Nex secured Kat's delicate wrists to the bars of the metal headboard with her robe strap, being sure to slip a couple fingers between so it wasn't too tight. He moved down, hovering over her, staring down at her with hungry eyes.

"What's your safe-word?" He asked, bringing his hand up and running it down her cheek gently.

It took everything in him to not pounce on her the moment she told him to tie her up. Normally that would be enough to get him going but she meant too much to him. He told her to choose a word, a word she could say that would tell him to stop if she didn't like something.

"Villanelle," she answered, staring up at him, her eyes drifting down his hard chest, his abs...

"A strange choice, kitten," Nex said, raising an eyebrow.

"You said anything," Kat said, biting her lip.

"I did," he said, running his fingers over her lips. "Fuck, I've been wanting this for so long," he said, bending down and kissing her. Kat's instincts were to wrap her arms around his neck but the ties held her back and a jolt of excitement ran through her, to be at his mercy like this. "Before I do anything I want you to know something," he said, caressing her cheek.

"What?" Kat asked, her heart racing as her fingers curled around the robe strap holding her wrists down.

"I'm yours," he said, pressing his forehead against hers. "I belong to you and that means I only want what you want, Katherine," he said, pressing a kiss against her lips. "So if you don't want something I'm doing, you tell me and I'll stop, all right? Promise me you'll use your safe-word it it's too much."

"Okay," Kat nodded, her heart warming at his tenderness. "I promise."

"This means right now you're submitting to me," he said, dragging a finger up and down her side, making her breathing quicken. "That means for right now I get to fuck you and touch you how I want," he whispered, nipping her ear. "Means I can slide my fingers in you when I want, how roughly I want. Are you sure you want that?"

Kat blushed and nodded. "I'm sure," she said. "I trust you."

"What do you think of the blindfold?" Nex asked, peppering kisses down her jaw and to her neck.

Kat panted softly as he sucked on the skin, trying to focus on his question. "I'll try it."

Nex hummed in approval and ran his hand down her body gently until he reached between her legs. "You sure, Katherine?" He checked again, his finger moving down across her wetness.

"Yes, I'm sure," Kat breathed.

He thrust a finger into her roughly, making Kat cry out in pleasure. "Who do you belong to?" He asked, curling his finger and hitting her sensitive spot.

"You," Kat whimpered, raising her hips to his hand.

"Are you mine, Katherine?" He asked, sliding his finger out and thrusting two back in even harder.

"Yes," Kat clenched, squeezing her eyes shut. "I'm yours, Nex," she said, looking up at him, her lips parted as she panted while he repeated curled his fingers in her, making her gasp.

"Good girl," he murmured, placing a long kiss on her lips before getting off her.

He returned with her red scarf, folding it over before placing it over her eyes, kissing her as he secured it around her. Kat felt even more breathless when Nex pulled away. There was something very thrilling about not being able to see him and not know what he was going to do next.

She was so full of anticipation she jumped when she felt his finger land on her neck and drag down, over the curve of her breast, over her stomach to her hip then down to her inner thigh where it then suddenly disappeared. It was strange, the way a touch like that had her feeling needy for him. He did it again, this time on her other side, this time running over the hardened peak of her breast, making Kat bite her lip as he descended down, almost as if he would touch her but before he did, lifted his finger off her again, making her hips raise towards him.

It was quiet and for what felt like a long time, she didn't feel any contact until she suddenly did. His breath fan out over one side of her neck, his hand on the other, descending down, circling around and over her breast but not where she ached for his touch. She whimpered when his hand moved off her, his lips grazing down her neck, over her collarbone to her breast. His tongue darted out, circling around teasingly just as his finger had done until the contact was suddenly gone. The next sensation came on her thigh, where he dragged a finger up, almost touching her but not quite. Kat whimpered as he inched closer to where she ached when suddenly his addictive touch was gone again.

"Nex," Kat panted.

