Work Text:
Regulus always had a tendency to go for the wrong people, he knew. He knew that his family must have screwed with him in the worst ways possible. He knew that he shouldn't really indulge the things they taught, he knew that even in a world as insane as the one he'd grown up in, it was still taboo for him to take the things he wanted. Especially when the thing he wanted the most was his own flesh and blood.
Regulus watched as his brother stumbled into his dorm, clearly frazzled and possibly intoxicated from the look of him. Sirius' curly hair was sticking to his face and neck with sweat, a wild look in his pale blue eyes and a rough pattern to his usually stable breathing. Regulus had never seen his brother so... off. Sirius was always more put together given his desire to keep his less than stellar reputation. Regulus couldn't help but stare at his older brother, confused by his disheveled appearance. It would be so easy to coax him into anything Regulus wanted, even without having to make him take a potion. He could make Sirius into nothing but a slave for him right now if he really wanted that.
But Regulus knew better, Sirius would never take advantage of him that way and he couldn’t do it. Sirius was his older brother who’d always taken care of him, maybe it was his turn this time, his urges aside.
"Sirius."Regulus whispered.
Sirius flicked his gaze toward Regulus but was otherwise unresponsive.
Okay, so he isn't drunk. Regulus supposed that was a good thing, his brother was never the type that could really handle liquor.
"Sirius."Regulus repeated. "What the hell happened?"
Sirius stopped in front of Regulus, gripping his shoulders like a vice as he finally made eye contact, the wild look in his eyes only seeming to deepen. Regulus wasn't sure how he was supposed to react, so he just stood there, stiffly while he waited for an answer.
"Had to find you."Sirius muttered. "Had a... Had a dream you... you..."
Sirius' voice trailed off and he looked away, grimacing at the floor and letting go of Regulus' shoulders.
"You had a nightmare."Regulus replied, gently pushing the hair out of Sirius' eyes with his fingers.
"Y-yeah."Sirius confessed.
"You don't have to tell me about it but, see? I'm okay."
Sirius sighed and his shoulders relaxed slightly as he slumped into his brother's chest a little.
Why couldn't he be less adorable like this. It was pure torture. He would never agree to anything even if the things Regulus wanted to do to help might calm him down. The pure fear and pity in Sirius’ eyes made Regulus wish he could just make it go away, just get on his knees and suck Sirius off until that fear went away.
"M'sorry I came down here so late... I'm sure you were-"Sirius rambled but Regulus cut him off with a gentle press of his thumb against Sirius' lips.
"I wasn't sleeping. I promise."
Regulus left his response at that, not particularly wanting to clue Sirius in on the reason. Sirius rested his head against Regulus' neck, making a slight shiver run down Regulus' spine.
"Do you want to stay in here tonight?"Regulus whispered.
"You could get in trouble for that."Sirius replied, wrapping his arms around Regulus protectively.
"If the staff has a problem with me helping my own brother, then they have worse issues to deal with themselves. Come on."
Regulus gently pulled Sirius toward his bed. Sirius followed, silently and allowed Regulus to lay him down on the mattress. Regulus sighed as he laid beside him.
"Why are you up so late anyway?"Sirius whispered, turning to rest his head on Regulus' chest.
Because I was imagining this being a late night fuck and not a therapy session. Regulus thought. "Just couldn't sleep, really. Been the case quite often, honestly."
Sirius sat up slightly to look down at Regulus.
Fuck. Sirius is gonna hate him. But he looks so damn good. Especially when he's exhausted and so, so vulnerable.
Regulus forced himself to press further into the mattress, trying to control his urges. Not that Sirius’ tired voice and caring eyes were any help.
Sirius seemed to notice, much to Regulus' dismay. "Restless, I assume? Worried about school or... friends?"
Regulus laughed, guess he wasn't going to leave this alone. Regulus should have at least known that much, Sirius was always the one to want to know everything. "Family, actually."
