Chapter Text
One afternoon, in a bustling city, a young girl name Lily strolled hand in hand with her mother Ivy. Lily had red hair, sparkling blue eyes, and her freckled cheeks flushed with excitement as they drew closer to her birthday present ahead. The girl smiled as she looked up at Ivy, whose auburn hair and freckled skin mirrored her own, though with a lovely pear-shaped figure that turned more than a few heads on their way. Her mother gave the girl a knowing smile in return, and the two giggled. Finally, they arrived at an unassuming alley, where a stray dog was wandering nearby. Lily's eyes lit up when she saw the dog, and she squeezed her mother's hand to get her attention, with a look of anticipation and and hint of something more lewd. Ivy gave Lily another knowing smile and said "Go ahead, sweetie, and have fun." Ivy watched as the girl skipped along into the alley, her giggles drawing the attention of the stray, who followed her with a wagging tail, before Ivy sat down on a nearby bench, and picked up a book from her purse to pass the time. Knowing from experience, her daughter would be there for a while as she received her birthday present, and a new chapter in the girl's life would begin.
As soon as Lily and the dog were out of sight, she was nearly shivering with a mix of excitement and nervousness, going through all the things that she had been taught for this big day. She slipped out of her pale green sundress, neatly folded it and placed it on a crate, revealing she had no panties on, so Lily's pale body was on full display for the stray dog. The girl bent down and let the dog lick her face, then opened her mouth and began making out with the animal, feeling herself getting aroused, and once Lily broke the kiss, saw that the stray was just as excited.
The girl then straightened up, turned around and leaned against a brick wall, looking back at the dog with a grin as she swayed her hips. The stray dog tilted his head, and wagged his tail even harder as he stepped towards the girl and started licking her glistening vulva, causing the Lily to softly moan in pleasure. Her heart now racing and cheeks bright red with lust, the girl then turned around and told the dog to sit.
She gave the stray a peck on the nose, then knelt down and giggled at the sight of the dog's red rocket, which twitched slightly. Lily's small hands caressed the dog's knotted penis, and she gasped at how warm it felt, so much different to how she imagined. The girl licked her lips, then opened her mouth and began sucking the dog, far more experienced than one would expect, causing the dog to pant heavily and whimper with pleasure. Lily bobbed her head until she could hear the stray yelp, then her eyes widened as the dog came inside her mouth, with such force that some of it leaked out of her nostrils. Lily managed to gulp down most of it, with only a little bit of cum dripping down her chin.
The girl then turned around and got on her hands and knees, presenting her backside to the dog and wiggled her ass as invitation. She giggled as the dog mounted her, his paws digging into her soft skin, and thrust his knotted penis into Lily's anus, causing her to gasp loudly, followed by soft moans as the dog began pounding her in the ass. Lily had climaxed several times as the stray dog finally knotted the girl in the ass, the sensation of being filled to the brim and the warmth of the dog's semen as he came inside her, made Lily let out a loud, primal moan.
The sweet sound attracted the attention of nearby strays, who now approached Lily, each with a look of primal desire in their eyes. Lily, still light-headed after her first orgasm from a dog, looked at the newcomers and grinned from excitement, there were all kinds of strays, large and small, old and young, all of the eager to give the girl her birthday present.
What followed felt like a blissful blur for Lily, and she loved every second of it. After the first dog popped his knot out of the girl, the other strays took turns fucking, knotting and coming inside Lily's mouth, pussy and ass, leaving no hole empty for long. Lily moaned and gasped as she was overwhelmed with pleasure, sometimes the dogs would double-penetrate her, and a couple times she was knotted in all her holes at the same time, her muffled moans echoing throughout the alley despite having trouble breathing. Sometimes Lily would fellate, jerk off or be irrumated by some of the dogs as well, while waiting for those with particularly large knots to dislodge themselves out of her ass or pussy.
