Jessica stared at the houses and mailboxes as they zoomed by outside the car window. She let out a sigh that briefly fogged up the window.

“Something wrong, Jess?” her father asked from the front seat, keeping his eyes on the road.

“She’s been acting weird all morning,” Jessica’s mother added, turning to look at her husband.

Jessica rolled her eyes at her mother, who was sitting in the passenger seat, directly in front of her.

“Does mom really not know?” the 14-year-old golden retriever wondered silently. Jessica wasn’t entirely sure [i]why[/i] she was in a funk, but she had a pretty good idea. In fact, it was a moment she had been dreading ever since she had first learned about it in health class.

Her first heat.

Mark, Jessica’s dad, looked up in the rear view mirror at his daughter, noticing she was looking out the side window at the passing scenery. His eyes wandered down to her chest; her budding breasts were concealed behind a pastel green t-shirt. Mark’s gaze quickly darted back to the road. He opened his mouth as if he was going to say something, but decided against it.

A peculiar scent caught his nose as they drove. Jessica’s father subtlety sniffed at the air a couple times. He looked over at his wife, Lynn, in the passenger seat.

“Is it Lynn’s…?” Mark thought to himself, looking back at the road. “No, it couldn’t be...She just had hers a week ago…”

The puzzle pieces slowly started to click together for the middle-aged canine. He sniffed once more, trying to confirm that the musky scent swirling in the air was indeed what he thought it was. His eyes shot back to the mirror; Jess was still looking out the window. This time, his eyes wandered further south, stopping when they landed between his daughter’s legs. His eyes locked on her denim-covered crotch for a long couple seconds as if trying to peer beyond her clothes.

“Mark! Look out!” Lynn called out urgently.

Mark slammed on the car’s brakes, everyone's attention shooting forward.

A small squirrel scampered across the road carrying a nut in its mouth.

It took a moment for their collective pulses to return from orbit. Mark’s especially; he had been worried that perhaps the commotion had meant he had gotten caught or that maybe Jessica had noticed him staring.

“Geez! Guess someone needs their morning coffee!” Lynn joked as the family of golden retrievers continued on to the school.

They pulled up to Newfont High School at around 7:30am and parked in a spot in the faculty lot. Jessica’s father was a chemistry teacher at the high school, while her mother taught language arts at the adjacent middle school. It was tough for Jess, going to school where her parents taught, but luckily she hadn’t actually had any classes with either of them. Still, the other kids would always be teasing: “Woah! Jessica [i]Williams[/i]? Like, [i]Mr. Williams[/i]!?”

The three lovely, blonde dogs climbed out of the car, closing their doors behind them. Jessica slung her black backpack over her shoulder. Lynn gave Mark a quick peck on the cheek.

“So I’ll meet you guys after school,” Jessica’s mother reminded them, “Don’t forget I have that teacher’s workshop though, so it’ll be closer to 4:00.”

Typically, the three rode to school together, went about their days, and met back in Mr. Williams’ classroom around 3:30 to head home. Although, some days Jess would have killed to have just ridden the bus home like a normal high schooler. At least in a couple years she would have her own car and could drive herself to and from school.

Jessica and her father walked towards the larger brick building, while her mother headed off towards the smaller building. The two schools were actually connected by a couple hallways and shared some of their common facilities, like gymnasiums and cafeterias. It made for one massive campus catering to grades all the way from 6th to 12th. Even though she didn’t really “change schools,” when she entered the 9th grade, Jessica still felt like there was some kind of rite of passage that took place. It sucked going from the top of the totem pole back down to the bottom.

Mark and Jessica entered through the double doors at the front of the school. His classroom was up on the second floor while her locker was down a ways on the first.

“Alright pumpkin,” Jessica’s dad said lovingly, “I’ll see you later, okay?”

“’Kay,” Jessica replied and started to walk off.

“Hey, hey, hey – c’mon, where’s my hug?”

“Daaaaad,” Jessica whined, turning and trudging back to her father. Her parents were always doing little things like this that would embarrass her; didn’t they know she wasn’t a puppy anymore! Jess begrudgingly embraced her dad. Luckily, at least for the moment, there was nobody else around in the entryway.

Mark hugged his daughter, holding onto her slightly longer than usual. He sniffed again as he hugged her, being careful to be discreet about it.

There it was again.

