Twenty minutes later, he was in his bedroom. Of course, he was. He had to know just how Casey planned on taking care of him. He still felt guilty about it. About her taking care of him when it should have been the other way around. He owed her everything. And yet that small vulnerable part of him ached for the attention. For her. And so he gave in.

The overhead lights of his bedroom were turned off when he stepped inside. The reading light above her favorite armchair illuminated his seat like a beacon. Accepting his fate, he slipped out of his dress shoes and pulled off his suit jacket, throwing it on the foot of the bed before slumping into his seat.

Taking a deep breath, he looked around the room for another trace of her. The only thing he noticed was the strip of light spilling out from underneath his closet door. Was she in there?

She didn't let him wonder for long. She must have heard him come in because the closet door opened and she slipped into view. The first thing he noticed was that she wore one of his crisp white dress shirts. The hem skimmed her mid-thigh. But unlike him, she wore it open; like a cover-up. Half of the shirt had slipped down past one of her shoulders, exposing all her soft skin, and peek of a bra strap. Beneath the shirt, she wore a black bra and underwear set. It was simple from as far as he could tell. But it didn't even matter. She was the only thing that mattered.

She made her way over to him, her bottom lip caught between her teeth. He felt his heart rate climb with every step towards him with her bare feet and painted toes. Sure she had worn cute little sleep sets or satin slips to bed with him, but never was she so bold to wear anything resembling lingerie. Whatever was happening between them was new and they were crossing some sort of invisible line.

His eyes trailed up towards her face again. Her hair was down, cascading over one shoulder and her face was bare of makeup. He wouldn't have it any other way.

"What's your safe word?" she asked when she finally stood in front of him.

Derek took a second to gather his thoughts, his eyes greedily drinking her in for every single detail of her. She was breathtaking and he was just a man.

"Casey," he hissed her name, finding a little bit of restraint. No. He did not deserve this, her, and whatever she had planned. But fuck if he wasn't selfish enough to still wanted it.

Casey shook her head playfully in response. "No, that won't work. Try again," she prompted him softly, still not making a move to touch him.

Derek sighed, he was strong enough to push back again. She had her out, and she didn't take it. "Red," he finally breathed out.

Casey beamed down at him like he had done something worth praising. "Good," she purred. "Tie please," she instructed him, holding her palm up face up, showing him exactly where she wanted it.

He eyed her hand for a second, letting her demand to sit between them for a beat. Casey eyed him carefully, not moving an inch, expecting to be heard. And so he did, slowly undoing the knot at the base of his throat, slipping the smooth fabric across the inside of his collar, and handing her the tie in question.

Casey looked down at her hand and smirked. "Hands behind your back."

Derek arched an eyebrow in her direction. He was genuinely surprised to hear her request. But being on the receiving end of her heated glare, he decided to do as he was told. Slowly he moved both arms around the back of the armchair. The chair was a little wide, so his hands didn't meet, but Casey was resourceful and still made it work. All he could feel was the soft material loop around his wrists gently. It was hypnotic almost, the way he let his control slip from his hands and straight into hers.

He trusted her.

"That ok?" Casey asked coming around to him again.

He gently pulled at the knot, making sure it held. He knew he could break out of it easily if he tried, but that wasn't the point. So he simply nodded, letting her know she was good to go.

"Good," she smiled.

And then she climbed into his lap. Her knees pressed into his hips. Her calves were parallel to his thighs. Her chest was wrapped up in that soft black material only inches from his face. Fucking perfection.

Her smell covered him like a blanket. His fingers itched to get lost in her hair. He wanted to tuck his nose into the crook of her neck; to inhale. But he couldn't. He was at her mercy. And what a sweet surrender it was.

He didn't know where to look. What to focus on. But then her hands pushed him deeper into the plush chair, forcing him to look up into her eyes where those blue sparkled.

Please with his reaction, her hands dragged down his chest, her fingers making quick work of unbuttoning his white shirt. One by one she popped each one open till she was able to push the fabric apart and reveal his chest. Her fingers danced along his bare skin, paying special attention to his scars and tattoos. She studied him with laser focus and fuck if that didn't make him feel special.

His hips arched up just a bit, but who could blame him? She had fallen into his lap so gracefully and was teasing him in every way imaginable.

Casey giggled like he was cute. "Behave," she reminded him, with no fire behind her words. But then those wandering fingers found his belt and without a second thought, she let her knees slip and hit the plush carpet beneath them.

In what world was Casey ever on her knees for him? In this one, apparently. And he couldn't fucking breathe trying his best to soak in every detail about it.

