The Perverse Rot of the House of Black by SiriusBlacksTwinkBrother
Fandoms: Harry Potter - J. K. Rowling
20 Feb 2026
Tags
Summary
“Come on, just one peek, please,” James whines, tugging on Sirius’ arm. “He’s asleep, and he looks so gorgeous like this. All soft and cock-drunk.”
Sirius groans. “Jamie, for Christ’s sake. We get it, you're smitten with a bloke you fucked once.”
James drags them to the bedroom anyway, excited to show off his new toy. One glance at the boy in their sheets and Sirius goes pale.
Remus steps closer, frowning. “James,” he whispers. “I… I think that’s Sirius’ brother.”
Or: Sirius is the ruthless head of his family’s criminal empire. His lovers, James and Remus, stumble upon Regulus—Sirius’ estranged little brother. But in the House of Black, obsession breeds like rot, and none of them are willing to let him go. Not when he’s so damn pretty, chained to their bed.

Summary
"Tell me, Black, have you ever kissed a man before?"
When Sirius Black ran away, he left behind more than just a house, he left a brother to drown in the silence of Grimmauld Place.
James Potter has always been the boy who gets what he wants. He wanted the Snitch, he wanted the Cup, and for years he wanted the girl. But then he truly saw Regulus Black. Not as Sirius's little brother, but as someone strikingly beautiful and dangerously captivating. Regulus became the new, unreachable challange James could'nt ignore.
What starts as a reckless pursuit soon turns into a dangerous game of whispered promises in moonlit corridors and secrets that could burn the wizarding world to the ground. As Voldemort's shadow grows, James and Regulus find themselves caught between loyalty to their blood and the fire between them.
In a war where everyone must choose a side, they chose each other. But the price of choosing a Black has always been paid in blood.

Summary
“You’re going to let Jamie fuck you,” Lily continued, voice mild again, idly twisting the plug as Regulus shook. “He’s going to come in you, and then-” with the heel of her hand, she sank the plug home “-you’re going to put this right back in.”

The Hunter And His Prey by SiriusBlacksTwinkBrother
Fandoms: Harry Potter - J. K. Rowling
13 Dec 2025
Tags
Summary
"Why would I drink from this bag," James purrs, "when I have you, sweetheart? My willing little living blood bag."
Heat floods Regulus' cheeks, shame and desire tangling in his chest. "I'm not—" he starts, but James cuts him off with a finger against his lips.
"Aren't you?" James whispers. "You came here willingly. You knew what I am. What I do." His fangs descend, tracing the line of Regulus’ throat. "Your heart is racing, little star. Is it fear... or anticipation?"
Or: James Potter is an ancient pureblood vampire—gorgeous, powerful, obscenely wealthy and, most dangerous of all, bored. He finds his newest entertainment in the worst possible place: taking wicked delight in corrupting vampire hunter Sirius Black’s younger, painfully innocent brother, Regulus.

Summary
They weren't always like this. For a long while James was simply a silent viewer, fist around his cock and eyes reverent as he watched Regulus get fucked. They'd hammer into him bent over the arm of a sofa, face down on a mattress, knees positively murdered on a kitchen floor. James wasn't in love with Regulus then. It's kind of ridiculous that some men believe themselves to be in love with Regulus still. They've never met him, have no idea how salty he tastes, how heavy he is on a tongue, how precious he is in the afterglow. They've never seen him lounge around a sitting room in nothing but a pair of boxers, nose buried in a book, lip trapped between his teeth as he pores over a study guide. They've never truly been in love with Regulus.
Or: an unnecessarily long "pornstar", "free space", and "doctor/research assistant" bingo entry.

Summary
Regulus runs his fingers over a familiar set of leather cuffs and hums under his breath.
“You like?” James asks, leaning against the headboard beside Regulus.
“I have the same pair in green.” Regulus tells him.
James sits up a bit straighter. “They have them in colors?” He asks excitedly.
----
or: James and Regulus have a blissful afternoon shopping for new toys together.
(stand-alone one shot, but in my head it’s also a part two for ‘out of focus’)

Southern Hospitality of Possessive Perverts by SiriusBlacksTwinkBrother
Fandoms: Harry Potter - J. K. Rowling
30 Nov 2025
Tags
Summary
“Of course, Mr Black. Would you like a room with one bed or two?” the hotel attendant asks.
Sirius’ gaze shifts across the lobby until it lands on Regulus—his much younger brother, too pretty for his own good, fifteen years his junior and painfully naive to the world’s worst intentions. He notices the swell of his chest, the indent of his nipples against his shirt, and the faint outline between his legs—a subtle, unmistakable curve hinting at what lies beneath.
He swallows. “One bed please.”
Or: Sirius has a sick, perverted obsession with his younger brother. When he discovers Regulus has slept with cowboy Remus Lupin—somebody tall, roped tight with muscle and double his age—Sirius can no longer keep his dirtiest, most possessive desires buried where they belong.

Summary
"Good morning my little star" was the first thing regulus heard as he slowly woke up. Then next thing he noticed was the feeling, something sharp and cold under his chin a hand slowly sliding down his waist. "Stay very still little star" his boyfriend James said. Well. This is going to be a interesting morning regulus though, not that he was minding one bit.

Summary
Each word is a thread, gently stitching Regulus back together, pulling him in from wherever he’s floated. His vision flares white, then blurs into gray. His throat feels impossibly tight, as though the world could seep in around him in a thin trickle of pain. He fights. Against the gag. Against the tears. Against every scratch of fear that claws at his edges. But beneath it all is something teetering on euphoria: the fierce awareness that he is meant to be here. That this is his reckoning and his reward.
_____Regulus exhales slowly. “You want me to bleed for you before you’ll bruise me.”
James’ jaw tightens—but not in frustration. In recognition.
“Yes,” he says. “That’s exactly it.”
