Sibling Teasing

Shifting around from one leg to the other, clutching the backpack hanging off of his shoulder as his whiskers twitched, his long and sinewy tail nervously wrapping itself around his ankles, Tommy stared at his home from the end of the driveway, lingering around outside as he sighed, glancing at the windows while feeling a bead of sweat on his brow. The chubby opossum still lived with his mom even though he'd just turned 21 a few weeks ago, but that wasn't what made the boy so nervous, instead it was that so did his older sister. Even though Megan was only a couple of years older than him, the girl had made teasing and tormenting her younger brother into an art form, perfecting her skills and knowing just what buttons to press to cause Tommy to go through as much anguish and awkwardness as possible. Spotting that their mother's car wasn't on the driveway only made him that much more anxious, knowing that Megan could go all out on her teasing with no fear of their mom discovering what was going on, though the woman being there usually didn't get his big sis to be much kinder to him anyway. The chubby boy's sibling knew that he didn't have much luck with ladies, and though he tried his best to behave, he'd lose all sense of control whenever he got worked up, something that the older opossum was more than happy to take advantage of to amuse and pleasure herself. Tommy knew how wrong it was to give in to the temptations that his sister would offer up to tease him, and always regretted it after it had happened, but time and time again he would lose control and surrender himself to his raging lust. Absolutely certain that the girl was just waiting for him inside, ready to pounce on him and lead him down some dark path yet again, Tommy sighed and began to slowly walk towards the front door. He momentarily debated just going over to a friend's place for a while, hoping to dodge his older sister's teasing for a bit longer, but he knew that he had to come back home sooner or later anyway, resigning himself to whatever she had planned out for him. Pulling out his keys and grabbing the door handle, the boy let out a nervous sigh as he gave it a twist, stepping inside. 

Walking deeper into the house after kicking off his shoes and hanging up his coat, Tommy was quickly met by the family dog, Bella, running up to greet him, the large German shepherd pushing her snout against him and wagging her tail as she panted, getting a chuckle from the boy, 
"Hey, don't knock me over now, good girl~" 
Petting the dog, Tommy kept his eyes up, nervously scanning the living room for any signs of his sister, thankful to find no hair nor hide of the older opossum. Stepping over Bella, letting the feral girl run off to continue her nap in her bed, the boy took his backpack and headed up the stairs, hearing that the television in his room was on, spotting the door ajar as soon as he hopped up the final step, feeling his heart pounding as he neared the doorway, knowing full well that his sibling was waiting within. Stepping into his room, Tommy found Megan sitting on his bed, smirking while idly playing with her long tail, not even looking over at the boy, 
"Hey, Tommy~" 
The girl was slightly taller than her little brother, and a fair bit slimmer than him, her blonde hair coming down to her shoulders, sporting a slightly lighter tone of grey fur than Tommy. Knowing her brother's tastes all too well, the girl was wearing a black skirt and top, leaving a good bit of her thighs bare, long black socks coming up to her ankles. Pretending like she didn't see the other opossum staring and drooling at the doorway, Megan leaned back with a slight mischievous smirk, swaying her legs as she subtly hiked her skirt up a few inches, letting her brother peek at more of her thigh as she gave a soft sigh. 

Unable to take his gaze off of the eye candy sitting on his bed, Tommy grimaced and blushed, groaning to himself as he felt his lower half quickly waking up, feeling a tightness in his shorts while trying to tell himself to look away, aware that the young woman dressing exactly like how he liked his girls was anything but a coincidence. Managing to pry his eyes off of his sister for just long enough to drop his backpack off, the boy tried to resist the urge as he felt his cock pushing further out of his sheath, his wet tip already rubbing up against the front of his underwear as he desperately tried to think of anything except his sibling, but the only thing he could think of was her perfectly plump thighs and her wonderful tits. With his back turned to Megan in a vain attempt to hide his excitement, mouth watering and his dick standing up stiff while he tried to get his mind off of her, Tommy was right on the verge of just storming out of his own bedroom for a long, cold shower when the girl suddenly grabbed the tip of his tail, making him jump slightly as he turned to look, seeing her smirking up at him as she patted a spot on the bed next to her, 
"C'mon, sit down and watch this movie with me~" 
The boy quickly looked down at his feet, fiddling with his hands while trying to subtly pull his shirt down to cover his erection, failing miserably, 
"I… I think I'm gonna head t… to the sh… shower first…" 
Megan didn't bother to hide her grin as she leaned in, her arms pushing her tits together as she spread her knees, giving her little brother a tiny flash of her white panties under her skirt, 
"Aww, really~?" 
Feeling his control slipping, Tommy gulped as he took a tentative step towards his sibling, sitting down next to her while his breath quivered, 
"I… I dunno… maybe I could w… watch some stuff with you… just for a bit, before that s… shower…" 

