“Hey neighbor.” Cozy Glow asked, looking childish and cheerful at Tirek. “Wanna be friends?”
“Of course not, you pathetic little-.” Tirek replied, showing complete apathy for the foal’s words. But an idea suddenly sparked in his devious mind. “Actually. It is quite fortunate you were sent here.”
“W-why?” Cozy asked, more than a little worried over what the centaur was planning. Her fears were only intensified when she saw Cerberus get up with a grumbling growl. “W-what are you going to do to me?”
“Me? Nothing.” Tirek smirked, rubbing his hand through the cage and at the large dog. “But him...oh he’s gonna do something.” The foal was backing against her cage, terrified over what was about to happen. “You see, being locked up here is so boring. And I was getting tired of listening to his annoying whimpers. So, he’s going to play with you.”
Snapping his fingers, Tirek commanded Cerberus into action. The massive dog jumped at Cozy’s cage, breaking it with ease under his bulk. For a second the three headed beast started at its prey. Cozy was shivering in fear, flapping her wings but unable to make a break for it. Sniffing the air, he looked to Cozy before bending down, readying himself for the next leap. With a pounce, Cerberus landed on the filly as she tried to fly away. The large dog pinned the little body under his weight. This alone should have froze her in terror. But it was the warm and soft flesh feeling plopping along her little flank.
“You see, he’s a bit of a horn dog.” Tirek commented, watching with glee over what was to come. “And we don’t get many females in Tartarus. So whenever we get one, he likes to play with her.” Cozy tried to struggle, but her wiggling only made it easier for the huge, slick dog cock to line up with her unwilling snatch. “Oh yeah, keep flailing. He likes when they fight.”
Cozy continued to fight, but as she struggled to free herself, the wet, precum dripping cockhead against her pussy lips. But just as the dog was rearing to ram itself into the foal’s tight, virgin hole, her sudden movements caused him to miss. Instead of her pussy, which could stretch with time, Cerberus’ cock broke into Cozy’s even tighter asshole. She let out a breathless scream as she could feel the girth of dog cock half way through her body. Her insides and organs were pushed forward inside her as the dog settled for a moment.
“It hurts! It hurts!” Cozy cried, pain filling every fiber of her being as the cock was rupturing her anal cavity. “Take it out! Take it out!”
“Not likely.” Tirek explained, showing a great deal of amusement in Cozy’s suffering. “Once he’s started, he won’t stop until he’s satisfied.”
Cerberus started to pant, his chest heaved as his body began to move again. Cozy felt her insides being shuffled from the monstrous cock sliding in and out of her ass. Her anal wall breaking and bleeding from the rough humping the large dog was doing. She could hear and feel his hot breath at the back of her neck and head as he started to drive himself deeper in the foal’s hole. The thick and now hard cock rubbed within, making no care how painful it was to the foal being raped. It was an agony she had never even believe could exist. She felt as if the cock was going to break through her body; turning her into a living fucktoy for the hellish guard dog.
It was several long, and painful minutes before Cozy’s ass loosened up, the precum and blood action as lubrication for Cerberus’ thrusting. The dog’s cock swelled a little as it slid itself in and out, ramming itself deeper and deeper into the foal’s body. She could feel her bulging belly pressing against the warm, stone ground. Bigger and bigger, Cozy could feel her organs being pushed aside, her inner parts being stuffed with cock. The pain numbed all other senses, making it impossible to know anything else. She coughed, gagging on the feeling, like her organs were going to be fucked out through her throat.
“Looks like he’s getting close.” Tirek commented, seeing Cerberus’ knot bulge as it beat against Cozy’s flank. “That’s going to hurt.”
Cozy had no time to even think as she felt the knot smack harder and harder. The dog forced his cock deeper and deeper, forcing his knot into her hole. She screamed, the pain was unbearable, more so than before as a knot the size of her head was beating into her ass. Pulling back, almost as if he was going to pull his cock fully out, Cerberus then forced everything; knot and all of his massive cock into her ass. The moment he was fully inside the filly, his huge balls tightened, releasing his full load of cum.
Cozy’s body swelled instantly. Her belly painfully expanded as the boiling hot spunk filled her anal cavity; the thick knot making it impossible to leak out. But the force of orgasm was too much to hold in her body. She tried to hold it in, but she felt the burning fluid course through her insides, coming out of her mouth. She gagged, vomiting up the strong smelling, thick and seemingly endless stream of dog spunk. Cerberus continued to thrust, despite having his knot cork the filly’s insides. It rubbed in and out of her ass, continuing to thrust and cum for nearly an hour before the knot loosened enough to pull out; cum spilled out from the sudden opening. Cozy felt like she was about to die, chocking on cum.
“Fun fact.” Tirek laughed, savoring the sight. “You can’t die here. Which means, he’ll just rape you again, and again, and again.” Cozy’s eyes showed a primal fear over the torture she was going to endure for the rest of eternity. “Welcome to Tartarus.”
