A/N: Prompt: OUAT dad's club. Hope you enjoy it! :D

Killian was what this world called a "stay at home dad." Ever since Liam was born he couldn't bring himself to leave his child's side. When Emma was pregnant, everyone kept reminding him that being a father was going to be the most precious job out there. He would agree to that now one hundred percent.

His baby boy, who was now only two (time truly flies), had his mother's emerald green eyes as well as his own dark hair. He was the perfect mix of himself and Emma. He remembers saying those exact words through his muffled sobs when Liam was born.

Now as he has grown older, Killian realizes that the phrase "terrible twos" was not actually a myth. Liam finds a way to reach every delicate glass or vase that Mary Margaret gave to them as a gift. That's why he can't take his eyes off him for a second, or Emma would come home to their house in complete destruction.

Putting all that aside, he enjoys taking him to Granny's for lunch, the local park (though Henry mostly plays with him there), and to visit Emma at the station.

It was like any other day when he was suggested to join this.

They had just come back from the park, Liam's little toddler feet followed him into the station. It was an extremely humid day and finally being inside to the magical feeling of air-conditioning felt amazing. He embraced Emma, pulling her out of her chair so he could properly wrap his arms around her waist.

"How are my two handsome boys doing today?" Emma asked, as she moved in to kiss her husband and hug her son.

"Fine love, Liam and I just came back from the park. Henry was there too, I dropped him off at Regina's before we came here." Killian explained, "But Liam did put a handful of sand in his mouth again. I don't know what to do with our little scoundrel anymore. He's just stubborn like his mother."

Emma playfully shoved him, rolling her eyes at him accusing her of being stubborn.

"Well Liam certainly takes no orders from anyone, just like a pirate wouldn't. I wonder where he gets that." She teased back.

"I would say it comes from his own unique spirit." Killian crouched down, moving fast to pick Liam up and spin him around, causing his lad to laugh uncontrollably.

Emma laughed along, reaching out towards her son so she could hold him as well. Liam instantly let her lift him. He patted his mother's cheeks as she made silly faces at him, but Emma was forced to move from her spot once Liam began reaching out behind her to play with the files that were sitting in the half open drawers.

"Okay I think it's time we put you back down," Emma said, placing a lingering kiss on her son's forehead, "It's probably time for me to go back to work, and you two to go back to your play date."

Killian put on a gloomy face, clearly not happy they had to leave Emma again.

"Well I guess we should be on our way then, isn't that right my boy?" He asked Liam, taking his son's small hand in his so he could guide him out of the office.

"And where are my boys off to?" Emma asked.

"Probably back home. Nowhere else we need to be. We'll be waiting for you." Killian said, giving her one of his mischievous smiles, tempting her to kiss it right off.

Emma raised her eyebrows, giving both of them her own mischievous smiles.

"Are you mocking me Swan, or do I sense a new adventures idea?" Killian asked, wiggling his eyebrows.

"Oh you're both going to love this." Emma said, her expression clearly amused, "I know exactly what you two could be doing during the day while I'm gone."

"Which is…?"

"Dad's club, you and Liam could join Storybrooke's Dad's club."

"Come again? What the bloody he- I mean…" Killian was utterly confused, but quickly stopped himself from swearing in front of his son, especially since Emma gave him such a venomous look from almost doing so, "Love, what exactly do you mean by "Dad's club?"

"Dad's club. It's where all the dads hang out, take their kids there to play, and possibly exchange a few helpful parental tips. I know for sure my dad takes Neal, and Robin even takes Roland. It would be great for Liam to have friends to play with, and you could bond with the dads." Emma explained.

Killian couldn't help how his smirk quickly turned into a frown. It would be great for Liam to hang out with his friends, but he and the dads together was probably not a good idea, not that he wouldn't want to hang out with Robin and David.

"Lass I-"

"Come on, it will be fun." Emma said, standing there with her arms folded, Liam was staring back and forth between his parents before he decided to mimic his mom and fold his arms as well. "It's only twice a week. You could even just go once a week if you really wanted."

