Shyly bursts through the door to his house, panting hard from the brisk run from the bus stop. Getting home before his mom and dad, he's home alone, and wastes no time in dropping his shorts just inside the door. His light blue brief underwear is snugly filled with a tight, youthful erection. He presses his paw against the offending bulge and moans as pleasure jolts through his nubile body. He's been in this state for the past thirty minutes when Alexandra, "The Beauty of Buoy Bay" Middle School took the seat in front of him on the bus. One whiff of the heady cocktail of her lilac scent and pheromones sent the boy's adolescent brain into a tizzy, lighting a fire in his loins and a throbbing stiffy that threatened to pop the seams in his shorts. And it didn't help that she was chatting away with Mikayla about the other girl's first kiss at a party the previous night. What he would give to have his lips against hers!

It’s with these thoughts that he reaches through the opening in the front of his undies and takes out his boyflesh. Fully hard and pointing straight up to the ceiling, at its full three inches; he wraps his fingers around it and squeezes. The hot skin-on-skin contact sends electric pleasure up his spine and makes his legs tremble. He tosses his backpack to the floor and leans back against the wall, slowly sliding down until he’s seated, legs splayed open. He strokes himself up and down, the friction setting off nerves all over his swollen, barbed tiger cock. He shuts his eyes and loses himself in his pleasure. He feels his insides shift as his body prepares his reproductive system to squirt out his preteen seed. His masturbation becomes smoother as thin rivulets of his nectar dribble out from the slit at the tip of his sex. His tight abdominal muscles tense and relax rhythmically, waiting to push out all he has built up inside his system. His striped tail lashes to and fro on it’s own. He lets his hips twitch up off the hardwood flooring and humps his paw as if it were a fertile female’s pussy. Visions of Alexandra bouncing merrily on his lap while he suckles gently on her budding breasts fill the blank canvas of his mind. Squirt inside me! Dream Alexa cries out. Fill my tiny body with your beautiful cubs! Unable to refuse his dream lover, he lets go of all resistance. His sensual moans ramp up until his voice pitches higher into a squeal of lust. All at once, the first shot of hot sperm jets forth between his fingers and splatters wetly onto the wood floor, as the blazing passion of orgasm rocks his frame. Two more sticky strings of white issue forth, adding to the growing puddle between his legs, before settling to a soft flow that rolls down over his fingers and staining his underwear. His paw stops its frantic stroking and just holds his cock, feeling it twitch in afterglow, and the faint pulse of his pounding heart. With a profound sigh, he opens his eyes…,

...And sees his nine year old cousin Victoria standing before him, eyes wide and her paws over her mouth. 

Panic battles with post-orgasm bliss in his brain. His eyes dart from his erect penis—still hard due to his powerful, youthful libido—the copious puddle of semen, and Victoria’s shocked expression etched into her pudgy baby face. Eventually, all he can say is: “I forgot Aunt Myri dropped you off to visit today.”

Like a deer in headlights, she stares for a moment longer before darting quickly away down the hall, with the sound of a slamming door to mark her escape.

Dammit! He curses to himself. Shy quickly stuffs his erection back into his underwear, uncaring of the mess he’s making in them and jumps up to follow her, leaving his other mess and his shorts behind. 

“Victoria!” he calls out as he makes his way down the hall to the guest bedroom. “What you saw back there was perfectly natural! Boys do it all the time, and girls too!” He reaches the bedroom door and pushes it open to walk inside. “I’m sure you could do it too if you tried!” Wait, what am I saying? She’s your cousin! 

“No! Go away!” a high pitched squeal comes from a mound of blankets on the bed. Shyly walks up to it and grabs the blankets and the little tiger cub hiding beneath them. Immediately she starts thrashing around, tangling up Shy and herself in the thick cotton. The boy wrestles with the bedsheets and pulls them away before Victoria’s legs batter him with repeated kicks.

“Calm down! Let me explain!” he says as he grabs her legs and pulls her upward. With her legs locked in Shyly’s arms and only her shoulders and head still on the mattress, her silky dress falls down to her chest, flashing lacy pink teddy bear panties to the boy, mere inches from his face. Unable to distinguish family from just any female, his horny sex twitches tightly in his undies. He tries to look his cousin in the eyes, but his urges force his eyes to constantly dart to the smooth curves of Victoria’s cotton-covered crotch.

