Some hellhounds devoured souls and dragged people to Hell, but that was never your role. As a demi-human, you understood a little more than the others, which allowed you to take on a different job: guarding.

At first, your assignments were simple. You guarded torture chambers or the cells of more troublesome souls who couldn’t be left unattended.

It was simple—if anyone tried to escape, you barked or snarled. If someone had already escaped, you bit them.

That much your brain, which was more animal than human, could understand.

The problem arose when your abilities were finally recognized and you were assigned to a far more difficult task: guarding the cage that held Lucifer himself.

Since you rarely spoke and your responses were usually limited to a word or two, no one believed Lucifer would be able to influence you in any meaningful way.

That assumption turned out to be a huge mistake.

The first few days passed quickly, though not without problems. As soon as you were let inside and stood before the cage, Lucifer smiled to himself.

“Well, hello there,” he murmured.

You weren’t used to this—to being spoken to. Slowly, you lowered yourself to the ground and sat cross-legged in front of the cage, staring at him intently.

“Hi,” came your response after a beat.

Lucifer’s smile only widened.

“I’ve got a little puppy guard. Who would’ve thought?” he hummed with amusement, shaking his head before stepping closer to the bars and crouching in front of you.

“Do you do tricks, little one?” he joked lightly, reaching out to touch you.

You immediately flinched and bared your teeth, a low growl rumbling in your throat at the gesture. Your tail twitched as well, making it clear you weren’t particularly fond of being touched.

Lucifer withdrew his hand, but his smile never disappeared.

“Not a fan of petting, hm?” he murmured, leaning back.

Over the next few days, Lucifer tried to tame you in a way. He talked to you, getting you used to the sound of his voice. He encouraged you to come closer, and even though you bit him a few times, he never got angry or hit you. He simply backed away.

The first time you finally allowed him to pet you, he smiled and ruffled your hair, murmuring, “Such a good puppy,” over and over again.

Your tail gave a single pleased twitch when he rubbed that perfect spot behind your ear, and another when he quietly whispered, “Good boy.”

He earned your trust because he never pressured you. He was patient. Attentive.

Before long, Lucifer became the only person you truly listened to. The demons of Hell rarely treated you with kindness, while Lucifer remained consistently gentle. That gentleness was unfamiliar—almost addictive—and, unfortunately, you found yourself craving his attention more and more with each passing day.

The next time you were on shift, guarding his cage while curled up on the floor, Lucifer wandered over to the bars and crouched down to your level.

You looked so vulnerable. So pretty. Far too comfortable around the literal Devil.

Lucifer’s gaze drifted over the curve of your back before settling on your tail, tucked beneath your chin. Something in his expression shifted ever so slightly.

Curiosity, laced with desire.

He wasn’t stupid, though. He couldn’t simply grab you and force you into anything. That would shatter the trust he’d worked so hard to build. Instead, he chose a different approach.

You couldn’t see him snap his fingers, but your head lifted at the sudden, unfamiliar warmth that began spreading through your abdomen. Your ears flattened, and your tail gave one confused thump against the floor.

Lucifer watched intently as you curled in on yourself, your face flushed, one hand pressed over your stomach.

“You’re looking distressed,” he observed, even though he knew exactly why. “What’s wrong, puppy?”

“Feels… warm,” you mumbled, your fingers twitching restlessly where they clutched the fabric of your shirt.

“Where?” Lucifer asked gently, his eyes dropping to the twitching tip of your tail, now tucked firmly between your legs.

“My… belly,” you answered quietly.

You could feel the unfamiliar warmth traveling lower, settling somewhere between your thighs. Involuntarily, your hips rolled forward, searching for a kind of relief you couldn’t understand.

“It’s…” You tried to explain the sensation to Lucifer, but failed. Your hips jerked forward again, a little more sharply this time.

“It’s okay, pup,” he murmured, patting his thigh lightly. “I can help you.”

