Unforeseen Consequences

Panting softly as she clambered up the stairs, Nia held her belly with a slight frown, thankful that her family already thought of her as somewhat of a tomboy, which meant that she could easily wear baggy hoodies all day long without anyone batting an eye. The young rabbit hopped up the last few remaining steps, out of breath as she pulled herself up, her entire body giving a startled jerk as she spotted her mom stepping out of the bathroom with a laundry basket in hand. Wanting to hide her condition, the teen quickly straightened up her back and put on a fake smile, holding her breath and hoping that her face wasn't too red as the other bunny walked past her, giving her head a quick pat, 
“Hey, sweetie! How was school?”
“Oh, it was… fine. Just gotta go take a leak real quick!”
As soon as her mother was out of sight, Nia let out a loud gasp, huffing and puffing as she quickly slipped into the bathroom, closing and locking the door behind her, wanting no one to see what she was up to. Alone and with some privacy finally, the girl pulled her hoodie off, revealing her bulging belly, staring at it in the mirror with a shameful grimace as she gently laid a hand on it, giving a sigh. It had been a few months since she'd fooled around with her twin brother and her best friend, having thought nothing of it at the time, at least not until she began feeling off. The rabbit wasn't too worried until she started noticing her belly starting to balloon up, slowly but surely. She'd hoped that it had just been the colder winter seasons causing her to stay inside and indulge in a few more snacks than usual, but eventually she couldn't just pretend that nothing was going on. Reaching into her back pocket, Nia pulled out the small package she'd gotten from the school nurse that day, opening it up and biting her lip as she stared at the pregnancy tester in her hand, groaning as she pulled her sweatpants and her panties down before sitting down on the toilet. Having to relax and calm down for a second before she got a stream going, the cub carefully stuck the tester between her thighs, setting it aside as she finished up and cleaned herself off, pulling her pants back on before finally looking at it. The bunny wasn't particularly surprised by the little plus sign visible on the testing stick, though she was still rather shaken by it, flopping back down on the toilet seat as her ears wilted down, sighing as she leaned her head back, 
“Guess I gotta tell Jacob…”

Jacob was lounging in his room, laying back on his bed as he idly fiddled with his ear, thumbing through his biology book, trying to decide whether to get his homework out of the way now or whether to just enjoy the weekend. He wasn't sure where his twin sister had gone off to, as she didn't walk home with him like usual, simply slipping away towards the nurse's office while giving some excuse about a sore throat. Nia quickly returned to the boy's mind as he turned the page on his biology schoolbook only to be met with a two page spread showing the female anatomy, in some rather graphic detail as well. The rabbit bit his lip as his eyes focused on a drawing of a spread out slit, arrows pointing out each part of it, his pants starting to tent as he eyed up the clit. He hadn't blown a load in almost a week, his own hand feeling rather disappointing after getting to experience not just his twin sibling but also her best friend as they fooled around with him. The group hadn't repeated what happened that afternoon, or even talked about it afterwards, a slight sense of awkwardness lingering around the trio, especially Jacob and his sister, as if they all desperately wanted to do it again but none of them quite knew how to ask the others for it. 

Feeling his cock starting to poke out of his sheath, rubbing up against the inside of his underwear as he squirmed around on his bed, the boy debated whether he had enough privacy to go for a quickie, listening to his mother humming as she wandered about in the hallway outside of his bedroom. Just as the teen was about to pull down his pants and get to work, he heard footsteps approaching the door, immediately yanking a blanket over his crotch to hide the bulge as he set down his book. To Jacob's relief, the incoming visitor wasn't his mom or dad, but his twin sister instead, Nia peeking into the room with a slightly sheepish look on her face, 
“Hey, got a minute?”
Not knowing his usually brash and bold sibling to be quite so meek, Jacob immediately nodded and sat up, thinking that something must be seriously wrong to get Nia feeling so shy. He still kept a blanket over his crotch though, thinking it'd be for the best to hide his excitement down there, a small blush on his face as he beckoned the girl to sit down next to him on the bed. Nia plopped her rump down next to her brother with a small huff, just staying silent for almost a minute as she tried to figure out how exactly to tell her twin that she was pregnant with his child, finally simply pulling off her hoodie and shirt, and showing her bare belly to the boy. Jacob stared at the obviously pregnant girl for a moment, his mouth hanging open, before he finally gave a small cough, pointing at her belly, 
“Is that… from… what we did?”
Nia nodded with a sigh, looking up at her brother with a small, yet worried, smile. Unsure of what to do, how to confront the girl, Jacob simply hugged his sister, wrapping his arms around her in a tight embrace as she did the same, their cheeks rubbing together as they nuzzled. 

