"Yes, right there Siri!" Regulus screamed when his brother slid inside him in one sharp push, the pain of the stretch perfectly mixing with pleasure running through his body.
They were in the bathroom, just a hallway away from the family gathering happening in their drawing room, from where they slipped away fifteen minutes ago, because they couldn't keep their hands away from one another anymore.
It was a running theme, sneaking away from parties and dinners to feel each other up in secluded corners. It started a few years ago, when they discovered what kissing was and how good it felt when they did it, and it continued, they just added a few more things to it to make it even better.
Of course, they didn't only do it at gatherings, they sneaked around their house whenever they had time, fooling around at night in Sirius' or Regulus' bedroom, dragging each other in empty rooms just to feel their lips touching, sometimes doing it on the staircase or in the hallway, the thrill of the possibility of getting caught making them even more delirious with desire.
They weren't subtle, far from it in fact, but if there was one thing their family was good for, was this. They never mentioned it, had been ignoring it from the start. Every time Sirius corrected his collar or his tie, so that it wasn't crooked, after they mysteriously disappeared for half an hour, every brush of a hand a bit too low on his back or a kiss a bit too close to his lips was never mentioned, never looked at too closely. Every time one of them came back from their messing around with a bruise high up his neck, because they didn't bother with covering it up, eyes drifted past it as if it wasn't there.
It's an open secret in their family, one that was kept inside the halls of their family estates. Not because Regulus and Sirius were ashamed of it, not at all, if they could have, they would have made it as public as they could, but because of the hassle it would have caused if it had come out. Because after all, they were brothers. And for now, their parents turn a blind eye to it, because they weren't ruining anyone's reputation, were they. If anything, they were doing exactly what they were taught. Keeping their lineage pure. Toujours pur like his parents had been drilling into his head from the moment he was born.
Not that they would have stopped if someone had said anything. They needed each other, the touching and kissing and fucking bringing them close, satiating the want simmering in their blood and showing the love they had for each other. Because they did love each other, so much even the idea of being separated made them cling to one another as hard as they could. They left bruises, marks on each other's bodies, claiming the other, showing just how much they belonged to each other.
It was perfect, everything Regulus could ever had hoped for, and he could never get enough. No wonder that they ended up here once again, with Regulus bent over the sink, the cold marble biting into his hips a complete contrast to the heat of Sirius at his back, who pushed him harder and harder against it with every punishing thrust, most definitely leaving bruises.
His hand was fisting Regulus' hair, pain shooting sparks through his scalp that ran straight to his abdomen. He was making Regulus watch himself being thoroughly ruined, tears running down his cheeks and filthy moans leaving his open mouth with every single brush against his prostate.
He was loud, no inhibition left in him to try to muffle his sounds, not that Sirius would let him. He loved making him scream, his name tumbling out of his mouth as he came, loud enough for the neighbours to hear if they hadn't used a silencing charm.
Which he didn't know if they did this time, his mind too dazed from arousal to focus on such things, and the idea of everyone in the drawing room hearing what Sirius was doing to him made his eyes roll to the back of his head and such a deep moan was ripped from his chest Sirius bit his neck hard, muffling his own sounds of pleasure.
"Yes, that's it, baby. Scream for me, let everyone hear you, show them how good I make you feel." Sirius said into his skin and finally releasing his hold on Regulus' hair to run his hands down his sides, gripping his hips to push Regulus back against him in time with his thrusts.
His eyes stayed on the image in the mirror even without Sirius' grip, because the view was breathtaking.
He was a mess, spit and tears running down his face, cheeks and chest red from the arousal, and a big mark on his neck with a few drops of blood running towards his chest where Sirius' teeth pierced his skin. But Sirius, he was the one that made the picture so perfect. With his face tucked into his brother's neck, tongue running over his bitemark, his hair falling over his face, his hands, oh how he loved those hands, gripping his hips so hard the veins were visible, and it made Regulus salivate. To see the pleasure etched on his face, the darkness of his eyes when they met his own in the mirror. He was perfection, crafted from the gods, and the only things Regulus could do was stare into the mirror, drinking his fill of his brother fucking into him.
