Regulus

So focusing on being the best step-dad for Harry was challenging. James' grief spells about Lily were challenging but valid. Of course James was going to feel these waves of grief. It wasn't even that long ago it had happened. Being on holiday was a nice distraction from the Horcruxes. Remus and Sirius had got engaged, so that was wonderful. Remus also was having spells of grief about Lily, they had been particularly close. He was sure Sirius would be experiencing them too however Sirius seemed to be hiding it to help his now fiance.

Harry was challenging, he screamed when they walked around for too long. He pulled Regulus' hair a lot and mostly Regulus didn't feel paternal towards him no matter how he tried, oh and he tried. He felt more of a connection to Luna and Draco. Which he felt awful about, Harry was literally his husband's son. Harry was also a reminder about how he fucked up with James. Harry wouldn't be born if Regulus hadn't taken the dark mark. Well no James didn't leave as soon as he discovered it. James tried to help Regulus, James left because of Regulus' actions after getting the mark.

James would say it all worked out (mostly) because he got Harry his only wishes were that Regulus didn't have to suffer in the ranks of the death eaters and also of course that Atlantis had been born unharmed. James could never regret Harry; he didn't regret his time with Lily either but he had made it clear he hadn't loved her, not in the way he loved Regulus. He was also making Regulus aware that no one loved anyone the way he loved Regulus; it just wasn;t something that was possible. Regulus reckoned if James could feel how much Regulus loved him he would understand that it is possible because Regulus was quite sure there was never a love like Regulus Black (now Potter) has for James Potter.

So really Regulus would like nothing more than to make it a happy family with Harry, he didn't know what was wrong with him. Why couldn't be the step-dad Harry deserved. James had been singing Regulus' praises since they got to DisneyWorld all really for what Regulus would call the bare minimum of what he was doing with/for Harry. Regulus also thought if he had to look at another person in costume he was going to lose it. Regulus had many late night walks with Narcissa and Pandora. They would both try to offer up advice about the Harry situation but none of them knew what it was like for the love of their lives to have a child with someone else.

The whole lot of them usually has breakfast and lunch together then James would steal Regulus and Harry away to dinner alone just the three of them. It was nice as it could be. Regulus wanted to feel like a family he did, he really did. He didn't know what was stopping him. He loved James so he should by extension love Harry, Harry was a part of James. He was the spitting image of James apart from the eyes you would have thought James just spat Harry out. So what was Regulus' problem, Regulus hated that he was like this, Regulus indulged in self loathing quite a bit though.

What brought Regulus joy was how happy Sirius was to be engaged. He didn't have an actual ring; he had a paper ring that Remus had charmed once they got out of view of muggles back in their hotel room so that it wouldn't rip or break. Regulus thought that was really sweet. If anyone deserved happiness it was Sirius and Remus, for Merlin's sake they spent their entire school years in love with each other only getting together the summer

before their last year after Sirius went to Remus' in a meltdown after finding out Regulus was pregnant.

Regulus was overjoyed Sirius had taken it well this time. He was truly happy for Regulus and James and every time they went into a store in the park he bought either a pair of baby socks or a pair of baby shoes. This warmed Regulus' heart, he was going to be such a good uncle. His baby was so lucky that she was going to have uncles like Sirius and Remus. She really was going to grow up around love. James had grown up around love and it made him be able to love so deeply and purely, Regulus and Sirius' upbringing was different. Regulus was a bit standoffish with people at first though he found once he formed a connection he could love hard.

After another day strolling around the park they called it a night. Sirius, Remus and Narcissa headed to the bar, everyone else headed to their rooms (Draco with Andromeda) James and Regulus cuddled up together and James ran his fingers through Regulus' curls,

"How did I get so lucky?" James whispered,

"The lucky one is me, darling," Regulus said, turning his face to James and batting his eyelashes.

"Pretty sure you were blessed by Aphrodite," James croaked,

"What?" Regulus chuckled,

"You are so fucking beautiful love," James shook his head, "I think she chose you, and blessed you, gave you a gift, its not normal how beautiful you are," James kissed the side of Regulus' forehead.

"James you talk a lot of nonsense, you know that," Regulus grabbed his hand and intertwined their fingers. James kissed Regulus' hair.

"You've told me before baby," James chuckled,

"I love you," Regulus breathed and even after all this time James' breathing hitched,

"Well now that just proves that, I in fact am the lucky one. I love you too sweetheart," James was practically beaming, so was Regulus, he wanted to stay in his husbands arms forever. Cuddled up like this precious undisturbed moments,

"Who do you think Sirius will ask to be his best man?" Regulus wondered.

