onto the counter and just start banging his hips into her as she grunted and groaned in the pleasure and shock. It was good... really good... he was glad he'd been holding out but as he felt it getting slippery and slick within her, he could feel himself oozing and mingling with her own juices and the gel and he shuddered in anxiety that he might blow already. "Fuck..."

"Just let it out... it's not like we haven't got all day..." Isabelle hissed with a sudden lick to her lips as she groaned and sighed. He continued to hammer into her body, groaning and sighing in utter delight as he felt his cock swelling inside her tight passage. He groaned as the clapping grew louder around him, the sound of squelching and slickness making him groan lovingly as he rocked backward. He gripped his paws down to her hips, slapping himself into her as she gripped hold of the metal of the basin, groaning and straining out with her tail to fit him in more as she grasped the sink to keep them both stable. He groaned and shuddered as he slapped into her, feeling her clench around him, pull him in deeper and almost try to squeeze him into cumming already as Isabelle groaned in joy! "Come on... you can finish..."

"Don't wanna cum yet..." Isaac groaned, gritting his teeth and squeezing out the air between them as his ears pinned back, eyes pinched shut and he hurried to get deeper into her. He panted suddenly, his tongue slapping against the side of his mouth as he felt his balls clenched up and then that tingling gel tickled him enough to reach his end. With a sudden squeak he managed to produce a firm spit of thick cum that boiled into her backside as she shuddered and gasped in pleasure. Isaac groaned in delight, sighing and heaving as he pulled out and grasped his cock, pulling it straight out with a wet pop before groaning and slumping back onto the floor with a shudder. He panted gently, mouth open wide as Isabelle finished up washing up and then gently she poured out the bowl and added some soap and warm water before grabbing a fresh wash cloth, lifting her leg up and then swiftly cleaning up her backside for a little while as Isaac remained lying on the floor.

"I hope you liked that... but now the cleaning's done... how about a change of pace, big brother?" Isabelle grinned, licking her lips gently in amusement before strolling over to him with a soft chuckle and grasping something from the table, a big squidgy bottle that she squeezed down onto her groin with a chuckle of amusement. Then she smeared and teased it into her pussy, filling it with the lubricant and wiping it about her body, stretching with her fingers to widen it out as she approached her brother. Isaac stared up at her in curiosity, it was rare she let him go in 'that' hole, but it was not his favourite. As Isabelle also pulled over a condom, she then knelt in front of her still steaming brother as he panted and lay back with a sigh before suddenly she grasped his cock. "Let's make this fun..."

Isabelle gently began to pump his cock up and down, forcing the sheath to slip downwards as she pumping the long form until it began to straighten and swell. He groaned and sighed in pleasure, his tongue rolling around his lips in pleasure as the motion smeared the tingling lubricant down his cock again. Isaac groaned in pleasure before the condom was then sat over the head of his cock and she pinched her lips around it. With her tongue flicking and tugging, she rolled the condom right down his cock as Isaac shuddered and his hips gave a sudden jolt of delight as she rolled it out. When she then stroked it with her paw, ensuring that it was certainly suitable for her to ride, she bent forward and kissed his nose tenderly before she straddled him. One paw lay on his stomach as the other held up his cock and with a wheeze and a push outward to her lower body, she opened out to let the covered cock slip right up into her tight pussy.

As Isabelle gave a gasp, Isaac gave a soft groan and then grasped her hips - he was about to grumble that he wanted to get it over with quick, finding this passage not as tight until she patted his nose. She then grinned and started to lift her body up and down, panting gently and stuffing his length deep into her damp warmth as he groaned and sighed, her bodyweight pushing against him and making is groin tighten pleasurably. She sighed as she continued to ride him, licking her mouth and then her nose as she continued to lift up and down, not letting their bodies slap too loudly as she seemed to be in some strange kind of control over the situation. It intrigued him as he groaned and sighed lovingly, just enjoying the friction against his body until Isabelle gave a groan, seemingly wetting herself with an orgasm from his cock in her pussy before she could feel his cock pulsing and getting very close to cumming and she grinned.

