Summary: One little action is misunderstood and your temper won't let the insult lie.

Brushing your hair back from your face, you studied the room around you and couldn't help a smile. It had taken effort and time, but you'd finally managed to get it perfect. Thorin had said he didn't care about his personal rooms, wanting to focus instead on rebuilding the mountain. You didn't fault him that and had taken this on as a personal project.

You hadn't taken any of the dwarves he needed for Erebor, instead finding a few who were willing to work a little more to help you. It had been slow going because of how infrequently you had help, but Thorin didn't mind. Or rather, he didn't notice. You weren't insulted, he had a lot to think about between restoring Erebor and his slowly recovering nephews. You weren't sure he had fully healed before he had started working, but he did collapse in exhaustion every night and you wondered if all of it was caused by his duties.

But you didn't comment on it. You weren't going to fight him on it. Not yet, but soon the King Under the Mountain was going to get the sharp side of your temper if he didn't rest properly. He was no use to anyone if he worked himself into the stone.

"Looks good."

You half turned to smile at the worker still in the room. "It does but I can't take all the credit for it," you said, your smile growing.

"We just did the building; you had the plans all figured out."

That was true, but a plan was just that without someone to build it. The crew that had helped you was kind enough, but they were also highly flirtatious. Normally, you wouldn't encourage it. You knew how Thorin felt about you, knew how he reacted when another male showed interest. More importantly, you knew how it would end. Yet in the past week, you hadn't rebuked them when they had flirted.

Even though you knew why he was busy, a part of you resented the fact that Erebor got all of your lover's attention. Was it too much to ask for a private dinner or even five minutes alone with him? Apparently it was because besides his initial greeting you had barely seen him in the past month and you were growing lonely.

That didn't mean you were going to do something stupid. You weren't an idiot, but this harmless flirting helped with the loneliness.

"Everything alright?"

You glanced at the worker. "Of course."

"Really? Don't think we haven't noticed how you get when you think we aren't looking. You can't hide that kind of sadness for long."

You frowned slightly. How much were they watching you to see that? Maybe you'd let the flirting go on for too long. It certainly hadn't felt like it had been an issue, but then again maybe you'd been blind to it because of Thorin and your relationship with him. You hadn't been serious, but perhaps they hadn't caught that.

"It's a shame really," he continued. "You're wasted just drifting around these rooms."

Oh, damn. This was really not good. "I appreciate your concern and your hard work, but I am fine," you said firmly.

"Aye, you are."

You almost rolled your eyes. Had he really just said that? That was something you expected from an inexperienced youth, not an adult male. "Your work here is done. Thank you," you said in dismissal.

His head tipped to the side. "You don't have to worry. I know how to be discrete."

Staring, you took a step back. "You need to leave."

He smiled. "But you'll come with me, won't you? You've sure acted like you would."

You swallowed hard and took another step back. Before you could dismiss him again, you heard a low noise that chilled you to the bone. Wide eyes barely saw the dark blur that came from the bedroom door and slammed into the worker. "Thorin!" you gasped as he pinned the other to the wall by his throat.

"Leave," he snarled at the male, "and never let me see your face again."

Thorin tossed him toward the door and you watched as the worker scrambled out. You expected him to turn to you once the door was closed, but he kept his back to you. His shoulders were heaving and you could hear the air hissing out of him, a clear sign his anger was soaring.

What was he doing here? It was midday and he only returned later at night, sometimes after you'd gone to bed. Why had he come home early today?

"How long?"

You shivered at how deep and furious his voice was. "What do you mean?"

"How long has this been going on?" he demanded harshly.

Confusion filled you. Something was wrong. "I'm not sure what you're referring to," you said carefully.

A low hiss left him before he rounded on you.

You smacked into the wall as he came toward you, the fury on his face honestly scaring you. You couldn't help your legs shaking when his hands slammed down on either side of your head. "Thorin, tell me," you whispered.

"I spend all day struggling to rebuild our home," he spat, "away from you and where I actually want to be. In the month you've been here, is this how you spend the time I'm away? By flirting with males you've brought to our rooms?!"

Your eyes widened even as his accusation hit you like a fist in the gut. Yes, you'd flirted a little, but nothing to warrant this treatment. "Thorin, I would never betray you," you said softly. "I love you."

His blue eyes were so pale and spitting mad. "How many have you had in here?"

"They've only worked on the rooms!" you insisted. "I've never done anything like that!"

He didn't look convinced. "You've been alone for a long time," he said lowly. "First when I left for Erebor, your journey here and now the past month."

You stared at him, hurt beyond measure but you could feel your own temper sparking to life. It was hard to choke it down but you knew that a clash of tempers right now would end only in a vicious argument. "Thorin, I love you," you said quietly but firmly. "I have only and will only be yours."

Thorin pulled away from you, eyes narrow. "Prove it," he said flatly.

You blinked. "What?"

"I left early today to spend time with my lover and I found you flirting with a worker. You say you love me, are loyal to me. Prove it," he growled.

