Brittany’s New Puppy [ff] [bst] [inc]

Technically, the whole family adopted Sasha, but from an early age it became apparent that he was Brittany’s dog. He answered only to her call, slept at the foot of her bed, and spent every waking moment he could right by her side. At first Sarah was jealous, but in time she simply smiled at the dog’s antics. It certainly wasn’t anything personal, and the time the dog left her alone was simply more time to attend to her studies.

At 20, Sarah was bookish in both character and appearance, her quiet demeanor appropriately matched by her short cut blonde hair and plain, conservative glasses. Her usually flat face would occasionally morph into a subtle smile at an amusing anecdote, but she rarely laughed or made humor of her own.

Even Sarah’s body seemed to reflect her aura. She was thin, almost painfully so, and those who had never seen her workout might deem her fragile. She remained well toned, her legs and butt cut and tight from many a brisk jog, though try as she might she couldn’t enhance her small breasts. Sarah rarely stood out in a crowd, but she was content this way. Few bothered to bother her.

Her young sister was a different story. It’d be simple to say that 19 year old Brittany was Sarah’s polar opposite, but this wasn’t entirely true. Both girls were quite shy, but Brittany’s face was more relaxed and expressive, and she opted for contacts over restrictive glasses. Her bright laughter often came in bursts, and when she was relaxed conversation came more naturally to her. She preferred freedom and music to her sister’s more studious approach, often finding joy in the simple gifts of life.

Brittany wore her flowing blonde hair much longer than Sarah and stood a few inches taller, almost brushing six foot. She often skipped her somewhat haphazard workout routine, and while not fat was far from the twig her sister was. Her thighs and butt were ample and shapely, attracting many a glance from men. Her chest also filled out nicely, giving her a decided advantage over her older sister. Brittany was somewhat oblivious to the fact, but her appearance generally garnered far more attention than Sarah’s.

Despite their differences, both girls acted a lot alike. They dressed conservatively, rarely dated, and didn’t sleep around. Outwardly, they projected a picture of purity of innocence, the by the book definition of proper young women.
But underneath this thin facade lay the reason for Sasha’s canine affinity toward Brittany. A careful observer would notice him hump her leg far too often for a normal German Shepherd puppy, and he often pawed at her legs as if yearning to climb to a spot higher on her body.

The explanation for the dog’s behavior was Brittany’s dirty secret. From early in his life Brittany had experimented with Sasha, jerking and sucking on his little dog cock and encouraging him to lap at her dripping pussy. What had started as a horny teenage whim had turned into an obsession, and Brittany and Sasha played at every opportunity.

A few months went by, and Brittany developed a system of sorts. She was usually cautious and careful, only playing when the house was empty, but occasionally she’d take risks when horniness overwhelmed her. She was able to keep Sasha from getting too wild by sending him with Sarah on her jogs, and Sarah seemed to appreciate the company.

On one particularly fateful day, Brittany found herself alone in her house. Her parents were away for the weekend, and Sarah had elected to go out for the day with some friends. As soon as Brittany felt confident her parents weren’t going to return for something they had forgotten, she excitedly stripped off her clothes. Sasha seemed to sense the event unfolding, and as Brittany flopped down on the floor, spreading her pussy wide, the German Shepherd began to eagerly lap away, covering her entirely from the bottom of her slit to her blonde landing strip with his large tongue. Brittany threw back her head and moaned, more happy than ever to be alone. Even the closest neighbors wouldn’t hear her unless she screamed bloody murder.

As Sasha continued to lick, Brittany noted his growing dog cock emerging out of its sheath. Reaching out, she was just able to grasp it and give some encouraging pulls. Sasha had grown a lot as of late, and the small dick Brittany had once barely coaxed out of its sheath now grew to a full adult sized member. She admired the intricate veins running up and down the shaft, peeling back the foreskin as she stroked and eyeing the bulging tip.
Stretching out her head, she awkwardly sucked Sasha off while still getting the attention to her pussy, enjoying the pleasure in her loins and the salty taste filling her mouth.

A sudden cramp from the awkward position forced Brittany off her butt and onto her knees, stretching out an aching calf. As she stretched she suddenly felt paws on her back, and surprising strength forcing her down into a position on her hands and knees. Before she was fully cognizant of what was happening, Sasha positioned his paws on her thick ass, and with surprising accuracy maneuvered his thick dick into her snatch.

