"Your turn," Nathaniel declared, raising the handcuffs above his head, taunting her.

"Oh, I see." One of her eyebrows quirked up, intrigued.

After tucking the handcuffs back into his pocket, he pushed past her into the apartment, his eyes darting around, searching.

"Heather's gone," she confirmed.

"Good, because tonight I'm in charge." He pointed his thumb at his chest.

"Oh? You're the big boss again?"

"That's right. And I've got a good safe word. Alohomora."

She giggled, delighted. "The spell for opening locks. Very creative. I'm impressed. I see you've come around on the safe word."

Nathaniel stalked toward her with a smug grin. "Because tonight you are gonna need it."

Rebecca regarded him skeptically. She raised her pointer finger and shoved it in front of his face, making a swirling motion. "Ok, who is this? What is all this? Where is this sudden bravado coming from?"

He caught her hand with his and pulled it away from his face. "What, are you worried?"

"About what?"

"That you won't be able to give up control to me."

She scoffed. "Please. You think I'm going to have a problem with lying back and letting you do all the work? Bring it on, Plimpton."

He smirked. "Ok, then this will be easy for you."

She shrugged nonchalantly and started to unbutton the top of her pajamas.

"Wait," he interrupted and put up his hand. Her fingers stopped moving. His tone changed abruptly, dropping the bravado and speaking in a softer voice. "What's ok or... not ok? I mean, I know there's the whole safe word thing, but, honestly, I don't want you to have to use it."

"Oh, um," she thought for a moment. "I guess don't stick anything anywhere we haven't before."

He huffed a laugh at that.

"I think that's it? I mean, I trust you."

"You do?"

"Of course. Also, you can say anything you want, you know."

"Really?" He stepped into her space and cupped her cheek with his hand. "You want me to talk dirty to you?"

"I don't know, Nathaniel. Can you get dirty?" She asked, her eyebrows raising, issuing a silent challenge.

"Oh, yea. I can get dirty. I can get so dirty. I will...take you out to a fancy dinner and be a real gentleman about it."

"So sexy. Go on." She rubbed her hands up and down his chest.

"Then, I'm going to bring you home to meet my mother," he purred and bent his head to plant a light kiss on her neck, "and she'll invite you to the annual Plimpton Christmas party."

A laugh escaped from her throat, "God, I am so wet right now."

Still nuzzling her throat, he continued, "Then, I'll take you to Crate & Barrel and we'll pick out a tasteful ottoman."

She shivered at the sensation of his hot breath on her neck. "Sounds like a busy day," she breathed, her voice husky and thick. She slid her leg up his and he grabbed under both her thighs to lift her into his arms. As he firmed up his grip on her, she wrapped her arms around his shoulders and started kissing him with urgency. He staggered to the bedroom, struggling to divide his attention between walking and kissing her.

They crashed onto the bed in a heap and Nathaniel fervently kissed her, pressing her insistently into the mattress. As they kissed, his deft fingers made quick work of the buttons on her pajama top. When he finished, he parted the fabric and stuck his face between her breasts, kissing and licking a trail from her chest up to her collarbone. She threaded her fingers through the short hairs on the back of his head, applying light pressure, encouraging him. He paused at the base of her neck and bit down on a patch of skin, sucking hard, making her wince. Revenge.

After he was confident he left a mark, he pulled away to unbutton his own shirt, and she helped push the offending garment over his shoulders, eager to feel his skin against hers. When he resumed kissing her, pressing his bare chest to hers, she moaned at the contact.

One of his arms disappeared behind him as he reached for the handcuffs in his back pocket. She propped herself up into a sitting position and pulled her top off the rest of the way, her eyes filling with desire and anticipation for what was to come.

"You're sure this is ok?"

She nodded and put her hands out in front of her. "No, behind your back," he corrected. She bit her lip and obeyed him, moving her hands behind her. He reached around and cuffed her hands together, placing the key on her night table.

"Scoot back." He nodded toward the head of the bed. She awkwardly shimmied up the bed, resting her head on a pillow and shifting to and fro to find a comfortable position on her back. Crawling up her body, he hooked his fingers in the waistband of her pants, catching her panties along with them, and pulled them off, all while keeping his eyes locked with hers.

He kneeled between her legs and pushed them apart, spreading them wider. As he settled down between them, his eyes turned dark, predatory. When she felt his breath lightly tickling her inner thigh, her mouth went slack and she shuddered in anticipation. He paused for a moment to savor the sight of her, splayed before him, just waiting for him to take her. Dropping his head, he planted open-mouth kisses on the inside of her thighs while she squirmed, subtly pushing her hips toward his mouth.

"You're so fucking hot," he gasped against her thigh and he could already smell the heady scent of her arousal. It made him feel primal, powerful, masculine. Not wanting to wait any longer, he stuck his nose between her folds and nudged at her clit. Her hips jerked off the bed and she sharply inhaled at the sensation. He draped a heavy arm across her hips, holding her in place, and used the flat of his tongue to lick her slowly from her entrance to her clit.