Taking a seat next to his sister, shivering as she immediately pressed her side against his, Tommy tried to stay as calm as he could while constantly adjusting his shirt and pants to hide his erection, sweating and squirming as he noticed the girl peeking at him every now and then, a devilish smirk on her muzzle. Though he hopelessly attempts to keep his eyes on the TV, the younger opossum couldn't help but to let his gaze stray towards his sibling every now and then, eyeing up her wonderful legs from the corner of his vision, slowly turning his head to take in the rest of her alluring body, running his eyes up her thighs and over to her chest as he held his breath, leaking precum into his underwear like a running faucet. Megan was more than happy to let the boy ogle at her all he wanted, but she wanted to take her teasing up another notch as well, not content with just keeping him on the edge by forcing him to watch from the sidelines. Without warning, the girl stood up and shifted spots to sit in her brother's lap, laying her flank down right over his fully erect manhood as he gave a surprised yelp, trying to half-heartedly push her off of him but instead mostly just accidentally groping at her ass as he whimpered, 
"H… hey, what are you doing?!" 
"What? Can't a sis just sit in her little bro's lap~? We used to do this all the time when we were younger, and you loved it back then as well, right~?" 
Groaning, Tommy propped himself against the squeaking bed as his sister made herself comfortable on his lap, shifting her rump around from side to side to find a good position, feeling his rock hard shaft throbbing as it pressed right between her ass cheeks, getting a soft giggle out of her as she fanned at her face, 
"Woof, is it just me or is it getting a li'l bit sweaty in here~?" 
Pretending to get too heated for her outfit, Megan grabbed the hem of her skirt and hiked it up a little, giving her brother a perfect view of her ass squeezed into her tight panties, her buns squeezing his shaft between them as the big bulge pressed against the front of his shorts. The situation quickly took a turn for the worse as the boy felt Megan slowly rocking her flank back and forth, jerking him off as she still acted like nothing was out of the ordinary, leaving him gasping and panting while clinging onto the final shreds of his self control, trying desperately not to just give in to his sister's temptation as she practically rode his cock. 

It didn't take long for Tommy to lose what little control over himself he still had, giving in to his feral side as he began to dry hump his sister without holding back, grabbing her from behind as he thrust against her rump while grunting, pumping pre into his underwear while practically fucking the older opossum, only a few layers of clothes keeping his cock away from the girl's snug holes. Panting softly as her brother humped her from behind, shuffling back slightly and shifting her posture so that the boy's rock hard erection was grinding against her mound instead of just her ass crack, Megan closed her eyes with a devious smile as she listened to her younger sibling whimpering. Grabbing the bigger opossum by her waist and bucking up into her with a moan, Tommy couldn't think straight, his mind utterly clouded with lust as he bounced his sister up and down on his lap, trembling every time she let out a dainty moan, his face buried into the back of her neck, sniffing and huffing as he dreamed of getting to slide his cock into her slit, so close yet so far away. The temptation was only made that much worse when Megan grabbed one of the boy's hands, shifting it off of her hip and guiding it down the front of her panties instead, pressing his fingers against her soaking wet pussy as she moaned, his dick grinding against her slit through his shorts while he simultaneously pushed a finger inside of her. Feeling the girl's tight cunt clenching down around his fingers as he pushed deeper inside of her, her juices drenching both her underwear and her fur as she gasped, Tommy could hardly believe what as happening to him as his sister reached back over her shoulder, caressing his cheek while cooing, 
"Oh, you're such a sick little boy~! You're a real pervert~!" 
Grimacing and whining as he inched closer and closer to the edge, Tommy was absolutely sure he'd blow a huge load in his pants while knuckle deep in his big sister's pussy, right on the verge of cumming when she suddenly stood up without saying a word, his fingers slipping out of her mound as she pulled her skirt down and walked off to the door. Megan was grinning as she glanced back at the utterly desperate boy, a look on his face as if he was starving and she was dangling a piece of steak right in front of him, 
"I don't think I should be hanging around with someone so sick and perverted, who knows what you'll do to me~" 