Sure, there was the normal delicate, sweet smell that followed his daughter around everywhere...but there was something else there as well. A unique, feminine musk that Mark had smelled many times throughout his life. A scent specifically designed to appeal to the baser biology of males; to entice them and stir lust within them; a signal to them that the female it surrounded was fertile and ready for breeding.

Except this time it was different; it was lighter and yet somehow, much more arousing. 

Was it simply because he was thinking about the fact that the scent was coming from his own daughter? Was it because when he typically smelled it, it was coming from his wife, who was past her prime whereas Jessica was only just now entering hers?

Whatever the case, Mark could already feel the intoxicating effects it was having upon him. He could feel himself getting slightly firmer inside his own sheath. He let Jessica go, not wanting to tempt fate any further.

As she walked away, he couldn’t help but stare at her ass. Did she always fill out those jeans so perfectly? The way her cheeks shifted with her hips and the way her fluffy, golden tail swung back and forth in front of them was absolutely hypnotic. And with Jessica went the seductive aroma that had been surrounding her.

There was no longer any doubt in his mind. His daughter had to be in heat.

Jessica finally disappeared around the corner and Mark let out a sigh before grabbing the handrail and heading up stairs. He kept replaying the sight of her walking away, over and over in his mind as he took each step. Once he finally reached the top step and the smell of freshly brewed coffee replaced fleeting memories of other aromas, he finally seemed to snap out of it.

So far, Jessica had been completely oblivious to her father’s attention. In fact, she was confident that since her own mother didn’t know that she was in heat, that it was reasonable to assume nobody else would know either.

However, as the day progressed, it became clear it wasn’t going to be so simple.

In her first period AP History class, Jessica caught the cute red panda boy that sat to her right stealing more than a few glances in her direction. In the hallway a group of sophomore boys leered at her as she went by and the gray wolf among them howled as she walked away.

It was enough to make Jess self conscious. 

She hurried into the girl’s bathroom and looked at herself in the mirror. Jess even turned, peering at her backside as well, just in case. She didn’t look any different than normal. 

After hiding in a stall, she gave a quick sniff under her shirt; she didn’t smell any different – at least as far as she could tell. And none of the other girls had seemed to notice a thing.

Jessica recalled the effects a female’s heat could have on the males around her. She tried hard to remember the chapter of the book. Certainly if she was having that kind of effect on the boys, she would notice something herself. Right?

Well, there was [i]one[/i] thing she had noticed. She was certainly feeling hornier than she could recall feeling in recent times.

The young golden unbuttoned her jeans and pulled them down, along with her underwear, and sat down as if she was going to use the toilet. She took a quick peek underneath the stalls, verifying that the restroom was empty. 

Jess eyed the slit between her legs – it didn’t look any different either. Her first wisps of pubic hair were starting to come in; they were coarser than her fur, but still fairly light.

With her paw, she reached between her legs and brought the pad on her fingertip against her pussy lips. They felt wet. Wetter than usual. As she lifted her finger away, a thin strand of clear fluid stretched between her fingerpad and her clit. After spanning a good several inches, the string of Jessica’s juices finally broke, leaving a bit on her finger. She rubbed her finger and thumb together, amazed at just how easily her fingerpads slid against each other with the natural lubricant.

Jessica was no stranger to masturbating. She had known about her “magic button” ever since she was five, bouncing on her daddy’s knee and enjoying it a little [i]too[/i] much. Since then, she had pleasured herself many times – at first, grinding herself against pillows and stuffed animals before eventually graduating to using her own paw and fingers. Even before her first heat she had felt rather sexual, but this was like a whole other level of arousal and desire that her young body was being awoken to.

She dipped her paw between her legs once more, feeling that delightful tingle as her pads came in contact with her sensitive lips again. Jess slid her middle finger up and down her slit a few times before finally dipping it inside. She started to let out a soft moan and had to quickly lift her other paw to cover her mouth, quieting herself in the echoey bathroom.

But it wasn’t enough.

Her ring finger soon joined her middle finger inside her tight love tunnel. She curled them and wiggled them inside herself as she rapidly pumped her paw back and forth. Jessica couldn’t believe she was pawing off in the girl’s bathroom, but at the same time, she didn’t care. It felt amazing and was somehow different than the times she had masturbated before. This time, it was like scratching an itch; an itch that [i]needed[/i] to be scratched. She wasn’t choosing to do this; she [i]had to[/i].

It was then that she heard two girls, probably upperclassmen, chatting idly as they entered the restroom.

