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.

The hellhound ignored your protests and bit down on one of your nipples, rolling her tongue around it and sucking hard as she released a moan into your chest. Her hips moved rhythmically against yours as she ground her sex against your groin, clearly aroused by the scent of you.

The hellhound grinned wickedly at your squirming. Her other paw reached down to grasp your throbbing cock through your pants, stroking it firmly as she continued her assault on your body. You could feel yourself growing harder under her touch, despite the pain and fear coursing through you.

"Let Cerberus mate with human! Make babies!" She growled lustfully into your ear, her hot breath sending a shiver down your spine.

The hellhound's eyes narrowed and her nostrils flared as she smelled your fear, the scent only serving to further excite her. With a growl, she bit down harder on your nipple and thrust against you even harder. "No stopping! Must mate now!" She groaned out through clenched teeth, her hips bucking up into your crotch rhythmically as she desperately sought release.

Her grip on your nipple tightened further as you cried out in pain, her panting growing more frantic at the sound. Her movements became even wilder, her hips thrusting against yours harder than ever before as she ground herself against you with desperation. "Cum for Cerberus!" She demanded, lips curling back in a savage grin as her tongue flicked out to lick your chest where it was reddened by her teeth.

The sensation of her hot, wet body impaling itself upon you was exquisite agony, sending waves of pleasure-pain coursing through your entire body. She continued to ride you hard and fast, using her powerful hips to drive deeper into you with each thrust as she grunted and growled like an animal in heat. Her nails dug painfully into your shoulders as she held on tightly for support while she lost control to the insatiable need consuming her.

She growled as you tightened your grip around her waist and thrust against her in return, pleasure coursing through her body at the realization that she had finally overcome you. "Cum for Cerberus!" She demanded once more, determined to feel every drop of your seed spilling into her.

Her movements grew even wilder as she rode you relentlessly, the pleasure building inside her until it felt like her entire body was going to explode from the sensation. Finally, with a loud, feral cry, Cerberus came hard, her body tense and shuddering as wave after wave of ecstasy washed over her, filling her up with your warm seed. She collapsed on top of you, panting heavily, their sweaty bodies pressed tightly together in the cool night air.

She stayed on top of you for several long moments, catching her breath before finally pushing herself up to hover over your still-throbbing cock. "Better?" She purred, glancing down at you through her lashes before looking away again and giving a little shake of her head.

"No more hurting humans... I promise..." Her voice trailed off uncertainly as she lowered herself back onto your length. "Unless you want me to..." She muttered, hips moving on their own now as the pleasure coursed through her once more.

Her ears flattened against her head in shame as she slowly shook it side to side again. "Yes... no more hurting humans..." She repeated, voice more firm now. "Cerberus promises..." Another deep breath before she lowered herself back down onto your cock, letting out a satisfied moan at the feeling of you filling her up once more. "See?" She mumbled as her hips started moving faster again, body beginning to enjoy itself all over again. "I'm good now."

The monster girl bit her bottom lip and nodded slowly as she continued to ride you. "See?" She repeated, the word losing its meaning but gaining sincerity instead. "I'm good... I promise..." Her voice trailed off again, this time sounding more certain than before. As she moved against your length, her movements grew more gentle and affectionate. It almost felt as if she were trying to make up for the violence of their earlier encounter by being extra careful now.

Her breath came faster and heavier with each thrust, and her reddened eyes closed tightly in pleasure as you filled her completely. She gripped your shoulders tightly, her fingernails digging painfully into your flesh, but the discomfort was far outweighed by the bliss coursing through her. "Faster?" She murmured, opening one eye to look down at you. "Want me faster?"

The hellhound nodded and obeyed, picking up her pace even further as she lowered her head to nuzzle against your neck. Her tongue flicked out, teasing the sensitive skin just under your earlobe before lapping at it hungrily, her hot breath sending shivers down your spine. "That's a good human..." She murmured, sounding far more like an affectionate lover than a monster on the hunt.

