“What is…” Sirius slid his leg back and forth between his sheets again, his foot catching on a stray piece of fabric again. He hooked it over his toes before dragging it up to the opening and transferring it to his hand.

It was a pair of boxer briefs, green with a grey waistband, and definitely not Sirius’.

“Regulus!” Sirius called, not wanting to get out of bed, and knowing his younger brother was still awake in his own bedroom. “Reggie, come here!”

“What?” Regulus asked as he stepped into the doorway, expression and tone equally bored. He was dressed in nothing but a pair of pajama pants, a book in his hand with his index finger squished between the pages to hold his place.

“Why are your underwear in here?” Sirius asked, holding up the offending article of clothing to show Regulus. There was a damp spot at the front, dark and stiffening, as if Regulus’ cock had been leaking at the tip before he finally kicked them off, like maybe… “Did you fuck someone in my bed?”

Sirius willed his heart rate not to spike at the visual, silently begging his own dick not to grow hard at the thought of his brother writhing around in the exact spot he was currently laying in.

A blush crept up Regulus’ cheeks at the accusation, but he shook his head all the same. “No, Sirius,” he said, tone suddenly patronizing. “I didn’t fuck someone in your bed.”

Sirius looked at the underwear in his hand, thought about the way they had so clearly been pushed off under the covers in a fit of rushed desperation, and wondered if Regulus had left them for Sirius to find, or if he had simply forgotten them.

“Did you—” Sirius felt his voice break and paused to take a deep breath to steel himself. “Did you jerk off in my bed, Reggie?”

Regulus let out a soft, embarrassed laugh, looking away from Sirius’ gaze. “Of course not, Sirius.” The words were soft, devoid of emotion, and clearly a lie. Regulus wasn’t trying very hard to hide the truth of what he had done.

“Why in my bed?”

“It smells like you,” Regulus replied, his blush spreading further down his face and across his bare chest, but there had been no hesitation in the words.

Oh fuck.

Sirius clenched his eyes shut and dragged in another deep breath. His heart was racing, even as he felt all of his blood rush to his cock at the insinuation.

“You think about me while you touch yourself?” Sirius asked, opening his eyes to look back up at Regulus. He knew his own pupils would be blown wide, lust-crazed and desperate, but it was Regulus that had started this. It was Regulus’ desperation that had led Sirius to realize the thrumming need under the surface of his skin, and Sirius knew Regulus wouldn’t reject him.

Regulus sucked his bottom lip into his mouth and nodded his head. “I can only come when I’m in your bed.”

Regulus could only finish when he felt close to Sirius, when he was surrounded by his scent and his belongings? What would Regulus’ orgasm be like if he came with Sirius in the bed with him?

“Show me,” Sirius said, tossing the underwear to the side and scooting over to make room for his brother. “I want to see your pretty face when you come on my sheets.”

Regulus’ breath audibly hitched. He tossed his book onto Sirius’ dresser before stepping further into the room, all bashfulness just as forgotten as the page he had been reading.

Regulus grinned, a sultry, sexy thing, before sliding his pajama pants down his legs and kicking them off to the side.

“Make me, Siri.”

Sirius: Sorry I’m late, I was doing things.

Regulus: Hi, I’m ‘things’.

Let's face it, in a fight between Sirius and Regulus neither would win. Not really. Sirius would never hurt Regulus on purpose, and neither would Regulus. And Regulus is also a sneaky little shit who would play dirty because he's a Black, a Slytherin and Sirius's little brother. He'd climb on his back, cover his eyes, tickle him, even bite him. Sirius would shake him off, flatten himself against the wall to get him off of him and then throw him onto the bed. He'd start tickling him, get back at Regulus by biting him. Sirius would continue tickling Regulus, while asking him if he'd finally given up, Regulus would say no, which would only make Sirius tickle him again and end up climbing on top of him. It would finally end with both of them staring into each other's eyes with a full smile on their faces, only for Sirius to decide to quickly move away so as not to give in to the impulse to kiss his little brother.

Awwww fluffy starcest 🥹

Personally I love having them fight like cats and dogs 😂 absolutely viciously; hitting, kicking, hair pulling, biting, scratching, clawing, anything to get the upper hand. Not so unevenly matched because although I love a taller, more muscled Sirius, I think Regulus makes up for the smaller stature in pure spite and mercilessness— he’s ruthless and savage because he has to be, to stand any chance against his big brother

Of course, it always ends the same way, fucking 😝

Ask time!

Top 5 HP universe ships and why you like them?