Brittany gasped, frozen by shock as the dog began to thrust into her. No amount of masturbation had prepared her to be penetrated so suddenly, much less by a massive German Shepherd schlong. Grimacing in pain, she tried to pull herself off Sasha, but the combination of her awkward position and cramped up leg made the maneuver all but impossible. Panic began to set in for Brittany, matched equally by Sasha’s excitement as he pumped faster and harder.

Suddenly Brittany felt an incredible swelling inside her, sending shooting pains up and down her body. To her horror she realized that Sasha had already knotted her, making further movement all but impossible. For all intensive purposes, Brittany was now Sasha’s bitch.

Tears of pain began to leak down Brittany’s face, and out of her mouth flowed screams and sobs. She swore at her own cunt, which felt as if it was being torn apart. Worst of all, she knew based on her experience blowing Sasha that it would certainly be a while before anything changed.

Unbeknownst to Brittany, this was about the time Sarah arrived back home. Her plans had fallen through, and she entered the door thoroughly miffed at her friends. These small concerns were shattered as she heard the sound of Brittany’s pained cries filling the house, chilling Sarah straight to the bone. She raised up the stairs to Brittany’s room, throwing open the door in panic.

The sight that greeted her eyes did little to alleviate this feeling. Brittany was completely nude, covered in sweat and crouched on the floor with the dog clearly deep inside her. Tears streaked down her face is, and in her agony she didn’t even notice Sarah’s presence.

“What the fuck?” Sarah let out, loosing a rare curse as she gazed in amazement at the scene before her.

Brittany’s head swiveled around, her face blushing despite the pain. “I’m… so sorry,” she choked out between guttural cries.

Sarah had no words, but came to her senses enough to take action. She moved toward Brittany and grabbed Sasha, fully intending on pulling him off her younger sister.
“Stop… don’t,” Brittany managed, struggling to make coherent phrases. “Stuck… has to… finish.”
Though Sarah didn’t understand the anatomy of her sister’s condition, the message was clear enough. There was nothing she could in the moment to help Brittany.

Sarah considered leaving the room entirely, but something deep in the pit of her stomach kept her from running away. She settled by Brittany’s head, stroking her hair and trying to calm her. It had occurred to her that Brittany’s screams might be loud enough to attract attention from others in the neighborhood, and the last thing she wanted for her sister was further embarrassment. However, Sarah’s pleas for Brittany to calm down and breathe went seemingly unheard, her only response a continued scream.

“I’m… sorry.” Brittany let out again between groans. Sarah looked in her sister’s eyes, overcome by pity. And yet, there was another feeling. Deep within herself, Sarah felt a primal arousal. Her sister’s nude, dripping body was causing her own pussy to leak, and the animalistic pounding Brittany endured only heightened the sensation. Sarah had known for a while that she had a thing for girls, but her own sister? These feelings were new, and far more powerful than any she’d every felt.

Drawn partly by shock and mostly by instinct, Sarah slowly leaned in, Brittany’s eyes widening as a shout died in her throat. In a moment that seemed like eternity their lips met, kissing with a passion neither girl had experienced before.

In an instant Brittany’s body relaxed, her mind far from the dog inside her as she hungrily kissed Sarah back, their tongues tangling in a wet embrace. There was almost a desperation to their meeting, built up by years of tension that neither had ever acknowledged, even to themselves.

The relaxation brought on by the kiss was exactly what Brittany needed, and though she was still in significant pain, pleasure began to seep into her from her abused pussy. She moaned deeply into Sarah’s mouth, a sensual expression rather than a panicked one. Sarah moaned back, her hands reaching up and cupping Brittany’s face as their mouths melted together.

Eventually the need to breathe broke them apart, both girls gasping and breathing hard. For a few seconds they couldn’t even look at each other, overcome by a flood of different emotions.

“Well that helped,” Brittany said simply, her voice less strained than before.

Sarah into her sister’s eyes with a smile. “Then we’d better not stop,” she replied. Their lips met again, and Brittany desperately wished she could wrap her arms around her slender sister as they kissed.