By the time the dogs left the scene, spent and hungry, the sun had just dipped below the horizon. Lily, exhausted but happy, with a belly full of the dogs' seed, laid there on the ground in a puddle of canine cum, with more covering her body or leaking out of her mouth, nostrils, pussy and gaping anus. Footsteps then echoed throughout the alley, as her mother Ivy approached with a look of satisfaction. "I hope you liked your birthday present, sweetie" she said, almost whispering, then giggled as her daughter nodded. Ivy then bent down and gently held Lily in her arms, as she began making out with the girl, savoring the taste of her daughter and the mixed cum of all the dogs who had brought Lily so much pleasure.
Ivy whispered in Lily's ear "You did it, Lily, you passed the initiation perfectly. You look just like me when I was at your age, I'm so proud of you, sweetie." Hearing these words, Lily began to giggle, and soon the mother and daughter were both laughing, relieved that the initiation went well. Soon, more dogs could be seen approaching, and as the mother and daughter got into position, they both trembled with anticipation for the coming orgy. Ivy knew one thing for sure, Lily would soon get a little sister, conceived by the union of a woman and dog, the same way as she had been, just like Lily, and every woman in the family.
For hours, Lily and Ivy were lost in a flurry of being fucked and filled to the brim by the entire pack of stray dogs, each eager to drive the mother and daughter to new heights of pleasure. Lily took on a more active role this time, filled with newfound confidence, now that she knew what to expect and from seeing her mother do the same. The girl watched in awe as Ivy told one of the dogs to roll over, then straddled him and began riding the dog's red rocket with ease, clearly pleasured by this, but in a more subdued way than Lily.
When the girl attempted the same thing, she got so into the new sensation that the dog's knot slid into Lily's pussy, causing her to shriek and almost faint from pleasure. Her mother's soft laughter at seeing her little girl's antics echoed throughout the alley, until it was suddenly replaced with a gasp and moaning as one of the dogs began fucking Ivy's ass, the two dogs now both energetically thrusting in her ass and pussy.
Lily was still recovering from her climax when another dog took advantage of the girl's open mouth and began irrumating her, while another stray began fucking her ass, panting loudly from the feeling of Lily's anus, now tighter than before since she was still knotted in her pussy by the dog below her. Once the dog irrumating Lily knotted her in the mouth and shot his canine cum straight down the girls throat, Lily then glanced the side at her mother, who had already been knotted in her ass and pussy, and was now eagerly jerking off two dogs while making out with one of them. Once the dogs popped their knots, one by one, out of Lily and Ivy, other stray dogs quickly took their place, leaving no hole empty for long, and the semen left by the previous dogs made the thrusting smoother each time. Lily moaned loudly at an increasingly higher pitch from the sensation of one of the dogs' knot slipping in and out of her well lubricated anus, until the girl shivered with lust and rode the waves of her greatest orgasm yet. At times, especially when both were waiting for the dogs to finish inside them, Lily and Ivy made out with each other, caressed or held hands, and Ivy even dug in and licked her daughter's anus or pussy to soothe her holes and taste the mixed cum that had accumulated within the girl. Lily returned the favor, making up for her lack of experience with sheer enthusiasm.
This went on until the first light of dawn was visible in the sky as the mother and daughter arrived home, stumbling from exhaustion, with Lily half-asleep as she kept leaning on Ivy, but with a light smile on her face. Too tired to tuck her daughter to sleep, Ivy instead laid down with her daughter on her own bed, and embraced her as they drifted to sleep. It was almost noon when they finally got out of bed and took a shower together, washed off the dried canine cum off their bodies while sharing a passionate kiss. When Lily and Ivy came down the stairs, the whole family -all women of different ages, born from the union of woman and dog- gathered around the girl as they smiled and cheered. She was hugged and kissed by each family member, and licked by the three dogs living there as well, and was given a beautiful necklace with a little pawprint design, a symbol of Lily entering a new chapter in her life, and keeping the secret family tradition alive.