Jess quickly withdrew her paw and made sure to stay as quiet as she could. She listened to their footsteps and watched their shoes as they entered the adjacent stalls on either side of her own. The two girls fell silent as they exposed their bottoms and sat down.

“Ohfuckohfuckohfuck,” Jessica thought to herself in a panic. “They know. That’s it. I’m dead. They heard me-”

But before she could even finish the thought, the sound of the two girls urinating started up and they picked up their conversation exactly where they had left it.

“Yeah, it’s like he doesn’t even know I exist!”

“Right!? Ugh!”

“I mean, I know he’s a teacher and all, but damn – talk about stud.”

Jessica sat in silence, listening to the two girls babble.

“Did you know he has a daughter that goes here?”

“Oh really? Maybe that’s why he acts like we aren’t there.”

“Yeah. Probably feels uncomfortable showing his [i]true[/i] feelings knowing his little girl is around.”

“Totes. Because who could resist us!”

“Wait…” Jessica thought to herself as she listened, “Are they talking about dad?”

The two girls finished up and washed their paws before heading back out to the hall. Their conversation had morphed into an inane session of self-praise between the two girls and Jess had all but tuned it out.

She had forgotten that they were possibly talking about her father. Instead, that same itch was rearing its head again, commanding her attention. It was like her body knew the coast was now clear and demanded that she resume her prior activities.

Jess wasn’t one to disobey. 

She reached backed down but just as her fingers grazed her labia, the bell rang.

“Shit!” Jessica softly exclaimed. “I’m gonna be late!”

She quickly pulled her pants back up and washed up, hurrying down the rapidly deserting halls to her math class. She took a moment to pause and catch her breath outside the door; no sense letting everyone else know she had just sprinted here – even if that was the truth. Jessica tried to be as quiet as she could as she entered. But, when she stepped through the doorway her teacher took note, pausing mid-sentence and stopping what she was writing on the board.

“Ah, Miss Williams. Nice of you to join us.” Her tone was flat, unamused.

The other kids laughed and Jessica dropped her head and made quickly for her desk. She wanted to just melt away and disappear. Her math teacher noted her tardiness on the attendance sheet and resumed the lesson. Jess tried to take solace in the fact that at least nobody knew [i]why[/i] she was late.

When lunch time rolled around, Jess sat at a table with her friends, Maddie and Hannah. Maddie was a white feline with some black markings and splothces. Hannah was a brown mouse with large round glasses. The trio had been friends even since elementary school. As they ate, they chatted about their classes, homework, and boys. Jessica didn’t quite feel comfortable bringing up her heat, even though Maddie and Hannah were her best friends. She was pretty sure that Maddie had had her first heat, but not Hannah. However, that train of thought did cause her to remember the conversation from the bathroom.

“Oh! I heard two seniors talking in the bathroom earlier...I think they have the hots for my dad!”

“Really?” Hannah asked, taking a sip of her soda, not sounding nearly surprised enough.

“Yeah! Isn’t that weird!?”

Maddie and Hannah exchanged glances with each other.

“What?” Jessica asked.

“Well...it’s just...it’s not [i]that[/i] weird,” Maddie explained. “Your dad [i]is[/i] kinda hot.”

“MADS!” Jess exclaimed, pushing her friend away by her shoulder.

Hannah burst out laughing. “It’s true though!” she added, backing up Maddie.

“You too!?” Jessica added, looking at Hannah in disbelief.

 As the two girls continued laughing, Jessica noticed a few boys at an adjacent table who were huddled together, whispering to each other and looking her way. She watched as they played a quick game of rock-paper-scissors. The loser, a black and white skunk, stood up and wiped his paws on his jeans. His two friends urged him forward, going so far as to actually push him towards the girls’ table.

Jess’ friends stopped laughing as their attention turned to the boy that had come up to them. He was kinda cute and Jess was pretty sure he was a freshman. She couldn’t for the life of her remember his name though.

“Can we [i]help[/i] you?” Maddie asked pedantically as the skunk-boy stood there awkwardly.

He cleared his throat. “Ahem. No, I uh- I was just...So Jessica? If you ever need a bone to chew on...I’ve uh, got one for ya.” He snapped his fingers and gave her a wink before quickly turning tail back towards his friends. His pals were cracking up and greeted him with high-fives when he returned.

“It’s not very nice to make fun of someone just because they’re a dog, ya know!” Maddie called out at the boys before throwing her empty plastic soda bottle at them. The boys easily ducked, avoiding the incoming projectile. They didn’t even bother to reply and instead continued to jeer each other and laugh.

