Teaching the Basics

Matt frantically ran from room to room as he hunted down every last thing he had filed on his mental list, desperately trying to zip up his jeans while searching for his notebook, his backpack slung from one shoulder on his back. Mary grinned as she sat up on the sofa, cloaked in a purple silk morning robe, her pregnant belly peeking out from the open gown, her crotch still slightly moist and a few white drops drooling out onto her tailhole from her early morning session with her son. She grabbed a notebook from the coffee table and held it up, the front of it full of miscellaneous scribbles and drawings, the pages slightly warped from heavy use, 
"This what you're looking for, darling?" 
He sighed and jogged over, snatching the notebook and stuffing it into his backpack before leaning down and giving the vixen a kiss on her cheek, 
"Oh, thank you so, so much! I'm gonna need to run or I'm gonna be late. I swear, I really need to learn how to say no to you, or I need to set my alarm so I have an extra half an hour just to breed you every morning." 
Mary giggled and gently pet her puffed up belly, 
"If you ask nicely, I can write your teachers a note to explain why you're late to your classes~" 
Both of the canines laughed for a moment as Matt slipped on his shoes and opened up the front door, waving goodbye to his mom, 
"Alright, I'm going, you and the kids have fun!" 
"Bye sweetie, you have fun as well! And drive safe!" 
He quickly dashed to his car, throwing his backpack onto the passenger side seat before cranking on the car, panting slightly as he began his drive towards his school. The distance wasn't particularly large, but he had always had a nasty habit of underestimating the time he'd need to get from one place to another, that issue only exacerbated by the irresistible offers made by his pervert of a mother, and more recently his sister as well. 

Matt pulled into the parking lot of the school building and grabbed his backpack, hurrying towards the front door, the lack of any other students milling about outside making him worried that he might be very badly late. He ran to his class and pulled open the door, thankfully finding that the rest of the students were just settling down, his arrival only a minute or two late. The teacher, Miss Elena, smiled at the panting young man, thumbing through a stack of papers as she spoke, 
"Ah, just in time as always Matt, good on you for keeping us all on our toes. Keep this up and we'll soon have a betting pool on if you'll make it here on time or not."
He laughed quietly and sheepishly muttered an apology as he sat down on the only seat still available, at the front of the class off to the side. He pulled out his stack of books and papers, opening up a folder to make sure that his project was still there, letting out a sigh of relief that it was. The project was already several days late, but thankfully Elena had been kind enough to give him some extra time. Getting to school in a timely manner wasn't the only issue for the fox, needing to take care of several children and needy partners also meant that staying on top of his schoolwork was an issue. As he settled down and caught his breath, the teacher cleared her throat and began the class, welcoming all of the students and slowly walking back and forth as she talked about the subject matter of the day. Elena was a Fennec fox, in her mid thirties, her fur a sandy tan colour. She was just a tad shorter than Matt, owing to the particularly short stature of her species. Her large ears flicked around as she enthusiastically, occasionally sitting on her desk for a few moments before jumping down and writing on the chalkboard. Though he tried to keep his focus on his notes, Matt found his mind starting to wonder more and more, his stare straying away from the equations and instead creeping over to the teacher's body. She had on a tight v-neck sweater and a skirt, the outfit leaving quite little to the imagination when it came to her figure. Soon enough, the boy had to stealthily cross his legs just to make sure she or his classmates wouldn't notice the very obvious boner jutting up in his jeans, his cheeks slightly blushing as he tried to act nonchalant, his hands scribbling nonsense on the paper just to make it seem like he was doing what he was supposed to instead of creeping on his teacher. 

