Ok guys, warning time! This chapter is the one I've been dreading writing... The sex scene! Honestly, I've never written anything like this, so if you have any pointers to help out in the future, please don't be shy. You all know the rest, don't like, don't read, blah blah blah...

Thank you so much for all of the reviews, favourites and follows, it means a lot that you guys give a crap about my story, especially as I never thought I'd get more than three reviews!

Ok, well, on to the story! All my love

It took the pair a good few minutes of kissing and fumbling to get the damn dress off. Kat hadn't thought of that particular detail whilst planning the night, but she had to say, the look on L's face when the blue fabric pooled on the floor around her ankles was worth it.

"You're... Beautiful." L's voice came out in a hushed whisper, his slate eyes wide as he took her in. Sure, over the years he had seen her naked, but never like this. She wore only a pair of lacy white panties, nothing more, nothing less. Her skin was pale, the colour of milk mixed with caramel, and her dark hair fell around her like a frame. Her eyes were hooded, her cheeks flushed, and her naturally pouted lips swollen from his kisses. She had a few scars scattered around her upper body, a result of her abusive upbringing, but it only made her even more beautiful in his opinion. It showed how strong she was, how brave.

"Come here." She pulled him close, releasing a few buttons on his shirt to expose his chest. He helped her, pulling the shirt over his head and throwing it to the floor.

Kat let her arms snake around his shoulders, their naked chests touching. The pair hissed at the connection, their conflicting body temperatures shocking the other. Kat was hot while L's skin was chilled, like he'd been sat by a window for a while. She couldn't bring herself to look away from his face, constantly searching for any sign he was unsure. She trusted him with her life, she knew he would never hurt her, but she knew he wouldn't say anything if he was uncomfortable. He would stay silent and bare it, and Kat in no way wanted that.

L's hands found themselves on her hips as he leant down to kiss her. She was so soft and warm, so alive. She was like the light in his otherwise cold and darkened world, the one reason he could be strong. If it wasn't for her, he wouldn't be the man he was, the brilliant detective and adoptive father. He would have probably let himself waste away, wether intentionally or not, and his perspective would be so different.

"I love you." He whispered, his lips brushing against hers as he spoke. Kat smiled softly, leaning her forehead against his.

"I love you too."

With steady hands, she reached down for his belt buckle, never looking away from his face. His expression remained at ease, a glimmer of excitement in his eyes. That spurred her on, giving her the courage to open the buckle and pull it away from his trousers, letting the black leather fall to the ground. After she paused for too long, L took over, popping the button and pulling down the zipper to release him from his clothing. Kat's jaw dropped when his trousers joined the rest of their clothes on the floor. He wore no underwear. None. Nothing.

"Really, L? That's the example you're going to set for the boys? It's hard enough to dress them as it is!" She scolded, trying to look him in the eye, but every time her gaze travelled down to his length. It was much bigger than she anticipated, and that frightened her.

"It's not like they ever see me naked, so how would they know?" He reasoned, a small smile playing on his lips. He was slightly proud of the shock evident on Kat's face. Any guy would be, especially when they had pretty much no idea what they were doing.

L lead them to the bed, sitting down and pulling Kat onto his lap. Her panties played as a barrier between them, but not enough so that he couldn't feel the heat emitting from her. A small gasp escaped her lips as their hips connected, his arousal clear.

"Ohmygod." The words were released in a hurried whisper, just before she rocked her hips into his. L hissed, his hands clapping down on her hips to still her. She looked up, puzzled, but understood once she saw his strained expression. He was holding back, and it wasn't pleasant.

"You don't have to stop yourself, L, I'll be fine." She mumbled, kissing along his jaw, nibbling on his sweet spot just under his ear. His dark hair ran along her cheek, feather light and soft. It was just as wild as always, nothing unusual.

"The first time hurts for a girl, so yeah, I do. I don't want to hurt you, Kat." He stroked her back, feeling her soft skin under his fingertips. Her breasts were pressed up against his chest, and he longed to feel them in his hands, but he wouldn't act until he was sure she wanted this. He didn't care how much he wanted this, he would stop if he had to. Kat sighed, pulling back to look him dead in the eye. Determination was evident on her face, her jaw set.