As the twins hugged, Jacob couldn't help but to feel his urges flaring up once more, with the girl's arms wrapped around his back, her chin resting on his shoulder as she let out tiny, almost imperceptible moans, her big belly rubbing up against him. Clutching her brother, Nia was glad for the comfort, feeling slightly more at ease as her nerves calmed down, thankful that the boy wasn't freaking out about her being knocked up by him. It didn't take long for her to notice just how happy her twin was however, suddenly feeling a hard bump rubbing up against her thigh, breaking off the long hug and yanking the blanket off of Jacob's crotch, smirking as she saw the erection poking against the heavily blushing cub's pants, 
“Wow, you're taking the news really well~”
Chuckling awkwardly as he rubbed his neck, Jacob was about to quickly explain the situation between his legs, how he'd already been all excited before she'd even stepped into the room, though he couldn't quite get the first word out of his open maw before the girl lunged forwards to press her lips against his. With a surprised, yet very pleased, moan, the boy happily accepted his sister's tongue into his maw, wrapping his arms back around her as they kissed, making out with the same passion they'd ignited the first time they fooled around together some months back. Feeling her loins burning with the sort of heat she hadn't felt since taking her brother's cock inside of her, Nia let out a small whimper as the boy's tongue swirled around inside of her muzzle, wet slurps and smacks filling the little bedroom. Reaching a hand down between her twin's legs, the girl felt up Jacob's stiff manhood, rubbing the palm of her hand against the front of his pants, making him squirm and twitch as she felt his girth throbbing right under his clothes, both bunnies soaking their underwear together. Praying that their mother wasn't outside of the room, unsure of exactly how obvious their passionate makeout session was to anyone who might've been listening in, Jacob pressed a few fingers against his sister's crotch, feeling like he was in heaven as she began rocking her hips back and forth, humping her sopping wet slit against his hand. 

Pushing up against one another, panting and moaning as they both shivered, the twins masturbated one another over their clothes, groping each other like a pair of lovesick teens hiding out from their parents. Though they were related, the taboo didn't hinder their lusty moment in the least, possibly even only making it that much more thrilling as the rabbits humped and made out. With how pent up the siblings both were, neither was satisfied with just a little over the pants fondling, they needed each other's bodies. Gently pushing the girl over onto his bed, Jacob broke off their kiss, wiping his wet lips on his sister's chest as he helped finish off the undressing that she'd already started, taking off her pants and slipping her panties down as she laid back with a needy smile. Returning the favour, Nia stripped her brother bare as well, eyeing up his twitching dick as she rolled him onto his back, crawling on top of him, giving him one final kiss on the muzzle before turning around, shoving her face into his crotch instead. Parting her lips, the girl took Jacob's pulsing girth into her mouth like she was starving, swallowing him all the way down to his sack as the boy gripped his plump ass, moaning against her fur while gently bucking up further into her muzzle, already on the verge of exploding just from the feel of her tongue caressing his manhood. Midway through his moaning, Jacob felt a few drops of something dripping onto his snout, looking up to see his twin's soaked mound hovering over his face, gently swaying from side to side as the girl bobbed her head on his cock, just waiting for a little oral action. More than happy to oblige, the boy grabbed his sister's cotton ball tail, gently lowering her crotch down onto his muzzle as he wrapped his other arm around her thigh, slipping his tongue between the warm and inviting pussy lips, finally getting a taste of her again. Nia moaned against the cock throbbing in her mouth as the cub's tongue spread open her slit, rubbing at her clit in little circles before diving deep into her cunt, making every muscle in her body clench up as the waves of overwhelming pleasure rolled over her, making her forget about anything else in the world, focused only on the feel of her brother's tongue in her pussy and his cock in her maw. 

