A/N: Hello there! This is only my second Hellsing fic. This idea has been in my head for days, and it just wouldn't go away. So I wrote it down.

This story is rated M for a reason. It has sex, crude language, seduction, violence, all of that. If you aren't comfortable with explicit sex scenes, turn back now.

That being said, I hope everyone enjoys, and I would love to hear what you think. Please review. You have no idea how happy reviews make me. I love hearing what people think.

PROLOGUE

UNIQUE

The study was spotless, almost shining, as Arthur Hellsing sat at his desk, a half-empty bottle hanging limply between his fingers. He stared at the door with unsteady eyes, his blonde hair dishevelled as if he'd just woken up. He had long discarded his jacket and had undone the first few buttons of his wrinkled shirt. "Walter!" he yelled.

The study door creaked open, the twenty-five year old butler quietly slipping inside the large room. "Yes Sir Hellsing?"

"Is she here yet?" he asked, voice hoarse with drunkenness.

Walter raised a brow, "I beg your pardon, Sir?" he questioned. Are we having a guest? Did I forget?

Arthur ran a hand through his unkempt hair. "That girl I hired...is she here?"

Still confused, Walter simply took his employer's jacket from where it was draped over the couch and folded it. "May I ask who you're talking about, Sir?"

Growing frustrated, the Hellsing commander slammed his fist onto the table. "The whore," he slurred. "The one with the short brown hair."

"Miss Rachel?"

Arthur nodded, rubbing his temples. "Yeah, her."

Walter fought the smirk that threatened to show as he busied himself with cleaning up the empty bottles strewn around the study. "I see."

Excusing himself, the butler left his employer alone and turned his attention to the circular hallway mirror. Slicking back his hair and smoothing down his vest, Walter let the mischievous grin spread across his face.

Arthur Hellsing had many bad habits, a liking for alcohol and prostitutes were only some. The man often combined the two, getting incredibly drunk before having his way with whatever woman he'd hired. However, that often resulted in the woman remaining unsatisfied from the apparently sloppy, unexciting sex (he had overheard many complaints).

Therefore, on those nights that Arthur Hellsing would hire a prostitute, Walter would make himself scarce to avoid awkwardly having to speak to an angry, scantily dressed woman storming out of the manor in the middle of the night.

But with Emmaline Rachel, it was different.

For starters, she wasn't even human. She was a succubus, hundreds of years old. Secondly, despite the lack of pleasure she got from Arthur she still came when he hired her...but for a different reason.

He still wasn't sure how it had happened. He had first seen her the year before, ready to leave the manor early in the morning, and he had offered her a drink. Banter and wine by the fireplace had turned into making out on the couch like teenagers... then that had turned into taking her to his room and ravishing her.

Ever since then, whenever Arthur would hire Emmaline, Walter definitely had a reason to stay in the manor.

The doorbell chimed loudly, echoing through the manor.

Taking a moment to compose himself, Walter walked to the doors and opened them, standing aside to allow the visitor in. He could barely keep an indifferent, professional expression. "Miss Rachel, how lovely to see you here again."

A low, sultry voice with a faint American accent answered. He could hear the teasing tone as she asked, "I'm sorry, what was your name again?"

Walter chuckled, his eyes wandering across her body lustfully. Her heart-shaped face was soft, her tempting lips painted with pink lipstick. Her dark golden eyes were framed with thick black lashes, her dark hair reaching her jaw in a stylish bob. The black dress hugged her hourglass body, ending just above her knees. Grey stockings encased her legs, her high heels making it so he could look her in the eyes without having to bend his head.

Walking beside her to the study, Walter politely opened the door for her. "Here you are, Miss." As he watched her walk in, he murmured so only she could hear. "Meet me in the sitting room once he let's you go. I'll be waiting."

OOO

Walter glanced at the clock when he felt dainty hands on his broad shoulders. "You're very early," he commented, capturing her hands to kiss them.

Emmaline smiled, pulling away only to walk around the couch and sit on his lap. "Sir Hellsing fell asleep before we both even got naked," she explained. She draped her arms around his shoulders, showing two sets of sharp fangs as she grinned.

Walter smirked, placing hot kisses from her jaw to the hollow of her throat. "Oh really now?" he purred, his smooth voice causing a bolt of arousal to shoot down her spine. "Well what a shame..." his fingers trailed down her bare arm. "I can't just let a lady leave unsatisfied."

Emmaline let a whimper of pleasure escape her, "I-I need..."

Walter grinned against her soft skin. "What do you need?" he murmured. His hand slid down her stomach and under her dress, cupping her hot pussy through the cloth of her panties. "You're already drenched," he growled.

Her hips rose instinctively, her clit pressing into his palm. "Oh God...Walter," she breathed.