"I'm sure it'll either be both of us or I'll do best man for Remus and you'll do best man for Sirius," James shrugged.

"Remember all the prewedding jitters, remember the lead up, remember the excitement," Regulus recalled fondly,

"Yeah I was pretty chill you were kind of stressed. We were both happy and excited though, I reckon Sirius will be bridezilla though,"

"Hmm," Regulus hummed in agreement,

"Thank god we've these horcruxes to worry about first," James joked.

"Because finding and destroying the horcruxes will have nothing on prewedding Sirius," Regulus chuckled,

"When they've had their day we should do it again,"

"What you mean marry again?" Regulus raised his eyebrow.

"Yeah babe renew our vows, have a day that hasn't been tainted."

"James Potter, are you proposing again?"

"Wait no this is a terrible way to do it this isn't that romantic pretend I didn't say anything and then act surprised when I propose we renew our vows," James spluttered. Regulus chuckled,

"I don't know cuddled up with you like this is pretty perfect," Regulus traced circles with his thumb onto the back of James' hand.

"Reggie, can you imagine telling Sirius that he'd string us up and say we're stealing his thunder. Let me ask again in a better way please and when Sirius and Remus have had enough time to soak up their newly engaged joy," James pleaded.

"Okay baby," Regulus caved, bringing James' hand up to his mouth and kissing it softly. They drifted off to sleep after talking about leaving Harry with Pandora and going to an art museum to get time away from the park. At exactly two in the morning they were woken up by Harry screaming,

"What the hell," Regulus croaked rubbing his eyes, "James get up Harry is crying hard," he nudged James.

"Wh-what, that's odd Harry usually sleeps through the night now," James stretched over to grab his glasses and put the light on while Regulus covered his ears. "Harry, honey what's wrong," James cooed, getting up to go over to Harry's travel cot. "Melrin, fuck, Reg, he's all red," James screamed. Regulus shot up, jumped out of the bed and walked over to Harry. Harry seemed to have a red rash all over his face and neck. Regulus lifted him out of the travel cot and stripped him so that he was only wearing his nappy. He had a red rash all over his chest and arms too and his throat looked a bit swollen. Regulus ran his fingers over Harry's chest; it felt like sandpaper.

James went to take Harry out of Regulus' arms but Regulus held Harry close so James could not,

"Reggie baby, I am worried what is wrong with him?"

"I don't know, I don't know, we need a healer," Regulus felt hot tears spill out of his eyes, "Harry, it's okay, it's okay darling," he soothed him while bouncing him on his knee.

"I don't know where any healers are,"

"Well shouldn't we have thought about that before taking him to a different country," Regulus snapped.

"I didn't think this would happen! Oh fuck Reg, what are we going to do. It's not like we can ask,"

"Fuck sake, let me think," Regulus snapped again. James tried to take Harry from Regulus' arms and Regulus turned around so he couldn't. Harry was sobbing into Regulus' chest, "Oh honey, it's okay, papa is going to make it better," Regulus cooed .

"I'm going to get Remus," James breathed. With that James got up and pulled on some clothes and left to get Remus. Regulus started examining Harry, trying to think if he he'd seen this in any book he read but his mind wasn't working, he wasn't a healer though he was interested in that line of work, he had read many books but his mind wasn't working he was just asking whatever was up there to make sure Harry was okay and nothing happened to him he couldn't deal with it if anything happened to Harry. He didn't want to think about what James would be like if something happened to Harry.

Remus, Sirius and James came through the door. Sirius seemed drunk but Remus had a very high tolerance so he seemed okay. Remus tried to lift Harry, but Reg snuggled him closer,

"Okay, okay, I won't take him, I just want to see him," Remus said, holding his hands up. Regulus held a weeping Harry out so Remus could take a look at him.

"I think it would be worth taking him to a muggle hospital," Remus announced,

"Are you sure Moony?" Sirius slurred.

"Yeah if I'm correct he can be looked at by a muggle 'doctor'," Remus announced.

"Well you better fucking be right," Regulus lashed out. He sat Harry down on the bed to get into clothes and no one dared lift him and then once he was dressed he lifted him and they headed for the nearest muggle hospital.

Regulus held on to Harry tightly the whole way in and went up to the desk the other four boys trailing behind him and he began to explain his symptoms to the lady, she was talking about taking a seat,

"What? Take a seat? No go get someone to see to my son!" Regulus' eyes flashes dangerously. Regulus barely noticed but James was smiling very wide. This may have been a terrible situation but he never heard Regulus refer to Harry as his son before, probably because Regulus never had said it. Just two words, 'my son' and James' heart was soaring. The woman was being argumentative with Regulus but you see you don't fuck about when it

comes Regulus Potter's kids. Regulus slipped his hand into his pocket and pulled out his wand not raising it keeping it quite covered and with James, Sirius and Lupin behind him no one could see it from that end too, he muttered 'imperio' and a doctor was brought it a matter of minutes.

