the knife in my back isn't knife-shaped (actual title pending)
Summary
Regulus Black felt indisputably and magnificently alive. Was he a little drunk? Of course, but everyone was. Were his fingers split open and painting the strings of his guitar crimson? Also yes, but it wasn’t like he could feel his hands anyway. Was he probably going to lose his hearing before age 30? No comment.To sum it up, Regulus Black was in his element: every pair of eyes in the stadium were on him, and he'd be damned if he didn't give his fans the show they deserved.OR Anarchists for Entropy (truly the pinnacle of angst) is quickly rising to fame and rapidly gaining followers, the band consisting of Regulus Black, Barty Crouch, Evan Rosier, and Pandora Lovegood. After his brother left when he was eight, Regulus drowned himself in music, and hasn't heard from the man since. Good riddance.BUT a series of incidents with a TV channel, a book club, a threesome, and James Potter's stupid smile have Regulus Black hungry for revenge and the man Sirius calls his "best friend."(Basically Regulus is in pain and Sirius makes things worse and then things get a little better but I'm bad at summaries so plz ignore me)

Chapter 15

James Potter had a big dick. It wasn’t surprising to Regulus—Potter was tall and fairly muscular—but he hadn’t anticipated just how much James’ dick would fuck with his hips. His entire abdomen ached, but it wasn’t in an entirely unpleasant way. He was glad, however, that he had a break before the next concert, and he knew it was embarrassingly obvious what’d they’d been up to the previous night when he hobbled from James’ car to the hotel, limping and covered in hickies.

Barty was on him as soon as he opened the door.

“Well, well, well. Someone had fun last night,” he sneered, raising an eyebrow at Regulus’ neck. Regulus pulled the neck of his sweatshirt up.

“Worth it,” he grinned, flopping onto the bed.

“Evan and Pandora went to work some shit out for the next show. They should be back within the hour,” Barty said when he saw Regulus peering around the room. “Until they get back, though, how’d it go with Potter?”

Regulus definitely wasn’t blushing. Nope, not at all. “I think he broke my pelvis,” he muttered, stretching with a groan.

Barty snorted, “big dicks tend to have that effect.”

Really big dicks,” Regulus said. Barty rolled his eyes.

“You two exclusive?” He asked, and Regulus didn’t think Barty could be any less subtle.

He pulled the covers over his head and closed his eyes. “You’re more desperate than I am, Barty. I’ve fucked the man once—I’m not proposing a gangbang before I’ve even sucked him off,” he said.

“It’d break the ice, I reckon.”

Regulus didn’t dignify that with a response.

[James POV]

 

James wasn’t entirely sure how it happened, but he’d noticed a pattern: if Regulus wanted something, he got what he wanted. James was more than happy to uphold the pattern, so he supposed that was probably how they got where they were.

We’re going to spoil you rotten, baby,” he whispered in Regulus’ ear, pulling the man’s ass backwards until he was slotted against James’ dick.

Evan huffed a laugh. “Isn’t he just the most obedient little slut? He’ll do anything if you promise to dick him down.” He laughed again and Regulus whimpered.

Truthfully, James had been incredibly hesitant about a foursome with Evan and Barty, though admittedly, a great deal of that hesitancy stemmed from jealousy. Evan, Barty, and Regulus had been a team for years, and everyone could see their undeniable chemistry onstage. But the thought of it, the image of Reggie fucked full of cum in every hole, kept appearing in his dreams. He’d wake up hard, and if Regulus was there, he’d wake the younger man up by sliding into his still-wet cunt, fucking them both awake.

Another thing was Regulus’ incredible stamina, and unlike James, he could have multiple orgasms, like a chain reaction. He could go again and again until he was panting and sobbing from overstimulation and James was dead tired. James wasn’t complaining about it, of course, but in the back of his mind, he wondered how long the younger man could go for if there were six hands on him, filling him, teasing him—

“Y’know, he can fit two dicks in his tight little cunt,” Barty said when James’ fingers slipped between Regulus’ legs.

James’ hand froze on the man’s clit and he glanced at the two married men. “He’s taken both of you at once?”