He was close, dangerously so, a few more thrusts and he would be gone. And then Sirius' hand slipped from his hip to the front, taking Regulus into his hand, and he was coming.
Eyes rolling back, his hands crumbling under the weight of his orgasm, making him drop on the sink, and a scream tearing from his mouth. The pleasure was other-worldly, almost too much to bear, but Regulus let it take over his body, swallowing him and making him see stars. He blacked out for a second, and when he came back, he felt his brother emptying inside of him, a groan spelled into his skin.
He shivered, the oversensitive rim making him hyper aware of every single movement Sirius made when he started pulling out slowly.
He looked back to their reflections, seeing his brother focused on his hole, where he could feel the cum leaking out. But before it could all run out, there was a finger pushing it back inside and a spell whispered under Sirius' breath, and when he pulled it out, cum stayed inside.
When Regulus realized what had happened, he let out another groan, his cock twitching even though he just came, because the knowledge he was going to walk around and talk with their family while having his brother's cum inside of him made him hot all over again.
"I know how much you love walking around with a reminder of what happened inside of you. Thought I would give a treat for taking me so well." Sirius pulled him up and turned him around when he said it, the smirk making Regulus surge up and kiss him, thanking him for it.
"Thank you," he whispered against his lips and then let his brother close up the buttons on his shirt, righting his clothes while he did the same to him, albeit not as efficiently due to his hands still shaking a bit after the mind-blowing orgasm he just had.
They left the bathroom as if nothing had happened, clothes fixed, and cheeks void of the flush. The only thing that hinted to what actually went down in there, was the bitemark on Regulus' neck, big and red and extremely noticeable.
Sirius looked at it with a possessive glint in his eyes, fingers coming up to touch it, pressing them into his visible claim on his brother. It made Regulus hiss, the bruise sore and painful at the touch, but it only made Sirius grin harder, a mean smile that promised danger.
He pulled him into one last bruising kiss, tongue slipping into his mouth for another taste, while his hand stayed on Regulus' neck, splaying over the bruise and pushing on it, swallowing the whimper Regulus released with the pain blooming in his neck.
He loved this, the possessiveness, the claim, the pain, because it was all made with love and desire. It showed him how much Sirius wanted him, craved him, and Regulus was hooked on it, always wanting more of it.
After thoroughly exploring his mouth again, Sirius pulled away and they finally joined their family again, after too long for nobody to notice.
Heads turned towards them, eyes snapping to the mark on Regulus' neck, but just like every other time, they snapped back to his face or to his brother, and then left them completely to continue the conversations they were having before their entrance.
No one batted an eye when Sirius, loud as ever, joined the conversation their cousins were having, and wrapped an arm around Regulus' waist to pull him in their direction, low enough to graze the top of his ass cheeks, reminding him he was still full of his brother’s spent.
Later, again, no one paid any attention when Sirius laid his arm on the back of Regulus' chair, his fingers lightly running up and down his neck, touching the bruise every now and then.
Some eyes lingered on them that time, the show of ownership clear as day, but no one said anything, their faces blank canvases that didn't show what they thought about it.
It set Regulus on fire, the publicity of it. Sirius didn't try to hide, but he flaunted it to everyone in the room. He could barely think with his blood rushing to his abdomen, pulse loud in his ears while his breathing got faster and deeper. The bruise on his neck and the full stomach were distracting reminders of what had happened not that long ago, and the promise of more was making him impatient, ready to bolt out of the room, propriety be damned, just so he could feel his brother again.
With the heated glances Sirius was sending him, his eyes raking up and down his body, Regulus knew his brother was feeling the same.
It was only a matter of time before they would excuse themselves again, this time for good, and secluding themselves in one of their bedrooms. This time they would take their time, picking each other apart piece by piece and then building the other up again and again, until they were spent and satisfied.
Then, they would hold each other close and let the tiredness take over them, falling into deep sleep until they woke and repeated the things from the night before once more with the sun shining through the window, no more shadows to hide behind and loving each other in the bright open.