Getting closer and closer to popping her top, moaning wildly with the boy's cock stuffed down her throat as she ground her hips against his face, Nia was just seconds away from cumming when she suddenly lifted up her rear off of her brother's muzzle. With his entire snout smeared with the girl's juices, and her slit thoroughly slathered in his spit, Jacob gasped for air as he glanced over at his twin, hissing softly as she slid the girth out of her maw, unsure of why she'd stopped their fun when they were both so close to finishing. Though Nia certainly wanted, and was planning to, get off with the help of her twin, she didn't want to waste the opportunity on just cumming on his tongue, not when she could instead be fulfilling one of her fantasies, something that had been plaguing her mind ever since the two first got together. Panting and holding her belly, the bunny turned around and crawled next to her sibling, laying down and cuddling against his side as she smirked, wrapping a hand around his cock and slowly stroking it, using her own saliva as the lube, 
“You know, there's one thing I really wanted to try with you~”
Shivering softly as the girl's hand massaged his rock hard shaft, edging him while he panted, Jacob grinned, 
“Oh really~?”
“I'm… well, I'm really into… anal stuff. You know, playing with my tailhole and all that…”
The boy snickered quietly, 
“And you want my help with that~?”
Nia nodded, feeling the cub's cock throbbing against the palm of her hand, taking it as a very good sign as to whether her twin brother would be willing to fulfil yet another one of her kinky fantasies, 
“I think I could do that~”

Dipping a finger into his maw, licking and slurping at it as his twin watched with a smirk, Jacob slathered his finger with spit before pulling it out, reaching his hand behind the girl. Clinging to her brother, Nia's eyes closed in bliss as she felt him spreading her ass cheeks open, his wet finger pressing right up against her tight tailhole, rubbing up against it as she let out a tiny moan, biting her lip. With only a little effort, Jacob was able to push his finger inside, slowly sliding it down further into his sibling's pucker as she whimpered quietly, nuzzling her face under his chin as she began to wriggle and squirm around, her legs opening up and her soaked slit pressing against him as she began to hump his thigh like a feral dog in heat. The boy could tell that she'd toyed with her asshole before, easily stretching out over his finger as he pushed deeper, quickly managing to hilt his digit into the cub's hole as the pucker twitched and squeezed down around his finger. Jacob was fairly certain his sister didn't have any actual sex toys of her own, leaving him to ponder what she'd used to play with her tailhole, his dick twitching as he imagined the little rabbit laying down on the bathroom floor in ecstasy as she tried to hold in her moans while using a toothbrush to train her asshole, or maybe even borrowing their mother's toys for a while. In bliss as she shoved her rear back against her brother's finger, Nia was close to cumming once again, when both rabbits perked up at the sounds of approaching footsteps, the boy quickly tugging his blanket over them both. The door opened as their mother walked in, a basket of freshly cleaned clothes in hand, seeing the two cubs snuggling together on Jacob's bed, unaware of the lewdness that was happening just under the covers, 
“Aww, look at you two, you're so sweet together~”
Praying that her mom wouldn't notice her brother was fingering her tailhole, Nia just went along with it, smiling and trying not to look too worked up as their mother turned around to put the clothes into the boy's closet. Though Nia seemed intent on just acting innocent until they had their privacy again, Jacob had a very different idea in mind, horny enough that he was only further excited by their mom walking in. With a sly smile, he added another finger into his twin's pucker without any warning, getting a tiny squeak from Nia as she went bright red, quickly disguising her pleasured outburst as a cough as their mother glanced in their direction, quickly cuddling close against her brother and tucking her snout under his chin as she shivered and strained not to moan, silently whimpering just inches from a climax as she tried to subtly grind against the boy. 