"Shit," she muttered and her eyes slammed shut. When he made no move for a few seconds, she whimpered and tried to move her hips, searching desperately for more contact. She finally reopened her eyes and whined, "Please."

He unleashed on her, licking her vigorously, alternating between quick strokes and long, deep ones. When he glanced up at her, her head was thrown back, her mouth agape, and her arms struggled with futility against the handcuffs. For a moment he stopped licking to drag the scruff of his chin against her and she gasped, the sensation sending an electric jolt through her. He then shifted his attention solely on her clit and pushed his finger inside her. The satisfying sound that escaped from her lips was confirmation he was heading in the right direction.

He worked her skillfully, as if they had been lovers for years instead of a mere two months. With previous boyfriends, she sometimes got caught up in her own head when it came to oral sex. She worried about whether her partner was doing it out of obligation, just going through the motions. The anxious thoughts made her uncharacteristically self-conscious and prevented her from truly enjoying the experience. But with Nathaniel, he never hesitated, never gave her an inkling of doubt. He was just as passionate, enthusiastic, and intensely focused on the act of pleasuring her as any other aspect of sex.

He slowly slid his finger in and out, while still sucking hard on her clit. The feeling of her walls pulsing around his finger as he fucked her was almost as satisfying as the sound of his name falling from her lips amidst other words of passion.

As she climbed closer and closer to climax, Rebecca's arms began to ache from keeping her full weight on top of them. "Faster," she panted and he quickened his pace and stroked her slightly harder. "Oh my...fuck…yes…" she said in bursts and he knew she was close.

Seeing her this uncontrolled, at his mercy, in the throes of pleasure, was intensely gratifying. He moaned loudly against her, the vibration from his lips sending a shockwave through her. She gasped a breath, holding it for a moment, and then exploded, crying out as she orgasmed. He released her hips and slowed the rhythm of his finger, staying with her as she rode out her climax.

"Oh my god," she murmured, breathless. Her chest was completely flush, as red as her lips, and her gaze unfocused.

As she came down, he rose from bed and removed his pants and boxers, his erection bobbing at attention, already full and wanting. A hint of a smile graced her lips to see him so ready for her.

"You ok?"

She licked her lips and she could swear she saw his dick twitch in response. "Uh huh," she exhaled.

"Come here," he beckoned. On shaky legs, she rolled off the bed and stood in front of him. Surprising her, he cupped her face and kissed her deeply, lovingly. She was so used to being the aggressor, always pulling at his neck, guiding his lips, that letting herself surrender to his kiss was an unfamiliar, yet welcome change. She followed his lead, melted into him, and the taste of herself on his lips made the kiss feel even more intimate.

When he broke away, it was back to business. "Down on your knees," he commanded. His gruff voice sent a jolt through her and she decided that she needed to let him dominate their sexual encounters more often.

She sank to her down to her knees in front of him. Her clear, blue eyes looked up at his expectantly, dreamily, still coming down from the high of her climax.

He reached down and lightly cradled her chin in his hand. "This ok?"

"Oh yea," she slurred.

"Open," he said, running his fingers over her lips, and it may have been the most erotic word she ever heard someone speak.

She opened her mouth and took him in as far as she could. Nathaniel's eyes rolled back at the feeling of her soft, wet mouth surrounding him. He brought his free hand to join the other, cupping her face gently under her jaw. Guiding her gently with his hands, he thrust slowly into her mouth. She relaxed and leaned into him, completely relinquishing control.

The words spilled out of him, "You're incredible...Rebec...feels so good…" His words washed over her, making her chest tighten and reigniting her arousal. One of his hands moved from her chin to thread in her hair, and he pushed a little deeper into her mouth. A strangled sigh escaped from his lips and his whole body shivered.

His entire world condensed down to the woman kneeling in front of him. For all he cared, a bomb could go off in the next room. There was only her, soft, pliable, and unbelievably, stunningly beautiful before him. He held her chin delicately, tenderly, and, looking down at her, he wished he had the cognitive ability to express how amazing she felt, how she was affecting him. Not just in this moment but always. She had crept into his neatly organized, perfectly arranged heart and blew it wide open. All of these emotions reduced down, compressed into a tiny ball, and released itself as a raw, stifled sound in his throat.

When she raised her eyes to meet his, he was watching her in absolute, unwavering reverence. In her eyes, he saw a vulnerability, but also complete trust in him. "God, you're gorgeous," he whispered. A few more thrusts and he realized he was starting to lose his self-control.

He withdrew from her mouth and struggled to catch his breath. She sat back on her heels and smiled mischievously at his state of complete undoing. He helped her to her feet and then gently turned her around back toward the bed. She crawled up on her knees, and lowered her head to the mattress.

Nathaniel retrieved a condom from the pocket of his pants and she waited impatiently for him as he rolled it on. As he approached the bed, she arched her back, sticking her ass out toward him. He pressed his cock at her opening, teasing her.