Growing ambitious, Brittany’s mouth soon moved elsewhere, kissing and licking Sarah’s sensitive ears and neck. “Oh Brittany,” Sarah whispered, her senses heightened like never before. As Brittany continued moving lower toward her collarbone Sarah interpreted the unspoken message, quickly pulling her shirt over her head and unclipping her simple white bra. Her small tits greeted Brittany’s eyes, and Brittany’s mouth followed soon after, latching onto a nipple as she sucked and nibbled. Sarah threw back her head and voiced her approval, groaning just as Brittany had when Sasha licked her slit.

Unabashed, Sarah thrust a hand down her jeans to rub her clit, unable to contain herself any longer. Brittany’s already stuffed snatch continued to feel better and better as Sasha shifted inside her, and soon the room was filled with a chorus of moans from both girls, complimenting by the sounds of a panting dog and Brittany sucking on Sarah’s succulent breasts. All at once Brittany felt a powerful welling deep inside her, and she was unable to announce her orgasm before it washed over, overwhelming her. Sarah didn’t require an explanation as Brittany’s eyes rolled back into her head and she became incapable of sucking Sarah’s nipples. Sarah was more than happy to simply enjoy the sights and sounds, and took the opportunity to strip off her jeans and panties, giving her fingers easy access to her dripping cunt.

After a few earth-shattering minutes Brittany recovered from her orgasm, her knees weak but the dog still firmly inside her. She looked up at Sarah, face flushed with embarrassment but a smile on her face.

“Enjoying yourself?” Sarah asked somewhat teasingly.

“Even more than I thought I would,” Brittany replied, leaning in and kissing Sarah. She pulled away quickly after, a different thought already on her mind.

“Bring that pussy over here and let me show you something Sasha taught me.” Brittany motioned with her head, indicating for Sarah to position herself pussy just below Brittany’s mouth.

“Do your worst,” Sarah responded, moving into the proper position and spreading herself wide with her fingers.

Brittany happily obliged, burying her nose in her sister’s blonde pubic hair as she licked and explored with utter abandon. Her experience with Sasha guided her efforts, and she focused on the areas she’d often guided Sasha’s eager tongue toward.

“Oh yes Britt, don’t stop,” Sarah moaned, lying back flat on the floor. Her already wet slit leaked even more of its juices, and Brittany was all too happy to lap them up. Sarah gently humped into her sister’s face, driving her tongue deeper and deeper inside her.
Despite Brittany’s inexperience, Sarah’s excitement more than compensated. Before long Sarah jubilantly exclaimed “I’m cumming!” for the first time in her life announcing her orgasm. Even more juices gushed into Brittany’s mouth, and Sarah’s orgasmic screams almost rivaled Brittany’s earlier screams of pain.

Sarah collapsed on the floor, and the stars seemed to align for Brittany. While her sister lay spent on the floor, Sasha let out a whimper, and Brittany felt a hot spurt deep inside her womb. This was followed by an explosion as Sasha drained his huge canine balls into her waiting cunt, shooting strand after strand. Cum dribbled past his cock as he filled her to the brim, and as he finally redacted his member the excess practically flowed out onto the ground.

Now it was Brittany’s turn to collapse on the ground, exhausted and her pussy abused beyond belief. Sarah quickly recovered sufficiently to crawl over beside her sister, giving her thick butt a playful slap and gently rubbing her back. As Sarah surveyed Brittany’s cum soaked snatch, she found herself inexplicably drawn toward it. To both girls’ surprise, she bent down and gave it a generous lick, gathering up a mouthful of dog jizz as she did. Lying down beside Brittany, she then kissed her deeply on the mouth, the two finally wrapping their arms around each other as they swapped the thick cum. After several minutes they pulled apart, swallowing what remained of the load and shakily sitting up.

“You know, I’ve tasted his jizz before, but it’s never been quite that good,” Brittany said with a slight laugh.

“Same. Except for the tasting it before part,” Sarah responded. Both girls laughed, reveling in their new found freedom and sexuality.
“I’m sure we can change that,” Brittany said, glancing over at Sasha lying exhausted on the ground.

“Yes, I’m sure we will,” Sarah replied, pulling her sweet sister into a warm embrace.
