Chapter 15 – Payback

When Lucifer arrived home – how strange, but so very, very good, it was to think of it as home – he hadn't expected to find his brother and his Harry cuddling together on the couch.

If he didn't know that neither would ever betray him like that he would have been jealous.

As it was, he only smiled at how cute his beautiful, little wizard looked.

"Lucifer." He looked at Gabriel, happy to see the protective gleam in his brother's eyes. He had seen that the two were becoming closer, but it was a nice surprise to see that Gabriel accepted Harry so readily. "What was happening? Is everything alright with Harry?" Gabriel's wings fluttered slight, closing even more around the mortal in his arms.

Lucifer took a seat on the other side of Harry, his wings wrapping around his brother and Harry.

"Everything is fine," he said. "I just felt Harry's fear when he was facing the dementors when he was younger."

"You could feel him so far back?" Lucifer could understand his brother's surprise, for him to be able to feel Harry so far back meant that Harry already felt rather strongly for him at that time. It was surprising, especially because at that time he had been locked away with no way of communicating with his wizard. "He truly is something else, isn't he?" Gabriel was smiling at the sleeping wizard, and Lucifer grinned, completely agreeing with his brother.

"Brother, I was wondering… how do you feel about going hunting?" Lucifer's smile was nothing short of malicious.

"What would we be hunting and why?"

"They hurt Harry."

When Gabriel's eyes darken and his Grace turned almost frosty, Lucifer just smiled – it looked like he was going hunting with his brother.

Harry knew that something was up with his two Angels. They were acting shifty. It had started the previous day when he had woken up cocooned between the two of them, feeling safe and protected.

"Uncle Gabby." Harry's lips twitched at the name his son had thought up for Gabriel, especially when he saw Gabriel twitching at the atrocious name. "Wanna play outside, Uncle Gabby. Play with me?"

Harry hid his grin behind his tea cup when Teddy morphed into a tiny version of Lucifer with Harry's green eyes. Harry could see Gabriel folding like a house of cards.

"Sure, munchkin." Gabriel grinned. "What do you want to play?"

Teddy cheered, grabbing Gabriel's hand and pulling him outside, babbling all the while about magical castles and brave knights.

Harry shook his head, that boy had Gabriel wrapped around his little finger. He frowned slightly when he looked back up and saw Lucifer staring at their retreating backs.

"What is it?" he asked and took a seat on Lucifer's lap, smiling when Lucifer's arms wrapped around him.

Lucifer nuzzled his neck and sighed, his warm breath making Harry shiver.

"I love seeing Teddy like that. I love it when he looks like a mix of both of us. It makes me feel like he's ours. I want him to be ours." Lucifer took a shuddering breath. "It's forbidden for a mortal and an angel to have a child together, Harry. Even so, I want it so much. I would gladly break all of our Father's laws for it."

"Lucifer..." Harry didn't know what to say. He had never thought about it – hell, he had Lucifer never even had sex – but now that Lucifer had spoken those words… it woke something in him; a fierce longing, one he had never thought he had. He loved Teddy with everything he was, but to have a child with Lucifer?

He crashed his lips against the Angel's, Lucifer responding with equal passion as soon as their lips met. Harry moaned and let Lucifer take control of the kiss, happily surrendering to his Angel. Lucifer wasted no time in mapping out his mouth, and hands gripped his waist in a bruising grip. He moaned when Lucifer latched onto his neck, gentle nips trailing a hot path towards his collarbone.

"Harry," Lucifer growled and the sound went straight to his cock.

"Oh, God!" Harry moaned, only to yelp right after when Lucifer bit down on his neck with enough force to leave a mark. The sting was quickly soothed with soft strokes of Lucifer's tongue, and gentle kisses.

"Don't say another's name while you're with me, especially not our Father's," Lucifer muttered against his neck, and Harry chuckled.

"Hadn't thought about that," Harry replied, tilting his neck slightly to give Lucifer easier access. "It would kill the mood rather quickly."

Lucifer snorted, stopping his ministrations and just nuzzling his neck.

"Yes, it truly would. It's bad enough to know that he could see us of he were so inclined." Lucifer laughed at Harry's horrified look, only to stop abruptly at Harry's firm declaration.

"We're never having sex!"

When Harry called them back to have lunch, Gabriel noticed the kicked puppy look his brother had immediately. He also noticed how determined Harry was not to look at his brother.

Slightly concerned, he probed his brother's mind, trying to see what the problem was, only to burst out laughing. He was laughing so hard that he bad tears running down his cheeks and not even the death glare that Lucifer was throwing him was enough to make him stop.

Who would have thought, Lucifer, the Devil himself, being reduced to such a state by a tiny mortal.

"Ah, dear brother, hopefully you'll be able to convince your feisty lover that dear, old that isn't into voyeurism." He patted his brother's back comfortingly, doing his best not to break down laughing once more.

Who would have thought, blue balls was something even the Devil feared.

"What's up with you and Gabriel?" Harry asked later that day when they were in bed, and Lucifer was wrapped around him.

"It's nothing, love." Lucifer's arms tightened around him. "Gabriel and I were just discussing a hunting."

"Hunting?" Harry frowned.

"Those dementors… they dared hurt you. I can't, I won't, let them get away with it. You are mine, Harry. Mine to hold, mine to protect, mine to love." Lucifer kissed the top of his head. "They will pay for harming you."

Harry took a shuddering breath and snuggled deeper into the warm embrace. For a moment he felt guilty for not even trying to stop Lucifer from doing whatever it was he would do. However it was a fleeting thought that was quickly overwhelmed by the feelings of safety that were filling his whole being.

He didn't have too be the hero anymore. He could just lean back, and enjoy the protection Lucifer was so willing to provide.

And if a few dementors had to suffer… well, it was about time they paid for want they had done to Sirius.