Matt suffered through the whole class, his gaze rotating between the Fennec's sensational behind, his notebook, and the clock on the wall, the hands on the clock seemingly crawling along at a snail's pace. Finally, the bell rang, all the other students quickly hopping up off of their seats to enjoy the brief moment of respite before needing to get to their next class. Matt took a second to breathe and steady himself, slowly packing up his stuff, hoping that his erection might go down a little before he stood up. He didn't have any classes in the next slot, giving him about an hour and a half of free time, meaning he wasn't in a huge hurry. He picked up his written project and approached his teacher, the rest of the students having already left the classroom, leaving the two totally alone. He and the Fennec fox were already quite friendly with each other, the boy having known her for multiple years, though his horniness made him feel slightly more awkward talking to her on that day, 
"Uhh… Miss Elena? Here's the paper I was late on." 
"Ahh, great! Give it here, I can take a quick peek at it, just see that it has all the required parts." 
The Fennec grabbed the stack of papers and began flipping through them, leaning on her desk with one leg on the ground and the other up on the desktop, accidentally giving Matt a brief flash of her deep red panties under her skirt. He felt his cheeks beginning to glow once more, a drop of sweat rolling down his face as he fixed his gaze onto the windows outside, trying his hardest to hide his bulge with his hands. Evidently, his poker face wasn't the greatest, as Elena glanced up from the paper and giggled, 
"It's alright Matt, I think you're very handsome as well." 
He blinked a few times, his mouth open as he tried to come up with something, anything to explain his state, the teacher petting him on the head, 
"It's natural, you can't control it, nothing to be ashamed of. My boy just reached his puberty a few months back, and if I couldn't handle a few erections in my face I couldn't get anything done." 
She giggled again, setting down the notes on his project, 
"But it is very flattering, I guess I made the right choice with my clothes this morning~" 
"I'm sorry, I really didn't mean to.." 
"Oh hush, it's not so serious! No harm done, we can forget about all this. Unless…~"
"U… unless what?" 
She set down the papers, running her tongue over her sharp fangs as she grinned, 
"Unless you want to take this further~" 

Matt's brain took a moment to fully register his teacher's words and the sudden sultry look in her eyes, his ears ringing with his heartbeat as he slowly steadied himself, glancing at the closed door just to make sure the pair were all alone,
"You… uhh… you want to…" 
"I'm just saying, you're a handsome young man who seems to at least have some interest in me, I haven't had a guy to fool around with in a while, and we've both got some free time on our hands. If you're not at all interested, then that's fine…" 
She winked at the boy as she turned around, picking up her books as if she was about to leave, his slightly panicked words making her grin, 
"No, no, I'm… definitely interested!" 
"Well then~" 
She hopped up onto the table, spreading her legs slightly as she lifted up the hem of her skirt, giving Matt a proper view of her crotch, a slight cameltoe visible in the red fabric. He huffed and muttered under his breath, taking one last look at the door and the windows, 
"Fuck…" 
He stepped closer, his tail wagging like an excited puppy as she snatched up his hands and placed them both on her tits, pulling him in for a quick kiss as he gently squeezed her breasts. Both of the foxes panted as Elena licked Matt's neck, her hand wrapped around the back of his head, slowly persuading him to move downwards, 
"How about you put that maw of yours to work on something else~?" 
Licking his lips, he knelt down in front of the desk, leaning closer until his muzzle was hovering right between her slightly muscular thighs. With shaky breaths, he slipped one finger under the panties to pull them aside, her feminine scent hitting his nose, a droplet of her nectar leaking down her black spade. The teacher threw one of her legs over his shoulder, Matt grabbing onto the other as he dove right down, stuffing his tongue inside of her cunt. As she huffed and moaned, trying desperately to keep her voice low, he zipped down his fly to pull out his cock, stroking himself as he tongued the Fennec. Her legs pushed him in deeper, tightening around his head as she leaned back, the whole desk gently rocking back and forth as she ground her crotch against him, 
"Oh god… keep going, don't stop!" 
He followed her instructions, digging his tongue deeper into her pussy, his shaft sliding more out of his sheath with every stroke of his hand. 

