Heat of the Moment

Summary:

It was dangerous for an omega to leave the shire. Bilbo had been warned of that many times in his life, but no one had prepared him for what would happen if he was kicked out his front door by a wizard on a power trip without packing any suppressants. He had gotten lucky up until this point. His heats weren't frequent now that he was a few decades past his majority. Luck had to run out eventually.

This is an oh no, I'm going into an unexpected heat story. A popular trope that I frankly could read 1000 times.

TW: Contains an almost non-con situation.

     It was dangerous for an omega to leave the shire. Bilbo had been warned of that many times in his life, but no one had prepared him for what would happen if he was kicked out his front door by a wizard on a power trip without packing any suppressants. He had gotten lucky up until this point. His heats weren't frequent now that he was a few decades past his majority. Luck had to run out eventually. It was the river that caused all of this. The adrenaline, combined with the fear of drowning, triggered his system into trying to find an alpha to keep him safe. His body had betrayed him, and it was only a matter of time before it became a problem that could potentially jeopardize the quest. He was not so naive to think Thorin would stay their march just for him, nor did he dare hope that a future king would lower himself to taking a hobbit. He would be just as likely to leave him behind.

Bilbo paced the small washroom of Bard's home, wracking his brain. If he could find a place to hide, he would only need three days. It almost always passed within three days. Bilbo put his head in his hands. It would be three days of agony. Heats were not meant to be passed. They were meant to be sated. It was like an ich at your very core that was begging with everything it had to be scratched. It was not uncommon for an omega on day three of being unattended to beg to be taken by whoever would listen. It's part of what made heats so dangerous. That and the fact that an omega was never more tempting than in a heat. The smell alone could send an alpha into a full-blown rut that scrambled their minds and set them to pure instinct.

He had a day at most to slip away. Bilbo stepped out of the bathroom more sure of a plan now than before, even if it wasn't one of his best. His thoughts were so occupied that he ran directly into Thorin on the way to the kitchen.

"I wondered where you had gone. You shouldn't stray while here. These people are dangerous." Thorin ushered him into the kitchen with a hand on his back.

"I was using the restroom. I hardly call that straying," Bilbo replied dismissively. Thorin turned to him, bent closer to speak in hushed tones.

"I do not trust these men, and I do not trust their hospitality. Some look at us with curiosity, but many more with distrust. I especially don't like how some look at you." A bit of that signature alpha protectiveness was laced in his words, and it made Bilbo smile. This was precisely what made Thorin such a good leader.

"I'm sure it will come to nothing. How long are we staying in Laketown?" Bilbo asked.

"Five days. Less if we can gather resources quick enough." Thorin replied. Good Bilbo thought. It would mean everyone would be too busy to notice he was gone for a few days. Bilbo nodded to Thorin and walked out onto the back dock of the house. He had remembered seeing abandoned fishing shacks on their way in. They were out of the way, and the breeze from the water would push his smell in the opposite direction of Laketown. He should be safe enough if he could make it to one of those.

He spent the rest of the day gathering supplies and building a pack. When he felt his nesting instinct starting to kick in, it was a clear sign that he needed to move fast. The only thing that he wouldn't have would be much food. It wouldn't make this process any easier as any omega, but especially hobbits, burn a ridiculous amount of energy in a heat, let alone trying to suppress one. As soon as the sun set and the company turned in for the night, he slipped quietly away. No one heard or saw him as he made his way through the streets.

He arrived at the two-room shack, and In an hour, he had constructed something akin to a bed or sleeping platform in the second room. He wasn't pleased even after pushing some empty barrels over to bracket it. The ceiling was too high, and he didn't bring enough blankets to make any kind of makeshift tent. He threw a fishing line over the top, curled into the blankets, and drifted to sleep.