Harry was seen to and they were told he had scarlet fever and would need antibiotics, lotion and to make sure he had plenty of fluids. He was going to be fine though his son was going to be fine.

Sirius

James, Narcissa and Sirius drinking sat on the plane on the flight home. Pretty much everyone else had fallen over to sleep apart from them, Harry, Draco and Luna. Draco and Harry kept reaching over to give each other little hugs, Sirius' heart swelled with fondness of the two boys getting on so well, Sirius imagined they would now be friends for life and honestly there wasn't an idea he loved more. Luna was strapped to her mother babbling to herself as Pandora snoozed lighty in her chair. Thankfully after the scare with Harry having Scarlet fever meant they had to stay in Florida until he had recovered. Sirius was glad, he was worried about him, they all were, but looking at him now as he played with Draco put them all at ease.

"Cheers to a successful holiday," James said with a smile as he lifted his little plastic cup of Jack Daniels and coke. Narcissa and Sirius laughed at him as the three of them clinked their little cups together.

"We should do shit like this more often," Sirius answered and James nodded at him.

"Well once we are done of course," James replied and Narcissa looked at them confused.

"Done?" She questioned and Sirius shook his head.

"Never worry about it Cissy," He smiled as she took a sip of her red wine.

"A secret mission?" She laughed.

"I guess you could say that yeah… nothing for you to worry about," James smiled.

"Did someone remember to pack my Mickey mouse ears," Sirius suddenly said, jumping up and pulling his bag from overhead.

"I'm sure Lupin would have yeah," James chuckled.

"Mickey mouse," Draco and Harry chanted as Sirius searched his bag.

"He's worse than the kids sometimes," Narcissa laughed.

"I paid good money for those Cissy," Sirius said in a stern tone, "Moony! Moony wake up, where are my Mickey mouse ears?" Sirius said as he shook Lupin awake. Lupin's eyes snapped open.

"What is it? Is everything ok? What happened?" He said in a startled tone, he was clearly still half asleep. James just shook his head at Narcissa.

"I think it's time for another drink," James said as he pressed the little button above his head.

"You woke me up to put on a headband with a cartoon mouse' ears on them," Lupin huffed and rolled his eyes at Narcissa and James.

"Of course I can't find them! Where are they?" Sirius said in a pained tone and Lupin sighed as he stood up and brought his own bag down.

"They are here!" Lupin snapped, "You would think you were five," He continued and Sirius smirked.

"My lovely Moony mentally I am 14 and not a day older, forever young at heart" Sirius laughed as he placed the headband on his head, "and don't try to deny how cute I look right now," Sirius smiled and Lupin rolled his eyes.

"Christ Sirius you make it seem like you're about 80 years old," Lupin laughed, "I think you may have had a bit too much to drink," Moony replied and Sirius shook his head.

"On the contrary my moon, I have only had three drinks so far," Sirius laughed as he placed a kiss on his fiance's lips.

"Maybe it's the altatured going to your head," James laughed and Sirius shot him a playful look.

"You're just jealous that you're a dad so you have to be responsible now" Sirius replied and James just shrugged at him with a smile.

"Ears EARS EARS!" Draco and Harry called pointing at Sirius' head.

"You guys want my ears?" Sirius laughed and the two boys nodded excitedly.

"EARS!" They called again.

"Harry inside voice," James said softly to Harry, but he didn't seem to be listening to his dad. Sirius just chuckled to himself.

"Sirius give me the ears please," Regulus chimed in, causing Sirius to jump.

"I thought you were asleep," James said to him.

"I was but the screaming children looking for the toy off their uncle woke me up again," Regulus laughed.

"Fine, here you guys can have them," Sirius laughed and handed them to Draco and Harry who began pulling at them. Sirius stood up and stretched, "I'm gonna go take a piss," Sirius announced and Lupin and Regulus rolled their eyes.

"Fuck sake Padfoot do you have to be crude," Lupin huffed and Sirius nodded.

"I don't think he's capable of manners," Regulus sighed.

"That is because dear brother mother beat manners into us so in order to annoy her further I refuse to play by the rules," Sirius replied in a matter of fact tone, with a wink.