"L Lawliet, don't you go soft on me. I'm not a little girl, I can handle this. If I didn't want to, I'd be in my own bed right now, not straddling your naked arse! So stop being so uptight, we agreed last time, no thinking." She was right, and L knew it. She wasn't a delicate child, but she was so small next to him... No, he had promised.

With no warning, he flipped them, laying Kat flat on the bed. Her hair fanned out around her, her lips separated in surprised lust. She was ready, no questions, no thinking.

He kissed down from her lips to her neck, then down towards the valley of her breasts. Once he reached them, he took one erect nipple in his hand, the other he engulfed in his mouth. He sucked and nibbled, gaining small moans and gasps from the writhing girl under him. It felt so much better than she had expected. She always thought people were exaggerating when they said their nipples were sensitive.

Without moving his lips, L let his hands ghost along her flat stomach, tracing the line of her panties before dipping under them. His fingers could feel the wetness gathered there, and it was an even bigger turn on to the elder boy. He moaned deep in his chest as Kat writhed. He stroked her gently while he kissed his way down to meet his fingers, moving away from her to pull down her underwear. At long last, she was completely naked. L didn't pause, his lips moving straight for her clit. They fastened themselves around the small bud, causing Kat to buck her hips up. She watched in wonder as L caused her a pleasure she had never felt before. It was almost too much to bear, too raw... Then he slid in a finger.

The single digit was like the icing on the cake. Kat could feel how tight she was, her muscles clenching around her boyfriend. A low grumbling sound escaped his throat from the feel of her, hot and tight around him, the feeling almost as good as the pleasure he was giving her. He flicked his tongue over the bud, and he couldn't believe her reaction. Her back arched, her eyes rolled back in her head, and a weak moan left her lips. Her muscles seemed to adjust to his finger, so he added another. Kat rolled her hips into his hand and face, unashamed. She was lost in the feeling, desperate for what she knew was to come, yet had never experienced.

"Oh, please, L." She whined, her voice weak and shaking. He grinned at the sound, his length getting impossibly harder. He was so desperate to be inside her, but so cautious, he wanted to give her as much pleasure as possible before the pain.

After a few more simple thrusts with his hand, L began scissoring his fingers, preparing her for the third and final finger. After three, she would be ready, and he would let her come. Her hands gripped the bedsheets, her eyes clenched shut. This was so much, it was making her mind go blank of everything other than L and the incredible feeling he caused.

"Last one baby, I promise." He whispered as he entered the final finger. She was so full, but it felt exquisite, like being massaged and stretched deliciously. L stroked the inside of her walls, feeling the muscles under the surface quiver with need. She was ready, so he would let her come.

L picked up the pace, his hand working overtime. He rose up and reattached himself to her nipple, his spare hand fondling the other. Kat moaned and whimpered under him, completely lost in his actions. So close, so close...

She exploded around him, her eyes opening to see only stars. Her body tensed and un-tensed, her mouth open in a silent cry. This was it, this was the feeling she had been waiting for.

L took full advantage of the moment, moving himself around her to position himself at her opening. Her legs either side of his, her arms laying limp at her sides, she looked up at him through the daze. He looked so strained, like he was physically fighting himself. That wasn't fair. She was so relaxed, she wanted him to feel the same. Summoning all of her strength, she reached up and placed her hand on his cheek, smiling.

"Are you sure about this? No going back?" He asked, his words filtered through his clenched teeth. Kat simply nodded, lifting her hips slightly. She wanted to give this to him, wanted him to be happy with her. It wasn't about the sex, it was about trust.

"Do it." She whispered, her strange eyes determined and sure. He could see she had made up her mind, and knew that he was good to go. Reaching over her, he pulled open his bedside cabinet, fumbling around inside until he found what he was looking for. A small, square, foil packet. He ripped the condom open with his teeth, grinning awkwardly.