Sirius smiled a little at that. "Awe, was my little brother worried about me?"
"Never."
Regulus let himself have the small pleasure of resting his hands on Sirius' chest. Sirius glanced down at Regulus' hands before his gaze rested on Regulus' eyes. Regulus swallowed hard and quickly dropped his hands back at his sides.
Sirius arched an eyebrow. "What exactly about family were you thinking of?"
"You don't want to know."Regulus replied.
"Maybe if you told me I could... I could get it off your mind?"
Regulus couldn't help the breathy laugh that escaped his lips. "You don't know what you're asking, Sirius."
Sirius pouted slightly. "I want to help."
"You really wanna know how you can help?"Regulus asked.
"Mhm."
Regulus let out a sigh and ran his hand over his face before replying. "Honestly I was thinking about how badly I want to do some unbelievably un-brother-like things to you."
Sirius paused for a moment before breaking into a fit of giggles, turning over onto his back beside Regulus. Regulus sat up and scowled over his shoulder at his brother.
"Why is that funny?"Regulus asked, a little annoyed.
Sirius let out a breath, finally done giggling. "Regulus, honestly. I figured as much."
Regulus only sat there for a moment.
He knew? How the hell did he know?
"You knew?"Regulus rasped.
"We're already inbred. It's basically in our genetics to want to fuck the shit out of each other."Sirius explained. "So I am really not that surprised that you've been thinking about it. The idea has passed through my head here and there."
"You could have acted on it."
Sirius shook his head, still grinning. Regulus rolled his eyes and straddled Sirius' hips.
"I'm literally telling you, you can take what you've thought about."Regulus said.
"You couldn't handle it."Sirius replied.
"So you're saying even if I were to offer myself to you, right now, you wouldn't just take it?"
Sirius shook his head. "Wouldn’t want to scar you that way, Reg."
"I want you to."
Regulus took Sirius' hands in his, guiding them under the hem of his shirt. Sirius' breath came out shaky as he slid his hands further up, lightly grazing Regulus' nipples with the tips of his fingertips.
"This is a bad idea."Sirius muttered as he began to gently pinch each nipple between his thumbs and forefingers.
Regulus let out a soft gasp. "Said the king of bad decisions."
"Reg, we really shouldn't. Your roommates are sleeping not even ten feet away."
"They both sleep like the dead. Just don't stop."
Sirius pulled his hands away, making Regulus' body feel cold. Regulus went to grab Sirius' wrists but Sirius pulled away.
"We can't."Sirius said.
"Please, Sirius. I need this."Regulus whispered, leaning down to press pleading kisses to Sirius' jaw.
"Reg..."
"Siri, please. Just... just one time. It doesn't have to happen again."
Sirius tilted his head back, allowing Regulus better access which Regulus happily took, kissing Sirius' neck and gently nibbling, just wanting to taste the sweat on his skin.
"Please. Please."Regulus whispered.
"Maybe a little."Sirius muttered.
Regulus sighed against Sirius' neck and continued kissing, savoring the taste of something that is likely to not be offered again. The sounds of Sirius' heavy breathing making the waistband of Regulus' pajama bottoms tighten.
"Touch me. Please. Anywhere."Regulus whispered in his older brother's ear.
"Where do you need it?"Sirius replied.
"All over. Your hands are so warm... they feel good."
"Show me, baby brother."
Regulus did exactly that, taking Sirius’ hands and pressing them against his hips.
“Take me… please.”Regulus whispered.
Sirius hummed, sliding his hands back and gripping Regulus’ plump ass in his hands, making Regulus gasp. “I kind of enjoy it when you're begging, Reggie.”
Regulus began to rock his hips back and forth, grinding against Sirius’ hips, earning a groan from the older one beneath him. “You won't hear it again.”
“Mhm…”Sirius muttered in a daze, his breathing heavy and shallow. “Just don't stop.”
Regulus started to move his hips a little faster against Sirius’, quiet moans deep in his throat. Sirius tightened his grip on Regulus' rear and started to move his own hips at the same pace.