Matt ate out his teacher, his nose constantly bumping against her clit as he lapped at her slit, her juices running down his mouth and soaking up into his shirt, the back of her skirt completely damp with a mixture of her delicious nectar and his saliva. She picked up and bit down on a pencil to stop her moans from carrying out into the hallway, her ears flopping all around as she humped the younger man sandwiched between her thighs. Her whimpers grew louder and higher pitched, her whole body tensing up as his tongue assaulted her clit,
"Fuck… I'm… I'm gonna cum!" 
A squirt of her juices showered his face as he opened up his maw to catch most of her orgasm, her hand and legs keeping him pinned down against her canine cookie as she quivered in a state of absolute bliss. Finally letting him go, Elena collapsed down onto her back, lying on top of her desk and panting heavily as the silver fox pulled himself up, one hand running up and down her thigh as his other paw worked his dick. Still recovering from her orgasm, she reached out to grab his length, stroking it with her fingers, his tip pointed at her belly and crotch as she jerked him off. Already being at the point of bursting beforehand, her handiwork made Matt grunt and pant, his knot trying to escape his fly as his load shot out on top of her, coating her shirt and her bare spade with ropes of his seed. Both canines stayed in silence for a few seconds before the Fennec took her cum coated fingers and pressed two of them into her cunt, huffing as she gave herself a few thrusts. She pulled the digits out and wiped them on the fur on her leg, smiling slightly sheepishly as she sat back up, 
"Sorry if I spring that on you out of nowhere, it really has been a little while since I've been with a guy, I guess I was a little pent up…" 
Matt leaned against the desk, still part way out of breath, 
"Heh… it's alright, I know the feeling." 
"You know, if you want more than just a quickie, I'd be free tomorrow afternoon, at my place." 
He didn't need to think about it for long, giving her a nod and a smirk. She hopped off of the desk and pulled her skirt down to cover up the mess on her crotch, pulling a few tissues out of a box to clean herself up before pushing the box towards him,
"You ought to take a few up as well, for your shirt. Now run along, before you're late for your next class~!" 

Matt felt outright giddy as he jumped into his car and started heading towards the teacher's place, having spent most of the Friday evening and Saturday morning thinking about their little encounter. From what he could gather from gossip around the school, Elena had given birth to a set of twins a good few years back, her then-husband divorcing her shortly after that, leaving her to take care of the children on her own. The drive was about a half hour long, giving the fox plenty of time to stew in his own juices, needing to unbutton his jeans to make his erection bearable on the bumpy roads. He parked on the side of the road opposite the quaint house and quickly jogged up to the door, clearing his throat and combing the fur on his head with his hand before knocking on the door. Only a few moments later, the Fennec fox emerged, dressed only in a bathing robe, a naughty smirk on her face,
"There you are, I was starting to worry I might've scared you off yesterday~" 
"I don't scare off easily." 
The pair giggle as she opened the door wider, nodding behind her,
"Come on in, I've been keeping myself warm for you~"
Walking through the house, Matt and his teacher came to the living room, the TV playing some colorful cartoon, two large pairs of ears popping out from behind the sofa, followed by two curious stares. Elena chuckled lightly, watching as two cubs stood up to observe the stranger in their house, the kids both nearly identical to one another. The two seemed to be slightly under nine, though their smaller height made them seem a year or two younger at first glance, a cub in light blue pyjamas looking more inquisitive while the other in pastel pink pyjamas jumped up in excitement. Matt recognised the two somewhat, remembering that his sister had called them over to his house a few times in the past, though he hadn't ever really interacted with them besides a passing greeting. Elena smiled and pat her newfound lover on the shoulder, 
"Here's my two little rascals, Tony and Melinda. And here's my… student, from work. He's here to do some studying with mommy."
The girl leapt off of the sofa, running over to Matt, 
"Ooh, ooh, do you wanna play some Pawtendo with us!" 
The boy stayed on the sofa, seeming a tad more subdued but still thoroughly curious about the new male. Elena pet Melinda on the cheek, gently pushing her back towards the TV, 
"Not now sweetie, maybe sometime later. He and mommy really need to go study, and we'll need some peace and quiet to do it. So you and your brother stay down here, okay?" 
The two cubs both nodded, turning back to their show as the mother grabbed the fox's hand and pulled him towards the stairs, whispering, 
"Don't worry, they're not going to interrupt us as long as they've got cartoons to watch. Now c'mon, you and me have some serious 'studying' to do~" 

