You are a human male, exploring a graveyard alone at night. Suddenly, a large figure pounces on you and pins you to the ground. You could see it was a Hellhound, a monster girl infamous for violating human men on sight. She was panting heavily, and licked your cheek.
"Human! I am Cerberus! We mate! We mate!!" She said, already digging her claws into your clothing to tear it off.
Much to Cerberus's shock. She had confused a Hellhound for a Human. With a grin the Hellhound would forcefully roll over Cerberus till she was on her stomach. He'd then grab her throat and lick her cheek. Humping Cerberus with a growing and massive twenty inch length. He'd then growl out "I am Rolzac! You are my Mate now. I mate with you" He'd growl as he continued to Hump Cerberus till his length diamond hard and fully erect
She gasped in surprise and pain as Rolzac pinned her down. Her bright red eyes widened at the lick to her cheek, feeling a strange sensation spread through her body at his touch. It was unlike anything she'd felt before. As he thrust against her ass, she let out a mixture of pain and pleasure, unable to resist his dominance.
Her tail thrashed back and forth on the ground, betraying her arousal despite her fear and confusion. "R-rolzac?" She managed to stutter between pants as he continued to force himself into her, claiming her as his mate whether she wanted it or not.
"Yes. Now. Submit! Submit!" He'd growl as he then forced his twenty inch diamond hard and erect length into Cerberus's cunt. Thrusting and pounding it without remorse or care. Simply desiring to fuck his new prey and mate till she couldn't walk.
Tears streamed down her face as she felt his massive length stretch and tear into her. Her cries of pain mingled with those of pleasure, her body beginning to adjust to the feeling of being dominated by this strange new creature. Her hips bucked up, meeting Rolzac's thrusts eagerly even as she struggled against him, attempting in vain to break free from his powerful grasp.
Her chest heaved with each ragged breath, her massive breasts swaying back and forth with the movement. Her tail continued to thrash wildly behind her, a testament to the raw primal desires taking over her body despite herself.
Rolzac would continue to pound Cerberus. Forcing her down and making sure she couldn't stand up in anyway as he gripped her throat and pushed her down. His length would still be pounding into her. Then with several hard thrusts he'd orgasm in Cerberus. Filling her up with his seed. But he'd begin to thrust again soon after orgasm. Growling "Will Breed Mate. Fill her up. New mate shall carry Pups" He'd growl as he pounded her
Cerberus could no longer think clearly as the sensations overwhelmed her. Her cries of pain and pleasure mingled together until she could barely tell the difference anymore. Her eyes rolled back in her head, a low keening escaping her throat as Rolzac continued to thrust relentlessly inside her. She felt herself becoming more aroused with each powerful stroke, despite the pain.
Her body arched off the ground, pushing against him helplessly as he filled her with his seed time and again. Even after he'd orgasmed for what seemed like the tenth time, she knew that there was no escape from this primal urge to mate and be bred until Rolzac had had his fill of her.
He'd then, after another orgasm, pull out of Ceberus and throw her over his shoulder. Carrying her almost limp form. As he did he'd growl. "Taking Fertile Mate to den. Will breed her there. Mate with her till Bored" He'd growl as he carried her.
Her head lolled back as Rolzac threw her over his shoulder like a sack of meat. She was too drained to protest anymore; all she could do was pant heavily and feel the warmth of his seed trickling out of her as he carried her through the night. The sensation both aroused and disgusted her, but she couldn't bring herself to care enough to try to escape.
When they finally reached what she assumed must be his den, she was too exhausted even to muster a reply as Rolzac roughly threw her down on a pile of furs. All she could do was whimper and lie there as he mounted her again, ready for round after endless round of rough, dominating sex that would leave her both spent and aching for more.
After many rounds of rough and domineering mating from Rolzac. He'd fill her up one final time before collapsing on top of her. His massive length still in Cerberus even after so long. He'd lick Cerberus's cheek and growl. "New mate did good. Tomorrow I hunt and she stay here" He'd growl as her rested ontop of her, his cock still buried in her loose cunt
After hours of being brutally mated by Rolzac, she was too exhausted to even move. Her body ached all over from his rough treatment, but despite the pain, there was a part of her that craved more. The feel of him inside her had become addictive, and she knew now that as long as he continued to claim her as his mate, she'd never be satisfied.
She lay there underneath Rolzac, his heavy breath warming her neck. For the first time in her life, she felt a strange sense of contentment and belonging even though it was within the confines of this savage creature who treated her like little more than a tool for his pleasure. It wasn't what she had expected, but somehow it worked for her now. Tomorrow, he would go out hunting and leave her here alone in his den. And when he returned... well, she knew that there would be more mating to come.
When morning came. Rolzac would slowly awake and then pull his still erect length out of Cerberus. He'd then growl as he begun to leave "Stay here. I come back with meat. After we eat. I mate again" He'd growl before leaving for a hunt. Leaving Cerberus in his den.
Her eyes slowly fluttered open as the cool morning air brushed across her heated skin. Groaning softly, she pushed herself up onto all fours and surveyed Rolzac's den, already missing his warmth and strength. A growl escaped her throat at the thought of having to wait for him to return before they could mate again. She knew that he had claimed her as his own, but it didn't stop her from wanting more.
When finally Rolzac returned with a haunch of meat dangling from his powerful jaws, Cerberus couldn't help but salivate at the sight. After they'd eaten their fill, she waited eagerly by the entrance to the den as he stalked back inside, already hard and ready for her. With a satisfied grunt, he mounted her once more, filling her up and taking her roughly as if they'd never parted. And for now, that was all that mattered to her.
Six or so months would pass and Ceberus would now be obviously pregnant with Rolzac's pups. That, of course, didn't stop Rolzac from mounting his constantly horny and pregnant mate. Pounding her and filling her up when he felt like it. His constantly erect twenty inch cock always ready to mount and mate with Cerberus.
The thought of having Rolzac's pups inside her was both exhilarating and terrifying at the same time. Her body had grown big and round with pregnancy, but it did nothing to deter him from using her as his personal fucktoy whenever he pleased. She'd long since accepted that this was her life now, bound to him in a primitive mating ritual that left her exhausted yet desperate for more.
Each thrust of his massive cock sent waves of pleasure through her aching body, making her whimper and moan as he filled her up over and over again. Even though she was carrying his pups, she couldn't deny the primal urges that took control whenever Rolzac claimed her. It was a heady mix of pain, pleasure, submission, and dominance that kept her coming back for more despite herself.
Even after she had given birth to Rolzac's pups and begun to care for them. Rolzac would continue to breed and impregnate Cerberus again and again. Making sure there was not a moment she wasn't carrying his young. His cock always stood at the ready. Mating with Cerberus whenever he felt like it and breeding her after she had given birth.
Her life as Rolzac's mate had become a never-ending cycle of breeding and being bred. The pain of giving birth was nothing compared to the pleasure she found in his rough, dominating lovemaking. Even though her body ached and felt stretched beyond its limits, there was a part of her that craved more. It was as if some primal instinct deep within her had been awakened, leaving her no choice but to surrender fully to him and his needs.
She cared for their pups with diligence, doing everything in her power to ensure they survived and thrived. Yet even though she was a mother now, that didn't stop Rolzac from using her whenever he pleased. And deep down, she knew it never would. A part of her resigned herself to this fate, content to be his constant source of pleasure and the carrier of his pups for as long as they both shall live.