"Who do you belong to?" Nex asked, wrapping his hand around her throat, his lips brushing against her ear.

"You," she swallowed, licking her lips.

"That's right, kitten," Nex growled, nipping at her hear. "I'll touch you how I want to. You'll cum when I let you. You're mine," he said biting down on her neck and sucking the skin roughly enough it made her whimper and left a mark on her skin. "Mine," he repeated, pressing a kiss to that mark. "Understood?" Kat nodded and Nex growled lowly, biting down on her neck and cupping her breast, pinching her hardened peak hard enough she whimpered and moaned all at once. "Words," he said, pinching her again.

The pleasure mixed with the small amount of pain had heat pooling between her legs more than it ever had before. "Yes, Nex," she panted.

"What's your safe-word?" He asked, his tone softer as he kissed the nipple he pinched, sucking into his mouth gently, erasing the sting of the pinch.

"Villanelle," Kat breathed.

"Do you need to use it?" He asked, caressing her breast softly.

"No," she said, shaking her head. "No. I don't want you to stop."

"So fucking perfect, my Katherine," Nex said, placing a long kiss on her lips that had her chasing after it when he pulled away.

Again, it was quiet and he wasn't touching her. She couldn't stop her heart from racing, her breath from accelerating. Not knowing what he was going to just made her feel more excitable. It felt like forever when she suddenly felt her legs get jerked open. She gasped and held her breath as his hands moved from her ankles, up her legs to her thighs. She whimpered when she felt his hot breath against where she was aching for him to give her attention.

He placed kisses high on her thigh, right above where she wanted him to. She whimpered and raised her hips towards him but he held her down, teasing her, dragging his tongue along her skin but not where she needed it the most.

"Nex," Kat whimpered, her toes curling. "Please."

"What's that, kitten?" Nex teased, running a single finger up her moistened slit, making her hiss and clench.

"Please," she repeated.

"Please what?" he said, kissing her inner thigh. "Lick you, touch you, fuck you?"

Kat nodded fervently. "Yes," she said quickly. "All of that."

Nex chuckled and placed a kiss directly over her clit, making her moan. "You're on my time now, kitten. I'll do those things whenever I damn well please," he said, thrusting a finger into her and making her whimper. "I like making you ache for me," he murmured, sliding his fingers in and out, enjoying the way she whimpered and raised her hips to meet his fingers. "I'm going to make you cum so hard, kitten. I'm going to make you need me," he said, pressing another kiss to her clit before moving away from her, leaving her whimpering and pressing her thighs together. "Don't do that," Nex growled, pulling her legs apart. "Unless you want me to tie your legs down too."

Kat bit her lip, panting. She didn't hate the sound of that. She felt him move away from her and bit back the whimper. She thought she wanted him before but this was different, so much more intense. Even more so when she felt his tongue dart out over her clit, making her gasp.

She raised her hips to meet him but he set his hands on her hipbones, holding her down as he teasingly flicked his tongue over her, enough to make her ache but not enough to send her over the edge. Kat whimpered, throwing her head back as he sucked on her clit, swirling his tongue around her most sensitive spots and stopping just when she felt herself building.

She felt him at her wrists, and frowned in confusion as they stayed bound around her but were released from the headboard. "What are you doing?" She asked.

He wrapped his hand around her throat, making her gasp. "Whatever I want, kitten. Who do you belong to?"

"You," Kat panted.

"Good girl," he murmured, placing a kiss on her lips and guiding her until she was sitting up on the edge of the bed.

"Come here," he said, pulling her until she was standing, making her heart race because she couldn't see what he was doing. She felt him push on her shoulders until she was on her knees while he held her bound hands above her head. Then she felt his hardness against her lips. "Open," he ordered.

Kat opened her mouth and he slid inside of it quickly, making her squeak in surprise. Her eyes slid shut as he reached the back of her throat, making her gag slightly. Before, they took it slow enough she was able to adjust herself and take him in, but this time he came in so fast and hard she wasn't ready. Another jolt of excitement ran through her when he pushed in deeper. Her eyes watered and she felt the blindfold come off her eyes as he pulled out of her mouth, letting it fall down around her neck.