But Jessica knew they weren’t making fun of her for being a dog. They had an entirely different [i]bone[/i] in mind and an entirely different reason for making the comment that they did. Still, in a way she was grateful that her friends had taken it the way they had.

Maddie and Hannah turned to comfort Jess, who put on a brave face and shrugged off the unwanted attention. Once she made sure her friend was okay, Maddie turned back to the boys and flipped them off as she stuck out her tongue.

The rest of the girls’ lunch was uneventful and Maddie and Hannah left together as they departed for their math class.

As Jessica sat in English, listening to her teacher drone on and on about Euripedes, she felt that familiar itch, nesting somewhere in the back of her mind. She wiggled in her seat, rubbing her vulva against the plastic chair. A pleasurable tingling radiated out from between her legs. Jess scooched forward, bringing herself to the very edge of her seat. Subtlety, she rocked her hips, grinding her clitoris against the beveled lip of the chair. She had to bite her lip to keep from making any noise.

Her arousal kept intensifying. It was like the more she scratched that itch, the louder and more demanding it became.

Jessica just kept steadily rocking her hips, years of practice helping her find exactly the right angle and pressure to push her [i]button[/i]. The friction of her jeans and underwear helped to amplify the pleasurable feeling. However, before she knew it, she had pushed herself past the point of no return. She was going to cum and there was nothing she could do about it.

Jess let out a small squeak as her orgasm caught her by surprise. She lifted her butt slightly off the seat as her sensitive bits spasmed in ecstasy. Her breathing was uneven, but she did her best to keep it quiet.

“Are you alright Jessica?” her English teacher asked.

That snapped her back to reality quick.

She sat fully back down in her seat, feeling the wet slickness in her underwear as they pressed against her pussy lips.

“Oh...just, allergies,” Jessica fibbed, smiling innocently and doing her best to play it off. Her face flushed with embarrassment and her heart pounded.

“Ah, well...bless you,” her teacher replied before resuming his lesson right where he left it off.

Jessica looked around her anxiously, trying to see if any of her classmates had noticed her odd behavior. But they were all already back to taking notes, completely uninterested in her.

That is, all except for the boy sitting one row back and over from her.

He was a quiet, shy boy – a raccoon with typical gray and black coloring. He was looking right at Jessica, a look of mild confusion on his face.

“Ohshitohshitohshit,” Jessica frantically thought to herself, quickly facing forward again. “He knows! That boy just watched me come!” The young golden retriever’s cheeks flushed even more. “Not only that, but I just [i]got off[/i] in my English class! Surrounded by my classmates!”

Jessica was surprised she had climaxed so easily; normally it took her quite a bit longer to bring herself to the edge. But this time, it seemed like it was so easy. Still, that itch remained. She had thought that at least maybe since she had come, the itch would have quieted down some. But if anything, it had done the opposite.

Impatiently, she watched the seconds tick by on the clock above the door. All Jess could think about was getting home, going to her room, and pawing off until the cows came home.

When the final bell rung, signaling the end of the school day, Jessica gathered up her books and headed upstairs to her father’s classroom. When she arrived, the students were all gone and her father was busy cleaning the blackboard. He smiled at Jess as she entered, continuing to wipe of a series of equations that were written in chalk.

“Hey Jess!” he greeted her warmly. “How was your day?”

“Ugh,” she said, turning down one of the aisles of desks and plopping down dramatically, dropping her book bag on the floor.

“That bad, eh?”

“Yeah,” Jessica replied, feeling relieved that the school day was over. At least and there would be no more harassment from any horny, teenage boys. “Just...typical teenage drama,” she told her dad, hoping that would satisfy his curiosity and she wouldn’t have to explain further.

“Ah, I see,” her father replied. “Sorry pumpkin.”

“S’alright.”

Jess pulled out her math book and a spiral notebook and started on her homework. Her father returned to wiping off the blackboard, his nose twitching. He sniffed at the air.

There it was again. 

That lovely, intoxicating aroma. It was already filtering through the air of his classroom.

“Hey, uh Jess,” he spoke, turning back towards her, “Would you mind helping me out?”

She looked up from her homework. “Sure – anything is better than geometry!” Her tail, which was sticking out through the back of the chair, wagged joyfully.

“Would you mind clearing off the Bunsen burners from the counters? They need to go in the storage room on the shelf,” he instructed. “You’ll see where they go.”