“Merlin’s sake, Reg. Who knew you could make me so damn horny…”Sirius muttered under his breath.
“More.”Regulus whispered in Sirius’ ear.
The friction felt good but there was still too much in the way for Regulus' liking. He wanted to feel every inch of his brother's body against his, wanted to practically crack Sirius' ribs open and live inside him forever.
“Then take it.”Sirius replied, bringing one hand up to pull at Regulus’ shirt.
Regulus needed no further instruction and made quick work of practically ripping both of their clothes off, stripping them both down to nearly nothing. Sirius, of course, opted not to wear anything under his usual old sweatpants. Regulus, still in his boxers, nearly drooled at the sight of his brother's erection, the length of it pressed against Sirius' stomach.
Merlin, Sirius was huge. Regulus’ cock twitched in his underwear just imagining what it would feel like.
Regulus’ mind was torn between two things.
One; he wanted Sirius to fuck him mindless right here, right now.
And two; He wanted to fuck Sirius so well that maybe he'd forget at least for a moment how wrong what they were doing was and just want Regulus as he was, family or not.
The only problem? Of course it was in this moment that he realized, he's really never done this before. He'd been running purely off of what he wanted to do. But his lack of experience seemed to catch up all at once as he saw his brother's flushed face looking up at him.
“I've never… I've…”Regulus stammered.
“Felt like you knew.”
“I don't know what I'm doing. I don't even know what would feel good.”
Sirius chuckled softly. “I couldn't tell you, honestly. Never really been in charge before.”
Regulus smirked. Oh, so Sirius wasn't as dominant as he thought. Obviously, Regulus found no problem with that.
“What?”Sirius asked, blushing a little darker.
“So you're usually the one being told what to do?”
“Yeah. Is that an issue?”
Regulus laughed softly and shook his head. “Fuck no. Just… unexpected. But you seem reactive so maybe I could just experiment a little and find out what you like. Since you don't know how to tell me.”
“Do your worst, then.”
Regulus smirked, widely and leaned down, pressing a feather light kiss to the tip of Sirius’ cock. Sirius bit his lip and threaded his fingers through Regulus’ hair.
“S-silencing charm. I'm not exactly… quiet.”Sirius mumbled.
“There’s always one set on here. Barty and Evan are loud as hell too.”
With a gentle, desperate nod from Sirius, Regulus took the tip of his brother's erection into his mouth, listening to Sirius’ moans as he began to bob his head.
“Faster, Reg. Please.”Sirius said with a low groan.
Regulus happily picked up his pace, taking as much of the length as he could down his throat, ignoring the feeling of the tip hitting the back of his throat. Sirius moaned and arched his neck, Regulus simply watched through his eyelashes as his brother's chest rose and fell with each heavy breath.
“Fuck, Reg, Reg.”Sirius chanted, gently bucking his hips.
Regulus sucked slightly harder, wanting to feel it when Sirius finished. This only made his brother cry out his name louder and blush, covering his mouth with his hand. Regulus slowed to a stop and pulled away, gripping Sirius’ cock in his hand. Sirius looked up at him with wide eyes.
“You’re allowed to call out my name.”Regulus said. “Especially when I'm the one who's making you come.”
“You're my brother.”Sirius replied, letting his hands fall to his sides.
“Does what I'm doing feel good?”
“That's not the-”
Regulus smacked Sirius' thigh, eliciting a gasp from the older boy. “Answer the question.”
“It feels incredible.”Sirius replied, biting his lip softly. “But you're my brother and I definitely should have left.”
“Do you still want to leave? ‘Cause if you do, there's the door.”
Sirius only stared up at him, not moving. Regulus smirked.
“Thought so.”Regulus said, slowly moving his hand over Sirius’ cock. “Now, if you cover your mouth again or quiet yourself at all, I do have toys in my dresser and believe me, everyone will know who exactly made sure you can't walk tomorrow.”
