Chapter Text
Zuko hadn't been back in the palace for long, maybe a few hours, before his father called for him. He was worried. He had presented as an omega during his banishment and although he normally took suppressants and that made him smell like a beta, he had run out on the ship back to the fire nation and been unable to acquire more. He knows azula must have told his father and that ozai could not be happy about it. All he needs is to stay; he doesnt need to be in line for the throne anymore he just cant be banished again.
The guard leading zuko to his father doesnt take him to the throne room but instead a small sitting room. He opens the door for zuko and slams the door shut once zuko is through. His father sits at a tea table with a pot of tea in front of him. His fathers scent of oil and fire is soured with displeasure, it makes zuko shrink in on himself like it always has. Zuko kneels before the table and bows to the floor “my lord what is it you need.”
“It has come to my understanding that you are an omega.” his father doesnt tell him to rise so zuko stays bowing “its disgraceful to have you in line for the throne you have been taken out of the line of succession.”
“Yes my lord”
“But I do have a use for you after all.” he can hear ozai pour a cup of tea “rise and come drink.”
“Yes my lord.” zuko rises and comes over to the table taking his cup and taking a long drink from it. It tastes strangely more medicinal and earthy than a regular tea he would have with uncle. “Please firelord, what can I do to be useful.”
“You will do as you are told and help the fire nation make political ties. You will be mated to a political prisoner later today.”
“How-how will I be mated if I'm not in heat?” Zuko gasps and looks down at the tea in horror.
“Ive given you tea to send you into heat. Be a good omega and drink it.”
Zuko kept tears back as his hands shook. He drank his tea like told and wished he was banished instead.
__________________________________________________________________
Sokka didnt know what to think about his predicament. He was captured under ba sing se and taken back as a prisoner by azula and her cronies. It was kind of embarrassing to be beaten by an alpha who still has the milky pup smell still lingering but then again his sister is also an alpha with the milky pup smell and she could and would kick his ass for thinking that. He isnt sure where he is other than in a cell with no window, they had knocked him unconscious before moving him. He hears the doors outside his cell opening and light spills in from outside. Two guards open his cell and drag him out.
“Where are you taking me?” Neither would answer or even look at him. He thought of struggling but deemed it would be a waste of energy that he could use later to escape.
Sokka is dragged up a bunch of stairs and then out a side door, they open up into a large empty room. The two gaurds drag him out of the room into a hallway and he realizes distantly through his terror that hes in the royal palace. They pass a hallway full of portraits of what must be past firelords, he passes the last one and the face of ozai stares down at him, tall and imposing, he swallows thickly.
Hes pulled to a room and is slammed with the scent of an omega in heat, warm and inviting to no doubt any alpha, the soft honeysuckle and ocean scent intensified in the room. Sokka had never been in a room with an omega in heat, mostly just passing by igloos with the smell seeping out. He can feel his body relax as the omegas pheromones took hold.
The room is smaller than expected, theres a bed in the middle of the room up against the wall, a small dresser and mirror and what looks to be a built in bathroom on the side. Ozai stands next to the bed, a disgusted look upon his face as he looks up at them hes blocking the face of the omega on the bed, but he can see the o’s naked legs spread wide open. The guards bring him closer to the bed and ozai, he still cant see the omega’s face from here but he stops thinking about them the moment ozai grabs him by the neck, squeezing and heating his hand in an obviously threatening way as the guards continue to hold him.
“It seems my useless son has presented as an omega while he was away. And it seems you are the alpha son of the lord of the southern water tribe. The fire sages have deemed that i will win this war with sozins comet. So I had the idea of a political bonding. You and zuko will mate and create a child, then the southern water tribe will have to cave to my will.” Sokka gasps and tries to twist to see the person on the bed better. Ozai smiles and turns to the side to let sokka see. Aang had said after they had gotten off zukos ship the first time, that zuko was an omega, they hadnt believed him at all. Both him and katara were never able to catch a nice whiff of zuko to confirm or deny but now right here sokka has his answer. Zuko looks dazed and confused and even though sokka doesnt know much he feels like zuko has been drugged. Hes naked and limp his legs having been left wide open putting his sex on display for all to see. His tiny breast rising and falling quickly as he pants. Ozai speaks again, pulling his focus off the omegas body “I know about the invasion, its no doubt that you savages will still go about it even without the avatar. Once we defeat them and take their lord captive we will open the negotiations.”
Sokka didnt know aang was dead and despite wanting to cry he has no time, its much too dangerous to let his feelings show “Not much of a negotiation if its forced.”
“I dont expect a water rat to understand.”
This close he could see the slick forming on zukos sex “how is he even having a sexual heat hes to young.”
“The same way you will be having one, there is a tea the fire nation has found that will force a sexual heat or rut on anyone. You will be drinking it as well.” ozai pulled out a flask and handed it to him. Sokka looked down at it in panic. “You will drink it now or be forced to drink. You do not want us to force you. But it is your choice.”