Barty grinned. “You should hear how loud it makes him scream,” he said, and all the blood in James’ body rushed to his dick. Holy shit. “I wonder how loud he’d get if you and I fucked him together?”

James was lightheaded with desire. Was it even possible for them both to fit?

Regulus, whose mouth was filled and gagged with a muzzle, whined, his eyes squeezed tightly closed.

The idea of a foursome—or a “gangbang,” as Regulus so eloquently put it—wasn’t something Regulus mentioned, but rather something James hinted at. He knew Regulus would never bring it up, but he had no doubt it was something the younger man would enjoy. James had been deep in Regulus’ throat when he growled about how much Regulus would love all his holes filled at once, to be utterly used. Regulus came untouched, which James hadn’t known to be possible. James learned new things about the limits of the man’s body every day and it was incredible every time.

After many conversations and discussions, they decided on rules and limits. Most importantly, Barty and Evan could join them, but James got to dictate the pace of the scene. When he couldn’t speak, Regulus could tap out by snapping twice or tapping whoever was nearest twice. A part of James was glad Evan and Barty knew Regulus so well, because he knew they’d all be able to recognize immediately if Regulus began to drop.

So, James was behind Regulus, teasing his cunt open, while Evan and Barty alternated between watching, making out with each other, and sucking dark bruises into Regulus’ skin.

The man of the hour was muzzled—a contraption James had bought special for Regulus with a matching collar—and Barty had surprised them all with a leash made of heavy, smooth leather. Whenever Regulus’ hands got a bit too adventurous, James would tug on the leash and Regulus would whine so pretty.

James was sitting on the bed with Regulus in between his knees, the younger man’s back against his chest. James had Regulus’ thighs hooked around the outside of his knees to keep the man’s twitching legs open wide. He was four fingers deep in the Regulus’ soaked cunt, and upon Barty’s insistence, he scissored his fingers open and gradually worked a fifth finger in. Barty and Evan were right—Regulus could take much more than James previously thought.

His fist slipped in, despite the awkward angle, and Regulus keened, his entire body trembling. He’d been given strict orders not to cum until given explicit permission, and they’d been edging him mercilessly for the greater part of the last hour.

Tears streaked his face as James set a rhythm with his fist, and the obscene sounds of Regulus’ arousal filled the room.

When he removed his fist, slick connected his fingers like webbing and he used them to lube his dick. The bed below them was already drenched, but James couldn’t find it in himself to care as the head of his dick popped into Regulus’ pulsing cunt. He pushed in slowly, easing his length into the younger man one inch at a time.

What a good pet you are,” James whispered when he was fully inside the man. Regulus moaned and more tears dripped down his pretty face.

“He was made to take cock, look at him,” Evan said, pinching Regulus’ nipples and earning another choked moan from the man.

Barty, not one to be left out, took Evan’s words as permission to speak. “Do you feel full?” He asked, and when Regulus gave a shaky nod, he sneered. “Too bad we’re nowhere near done filling you up, doll.”

Regulus shivered and James felt Barty’s hands next to his dick on Regulus’ hole. James stilled inside Regulus and the younger man whined, squirming when James didn’t make any effort to move again. He squirmed harder when Barty slipped a lubed finger into his stuffed hole.

He was whining louder now, his eyes wide, but he had yet to tap out, so Barty pressed another finger into him, slowly so as to not seriously hurt the man. James grit his teeth and focused on not cumming on the spot as the pressure around his dick increased with each of Barty’s fingers.

“Such a pretty fucking whore, isn’t he?” Evan drawled, lifting his blown-out pupils to look at James. Between the three of them, they’d established a dynamic: Barty was hardest and cruelest, Evan was best at backhanded praise, and James was soft but firm. James had to admit—they worked well together. Especially when Regulus had fought against the muzzle at the beginning of the scene and Barty slapped him cherry red while Evan egged him on and James held Regulus still and forced him to take it, growing harder with every drop of slick that dripped from Regulus’ messy cunt.

Barty was up to three fingers, and Regulus was a broken record of muffled whines. “This is gonna hurt, baby, but you’re going to take it.” He lathered his dick in a generous amount of lube and lined up next to James.