“Reggie, you couldn't. I…”
“Oh I couldn't? Are you willing to bet your reputation on that, big brother?”
“Reg-”Sirius started.
“Answer the question.”
“I mean… I'm curious what you mean by that threat. But I don't think you could do enough to break me like you say you can.”
Regulus leaned his head back and laughed, it went from a dry laugh to nearly hysterical. He knew he sounded insane like this, but he didn't care. His brother still saw him as his baby brother, even now. Even when only a few minutes ago, Regulus was choking on Sirius’ cock.
“What's so funny?”Sirius asked, sounding a little offended.
Regulus took a breath to calm his giggling and looked down at his brother. “You still see me as your kid brother. You think I'm too young, too small, too helpless. And I think that's hilarious. Especially in our current situation.”
“I don't think there's anything you can do that would change how I think about you.”
“Even now?”
“Even now.”
Regulus shook his head and got up. Sirius raised an eyebrow at him, sitting up and propping himself up with his hands behind him.
“You think I can't do anything? At least… not enough to break you? I'm not exactly innocent despite the virginity part.”Regulus asked.
“What are you planning to do then?”Sirius cocked an eyebrow at him.
“Break that stellar reputation of yours. The one that made you a prankster with incredible grades and a rare talent for magic, the one that separates you from our family and from me.”Regulus explained, opening his top dresser drawer. “I tried not to be petty about this but unfortunately you constantly wake that up in me. So I’m going to make sure your friends know that your family values are still there.”
Sirius got up from the bed.Regulus’ bed and walked over to him. Regulus could feel his brother's warm arms wrapping around his waist, his bare chest pressed against Regulus’ back.
“You think my reputation is more important than you are to me?”Sirius whispered in Regulus’ ear.
“It seems like it.”Regulus muttered.
Sirius leaned down, pressing his lips to Regulus’ jaw. “No, Reggie. Just because I don’t care about our family's values or what they think of me, doesn't mean my own brother comes second to anything.”
Regulus let his eyes flutter shut and tilted his head, not wanting Sirius to stop. “You tried to leave earlier. Said we shouldn't be doing this. What changed your mind?”
“I don't want to leave.”he whispered. “I just know that I shouldn't be doing this with you. No matter how good it feels.”
“Does it feel better with someone else?”
Sirius gently nipped at Regulus’ ear. “Don’t make me answer that.”
“I wanna know.”
Sirius sighed and pressed his forehead to the back of Regulus’ neck. “No. Actually, you are far better. But that doesn't make this a good idea.”
Regulus turned around to face Sirius and cupped his brother's face in his hands, fingers brushing along Sirius’ cheeks. Sirius leaned into the touch and looked down at him.
“Are you wanting to stop?”Regulus asked.
“No.”Sirius replied.
“Then please. Just touch me again.”
Sirius knelt down in front of him, pulling at his waistband and looking up at him.
“Come on.”Regulus whispered. “I want to watch you choke on it.”
Sirius nodded and pushed Regulus’ boxers to the floor, wasting no time with taking Regulus’ hard cock into his mouth and pressing his tongue against the tip. Regulus let out a soft moan.
“More. I know you can take it.”Regulus whispered.
Sirius only bobbed his head slowly, making Regulus buck his hips a little.
“Faster or I'll just have to use you.”Regulus said.
Sirius didn't pick up his pace, but took more down his throat still. Regulus groaned, low in his throat and gripped Sirius’ long curls in his hand, bucking his hips and shoving his cock all the way in to the hilt. Sirius moaned around his length and allowed it, his eyes shut tight.
“Look at me. I want you to watch when I come down your throat.”Regulus ordered.
Sirius gripped Regulus’ hips as Regulus fucked his mouth harder. Sirius moaned in time with each thrust, the sound reverberating against Regulus’ length.
“Such a good boy. You were so shy and now look at you. Enjoying your brother's cock like that.”Regulus praised as he slowed to a stop, watching Sirius’ face turn red.