When he woke, it was like someone had set fire to his body. His senses were wild and fully alert. There was a stark emptiness that threatened to consume him. He sat up and ate some of his rations before curling back in on himself. He wanted so badly to spend one of his heats with someone. With anyone, but especially with Thorin. Even if he didn't claim him just to finally feel that fullness that other omega talked about. Would Thorin be gentle with him? Caresses and whispered affection or kisses in his hair while he held him. Or would he be as primal and feral as his usual disposition led you to believe? Would it be rough hands in his hair, teeth on his skin, and bruising force? What did it say about Bilbo that he didn't care, which it was if it meant that it would Thorin's hands on him at all?

The next phase of his heat washed over him. Even he could smell the strength of his pheromones, and he prayed to Yavanna that the pungent smell of fish was enough to drown it out. The need in him grew tenfold. His clothes became uncomfortable, almost unbearable on his skin. He stripped to his base layers and tried to bring himself some relief. His hand was on his cock already, but it just wasn't enough. His body was already producing slick and trying to prepare itself for an alpha. He needed something in him, and his fingers would have to suffice. They were a poor substitute, and he still felt hollow even after finishing.

He was eating and trying to navigate the waves of arousal when he heard noises and voices outside of the shack. Temporarily, he couldn't feel his need anymore. He could only hear the beating of his own heart. The voices clearly belonged to men, and they were drawing ever nearer. If they came in, he would be stuck. There was no second point of egress in this shack, and he had left the ring with the rest of his things in Bard's home. He was dressed in barely anything at all. He lay flat under the blanket as still as he could and covered his mouth. The door opened.

"The bloody hell is all this? I get a vagabond in here or something?" The first man grouched. Someone shoved the man, and he skittered into a group of fishing pols.

"Fucking idiot beta. There's a ripe little omega in here. You could smell them just from outside." It would be obvious where he was the moment he rounded the corner, but his body couldnt move. The smell now mingling with his in the space was pure alpha very near to a rut. Bilbo's fear pinned him to the spot until the shadow of the man stepped into the doorway. "There you are." said the man. "I've never seen one like you before. You're not human. You're not pretty enough to be an elf, and you're not stocky enough to be a dwarf. You are clearly an omega." He walked forward until he was an arm's length away. Bilbo regained some of his voice.

"I'm a hobbit, and you're intruding here. I won't be but another two days. Leave me in peace." Bilbo's voice was shakier than he wanted it to be. Likely because this alpha was leaching pheromones.

"Why would I leave you all alone and defenseless? You're clearly in need, and I am fully equipped to help you." The man reached in to drag him out, and Bilbo scrambled away. "Don't be like that. I know it must be incredibly painful. I can see how hard your little cock is through your pants." This time, the alpha lunged and caught him by the leg. He dragged him back and pinned him to the floor. "If you keep struggling, this will only be harder for you." There was nothing Bilbo could do. This man was twice his strength. He felt himself get manhandled onto his stomach as the human draped himself over him and roughly pulled down his pants."I'll try not to knot you. No promises, though." Bilbo shouted and struggled again before gritting his teeth at the inevitable.

A snarl of something in a language he didn't know ripped through the air and the pressure on his back was wrenched away from him. Bilbo immediately scrambled to the furthest corner the moment he was free.

Thorin Oakenshield was standing like the angel of death over the human man on his knees. His hair was wild, and his expression was darker than a moonless night. He held Orcrist deftly in one hand, but it was not pointing at the human, nor did it need to. There was so much charged alpha energy in the room that had he not been in heat already; he would have been shortly thereafter. The human was cowering in the face of his betters.

"Dori. I don't want to sully Bilbo's nest. Take this man outside, slit his throat, and throw him in the river." Dori dragged the man out screaming, and Thorin turned his attention to him. Bilbo didn't know whether to cower or submit.

"Th-Thorin, I'm sorry! I thought that you would all be too busy to look for me. I thought I had this planned out better." Bilbo babbled as Thorin walked closer. When he reached Bilbo, he crouched to be closer to his eye level. His voice was soft, and all the anger from before seemed gone.

