Sealing the Pact

"Of course not. What use would I have for your blood?"

"Then, what do we need to exchange?"

The devil tilted his head to the side in amusement. "Every demon has a different preference. I'm sure you know mine."

Cecilia didn't. She stared blankly, mouth open as she tried to work out what he meant. The devil only smiled.

"Come on, you must know who I am, surely? You've read my book, after all" The demon extended a clawed finger towards the reading table, where Cecilia had left her book open earlier that day. The book she loved so well. 'Tales of the Incubi'.

"Y-You're...?"

"Amalicath Kirkoron, yes. The titular Incubus. It's always nice to meet a fan." The demon chuckled.

Cecilia felt a sudden wave of excitement rush through her. She knew exactly what the demon wanted from her, and she was more than happy to oblige. After all, how many nights had she spent imagining herself in place of the book's protagonist, giving in to all the depraved requests of the incubus, pleasuring herself long into the night while she picturing him taking her in all manner of devilish ways? She felt her heart tremble.

And to be honest, it sounded a lot more fun than the eternal torment most demon's asked for.

"Well?"

Cecilia swallowed hard. She'd never actually been with someone before, locked up in the manor, but that didn't stop her.

"I... Yes. I know what you want. And I'm ready."

The demon smiled. "Good. Now, come here."

Her heart aflutter with anticipation, Cecilia took a step towards the demon, acutely aware of his shirtless torso, his abdominal muscles hard as rocks. His legs were covered by a pair of tight leather trousers, but through the fabric she could already see the quickly forming outline of a very impressive bulge. His eyes stared at her hungrily, and his hand toyed with the buckle above his crotch.

When she was within a yard of him, he reached out a hand, offering it to Cecilia. She accepted, and he drew her in closer, wrapping an arm around her. She put out her hands, making contact with his chest. She began to run them up and down his torso, admiring the infernal heat radiating out through his smooth red skin. She looked up at him, towering above her, almost two feet taller than her.

Amalicath flashed a wicked smile back down at her.

Cecilia's mind was awash with emotions. Was this really happening? Was she really about to make love to a demon? She tapped her hands on his chest, just to make sure he was really there. The devil chuckled. She felt his hand moving up her back, the sharp claws on the ends of his fingers tracing up her spine, sharp even through the fabric of her dress. A shiver of pleasure rippled through her, and she let out a quiet, involuntary gasp. Oh god. She didn't care if this was real, she wanted it so badly.

Amalicath's hand continued up her body, fingers raking across the back of her neck, making her body quiver, before coming to a rest on top of her head. Gently, but with enough force to make his intention clear, he pushed down.

"Kneel."

Without a word, Cecilia did as he commanded, her mind and body both burning in anticipation. Kneeling down before the demon, her head hovered just in front of his groin, barely inches from the massive bulge in his trousers. She put her hands on her knees, looking up, awaiting instruction.

The devil's smile widened, showing off a pair of sharp canines. With ease, he undid the buckle of his leather trousers, letting them fall to the ground as his erection stood to attention. Cecilia gasped.

It was huge! Close to seven and a half inches at least, if not more. The dark red of the demon's skin continued down to his crotch, his cock the same hue as the rest of him. As she stared at it, eyes wide, she watched the head bob and twitch with anticipation. There was no way she could take the whole thing into her mouth, not to mention her virgin pussy. This was going to be more of a challenge than she'd expected.

After a moment of silence, enjoying the young woman's reaction to his infernal member, Amilicath gave her head a tap of encouragement. "Not having second thoughts are you?"

Cecilia looked up at him, and shook her head, a mischievous smile forming on her lips.

"Good. Then open your mouth, little mortal."

Cecilia did as she was told, opening her mouth as wide as she could. Steadying herself, looking up for approval, she leant forward, resting one hand on the demon's thigh, the other curling around the base of his cock. She could hear her heartbeat pounding in her ears, a mixture of apprehension and excitement mingling in her stomach.

As she took the head of the demon's cock into her mouth, Amalicath let out a long contented groan. His hand moved from her head as she relaxed her jaw, letting her lips close around his member. She took a moment to adjust, still getting used to the feeling of a cock in her mouth for the first time, before tentatively running her tongue across the tip. The devil's cock was hot, a lot hotter than she'd expected, and as she explored his shape, Cecilia found herself becoming intoxicated by the taste.

Getting bolder, she decided to try and start moving. Pushing her head forward a bit more, she began to slowly bob backwards and forward, enjoying the sensation of the demon's cock sliding in and out of her mouth. Soon enough, she had him moaning as she worked him back and forth, taking almost half of his cock each time.

Cecilia felt amazing. Even though she was still a little nervous, she settled into a rhythm quickly, enjoying being on her knees before the creature, making him groan as she gave him head. It made her feel sexy, like some king's prized concubine, pleasuring him as he stood before her. Under her dress, she could feel herself getting wet.

Happily in the flow, Cecilia suddenly felt Amalicath's hand on her head again, his grip firmer this time, his fingers curling into her hair. Holding her in his grip, he began to guide her head back and forth along his cock, encouraging her to take him deeper with each thrust. Soon Cecilia had both hands on the demon's thighs, steadying herself as she let her new demonic patron take control, forcing her mouth down and across his thick cock in long, deep strokes.