“Sure!” Jessica enthusiastically hopped up, and made her way over to the counter that surrounded most of the perimeter of the room. She always liked helping out her father and when he would treat her like an adult and ask for her assistance with things. Even though this was just cleaning up science equipment, it still filled her with a bit of pride that he was relying on her.

Jessica gathered three of the burners, bundling them up in her arms and carrying them to the door in the back of the classroom. She carefully used one paw to open the door and flick on the lights, holding onto the burners with her other. Jess walked backwards through the door, pushing it open with her body and disappearing into the closet.

Her father quickly moved around his desk at the front of the room, moving briskly towards the desk Jessica had been using. Even just approaching where she had been, he could sense the aroma growing stronger.

Jessica reemerged from the closet, her arms now empty and went to pick up the next set of burners.

“Parabolas, eh?” her father said somewhat nervously. He pretended like he had been examining her open textbook.

“Yup. Pretty thrilling. Right?”

Jess gathered up the next several burners. Evidently, she hadn’t paid any mind to the fact that her father had moved over near her desk. It was his classroom after all, he could go where he pleased.

“Oh yeah…,” he idly responded as she disappeared into the back closet once more. “Very exciting,” he added, under his breath this time.

His gaze shifted to the seat and he bent down, sniffing at the chair that Jess had occupied only moments ago.

It was the most intense hit yet of Jessica’s teenage heat; she had left it lingering on the chair. He could feel himself getting aroused and excited by the second as he drew in the feminine musk through his nostrils. He was falling into a stupor until his daughter’s voice shook him from it.

“Not you too…,” Jessica whined wistfully. She was standing in the doorway of the closet, looking directly at her father. Her shoulders were slumped and she looked defeated.

Mark quickly stood up, trying to play it off. “Oh I was just...there was...I dropped…”

He could see she wasn’t buying it.

Jessica sighed. “All day long boys have been chasing after me and now…”

“Aw, I’m sorry pumpkin. Your first heat?” he asked, trying to be as comforting and sympathetic as he could. Normally, this would have been Lynn’s territory, but he saw no reason why he as a father couldn’t talk with his daughter about it.

Jessica nodded reluctantly. She could feel her ears and cheeks burning.

Mark walked over to his daughter and gave her a hug. She hugged him back, enjoying the familiar comfort of his warm embrace. He smelled nice, familiar.

“It’s completely natural Jess. Every girl goes through it at some point.”

“I know…” Jessica lamented. “It’s just...hard.”

“I can imagine,” her father replied, not wanting to assume or invalidate her feelings.

“And all day I’ve been so…” Jessica stopped, not sure how, or if, she wanted to even finish that sentence.

Her father finished it for her: “Aroused?”

Jessica nodded again, burying her face in her father’s chest, trying to hide from the embarrassment.

Even Mark was blushing a little bit. After all, it wasn’t every day that your little girl told you she was aroused.

“That’s also totally natural,” he spoke in a steady, reassuring tone. “There are some powerful neuro-chemicals at work in your body. Things like dopamine and oxytocin and…”

Jessica looked up at her father with an endearing smile. “Leave it to the chemistry teacher…” Her friends’ words echoed in her mind as she looked up into his eyes. He really [i]was[/i] rather attractive. How had she never noticed before? Was that a result of her heat as well – finding certain males more attractive?”

Her father smiled back and kissed her on the top of her head. “All I’m saying is, it’s only natural to feel so aroused. There’s no fighting those chemicals sometimes – especially at the levels that you’re experiencing them.”

“Yeah?”

“Mhmm,” he nodded, their hug extending well past the length of their typical embrace.

The truth was, it was becoming hard for even [i]him[/i] to fight off and resist those chemicals. The pheromones and scents coming from Jess were overpowering – in the best possible way. They were speaking directly to a primal part of his reproductive biology, demanding that he mate with this fertile young female. He could feel his body warming up, his cock becoming slightly firm inside its sheath.

“You know…,” Mark finally spoke, approaching the topic delicately, cautiously. “I could help you out with those chemicals...if you want.”

Jessica looked up at her father curiously, innocently. She didn’t understand what he meant.

“That is, I mean, maybe we could [i]both[/i] help each other out,” he continued.

His daughter’s face flushed dark red as she finally understood what he was suggesting. She was stunned. She couldn’t even speak. Jess’ mouth opened, but no words came out. Was he really suggesting that they [i]do it[/i]?