Sirius looked up at him with a pleading glint in his eyes. Regulus smirked and pulled his cock nearly all the way out of Sirius’ mouth.
“Awe, does my big brother want me to come on his face then?”Regulus teased.
Sirius nodded, almost desperately. Regulus pulled out and rubbed the precum from the tip on Sirius’ lips before turning around and shoving Sirius’ face right into his ass. His body felt even warmer as Sirius’ tongue started to explore Regulus’ tight hole.
“Fuck yes. Be a good little slut for me and make sure I'm nice and stretched out for your big cock, Siri.”Regulus muttered.
“Yes sir. Anything for you.”Sirius replied before pressing his tongue inside.
Regulus felt his eyes roll back and his knees start to shake. Sirius helped him lower to his knees and Regulus bent over, arching his ass toward Sirius’ face. Sirius pushed Regulus’ cheeks apart and buried his tongue inside him. Regulus couldn't stop himself from letting out desperate and loud moans at the feeling.
“God, I need you inside me.”Regulus muttered.
“Wanna make you come first.”Sirius replied, lapping at Regulus’ hole with more fervor.
“Fuck~ Siri~”Regulus moaned out, feeling his erection ache with the need for release.
Regulus gently squeezed the base of his cock to ease the rush of sensations, trying hard to keep his word about letting himself finish on his brother's face. But, that was a much harder deal to keep when Sirius was just so damn talented.
“Holy shit… you're so good with your tongue, Siri.”Regulus praised.
“Still gonna come on my face, little brother?”Sirius teased. “Or is this too much?”
“You're such a prick.”Regulus scoffed, only for Sirius to draw out a much louder moan from him by sliding a finger inside him, curling it to hit the spot that makes Regulus scream.
“Please?”Sirius asked, slowly moving his finger in and out.
“Oh fuck.”Regulus moaned, feeling his legs start to shake more. “Come here.”
Sirius pulled his hand away slowly and Regulus turned around, legs quivering as he started to move his hand over his cock, cum squirting out almost immediately over Sirius’ face. Sirius looks up at him with a wide smirk.
“Awe, not so shy now?”Regulus teased, leaning back against his dresser to catch his breath.
“You’re already promising a lot, I don't see why I shouldn't at least let myself participate a little.”Sirius said, wiping the sticky substance from his cheeks and licking it off of his thumb.
“Shut up and lay down.”Regulus rolled his eyes.
Sirius winked and got up from the floor, sitting on the end of the bed. Regulus quirked an eyebrow at him.
“You said you wanted my cock? You’re gonna take it this way or not at all.”Sirius challenged.
“You’re really willing to be sassy about this? With your face still covered in my cum? You really are an arrogant bastard.”
“Just come here and take what you want already. I already know you want my cum dripping down your legs the rest of the night.”
“How could you possibly know that?”
“Because. Even though I’m not exactly the one in charge ever when I’m in bed with someone, you’re still my younger brother and you still think of me as the older, stronger one. So you want me to take you over and over again, any way I want to, you want me to make you thoroughly brainless because you’ve taught yourself that the only dynamic between the two of us is that I’ll protect you and do anything for you.”
Regulus blushed profusely as Sirius continued to speak, which only served to make his brother’s arrogance so much worse. Regulus was left almost entirely breathless, cheeks flushed and his thighs pressed together, head spinning with just the thought of what Sirius might do next.
“Oh? Have I said something wrong, little brother?”Sirius cooed.
“N-no.”Regulus stuttered in response. “How do you know any of that? Is it that obvious?”
“Everything about you has always been obvious to me. Now get your ass over here and let me take care of you the way you want me to.”
Regulus shuffled over to Sirius and straddled his hips. Sirius smirked and pressed the tips of his middle and ring finger to Regulus’ lips. Regulus settled on Sirius’ thighs, Sirius’ fully hard cock resting against his, as Regulus took his brother’s fingers into his mouth. Sirius hummed softly in approval.