Regulus was squirming again, shaking his head, but James caught his chin and held his jaw tight. “Open your eyes when Barty’s talking to you, baby. Don’t you dare close them again,” he practically purred, groaning when Regulus’ bloodshot eyes opened and more tears spilled down his cheeks.

Something suspiciously close to a muffled “I can’t” sounded through the muzzle and Evan laughed from his spot beside them, languidly jerking himself off to the sight before him. “Does it look like we care if you think you can’t?” He said, a sharp smirk twisting through his lips.

Barty gave James a nod and pressed his hips forward, his moan drowned out by James groaning and Regulus making every noise he could through the muzzle. He shook like a leaf, gripping the bed sheets so hard his knuckles were bone white.

“So fucking tight, holy fuck,” Barty groaned, not even halfway into Regulus’ stretched cunt. He paused for a moment, and his hand darted out to pinch Regulus’ swollen clit. “Did we say you could close your eyes?” He growled.

Regulus scream-sobbed through the muzzle and drool dripped around the leather. James yanked on the leash and pressed his lips to Regulus’ ear. “Behave, pet, or we might stretch you out further so Evan can fit in your wrecked cunt, too.”

Regulus’ eyes went wide and his whines quieted marginally.

Evan laughed and crawled across the bed to Regulus’ head. “Can I use his mouth, James?” They’d already agreed on it, but James appreciated Evan asking. He grinned and Evan matched the expression.

“Here’s what’s going to happen, baby,” James whispered, “we’re going to take your muzzle off, and if you can stay completely silent while Barty stretches you the rest of the way, we’ll fill your mouth with something better, okay?”

It was cruel, really, James thought, asking such an impossible thing from a man so deep into subspace that he likely didn’t understand their words—though they’d talked their plans through extensively before the evening began, of course—but it was hot as fuck.

The muzzle came off easily, and the mouthpiece slid out of Regulus’ mouth coated in saliva. “Such a pretty little puppy, aren’t you?” James whispered, and Regulus shivered. “Are you ready?”

When Regulus stayed silent, James nodded and clenched his jaw as Barty’s cock bullied its way into Reggie’s impossibly tight hole. Regulus was a mess of snot and tears and sweat, and little whimpers slipped through his lips without pause. To his credit, he wasn’t screaming like before, so James’ words must’ve had some effect.

“That doesn’t sound like silence to me,” Evan said, but Regulus was too far gone to understand his error. James angled the younger man’s head towards Evan and he obediently opened his mouth, eyes open like he’d been told.

James knew first hand how good Regulus was with his tongue, especially with the damn tongue piercing he’d teased James with on more than one occasion. Evan nodded at Barty and slid into Regulus’ mouth as Barty drew his cock from Regulus’ cunt, ramming back inside when James pulled back so as to keep Regulus’ hole filled at all times. The drag of Barty’s dick and Regulus’ velvet walls was driving James insane and he knew he wouldn’t last.

He snaked a hand down to rub Regulus’ clit and the man moaned around Evan’s dick. “Cum for us, baby,” James ordered and Regulus’ body seized, his cunt tensing impossibly tighter. “What a good little pet you are,” he groaned.

Regulus was writhing in James’ arms, again crying and whimpering profusely, and god, he was so, so gone. “I’m not going to last,” James said, and Barty grunted in agreement.

The heat in James’ abdomen coiled tighter and tighter, and he picked up the speed of his fingers on Regulus’ clit until the younger man tensed again and James buried himself as deep as possible in Reggie’s cunt. His vision blacked out, splashing white as the coil shattered.

James came down from his high in time with Barty, who pulled out slowly, breathing heavily. Evan dislodged himself from where he’d been fucking Regulus’ throat and grinned.

“May I fill the whore’s messy hole?” He asked, and Regulus whined, long past being able to use coherent words.

“Good lord, James, are you even human?” Barty breathed, catching sight of James’ hard cock still buried inside Regulus’ ruined pussy.

James just winked and spread Reggie’s legs wider so Evan could push in beside him. Evan was bigger than Barty—not by much, but enough—and Regulus’ back arched obscenely as his body fought to accommodate the new intrusion.

