Ok, boys and girls, this is it. This is the chapter your mother warned you about. When I began writing this story, I made sure that you could skip the naughty bits if you wanted to. If that's your goal, you'll want to skip this chapter.

If, however, you're here while you're waiting for Pity for the Devil to update, this is the chapter you're looking for. The theme song is "Undisclosed Desires" by Muse.

Chapter 36: Undisclosed Desires

Natasha slammed the door, and stared at her hand, still fisted in his shirt. Slowly, very slowly, she looked up his neck, past his chin, and at his lips. They were parted slightly, and he was breathing quickly. She glanced up at his expression; he looked as if he couldn't quite believe his luck. She pressed him up against the door, sliding her hands up his chest and into his dark hair. His hands found their way to her back, resting feather light, as if he were afraid she would disappear if he held her any tighter.

She swallowed, gathering all her courage, and kissed him. Her lips slid against his slowly, and she sighed at the tingling sensation. She groaned a little against his mouth as his hands lowered to cup her bottom, pressing her against his hips gently. "Oh, my god," she murmured.

"Yes, yes I am," he quipped before capturing her mouth again. The kiss turned frantic, and she released her hold on his hair with one hand, dropping it to begin fumbling with the button on his pants.

"No, slow down Natasha," Loki said breathlessly.

"What?" she stopped, looking up at him, a frown of confusion on her face.

He brushed a few curls behind her ear. "I want to do this right… I want to—"

"No," Natasha interrupted him, almost angry. "I don't want something that you think I'll like. I want you Loki, in all your fucked-up glory."

His breath hitched a little. "Really? You're sure?" he asked with a warning tone.

Natasha ground her hips against his for emphasis. "Yes," she whispered.

Loki let out a long, shuddering breath, and a wicked smirk tugged up the corner of his lips. "As you wish."

Natasha gasped as his hand flew up to her throat, and he turned, slamming her against the wall. He kissed her roughly, all previous tenderness gone, his body pinning her in place a few inches off the ground. She scrabbled for a hold in his hair, but he captured her hand and pressed it against the wall with far more force than necessary. He began to tilt his hips against hers in a sharp, slow rhythm, breaking the kiss and burying his face in her neck.

She found that if she turned her head, her mouth had access to his ear. She drew the lobe into her mouth, biting down and dragging on it slowly. Natasha was rewarded with a low, desperate moan from Loki. He began to pull her captured hand down, sliding it between their bodies until she could feel him, hot and hard through the leather.

"You see what you do to me woman?" he hissed in her ear.

She moaned, she couldn't help it.

"That's right. You like this don't you?" he began moving her hand up and down as he bit her neck, slowly but hard. She whimpered in response.

Suddenly, he pulled away, and she nearly fell over as she slid down the wall, dizzy and out of breath.

He stood a short distance from her, breathing equally hard, and slowly, deliberately raked her with his eyes. He worked his way up from her shapely legs, her full hips and slender waist, her ample breasts, her long, lovely neck, and at last met her eyes, wide and dilated.

"Kneel." His voice was low, soft, dangerous. It promised naughty things.

Her mind was so fogged, for a moment she couldn't think. Then it clicked. Oh Natasha, I don't need my magic to make you kneel. He was right. Slowly, deliberately, she knelt before him, pressing her cheek against his hip, just a few inches away. As her fingers found his fly, he threaded his in her hair, taking a tight grip. She pulled the zipper down slowly, and he sprung free, surprising her. She took a moment to admire—it was impressive, after all—and then looked up at him with a raised eyebrow.

"Does Tony know you're running around commando in his clothes?" She asked teasingly.

He looked down at her, his lips pressed together. "I won't tell if you don't," he lilted.

She took hold of him quickly, hard, and he gasped. "You little minx…" he muttered through clenched teeth.

And then she really went to work on him. She had to admit, he was delightfully responsive.

"Oh, Natasha yes…" he whispered, his voice softening, even as his hand in her hair demanded more. She found a good pace, and was just beginning to believe she had the upper hand, when he suddenly pulled away. "Fuck, Natasha…" He grabbed her wrist and pulled her up to standing, burying his face in her hair and breathing rapidly for a moment. He pulled back a little, just enough to look into her eyes. "Bedroom. Now."