"Did he hurt you? Was I too late?" The question caught Bilbo off guard.

"No, he didn't get the chance," Bilbo breathed.

"When I woke and could not find you, I worried and set the company to look. Bilbo, why did you not tell me you were going into heat? I could have found you somewhere safer to nest properly. I could have hel-" Thorin stopped his next words short and let the sentence hang. When Bilbo said nothing, Thorin stood and looked around. "This can't be comfortable, but I don't want to move you smelling as you do. I'll bring you more blankets and better things to nest with. What did you bring for food?" Thorin spotted his pack before he could say anything. When he opened it, he looked up sharply. "This is all you brought to last an entire heat?" He sounded shocked and a little horrified.

"It's only three days, and I didn't want to take food out of the company's hands." Bilbo pulled the bag from Thorin's hand and set it back down. Being this close to Thorin was agony. His body was responding to him too much, and he had to lean against the wall not to buckle. "You should leave Thorin. Please. You have to prepare for the trek up the mountain, and I don't want to slow you down." Bilbo's legs really did give out that time, and Thorin's hands darted out, but he did not catch him. He knew why. Even as strong as he was, being here must be in and of itself uncomfortable. Even if Thorin did not normally desire him, this call was instinctual.

"I will stand guard then and ensure you are undisturbed," Thorn said. Bilbo couldn't let him do that. If Thorin were so near, so close on the third day, it would drive him to madness. He would debase himself and beg for Thorin to take him.

"No! No, please leave me here. I don't think anyone else will come, please." Bilbo begged. Thorin looked angry again.

"Leave you to nearly be taken against your will again! Do you have a death wish? You think I could leave you unguarded after what I nearly witnessed?!"

"You have to!" Bilbo urged

"Do you fear that I might lose control of myself? I won't. I am not controlled by my ruts, and I won't touch you without permission." Thorin vowed.

"No, it's because of me! Because if you don't leave, I will beg you to take me! Because I care for you deeply, and being alone and in heat is so painful, and I want you to take that pain away, but I can't let you do that to yourself! I can't look at the shame on your face when you come out of this and realize that you lowered yourself to bedding a hobbit. I can't continue on this quest knowing that even if I was yours for a night, I can't be yours forever!" Bilbo was crying now. He staggered to his feet so that he could walk to his nest and collapse. He felt more empty now than he had before. Perhaps he would ask Thorin to bring him a pillow just so he had something to rut against and hold. Thorin had not moved. He stood there with his hand flexing at his side. Like a wooden doll coming to life, he finally moved again and headed for the door. It was for the best, Bilbo reminded himself. He heard murmurs in the other room and the sound of many people shuffling out.

Bilbo bunched his fists into his eyes and started to cry in earnest.

"I'll have none of that now." Thorin's voice whispered near him. Bilbo looked up to see that Thorin was back. He had shrugged off his heavy layers and was in just a tunic and loose pants. He brought with him his coat that he offered to Bilbo like a token. "The others will bring more, but this is warmer than what's around you." When Bilbo had taken it, a warm hand caressed the side of his face, and Bilbo whimpered on contact.

"T-Thorin..."

"Do you want me to join you, Bilbo?" Thorin asked gently.

"Yes, but you can't. You don't really want to. It's just because I'm in heat." Bilbo couldn't take this. He was so close it was like torture.

"It's not your heat, Bilbo. This heat is not what has made me dream of you for months of our journey; it is not what has kept me alert to your every need. I want this." Thorin was in his nest now, his other hand guiding his hips into laying down.

"My heats always hurt so much." Bilbo hiccuped as he let himself be led.