His other hand rested on her back, slowly undoing the laces of her dress. Sliding her dress off her body until it pooled onto the floor, he brought his lips to her ear, nibbling lightly on the sensitive flesh. "What a bad girl you are, shagging the butler when you're payed to please Sir Hellsing." The hand on her back moved to her firm behind, squeezing the skin hard. "Oh yes, you're a very bad girl."

Emmaline licked her rapidly drying lips. "I-I'm surprised you're not running in fear. I'm a succubus, after all," she teased. She gasped as she suddenly felt thin wires shred her panties.

Walter chuckled darkly, whispering in her ear. "Relax my little sweet tart, you know my wires won't hurt...unless you want them to."

Emmaline felt her heart race. 'Sweet tart' was the nickname Walter had given her in their first time together, after remarking how she was similar to a tasty dessert - something that he planned on thoroughly savouring.

He only ever called her 'sweet tart' when he was planning to be rough.

She was broken from her thoughts when the butler bit down hard on her ear, slamming two fingers inside her without warning. She cried out, arching her back. Walter placed his free hand on the back of her head, grabbing her hair. He growled, pressing a bruising kiss to her full lips.

Feeling the butler's tongue caress her lips she opened her mouth, letting their tongues slide together in a passionate, heated kiss. His fingers suddenly withdrew from her.

Hearing the succubus whimper with need, Walter broke the kiss. "Easy there," he purred, undoing his belt and trousers with one hand. "We're nowhere near done, baby." He gently pushed her down onto the couch so she landed on her back, then straddled her, one hand on the armrest above her head and the other resting on the small of her back.

Emmaline gasped in pleasure when the butler thrust inside her. "Fuck," she panted.

Walter kissed her again, biting her lower lip hard enough to draw a small line of blood. He groaned, quickening his pace. The succubus beneath him moaned in lust, her sounds muffled by his kiss.

He released her lips slowly, moving to kiss down her neck to her shoulder. "Damn baby," he growled. "You feel so fucking good."

Emmaline slammed her eyes shut, gritting her teeth from the rising pleasure. Her stomach tightened. "Walter," she whispered. "Walter...make me cum."

He flicked his tongue over her right nipple. "Ask nicely, sweet tart," he purred, his eyes dark with lust.

Somehow, her sex-clouded mind managed to remember what he wanted to hear. "Please may I cum?"

The hand on the armrest moved to her throat, wrapping around it ever so slightly. His smooth voice now back near her ear, he growled. "That's a good little succubus. Now cum. Give it to me."

She did on a scream, slamming her eyes shut as the pleasure finally peaked.

Letting go of her throat, Walter panted heavily as he pounded in and out of her, chasing his own orgasam. He felt it building, and rested his head in the crook of the demon female's shoulder, letting out a muffled yell as he released inside her.

They lay there for a few moments in silence, before Emmaline spoke. "I have to go."

Walter gripped her hips tightly, "No bloody way," he murmured. Despite this, he retracted his wires from her wrists, freeing them.

She smirked, "I can't just stay here. The others I'm living with hate the Hellsing family. They don't even want me within ten feet of this place. Besides, even if I could stay, Arthur would kill you if he figured out why I was still here when morning comes tomorrow."

Walter laughed, mischief gleaming in his eyes. "He'll have such a hangover tomorrow that he won't notice a thing," he pointed out. He kissed the hollow of her throat, "If you stay," he murmured. "You'll get a good fucking in the morning. I'll make you cum so hard you'll see stars, sweet tart."

Emmaline moaned softly. The idea of such a promise awaiting her when she woke was legitimately tempting. But she shook her head, wriggling out from underneath him. He may not have been overly muscular and bulky, but he was surprisingly heavy.

Sitting up to allow her to move, Walter sighed. "Alright, I get the picture." He watched her stand and redress, before grabbing her torn panties and stuffing them into her purse. He raised a brow, "Hope you didn't like those, by the way."

She shrugged, "I did, but they can be replaced." She glanced at him, "It's a work hazard," she answered cheekily.

He smirked, doing up his trousers and picking up and buckling his belt. "If Sir Hellsing asks, I'll lie and tell him you're looking forward to coming back."

"Oh but I am," she replied, dragging a hand down his strong chest. "Just not because of him."

Walter grasped her wrists, placing a kiss on each of her fingers. "You're very deceitful, little succubus. Maybe next time I'll give you a spanking," he growled.

Emmaline swallowed in excitement at the suggestion. "I'll make sure to really misbehave then, Angel of Death."

Walter sucked in a deep breath. She knew how hard he got when she called him by his title. "You'd better get going right now, or I might just keep you here."

She blew him a kiss, before quietly leaving the sitting room, shutting the door behind her.