With a horrified look on his muzzle, Tommy watched his older sister marching out of his room, slamming the door behind her as she struggled to hold in her laughter, amused at the torment she was putting her little brother through. Feeling the climax he'd been utterly desperate to reach slipping through his fingers, the boy groaned and quickly dropped down to his knees on the floor, ripping his shorts open and yanking his underwear down in a fit of lust, panting in a frenzy as he gripped his cock with both hands, pumping at it like his life depended on getting rid of the blue balls his sibling had left him with. His own hands certainly weren't as good as the dry humping he'd been treated to, or maybe even Megan's pussy, but he needed to empty his sack right then and there, his fingers slipping on his slippery shaft as he smeared precum along the entire length, whimpering and moaning while thrusting against his hands, spraying a wet spot of pre onto the carpet. Though the boy thought that his sister had left entirely, Megan was instead still waiting just on the other side of the bedroom door, smirking with an ear pressed against it as she listened to the needy gasping and grunting coming from within, a hand stuck down the front of her panties to rub at her clit and to finger her sopping wet slit. Both siblings masturbated to the thought of each other, Tommy humping the air in desperation while his sister plunged another finger between her pussy lips to the sound of the boy furiously stroking himself, only a few steps away from one another. Megan enjoyed the sounds of the chubby opossum's desperation for a few minutes before finally turning to leave, not wanting her little brother to get off before she'd enacted the final step of her plan, not content with just teasing him with a horrible case of the blue balls. 

Unaware of what was happening just outside of his bedroom door, still trying to imagine his big sister sitting on his lap with her dripping wet pussy grinding and rubbing up against his cock, Tommy continued furiously jerking off, pumping at the entire length of his shaft while kneeling on the floor, whimpering in a drooling mess as he crept towards an orgasm once more. Getting within a hair of climaxing again after he'd been interrupted the first time, the boy suddenly heard his bedroom door opening up again, freezing in place with a hand squeezing the base of his girth as he turned to look, a lust-crazed glare in his eyes as the door swung open. Cracking the door just enough to fit the feral canine in, Megan shoved Bella into her little brother's room with her foot, having to nudge the four-legged lady inside against her will as she whimpered and tried to push back against being forced into the bedroom, her tail quickly dipping down between her back legs as her eyes met the lecherous opossum's, 
"Since you're so sick, you ought to spend more time with Bella than me, you animal~" 
Megan quickly slammed the door back closed again as she pressed her ear against it, shivering in excitement as she fingered herself, her legs quivering slightly as she listened to the pup giving a nervous whine, hearing her brother whispering to the feral, 
"F…fuck… I… I'm sorry, Bella, I promise I'll be fast this time around…" 
Tommy knew that it was a lie, gasping as he immediately shot up and cornered the German shepherd, staring down at her with his cock in hand as the scared dog curled up against the door, already knowing what was in store for her. He heard his sister loudly masturbating just on the other side of the door, moaning and howling as her fingers hammered in and out of her cunt, big droplets of her sap trickling to the floor as she listened to her brother snatching their dog, Bella's scared whimpers making her tail twitch as she tried not to cum too early. 