You looked up at him, still rooted to your spot on the floor.

“But…” The protest dissolved into a soft whimper.

The sound surprised even you. Your ears flattened further, pinning themselves so tightly against your head that they nearly disappeared beneath your hair.

“Shh…” Lucifer cooed, patting his thigh once more. “I know what you need. You just have to trust me.”

The softness of his voice made you want to believe him, especially in such a vulnerable moment.

Slowly, you pushed yourself upright and crawled toward the bars. Lucifer’s hand immediately found your hair, long fingers slipping through it as he brushed a few sweat-damp strands away from your face.

“Look at me, puppy,” he whispered, gently cupping your cheek. “I need you to come in here so I can take care of you.”

Your vision had begun to blur around the edges. Everything felt hazy, making it difficult to fully process what he was saying. The strange sensation only continued to grow, leaving you restless and desperate for relief.

You forced yourself forward, squeezing carefully between the bars. By the time you made it through, you were standing directly in front of Lucifer.

He smiled and slipped an arm around your waist. That simple touch made you squirm.

“Look at you…” He murmured, drawing you onto his lap. “My poor little hound…”

Your head fell forward helplessly until it rested against his chest.

"I need..." you whined, and your hips rolled forward again, this time right over Lucifer's thigh.

He didn't push you away—quite the opposite—his fingers clasped around your waist, slowly guiding the restless movement.

"It's alright, I know what you need..." Lucifer's lips pressed briefly to the top of your head before his hand traveled lower to your hip.

You continued rutting against his leg, desperate to create any kind of friction, even though you were already soaking through your panties and leaking onto the fabric of Lucifer's jeans. He didn't seem to mind at all.

"Such a good, needy boy," he praised while rubbing slow circles over your waist with his thumb when you started squirming and whimpering in his lap.

Your tail twitched with every push of your hips forward and your quiet whimpers filled the air.

"Please..." you whined weakly, looking up at him through half-lidded eyes. You weren't even sure what you were asking for.

"What is it?" He pressed, despite the fact that he literally did this to you. "Does my puppy feel empty?"

You nodded your head frantically in response, still rutting desperately forward and panting quietly.

One corner of Lucifer's lips rose and he shifted his grip from your hip to the curve of your ass. He pulled you flush against his chest before letting his hand wander lower.

You didn't even notice when your pants were off, Lucifer made them disappear too suddenly, leaving you exposed and trembling in his lap.

Then, he freed his cock from his underwear, shifting his grip on you so he could position himself better. Your head finally moved up.

"I... what—" your movements stuttered and you glanced down at his length now pressing against your entrance.

"Shh, it's okay. Just relax," Lucifer whispered against your neck, pushing past the entrance and slowly slipping inside. You were already so wet that prep wasn't needed at all.

You moaned at the intrusion, hands moving to grip his shoulders tightly when he started pushing inch after inch of his cock into your throbbing hole. Your tail twitched, curling around his leg as if to hold onto something.

"So tight," "you're perfect," "my good boy," Lucifer kept praising while thrusting inside.

He fucked you gentle and deep, making sure to slow down whenever you were too close to reaching release. The edging left you even more restless, hips snapping forward to meet every single one of his thrusts.

At some point, you bit down on his shoulder, unable to take the tension anymore. A quiet groan left Lucifer's mouth and his hands snapped to your hips, pulling you down onto his cock in one, sharp movement.

He came inside you letting out a low sound of satisfaction and filling you up. The sensation of his cum flooding your insides made you clench around his length and come with a broken moan.

Your teeth sank deeper into his shoulder from the overwhelming wave of pleasure that washed over you.

"You did wonderful," Lucifer cooed, not pulling out just yet, "took my cock so good..."

You whined, curling into his chest and still leaking onto his lap. Yet, you felt satisfied like never before.

Lucifer kept you close, giving your forehead a brief kiss before pulling you flush against him.