It isnt much of a choice, sokka drinks deeply from the flask until it is all gone, wiping his mouth off after he finishes and handing the flask back. He can smell the satisfaction coming off of ozai and he realizes hes glad it was him who was grabbed and not his sister. “Now what?”
“You will be left alone. I will have a beta come and deliver food when needed and there will be two guards outside the door. I expect to see a mating mark and a pregnancy soon. Do try not to disappoint.” Ozai turns and walks away, the two guards also letting him go and following.
He can smell his rut coming on quickly, his body heating and his cock beginning to swell. He can smell his own self as his scent of sandalwood and pine fill the room. Zuko takes a shuddering breath and slides a hand down to his cunt and began to finger himself. sokka quickly walks to a corner and pretends he cant hear zukos soft moans. He feels bad about what is about to happen. Hes sure zuko isnt ok with it either but also has no choice in this matter.
Sokka isnt sure how long he last for but eventually the smell of slick and heat has him groaning with need. He wants to start this semi-level headed so he doesnt hurt zuko. He walks to the bed and begins to strip, climbing up and laying next to zuko on the bed. He gently took zukos hand away from his groin. “Zuko? Are you there?”
Zukos eyes slowly focused, he turned a confused face over to him. “I know you, your sokka? You're with the avatar.”
“Yeah thats me.” zukos hand begins to move back to his crotch and sokka grabs it and stops it.
“Why are you here? Are you the one I have to mate? Or did I go with you guys? I wanted to go with you but I got scared.”
Sokka shushes him “you're in heat, i'm here to help you through it.”
“Why does it feel like this, it shouldnt feel like this.” sokka growls when he smells the distress coming from zuko
“Shhhhh its ok you went into your first sexual heat early, i did too. Were gonna help each other ok, the firelord said so. Your dad said so, you're ok ill take care of you ok.” Sokka tries to keep his scent sweet, keeping the distress away. Zukos scent calms and zuko nods. “Ok, I'm gonna help you. Can I touch you?”
“Please help me.”
“Right” sokka runs a hand down from zukos arm to his chest and stomach. Gently laying a hand over zukos sex, gently rubbing at his folds. Zuko groans and opens his legs impossibly wider. Sokka thinks for only a second before shoving his face inbetween zukos shoulder and neck right at his scent glands. Right where he has to bite him to mate. He takes deep whiffs to calm himself before kissing down to zukos chest, taking a nipple in his mouth and sucking softly. Zuko keens and grabs at sokkas hair pulling the tie out of it distantly sokka can feel it fall down onto the bed.
Sokka continues his way down zukos body till his face is at his crotch. He takes another deep breath filling his lungs with the scent of the omega. He removes his hands and instead gives a testing lick to zukos sex. Hes eaten out suki before just once after the serpents pass and the babys birth but suki had been a beta and he was unsure how much their bodys differ. Suki had mentioned that sokkas body differed from beta men, who had no knot or rut to see of. Zukos privates looked differently than hers did, his clit was enlarged about an inch long his body more masculine, more boxy with broader shoulders and smaller breast. Zuko’s taste was more acidic, almost sour in taste and distinctly sharp on his tongue. He can still smell zukos honeysuckle and ocean scent from here but his slick is musky in the best way. He gives more and broader licks before dipping inside.
Zuko moans loudly, thighs closing tightly against sokkas head as he licks his inner lips. Sokka wraps his arms around zukos thighs and gently pulls them back open. He moves up and gently licks at his clit, just small circles with his tounge slipping it under the hood. He wanted to see if zuko would like it, suki said not all liked having this area touched. Zuko gasped and arched his back, grabbing at sokkas hair clumsily. Sokka took it as he liked it and decided to go farther, he took zukos clit into his mouth and sucked softly, zuko screamed so loudly he was sure the guards outside could hear.
Hes never put his fingers inside of suki but he has to get zuko ready to take him so he experimentally sticks his index finger inside. Zuko is loose and open so sokkas finger slides in easily he sticks another in as well, its tighter and he hears zuko let out a small grunt at the stretch. He gently hooks his fingers he feels a small rough patch inside and when he rubs it zuko pulls his hair as he moans. He continues to rub that spot and suck his clit and he can feel zuko clench down hard on his fingers and gush fluids down his chin.
He keeps sucking until zuko begs “stop please.”
Sokka sat up and slowly took his fingers out rubbing them on the bed to clean them off then wiping his face off with the edge of the blanket. He climbed up and laid half on top of zuko, unintentionally rubbing himself off on zukos hip. “Are you doing ok?”
Zuko looked at him dazed “you ask stupid questions.”
“Oh im sorry im worried about how your doing”
Zuko smiled “No no keep asking your stupid questions”
Sokka smiled too “ok then how are you doing?”