“I’m sure you have many questions and I’d be happy to explain everything if you’d only CALM DOWN!” And like a spell, all the fight is instantly gone from the girl. She goes limp in his arms but refuses to look at Shyly at all, cocking her head to one side indignantly. He slowly sets her back onto the bed, but ready to take her back up should she start kicking him again. 

“There, isn’t that better? Now is there anything that you want to ask me?”

The girl’s eyes dart to Shyly’s then down to the bulge in his crotch, then back up. “What did you do?”

The boy sighs and sits on the opposite end of the bed from her. “Well, it’s called masturbation, which is just a long word to say that I was touching myself because it makes me feel good. And it’s perfectly normal and healthy,” he adds with emphasis. His eyes continue to treacherously glance down to the front of Victoria’s exposed panties. 

She seems to absorb this information for several long moments before: “And what were you touching?”

Another sigh. “Well, you know how you’re a girl, and I’m a boy?” Victoria nods. “So, boys and girls have different…”stuff” under their underwear. Boys have penises, and girls have...Well, girls have a lot of stuff, so for now let’s just call what you have a ‘vee’ okay?” Another nod. “Oh,” Shyly adds. “I think andros also have ‘vee’s but they’re really rare.”

Another few moments of silent contemplation as Victoria shifts on the bed to move to a sitting position like her cousin. “Why?” she squeaks softly.

“Why what?”

“Why do I have a vee and boys don’t?”

Shyly tips his head to one side at the curious question. “You...just do. That’s just how it is. Kinda like how you have green eyes and I have yellow eyes. Your vee is just what makes you a girl to begin with. If you had what I have, then you wouldn’t be a girl, you’d be a boy. That’s about it.”

“And...everyone knows about this?”

“Well, yes of course.”

“So...why do we have to wear clothes to hide it?”

Taken aback by another curious question, he frowns and ponders it for some moments. “Uh, well...it’s polite I guess? They’re called “private parts” so like, you shouldn’t just...show everyone, I guess.”

“Hmm. That’s kinda silly,” she retorts, looking down at her panties. “Mommy lets me be naked at home.”

Shyly suddenly feels dizzy as blood rushes to his face and crotch at the same time. “Uh, do you like being naked?”

Victoria nods again.

“Well,” Shyly begins cautiously. “If you wanted to...be naked...it, uh, wouldn’t bother me,” he suggests while trying to keep the desire out of his voice. Although, he reckons. She wouldn’t know what desire sounds like, or even means, to begin with.

“‘Kay,” she squeaks with a shy smile. And Victoria slides off the bed to her footpaws and begins undressing.

She takes the hem of her dress and pulls the garment up and off over her head, revealing her flat chest and fluffy orange-and-black striped fur. The pink of two tiny nipples barely poke through. She then slips her thumbs around the waistband of her teddy bear panties and pushes them down to her ankles and steps out from them, adding them to the pile of her dress. She stands up tall in the middle of the bedroom, fully nude and uncaring of the male eyes that are roaming up and down her vulnerable form. The bold coloration of her fur fades to downy silvery white fur at her crotch. Her erect posture makes her crotch look like nothing but featureless fluff, but even that is telling of her female sex.

Shy has seen drawn diagrams of the female body in his health classes, but never had he seen an actual living girl in front of him like this. Seeing his cousin here in reality makes Shyly’s head spin, heart pound, mouth go dry, as his brain sends out rapid fire messages of an overwhelming and instinctual desire to mate RIGHT NOW. 

“Now you,” Victoria prompts, pointing a finger at his clothes.

Another bout of dizziness. “Are you sure?” Shyly asks cautiously.