Each time he thrust her head down, Cecilia let out a gulp as the tip of his cock pushed further into her mouth. She had never felt so alive. The demon standing in front of her didn't slow down, starting to thrust his hips in time with her head, and Cecilia felt a wave of excitement unlike anything she had ever felt before.

To be taken like this, give herself to someone in such a way, felt incredible. While her hands kept a firm grip on his legs, Cecilia's pussy ached for release, her juices soaking the black lace panties she'd put on in preparation. At the time it had just been for her own benefit, the knowledge that even under her gown she looked incredible, but now she knew Amalicath would see them too, she couldn't help but feel even more aroused.

As his thrusts came faster, Cecilia began to wonder how much longer it would be before he came, and as if on cue she heard his voice from above her.

"Get ready my little whore, I want you to swallow every drop!"

Cecilia felt a jolt of adrenaline. This was it. She was going to make him cum! She readied herself, forcing herself to go even faster as the demon's hand practically slammed her head up and down on the throbbing member in her mouth.

Starting to get more and more erratic, Amalicath kept thrusting into her mouth, the tip of his cock leaking precum, before letting out a roar. Cecilia squealed as she felt the first jet of his thick, infernal cum shoot out and coat her mouth, before another, and another. Before she knew it, her mouth was full of the salty-sweet liquid. She'd never tasted cum before, especially not a demon's, but as she felt it sliding down her throat, she decided she loved it. Gulping down happily, she managed to swallow his entire load, before her demon lord withdrew his cock from her lips, leaving her gasping for air as she tried to catch her breath after such an intense blowjob.

On her knees, with the infernal taste of cum still on her tongue, Cecilia couldn't help but feel a bit disappointed that the act had ended so soon. But as she looked back up, her eyes caught sight of Amalicath's cock in front of her, still just as hard as it had been before he filled her mouth.

"Oh, you didn't think that would be enough for me, did you?" The demon grinned. "We're just getting started."

With surprising ease, Amalicath pushed Cecilia Down, knocking her onto her back, before grabbing her legs and flipping her over onto her stomach. She felt his claws on her hips as he pulled her ass into the air, leaving her chest and arms on the cool floorboards of the library.

Looking over her shoulder, she saw him kneeling behind her, his burning cock held in his hand, as he inspected her wetness. She felt her nipples straining with arousal.

Laughing the demon ran a clawed finger up her thigh and across her buttock, hiking her dress up and over her waist while staring between her legs. "Lace down here as well. You knew this was going to happen, didn't you, my little slut?"

Cecilia felt herself blushing. Biting her lip, she said nothing, until her patron ran a finger across her privates, teasing her through the fabric. Letting out a high pitched moan, she shut her eyes, rocking her hips back involuntarily, her body desperate for the devil to take her virginity.

Amalicath let out a chuckle as he watched his new toy squirm. Running his fingers across the soft flesh of Cecilia's rear, he revelled in her moans, but soon decided it was time to move on. Reaching out, he slipped his fingers under the waistband of her panties, pulling them down agonisingly slowly. Cecilia let out a long mewl of frustration.

Her pussy now bare to the world, Cecilia felt her heart pounding even harder in her chest, her cheeks bright red as she tried to keep herself under control. All she could think about was the thick red cock behind her, the way it would feel sliding into her pure, untouched pussy, how amazing it would be to give herself to this creature of darkness, how much she longed to be his little whore.

Suddenly she let out a cry of pleasure, as she felt Amalicaths forked tongue run between the damp folds of her pussy. He didn't stop there, beginning to assault her aching cherry with his skilled mouth, flicking her clit and sucking her labia, causing her to squeal and writhe in pleasure. His hand kept her hips still, but that didn't stop her upper body squirming with delight, her mouth open and mewling.

All too soon he stopped, and Cecilia let out a groan of frustration, but before she could say anything she felt something hard press against her entrance. Something large and hot.

Looking back, she saw the devil, back on his knees, his clawed hands gripping her tight as he lined his infernal cock up with her virgin pussy. He grinned down at her, eyes burning with lust as he growled.

"Are you ready, little whore?"

He didn't wait for a response, instead rocking his hips forward, making Cecilia gasp. She barely had time to process what was happening before he was inside her, his throbbing member buried in her, taking her virginity with ease. She let out a long, low moan as she was penetrated for the first time, feeling her walls expanding to allow Amalicath's thick girth inside.

The demon cackled as he watched his latest conquest quivering on the ground before him. "Your first time, is it?" He lent forward, a wicked smile spread across his lips. "Don't worry, I'll make it memorable."

With that, he began to move his hips, slowly at first, but quickly picking up speed. Cecilia squealed as his hard cock plunged into her tight wetness, the feeling of his thick shaft almost more than she could bare. She never could have imagined how good it would feel, and as the demon pounded away at her she felt herself slipping into an almost primal lust.