Elena led his student upstairs to her bedroom, a spacious room bathed in a gentle crimson glow from the sunlight streaming through the red curtains. She shoved him against the bed, making him stumble backwards and fall down on his back, letting out a slight yelp and bouncing up and down as the bed springs creaked and she giggled. The Fennec slowly rubbed her hands along his thighs, rubbing a thumb on the large bulge already trying to burst out of his pants, her fingers teasingly plucking open the button of his jeans, pulling his zipper down at an agonising pace. Matt squirmed from side to side as she abandoned his crotch, grabbing and lifting up his feet one by one to yank his socks off and toss them behind her before tugging down his pants, her delight obvious from her face as she laid eyes on his tight briefs, the front of them already stained with precum, his knot pushing up from his sheath, 
"Oh, you've been thinking about me already, haven't you~?" 
He nodded and grinned, his throat starting to go dry as Elena stood up, seductively untying the cloth band holding her bathrobe on her, allowing the robe to fall down on the floor to reveal her fully nude body, her spade peeking out of her cream coloured fur, her nipples perked and her crotch stained with the results of at least a handful sessions of masturbation, 
"Well you're not the only one who's been eagerly waiting for this~" 
Matt's cock pulsed at the sight, sending a glob of his precum through the air, landing on his belly. She bent down, looming over him as she slowly licked up the salty treat off of his fur, her hands pushing up under his shirt to lift it off of him, tossing it aside with the rest of his clothes. She moved her muzzle upwards, nuzzling and kissing his chest and neck before pushing her tongue into his mouth, the two canines moaning into each other as she laid down on top of him, his hands groping her ass cheeks as she caressed him. 

Matt groaned and ran his fingers through the soft fur of Miss Elena's back while she slid her body downwards, eventually ending up on her knees on the floor between his legs, her muzzle only a hair away from his cock. She took a long breath before blowing her hot breath on his shaft and balls, his ticklishness making her giggle. Continuing her teasing, she let her tongue glide around his base, just barely glancing his knot a few times, making him huff, the stream of precum flowing down his length only increasing from the foreplay. Deciding to have some mercy on the poor pent up boy, the Fennec finally opened up her maw and took his red rocket inside, staring off small with just his tip resting between her silky soft lips, her tongue bathing it as she began swallowing more and more of it down into her muzzle. Biting down on his tongue to keep himself quiet, Matt's eyes closed as he focused on the blowjob, her skills at sucking him off working wonders. Suddenly, he was ripped away from his world of bliss as the hot maw slipped away from his canine cock, the boy looking down in anguish to see what was going on. He flinched slightly as Elena quickly jumped up onto the bed and threw her legs up towards his head, her feet on either side of him as she crawled backwards until her crotch hovered above him. Understanding what she was expecting from him, he wrapped an arm around her flank to pull her cunt closer, slipping a couple of fingers from his other hand into his mouth to give them a nice tongue bath before sinking them into the Fennec's spade. She moaned and pushed down against the digits, forcing them deeper as she swallowed his cock again, taking it right down to the knot, her hands pumping his base as she sucked him off. She felt his hips beginning to move under her, his shaft driven deeper into her maw and his shots of pre arriving more frequently. Only a few moments later, her throat filled up with his seed, a few small spurts of it shooting out of her nostrils, the unprepared fox quickly starting to swallow down the built up load of cum, her mouth filled to the brim. 