"You've been so good, Rebecca." He ran his hands over the small of her back. "Do you want to come again?" She nodded and tried to create more friction by pushing her hips back. He retreated and ordered, "No, say what you want."

A whimpering sound emitted from her throat. She ached for him in a way that made her feel needy, desperate.

"Come on. Tell me," he insisted and then slapped her ass, hard, making a loud clapping noise.

"Ah," she gasped and once again arched her back, begging for it.

"Say it," he growled. He leaned over and grabbed the chain of the handcuffs with one hand and a fistful of her hair with the other.

"I want you to fuck me. Please," she finally pleaded. He immediately slammed into her, releasing his hold on her hair. He roughly gripped her hips, setting a hard, fast pace. Rebecca's mouth fell open as she let out a guttural, animalistic sound, and she fought to meet each of his thrusts.

It occurred to him how much trust a woman must have to engage in this kind of sexual play with a man. Sure, they weren't doing anything too wild, but he also knew he could easily overpower her. (He had indulged her stunt with the pen because her straddling him with unbridled rage in her eyes was the most arousing thing that had happened to him in a long time.) So despite the fact her face was smashed into the mattress and he was pumping into her without mercy, he somehow also felt emotionally closer to her in the moment.

While she was clearly turned on and enjoying this, he realized that he would need further intervention if he wanted her to come again. And he was decidedly not going to be satisfied until she did. He slowed his pace and then stopped altogether. He took a step away from her and opened the top drawer of her night table, retrieving her small, purple, bullet vibrator. Pressing the only button on it, it sprang to life, buzzing noisily. Rebecca, recognizing the sound, turned her head, trying to see over her shoulder.

He returned to his position behind her and wrapped his arm around to press the vibrator to her clit. "Oh fuck," she cursed and he pushed back inside her. He resumed his pace, roughly thrusting into her while she continued to mutter expletives into the comforter.

He pressed the vibrator harder against her clit and groaned, "I want you to come." She screwed her eyes shut, and he watched as her fingers flexed against her lower back and her wrists pulled the handcuffs taut. What would push her over the edge?

You can say anything you want, you know.

"You want me to fuck you like this over my desk?" he rasped.

"Oh god, yes."

He leaned forward ran his free hand around her neck and then through her hair. "I'm going to bend you over and then make you take my..." he started, but he didn't need to even finish the sentence because she shoved her forehead deeper into the bed and cried out in pleasure, her orgasm overtaking her. Watching her fall apart, there was no hope of prolonging the act, and he was coming right along with her. He let go, dropping the vibrator and tightly clutching her hips as he spilled inside her. He jerked erratically a few times, barely able to keep himself upright.

When he finally stilled, he collapsed onto the bed next to her. He used the last of his strength to press the button on the vibrator, switching it off. She rolled over and rested on her side, watching him through half-closed eyes. Her limbs felt liquid, mushy, and heavy as hell. But her wrist ached and she could feel them bruising.

"Hey," she panted and he reluctantly turned his head to look at her. "Can you get me out of these?"

"Oh yea, sorry." He dragged himself out of bed, grabbing the key, and then unlocked the handcuffs.

She sighed in relief and sat up, smoothing the reddened skin of her wrists.

"Are you ok?"

"Worth it," she huffed. He smiled at that and disappeared into the bathroom to dispose of the condom.

When he returned, she was holding the vibrator, a thoughtful expression on her face. "I thought you didn't like Buzz Aldrin," she quipped. She leaned over and returned it to the drawer.

"I can make exceptions, I guess. Especially if it means I can make you come twice."

"Let's not set a precedent, ok? That's a lot of pressure."

He chuckled and leaned down to kiss her. "So that was fun...right?" he asked tentatively, searching her eyes.

"Stop worrying, it was...it was amazing."

"You're amazing."

"Aw, post-coital Nathaniel is so gooey and sweet. Come on." She pulled on his hand, urging him to lie down next to her. He followed and spooned her. Their bodies, damp with sweat, stuck together.

"Now I remember why we always stay at my place," he mumbled into her hair. "This bed is awful."

She giggled and lightly slapped the arm that was draped around her middle.

"Do you really want to have sex on my desk?"

"You're already thinking about sex again? And I thought you didn't want to have sex at work."

"I'll consider it. I'm making all kinds of exceptions for you," he mused softly. She threaded her fingers with his and brought his hand up under her chin, nuzzling against it.

"Could you make one more?"

"Hmm?"

"Would you skip work for a day and take me to the doctor for the egg retrieval on Thursday? I have to have someone drive me home."

He hesitated, but then squeezed her hand. "Of course I will. I'm your boyfriend. That's what boyfriends do. They take their girlfriends to donate their eggs to another man with whom he shares an ownership stake of a law firm."

She giggled and kissed his palm. "Thank you. I'm glad you're making an exception."