Still sprawled on the floor, eyes hazy and mouth open, Cecilia moaned out in time with Amalicath's thrusts. Each one sent a new bolt of pleasure through her body, driving her wild and making her squeal as the demon took her. With a sudden crack she felt his hand come down on her exposed rear, smaking her buttock as he fucked her from behind. She let out a cry of pleasure, before falling back forward again.

As he continued to pound into her tight young hole, Cecilia couldn't believe she hadn't done this sooner. All those lonely nights alone, laying in bed with only her hands to please her, imagining this very situation while she fingered herself wildly. All that time she could have had exactly what she'd wanted.

Another crack echoed throughout the library as the demon spanked her again. The usually silent room had filled with the sounds of their rough fucking, the squeals and moans of Cecilia on her knees as her demonic lover pounded into her with loud slaps of skin on skin. Reaching out, Amalicath took a handful of Cecilia's hair, pulling her head up roughly as he made love to her freshly deflowered vagina.

"Abyss, you're tight" he growled, not slowing his pace at all. "What a privilege to be the first to defile you." With every word Cecilia felt a new shiver of excitement rush through her.

"I think this is going to be an excellent partnership. I'll have to visit you more often"

"Y.. Yes..." Cecilia managed to moan out between gasps. "I'll... summon you... every... night..." The demon laughed.

"Oh, don't worry about that. Now that we've made a deal, I can appear to you whenever I like."

With a grunt of exertion, the demon wrapped his arm around Cecilia's waist, pulling her upright until her feet left the ground. Holding her up with both arms, the devil began to fuck up into her, taking her while standing, his arms under hers.

"I'll come to you whenever I please, and take my fill of you." The new position felt even more amazing than the last, and Cecilia could barely think through the pleasure as Amalicath's cock pounded up into her, deeper than ever.

"You're going to make such an excellent little slave, aren't you, my pretty little slut?" Cecilia looked over her shoulder, hazy eyes half shut and desperate, lips parted as she gasped with each deep penetration.

"Yes... Master..."

The demon laughed. "Say it. Tell me what you are."

"I... I'm your... I'm your little slut, master... your little plaything t... to fuck whenever you want."

Amalicath smiled. "Good girl." Reaching around her, he wrapped his hand around her neck, not too tightly, but enough to drive the young woman wild. Cecilia had never felt so aroused, the demon holding her in his arms as he fucked her hard and fast. The hand around her throat only made her feel even more sultry, a reminder that she was his now, forever.

Deep in her stomach, she started to feel a familiar sensation, but not one she'd ever felt with another person before. Sensing her impending orgasm, the demon redoubled his efforts.

"Are you going to come, little whore?" Cecilia managed to nod weakly, eyes pleading with the infernal being holding her not to stop. "Good".

Moving his hand from around her throat, the demon began to play with Cecilia's clit, resting his hand against her pubic mound while he pleasured her both inside and out.

"I'm about to come to. I'm going to fill your little pussy full of it, and mark you as mine. You'll be my little slave, and in return, I'll grant you the power you seek." Cecilia felt her heart do a somersault.

Suddenly increasing his pace, Cecilia heard Amalicath groan with exertion as he pounded into her harder than ever before, his cock tearing into her snatch with such force and vigour she worried he might tear her apart. She felt her breathing starting to quicken, and her body beginning to spasm of its own accord, as a familiar burning feeling flooded her entire body. She was right on the edge, ready to come, when suddenly the demon pulled her hips down hard onto him, letting out an almighty roar of ecstasy.

As she felt the first hot spurt of infernal cum splash against her walls, Cecilia toppled over the edge, letting out a loud scream as her pussy contracted around the cock inside her. Her stomach clenched over and over, her whole body shook with the force of her orgasm, her nipples straining against the fabric of her dress as she came hard.

With Cecilia shaking in ecstacy in his arms, Amalicath's cock continued to fire jet after jet of his demonic seed deep inside her, coating her insides and leaving a trail of white semen trickling down his shaft where it had overflowed. Finally feeling his orgasm coming to an end, the demon lent forward, letting the girl in his arms fall back onto the floor, panting hard into the floorboards as he pulled his softening cock from her pussy.

Standing over her, he admired his work. "That was exquisite. I'll be sure to visit you again soon".

From the floor, Cecilia looked up lazily, and murmured "Please do... master..."

The demon chuckled, before turning away. "Until next time, my little whore." With a flash of black smoke, Amalicath disappeared.

Still on the ground, Cecilia sighed a long, content sigh. Never in her life had she felt something so amazing as the sex she'd just had. Slowly pulling herself up onto her hands and knees, she crawled into a sitting position, leaning against a bookcase for support while her pussy leaked out a small puddle of thick white semen.

Scooping two of her fingers through it, Cecilia brought them to her mouth, savouring the depraved flavour of her patron's seed. As she withdrew her fingers from her mouth, she took a moment to look at them. She clicked them.

From the tip of her index finger, a small flame appeared, hovering in the air with no apparent source of fuel. She looked at it, moving her finger around her face, watching the flame shimmer and dance in the cool air. She smiled. Soon, it would be time for the whole world to learn the name Cecilia Gildamere. She was going to be legendary.