"I'm going to fuck your mouth, kitten," he said, caressing her cheek. "And I'm not planning to be gentle. You can't use a safe word if your mouth is stuffed with my cock, so if something isn't working for you," he said, tightening his hold on her wrist, holding them in such a way her fingers could reach his hand. "Tap me three times and I'll stop. All right?"

Kat nodded and Nex growled, grabbing her throat and squeezing until she gasped. She didn't need to be reminded this time, his actions and eyes said enough.

"Yes, Nex," she gasped.

"Good girl," he said, a smile tugging on his lips. "Keep your eyes on me, kitten. It's so fucking sexy when you look up at me with my cock in your mouth. Open."

Kat opened her mouth and let him slide in, doing her best to keep her eyes open and up at him. He threaded his fingers in her hair and held her in place as he started thrusting in and out of her mouth. Kat moaned softly, the sensation creating a vibration in her mouth that had Nex cursing and groaning from how good it felt.

He continued thrusting in and out of her mouth until he couldn't take it, until Kat's sounds became too much for him to handle on top of the way it felt to be in her warm mouth. He sunk himself deep inside her, going down her throat and making her eyes widen. Kat's eyes watered even more and he stayed there, pulsating in her until he was finished. He slid out and stared down at her, releasing her still bound wrists. She wiped her mouth and looked at him. Those green eyes could suck him in and make him forget anything.

"Up," He ordered, grabbing her wrists and pulling her up and into a kiss. "Good girl," he growled, kissing her roughly.

She moaned and dropped her arms over his shoulders. He lifted her and placed her on the bed, ducking out of her embrace and replacing the blindfold over her eyes, retying her hands to the headboard above her.

"Are you going to touch me?" Kat breathed, lifting her head as if she could see what he was doing.

"You were a good girl, kitten," Nex murmured, dragging his finger down her body. "Good girls get rewarded."

His hand moved away from her and she held her breath, wondering what he would do next. Then she felt his mouth on her and moaned, tugging on her restraints and writhing under him. Everything up until now made her so sensitive she felt like she would explode and she did, cumming faster than she ever had before, the orgasm hitting her in intense, repeated rushes of pleasure like she never experienced.

Kat's body relaxed and she sunk back into the bed, panting. Nothing had ever felt so good and also left her so exhausted. She thought maybe that was it but then she yelped as he flipped her over onto her stomach and lifted her hips so her ass was in the air.

"I'm not done," Nex said, caressing her ass. "I'm not even close to being done, kitten. I'm going to claim every inch of you."

"What are you going to do?" Kat breathed, licking her lips.

Her response came with a smack to her bottom that had her yelping. A stinging sensation spread over her at the same time her core clenched, a moan escaping her lips from the sensation.

"You don't get to ask questions when you're submitting to me, kitten," Nex said, caressing over her ass until the stinging faded. "Do you need to use your safe-word?" He asked, pressing a kiss against where he smacked her.

"No," Kat panted, swallowing hard. "I... I liked it."

"You liked it?" Nex repeated, straightening out and smacking her bottom again, earning another yelp followed up by a moan.

"Yes, Nex," she breathed, biting down on her lip.

"Fuck, you're going to be the death of me," he groaned, spreading her legs a little before dipping his head between her legs.

Kat moaned at the angle change and just when she was getting close, he stopped. She whimpered in protest and he smacked her ass, silencing her. He pushed his fingers into her and did the same thing, pumping them in and out over and over then stopping when she got close. She knew whimpering would earn another spank but part of her craved to feel that again so she whimpered, moaning when his hand came down hard against her ass.

"Nex," Kat whimpered when his fingers slid out of her again. She'd lost count of how many times he'd done it. "Please," she panted, unable to hold her body still, squirming on the bed.