His mouth hung open—perhaps he no longer had the wherewithal to close it?—and his moans were fucked-out and raspy, a pathetic echo of what they were when the evening began.

“He came twice, yeah?” Barty asked, and James nodded.

“Don’t let up until he’s had five,” James growled, determined to fuck Regulus unconscious, just like the younger man had whispered about weeks ago when they were trading fantasies.

What Regulus wanted, Regulus got.

 

With a thick plug between his legs and a vibrator on his massively-swollen clit, Regulus’ body finally went slack. James’ chest warmed with pride and he was sure Barty and Evan were similarly proud. They’d each cum several times, though none of them came close to the number of orgasms they’d managed to wring out of Regulus. The younger man would likely be sore for several days.

“I’ll go run a bath, yeah?” Evan whispered, eyeing the mess of a man sprawled unconscious on the bed. “Why don’t you go get some food and water for our doll, baby,” he said to Barty, who nodded and they both left the room. James was grateful for a moment alone with Regulus, even more so when the man began to stir.

Regulus groaned and his eyes cracked open.

“Welcome back, pretty boy,” James murmured, holding Regulus close. “You did so well, baby, so good. I’m so proud of you.”

Regulus was trembling again and James’ blood ran cold when he felt fresh tears on his skin where Reggie’s face was pressed to his chest.

“What’s wrong, darling?”

Regulus sniffled quietly and shook his head.

Sometimes, Regulus needed a moment or two before he could speak after particularly rough scenes, and despite his worry, James was content to wait as long as Regulus needed.

“I’ve got you, baby. I’m not going anywhere,” he said, running his fingers through the man’s sweaty hair.

Hurts,” Regulus whispered, whining softly from the back of his throat.

“Can you tell me what hurts, honey?”

Regulus shrugged and sniffled again. “Back.”

James knew little about Regulus’ many scars, but he was no stranger to the pain they sometimes caused the man, often after intense activity.

“I’m proud of you for telling me,” James praised, “how about we take a warm bath and get you some medicine?”

Regulus hummed, and James stood, carefully picking Regulus up so he wasn’t putting too much pressure on the man’s back. Evan wasn’t in the bathroom, but the bath was drawn and the perfect temperature, filled with green, sparkly bubbles, and James made a mental note to hug Evan for his attention to detail.

“‘M full,” Regulus muttered as James helped him into the bath and then climbed in behind him, situating the smaller man in between his legs.

James wrapped his arms around his boyfriend’s waist. “You’re very full, darling. Would you like me to clean you out?”

Regulus’ eyes were fixated on the base of the plug just barely visible through the bubbles. “How full?”

“More full than ever, doll. Can you see the bump?” He said, pressing gently on the distended portion of Regulus’ navel. Regulus whimpered softly and his hips twitched. “Does that feel good?”

Regulus nodded and his eyes slipped closed.

James loved moments like these: the calm, warm intimacy that came after harsh scenes, and if the scene had been a success, he usually helped Regulus have one last orgasm. He only used his fingers, he only used slow movements, and he only used praise. It was grounding for both of them, and the warmth of the bath and their closeness made it just as pleasurable for James as it was for Regulus.

“You were so good today, baby. You were so good,” he whispered, rubbing slow circles around the man’s clit with one hand while he massaged Regulus’ stomach with the other. “You listened so well.”

Regulus exhaled a shaky breath, more of a sigh than a moan, and James kissed down his jaw. “You’re perfect, baby. Everything about you is perfect.”

James pressed a soft kiss to Regulus’ lips.

“You took everything you were given like you were made to, baby. So, so good.”

Regulus came with a shudder and James talked him through it, removing his hands from between Regulus’ legs as soon as the man’s high dwindled.

“I’m going to get you nice and clean now, baby, okay?”

James started with Regulus’ hair, working shampoo and conditioned through the strands while massaging his neck, shoulders, and scalp. Usually, he’d clean the man’s hair last, but he didn’t want Regulus sitting in the bathwater after he took out the plug.