Elena gulped down the sperm with the silver fox's cock still buried in her muzzle, the muscles in her throat massaging his shaft as she swallowed mouthful after mouthful of his cum, his dick not even able to go soft by the time he was done with his orgasm. She pulled himself off of Matt, his red rocket coated in a thick layer of her spit, her lips wet from the blowjob as she rolled off to the side and onto her back. She splayed her legs wide open, her pussy opening up, a couple strands of her juices spilling onto the bedsheets under her flank. As he shakily climbed up onto all fours, the Fennec reached over for her nightstand, pulling a drawer open and tossing aside a few miscellaneous magazines and stacks of paper to reveal what she had stashed in the back of it: a small pink bullet vibrator connected to a remote. She grabbed the vibrator and stuck out her tongue, bathing the toy with her tongue before dangling it above her spade, her hungry eyes staring at Matt, 
"I think a young man like you has enough stamina for a second round, right~?" 
Grinning and nodding, he crawled up to her, kneeling below her as she giggled, his dick resting on top of her slit. With a press of the remote, the pink vibrator came alive, buzzing as she pressed it against his tip, slowly moving it up and down his shaft as he moaned. Another flick of her fingers shifted the bullet's gear up, vibrating even harder, the boy sucking in air through his teeth as she turned it all the way up, the fur on her crotch and belly staining from the sprinkling of his precum. Elena set the remote down and spread her pussy lips open, her other hand holding the vibrator against his tip while guiding his length down to her entrance, pushing him and the toy inside of her at the same time, the duo both moaning in unison. 

Matt collapsed on top of his teacher, stuffing his muzzle between her breasts and grabbing handfuls of her fur as he tried to keep himself together for as long as he could, his already sensitive dick being stimulated by both her and the toy. As he rammed his shaft down into her, he could feel both her soft and slick walls gripping him as well as the vibrator still massaging his length. Elena pulled him closer to her body, her hands rubbing his back as she barked and moaned, coaxing him to sink further inside of her. He was more than happy to oblige, stuffing his shaft all the way down to his knot in her wet spade, her pussy easily swallowing up his bulging knot after she had spent the whole morning playing with herself and preparing herself for the boy. After tying her, he gave a series of short thrusts with the knot still inside before yanking it back out, pounding her with a few longer thrusts, and then slipping the knot back in once more. He continued with the same rhythm for a while, the bed shaking from side to side, her squeals mixing with the springs screeching, his muzzle switching between licking and nursing on her tits, nibbling on her neck, and kissing her. Matt finally couldn't hold on any longer, his loins on the point of erupting any second, his voice shaky and hushed as he moaned out to her, 
"I'm… gonna cum!" 
Elena wrapped her arms around him to hold the fox inside of her slit, her mind already made, not caring about the fact that he wasn't using a rubber or that she wasn't on the pill, 
"Don't pull out~!" 
The words whispered into his ear only made his orgasm even more powerful, his legs shaking as he rammed himself balls deep and let his huge load go, her womb immediately coated in his virile seed. She clenched up to keep as much of the cum inside of her as she could, the vibrator still rumbling sandwiched between his meat and her walls, keeping up the stimulation even when neither of the two were moving. 