Two pairs of identical green eyes stared at him. When Liam gave him a pleading expression, he knew he was done for. He couldn't say no to the two loves of his life.

"Alright fine, I guess me and the lad could try this dad's club for a day or two," Killian said willingly, feeling his heart melt when Liam started jumping up and down with the widest smile on his face, "Where do they meet?"

"Well I know for sure they are meeting at Granny's this Tuesday, you could start then. I already signed you up."

"You're quite sneaky love, how did you know I would agree?"

"Well I knew you couldn't say no to me, and Liam seemed really excited about it when I asked him."

"Oh I see, you two had a secret meeting without me." Killian said, giving his wife a teasing wink.

He leaned in to give Emma a goodbye kiss before taking Liam's hand in his again and walking back out in the humid air towards their house.

When Tuesday rolled around, Liam couldn't contain his joy any longer. He knew it was Dad's Club day and made sure to wake up extra early to prepare, dragging Killian out of bed in the process.

When they walked into Granny's, they found David and Robin sitting in one of the booths. Neal and Roland seemed were pretty entertained with the dart board. This was going to be interesting.

Liam immediately let go of his father's hand and ran to play with his friends. That left Killian awkwardly standing in the door way, with Liam's bag hanging on his shoulder.

David noticed him first, nodding in his direction so Robin could notice too.

"Killian, so nice for you to finally join us." David said, getting out of the booth to join him at the door.

"Emma proposed this idea the other day, thought we needed something to do during the day while she was at work." Killian explained.

"Yes, she personally signed you two up; to be honest we had been waiting for you to join us for a while." Robin said.

"Well what exactly do we do in Dad's club?" Killian asked.

"Actually today we were going to go to the pond and have a picnic." David clarified.

"I didn't bring-"

"Its fine," Robin said, "that's why we're at Granny's."

A few hours later, and Dad's club were all sitting on a pink blanket that David shyly explained was the only clean one he could find at home. Neal and Roland took a couple of biscuits to feed the ducks, as Liam stood beside them, staring at them in awe. He seemed to be having a fun time, and Killian couldn't be happier for his boy.

"So Killian, what have you and Liam been up to before you joined us?" Robin asked. They both clearly seemed interested to know.

"I took him to the park a lot actually, but since he began eating the sand, I try to stay clear of the area."

They stared at him, giving him knowing looks.

"Neal used to do that, I assure you it was just a phase. He has grown out of it now, Liam will too." Killian was surprised to hear this; David's words gave him immediate comfort.

"I just worry for my boy; I wouldn't want him to get sick on my account." Killian said, glancing towards Liam. He would never forgive himself if something happened.

"It's a part of being a father, worrying is what we do best." David said.

Their conversation quickly turned into more of their young lad's mischievous shenanigans. When Killian brought up how Liam liked to touch every delicate thing in the house, the other men agreed right away.

"Don't even get me started, Roland has a tendency to touch everything at home, and Regina has so many fragile objects."

"I take it this is not a phase they will grow out of?" Killian asked. He felt amused at how similar their situations were.

"You just have to be patient." David reassured him.

They all were really bonding and Killian actually felt like he belonged there. This was why he was reluctant to join at first; he didn't believe he could fit in in just a day.

Later, after a long day of Dad's club, Killian and Liam finally made it home.

Killian had not realized the time; they were out later than expected. Liam was extremely tired from his play date, so Killian had to carry him home. His adorable little face was buried in the crook of his neck, and Killian thought of how precious this moment was.

When he opened the door he found Emma sitting by the television, clearly waiting up for them.

"Hello love." Killian greeted in a whisper.

"Hey, how was Dad's club?" Emma asked, as she made her way over towards them, embracing her tired boys in a hug.

"Brilliant. We are definitely going back."

And they did.

Eventually twice a week turned into five days, they had all agreed that they rather let the boys play together the whole week, and they spent the days sharing helpful tips on how to be a great parent. This mostly started arguments on who was the better father. Nevertheless, Killian enjoyed making new friends when new fathers joined and he made sure they all felt welcomed.
