Work Text:
Ever since he was little, there were two things Ace had always thought he would never get: love and a family.
He had been left in an orphanage when he was still in diapers and his parents had never shown up, leaving him to himself.
Dadan, the orphanage caretaker, had always been the only parental figure he ever knew, and it's not like she was a great example of the perfect parent, but she cared for him in her own way, so Ace made that enough.
Then when he was ten years old, he met Luffy and Sabo.
Luffy had been left to Dadan by a grandfather who was too busy to care for him, while Sabo had been taken in by passersby who had found him on the street after he ran away from his abusive biological family.
From the moment they met, they became inseparable.
A month later, they took an oath and they became brothers.
They promised that they would be adopted by the same family and would be brothers forever.
It wasn't until a year later that their dream came true, when the Red showed up at the orphanage, declaring that he wanted to adopt all three with his typical enthusiasm.
The three children said goodbye to a tearful Dadan and then left with their new dad.
They were finally a real family.
That said, Ace thought he got more than he deserved.
So love was the least of his thoughts.
Then the Red turned his life upside down once again.
When Ace was twenty, Shanks decided to introduce his boyfriend and his family to them.
And it was at that point that his beautiful green-haired angel entered his life.
Zoro was the best thing that ever happened to him.
When they started dating, Ace found it was absurd that Zoro's siblings were so bloody protective of him.
Ace had never been jealous of his brothers, he wasn't a jealous brother and never would be.
That was what he thought.
Then his innocent little brother one day showed up arm in arm with a boy who was clearly older than him, who looked like an organ dealer, full of tattoos and dressed as an emo and introducing him to them as his boyfriend.
Boyfriend.
Trafalgar Law, that was the boy's name.
Ace didn't like him at all, he hated him.
And that's how he was here, lurking in his car following his little brother on his date with the organ dealer.
"Ace, this is ridiculous" said his boyfriend sitting on the passenger side with his arms crossed over his chest "When you asked me out, I thought you meant a nice romantic date, don't tail Luffy and Tora-o"
"And I don't know what the two of us have to do with it" said his brother sitting on the back seats, next to his girlfriend.
"Don't call him with that cute nickname" he hissed at his boyfriend "I just want to make sure he doesn't kill Luffy and sell his organs on the black market"
"He's studying to be a doctor, Ace" Zoro sighed "he's literally doing the opposite of what you said"
Sabo rolled his eyes.
"You're too paranoid, Ace" he said "I'm a bit jealous too, he's my little brother, but Law seems like a cool guy to me"
"I'm not jealous" he gave him a dirty look "Something's wrong with that guy, I don't like him"
"You're definitely jealous," Zoro said with a smirk.
"Ace-kun, Luffy is grown up by now, it's also normal that he wants to explore his sexuality" Koala said softly.
"Sexuality? Are you talking about sex? Do you think Luffy and that organ dealer had sex?" he asked, his eyes widening "I knew he wasn't to be trusted, that criminal deflowered my little brother"
"Oh my god" Zoro sighed, running a hand over his face "You're getting ridiculous"
"Yeah...what do you expect them to do when they're alone? Look at each other's faces?" asked the only girl in the group.
"Wait...it doesn't mean they must have had sex, right?" Sabo asked, making a horrified face.
"Sabo-kun, are you starting now too?" his girlfriend chided him.
"Can we forget all this bullshit and go on a real date instead of stalking Luffy's? I'm bored here" the greenette asked crossing his arms over his chest annoyed.
"I agree" Koala said with a sigh.
"But..."
"Ace!" Luffy's enthusiastic voice cut through his protests.
He stiffened as he glanced at his smiling little brother.
"What are you doing here?" he asked enthusiastically "How nice to see you!"
“We…were on a date,” he said pointing at his boyfriend.
"Hi, Luffy" he said quietly, then nodded to his brother's boyfriend "Tora-o"
"Zoro-ya" he nodded.
"There are also Sabo and Koala," said the boy in the straw hat, looking inside the car.
"It was…a double date," the blond said.
Luffy looked at them curious for a few seconds, then gave them a huge smile.
Oh no, Ace knew what that smile meant, and he didn't like him at all.
"Tora-o and I will join too"

"The stakeout was a bust" Ace sighed dramatically as he parked the car outside his boyfriend's house.
"Can you just admit that Tora-o is a good person and that you were just playing the jealous brother?" asked the greenette crossing his arms on his chest.
"Okay, I was fucking jealous!" he exclaimed "That stupid dude looks perfect, but I still don't like him, he's full of tattoos"
Zoro raised an eyebrow.
"You have tattoos too, Ace" he said "Don't be hypocritical"
The freckled boy crossed his arms over his chest and snorted.
“You're my boyfriend, stop defending another man” he said, frowning at him.
Zoro smiled.
"What? Now you're jealous of me too?" he asked bringing his face close to his neck "You know I only have eyes for you"
Ace smiled satisfied.
"Tonight my father and siblings are not at home" he whispered against his ear.
He shivered.
"You will be my downfall" he whispered.
Be that as it may, he didn't have to repeat it twice and dragged Zoro into the bedroom.
It wasn't until after he was done having the best sex of his life with his beautiful boyfriend that he realized one thing.
If he was at Zoro's house, Sabo was at Koala's house and Shanks was not at home then...his house was also free.
Luffy wasn't going to bring that Trafalgar guy into the house to do…those things, was he?
Ace and Zoro took advantage of any moment to have fun under the covers, but that didn't mean Luffy would too, he was still little and innocent and he couldn't...
"What are you thinking about?" his boyfriend asked sleepily, interrupting his thoughts "I can feel the wheels in your head turning"
"I have a free house too, Luffy didn't bring that organ dealer to do sinful things, did he?" he asked in a panic.
Zoro sighed, resting his head on his chest.
"You're just hopeless"
