Notes

Steve stared her down with a playful look. He had intentions, though she didn't know all of them yet.
Nikki shivered at his gaze upon her, covering her chest with her arms and avoiding eye contact. He lifted her chin up, speaking softly.
"Follow me".
Before she could open her mouth to respond, a sharp pain tugged at her soul. He gripped it rather harshly, forcing her to stay by his side as he walked. She whimpered, attempting to break out of his grasp. He pulled her closer by her soul, almost dragging her. Nikki fluttered her wings rapidly, trying to lift herself, but she got pushed right back down. Giving in, she slowly slid her hand onto his, holding onto it like a small child. Their difference in hand size comparison could seem almost to a father and his child.
He let go of her soul, picking her up when they got to his room. She fit perfectly between his arms. He placed her down onto his bed and drew the curtains, as so nobody could watch them do their deeds...
Locking the door and flicking off the small chandelier lights that hung above them, Steve crept slowly onto the foot of the bed, peeking his head up between her knees with a malicious fanged smirk. He growled lowly, signaling he was feeling lusty. She blushed, pulling her knees up to her chest and closing her legs. That didn't stop him, though. He pulled her by her ankle playfully towards him. She shrieked and giggled, falling backward to leave the lower half of her body to the mercy of the tall man who loomed before her. He liked this.
Carefully tracing the shape of her leg, he dragged a finger up her thigh, gently lifting her skirt up. She flustered, her legs tensing together again. He pushed against her knees, forcing her legs wide open. Nikki purred awkwardly, liking the attention but also embarrassed by the position she was caught in. Her tail flicked up, draping over his hand and wrapping around his wrist. She lightly pulled on his hand, guiding it down to between her legs. She let go, as his hand slid her skirt up to expose her black lace panties where her thigh highs were held in place. Oh, how excited this made him. He eagerly pulled off his tie, kicking off his pants and undressing down to his turn-down shirt and boxers. She bit her lip and watched impatiently as he unbuttoned the last article of clothing he had on besides underwear. Her eyes twinkled subtlely, the buttons on his shirt began to glow with blue-green magic. She was unbuttoning the shirt for him.
She was much faster at it, to say the least. It was kinda embarrassing.
In a swift movement, off went her clothes. She tossed them across the room into a pile and grasped onto his shoulders. She pulled him down on top of her and wrapped her legs firmly around his waist. He gripped her thighs and squeezed her butt, earning a yelp from her. He chuckled, leaning down and kissing her cheek. Steve gently left a trail of kisses down her cheek to her neck, whimpers and whines escaped her throat in return. She whined again, lazily running her hand through his soft hair. He lightly pressed his front fangs against her skin, making her flinch, as a rush of excitement burst through her.
"Ghh... Bite me please...~" she hissed, squirming in anticipation. Steve laughed silently against her neck, amused by her neediness. He kissed his way down to her collarbone and, without warning, bit down and punctured her skin with ease. She gasped, a small pathetic moan spilled out from her throat, begging for more.
He sank his fangs down further, feeling a small, trembling hand pull his hips down against hers.
He followed her body language, pushing himself against her aching core. Another breathy moan escaped from her, trying to desperately get some sort of friction to relieve her building tension. Steve pinned her wrists up over her head, his fangs still locked in her skin, slowly feeding off her magic, rather than her blood. He ground his pelvis down, giving her the rough friction she wanted. Nikki lifted her hips up, attempting to aim his grinding against her favorite spot. He lifted his head slowly, a mix of blood and magic dripped from his fangs. He licked them off and looked down at her flustered face. He found her cute like this.
Steve exhaled and slammed his hips forward, making her shriek in pleasure. Nikki wriggled her wrists free. She grabbed and tugged on his wings, making him grunt and shudder. God, if she kept this up he would cream himself before he could even get his boxers off. Steve managed to open his stiff wings, his tail flicking back and forth quickly in excitement. She ran her hand down the length of his wings, rubbing and petting them at the base. She felt the bulge in his pants quiver as he began to pant lightly. "Nikki..." he groaned in ecstasy, "T-too much stimulation...".
She grinned, letting go, as his wings relaxed down and laid against his sides. He tugged her panties down, unclipping her thigh highs with them. Steve scooted down to face her lower regions. He could feel the heat radiating from between her legs, as she wriggled and whined, wanting to feel sensation down there.
He pulled her knees open and slid his hand down. His thumb gently pushed against her sweet spot, while a fingertip ran up and down--what he liked to call--her 'V-nus' (hehe see what i did there-)
Nikki cried out, her wings popping open as a reflex. They quivered, as he used his available hand to pet them. Her tail began to twitch and flick, as she was already getting close. He noticed this and stopped. He smirked and licked his fingers off, leaning down to leave kisses between her legs. Nikki spread her legs further, whimpering.
Steve slowly kissed down her labia, she quivered and cried out again, not able to find the words to beg to be touched. He chuckled and hummed lowly, sending little vibrations through her. Nikki squeaked, pushing her hips forward towards him. He licked at her gently, dragging his tongue up and down frustratingly slowly.
Somehow finding her words, Nikki choked out between her whimpers, "M-more... I want more, master!".
"What do you say?" he hummed into her again, making her tremor. She was so close.
"P...Please...".
"Good, dollface.".
He licked at her roughly, using his hand to stroke her sweet spots. Nikki's wings flapped and her hips bucked, screaming out his name. The orgasm slammed over her, making her see stars and bright colors.
"GHhaAHAaa!!~~" she cried out loudly enough for half the castle to hear. Thankfully the door was closed.
Her fluids spilled out of her, as he tried to lap all of it up.
She ground her hips against his tongue, riding out her orgasm. After a long, messy climax, he lifted his head to let her catch her breath.
He chuckled, "That quickly, huh?".
"I... needed that... C-can we keep going?" she squirmed, still having some energy left in her... somehow.
Steve grinned, pulling off his boxers and climbing on top of her.
"We'll keep going until all that pent-up stress of yours is gone. How's that sound?".
Nikki nodded and giggled, running her hands through his messy hair as he aligned himself at her entrance.

And on they continued, for hours and hours.