“I hurt down there, but what you were doing made it feel better. I think I need to get off again. But im feeling clearer headed than i have been. How are you doing?”
“I still feel clear headed but i dont think its gonna stay that way for long. Are you up to go farther?”
“Please”
Sokka nods and hoist himself up he spreads zukos legs again and settles between them. He lookd down at himself, his knot already swelling and then looks at zuko “do we have anything to make this go easier? Like oil or something?”
“We dont.” sokka hums. He rubs himself over zukos folds covering himself in slick before slowly entering zuko. Zuko gasp and grabs at sokka before sokka gets the gist of what he wants and leans down covering zuko. He wraps his arms around sokkas shoulder and buries his head in sokkas scent glands. Sokka begins to purr to calm the omega in his arms as he bottoms out.
He stops moving and lets zuko adjust. Eventually zuko mumbles “you can move.”
Sokka starts slow and worms a hand down to zukos clit to rub it. Eventually the glide gets easier and zukos sounds get louder. “Can I kiss you?”
“Yes, yes, yes!” sokka leans down and kisses him starting simple before swiping his tongue across zukos lip. Zuko opens his mouth and the two make out. Zuko lets out a particularly loud cry against his lips as he cums again.
Sokka slows down a bit “you still good to keep going?”
Zuko looks blissed out as tears begin to fall and he bables “please please dont stop im so close dont stop.”
Sokka kisses the corner of his mouth and shushes him again “i wont stop your ok i wont.”
Sokka is slowly losing control he can feel his knot forming and his orgasm coming quickly he goes back to rubbing quickly at zukos clit. With one final push his knot forms and sokka leans down and bites zukos scent glands and cums. Distantly he can feel zuko cumming again. He holds the bite till he feels zuko untense. His scent has already started to change to honeysuckle and ocean with a hint of pine, distantly he can smell the ocean on himself. Zuko begins to purr deeply. Eyes closed, face and body loose and relaxed. He licks at the bite, not able to talk just yet.
After a few minutes the door is opened and sokka lets out a loud growl. There in a dangerous situation fully exposed with sokkas knot firmly still lodged in zukos cunt he cant protect the omega. He sniffs at the person who has walked into the room but its just a beta woman carrying some dried meat and fruit. She keeps her eyes firmly on the floor with a high blush on her face. She sets the tray down and walks out. Sokka stops growling and instead inspect the plate grabbing two pieces of jerky and eating one of them. He nudges at zuko until the omega opens his eyes “here eat. You need it.”
“How can you think about food?”
“Please eat?”
“Fine” zuko takes it and begins to eat
Sokka lays his head down on zukos shoulder covering the omega as best he could “hey zuko?”
Zuko yawns “yeah?”
“You were with katara and the aang when ba sing se was taken right?”
Zuko doesnt answer for a second but when he does he sounds guarded “maybe”
“Is aang dead? For real?”
Zuko sighs and looks to the door he lowers his voice and whispers in sokkas ear “keep your voice down they could be listening.”
Sokka lifts his head “But is he?”
“The avatar is alive. He has to be. Your sister had water that she said could heal a scar. I'm sure it could save the avatar as well.”
Sokka sighs heavily. “Thank you.”
“Dont thank me yet. Our lives are going to be hard from this point on. Ozai has a plan for us.”
“He knows theres going to be an invasion. Theres no doubt they're going to attack this place.”
“We can make a plan later, we should rest now. Its going to be a long few days. My heat isnt over yet.”
Sokka lays his head back down. “Were you forced into this too?”
“Yeah, yeah I was.”
“Do you want to come with me? When i escape? You could come with me and we could find the group. I bet youd be a great teacher to aang. He needs a firebender to teach him.”
“I would like that. But I think that they wouldn't accept me.”
“They would if i were with you. If i told them you helped me they would take you in. aang would take anyone in, hell he would take ozai in if he thought he changed.”
“He's much too trusting.”
“Yeah but thats what makes him, him. So like, do we have a partnership?”
“Yeah ill be your partner. We’ll get out of here.”
“Cool.” sokka’s knot is finally down enough for him to get out of zuko. As he leaves zuko lets out a loud groan as he shudders. Sokka finds himself blushing. “Im gonna cover us up ok. We should sleep some before it starts again.”
“Mmmm ok.” sokka lays down next to zuko and covers them with the blanket at the foot of the bed. “Can we still cuddle? Or would that be weird to do.”
Sokka thinks about it for a second before throwing an arm out so zuko can cuddle up to him. “I think we're over weird. I mean i just had my dick in you id like to cuddle. Come on over.”
Zuko slides over until hes laying his head on sokkas shoulder he throws an arm around sokkas stomach and is out in minutes. Sokka stays awake for a bit running his hand through zukos hair as the omega begins to purr again. He isnt sure what to make of all this, he's scared about what's about to happen. About what has already happened. Eventually sleep finds him and he falls into a deep dreamless sleep.