“That’s a good boy. Have to make sure your little hole is ready for me before I split you open.”Sirius whispered in Regulus’ ear.
Regulus whimpered around Sirius’ fingers, gently rocking his hips forward to get a little more friction.
“Awe, just that desperate to come on me again?”Sirius teased before pulling his fingers out of Regulus’ mouth.
“Please… Siri…”
“Bend over my lap. I wanna stretch you out properly.”
Regulus gets up and bends over Sirius’ lap, ass in the air like he was unashamed of what they were doing. Sirius was gentle about pushing both fingers in, making Regulus gasp and arch his hips back for more.
“Have you ever fucked yourself, Reggie?”Sirius asked, the same sweet tone in his voice that he used when they were kids. “Ever made yourself come?”
“Y-yes. That’s why I have toys. Sometimes I need a break and just lay down and close the curtains around my bed so I can-”Sirius pushed another finger inside his hole, making Regulus whimper.
“Yeah? What do you think about when you’re using yourself like that?”
“Y-you. I think about the things you could do to me.”
“Good. Because I wanna make sure I’m all you ever think about. I want to make sure I fuck you so well that I’m the only one you’ll ever get off for. Even when you’re touching yourself, you won’t be able to finish because I’m not there to make you or talk you through it.”
“Please Siri.”
“Yeah? Is that an agreement then? You wanna be my toy?”
“Yes sir.”
“Good boy.”
Sirius pulled his hand away and helped Regulus sit up, positioning him toward the mirror and helping him slide onto his cock. Regulus whined softly at the feeling of being stretched and scratched at Sirius’ thighs as he tried to lean his head back, avoiding watching himself in the mirror.
“No, no, little brother. I want you to watch while you ride me. I want you to see the tears stream down your little red cheeks from feeling your brother’s big fucking cock in your ass. I want you to see it.”Sirius whispered in Regulus’ ear as he gently thrust his hips a few times.
“Can’t take it. Please Siri… Be gentle.”
“No. You liked fucking my face nice and rough, I’m going to return the fucking favor and fuck your sweet little ass raw, right now. And maybe if you’re lucky, I’ll give you a little show while you recover and use your little toys.”
“Yes please. Please. I’ll be good.”
“That’s what I thought. Now, eyes on the looking glass and let’s see you fuck your pretty ass on my cock.”
Regulus whined softly as he started to bounce on his brother’s throbbing erection, nearly feeling the length of it in his stomach as the tip hit just the right spot each time. He did his best, keeping his eyes on the mirror as he rode his brother. Sirius rested his head on Regulus’ shoulder, spreading his thighs apart with one hand and tweaking Regulus’ nipple with the other. Regulus; mouth fell open in a loud moan, picking up his pace and taking as much of his brother’s length in as he could.
“You’re such a good fuck, Reggie.”Sirius praised in his ear. “Especially for a little virgin like you. Such a natural talent.”
“Just for you, Siri. Fuck. M’so full.”
“I know, baby. You’re doing so well.”
“Come in me? Fill me up?”Regulus begged.
Sirius chuckled softly, teasingly and kissed Regulus’ neck, thrusting his hips harder. Regulus’ thighs twitched and quivered, feeling it when Sirius finally released his load deep inside him. Sirius took a few heavy breaths and helped Regulus up, laying him on the bed next to him.
“Awe, done already?”Regulus teased, ignoring the cloud of lust in his head that threatens to lull him to sleep.
“I did make a promise, yeah?”Sirius replied, getting up slowly and opening the drawer that Regulus was looking in earlier.
“Don’t-”
“Oh? These are bigger than I expected, Reg. One of your muggle friends help you find these?”
“Andromeda did. I was surprised she was so calm about it.”
“Well thank the stars for her then. I’d love to watch you fuck yourself stupid on one of these.”
“You first.”
