So this is a kinda AU EMH thing I've always pictured.. It's kinda a mash up between Evo storm(favourite incarnation) with Panther. Where they got married young (she was 17he was 21) and already have two kids, Azari age 3 and N'Dare age 18 mo I really live this universe I've created for them so you might be seeing more sometime. Still unedited. Going to post it in EMH as well.

"Baba, I'm thirsty!" Whined the small boy tugging on his fathers sleeve. Turning to look at his three year old T'Challa bent down to pick the young boy up.
"Have you asked Mr. Stark for something to drink?" He asked Azari tilting the boys chin up to see him better. After the boy shook his head T'Challa turned to their host and inclined his head slightly.
"Would you mind, Tony, some milk or fruit juice?"

Tony laughed and nodded "You know Azari, you can ask me instead of your dad sometimes. I don't bite!" Signalling to one of the servers he turned to the little boy and smiled.

Azari buried his head into his fathers head before smiling shyly at Tony.

With a sudden thump to his back, T'Challa stumbled slightly, before looking up to see the god of thunder laughing merrily with a cup of ale in his hand. "Thy young one is so amusing with their habits! Where hath thy daughter gone to?"

T'Challa glanced around the crowded room as his wife carrying their 18 month daughter in her arms, coming up and pecking him on the cheek the baby girl settled into her mother. "She's falling asleep in my arms."
Ororo smiled at her husband before smiling at each of the three other men in greeting.

"Azari seems quite tried as well." T'Challa adjusted his grip on his son. "Should we call it a night then?" He added ignoring the gasps and groans from Tony, Thor and Clint.

"I'm not tired baba." Azari said with a yawn, hugging T'Challa's neck close to him.
"Listen to your kid, T'Challa, it's barley even ten!" Hawkeye said with a glance at the clock. "The party's barley started!"

"If you really need to dump the kids I've got a few guest rooms they can sleep in." Tony sipped his drink as the server brought a small glass of milk for Azari "That's what the Richards are doing with their kids, Franklin bopped out a few hours ago, Valeria's looking like she's going to go out too."
"Aye, there's much festive things you would be missing!" Thor nodded in his booming voice, causing N'Dare to screw up her face and curl into her mother with a whimper.

Taking the milk from the waitress, and starting to hold it for Azari to sip, T'Challa glanced at his wife, who turned to Stark and chuckled. "It depends, is the rest of this party going to be a child friendly one, or is it going to be like the others you've held?"
Shrugging and downing the rest of his drink he replied "What can I say, what happens happens!"

Chuckling along, Ororo shook her head. "I don't think so Tony, thank you for the wonderful party. Happy New Year to you all." Giving each man a kiss on the cheek, Ororo turned to her husband "I'm just going to say goodbye to a few more people, then I'll meet you in the car."
"God, you're whipped T'Challa" Hawkeye said with a shake of his head. "And you've only been married 7 years, it just goes downhill from there."

Watching her walk away, T'Challa put down the glass of milk on a table. "Thank you for inviting us, Tony. I wish you all the best for the coming years." Giving the men each a firm handshake, and nearly avoiding a bonecrushing hug from Thor, T'Challa made his way out of Tony's penthouse and to the car, where he spent another thirty minutes waiting for Ororo. Surely, after they returned to the Embassy and put the children to bed, he and Ororo would have their own New Years party.