"Go to the bathroom pads before Lupin and Regulus knock you out," James said to him, "I'll come with you I need to go as well,"

Sirius and James made their way to the bathroom at the back of the plane. Sirius went in first and used the bathroom and then let James in. Once the both of them had finished Sirius stopped James outside the bathroom before going back to their seats.

"Listen James congratulations again you know about the baby honestly man I'm over the moon for you guys," Sirius began and James smiled at him as he placed his hand on Sirius' shoulder, "I am really happy for you guys really, especially Regulus, no one deserves this more than him and I can already tell from watching his with Harry he's gonna make a great dad," Sirius continued and James just looked at him with tears of happiness in his eyes.

"Thanks Pads, that means a lot," James began, "You're right Regulus deserves this and the world," he continued, "And I know he's going to be the best dad, gonna put even me to shame," James laughed and Sirius smiled.

"However even with all the good news I feel like it needs to be said… James my man, have you ever heard of a contraceptive spell?" Sirius' voice had changed now as he spoke to James, "I mean all these unplanned pregnancies? And of all the times for it to happen it's when we are on the hunt for these fucking things," Sirius snapped and met James eyes. James opened his mouth to speak but Sirius shook his head, "James do you really think this was the best time? I mean we have been living in a tent and it's bad enough we already have Harry but now Reg being pregnant I mean on the hunt is no place for someone pregnant," Sirius continued and James nodded his head.

"I know Sirius and it really was unexpected …. I mean we were going to wait really we were but-" James began but Sirius sighed.

"But what James? I want nothing more than for Regulus to get the life he deserves and I know a baby is what he wants but you couldn't have kept in your pants until this was all over?" Sirius barked, causing some people to look at them.

"Sorry," James muttered, "Sirius I know, but he was already pregnant before all this was happening but I'll look after him and keep him safe I promise," James answered. Sirius sighed again and rubbed the back of his head.

"Damn fucking right you will or you'll have me to deal with," Sirius answered and James nodded.

"I don't doubt it," James laughed nervously. Sirius smiled at James and patted his shoulder.

"Let's get back to our seats before they think we are taking drugs in the toilet," Sirius laughed and James chuckled.

Once they had made their way back to their seats James cozied up beside Regulus, with Harry on his knee and the three of them fell asleep. Sirius had a couple more drinks with Narcissa before she announced she would be taking a little sleep as well and Sirius nodded in agreement as he curled up beside and took a look over at Draco and Luna who had dozed off in their seats. Sirius looked round at his friends and smiled to himself. This was the perfect end to the best holiday he had ever had, he had thought to himself as he drifted off because his husband to be.

A few days after they had arrived home from their holidays. The four men were back out in their tent, trying to hunt down the next horcrux. Harry was having his afternoon nap. Each one of them scribbled down on pieces of Parchment.

"Ok we have four owls so what letter are we sending out first?" Sirius asked.

"I've written one to send to Lucius asking what he knows about Voldemort's childhood if he knows anything," Regulus began and placed his letter in an envelope.

"I wrote one to Dumbledore, if anyone knows anything it'll be him I would say," Moony answered.

"Dumbledore good shout," James answered and placed his own letter in an envelope, "Do you think Malfoy will reply?" He continued and Sirius looked to Regulus.

"If he doesn't, Narcissa will make him and anyway Lucuius likes to have people thinking he's more important than he is so if he knows anything he'll be bursting to tell someone," Regulus said.

"He couldn't hold water in a bucket," Sirius laughed.

"We need to know as much as possible everything is important to try and find these things to get rid of them," Moony said and the three of them nodded at him, "Even if it seems silly we need to look at everything we learn about him," He continued as he tied his own letter to his owl and sending it on it's way.

"Once these owls return we will send more letters to anyone we think might be able to help," Sirius sighed and stretched his hands.

"How many do you think there are?" James asked and Sirius shrugged as he looked at his brother.

"I have no idea," Regulus replied.

"There will be at least three or four so we'll focus on them to begin with and as more information comes in we'll work on that," Moony said.

"We could be at this forever," Sirius moaned.

"We won't be," Regulus replied, "We'll find them and get rid of them," He continued as James wrapped his arm around his boyfriend.

"We'll make sure he's never able to come back," James said in a stern tone, "Make the world a safer place for our baby and Harry," he finished and Regulus smiled.

"It just makes a skin crawl that at any moment he could come back," Sirius interjected, "and if he does we'll be right back to square one," Sirius spat and Lupin nodded.

"I know Sirius but like James and Regulus said we're going to make sure that doesn't happen," Lupin answered him.

"We have to do it for Lily and all the other people that he or his followers murdered," Siirus continued, "We wont let them die for nothing," He spat and the room went silent.