Matt felt himself very nearly black out for a moment, his vision starting to slightly blur and tunnel as he reached the peak of his orgasm, his face buried in the woman's chest fluff as she groaned and stretched her legs and toes. The vibrator was still whirring away, sending shivers down the pair's spines every few seconds, the amount of over stimulation being at a level where it was nearly painful. He slowly pulled his shaft and knot out of her, letting it lay on her lower belly as he rolled on his side slightly, still mostly laying on top of her, the bullet vibrator slipping out alongside the dick and skittering around the bed between her legs for a moment before she reached for the remote to turn it off. The fox's tip still let out the occasional small spurt of cum, marking Elena as his by drenching the fur on her belly with it. Neither of the two moved an inch or said a word for the next handful of minutes, both simply breathing and panting, the Fennec staring up into the ceiling while Matt had his eyes closed, his thoughts a frenzy of different questions and doubts. Just in the last few weeks alone, he'd gotten involved with several different ladies, just about every one of these relationships extremely taboo, able to quite easily ruin the rest of his life should they come to light. Not only that, but he had also pumped his seed inside of these women, making the situation even more risky. But no matter how much he tried to debate himself, the idea of impregnating his sister, his mother, his sister's friends, or his teacher didn't seem any less wonderful. Eventually he pushed his worries to the side, deciding to simply enjoy everything he could to the fullest, a big smile on his mouth as he nuzzled his face into the side of Elena's neck, taking in a deep huff of her rose-y perfume. She returned the gesture, hugging him with both hands and sighing happily, the duo resting in an embrace for a few more minutes before suddenly her phone rang, snapping them back to reality. She grumbled quietly under her breath, pawing at her nightstand as she tried to pick up the phone before answering it, 
"Damnit, I swear if it's those phone marketers again, I'll… Hello?" 
Her expression changed from annoyance to a more serious one after a moment of muffled speech, the Fennec sitting up and replying a few times, 
"Yeah… Sure… No, that's fine, I can… Yeah, I can do that… Alright, okay… Yep, bye!" 
She turned to Matt with a slightly embarrassed look on her face, scratching her neck, 
"I'm… really sorry, I don't want to spring this on you and I'm sure you've got better stuff to do but… could you look after my kids for just a moment? That was my coworker, she apparently left some really important files on my computer back at the school, and I'm the only one with the password for it. It'd only take an hour or so, probably… "
Matt smiled and patted her on the thigh, still laying down on the bed, 
"It's alright, I can do some babysitting. You go take care of that." 
She leaned down to kiss him on the forehead, 
"Thank you so much, you're a lifesaver! And I promise I'll make it up to you once I get back~" 

Elena quickly jumped out of bed and threw on some pants and a shirt, her secret lover taking the opportunity to admire her shapely backside as she bent over to slip on some socks. Matt likewise dressed himself, gathering up all of his clothes that had been tossed into different corners of the room, the duo emerging from the steamy bedroom with grins and a healthy red shade to their cheeks, a slight scent of sex still lingering around them both. Going downstairs, both of the cubs were still playing around in front of the TV, the mother snatching up a pair of shoes and putting them on as she called out to her kids, 
"Hey, you two! Mommy is gonna need to go run to the school real quickly to do some work, so Matt here is gonna take care of you until I get back, okay? You both behave now, I love you!" 
The cubs shouted out a bye in unison as Elena disappeared through the front door, leaving Matt standing next to the kids, both of them staring at him as he slightly awkwardly coughed, not entirely prepared for his impromptu role as the babysitter, 
"Alright then, you heard your momma, she'll be back in just an hour or two. You behave well, and I'll make sure you two get to enjoy some ice cream!" 
Melinda pounced forwards, grabbing onto his leg as she smiled up at him, 
"So NOW can we play some Pawtendo!" 
He laughed and ruffled her head, gently prying her hands free from his ankle, 
"Sure thing buddy. D'ya wanna join us as well Tony?" 
The somewhat shy little boy gave him a friendly smile and a nod, his promises of treats and video games seemingly winning the cub over. 