Sirius smirked and took out a long black one, it was thick and one of the more realistic ones Regulus owned. Regulus bit his lip and squirmed a little.
“Is this your favorite one, Reg?”Sirius teased, turning around, toy in hand.
Regulus nodded shyly. “But I don’t think you wanna start there…”
“I’m not exactly a beginner, little brother. But.”Sirius straddled Regulus’ thighs. “I will need a little lubricant if you don’t mind.”
“You could just use a spell.”Regulus blushed.
“I’d rather watch you suck this before I ruin myself with it.”
Regulus sat up a little and Sirius held the toy up to the younger boy’s lips. Regulus started to open his mouth but Sirius pulled the toy away a little.
“Nope, do it nice and slow, like it’s a real cock.”Sirius said.
“It’s rubber.”
“You said you wanted me to use it. So you’re gonna do it right.”
Regulus glared at his brother for a moment before kissing a trail up the length of the toy and swirling his tongue around the tip.
“Good. Now let me show you how to really make it feel good when you fuck someone’s throat.”Sirius said, threading his fingers through Regulus’ sweat soaked hair.
Regulus let his tongue lay flat over his bottom lip as Sirius slowly pushed the toy in to the hilt. Regulus’ eyes rolled back as he felt the ridges and veins of the silicone rub against his tongue.
“Good boy. Now close your mouth around it for me and just relax. Maybe later I’ll let you try it on a real cock.”Sirius commanded.
Regulus did exactly as he was told and Sirius started to slowly thrust the toy in and out of Regulus’ mouth. Regulus moaned each time it went in, loving this far more than he expected to. He felt Sirius’ fingers gripping his hair before Sirius started to pick up the pace of his movements, nearly bruising Regulus’ throat with the force, but Regulus didn’t care, moaning as his brother abused his throat.
“Such a good fucking boy.”Sirius praised. “Can’t wait to see you sucking my cock like this.”
Regulus drooled a little, knowing he was getting sloppy and messy, but Sirius didn’t seem to mind, he slowly pulled the toy out and Regulus looked up at him. Sirius wrapped his hand around his throat and pressed his lips to his little brother’s, pressing his tongue inside and exploring for only a moment before pulling away.
“And I really thought it’d be you ruining me after you took charge earlier. But I like when you get messy like that. It’s such a change from how proper you usually are.”Sirius said, sitting up.
“Yeah… apparently I like it a little rough.”
“It’s really just a family trait. Now how do you want me? Gotta make sure you have a nice view.”
“Face down ass up in front of me so I can watch in the mirror.”
“Anything for you, little brother.”
Sirius did exactly that, bending over with his cheek pressed against the sheets as he started to push the tip inside himself. The sight was better than anything Regulus had ever seen, his brother’s mouth open in a perfect ‘oh’ as he fucked himself with just the tip alone.
“It’s so thick, Reggie.”Sirius whimpered.
“You can take it, big brother. I wanna see your ass fucking gaping when you’re done.”
Regulus sat up and spit on the toy and guided Sirius’ hand to push it in a little further. Sirius cried out and spread his legs a little more.
“Good boy. Fuck, you’ve got me so hard.”Regulus praised.
“Just for you. Oh fuck, how do you take this much, Reggie?”
“Because I needed some relief from wanting your cock so badly. Which is why I know you can take more. So come on, stretch your tight little hole out.”
Sirius moaned and shoved another inch in, crying out as it stretched him further. Regulus relished in the sound of his brother being so pathetic all for him.
“I know I said this doesn’t have to happen again but fuck, I could fuck you all day long. Just watching you ruin yourself all for me.”Regulus praised.
Sirius pushed a little more of the toy in, barely in halfway but he’s already sweating from the effort of taking it all. Regulus leaned down and gripped Sirius’ hair, bringing his lips to his older brother’s ear.
“Take it all or I will shove that pretty toy inside you hard. Make sure you’re shaking and drooling for me. I know you can take plenty of fucking cock, so you’re going to.”Regulus commanded.
