“Happy birthday, Jen!”
Jensen gasped in surprised pleasure as her parents opened the door leading from
the house to the garage, and a huge Alaskan Malamute came bounding across the
kitchen floor in her direction.
“He’s beautiful,” she beamed, kneeling down to get a better look at him.
And he was. The Malamute’s coat was thick and glossy, and his eyes were bright
and warm with intelligence. Jensen had been searching for a heat companion on
the internet for months, but never in her wildest dreams had she imagined that
her parents would splurge on a purebred.
“We got a good deal on him from Mr. Morgan up the street,” her mother explained
as Jensen patted her new friend. “His name is Jay.”
“Jay,” Jensen tried the name out to see how it felt, and Jay barked, his tongue
lolling in what looked like a grin. “It fits him,” she said decisively.
It was Saturday night, and the Ackles were throwing Jensen her family birthday
party (her classmates had had their turn the night before). Yesterday, she’d
been put out to find no presents waiting for her when she got home from school,
but now she was glad that her parents had held back on giving her Jay. She
couldn’t exactly ditch out on her own celebration without looking extremely
rude—not to mention obvious—but at least Jensen knew that Grandma and Grandpa
Shaffer weren’t liable to live it up much past 8 o’clock.
She really, really wanted to get Jay behind closed doors and see what he could
do.
After submitting to a few pictures and some good-natured fussing, it was time
for cake. Jensen took her seat in the dining room, and Jay, already seeming to
sense that he was her dog, parked himself at her feet. She sneaked him bite-
sized scraps off her plate while she listened to her family talk, nodding at
the appropriate intervals and even laughing politely at her aunt’s suggestion
that she’d be ‘taking a mate any day, now.’
Underneath the table, Jay’s long, velvety tongue twined between her fingers as
she thumbed him a bit of frosting. The sensation hit Jensen straight in the
gut—her pussy growing wet with anticipation of what was to come.
Fortunately, none of Jensen's relatives decided to linger much past dessert.
Once the cake was gone and coffee was served, they started making their excuses
one by one, until it was just Jay, Jensen, and Jensen’s mother left in the
dining room with the post-party clean-up.
Jensen made an abortive movement toward the kitchen to start the dishes, but
her mom waved her off.
“Don’t worry about it,” Donna said with a knowing gleam in her eye. “I’m
guessing you want to go put your new present through his paces.”
“Mom!”
“I was young once, too, you know,” Donna groused. “Why, before I met your
father, I had the most beautiful German Shepherd—”
“I’m going, I’m going!” Jensen backed hastily out of the room, and her mother
dissolved into a fit of giggles at her expense.
“Have fun!” she shouted.
“C’mon, Jay,” Jensen grumbled as the dog wiggled out of his spot underneath her
chair and followed her into the hallway.
Jensen managed to avoid her father—and any other potentially scarring childhood
recollections—on her way up to her bedroom. Once she was inside, she locked her
door and rested her forehead against the cool wood, sighing in relief.
She and Jay were alone, and they had the rest of the evening ahead of them.
Gathering her resolve, Jensen stripped off her jeans and strode over to her
bed. She pushed the girlish, pink coverlet aside and crawled under the sheets
before patting the empty space beside her.
“Come,” she said. Jay titled his head at her, considering, before he jumped up
obediently. The mattress squeaked under his weight as he laid down.
Jensen wasn’t entirely sure how she should proceed. She’d heard things, of
course—whisperings among the older Omegas at school. She’d watched all the
requisite breeding videos in sex ed, too. But it was completely different now
that she was here: her body pulsing with need, and a warm, willing animal at
her disposal.
Jay regarded her with a friendly expression, and Jensen blew out a gust of air,
forcing herself to relax. Millions of Omegas had been doing this for ages, and
she could too.
Working her hand under the waistband of her panties, Jensen tentatively brushed
her fingers over her clit. It was hot and slippery. Arching her back, she
tugged her underwear down around her thighs, and Jay’s nose wriggled when he
caught her scent, interested.
“That’s it,” Jensen encouraged. He nudged in closer, and she spread her legs to
give him more room.
Jay’s tail beat a steady rhythm against Jensen's knee as he shoved his snout
into her crotch. His tongue curled out curiously, skimming over the pink,
softly-downed skin around her pussy, and Jensen forced herself to bite back a
moan.
Leaning forward, she buried a hand in the plush fur at the nape of Jay’s neck
and reeled him in. The dog let out a quiet whuff before he settled and started
to lick her in earnest. Laying back against her pillows, Jensen wetted her lips
and began to get herself off, fingers rubbing against her clit in a gentle,
circular motion
It felt amazing. Jay’s tongue was long and eager and talented. Jensen had only
begun masturbating a few months ago—and although the first time she’d
accidentally grazed her hand over her sex had been life-changing, this was even
better. Her whole body tingled, blood rushing to her greedy cunt as it opened
up, desperate for a knot.