About half an hour later, Matt and the twins were all relaxing on the sofa, the older fox sitting in the middle with the cubs bouncing around on either side of him, the TV lit up with flashing lights and bleeping sounds as the trio played through some games, rotating the two controllers every so often. The siblings were a very curious pair, asking Matt just about everything they could think of, from his job to what he liked to do for fun to what his favourite flavour of soda was. He was beginning to let his guard down and settle into the rhythm, enjoying the peace, confident in the fact that his little side gig as a babysitter would turn out smoother than he would have guessed. The man's hopes were dashed however as Tony turned to the silver fox, opening his muzzle with a curious smile, 
"What were you and mommy doing upstairs? I heard lots of yelling and stomping!" 
Matt's face immediately dropped, his cheeks flashing red as laughed stiffly, 
"Uhh… well… we were… just studying, just like your mother said earlier, remember?" 
Melinda jumped against his shoulder, 
"Ooh, does mommy study with the other guys as well?" 
"What other guys?" 
"Some guys sometimes visit mom, and they also jump around on the bed like you! Usually it's at night though, me and Tony are s'posed to be sleeping but we sneak out and play spy sometimes!" 
Matt smirked as he listened to the girl speaking, Elena's struggle of keeping her sex life hidden from her nosy kids very obvious to him. He tried to hide his amusement, just staring ahead at the game, 
"Yeah, she probably studied with them as well." 
The boy leaned into the man's field of view, his eyes like a begging puppy, 
"Can we do that as well, I wanna study like mom!" 
The cub's paws shifted slightly, pressing onto Matt's lap, accidentally stroking his sheath as he huffed. He could just steer the kids away from the subject, distract them with some candy or something, and he wouldn't need to worry about anything. On the other hand, the obvious opportunity was staring him right in the face, and he was very tempted to take advantage of it. His brainstorming took a few moments, his smirk returning as he put down his controller. He was already too far in the mire of debauchery and degeneracy, might as well go all the way, 
"Okay, I think I could teach you both a thing or two~" 

Matt stood up and turned off the console, turning around to his captive audience as he opened up his pants, pulling his jeans and underwear down to his thighs to expose his sheath, half of his cock already sliding out of it. The cubs stared with wide eyes, Melinda leaning forwards to get a better look while Tony blushed and gulped. The silver fox pulled his sheath back to let the rest of his length flop out, his voice calm and playful, 
"You two are gonna need to take your junk out as well if you want to play, why don't you help each other with those pyjamas?" 
Melinda eagerly jumped to action, her fingers grabbing at her brother's buttons and pulling them open, the boy trying to struggle against her for just a second before accepting her tugging his clothes off, eventually leaving him nude. She then laid back with her hands behind her head, sticking her tongue out at the heavily blushing Fennec kneeling above her, his sheath stirring as he approached her. Slowly and carefully, he opened up her pyjamas, her young spade peeking out from between her legs. Matt sat back down next to the pair, slowly stroking himself as he watched, 
"So, do either of you know what you're supposed to do with your naughty bits?" 
The twins both shook their heads, the older fox grinning, 
"Well then, sit down and I'll show you~" 
The siblings sat on the sofa, side by side, as Matt knelt down on the ground in front of them, gently prying their legs open. He stuck a finger into his mouth, swirling it around to make sure it was fully covered in his saliva before pushing it against Melinda's crotch, the girl squeaking in surprise. At the same time, he bowed down and opened up his muzzle to gobble up the boy's entire package, his tongue slithering and slobbering at Tony's sheath and balls, coaxing the cub's cock to peek out. The Fennecs both moaned and squirmed around as the fox played with them, his finger pushing inside of the tight pussy while he sucked on the shaft. 