She nodded, breaking away and heading for her bedroom door. She hit the switch to close the curtains as soon as she got in. No one is going to watch this show… she thought with a smirk.

Loki came up behind her, pulling her hips back to his. He had done his pants back up and ditched the jacket, and was doing interesting things to her backside. He sighed heavily as he looked at the room over her shoulder.

"What?" she asked.

He continued moving his hips against her subtly as he spoke. "It's just… this is all much easier with magic…"

She turned against him, looping her arms around his neck. "What is?"

He gestured to the room behind her. "This. There should be lighting, music, mirrors."

"Mirrors?" she asked with a raised eyebrow.

"Yes." He turned her back around, forcefully, and ran a hand up her front, squeezing her breast firmly. "I like to watch you, Natasha," he breathed in her ear. "I want to watch you watching me fuck you." He slowly pulled the zipper down on her jumpsuit.

She moaned, and then he shoved her into the room. She stumbled a little, turning around to see him stalk after her. He stopped just short, and finished pulling the zipper down. He slowly slid the shoulders off onto her arms, a grin coming over his face as her green lacy bra revealed itself. "Oh, so you do hold a candle for me, Miss Romanov?"

She smiled a little. She knew it would give her away, she just didn't expect him to see it so soon.

He continued pushing the top of her jumpsuit off, freeing her arms, but paused when he realized he would need to get her boots off first. "Damn," he cursed softly, and shoved her down onto the bed before grabbing her legs and flipping her over. She clutched the covers as he tugged one boot off and then the other. Then he spread her legs and positioned himself between them. He slid his hands up her bare back slowly, deftly undoing her bra with one hand while the other grasped the back of her neck. He tilted his hips into her, and was rewarded with a soft moan. "Curse this outfit," he said in an incongruously sweet voice. "I want you in a nice, short skirt."

She managed a quick flip onto her back, wrapping her legs around his waist. "Like London?" she smiled, sitting up.

"Yes," he toyed with the loose strap of her bra, "I can't tell you how much I love watching you work."

She tilted her head a little. He had been in his other form at the time, but she supposed he remembered everything, after all. She tugged on his shirt playfully, and he quickly shed it. He hooked the front of her bra with one finger and tugged it off her finally. He devoured her with his gaze as he slowly pushed her back down onto the mattress. He followed soon after, pressing the hard, smooth planes of his chest against her softer curves.

"Oh, Natasha," he groaned. "How I've dreamed of this."

She responded by wriggling provocatively under him, managing to free her legs from the jumpsuit. Loki sat up, kneeling on either side of her hips. He took a moment to admire the way she looked, spread out beneath him with her cheeks flushed and her lips swollen from kissing. Then he grabbed her by the waist and quickly slid her up the bed.

She cried out, surprised, and looked down to see him stroking one of her legs contemplatively. He ran his hands up her legs and up onto her hips, his fingers hooking around her thong and slowly, teasingly pulled it down. He tossed it away, and then slid a hand back up between her legs, spreading them.

"Loki…" she moaned.

"Shh…" He settled himself between her legs, kissing the inside of her knee and working his way up. As he neared his destination, she couldn't help arching up in anticipation. He splayed a hand on her stomach and pressed down, looking up at her with a heated expression. "Don't move," he warned, his breath tickling against her most sensitive spot.

Natasha let her head fall back onto her pillow as he began his slow, deliberate torture. He teased her mercilessly, and then lavished her with attention as soon as she lost hope. He built her up this way, higher and higher, until she thought she might scream of frustration. She tried reaching down to wind her fingers in his hair, but he swatted her hands away, looking up and chuckling.

"Eager, are we?" he teased.

She whimpered in response, bucking her hips a little.

The hand that had kept her hips locked down began to move downwards, his fingers trailing through her short, red curls. He flicked her lightly, and she cried out. He smiled a little and moved lower, finding her center and slipping a finger in, his thumb continuing to press her buttons.

"Oh, Natasha…" he groaned. "You're so wet… you really do want me." He opened his eyes to look at her, and there was a moment of pure vulnerability in his expression.

"Yes," she gasped. "Please."

A grin broke over his face like the sun rising, and he sat back, licking his fingers, making her moan. "Well," he stood, and removed his pants and boots quickly. "You don't have to ask twice." He moved up the bed over her, reminding her very much of a panther stalking his prey with his black hair and green, green eyes.