Most of all, she was surprised with herself. She would have assumed that her answer would have been an immediate “no!” But as she considered the possibility, all her reasoning seemed to dissipate into the air. The fact of the matter was, those very hormones that were causing her heat, were demanding the same thing of her that was being demanded by her father’s biology: [i]Mate[/i] with him; [i]Give yourself[/i] to him; Let him [i]mount you[/i]; Get him [i]inside you[/i]; Let him [i]tie you[/i]; Let him [i]breed you[/i].

Jessica sheepishly nodded to her dad, much to both of their surprises. She figured, “if it would help, why not? At least it’d be with someone you know, and trust, and love.”

“What about mom?” she asked softly.

“She has that meeting, remember?”

“Oh yeah…” Jessica still couldn’t believe what was happening, it felt like she was floating or like she was going to wake up from her dream at any moment. “What...should we do?” she asked innocently.

Her father looked at the clock before peering around the room. He nodded towards the storage closet door. “There.”

They finally dropped their embrace and headed for the back room. Mark double checked that the door to the classroom was closed. When he entered the storage closet, Jessica was standing there facing him, timid and unsure. He pushed the door, closing it most of the way behind him.

Mark hugged his daughter once more, bringing her in close. The warmth of her body felt nice and intimate. He looked down at her, causing her to look back up at him. Their eyes met, fixing on each other, the look behind them much more sultry than usual. Jessica’s father could see the need and desire swimming in his daughter’s eyes. He bent down, kissing her passionately.

Jessica returned the passionate kiss, opening her mouth and greeting his tongue with her own. Their hands roamed as the kissed over and over. Jess’ breathing was getting heavier, her heart pounding ever faster.

Mark reached down between his daughter’s legs, bringing is paw up against her privates. He rubbed her slowly, eliciting a soft moan into their kiss. He could feel the intense heat radiating from his daughter’s genitals, even through her jeans. The crotch of her jeans felt damp. 

Jessica pushed her hips down, grinding herself against her father’s paw. She needed it [i]so[/i] badly. Never before had she felt such intense arousal. That now familiar itch was back again, this time screaming, [i]insisting[/i] on satisfaction. Their tongues continued to dance as she rubbed herself against her father’s palm.

Finally, Jessica’s father broke their kiss, looking down into his teenage cub’s eyes. He brought his other paw down and unbuttoned her jeans. Jess just watched as her father started to undress her. He tugged at her zipper before finally pulling down her pants completely. Her jeans fell to the floor, gathering around her ankles, exposing her bare, slender, golden legs. Underneath her jeans, she was wearing a pair of plain pink panties, a small pink bow adorning them in the front.

Next, he undid his own slacks, dropping them and pulling down his underwear too. Jess watched intently, her eyes fixating on her dad’s privates. It was the first time she had seen a penis in real life. 

His pinkish-white penis had already partly emerged from within his furry sheath. His two large testicles hung loosely beneath. The tapered end of his cock glistened with moisture – precome.

Mark maneuvered Jessica, turning her around so she was facing one of the wire shelves. Needing no direction, being guided by instinct, she bent forward, bracing herself against the shelves. Again, instinctively, without even realizing she was doing it, she flagged her tail – lifting it high, presenting herself and revealing her willingness to mate.

Her father squatted behind her, bringing himself in close to her backside. He couldn’t wait to reveal what lay beneath that thin, pink cotton. 

He reached up, grasping the sides of Jessica’s underwear between his fingers and started to pull them down. They clung to her vulva, held in place briefly by the product of her arousal – her wetness. Mark continued to slide down his cub’s underwear until he released them, letting them fall around her ankles as well.

The sight was mesmerizing: her beautiful, naked butt; her tightly puckered tailhole; her quivering sex, slick with her young juices. He held onto her thighs and brought his face forward. Jessica let out a small “meep” as her father’s cold, wet nose pressed against the tender, pink flesh between her pussy lips. He drew in a deep breath, inhaling the heavenly scent of his daughter’s ripe fertility. His pupils dilated as he took a hit directly from the source. The well of her arousal taunted him with the pleasures that await. A thick drop of precome formed on his tip before eventually becoming large enough that it fell to the linoleum floor below.

Jessica’s father licked once, lapping his tongue against her eager young sex. The taste of her nectar was sweet, tantalizing, girlish. She let out a moan, not bothering this time to muffle the sounds of her pleasure. Modesty and concern for the outside world had completely fallen away.

There was no turning back now.