"Is this ok?" she asked, her fingers toying with his belt buckle, not moving to open it just yet.

Derek groaned, canting his hips up to her hands. Yes. Fuck yes. He nodded furiously, hoping she'd get the memo.

She smiled up at him again this time those fast fingers undid his belt and popped open the pants, sliding the fly down slowly, teasing him in a way he hadn't felt in a very long time. Casey's warm hand palmed him over his black briefs. It hadn't been the first time she touched him, but he was spiraling fast. He wouldn't last, but he really didn't seem to care.

Quickly she grew impatient with her own teasing, pulling on his pants. "Up," she instructed, pulling the dress pants down his hips and legs till the offending garment was completely off of him.

There he sat, in his briefs and an opened dressed shirt, hands tied behind him staring down at her with undoubtedly a flushed face. He didn't dare speak, he didn't want to break whatever spell she had spun around them.

"Der," she called his name softly. Her palms dragged up his toned thighs at a tedious pace. He simply watched her hands, as they made their way to where he wanted them most. And then she bent her head, her lips coming to press wet kisses along his exposed thighs.

The groan that slipped out of his chest was borderline embarrassing. His head was thrown back, his eyes hazy and unfocused.

"Eyes on me," she reminded him gently. It took all the energy he had left to bring his head up and his eyes down to her.

"There he is," she whispered with a pleased smile. "I've got you," she promised, his fingertips slipping under his briefs. "Can I take these off?" she asked, her face nuzzling into his thigh. Her warm breath teased him over the black stretch cotton that covered him.

The man couldn't breathe, or form a cohesive thought.

"Der?" she asked, pulling back to look at him.

Finally remembering there was a question he had missed, he nodded. As far as he was concerned, she could do anything she wanted. Didn't she know that? He had no limits. Not with her. He'd take whatever she gave, freely and willingly, and he'd even thank her for it after.

Her fingers reached for the band of his brief, and this time he lifted his hips before she got a chance to ask. Casey rewards him with a little smile.

And suddenly he was sitting there, oh so very exposed, and Casey was staring at him. He didn't feel an ounce of shame or discomfort. Her fingertip teased him with a barely there touch that had his spine tingling. He would beg if she needed him to, but fuck he just wanted wanted wanted.

"Remember your safe word," she cooed gently. And then her tongue slipped past her lips, and the heat of her breath fanned over his overheated skin. And then her soft tongue was licking the vein that ran underneath him.

"Fuuuuuuuuuck," he cursed. The word ripped out of his chest without his permission.

He hadn't felt Casey's mouth before. But oh that soft wet tongue worked up and down his length with teasing little licks. Her lips pressed kisses along the sides, peppering him with all of her attention. And then she wrapped her lips around him and he was done for. He didn't exist in the world.

It wasn't long before he was close. He tried to warn her. He really did.

"Ca-"

But hearing him, she doubled down her efforts, taking him down deeper, sucking a little harder. And he was gone gone gone. He wasn't sure what kind of noise he made. Or what his body had done. He just knew he was floating gently in the space between reality and a dream; basking in euphoria that he could never provide himself.

Eventually, when he came back to himself, he looked down at her. She was still kneeling between his legs. Her lips were swollen and perfectly pink and wet. Her thumb came to wipe at the corner of her mouth. The shirt she had been wearing was lost at some point, leaving her in her black set. She looked like a goddess in front of him. Kind of like one of those Greek paintings. Maybe he should commission someone to paint her.

Before he could find enough brain cells to speak, she was in his lap again. She reached around him to pull on the makeshift knot she had made, releasing his hands. Steadying herself in his lap, she cupped his face in her hands and looked at him like he was precious or something.

"You alright? she asked softly.

He just nodded. He was more than alright. But his systems weren't up and running just yet. His hands found themselves curled around her hips, sliding down to the globes of her ass, pressing her into him. She was warm, so fucking warm, and right there. It wouldn't be any work to be buried in her and return the favor tenfold. He just needed a minute. But his mouth would do in the meantime.

Casey shook her head, bringing his hands back to the safety of her hips. "None of that," she told him. "I just want to take care of you," she reminded him, pressing soft kisses all over his face, her fingers in her hair, her nails scratching at his scalp. He felt so soft and cared for. A foreign feeling he hadn't been able to wrap his head around yet.

"Think you can make it to the bed?" she asked after a minute or of fussing over him.

Derek didn't respond. He simply tightened his hold on his hips, and stood up, scaring her for a second, before depositing them in his bed.