“Please sir. Can’t take it.”Sirius whimpered.
“You’re going to take it. Even if it rips your pretty hole apart, you’re going to take it and when you’re done, you’re gonna let me test out a few of my new toys on you.”
“H-help? Fuck me?”
Regulus gripped the end of the toy and pushed it in to the hilt. Sirius let out a scream that would have alerted any staff member or student nearby if it wasn’t for the silencing charm. Regulus smirked and smacked Sirius on the ass, hard.
“Good boy. See? I told you you could take it all.”Regulus whispered.
“T-too much.”Sirius muttered.
“It’s not too much, baby. It fits perfectly.”
Sirius reached his hand back and started to finally thrust the toy in and out of himself, crying out so loudly he’s nearly screaming with pleasure each time. Regulus watches as Sirius’ cock drips with cum, not quite close enough to explode completely but red like he’s just on the edge.
“Awe, is my big tough brother already close from just a few little thrusts?”Regulus teased, gently tugging on his own cock to give himself a little friction.
“Y-yes, Reggie. I’m so close…”Sirius moaned, his voice breaking and cracking.
“Then come all over my sheets. Come on.”
Sirius rutted against the sheets as he kept thrusting the toy in and out. Regulus moaned, just watching his brother through the mirror at the end of his bed and touching himself to the sight.
“Reggie.”Sirius whimpered. “More. Please.”
“How so, big brother?”Regulus asked.
“F-friction.”
Regulus smirked. “Ever tried a toy on your cock before?”
“N-no.”
“Then let me show you how good that can feel.”
Regulus got up and opened the drawer to his small nightstand by his bed, taking a small cock ring out. Sirius’ eyes went slightly wide as he followed Regulus’ movements with his eyes. Regulus leaned down and opened the ring, tucking it under Sirius’ balls and turning it on. Sirius let out a choked moan and drool slowly rolled down his chin as he succumbed to an orgasm, cum squirting out in ropes onto Regulus’ sheets. Sirius body went limp onto the mattress as he caught his breath. Regulus slowly pulled the toy out and set it aside.
“You did so well, Siri.”Regulus praised, kissing a trail down Sirius’ spine.
Sirius hummed softly and turned over onto his back, the vibrator still running at the same high speed as Regulus left it at.
“Awe, do you want the toy off, pretty boy?”Regulus asked, kissing Sirius’ forehead.
Sirius nodded, gasping for air slightly. Regulus leaned down and licked the tip of Sirius’ cock, earning a soft whine from the older boy.
“Can I taste you a little more first? I just wanna know what you taste like after you’ve been fucked this thoroughly.”Regulus asked, looking up at Sirius with as innocent of a look as he could muster.
Sirius looked down at him with his eyes lidded over. “A-anything f-for you.”
“Awe, so I could just use you all up and you wouldn’t stop me?”Regulus teased.
Sirius nodded, mouth hanging open. Regulus leaned down and took the tip of Sirius’ half-hard cock into his mouth, feeling it harden again against his tongue. Sirius moaned and lightly bucked his hips, seemingly overstimulated. Regulus held his brother’s hips down as he went down on him, bobbing his head slowly to savor the taste.
“R-reg… Gonna come…”Sirius whined.
Regulus bobbed his head faster and let himself gag a little, loving the feeling of Sirius’ cock down his throat. Sirius cried out as he came a little more, his head thrown back in deep ecstasy before his body fell limp on the bed once more. Regulus pulled away and swallowed every drop, smirking triumphantly.
“So, still sure this was a one time thing?”Regulus asked.
“Definitely not just a one time thing. Fuck…”Sirius mumbled, his eyes seeming to struggle to stay open.
Regulus took the ring off of Sirius’ cock and used a simple cleaning spell to clean up the mess the two of them had made before laying down beside his brother and resting his head on his chest. The two of them quickly fell asleep without either of them having a care in the world what would happen when they woke up the next morning.