Her response came with his hand around her throat, his hardness pressed against her backside. "What did I say?" He asked, his hand tightening around her throat, making her gasp. "I said you're on my time," he growled, smacking her ass. "I'll let you cum when I want you to. Do you need to use your safe-word?"

"No," Kat panted, shaking her head. Despite the fact she was aching for him something horrible, she wanted to keep going, craved to be with him in this unfamiliar but intimate way.

"Good girl," he murmured, kissing down her back, smacking her ass again as he sat back, setting his hands on her hips and staring down at where she was dripping for him. He brought his finger up, teasing the outside of her, enjoying the way she whimpered and dropped her head on the bed. "What's wrong, kitten?" he asked, sliding a finger into her, making her whole body tremble. "Feeling like you need me inside you?"

"Yes, Nex," Kat breathed.

"Do you want me or do you need me?" He asked, sliding the finger out, taking his hands off her.

"I need you," Kat whimpered.

"You need me to fuck you, kitten?" He asked, grabbing hold of himself and pressing his tip against her, making her tense in anticipation.

"Yes," Kat said quickly. "I need you."

"Say it again," he ordered, smacking her ass.

"I need you," Kat panted.

"Again," he repeated, smacking her ass again.

"I need you, Nex," Kat whimpered.

Nex groaned and grabbed her hips, holding her in place as he thrusted into her hard.

"Nex," Kat cried out.

"Who do you belong to?" Nex growled, smacking her ass before caressing it, erasing the sting, enjoying the way her skin turned red.

"You," Kat breathed.

"Good girl," Nex murmured before he started sliding in and out of her roughly, his hand sliding down her spine until he reached her neck which he grabbed the back of, holding her down against the bed while raising her hips with his other hand and sinking into her harder.

Kat moaned and cried out at the new sensations, clenching around Nex and making him groan. It wasn't just the intensity of the action, it was the trust she had with him and only him, the way he made her feel cared for even now, the way she felt like she was seeing another side of him, a side she very much liked. She wanted to see all the sides just as he wanted to see hers. Every motion felt much more than physical, it was as if each action brought them closer together, as if they were one. Nex moved in out of her wildly, holding her in place and sinking in deep and hard when he came, moaning as she clenched around him, finding her own release as well, trembling as she cried out, her whole body tensing and relaxing over and over until she finished.

Nex panted and bent down, kissing her back and gently caressing her ass as he slid out before quickly turning her over and untying her wrists, removing the blindfold and catching her in a soft kiss. Kat moaned and wrapped her arms around him, enjoying the way it felt to have him wrap his arms around her and hold her close after that intensity.

"You didn't use a safe-word at all," he said, kissing her forehead. "You promised me you would if it was too much."

"I didn't need to use it," Kat panted, still trying to catch her breath. "It wasn't too much."

"Fuck, Katherine, you're so perfect," Nex murmured against her lips. "So fucking perfect, my kitten. My angel," he said, pressing his forehead against hers. "I..." He stopped at the words he almost said. Words he'd never said to anyone before and words he didn't think he was capable of saying. There was no denying what she meant to him but he couldn't say it so he opted for something less terrifying.

"I'm glad you summoned me, too," he said, rolling over and pulling her into his chest, holding her close and thinking the words he couldn't bring himself to say, keeping them locked in his own mind as the realization of what he felt for her really sank in.

It wasn't supposed to be this way. He wasn't supposed to be able to feel anything like this but he couldn't deny it. She was everything to him. He'd never been more himself than when he was with her, he'd never felt more at peace than he did when he was with her, he never craved something as simple as a hug with anyone but her.

He'd never been able to stop the self-loathing he felt as a demon until she came in and made him think he could be something better.

He ran his finger down her cheek, staring down at her flushed face. She meant too much to him for it to not be true. There was no denying it but because he couldn't bring himself to say it, he kept it in, only allowing himself to admit the feelings within his own mind.

I love you.