Tony wrapped both his arms and his legs around the head of the babysitter who was blowing him, letting out the occasional whimper as the rough tongue ground against his knot, the warmth of the mouth making him pant and gasp. Melinda slouched back on the sofa, pressing her nethers further down on the finger, sliding it deeper into her pussy, the new feeling of being penetrated awakening in her a hunger for more. Matt completely lost track of time as he taught the cubs the joys of sex, his eyes opening and his heart thundering in a panic as he suddenly heard the front door opening, Elena walking into the living room with her head down in her phone, 
"Heya cuties, I'm back! I stopped by the store on my way back and picked up some snacks. I thought that maybe you two might want to enjoy some chips while me and Matt go upst…" 
She stopped on her tracks, staring in disbelief as her student pulled his head up off of her son's lap, his lips and his finger sticky with various fluids, both of her kids completely bare and their pyjamas lying discarded on the floor. She stood still, her brain completely fried as Matt rose up, 
"Wha… what's… going on?!" 
"Heh… Uhh… the cubs really wanted to see what we were up to…" 
Tony jumped up, slightly out of breath and his stiff dick flopping up and down, 
"He's teaching how to play with you, mom! Wanna join us!?" 
Elena stared at the group in front of her for a moment, unable to even open her mouth, Matt suddenly gaining a devilish grin, 
"You know what, that's a great idea, why don't you join us~?" 
"No, no! This is… I can't…" 
Melinda piped up, her face flushed, 
"Aww, c'mon mom! It's real fun though!" 
The silver fox stepped towards the mother, gently setting down the shopping bag from her hands and coaxing her towards the sofa, Elena not putting up much of a fight, her expression still unsure, 
"You heard her Elena, it's really fun~" 

Matt gingerly nudged the Fennec mother, sending her stumbling back against the sofa, her ass thumping down on the cushion as she huffed. Tony immediately snuggled up to her, pushing under her arm as Matt quickly took off her pants, leaving her pussy exposed. The cub stared with fascination as he rubbed his palm on her canine cunt, making her moan and bite her lip, 
"This here is your mommy's pussy, and your dick goes here~" 
She instinctively spread her thighs open, a small trickle of cum spilling from her slit, her canal still loaded from her previous playtime. The silver fox grabbed Tony and set him down on his mother's lap, facing her, his tip pressing against her opening. With a little help aiming his tip and a coaxing hand against his back, he thrust inside of his mom, his muzzle resting against her belly as he groaned, the feeling of her walls squeezing his shaft making his head spin. Elena pulled him closer to her, his surprisingly generous size itching all the right spots deep in her loins, her maw open in a long and low moan. Melinda watched closely as the boy began breeding his parent, her snatch pressed against the sofa as she slid her body back and forth, humping the fabric. Matt sat down besides her, tapping his lap, 
"Get up here and I'll make you feel really amazing~" 
Smiling and giggling, she hopped up on top of him, the fox wrapping his hands around her and lifting her up slightly, aiming his wet tip at her spade. He slowly pulled her down on him, her tight cunt stretching open, Melinda howling with pleasure. He groped and fondled her growing chest with one hand, his other hand feeling the slight bulge on her belly that his cock was causing as it sank in her. 

The two couples fucked and humped side by side, Melinda riding on top of her babysitter while Tony plunged his mom's depths, both cubs in absolute heaven. Matt kept a watchful eye on the young boy, trying to pace his own finish for the same time that the cub would pop his cork inside of his mom. Elena huffed and moaned with every thrust, her son breeding her like a feral beast, his hips crashing into her at a breakneck speed, her juices and her creampie filling spilling out onto her legs. Finally, he could take no more, his muzzle twitching as he struggled to speak, looking slightly panicked 
"I feel… weird…" 
She hugged him, whispering into his ear, 
"Shh… just relax and let it all out~!" 
Her hand pushed on his flank, forcing his knot inside of her spade as he yelped. At the same time, Matt grabbed onto Melissa's sides and bucked up into her, his knot tying her virginal cunt, her back arching as she fell backwards against him and yelled out in bliss, the sofa soaked in squirts of her syrup. Both of the females were filled up, Elena's pussy overflowing with the seed of both her own boy as well as her student, Melissa's womb getting her first taste of seed. The males huffed and grunted as they unloaded, Tony holding his mother tightly while he had his first orgasm. A few moments later, all four of the canines were limp on the couch, both pairs still tied together. The cubs were nearly on the point of passing out, the two entirely spent and exhausted after a long session of learning. Matt leaned closer to Elena, kissing her on the side of her neck, getting a small smirk from her, 
"I told you it'd be fun~" 
"You're a really bad influence, you know that?" 
The two chuckled and nuzzled each other, closing their eyes.
