Welcome to my new story! Don't worry, I'm still working on More Than He Seems. This is just a little side project I wanted to work on. There is some slight dub-con because of the nature of ABO fics. Nothing too bad. I hope you enjoy!

Being an Omega in an Alpha dominated world was rough. Being a male Omega was even rougher. Female Alphas were cherished and encouraged. Female Omegas and Betas were considered normal. Male Omegas were often abused in their society. They were rare and considered abnormal and an abomination. That's why Tony Stark HATED being an Omega. When he presented at the age of 11, his father had locked him up tight in his room and beat the shit out of him. Tony had been on illegal scent blockers and heat suppressants ever since.

Tony spent his life thinking about all that he would miss out on. Because of the scent blockers, Alphas thought he was a Beta, so they would never try to court him into a mating heat. He would probably never have children. Sure, when Tony was young and dumb he sure didn't want kids, but now that he was older and more mature he liked the idea of a little mini him running around. Honestly, at one point his baby fever was so bad he almost went off his scent blockers. If he had done this he would have lost all his rights to the company and his suits. Omegas didn't have many rights. Sure, if he had a mate and his mate said it was ok he could keep everything. Unfortunately, Tony Stark was lonely as shit and didn't have a mate.

So, no mate, no kids, and half the Avengers didn't trust him. Bruce and Thor were the exceptions. Bruce was his science bro and a "fellow Beta". Naturally, they found friendship. Thor was an Alpha and royalty. He literally had no business even talking to Tony, but he did. It was actually Thor who had convinced the other Avengers to let Tony into the pack.

So yeah, Tony liked Thor. Maybe a little too much. So that's why Tony was so surprised when Thor would bring him little trinkets and such back from Asgard. Little things for Tony to take apart and learn from. Tony didn't understand. He made sure that Tony always had food and that he didn't get cold. It felt so much like courting. But Thor thought Tony was a Beta, so it couldn't be that. If Tony was braver he would have confronted Thor about it, but he wasn't. It made him feel loved and cherished. Tony had never felt like this in his life. He spent his youth being abused and his young adult years being manipulated. He had never really felt love. So yeah, Tony wasn't giving this up anytime soon.

That's when the problems started.

Well, the rest of the team saw it as a problem. Tony and Thor saw it as a blessing.

You see, in order to trigger a bonding heat, the Omega needs to completely trust their partner. Once this happens, the Omega shuts down and becomes completely dependent on the Alpha of their choosing. They often find loud noises to be upsetting and different sensations such as touch, and smell can become overwhelming. 3-4 hours later the Omega's heat is triggered as well as the Alpha's rut. 99% of the time bonding heats end in pregnancy.

Tony never thought he'd get to experience this. Which was why he was so surprised when one evening he was doing some paperwork in the living room when everything just suddenly became too much. Every sound, every texture around him, every scent was just too much. Tony didn't really know what was going on with his body, so he opted to just go with his instincts.

The team was just as surprised as Tony was when the found him curled up in a ball with his hands covering his ears on the floor of the living room.

"Stark! What are you doing? What's wrong?" shouted Steve as he walked closer.

Tony just pressed on his ears harder and shook his head. His eyes were screwed shut. When Steve went to shake his shoulder Tony completely freaked out and was whimpering. Steve took a step back to let someone else try. They let Clint try next. Same result. Well, maybe he needed a woman's touch, so they sent in Natasha. Same result. Maybe this was a Beta thing. They sent in Bruce. Same damn result. They were all at their wit's end and JARVIS was being silent. The only other thing they could think of doing was calling Thor. They managed to get JARVIS to call Thor up from the gym. When he got up their Thor knew exactly what was going on and he knew what to do. He walked up to Tony slowly and knelt down beside him.

"Anthony. It's Thor." He spoke softly. Tony looked up and met Thor's eyes. What he whispered next shocked them both.

"Alpha?"

Thor was stunned. Had he finally found his mate? Thor just gathered Tony into his arms and held him close placing one of his own hands over Tony's ear to block out the extra noise. Tony was feeling a bit mortified. Now everybody in the room knew he was an Omega and that he had somehow bonded with Thor. The other occupants in the of the room were in varying degrees of shock and anger.

"Thor! Care to explain?" seethed Steve.

"I'm just… I'm so happy right now. I never thought that I would ever succeed in courting an Omega. No Omega has ever trusted me enough before. I've been courting Anthony for months now. He's just so smart and kind. I couldn't help myself." Whispered Thor as he held Tony closer and rocked him back and forth.

"Nobody here even knew he was an Omega. How did you know? Did he tell you? How did he get away with hiding this his whole life?" asked Bruce.

"I wasn't aware that he was hiding it. I can smell his scent clearly. I don't know why you all thought he was a Beta." Said, Thor, as he nuzzled Tony's hair.

"Thor, you could have any Omega you want. You don't want that one." Said Natasha plainly. The comment made Thor growl.

All the angry Alpha pheromones in the room were making Tony uneasy. It was just all too much. Tony whimpered and tried to make himself smaller in Thor's hold. Tony had never given in to his instincts in his life. He didn't want to be seen as weak in front of others, especially in front of an Alpha like Captain America. He could just feel his life falling apart as he sat there in Thor's arms. At least there was a chance that Thor would be nice to him. They would need to talk once this was all over.

"If you are all done making fun of my mate then I think we'll take out leave." Growled Thor as he scooped Tony up and walked out of the room.

"Hush now little one. I will not let them hurt you." Said, Thor, as he nuzzled against Tony's neck.

Thor brought them up to Tony's room because he thought it would be the most familiar place for Tony to make his nest. Once Thor gently placed Tony on the bed he made sure to remove their shoes and socks before cuddling up to Tony on the nice soft bed.

"Rest now little one. Your heat will begin soon, and you'll need your strength." Thor pulled Tony close to his chest and scented his neck. Tony had never felt so warm and safe in his life. He was so comforted that for once he listened to his body and drifted off to sleep.