"We have enough kids already, I don't think we need anymore." He joked softly, a serious undertone clear to the both of them. Kat nodded, watching curiously as he pinched the top and rolled the rubber down his length, just like Rodger had made them show him in health class. But this time it wasn't on a banana.

Condom in place, L repositioned himself, leaning over her on his elbows. He lined himself up with her slit, then connected their lips in one last kiss. Slowly, he pushed into her.

There was a slight resistance, but he made it through to the barrier of her virginity. Kat bit her lip before signalling him to carry on, her hands wrapped around his shoulders. Her eyes were closed, her cheeks red. She looked so beautiful. L took a deep breath, then pushed through, cringing as Kat cried out. The sound was soft, but enough to show the pain she felt. Why did he have to be so big?

Finally, L reached the end, fully inside her. Kat was breathing slightly harder than usual, but she held it together well. The pain was bearable, fading slowly to a dull ache. L hadn't moved a muscle for quite some time when he finally broke the silence.

"Are you alright? Do you want to stop?" He knew the answer already, but it couldn't hurt to ask. Kat opened her eyes and looked up at him, her muscles gradually relaxing around him, adjusting to him. L could feel the progression around him, the wet heat. She felt amazing, exquisite. He couldn't find enough words to describe the feeling of being buried in her.

Tentatively, Kat decided to move her hips, testing the water. She pulled back ever so slightly before pushing forward once more. L had to fight himself, forcing himself still while Kat moved on him, her brow furrowed in concentration. It was torture, but he managed.

"How does it feel?" He inquired, his tone clearly trying to hide his own discomfort. He would let her take as long as she wanted.

"I don't know... I think I'm ok for you to move now." She told him, looking down and inspecting their connection as only she could: with blatant curiosity and a hint of wonder.

L took her on her word, pulling back painfully slowly before easing back in. Once, twice, three times. She appears fine, even as though she found pleasure in the act, so he picked up the pace. He didn't necessarily go harder, just faster, the tempo picking up. He couldn't hold back the moans that left his throat, of the shudders that ran up his spine. She was so tight, so warm... Unlike anything he had ever felt before. When he finally heard a soft whine leave Kat, he relaxed. She was panting, lost in the feeling once more. The pleasure was quickly building like before, but somehow this was better. She felt fuller, more complete. She twisted her hands into his hair, pulling him down into a kiss that had them lost for breath. Their tongues danced in a way only they could describe, their bodies a mass of pure energy and pleasure.

Kat could feel her release getting close, and L want far behind her. She pushed back when he thrust forward, making their connection faster and harder. So close, so close...

Kat felt herself fall apart around him as L cried out, his back arching into her as she gasped for breath. The intensity of the moment was so thick it was almost visible in the air around them, their sweat slicked bodies collapsing onto each other. Kat felt her arms wrap around his back, his head snuggling into her shoulder. Both sated, both exhausted. L rolled off her, pulling out as he did so. He removed the condom and tied it at the end before throwing it into a small bin beside his desk. He would have cheered at the shot if he had the energy. Kat curled into his side as he laid in the bed, his arm wrapping protectively around her, his hand falling to rest on her hip. They were both flushed, both breathless, and almost stunned by what they had just done. After so many years as friends, then becoming more, they had finally done it, finally made love.

L planted a kiss on the top of her head as it rested on his chest, a welcomed weight.

"How do you feel?" He asked after a moment of just embracing the bliss. Kat smiled, drawing shapes with her finger on his chest. She didn't think about her answer.

"I feel heavy, like all of my muscles are tired. I'll be sore in the morning, but it was worth it. I could be sore for a year and it would have been worth it." L chucked softly, relieved.

"So it was good for you too? That nice to know." He watched her roll her magical eyes, a glimmer of something he couldn't identify in them. Was it pride? Or just pure satisfaction? Either was good enough for him.

"L, you really are something, you know that?" She joked, looking up at his face. He smiled sweetly, showing teeth, which was rare.

"I know. So are you, that why you love me, and I love you."

She snuggled into his side once more, getting comfortable before closing her eyes.

"I know that."
