Stealing a Thief's Heart

And Keeping It

Epilogue: Winning the Game

"...And then the beautiful princess fell in love with the dark king, but her parents wanted her to return home to their castle on the big mountain. So when the father wanted to take his daughter back, the dark king found a loop-hole and fed the beautiful princess three magical seeds that made it possible for her to defeat her parents' almighty orders so she could stay with him."

"And they lived happily ever after, papa?", asked the little red-haired girl wide-eyed.

The Italian man laying in the center of the bed smiled and ruffled her hair. She was closely cuddled next to him, sucking her thumb while eagerly listening. Tyson was laying on Nico's other side.

"Of course they did, my sweetheart", chuckled a voice from the doorway.

"Pops! You're home!", cheered the brunette boy. "Papa is telling us a story! Come, come!"

Jason shed his jacket and pulled his tie off before collapsing completely exhausted next to Tyson, ruffling the boy's hazelnut-colored hair. He leaned down to kiss his forehead, taking a look into the tattered book his boyfriend was reading from.

"As your papa said", continued Nico, turning his head to kiss Jason briefly. "They lived happily ever after in the big palace. And now it's time to sleep for you two."

"No. Not until big brother returns", disagreed Tyson stubbornly and yawned widely.

"He will return very late today, Ty", sighed the CEO tired. "And he told you so this morning when he drove you to school. And you need your sleep now."

Jason and Nico stayed silent for a couple of minutes, exchanging smirks while the children's yawns grew wider and wider until they were both deep asleep. The blonde had yawned too.

"He wouldn't always return that late if you wouldn't have bought that stupid old car for him", muttered the cop with a pout, shifting himself and Ty so he could rest his head on Nico's shoulder.

"What was I supposed to do?", grunted the Italian with a slight glare. "He was all wide, sea-green kitten-eyes begging for a treat when he saw it. How could I ever say no to that?"

"Okay, okay", sighed Jason, knowing those kitten-eyes very well. "Still, it's annoying. How am I supposed to lead a very important task force while listening to my partner's complains about how her husband spends all night at the garage helping my boyfriend. Who I miss too."

"Oh please, that's nothing", snorted Nico and rolled his eyes. "I have to listen to third-hand complains! My assistant Lou keeps complaining about how her girlfriend Miranda is complaining to her during their 'alone time' that Grover is being all grumpy at work at the 'Demeter's Garden' about his wife's complains of Will being all whiny at the hospital, as if being a nurse there wouldn't keep her busy enough. No, it's even worse than third-hand... It's just down-right ridiculous."

"That's our family for you", chuckled Jason amused, kissing Nico again. "But I'm really feeling bad for Juniper. Being a nurse at the hospital is hard enough as it is, but with this loon running around and shooting people, the guys at the Apollo's Heart are taking double shifts after double shifts."

"Yeah. How is the search going?", asked Nico with a worried frown.

"Oh, thanks to an anonymous tip signed with xoxo, we're pretty close", chuckled Jason.

"I don't like Percy taking care of psychopathic killers", growled the Italian.

"He doesn't do anything actively", reminded the blonde, caressing Nico's hair. "I think he's just using some connections, those brothers he refuses to introduce to us... And then he's telling us. He's just helping us and not endangering himself. You know he wouldn't do that."

"No, certainly not", snorted a voice from the door-way. "I hadn't been able to sit for a week the last time I did something you deemed reckless. Not going to do that again."

"You're back", noted Nico with a smile. "Finally. We've been waiting for you."

Percy yawned and stretched some, showing off his well-defined body. He was dressed in skinny jeans and a tight muscle-shirt, glistering with sweat and oil in the dim light of their night lights. Jason and Nico licked their lips in pure want, staring at him wide-eyed like two predators. The teen smiled apologetically and collapsed behind Ella, kissing the back of her head and shifting so he could bury his head in the Italian's neck, also kissing that and nibbling Nico's pulse.

"I'm sorry you two", murmured the teen and yawned. "For being away at the garage so often, for leaving you alone with the kids last weekend for a... eh, vacation with Grover and Rach. And I'm also very sorry for coming home so late, looking as hot as I do and then having the kids in our bed."