“You’re such a good boy, Jay,” she crooned. Jay’s haunches rose off the bed.
His tongue was practically inside her now, and Jensen could see the pink tip of
his penis peeking out from its sheathe.
The evidence of his excitement pushed over the edge. Groaning, she came. Slick
dribbled down her thighs while Jay continued to lap at her intently, doggy
slobber turning her into a sloppy, soaking mess.
Quivering with the aftershocks, Jensen shoved lightly at Jay until he backed
off a little. The dog whined and worried the bedding with his paw, evidently
confused as to why she had put a stop to their fun.
With a quiet groan, Jensen summoned the energy to turn over and get up on her
hands and knees. Settling into breeding position—as easily as if she’d been
doing it her entire life—she wiggled her hips in invitation.
“C’mon, baby,” she said. “Up.”
Jensen wasn’t sure if Jay understood her, but he lavished a kiss against her
naked thigh all the same. His tongue caught the lips of her oversensitized
pussy, and she stifled a gasp into her pillow, wondering if she could stand
getting eaten out again. She wanted his knot so badly.
Jensen didn’t have to worry long, however. Jay was a heat companion, and he
knew exactly what to do with an ass-up Omega. Squeezing her waist with his
paws, he tugged her backwards until their bodies were flush, and then with a
quick, efficient hop he mounted her.
Jensen’s stomach twisted in anticipation. She could feel Jay’s soft fur
touching her everywhere, his watery precum joining the mess of slick and saliva
caking her skin. It took him a few tries, but he finally got it: his cock slid
against her vulva once, then twice, before shoving hard inside her—breaking her
hymen and taking her virginity for good.
It hurt. There was no two ways around it. Omegas were meant to be fucked, but
Jensen was still growing, and her pussy felt tiny around the impressive girth
of Jay’s 9-inch cock. He rutted into her roughly, paws scratching against her
sides as she made a low, wounded sound, completely overwhelmed by the sensation
of him moving inside her.
It was all she could do to lie there and take it.
Jay fucked her steadily for several minutes before his cock started to swell.
Jensen cried out and reached back to stroke herself, then—the pressure of his
knot against the inside of her clit making her crazy. Pleasure overrode her
pain, and it wasn’t long before she found herself approaching her second climax
of the night.
Suddenly, Jay yelped, and Jensen felt them tie off. Shuddering, she clamped
down on his throbbing knot and came with him. Her orgasm went on for what
seemed like ages before she sagged into the mattress, exhausted, Jay going with
her as they both collapsed into a sweaty, panting heap.
Together, they laid still for a few moments—Jay’s knot filling Jensen with load
after load of hot cum while he gently licked kisses across her face and
shoulders. With a happy sigh, Jensen snuggled closer to him and let herself
drift and dream.
Idly, she wondered if she might get pregnant. It wasn’t terribly likely, given
her age and that she hadn’t had her first heat yet, but it was technically
possible. She wasn’t on birth control, after all, and much younger Os than her
been bred by dogs.
Maybe it was just the hormones talking, but she thought it would be kind of
nice to have Jay’s puppies.
All told, they were tied together for a little less than half an hour before
Jay’s knot went down. With an impatient shimmy, he tugged backwards, cum
gushing out of Jensen as his cock pulled free.
“Guess I should’ve put a towel down,” Jensen muttered. Jay huffed and started
licking at the mess, and before she knew it, he was licking her again, and she
had to lie back down and close her eyes before she cut round three short by
coming immediately.
Jensen’s pussy was puffy and a little sore, but Jay’s tongue was gentle enough
to feel good. Hell, it was more than good. Jensen wanted to ride Jay’s face all
night long. She wanted him to fuck her over and over again until she was
certain that he’d knocked her up—her belly full of his pups and her tits
swollen with milk.
There was something so basely Omega about her desire that, for the first time,
she began to have an inkling of what it really meant to be an O. Sure, she knew
that she shouldn’t be getting this worked up over a companion—he was a dog, not
her Alpha—but the attachment she felt was inexplicably real and bone-deep.
She needed him.
Jensen orgasmed a third time with Jay’s tongue pushing his come back inside
her. Her hips bucked off the bed, and she felt herself crying a little as raw
pleasure coursed through her body—too much and not enough all at once.
She gave herself a few minutes to calm down before she reluctantly sat up,
swinging her legs over the side of the bed and pushing herself to her unsteady
feet.
“I think we need some clean sheets,” she told Jay in a conspiratorial whisper.
He wagged his tail playfully while Jensen petted him. “And maybe a towel or
two,” she added after a moment.
Jay woofed in response.
It was going to be a long night.