Mark stood, grabbing hold of his daughter’s hips and bringing himself close. Jessica closed her eyes and braced, raising her tail as high as she could in an effort to expose herself as much as possible. The pointed tip of her father’s cock slid easily between her labia, finding its mark with expert precision. He pushed his hips forward and his canine penis penetrated Jessica, claiming her virginity. As he continued to push inside, the remainder of his length emerged from within his sheath, sliding directly into her.

Jessica let out a silent moan as she felt a pleasurable fullness inside her vagina that she had never felt before. Her father’s cock filled her up more completely than her fingers ever could. It was a perfect fit, with every inch of her bare walls pushing against his bare shaft. She had no idea that she could feel so good; to have all the sensitive surfaces within her being stimulated all at once. Combined with the warmth of his cock, it was all too much for her young body to bear.

She climaxed at once, bucking her hips and letting out a pleasured whine as her body rewarded her for giving into its demands. Her father’s knot pressed against her labia. Mark waited as he watched, and felt, his cub cumming on his cock. The incredible tightness inside Jessica increased even more as her pussy clamped down rhythmically around him. He had to do everything he could to fight against his own urges; his urges that were roaring, demanding that he rut her properly, like the bitch in heat that she was.

Jessica’s orgasm finally died down, with her legs becoming steadier as she fully supported her weight once more. Mark had waited all he could; the intense warmth and tightness inside his young cub was becoming impossible to resist. He had forgotten that sex could feel [i]this[/i] good. Jessica’s insides were much warmer, much softer, and much wetter than her mother.

He started thrusting, sliding his full length in and out of her teenage hole. Her vagina gripped him, molding and contouring to his exact shape and size. He slid a paw up and underneath her green shirt, fondling one of her supple breasts, still inside her bra. Mark greedily pushed her bra up, freeing both her small mounds. He slipped his other paw into her shirt as well, laying against her back, taking up two pawfulls of budding teenage breast. His hips bucked against hers. He rubbed his fingerpads over her stiff and perky pink nipples.

Meanwhile, unbeknownst to the incestuous lovers, Lynn’s meeting had been canceled and she was making her way over to the high school. She wandered through the empty connecting hallways, waving and smiling at the occasional faculty or staff member she would pass by.

Mark stood up tall, continuing to pound into his young cub, holding firmly onto her hips. The sound of their mixed, heavy breathing filled the storage room. It was accompanied by the wet sloshing as his thick canine cock sloppily thrust in and out of Jessica’s greedy fuckhole. Mark’s testicles swung back and forth freely, bumping up against his daughter’s clit; Jessica started to moan in time with every thrust, her dulcet voice echoing softly in the small room.

As pleasing as their coupling was, they both wanted more. They both had that mental itch, begging for them to satisfy it. It was an unspoken need, but they both instinctively knew how to scratch that itch.

Jessica’s father hooked his paws around her hips, getting better leverage. His pace quickened to a blazing speed. His cub’s moans became nearly constant as his hips bumped into hers furiously. To the lovers, the rest of the world blurred; nothing else mattered but the feeling.

Lynn opened the door to her husband’s classroom. The room was empty, but she saw Jessica’s books open on one of the desks.

“Oh, maybe they went down to the vending machines for a snack,” she reasoned, stepping further into the room.

However, she noticed a strange scent in the air. Was that…? No… It couldn’t be.

The next thing that caught her attention were the strange sounds emanating from the back room: a rapid slapping, a strange metal knocking, and distinctly-feminine squeaking – all rhythmic in nature, all in time with each other. Lynn approached the door, which was still slightly ajar. The sounds grew louder with every step closer she took. She pressed against the door with her paw, swinging it open silently.

Before her were her husband and daughter, their pants around their ankles, engaged in the most primal of acts between a male and a female. Jessica was bracing herself against the metal shelf – the source of the strange knocking. Neither of them were aware of her presence. She was just in time to witness her husband’s final erratic, powerful thrusts. He slammed forward hard, lifting their cub onto her toes. He forced his knot into their daughter’s tight, awaiting entrance.

Jessica yipped as she was knotted for the very first time, but this quickly morphed into a pleasured whine. Lynn watched as her husband and cub climaxed together. Mark’s tail curled between his legs in a phenomenon that Lynn was well-versed with: his tail tugged up and down and she knew that Jessica’s father was pumping his load deep within their cub.