“You’re so pretty,” James said, carefully cleaning the conditioner from Regulus’ hair. He moved onto soap next, massaging Regulus’ arms and legs as he went. He avoided the man’s back, not knowing exactly where it hurt.

Regulus was pretty, no matter how you looked at him. He was pretty when he was onstage, singing his heart out, he was pretty when he was angry, he was pretty when he crying, he was pretty when sleeping, he was pretty when concentrating, when showering, when laughing—

James thought that maybe the prettiest version of Regulus was the one that he was holding, all waterlogged curls and peace so deep it eased the stubborn crease in his brow that even sleep sometimes couldn’t touch.

“I’m going to clean you out now, baby, okay? It’s going to be a bit uncomfortable but it’ll be over soon,” James murmured into Regulus’ neck and the man nodded.

He eased the plug out and with one hand, he pressed on the expanse just below Regulus’ belly button. Two fingers on his other hand slid as gently as possible into Regulus’ gaping hole to scoop out the cum fucked deep inside. The hand on Regulus’ stomach pressed a bit harder, but still not hard, and with his remaining strength, Regulus helped push the mess from his wrecked pussy.

“Almost done, baby, almost there,” he whispered, ghosting feather-light kisses up the man’s shoulder. “Just one more push, honey. One more and you’ll be clean.”

James lifted Regulus out of the tub and dried him with the fluffy towels reserved for times like these, and helped him into one of James’ sweatshirts. “Underwear?” James asked, knowing sometimes Regulus preferred to go without them when he was particularly sore.

Regulus shook his head and James led him back to the bed, where he found clean sheets where the drenched ones had been. There were two glasses of water on the nightstand, a bowl of assorted snacks, and a bottle of advil. Barty and Evan really knew how to win a man over, James thought, making sure Regulus had his entire glass of water, a small snack, and medicine before he laid down.

“I’ve got you, baby. You can sleep now,” James said, holding a still-trembling Regulus close to his body as the man’s eyes slipped closed.

 

Twenty minutes after Regulus fell asleep, the bedroom door creaked open and Evan poked his head in.

“James, are you awake?”

James waved him over and Barty followed suit. “Thank you both for everything. Seriously, you guys are incredibly thoughtful, and I hope you enjoyed yourselves as much as I did,” James whispered, hoping his words adequately conveyed his gratitude.

Evan smiled. “Of course, James. Barty and I still can’t believe you agreed to this, but it was so much fun. How is he?”

In James’ arms, Regulus’ even breathing tickled his neck. “His back was bothering him, but he’s good. It took him longer than usual to come back down, and I’m not sure he was all there, after the bath. It was like he was nearly grounded, just to slip away again.”

A concerned frown twisted Barty’s lips. “When we’ve sometimes gotten too rough, he’d dissociate towards the end or right after. It was a trauma response, y’know? But he’s been talking to someone about it.”

“We figured giving you two some time afterwards would help if he wasn’t back down to Earth when he woke up,” Evan added.

James considered Barty’s words, stowing them away for the morning. “I’ll talk to him about everything tomorrow, but I’m relatively certain this is something he’ll want to do again.”

Evan raised an eyebrow, “and you?”

God, it was so fucking hot,” James said, shaking his head minutely.

Barty muffled a laugh with the back of his hand and nodded. “Y’know, you’re not so bad, Potter,” he said, and James rolled his eyes. Barty had ‘jealous type’ written all over him, but James couldn’t bring himself to care, not when Regulus was in his bed and in his arms.

“You’re good for him,” Evan muttered, and there was a warning there, one James took to heart. He’d sooner cut off his own arm than let harm befall Regulus.




[Regulus POV]

 

Regulus wanted to take back everything he’d said about being sore when James fucked him, because those instances had nothing on the state he woke up in. He was warm, but that’s where the good things ended. He wasn’t even sure he could walk.

He could hear James in the kitchen, so he grabbed his phone from the bedside table and pressed James’ contact.

“Regulus? Are you okay?”

“I can’t walk,” Regulus groaned and good lord his voice was wrecked. “I think you nearly fucked my spine out my damn nose.”

