Zuko knew he was gay. From the age of 13 onwards. From the way he would look at the older men in his fathers guild to the disapproving sounds his father made when he caught him told him so.

So it was to his utter surprise when he found himself crushing on his boyfriend's girlfriend. 

….

Zuko and Sokka had been going out for at least a year when he brought up the idea of an open relationship. 

"I mean… I still love you obviously but I would like to bring a third person in. I love you but I know you have hard nos that are my yes's and it's just… I'd like to fill up those gaps?"  Sokka said, scratching his neck in embarrassment.  

Zuko looked at him, his eyes wide until understanding took over him. He knew he deprived him of some stuff, specifically sex. Zuko hated anyone touching him sexuality,  Sokka included. But he knew Sokka was an incredibly touchy person and touch was his love language. He knew he was depriving him of it and he sighed gently. He wanted Sokka to feel loved and if he had to put up with some random person being added he didn't see  why he had to disagree. 

"Alright," he said finally.

Sokka's eyes lit up and Zuko knew he had made the right choice.

….

Meeting Suki for the first time was nerve wracking.  A powerful woman in her own right. She had a smile anyone could fall for and Zuko  understood why Sokka was so smitten with her. 

He couldn't bring himself to hate her, not when she gave him massages when she saw he was tense or fed him delicious meals when it was just them at home.  He tried, god he tried to hate her but he couldn't.

…..

It was a day when just Suki and Zuko were home alone, Sokka away on a business meeting.

"You know…" Zuko began. "I thought I would be jealous, watching you kiss Sokka or having to share our bed with you…but… I see how happy you make him," he said nibbling his lip. "I fear I'm not what he wants anymore."

Suki's green eyes widened in surprise and then softened. She nudged Zuko's shoulder and then smiled. "He talks about you alot you know. He loves that you let him ramble. Or when you two paint together you never tell him his paintings are bad-"

"Because they're not,"  Zuko interrupted, his face flushed.

Suki laughed. "You're so smitten for him and so is he for you. Don't you dare think otherwise."

Zuko smiled and looked away. "Yes. ma'am."

…

"We should kiss,"  Suki says one day to Zuko.

He's painting and his brush slips and he yells as the water he used to clean his brush spills onto his painting, creating a blob.

"Shit,"  Suki said, reaching over to help.

Zuko's head snaps up. He didn't realise how close they were when he locked eyes with her. 

His breathing was heavy. What did she mean by kiss? He was gay why would she -oh.

He didn't even notice when he leaned in to kiss her, his fingers reaching for the back of her neck to pull her closer.

She hummed in satisfaction as she reached to untie Zuko's bun, letting his long hair cascade down his shoulders. Oh how she loved it long.

They kissed for a moment longer before Zuko parted, his eyes wide.

"I…I.."

She smiled gently. "Might not be as gay as you thought you were?"

His eyes traveled to her lips and then to her eyes. "What do I do?" He asked, sounding lost.

Suki reached for his cheek and cupped it gently. "You allow it to happen. I think Sokka would actually be into it ," she said with a wink. 

She leaned to kiss him again when said boyfriend walked into the room. Zuko tried to pull away but Suki was strong. 

"Oh. I was wondering when you'd finally let it out,"  Sokka laughed. 

Zuko finally managed to let go of Suki. His lips were swollen and his cheeks were flushed. 

Sokka laughed again. "You look perfectly debauched, Zuko."

Zuko flushed deeply and looked away. 

"Does that mean we're like…. All boyfriends and girlfriends?"  Sokka asked.

"I dunno, that's for Zuko to decide," she said, looking at the shy man in front of her.

She saw him breathe in before speaking. "If I say yes will both of you leave so I can clean up my painting?"

Sokka whooped and rushed forward to kiss Zuko and then Suki.