Completely blind to what was happening just behind her back, the twin bunnies’ mother hummed as she diligently stacked up her son's closet, before finally turning back to head out of the room, gently closing the door behind her as she smiled at the cuddly pair. As soon as the woman was out of the door, Nia tossed the blanket off of them both, sliding her brother's fingers out of her ass and crawling onto all fours, her flank pointed right at the boy as she panted with a lusty growl, her twitching and gently gaped tailhole glistening with saliva, 
“Mount me, right now~!”
Not needing to be told twice, the boy jumped up to his knees behind his twin, his cock as hard as diamonds as he slipped the tip under her tail, grabbing her by the hips as he bucked forwards. Sliding into the girl's snug hole, Jacob immediately doubled over, laying down against her back as he gave a grunt, gritting his teeth as he felt his sister's tailhole gripping every last inch of his shaft. Nia was equally as delighted, her eyes almost crossing from pure pleasure as the boy's girth pushed into her pucker, stretching her wider than her previous toys had managed to, instantly getting her slit wetter than ever before, leaking enough to form a wet spot on the bedding between her legs. Struggling to hold back their moans so as not to alert their parents, the cubs played right into the stereotypes about rabbits, rutting like their lives depended on it, panting and whimpering as Jacob ploughed into his twin's tailhole, his hips slapping against her ass as he hugged the girl from behind, groping at her chest, belly, and pussy while hammering at her asshole. Already on a hair trigger, neither bunny could go on for very long, Jacob's sack twitching and pulling up taut as Nia's hole milked him like she'd been made just for his cock, his eyes squeezing shut as he exploded deep inside of the needy cub. Feeling her brother's load spraying into her tailhole, Nia squeaked while covering her mouth as she came right along with him, squirting on the bedsheets as her pucker clenched tight around the base of the boy's length. 

Laying face first on the bed, drooling as she moaned deliriously, Nia's legs kicked the air as her twin pulled out of her tailhole, cum gushing down her ass cheeks and thighs as she panted, the boy leaning against her just to stay upright. Neither rabbit was quite satisfied yet though, pent up enough that they both had another round left in them still, and she knew it. Without warning, Nia turned around and jumped on her winded twin, pinning him down under her as she rose up to her knees, grabbing onto his cum-glazed cock as she spread her slit with her other hand, shoving him into her waiting cunt as both siblings gasped. Though he was stuck under his sister, with little hope of getting out from under her, there was nowhere that Jacob would've preferred to be instead, laying back and basking in the heavenly feel of the girl's tight pussy, every curve and squeeze making him shiver as she rode his cock. The boy reached up to caress his twin's body, one hand rubbing her belly as another gave her chest a grope, his fingers softly squeezing her tits, having grown noticeably since she'd gotten knocked up. In ecstasy, every grope and fondle making her entire body light up like a bonfire, Nia barely even noticed as a few squirts of her milk dribbled out from her breasts as her brother massaged her chest, dripping onto Jacob, a few even landing on his face as he moaned. Thrusting up against his sister's cunt as she jumped up and down on his girth, Jacob could barely breathe, wheezing as his toes curled and his leaking cock pulsed balls deep in her mound. Coming down on the boy one last time, taking every last inch of him inside of her as she squeaked, Nia came for a second time, as did her twin. Holding hands as they both climaxed, Jacob shivered as his ropes of cum were swallowed up by the girl's snug slit, oozing down onto his crotch as he pumped more and more deep into the moaning cub's pussy, surprised at just how much seed he still had left even after unloading so much of it into her tailhole. Nia collapsed down on top of her brother, the siblings still locked together as she looked up at him, panting hard. Jacob simply smirked before wiping up some of her milk she'd sprayed onto his face, licking it off of his fingers before giving her a kiss, letting her get a taste of her own milk as well. 

The twins stood in front of their parents, a shocked look on the father's face while the mother almost seemed amused, Jacob's hand on his sister's bulging belly as both siblings smiled with a shy blush, 
“...and yeah, that's… well, that's kinda how I got her pregnant.”
With her hands behind her back, almost purring as her brother gently stroked her belly, feeling the little bunny inside kicking softly, Nia jumped in to finish the story, 
“It's about a month until I'm supposed to give birth. We don't… we haven't figured out whether it's a girl or a boy yet~”
The bunnies stood side by side, like a perfect teenage couple as they snuggled close to one another, rubbing their cheeks together as their parents watched on, the dad too stunned to say a word while their mom giggled, 
“Guess we're going to need a nursery.”