"How?" you breathed.

"If you really love me, you'll figure it out," he snapped, stalking into the bedroom.

You stared at the open door, shock filling you but it quickly gave way to rage. Prove you loved him? Prove you loved him?! All you had ever done was love his sour, grumpy, miserable hide for as long as you could remember and this is what came of it? You had spent the past month wondering when you would get to see him and this is what he did?

Your hands curled into fists. The arrogant, pompous ass! Yes, you had flirted a little, but you had never crossed any lines. Today was the first time one of the workers had ever gone further and it wasn't something that you were even encouraging. Of course it had to be the one time he came home early and he hadn't seen it properly.

Eyes narrowing as you kept looking at the door. He thought you didn't love him? Pretentious bastard! Oh, you would show him that you loved him, show him how you had kept your sanity while he had ignored you and he would be lucky if he survived it.

Prowling to the door, you saw he had stripped off his tunic and had his back to you. You fought the urge to growl and slammed the door behind you. He barely reacted, mildly looking at you over his shoulder and it sent your temper soaring.

"Prove I love you?" you repeated sharply.

Thorin arched a brow, his eyes still angry but he didn't say anything.

"I have spent decades loving your grumpy ass," you growled, "and you dare accuse me of not loving you?!"

"Grumpy-"

"No!" you snapped. "You've said more than enough! Speak again and I will leave this room right now and you will have a hard time of convincing me to ever come back!"

He glared at you, but his mouth stayed closed.

Walking to him, you gave him a hard shove. You watched as he bounced on the mattress and made to get up. "Stay put!"

A deep growl rumbled out of him, his eyes ice blue as his own anger came back.

"I'm supposed to show you I love you?" you threw at him. "How can I do that if you don't stay still?"

He stared at you for a long moment before slowly leaning back against the mattress. Angry eyes watched you, but that wasn't the only emotion making them burn now.

Taking a deep breath, you briefly considered tying him to the bed frame. You doubted he would stay still long enough for that, but the idea was tempting. Another breath calmed you a little further and you realised you had no idea how to prove you loved him. You had thought what you did for him would have been enough, but it hadn't stood up in the face of one dwarf flirting with you.

That made your temper spark again and you knew what you had to do. "Do you even know how painful it is to be alone for any length of time? To know the one you love isn't near?" you growled. "Do you know how frustrating it is to be denied the sexual gratification you've grown used to?"

A low noise left him and you saw his expression tighten. Yes, he did know but you didn't soften.

"I didn't turn to others in your absences. It never even crossed my mind."

"Then what did you turn to?" he asked lowly.

Reaching behind you, you gave the laces of your dress a tug. Once the material was loose enough, you shrugged out of it. "The same thing I have always done when you aren't near," you said as your dress pooled at your feet.

His eyes got a little darker as you stood naked before him and a harsh curse slipped from his lips when you wiggled your fingers at him. "Mahal," he groaned. "You still…?"

"Of course I do," you said in disbelief. "I'd go mad if I didn't since the mountain consumes you and I miss when you used to be like that with me."

Thorin growled your name and pushed himself up so he was sitting.

"Stay there," you warned him, stepping back.

He didn't say anything but you knew he didn't like it.

Glancing behind you, you saw a wide chair and knew where this was going to lead. You sank into it and crossed your legs so he could only see your upper half. Reaching up, you pulled all of your hair away from your face, arching your back as you did it. You could feel his eyes on you, your nipples tightening under his gaze.

You let your fingers trail down your neck, feeling chills break out on your skin at the touch. It had been a while since you had done this and you had never done it when he was nearby. Why would you when he was available?

"Tell me," he said roughly.

"Tell you what?" you asked, your fingers stilling at your collar bone.

"What you think when you do this."

Your brows lifted. Was he honestly going to test your love this much? "What do you want me to say?" you asked, slowly stroking along your collar. "That I think about you when I pleasure myself?"

"Do you?" he rasped.

"Of course," you purred. "Nothing else works for me."

He shuddered harshly, licking his lips as his gaze moved over you.

Letting your touch trail down to your breasts, you stroked over the soft skin. As your fingers grazed your nipples, you murmured, "I think about when you take me in your mouth and ring my nipples with your tongue. Makes me ache to imagine you sucking on them."

Thorin growled lowly, watching as your fingertips skimmed around the hardening buds. "You taste too good," he rumbled. "I can't help myself."

"Oh, I've noticed," you breathed, making yourself gasp as you pinched them. "And when you bite me? Mm, Thorin, it feels so good."

He rubbed a hand over his mouth, a soft hiss leaving him as your back arched again.

Cupping your breasts, your thumbs flicked back and forth over your nipples. As convincing as your imagination was, you were having a hard time pretending it was him when he was sitting right there. You wanted his hands and mouth on you. But you were supposed to be showing him how much you loved him, how you hadn't cheated on him. Tipping your head back into the chair as you rolled your nipples between your fingers, you tried not to squirm as heat pooled between your thighs.