Suddenly, she pulled herself off of him and then bent down as Isaac stared at her with a gulp of utter disbelief. He then grimaced in fear as she brought her teeth to the bottom of his throbbing cock, fearing she was going to bite him as she pinched her teeth around the bottom ring of the latex. She then chuckled as she pulled it right up, knocking it so Isaac gave a groan and almost felt like cumming just to see her doing it this way! Isabelle grinned before she straddled him again and this time, stuffed him back into her tight backside as Isaac gave a groan of utter delight. Isaac then grinned at his sister, licking his lips and then leaning forward to grasp her hips and slam her down onto his cock as she jolted and hiccupped in total delight.

Isabelle groaned and sighed, panting and heaving as her tits and her belly bounced about as her brother began to thrust upwards with his hips. He was amused, she'd tricked him completely and now was going to let him jizz inside her ass again. He groaned and crooned, very close to coming again as he let his hips thrust upwards, filling the room with their clapping flesh as both of them began to sweat heavily. Isabelle's eyes were filling with tears as she groaned and sighed lovingly, so close to a really big orgasm of her own as Isaac hurried and hurried then suddenly he stabbed right up into her, her body clenched about him so firmly he couldn't drop his hip down in fear of it being ripped off before he gave a groan and suddenly he came into her again with another thick dollop as he groaned and fell back once more.

"Aaah... that was good... but I'm gonna need a little more time to cool off before we can do a little more... how about a movie?" Isaac groaned gently, slumping back as he managed to lift his paw up and clapped her backside as she gave a chuckle. But just as he grinned at her in amusement, Isabelle stood herself up, clapping a paw to her backside to keep the mess in before musing she was going to shower. Isaac watched her go in amusement before he sighed gently and then he sat himself up and noticed some cleansing wipes stuffed under the sofa as she sat herself up. He grasped it, yanking them out and then firmly wiping himself tenderly before he then crunched it up and threw it into the nearby rubbish bin.

Isaac then pulled himself up on off the floor, he then turned on the television and flicked through to the cheap movie channels and then slumped onto the sofa, legs spread and just wheezing in relief as he slumped back into the sofa. He found something boring to flick on and then he settled back to have a nap for a little while, sighing in relief and satisfaction, but knowing ever well he was still feeling very horny. Then, with a soft groan, Isaac was woken up as his sister passed him a cold drink from the fridge and then slumped on the sofa with a pleasant smile.

"So... what have you got in mind for the rest of our weekend?" Isabelle teased as she settled down rather calmly, upon the sofa with him looking towards the movie. Isaac took in the drink from the beer can with a sudden snort of amusement as Isabelle copied him then wheezed and patted on her chubby stomach. She then rolled flat onto her back, grinning up at her brother as Isaac then gave a groan and slumped back down beside her, both of them naked and seemingly content as she gave a chuckle. "Sheesh... I'm not going to have an ass left by Monday, am I?"

"Heh... my dick might get a sprain..." Isaac stuck out his tongue at his sister as she gave a snort but they just slumped back onto the sofa and let the movie continue on with some pointless plot. They both slipped into a light daze, if not for them being utterly naked as they slept away, they might have looked as adorable as any siblings. Sometimes they both pondered if the other one was ever going to talk about this time with regret, but the truth was they were just getting rid of awkward lust and being careful not to hurt one another... just scratching each other's back. But as they continued to lounge, Isabelle sat up suddenly and gave her brother a gentle tweak on the ear as he gave a grunt and eyed her cautiously. "What is it?"

"How about I put on a pair of the mongoose's knickers, we fuck in her bedroom then stuff the knickers somewhere awkward for her to find at a later point?" That was a little spiteful from Isabelle, but when she grabbed the pair of tight little polka dot panties that would really ride up between Isabelle's plump cheeks, the sudden possibilities glittered in Isaac's mind as his cock pinched and he licked his lips.

"I'm game..."

The End