After a few moments of quiet James stood up and held his hand out for his husband and almost as if on cue Harry began to cry in his room. Regulus took James hand and stood up as he went to get Harry from the room. James just smiled at Sirius and Lupin.

"I think we are going to go into town for some food, you guys up for it?" James asked and Sirius shook his head.

"Just bring us back a doggy bag," Lupin smiled at him as James nodded. Shortly after Regulus had gotten Harry changed, James and Regulus left with him to get food in town. Sirius jumped up from his seat and walked into his and Lupin's room and began rummaging through the dresser drawer.

"What are you looking for?" Lupin called in and Sirius smirked to himself as he lifted out the collar and dog lead and made his way back out to the living room.

"I thought we could have a little fun while we have the place to ourselves," Sirius smirked as he lifted his eyebrow. Lupin's eyes snapped to the lead in Sirius's hand and then to his face as a wicked glint came into his eyes.

—--SMUT--

"Feeling a little bit excited are you?" Lupin questioned as he stood up and made his way to Sirius. Sirius' stomach did a little flip as he turned and walked back into the room. Lupin followed behind him. Once in the room Lupin grabbed Sirius from behind and began biting lightly at Sirius' neck. Sirius let out a little moan as Moony's hands ran all over his body. Sirius pushed himself up against Lupin's cock which Sirius could feel was just as excited as him. Lupin reached down as he kissed Sirius' neck and took hold of the collar from Sirius' hand. Sirius gave it up easily as Lupin pulled back slightly and began to put the collar on Sirius. Sirius could feel his body vibrating with anticipation as Lupin pushed him down onto his back on the bed and climbed on top of him, tightening his grip on the lead. Sirius arched his back as Lupin crawled between his legs and their lips met with hunger. It was hard as Sirius tried to pull at Lupin's clothes.

"Ahh not yet," Lupin growled and Sirius felt himself stiffening in his own trousers.

"Please Moony," Sirius moaned and kissed down his Fiance's neck. Lupin sat back on his knees and pulled Sirius T-shirt over his head and threw it to the ground beside their bed.

"You know I love it when you beg," Lupin moaned and Sirius arched his back, reaching down and tugging his trousers off as Lupin did the same with his own clothes. Sirius now lay on the bed fully naked with only a lead and collar on. Lupin stared down at him hungrily.

"You're so beautiful,' Lupin smirked as he ran his hands down Sirius' naked chest causing Sirius to let a moan slip from his lips, "Fuck your breath taking," He contined as he drunk in the image of Sirius. Sirius smirked and rolled round so he was on his hands and knees.

"Fuck me Moony- Hard," Sirius groaned as he pushed himself back against lupin who gave out a sugh of pleasure. Lupin then tugged on the lead causing Sirius' head to bend backwards as Lupin entered slowly inside him. Sirius gave out a loud moan as he felt Lupin inside him.

"Moan for me Sirius," Lupin growled as his pace quickened. Sirius' body felt like it was on fire from pleasure as he moaned loudly, grinding his hips against Lupins as he thrusted inside him. Sirius could feel himself building, Lupin had leaned forward and was trailing kisses down Sirius back, which made his stomach flutter.

"Fuck Lupin, Your so good," Siirus said breathlessly as the sweat began to drip from his body. Lupin was thrusting harder and Sirius reached down and began to stroke himself. Moaning louder with each thrust.

"Sirius," Lupin moaned as he pulled on the lead, Sirius felt the collar tighten on his neck which only heightened his pleasure. Both men were breathing heavily as they inched closer to their orgasm, "Who do you belong too?you dirty dog" Lupin said breathlessly.

"You and only you," Sirius answered in a moan. Lupin slapped Siirus on the buttock as he slid in and out him. Sirius didn't want this to end.

"I'm gonna cum," Lupin breathed out as he began to go faster and harder.

"I'm so close," Sirius replied as he gripped the bedsheets with his free hand. Sirius knew he wasn't going to last much longer. He was on the edge.

"I want you to cum with me Sirius," Lupin breathed and Sirius moaned as he finally felt himself explode onto his hand and the bed. Lupin gave one last hard thrust before he collapsed over Sirius' back. Sirius could feel Lupin emptying himself inside him. Sirius legs gave way from under him and he landed face down on the bed breathing heavily, Lupin rolled off him and lay beside him, pulling the blankets round them.

"We need to do this more often," Sirius breathed with a laugh.

"We do and I have to say that collar and lead fits you perfectly," Lupin breathed and pressed a kiss on Sirius forehead. Both Sirius and Remus then dozed off into a sleep, intertwined together.