You forced your hands to move down. "But you never stay at my breasts, even though you could probably make me come if you did."

His brows rose. "I'll keep that in mind for next time," he said softly.

You hoped he did. Your fingers feathered over your ribs as you thought about how he would kiss down them, his beard rasping against your skin deliciously. He always nipped at the soft skin under your navel before he moved lower, teeth scraping over you. Just thinking about it made your arousal spike.

You don't stop there," Thorin growled. "I know you don't stop there."

No, you didn't. You ran your hands along the tops of your thighs and slowly uncrossed them. You weren't surprised when his eyes fell to what you had just exposed and you spread your legs a little more.

"Is this your favourite part?"

"I'm not telling," you breathed, lightly dragging your nails up the inside of your thighs. "But I love thinking about your tongue running over me, licking me slowly like we have all the time in the world. Your hands slide up my legs, thumbs parting me so you can, ah, suck on my clit." Your voice faltered as your fingers moved over your clit, sparks of pleasure shooting through you.

You heard a ragged noise leave Thorin and you glanced at him. Eyes widening, your breath caught as you saw his fist was curled around his cock and he was pumping it hard. "Keep going," he ordered.

Shuddering, you rubbed a little harder at your clit, savouring the little bursts of heat that exploded under your skin in response. "I love it when you're slow," you whispered, "but my favourite part is when you shove me on my back and make me scream, when we haven't seen each other in a while and it feels like you'll die if you don't have me."

He groaned deeply, his body shaking in response to what you were doing.

"When you slip your fingers inside me, Thorin, I…Mahal, I want to come just thinking about your hands and your mouth on me," you panted.

"No," he growled.

You stared at him, shocked. If he denied you this now, you'd kill him. You would honestly murder him. "Thorin?"

He shook his head. "You aren't going to use a thought when I'm right here."

Trembles coursed through you at the thought of having him, but you weren't sure about it. "Have I proved it?"

His eyes darkened. "Come here."

"Have I proved it?" you repeated, not moving.

He growled darkly. "Aye, I know you love me."

"Arrogant ass," you whispered, bracing your hands on the arms of the chair. You ignored his second growl as your legs wobbled when you stood up. Taking a steadying breath, you threw caution to the wind.

Thorin grunted as you hurried to him, nearly leaping into his arms as you straddled his lap. His hands landed heavily on your ass, squeezing you as you rocked against him. "Take me."

You shook your head, enjoying the feel of him between your legs. He was so hot and hard….

"Take me," he repeated, "or I'll take you."

What an appealing threat, but you wanted to still be in control. You reached down to grasp him, unable to resist sliding your hand along his erection. He shuddered under you, hands flexing on your ass.

You let him lift you just enough so you could move him to your entrance. Raising your gaze to his, you smiled when you saw how dark his eyes had become. These were the eyes of your lover, not the tyrant from earlier. So you let him go and dropped your hips on him.

Moans left both of you as he filled you and you had to bite your lip as you realised how close to orgasm you were. Looping your arms around his neck, you braced your knees firmly on the bed and began to ride him. You felt like you were on fire as your breasts rubbed against his chest, your sensitive nipples dragging over his muscles and arousing you further. "Thorin," you whispered, head tipping back as he began kissing your neck and shoulders.

A deep purr left him and he rubbed his beard against you.

Your muscles tightened at that. You loved the feel of that coarse hair on your skin, loved when he was close enough to you to do it. Your hands curled into fists against his back and you moved harder on him.

One of his hands slid up your back, tangling in your hair. You expected him to tug your head back so he'd have greater access to your neck. Instead, he tipped you forward and claimed your mouth.

Groaning raggedly, you were glad when he wrapped his arm around your waist and helped you moved. His fingers were digging into your hip, but you didn't care. His tongue was curling around yours, rubbing and stroking you. His cock was moving deep inside you, making you tremble as he pushed you closer to release.

You broke the kiss with a whimper, your body tightening as pleasure coiled within you. It wouldn't take much more. Just a little-

"Come for me," he growled against your throat.

Your breath caught.

He made a low noise as you resisted. "Come for me."

Your pleasure cracked before shattering at his rough words. Crying out, you shuddered in his arms, your body jerking as your climax washed through you. Stars exploded under your skin, desire and pleasure filling you.

Thorin kept you moving, his lips firm on your neck as he sought his own end. His harsh groan as he thrust hard into you made chills dance over your skin. His arms tightened around you, holding you close to him.

You felt his breath striking your skin before the world spun as he turned you both so he could press you into the mattress. Your head was resting on the pillows and he was a warm weight on top of you. "Thorin," you whispered when you found your voice.

"Mm?"

"Don't doubt me again," you growled. "I won't be so nice next time."

There was a moment of silence before he chuckled deeply. "Aye, love."

A/N: Well! That didn't go as planned but this is better than what I'd originally had planned. This just kind of happened but nothing wrong with that, right? Special thanks to a friend who let me ramble about the idea and then helped flesh it out. You know who you are! And thank you to everyone who reads this! Love you all!
