Max stopped moving forward momentarily as he processed this new and sudden sensation. Deep-seated, primitive urges were quickly starting to awaken from within his doggie brain. He had unwittingly discovered a warm and moist pocket for his cock, and it felt much better than the old stuffed bunny he had previously used for this purpose. As the gears turned in Max’s head, his ancient instincts began to take hold, and it became clear to him what he must do…
As her mind remained clouded from the blissful high she was continuing to enjoy, it was difficult for Amy to process the whirlwind of information that her senses were experiencing. But she now encountered a distinctly new sensation: a fullness in her mouth. It stretched her mouth wide, but not painfully so, as if she were taking in a large popsicle. However, it was nothing like a popsicle at all, as it was very hot and had a somewhat rough and leathery texture. Amy could detect a salty and slightly bitter taste at the end of it, which was situated near the back of her throat. A small amount of liquid seemed to be oozing out of it, landing at the base of her tongue. As her tongue automatically began to savor and slither across the rugged and unfamiliar object, Amy lazily began to open her eyes to get a better idea of what was in her mouth. At first, she was disoriented as she had not realized that her head was in an awkward upside-down position. She blinked the grogginess out of her eyes as she began to identify two furry hindlegs in front of her with a large dark sack that hung down from where the legs joined together…and a very prominent, red, quivering rod going from the base of this sack into her mouth. Amy took a second to process this scene before her eyes shot wide open in recognition and horror. Max…!
Just then and without warning, Amy’s lovable and loyal companion lunged forward and shoved the entire length of his tumescent cock down her young throat. She was completely unprepared as the red-hot shaft invaded past her tonsils and plunged deep down her esophagus. This made Amy gag immediately. Her abs contracted and her lower back curled as she attempted to raise her pelvis up off the bed, however she was pinned in place by Max’s furry frame above her. She tried to take a breath in, but her diaphragm moved in vain as her windpipe was blocked by the invading member. Her eyes watered and her vision became blurry. She could smell the pungent odor of Max’s ballsack, which had slapped her in the face with his initial violent thrust, and now rested on top of her nose. Amy struggled for air but was granted none. As her body continued to convulse in response to her now uninterrupted and involuntary gagging, she repeatedly tried to lift her hips up off the bed as she raised her arms up and grabbed the fur at Max’s flanks.
Max was in ecstasy right now, as he could feel his dick being continuously massaged by the irregularly contracting muscular spasms inside his young master’s throat. This sensation is way better than that old stuffed bunny, he thought. He now lay fully overtop the young mistress, straddling her face and torso, with his snout right at the confluence of her perfect thighs. His hulking form held her in place, and he knew her wild bucking would not be enough to dislodge his 90-pound body, not to mention his large penis which was now buried inside her throat. Better yet, he now had his original target within his reach, as he eyed the thrashing, panty-clad mound below him, taking note of the damp area of moisture in his master’s crotch, and the alluring scent emanating from within.
However, the primitive instincts that had informed Max’s decision to fully penetrate his young mate’s mouth were still at work, and he subsequently pulled his haunches back, retracting his phallus from within Amy’s throat back to the spot just in front of her tonsils. This allowed her to gather some much-needed air as she took several quick, deep breaths. But before she could do or say anything further, Max plunged his ramrod back inside the depths of her throat, closing off her airway once again. This ritual repeated itself every few seconds, with Max embedding his penis deep inside Amy’s throat, and holding it there while her gag reflex squeezed and milked his swollen meat, before withdrawing it for a few moments while she caught her breath, and then ramming it back inside. After several minutes, the initial resistance to penetration that Max had felt was noticeably decreased as the mixture of pre-cum that was continuously emanating from his cock, and Amy’s saliva, coated every inch of his massive shaft. After a while, Max was able to slip in and out of his young master’s mouth with ease.
Meanwhile, Amy was not having a good time at all! Apart from the shock and horror of being unexpectedly face-fucked by her family pet and struggling to breathe as a giant prick assaulted her windpipe, Max’s pendulous ballsack was repeatedly slapping her in the face with each penetrating thrust. She felt as if she was being constantly pelted by two smelly, rubbery eggs tied together with rope. Through mascara-stained tears, she could see that Max’s testicles had a greyish-blue hue and looked incredibly swollen. She knew this likely meant that he had not mated in quite some time, and as a result, his testes were bulging with sperm. The thought of her family’s dog cumming down her throat made her violently ill, and with the constant retching from her tonsils being continuously violated, she wanted to vomit. However, Max’s colossal organ occupying her throat made sure that no gastric contents ever saw the light of day. Amy observed as her dog’s scrotum began to progressively elevate after withdrawing from each thrust, until it became a tight package at the base of his penis. This coincided with a noticeable increase in the rate of Max’s penetrations. Now, Amy had only moments to gather air in between successive insertions, as the time between each became shorter and shorter. She knew this meant that Max was getting close to climaxing. Amy continued to struggle, attempting to push Max off of her by jerking her body and hips upward, but to no avail. He was just too heavy and did not budge. Amy tried to plead with Max and command him to stop and get off of her, but her mouth would be forcefully stuffed with cock before she could get out a coherent word, only being able to muster muffled grunts. Soon, Amy noticed something else begin to change. While Max was still maintaining a feverish driving pace, she noticed that the base of his cock appeared to be getting larger.
Max was committed now! He had successfully invaded his master’s steamy mouth, was able to ensure she would not escape despite her spirited struggle, and now with the ease with which his phallus was moving in and out of her mouth, he knew he was getting ready to empty his seed. While the stuffed bunny had always satisfied his urges in the past, he was never able to reach orgasm with such weak stimulation. He had almost inseminated a few female bitches at the dog park, but he was always prevented from doing so by the human female. But now, he was finally approaching climax, and he could not wait to bury his cock deep and unload into his young mistress. Although now, Max noticed that he was encountering some new resistance when plowing his dick into her throat. Whereas he was previously able to plunge the entire length of his rod inside with ease, now he was able to get all but the hilt inside. The rutting pup slowed down the pace of his thrusts and began to concentrate on placing more emphasis on driving the base of his shaft past her lips. This led to Max keeping the majority of his penis embedded deep inside Amy’s throat, so as not to withdraw too early and remove any gains achieved by the constant increased pressure of his evolving knot at her lips.
