"Je vais te ruiner mon amour." Regulus moans as you finally get his pants off. "LILY! LILY LOOK AWAY FROM THE SIN!" James screams as he picks her up and throws her over his shoulder and sprints for the door as Sirius does the same with Remus. Marlene and Dorcas are as red as Lily's hair as they follow behind and Narcissa brings up the back after figuring out what's going on. Lucius and Severus dawdle until Regulus grabs his wand and growls, "If you're there when I look up again, I'm not responsible for what happens to the two of you." You laugh breathlessly as you grind against his thigh while he leaves dark bruises on your neck and shoulder and when you finally pull apart to catch your breath for a moment, the room is entirely empty. "Je veux te faire jouir," Regulus moans as he flips the two of you as the chair beneath you quickly morphs to become a bed. 

The moan that he pulls from you with just this whispered phrase as he stands briefly to yank his shirt over his head before crawling back on top of you, is nothing short of absolutely filthy. "Love it when you moan like that for me, Minou." He whispers as he kisses you softly which does absolutely fuck all to stop the lust boiling your blood. "Reg...mmm...Regulus, you know...what happened last...time you got me...this worked up," you say in between kisses that are so hot you're surprised the room isn't engulfed in flames. A chuckle as dark as his surname is the only answer you get as he kisses from your lips down to the other side of your neck that he hadn't managed to leave marks on and you take it that, he's not concerned about you leaving his back in a bloody mess from where you'd dug your nails into it.

"Reg, I'm serious!" You gasp and he stops and leans up on one elbow to look down at you with his crystalline blue eyes full of mischief. "Well, fuck me. Never thought I'd be this turned on by my own brother," He teases which earns him a slap to the chest from you. "That's foul!" You growl and the look in his eyes changes from mischief to danger as his hand snakes it's way from where it was caressing your thigh to your throat. 

"Did you just growl at me, kitty? Hmm?" He whispers in that voice he used to in your first year at Hogwarts together. It's a tone laced with venom and hatred and something darker underneath. Something that had made you want him and hate him from the moment you had first spoken to each other. It was a sinful lust that the two of you had fought hard the first two years to not give in to. But then third year and puberty hit and it was like trying to fight fire with fire. You two had ended up shagging all over the castle and even in places that Sirius hadn't managed to find or get to which still had him pissed off at the two of you.

"I...yes." You moan unable to control your own body's reaction when he got rough with you. "You love it when I do this. And you're so beautiful when you let go." He whispers happily as he leans down and leaves a trail of kisses from your exposed neck to the top of your stomach before letting go of your throat. A soft, sad whine leaves your lips but is quickly silenced when you feel his teeth biting into the inside of your thighs. 

"Fuck Reg, stop teasing!" You beg but he's not showing any mercy tonight. He's about to bear his soul to you and whatever gods of lust and depravity dare look upon the two of you and the look in his eyes as he looks back up at you with your legs hooked over his shoulders reminds you of the old Dracula movies that you, Marlene, Dorcas, and Lily are obsessed with. You're quite sure if there was a way, Regulus would in fact eat you alive in this moment. "I'm about to show this whole gods damned castle who you belong to, Minou. And don't you dare try and be quiet. Do you understand?" He growls quietly and the only answer you could muster up before this dark god knelt before you was a nod.