They both moaned as he pressed his body to hers, every inch of skin touching. He grabbed her wrists quickly and pinned them above her head with one hand. With the other he palmed her breast, rubbing his thumb over her little pink nipple.

She cried out in response, and he chuckled. "Oh, you like that, do you?" He took the raised peak between two fingers and rolled it a bit, before pinching. She arched her back as sparks of pleasure—or pain, at this point she wasn't sure—lanced into her. He continued until she thought she might scream, and then he released her and replaced his fingers with tongue, lips and teeth.

"Loki!" she shouted, shocked at how much more sensitive she was now. He moaned against her and moved to work on the other breast. She tugged at his hold on her wrists, but he wouldn't let go. He began a slow rhythm, rocking his hips against her, and the effect with nothing between them was marvelous. She tried lifting her hips to offer him entry, but he only chuckled and pulled back.

"Loki, if you don't stop teasing me right now, I swear I will kill you," Natasha ground out.

He chuckled at that, too. "On your knees again, then, girl." He flipped her over and she rose on all fours obediently. He took hold of her hips and pulled her against him, grinding in much the same manner.

"Loki, I mean it!" she warned.

No sooner had she spoken than he pulled back and found his way in. He went slowly, torturously, fulfilling the letter but not the spirit of her request. She tried to press back against him, but he held her hips in a vice-like grip.

"Loki, please…" she begged him.

"Yes?" she could hear the smirk in his voice, and realized she would have to be more specific.

She buried her face in the pillow a moment, and then looked at him over her shoulder. "Fuck me, Loki. Please."

His eyes widened—he hadn't expected her to be that provocative. He complied immediately, almost without thinking, slamming into her deep and hard.

She cried out, her toes curling. "Yes," she gasped. "Faster."

Loki was happy to oblige, and quickly lost himself in the rhythm, his hand sliding up her back to press her down into the bed.

Her hands clenched on the bedcovers as she felt the first waves of her climax approaching. "Oh yes, Loki, please, just like that…" she murmured, before stiffening as she was overtaken. She gasped, seeing little flashes of light behind her eyes.

"Natasha," Loki groaned, digging his fingertips into her. "Ah, Natasha, you feel so good when you come for me…" he leaned forward to whisper into her ear, and she could feel his ruby pendant brush against her back. "Do it again."

She screamed as her body complied, shocking her. Loki straightened up, cursing, as his rhythm became more erratic. "N-natasha, yes!" he whispered as he came to his release, pressing into her once, twice, three times, and then collapsing.

Natasha straightened out her legs and let him rest above her, relishing the feel of his weight pressing her into the mattress. He lavished tiny kisses on her shoulder blade where he rested his head while he caught his breath.

"Oh, my sweet, lovely girl," he whispered, brushing her hair out of her face. "You are a thing fit for princes." He drew away from her slowly, and dropped heavily onto the bed next to her.

She turned towards him, catching her breath. "What about gods?" she asked teasingly.

He reached out and pulled her to him, so she could feel his heart pounding in her own chest. "No," he claimed her lips. "Only one god shall ever grace your bed, if I have anything to say about it." He held her to him tightly for a moment longer, and then sat up. He swung his feet onto the floor and stood shakily.

Natasha took a moment to admire his nude figure, and could only be reminded of sculpture. He ducked into the bathroom quickly, and came back with a towel which he tossed to her.

She caught it, laughing, but then frowned when he began reaching for his pants. She jumped up to her knees, catching hold of his wrist.

"Where do you think you're going?" she asked teasingly.

He straightened up, running a hand through his hair. "I…"

Natasha remembered too late that he had little experience with the more emotional aspects of sex. She tugged on his hand, giving him a small smile as she sat back on her heels. "Stay, Loki…"

He stepped towards her, but still looked unsure.

"I have more to show you," she promised.

He smiled at that, and let her pull him back into bed.

A/N: Tada! Sorry you had to wait for it so long, but the primary focus of this story is character development, and a LOT of it had to happen before I could make this work. Stay tuned on Wednesday for more sexiness and then some serious conversation in "Give a Little More."

Reviews, as always, keep my muse appeased and cooperative.
