It was time for one more final effort. As Jessica brought her widely splayed knees up as far as she could alongside her chest in preparation for her pull, Buster repositioned himself squarely at the center of her rump for one more well-targeted push. Jessica took a few deep breaths and mustered all of her might as she yanked herself quickly backwards. Just as her head and shoulders cleared the insulated trap once again, Buster’s haunches slammed forward into the back of Jessica’s firm thighs and ass. This time, the aim of his aching and pulsatile member was true as the pointed tip ripped through the soaked and weakened nylon fabric that had served as Jessica’s final barrier of chastity. Buster’s cock penetrated past her damp labia and plunged deep into her tight virginal pussy. Jessica could feel her hymen being shattered as the full length and girth of Buster’s colossal dick filled her vagina all the way to her cervix. She let out a massive scream that was immediately quenched as her face slammed back into a mouthful of pillows underneath the headboard. Jessica had previously only teased the outside of her vagina with her vibrator but had never been fully penetrated before. The pain was excruciating as she felt the engorged penis now begin to piston in and out of her pussy. Between the increasingly rapid and repeated forceful thrusts of her defiler, she could feel warm streaks of blood run down her inner thigh.
Buster was in a frenzy now. He detected success almost immediately when he heard the fabric tear with his final lunge and felt the soft barrier give way to a moist, warm, and tight hug. It felt fantastic to Buster, and his primitive instincts once again took over as he greatly increased the pace and depth of his hip thrusts, ensuring that his entire cock was enveloped in the euphoric snatch of his mate. Jessica let out a short cry with each thrust each time Buster’s 8-inch phallus buried itself deep inside her pussy. She was forced so deep into the suffocating pillows with the culminating plunge that her cries were barely audible above the panting of her betrayer. Jessica could not rationalize what was happening. How could her family’s lovable pet rape her and steal her virginity? She began to sob softly as Buster maintained his fierce tempo. While he had met some resistance with his first few thrusts into his young master’s vagina, it was becoming increasingly easy to slide his cock in and out as continual discharges of pre-cum mixed with her hymenal blood and vaginal secretions. As Buster’s haunches continued to slam repeatedly into his master’s backside, Jessica noticed with teary eyes that she could distinctly feel a swinging sack smashing into her clit. Her eyes became as wide as dinner plates when she realized what it was. It was Buster’s testicles! It felt like a pair of kiwis tied together with a rubber band were consistently battering away at her sensitive vulva. Jessica knew Buster was not neutered, as her mother was against it, and she figured he did not have much opportunity to meet female dogs in heat. Which meant that his balls were likely maximally engorged with sperm. Jessica instantly became nauseous and retched at the thought of her dog cumming insider her. She then vomited all over herself inside her cushiony cave. The pillow shoved in her face caused the vomit to spread outwards to the sides, coating her face and hair, with some of the acidic gastric juices entering and stinging her eyes. Fortunately, the floor of her prison chamber was made up of irregularly arranged pillows, so the expelled fluids quickly drained towards the floor. Jessica was not only being actively degraded by her family’s canine companion, but now she had effectively blinded herself in her own puke. She was humiliated, debased, in pain, and as she felt her dog’s balls slap repeatedly against her pussy and clit, she wondered when it would all be over.
This may have been Buster’s first mating session, but by now he felt as if he had a handle of it. He had felt the supple young female tense her abdomen and thigh muscles and arch her back a moment ago, but now she remained still as he continued to bore deeper and deeper into her now well-lubricated pussy. What had seemed like such a chore at first was now filling the pup with ecstasy each time he sunk his member into her snug mound, enveloping his entire penis up to the hilt. He even felt the rhythmic drum of his testicles against her cunt arousing, as his ballsack tensed and relaxed periodically in sync with his aggressive cadence. He was not sure what the purpose of those organs were, but he could tell they were full and heavy, itching for release. It was about this time that Buster felt a new sensation. The base of his penis was started to enlarge. While he was previously able to plunge his entire cock into the young girl’s soft honey pot, it had become increasingly difficulty with each thrust as he felt as if the hilt was becoming increasingly swollen. Buster compensated by increased the force of each push as he endeavored to force his entire cock inside his bitch.
Partially blinded and unable to wipe her eyes due to her arms remaining pinned and separated from her face by a mountain of cushions, Jessica gasped as she felt the pressure on the inlet of her vagina increase. She was still getting used to the full feeling in her pelvis as her vaginal walls continually stretched and her canine rapist continued his penile assault. The friction had decreased somewhat since the carnal invasion had commenced, lessening the amount of pain she felt, but now Jessica could appreciate a new girthy structure pounding her labia. The dog’s cock had easily reached her cervix after the first few thrusts, but now it felt as if something was preventing him from reaching full penetration. It felt as if a small baseball were trying to form, and her captor was committed to driving it inside her. Jessica’s head was swirling now, from the combination of the aching from being in a forced head-down position for what seemed like forever, to the vomit-induced stinging in her eyes with the nauseating stench invading her nostrils and providing a bitter taste in her mouth, to the building pain from the increasingly frantic and powerful vaginal assault by her betrayer. For a moment, the sensation in her loins had begun to feel warm and pleasant as the initial shock of her penetration wore off and the secretions and blood from her vagina and seminal fluid from her invader made the repeated violations bearable. However, the pressure was building once again and becoming increasingly intolerable.
Buster could feel a tension starting to build. The swelling at the base of his penis was nearing completion and his testicles had receded high into his groin so that his scrotum felt tight. He continually tried to insert the girthy knot into his lover’s snatch but was not making any headway. He decided to slow his tempo and exert more of his energy into each individual thrust and attempt to slowly introduce the engorged shaft into his young female master’s moist canal. As he did this, he could feel the girl’s legs tense up as she proceeded to move her butt by shifting her weight from side to side in an attempt to dislodge him. Buster knew he was buried too deep now to be ejected so easily. He pressed his paws deeper into the hips of his mate and continued his steady application of pressure to her pussy. The tension within Buster’s loins continued to build, and he could feel a wave from within begin to take shape. With a firm grasp of the young, deflowered female’s waist and a quick forward hip thrust, he felt the knot plop into place. He noticed the young master strain again and heard a faint muffled yell from within her padded sanctum, before she relaxed again moments later. He was puzzled why she would choose to hide her head and arms and present herself to him in such a way, but the mysterious actions of humans were beyond his comprehension. He was now locked to his bitch, with his knot fully entrenched insider her breeding canal. Buster stood still over his mate, with his forepaws latched to her hips and his haunches pressed firmly against her warm, firm thighs. Both the canine and human female were breathing heavy now, as both had been engaged in rather strenuous activity for some time. Buster was not sure what was going to happen next, but he felt the wave deep within his genitals quickly rise to a fever pitch. It was only a matter of time…