"Okay, first, I was the one who put the kids into our bed", chuckled the CEO. "And I for my part really love with how much enthusiasm you work on that car."

"And that vacation is not to be mentioned", grunted Jason, pretending not to know. "But the weekend with the kids was great, we visited Nico's parents. We all had fun."

"Oh, yeah", grinned Percy broadly. "Rach told me that Hazel said to her just how much your stepmother adores Ella and Tyson. I can't wait to meet her, by the way. I mean, it had been six weeks now that we're together. I want to finally meet your parents... if it's alright with you..."

"Uh... Well...", drawled Jason, leaning slowly over Nico to kiss Percy. "We kind of made plans for Nico's parents to come over next weekend. You think you'll find the time?"

"What?!", yelped Percy wide-eyed and as silent as possible to not wake the children. "Next week? I have to clean and get everything ready and arrange food! Oh goodness, I have to ask Silena for help with that! It needs to be really good! And I should go shopping, I can't wear-"

"Calm down, love", chuckled Nico, running his fingers through the soft, black hair. "My parents don't bite. And all of that still has time. How about you tell us about your lunch with Rachel?"

Percy blinked a few times and tried to calm himself, cuddling closer to his family. "Lunch was fine. She was being a bit cranky, but that's normal. It's Monday, she hates Mondays. Especially after a hei—vacation for the weekend. But other than that, she was pretty enthusiastic. Third week working at the museum and she still enjoys it. Probably the first time I saw her like that."

"I still think it's weird to let an art thief work at a museum", muttered Jason amused.

"You meant to say an art student with a Bachelor of Arts", corrected Percy and grinned.

A loud whining interrupted their conversation. "Come here, Mrs. O'Leary, or you'll wake the kids."

Jason beckoned the big, black dog onto their over-sized bed so she could curl together at the foot end of it. The blonde chuckled amused. It was what he had always wanted. The dream job, the big house, the love of his life, the wonderful children and the obedient dog.

He was back as leader of their task-force, though not responsible for the Black Siren anymore since that thief seemed to have vanished from the surface of the world. Jason suspected that they just kept it in the dark now, threatening the people they stole from with going public about the already stolen items thus leading to no one notifying the authorities. At any rate, he was grateful to not be forced to capture his lover. His lover, who now was very happy working at Hephaestus' Engines, though also getting them all addicted to repairing the car Nico had gotten him for his twentieth birthday.

As for their friends? Well, Juniper had gotten back into her original job as a nurse with a little help and guidance from Will at the Apollo's Heart Hospital.

Grover had gotten back to the Demeter's Garden, providing the di-Angelo-Grace-Jacksons with gorgeous flowers every week and had helped re-designing their garden.

And Rachel was Hazel's personal assistant at the Muse Museum, her knowledge of art and especially so the security measurements being pretty handy for the curator.

Luke and Ethan were behind bars for good. Jason was pretty sure they would try to escape at one point, but for now they were far away from their Percy. The blonde smiled, grasping Percy's hand.

"Are you alright, Percy?", whispered the cop, the question meaning so much more.

"I love you", murmured Percy in reply, slowly closing his eyes. "How did tonight's fairy tale end?"

"And they lived happily ever after", chuckled the Italian, kissing his head. "Sleep well, my loves."

~*~ The End ~*~

Author's note: Yes, the real, proper ending. It's OVER. Damn, that makes me sad... But this had been supposed to be a oneshot anyway and now it's such an ass-long story. And now it's over...
Before I start crying here, I got some good news. I've had that poll up, you know with which multiple-chapter story you guys would want to read, and one of the winners was also a Jason/Nico/Percy one - so expect to find a new threesome story with our little Big Three under your Christmas tree this year. ;) Just watch out in the loads of updates I do this month (no kidding, I feel like I'm doing nothing else aside from writing this month! _ ) for a story called "The Most Sparkling Diamond". And thank you all for taking the time to read this story and even more so for reviewing. Especially the reviews. They make my day.