Thankyouthankthankyou! Saving me by sending an ask. 💚💚💚💚💚💚💚💚💚💚💚💚

In no specific order because I can't pick. 1) Severus x Lily/Snily ✨ Why do I like them? Sev is a top fav for me and I feel for him and also feel for his tragic life, and his fallen relationship with Lily. It hurts me soul and I like them having a chance in fics/arts. Whether romantic or just sticking as best friends! 2) Severus x Sirius/Snirius/Snack/StarPrince🌠 Both Sev and Sirius are my top favs, both clashing in spot number 1 and I refuse to pick. And it only make sense to ship them. And given their history but it's esp interesting post Azzy when Sirius is free. Two broken men trying to either break each other some more or find solace in each other. 3) Sirius x James/Prongsfoot/Bambibelle/Starbucks/Should be called Starchaser but whatever, I digress 💫 JAMES POTTER. Enough said. Hahhahaa. Best friends! Who were obsessed with each other much? Like oh my gosh. These lil shitface nerdy arrogant cuties. They are so fun but heartbreaking. 4) Sirius x Regulus/SiriReg???Blackcest/Starcest/What? ⭐ I am a fiend, *points at username*, I love these types of ships, hahahhaa. Also Reg is a fav because I love the Black Family. Just brotherly love loving each other mayhaps a bit too much. 5) Severus x James/Jeverus/Snotter (hahaha), PrinceBucks(?) 🌌 I wanna say it was my first marauders era ship. It reflected Drarry to a degree, despite not shipping it as much as I sued to before Sirius stole part of my soul. Funny, I actually used to 'hate' James so I'd mainly go to fics of James being a complete ass to Sev. It shifted cuz I like variety. (I DO! Ignore the fact that these list mainly has Sirius or Sev focused ships!) I can feel like an oddball, even though I know I am not and with this new wave of young fans (who don't even read the wiki of HP), it feels like enjoying both the marauders and Snape clash. Honestly, even before. Anyways, thanks for the ask, I hope I answered well!

“There’s nothing wrong—” James swallowed hard, trying to think of the right words to reassure his best friends. “You’re both perfect,” he whispered.

Sirius shook his head. “You weren’t supposed to know about this,” he said, attempting to shield Regulus’ naked body with his own. “About us.”

James loved Regulus and Sirius more than anyone in the world, and he didn’t understand why they would have hid their relationship from him. It didn’t matter to him that they were brothers — not if they made each other happy.

“You don’t think there’s something wrong with us for wanting to be together?” Regulus asked, and his voice sounded so small, like he was afraid of how James might respond.

Stepping closer toward the bed, James reached around Sirius and cupped Regulus’ face. “No, Reg,” he said, shaking his head gently. “You’re beautiful together.”

James heard the roughness of his own voice, the way it was growing deeper as it always did when he was turned on, and he could only hope the brothers didn’t notice. This moment wasn’t about how sexy they were, naked in front of him — it was about their love for one another, and James’ unending support.

“You like us together,” Sirius mused, one side of his mouth tipping up into a smirk. Clearly, James’ arousal hadn’t escaped his notice at all.

At least it took some of the tension away, James supposed.

“Wait,” Regulus added, and James could feel his cheeks pink at the knowledge that Regulus had caught on too. “You’re turned on by this.”

It wasn’t a question, but James shook his head in refusal anyway.

“I can see the proof right here,” Sirius said, reaching out and cupping James’ hard cock through his pants. Sirius grinned at Regulus before they each grabbed one of James’ hands and tugged him down onto the bed to join them.

OTP? I can't pick one so will give my tops: Snirius, Snily, Prongsfoot, Jily, Jeverus, SiriReg~ 2) OT3? Any combo of the above, hahahaha, oh, oh! Wolfstarbucks!!! I loooove that ship so much. Feed me fics and art of it, I beg you. 10) What's your favourite piece of fanart for [character]? Ignore Reg, love him but the focus is Sirius looking soooo fine. Here I love canon Sirius, him being tall, masc (no not like hyper macho masc), hair not so curly, defined face looking elegant yet not delicate. Also @arliedraws draws a mighty sexy Sirius. 20) When did you first join Tumblr? How long was it between that and finding [fandom]? I...don't recall. It has to have been between 2010-2012. And did ya mean finding HP fandom? I wanna say I joined HP fandom 2014, yeah. Hahahhaaa. I didn't do much aside reblog and read fics, didn't interact or make stuff for it until some years later like 2018.