“Fair is fair, right? ‘Sides, I already saw you...do THAT...before, right? So…”

“I suppose you have a good point there,” the boy concedes. He rises off the bed and begins to remove his own clothes too. He pulls his t-shirt over his head and tosses it next to the pile of the girl’s clothes. His little briefs are tented obtusely with a vertical bulge and a dark stain over his tip that he’s been leaking into since the bus ride home. A glance to the girl shows her huge green eyes fixated right between the boy’s legs. With a deep breath to calm his hyperactive nerves, he gingerly lifts the waistband of his undies up and over his swollen member. He’s never been so horny in his entire life, and he feels that any mishap here could cause himself to pop right here and now (he also ignores a voice in the back of his head whispering that that wouldn’t be such a bad thing!). He peels the underwear down his legs to his ankles and can hear a sharp intake of breath from Victoria as he kicks them off to land on top of his shirt.

“Ta-da,” he says, a weak attempt at levity, which Victoria doesn’t seem to catch.

Victoria looks upon her cousin, humming softly to herself like in the way she does when she’s reading an interesting book. She takes a few steps closer, which Shyly tries to reverse only to find he’s backed up against the side of the bed. She leans closer still, until her muzzle is only a few scant inches away from Shyly’s erection. 

“I feel,” Victoria starts, her voice barely above a whisper, “weird. Tingly. And warm…all over.”

With adreneline-fueled senses, Shy can actually see Victoria’s nostrils flare as she breathes in her cousin’s highly aroused scent with the smallest of shivers. Her eyes flutter nearly closed and, still humming, leans ever closer, closing the gap with agonizing slowness, until her lips make contact with the pointed tip of the boy’s sex in the lightest of butterfly kisses.

Instant reaction. Shyly joins Victoria’s humming—more of a soft moan—as his erection twitches against his cousin's muzzle, leaking thin drops of precum onto her soft lips. Driven by instinct, her lips part ever so slightly to allow her soft, wet tongue to dart out and lap up Shyly’s nectar. Another shiver ripples through the girl’s slight frame, and her humming becomes huskier, more breathy, and indeed, with Shyly’s taller vantage, he can see her shoulders rising and falling in quick breaths filled with his scent.

Shy looks to the wardrobe mirror to his left, which frames the scene perfectly: Himself, face visibly flushed even through his fur, connected gently at his sex to Victoria’s small muzzle. Her tail lifted high behind her, tracing the curve of her spine. With another dizzying swoon, he catches sight of her paws: Left paw caressing her thigh and her right cupped against the downy fur of her sex. Not rubbing per se, but just THERE. Then it hits him. Beneath the stronger scent of his own arousal, there was another lighter scent, similar to his own but “cleaner” somehow, and in a way he can’t really explain even to himself, distinctly feminine. What Shyly wouldn’t give to be inside her head right at this moment, to experience the brand new feelings she must be having right now…

Then, unbidden, she opens her muzzle wider to slip Shyly inside her mouth. The extra-sensitive tip of his shaft down to the first row of barbs is suddenly engulfed by the wet, warmth of his cousin’s tongue and lips. A wet suckling sound is now added to the ever-present shallow panting of the cub couple. Shyly’s right paw rises to stroke Victoria’s soft headfur in long, slow caresses. He runs his fingertips along her rounded ears, bending them behind to scritch gently behind them in the way he knows she likes.

In a sudden thrill of panic, he opens his mouth in warning, only to close it shut with an audible snap, as it’s already too late. With profound, toe-curling bliss, he feels his first load of cum burst up his cock and squirt directly into Victoria’s muzzle. He covered his mouth with his paw to deaden the undoubtedly lewd noises he would be making, and with willpower he didn’t know he had, resisted the almighty urge to thrust his hips deep into Victoria out of fear of hurting her. If she was at all surprised by this sudden rush, she didn’t show it. A wet, throaty gurgling followed by heavy swallowing was her only reaction. She continued to suckle and swallow as nonchalantly as a newborn cub at her mother’s breast.

Just as Shyly begins to come back down off his sexual high, Victoria pulls back with a wet slurp and lets out a sharp squeal. Her legs buckle underneath her, taking her down to her knees and doubling her over. Both of her paws now pressing against her crotch, her body begins to tremble violently and face contorts into a mask of a strange new kind of pleasure. Nearly a minute passes like this, then a gusty exhalation as she releases the breath she was holding the whole time. Her body collapses further, as if all her muscles turned to jelly, until she’s flat on her stomach with her paws still firmly between her legs.