The flood of warm cum erupting inside of her made Jessica’s orgasm grow in intensity. Her knees buckled and she struggled to hold up her weight, her paws gripping firmly onto the metal shelf. Mark reflexively pushed his hips underneath his cub’s butt, helping her support her weight. This forced his knot even deeper inside of her; Jessica moaned loudly as the limits of her vagina were tested. More and more of her father’s seed was pumping forcefully into her young body.

[i]This[/i] was exactly what her body had been demanding. The itch was finally being scratched.

Her hips bucked wildly and her body spasmed. Powerful contractions rippled through her reproductive organs: her vagina writhed in waves, trying to coax even more cum from the penis buried within it; her uterus and cervix dipped repeatedly, bumping against his tip and trying to submerge themselves in his semen. It was a whole body experience; unlike any that she had ever experienced before. This time there was [i]purpose[/i]. This time her body knew it could be [i]bred[/i]. It didn’t matter that it was the very same penis that had given her life, all that mattered was that it was inside her now and filling her with warm, life-giving seed.

When it looked as though their climaxes were finally dying down, Lynn stood in the doorway and cleared her throat.

Jessica and Mark’s hearts skipped several beats and they turned to face their “visitor.”

“Lynn!” “Mom!” The two shouted in surprise simultaneously. Mark tried to take a step back, forgetting he was tied to their cub. Jessica let out a yip as her father’s knot tugged against her entrance, pulling her back with him.

“This isn’t...it’s not…” Mark stuttered.

Lynn just raised her eyebrow, awaiting to hear what possible excuse her husband had for the fact that he had just knotted their 14-year-old daughter.

“I’m in heat, mom!” Jessica stammered, also trying to defend herself.

“Exactly!” Mark played off his cub’s response. “Jessica just seemed so down and [i]really[/i] needed some help with her heat and so I offered to give her my help and she just needed it so badly and I figured as her father it was my job to help her with any problems she might have and Lynn you have to understand that I…”

His rambling trailed off as he tried to gauge his wife’s expression.

“Well. I guess what’s done is done. At least it was with you and not some random boy,” Lynn tried to reason. “I suppose you’ll be stuck like that for a while...I’m going to go take a walk.”

With that, she turned and marched out of the room, leaving her husband and daughter tied together in the chemistry closet.

“Oh fuck! Do you think mom’s mad?” Jessica asked her father, completely forgetting to not curse.

“Hey, language! And yeah she’s mad,” her father replied.

For the next fifteen minutes, the two tried to figure out how they could possibly make it up to her. They were both upset and had lost themselves in a moment of passion. Still, she didn’t seem nearly as mad as they thought she would of; Mark was sure he would have been killed on the spot.

After his knot had finally deflated enough, Mark was able to pull out of his daughter. His thick cock slipped out of her and hung heavily from his sheath. It was followed immediately by a torrent of his cum pouring out of his young cub’s freshly fucked hole. The clearish, white fluid splattered loudly onto the linoleum floor. Some dripped into Jessica’s underwear while yet more clung to her thighs, trickling down the insides of her legs.

Mark couldn’t believe how much there was; there was easily [i]three to four times[/i] as much as he normally produced when he did stuff with Lynn. Jessica turned around in place, shuffling her feet, her legs still constrained by her pants around her ankles. She eyed the large puddle of cum on the closet floor.

However, something else caught her eye: her father’s cock. Before it had been so light in color and a decent size, but nothing like it was now. Now, it was a dark, [i]dark[/i] red and HUGE. A droplet of their combined sexual juices collected at the tip as it dangled freely between his legs. With it now fully exposed, Jessica could see that it was distinctly canine in shape with its pointed tip and engorged knot. She couldn’t believe that all of that had just been inside of her! She didn’t know she even had that much room in there!

“Wow…” she said, staring at her father’s package.

“Yeah,” her father chuckled, feeling a bit prideful.

“I had no idea guys could get that [i]big[/i].”

“Yeah, you’d never guess all that was hiding inside my sheath, would ya?’

Jessica shook her head.

Father and daughter pulled up their pants and Jessica reached under her shirt and pulled her bra back into place. Mark got a handful of paper towels and wiped up the floor.

Jessica went back to her desk to work on her homework, hoping that would curry some favor with her mother. Mark finished cleaning up the burners and shut off the lights in the storage closet, closing the door behind him.

He sat down behind his desk and put on his reading glasses to grade.

“Dad?” Jessica piped up after several minutes had passed by.

“Hm?”

“You think we’ll ever do that again?” Jessica asked slyly.

Mark looked up from his work to see his daughter giving him a coy smile, that same look of lust from before, glimmering in her eyes.