James chuckled into the phone and Regulus heard the creak of the stairs, then footsteps outside the bedroom. “That sounds about right,” James said from the doorway, hanging up the phone call.

He handed Regulus a cup of coffee and climbed into the bed next to Reggie.

“How are you feeling, honestly?”

Regulus took a sip of coffee and set it on the bedside table, shifting so he could lay his head on James’ chest. “Do you know what happened to me in the house I grew up in?” He asked instead, struck with the sudden need to tell James everything.

James’ fingers found his hair. “No, not beyond what you’ve told me.” He didn’t mention all the scars he must’ve seen, and Regulus was grateful.

“When you’re a woman born into the Most Noble House of Black, you undergo ‘training’ as soon as you begin puberty. For generations, the men of the family have been arranged to marry women who reach ‘maturity’ at young ages, so as to allow ample time for the creation of an heir.”

Regulus wanted to cry, but he continued before he could lose his momentum. “The training was torture, and the stress of Sirius leaving must’ve really fucked me up because I reached ‘maturity’ at ten years old. My training began two days after my birthday.”

“Sirius doesn’t know about this, and I can’t tell him.” Regulus took a deep breath and focused on the warm hand in his hair. “Purity was of the utmost importance, and ‘purity’ was defined as a woman’s completion of her training by members of her father’s family. I was to be made pure by my father’s brothers and nephews and uncles and cousins.”

Regulus wanted to cry.

“I…endured it, all of it, for over half a decade, and think there are pieces of me that were taken in that house that I’ll never get back. I don’t know if I want them back,” Regulus whispered. He swallowed hard and wanted to cry.

“Last night was everything I wanted it to be.”

“But?”

“I don’t know what happened. I woke up and I was back there, and I knew it wasn’t real, I could hear your voice, but I couldn’t shake the fear that it wasn’t real. That…that if I pinched my arm I’d wake up in my childhood bedroom, chained to the headboard.”

James smoothed gentle circles over the skin of Regulus’ shoulder.

Regulus wanted to cry.

“It was so perfect up until the end, and then it wasn’t and I don’t know why and I couldn’t get it out of my head that it could be real, but I knew it wasn’t, I did—”

James sat up and pulled Regulus into a tight hug. “Reggie, baby, listen to me. I’m so, so sorry you had to go through that when you were younger. You deserve so much better than that.” He pressed a soft kiss onto the top of Regulus’ head and rocked them softly back and forth.

“I think some things take time, and I know that’s the worst answer, but hard scenes like last night’s are hard. And even if you really, really want to do it, sometimes you have to work up to it. Just because now isn’t the best time to do it, that doesn’t mean we can’t try again in the future.”

“But I don’t know what happened,” Regulus whispered, feeling paper thin and too vulnerable for his liking. “Did I do something wrong?”

“Of course not, baby, you were perfect,” James hummed, “we can talk about it, or you can talk to a professional about it, if you’d like. I had a lot of fun last night, but I don’t have fun when you don’t have fun.”

Regulus tried to make sense of James’ words. “I’ve been seeing this doctor to talk about everything,” he said, and he wanted to cry.

“I’m proud of you, I know that can’t be easy.”

Regulus wanted to cry.

“The meetings are online, because of the concerts. Sometimes Sirius is there, too.”

“That’s great, Reggie. I’m so proud of you, more than you know.”

Regulus wanted to cry.

“What if it happens again? What if we do a— a scene like last night and…. And what if I dissociate in the middle, not after the end?”

James held Regulus tighter. “Remember what we talked about? I’m always watching your body language, honey, and you can tap out at any time. I notice when you’re slipping, and if it happens in the middle of a scene, we’ll stop immediately—”

“But what about you—”

“Regulus, I can only get off if you’re enjoying yourself,” he said, still rocking them.

Regulus wanted to cry.

“I’m sorry,” he said, because he didn’t know how else he was supposed to respond to James’ unrelenting kindness. It still took him by surprise, even after weeks of intimately knowing the man.

James kissed the hollow beneath his ear. “You haven’t a thing to apologize for, darling,” he whispered, and Regulus wanted so badly to believe him.

“You deserve the world, Regulus.”