Victoria takes a few moments to catch her breath, and then: “What was THAT?” she squeaks, with an audible tremor in her voice.

Shyly had slumped into a seated position on the edge of the bed while Victoria was caught in the throes of bliss. It was shocking to see his little cousin, whom he visited and played with and helped tutor in school often in her short life, in such a lewd state of sexuality. His reverie was then broken with her question, and as promised, delivered an answer.

“I think...you just had your very first orgasm,” he replied.

The girl rolls over onto her back and gingerly removes her paws from her vee. Sticky strands of girlcum strech before snapping back to the downy white fur that is now matted and mussed with sex. She brings her wet paws in front of her face to examine the silvery strings of her nectar that connect between her fingers. “I dunno what that means, Shy…”

Shyly rises to his footpaws and gives Victoria his discarded shirt. “Here, clean yourself up with this.” The girl takes the shirt and begins wiping off the girlcum from her paws, and with a more gentle touch, wads it up and presses it against her sex to soak up her leavings.

“An orgasm,” he begins to explain, “is what you do when you masturbate. Remember that word? It’s what happens when I, uh, well when stuff squirts out of my penis. I...just didn’t know girls squirt stuff out too…Feels really good though, doesn’t it?”

Victoria curls herself up and rolls to her side to face her cousin on the bed. “It felt...something. Powerful. Like, my whole body was shaking and I felt like I was going to explode, or pee myself, or something. But...it wasn’t bad. I guess.” Victoria yawns widely, and her eyes drift closed.

Shyly smiles warmly down at his little cousin. “Sleepy? Let’s get you to bed, okay?”

“But, my clothes—”

“It’s fine. You said you liked being naked right?”

“Mhmm…” she agrees, flashing a small smile.

“Alright, let’s go.” Shyly bends down over Victoria and helps her to her footpaws, and walks her over to the bed. She flops in and Shyly tucks her in. Within a minute, she falls asleep.

Shyly finds his underwear and slips them back on, then takes Victoria’s clothes and is about to put them in the hamper, when a certain scent catches his attention. He sniffs the air, and realizes her panties are still lying in the pile of clothes in his paws. He tosses the dress in the hamper, but keeps the panties and gives them an experimental sniff. That same “clean”, feminine scent hits his brain again, but now more concentrated. He looks over at Victoria to make sure she’s still asleep, then presses the girl’s underwear to his nose, opening his mouth to let the scent wash over his scent glands, and breathes it in. His cousin’s intimate scent fills his brain like a strange drug, making him smile. Distantly similar to urine, but also much more, better, and different in a way he can’t describe. Lewd thoughts burn through his mind once again, and, with another glance at Victoria’s sleeping form, takes her panties with him as he leaves the guest bedroom and walks into his bedroom, closing the door behind him.

–––

“Shyly! Vicki! I’m home!” Moonlight calls out from the entryway of the house.

Shyly exits his room in a new change of clothes to greet his mother. “Hi Mom! Victoria is taking a nap in her room.”

“Hello sweetie, I’ve brought home dinner, so why don’t you go and get her and I’ll dish out in the kitchen?”

“Okay, Mom.” Shyly pads down the hall and gently opens the door to the guest bedroom.

The boy walks in right as Victoria is bending over to put on a clean pair of panties, giving him a full view of her backside. She turns to him at the sound of his approach, and giggles at the sight of his embarrassment. “Why so shy, Shy?” she quips with another fit of giggles.

Shyly splutters for a moment before pointedly turning away from the naked girl. “My mom says dinner is here so, uh, come out when you're done changing,” and with the message delivered his promptly retreats and shuts the door, but not before he catches the sound of more giggling inside.

Soon after, Moonlight, Shyly and Victoria are all seated at tray tables in front of the living room TV, with fast food burgers and fries on each of their plates. 

“So,” Moonlight starts. “How was your day? You two have fun playing together?”

The two cubs look at each other, him with a face of terror, and hers with one one of open mirth. 

“Sure did, Moonlight!” Victoria pipes up. “LOADS of fun!”