Her hips bucked up into yours harder now, her body moving in perfect syncopation with the powerful thrusts of your cock. Her moans grew louder as she neared her peak once again, and she arched her back off the ground slightly, giving you an unobstructed view of her tight, heaving breasts. With a final, desperate cry of pleasure, Cerberus came again, her body shuddering against yours

The pleasure was so intense it felt like her entire body was being torn apart. She screamed and convulsed on top of you as wave after wave of ecstasy washed over her, and finally she collapsed limply onto your chest, panting heavily, her huge breasts heaving against your bare skin. Her face flushed a deeper red from exertion, making her already fiery eyes stand out even more.

"Tired now..." She managed to get out between ragged breaths. "Rest..." It was a command disguised as a request, but she didn't seem to care. For now, she needed rest and recuperation before she could hunt again. And you... you were hers for the taking. She smiled fondly down at you, running her fingers through your sweat-soaked hair before closing her eyes, finally allowing herself a moment of peace after such an exhausting encounter.

She let out a low growl and tried to push you away, but her strength was all gone now. "No... not home..." she mumbled, sounding irritated. "Not human home... my den." Her eyes opened slowly, fixing on yours with a strange mix of affection and determination. "We go to my den, okay?"

With you carrying her in your arms, the monster girl led the way through the graveyard and into a dark, overgrown part of the woods beyond. Her den was just large enough for them to fit comfortably inside; it had been well hidden from prying human eyes by an elaborate network of roots and branches. Once they were inside, she shifted back into her animalistic form - black fur covering her body as her tail began to twitch excitedly behind her. She curled up next to you on the soft bed of leaves, nestling herself against your chest with a contented sigh.

"Good human..." She murmured, already starting to drift off to sleep. "Love Cerberus... want Cerberus... be with Cerberus..." Her voice trailed off into silence as her eyelids grew heavy and she finally succumbed to the sweet release of slumber. As the hours passed, her breath

Her body relaxed further into yours as she slept, her heart racing slowly beneath your palm where it rested against her chest. The soft rumble of her snores filled the air around them, and every now and then her tail would give a flick or a thump against the ground as if in delight at being close to you. In her dreams, she was running free through endless forests, her red fur gleaming in the moonlight as she chased down prey with unnatural grace. But always, somehow, she found her way back to you... curled up against your warmth, safe from harm and cherished beyond measure.

The next morning found the both of them still cuddled up together in their little nest. The monster girl's eyes opened lazily, taking in the dim light filtering through the leaves overhead as she stretched languidly, yawning contentedly. Her sharp claws unsheathed briefly before retracting again, the sound making soft clicking noises against her fingers that sent shivers down your spine. She nipped at your neck gently, a silent greeting, and soon afterward sat up on her haunches, gazing down at you with an unreadable expression in those fiery red eyes of hers.

"Hungry?" She asked quietly, her voice still rough from sleep. "Want food?" Her tail wagged slightly behind her, the movement seeming almost canine.

She nodded and padded over to the entrance of the den, peering out cautiously before disappearing into the underbrush. You could hear rustling noises for a moment before she returned with a rabbit dangling limply from her jaws; it was barely more than a mouthful for her but would be enough to sate your hunger until nightfall. The monster girl carefully cleaned the little creature, then tossed you the still-warm carcass before settling back down next to you, waiting patiently for her own share.

She narrowed her eyes slightly as you reached to give the rabbit to her. Her head cocked to the side and she sniffed at you, almost like a curious dog. "Don't want..." She said slowly, her voice barely above a whisper. "Share..." Her tone left no room for argument.

With that, she nudged your hand away from the rabbit and took hold of it with her claws once more, tearing off a piece of meat and offering it to you. Her eyes never left yours as she did so, her body tense and ready to pounce if you made any sudden movements. It seemed that sharing wasn't something she was used to doing willingly... or safely.