Tommy grabbed onto the dog's collar, giving it a yank to force Bella up onto her feet while he knelt down in front of her, slapping her snout with his dripping and twitching manhood, still pumping at his cock as the canine flinched at his cock getting shoved in her face. The feral girl had gone through the treatment enough times to already be trying to squirm free of the boy's grasp as he grabbed onto her muzzle, his pre-soaked fingers pushing past her lips and prying her mouth wide open, her tongue hanging down the side of her maw as she whimpered, desperately trying to backpedal away from the grunting young man, her feet helplessly scrambling on the slippery hardwood floor. Tommy pushed his tip up to the open muzzle and laid his cock down on the Germans shepherd's tongue, holding her muzzle open with both hands as he huffed and trembled from his head to his tail, desperate to sink his dick inside of something wet and warm, not caring much about whether that something was his older sister or the family dog, or if that something was even very willing to let him fuck it. With a loud groan, the opossum bucked his hips forwards, driving his girth deep down the back of Bella's throat, dipping his cock all the way down to the base and making her throat bulge as he shoved every last inch of his shaft he could fit into the writhing dog. Bella immediately gagged hard, her claws scratching at the floor as she desperately tried to get away, her whimpers and whines almost entirely disappearing under the sounds of her throat being fucked by the desperate boy, wheezing as she tried to gasp for air in between the opossum plunging in and out of her muzzle. Biting her lip and listening close, Megan could make out the telltale sounds of her little brother's manhood gliding down their dog's throat, her entire face red from the heavy workout she was getting as she moaned, one hand fingering her own dripping pussy while the other slipped underneath her top to fondle at her tits, her eyes closed as she focused on the gagging sounds of the feral pooch getting throatfucked. Bella jerked around, trying to pull her muzzle off of the cock buried down her maw, barely able to get a single breath of air as the boy ruthlessly pounded at her mouth, her saliva running down his shaft and sack as he grunted like a wild hog rutting a sow in heat. 

After a few minutes of fucking the dog's muzzle, with his dick well lubed with her drool, Tommy finally let go of her snout, the German shepherd immediately lurching back and pulling off of his girth with one final intense gag as her entire body spasmed, leaving her gasping for air as she tried to sluggishly crawl away from the boy. Tommy wasn't done with her yet however, far from it, having just gotten himself lubed up and ready to take the feral's other holes, grabbing the base of her tail and roughly yanking her back as she gave a yelp. With the canine's spade and tailhole both just staring him in the face, the opossum blindly thrust against her rear, his tip pressing against her asshole as he continued pushing, not even sure which hole he was taking as he felt the squealing girl stretching around his well lubed girth. Though the agonised whimpering would've made Tommy feel awful at any other time, he couldn't get enough of it while in the midst of his lustful frenzy, only getting more worked up by the sounds of her yipping and the feel of her holes squeezing around him hard as she tried crawling away from him. He hated just how horny it all made him, but the opossum couldn't deny the pleasure, slamming his cock balls deep in Bella's tailhole as he growled and foamed at the mouth, another sharp bark coming from the Germans shepherd as his free hand felt around between her back legs for a moment. The boy quickly found the feral's spade, shoving three fingers knuckle deep inside of her cunt while he hammered at her asshole, fucking her soft cookie with his digits at the same time as her tailhole milked him hard. Yanking her back by the tail whenever she tried to scramble away from under him, Tommy raped the struggling dog as she howled in pain, her every yelp getting another pleasured moan from his sister just on the other side of the door. 

Ramming into the German shepherd's asshole as hard as he could, lifting her back legs into the air at the apex of every thrust as Bella continued whimpering, feeling both of her holes squeezing around his fingers and dick as he quickly approached a point of no return, Tommy had long forgotten all about any notions of mercy or guilt, the only thought in his head being that of emptying his balls. The boy's older sister had a very similar frame of mind, grinding her hand against her pussy as she wailed nearly as loudly as the dog being raped right next to her, loving how rough her brother was being with the bitch as her juices ran down her thighs like a waterfall. Unable to hold back for a second longer, Tommy punched his girth all the way down to the hilt inside of the canine, Bella's entire body jolting in a series of rapid fire yips and barks as the boy came inside of her, a torrent of hot seed rushing into her asshole and spurting out her pucker as the opossum roared, pumping out a huge load after being edged and teased for so long. Hearing her sibling climaxing inside of the whimpering dog, Megan came as well, screaming into her hand as she squirted down her legs, soaking both her skirt and her panties as a pool of her juices collected beneath her feet, only barely able to stay upright as she leaned her back against the door. Gasping, Tommy pulled out of the family dog, feeling an immediate twinge of guilt as Bella limped away from him, cum gushing out the German shepherd's gaped open tailhole as his sister opened the door, letting the feral slip out of the bedroom and scamper off to hide somewhere. Panting, Megan glanced at the boy still on his knees, a shocked look on his face as what he'd just done sunk into his head, his rock hard dick twitching in the air and spraying a few final ropes of cum as the girl licked her sticky fingers clean with a smirk, giggling while the ashamed opossum stared down at the floor, 
"Eww, you're such a huge pervert~!"