"They don't have to. They never have to again." Thorin's lips met his, and the sensations of the world opened up to him. Warm hands, the scratch of a beard, and the hardness of Thorin's body above him. It was electricity. All the ache was turned to a purpose, and he melted into Thorin's touch. Thorin wasn't rough at all. He was gentle, reverently so. He ran his fingers through Bilbo's hair and slowly undid the lacing on his shirt so he could tug it over his head.

"I've wondered since meeting you what your skin would taste like. When I saw the hint of the freckles across your shoulders when you would lie sleeping in your bedroll. On nights when I wondered how wicked it would be to hide your nightshirt in hopes it would force you to sleep without one." Thorin mapped the freckles across his shoulders and on his chest with kisses, stopping to occasionally nip and draw out surprised moans. The rest of their clothes went quickly until both of them were bare. Thorin's body was a marvel. His arms were rippled with muscles developed over a century of blacksmithing and swordsmanship. Bilbo felt rather plain by comparison.

"Would you rather me turn over?" Bilbo offered. Thorin would likely enjoy that view far more, he thought to himself. He started to do just that before his arms got pinned on either side of his head.

"Don't you dare. I intend on taking you just like this, where I can see all of you right up until I knot you." Thorin's voice was raspier now, and Bilbo could feel the tip of his heavy cock resting on his stomach. Bilbo was dripping in anticipation, his body ready, waiting, and impatient for it. He felt his body open even more at the thought of Thorin knotting him. Linking them together and creating that bond. Would he bite him, too? Choose him as a mate for all to see? "I don't even think I'll need to open you up." Thorin's fingers glided over his entrance and pushed in. Bilbo gasped and twisted, trying to get them to go deeper. It made Thorin chuckle as he started scissoring them inside him.

"I'm open enough. Please." Bilbo wanted it; he needed it. He needed to have Thorin inside of him right now, or he was going to burn up." Thorin grabbed his hips and slid his forward, then pushed into him. Bilbo thought he might scream, but he could only cry and moan in relief. There was so much of Thorin and a good burn but no pain to accompany what he was taking. Thorin growled above him, grip still surprisingly tender. He bent over Bilbo and kissed him thoroughly, letting his thumb linger over his lips ever after he sat back up. Thorin didn't have the patience to wait long after he was fully seated.

"You have no idea how much I longed for this. How many nights I spent with myself in hand thinking about what it might be like to be in you, even for a moment." Thorin had his hips elevated and was pounding every inch of his cock into him. It brushed over the sensitive parts of him, making him nearly scream with the pleasure of it. He felt safe and comfortable as the void got smaller and smaller. "All your curves and softness just teasing me, begging me to bury myself in you again and again until you grow round with my child." Bilbo's body responded to that thought immediately by bearing down on Thorin and growing tighter, almost in invitation. Thorin grunted and wrapped his hand around Bilbo's cock. It took barely three pumps before he came on his stomach. Even after he did, he was still hard and leaking.

"I want that Thorin. I want to be your omega and carry your heirs and live in your mountain!" The next sensation was sharp enough to dull the pleasure he was feeling. Thorin sunk his teeth hard into the side of Bilbo's neck and broke the skin. His shout of pain was immediately followed by soft touches as Thorin licked and kissed the site of his new mark. He had been bitten. An alpha had claimed him as a life mate in the middle of a heat. He came again with a cry of ecstasy as he nuzzled Thorin's neck, nipping at the place he wanted his mark to go.

"Do it, Bilbo. Please. I want to be yours as much as you mine. Stake your claim in me." Thorin panted. Bilbo kissed the spot, then bit down hard until he felt the skin break and the taste of iron on his tongue. Thorin roared, and his thrusts faltered. He left Bilbo's body and began urging him onto his stomach. He wasted no time sinking back into him. With a kiss to the back of the neck, Thorin whispered, "I am going to knot you, and then I am never going to let you leave my side until the day I die." It was not said with command or with possessive grit. It was said with overwhelming love and affection.

Bilbo felt the knot push into him, and at long last, the void that had only grown wider all his life vanished for good.
