The nod is all it took and with a flash of a dirty grin that would rival his own brother's he disappeared between your thighs. You were about to lean up on your elbows to see what he was doing, but suddenly you felt his mouth on your soaking wet pussy. "Oh my...fuuuuck Reg!" You half gasp and half whine as you grab and handful of his hair then begin to grind against his mouth. What you didn't see earlier was him casting a silencing charm on the door of the Room of Requirement nor did you see him dispel the charm as you begin to get louder. "Do it again, mon amour. Let them hear what I'm doing to you," He practically purrs against your clit as he looks up at you with a grin that showed he was only getting started. The feeling of his mouth on that bundle of nerves damn near sent you into your first orgasm as you moaned his name again. "Ready to scream for me?" He asks still kneeling between your thighs. You nod with your eyes closed so you don't see him pulling out a dagger from the side of his boot. "I'm going to mark you as mine tonight, kitty. And you're going to take every bit of it because you're my good girl. Aren't you, darling?" He growls as he peppers your thigh that he's about to cut into with kisses.

"Yeah. FUCK!" You scream as he starts cutting giving you no warning whatsoever. He holds you down as you try and struggle away and soon you simply give in. At first the pain was unbearable and you squeezed your eyes shut against it during the first few letters of his name. But it was towards the end of his first name that you realized that you were squirming and whimpering for a different reason now. "Reg...mon amour," You whisper as you prop yourself up on your elbows. He was only going to glance up at you then keep going but the look in your eyes stopped him. "Are you alright, love?" He asks in a serious tone. You nod and smile as he leans up to feel of your forehead and pulse. "You're heart is racing. We can...wait. Is this turning you on?" He asks in a semi incredulous tone. You slowly slide a hand behind the nape of his neck and pull him down on top of you then kiss him slowly. "Does that answer your question?" You ask after breaking the kiss. "Mon ange noir," He growls almost in a feral tone as he grabs the dagger again. "I'm going to finish this, then I'm going to fuck you, hard, until you can't remember anything besides my name and fuck," He whispers as he kneels back down and begins on his middle name on the area that's about two inches above your clit.

The pain it causes sends you screaming his name into your first orgasm and you can hear very faintly beyond the door leading back into Hogwarts, Lily, James, and Sirius arguing about whether they should come back in and stop him. "HE'S FUCKING KILLING HER!" Sirius and James yell at the same time. "No, he isn't he's...well I don't know what he's doing but if she were truly in danger don't you think she'd be screaming for us?" Lily says in a loud voice over them. "I...well...Iunno," James says as his part of the argument dies. "If he's hurt her, I'll kick his ass without a wand!" Sirius says and you briefly hear someone else who you think is Remus comforting him and then all is quiet except for your whimpers, moans, and sighs beneath the young Black brother. "You ready for the other side?" Regulus asks as he taps your thigh and you look down just in time to see him lick the blood from where he's carved his middle name, Arcturus. "You can't fuck me before?" You ask as your eyes roll just at the sight of him with your blood on his mouth.

"No, mon amour. I have to finish first and then I'll give you a better reason to scream. You'll also be made aware of why they call me the bigger Black brother," He purrs as he licks his lips clean before repositioning himself so he can start carving his family name into the inside of your left thigh. "You're doing so good for me, Minou. Une si bonne fille pour moi," He purrs as he licks the spot where he's going to cut and then kisses it. "Fucking hell, Black!" You growl impatiently and suddenly his hand is around your throat again. "What did I say about doing that? Huh?" He whispers darkly in your ear and you can feel the knife sliding higher until it's just barely grazing your clit. "I'm sorry...I...fuck!" You manage but he's pissed now. "Oh, no. Sorry isn't going to cut it this time." He says as he lifts you to your feet with the hand he has around your throat. You wonder vaguely where he's going to take you, then a huge mirror appears against one of the walls and you get a quick glimpse of what the Room of Requirement has turned into since you two began.

Around the edge of the room is sconces that are burning dimly casting an eerie hellish orange glow everywhere. The bed you were just on, which was quite comfortable, was a black velvet sleigh bed with white sheets that were stained with large spots of blood from where he'd done his work and you'd squirmed. As he stopped you just managed to catch a glimpse of a huge floor to ceiling mirror that had appeared along with the huge table made of some type of gray wood that was about six feet in front of it. You met his eyes in the mirror and you could tell he was fighting for control of his lust as he tied you across the table. "Now, make a sound and I stop. And I know how much you love this, Minou," He says in a tone that reminds of you of something dark that wants to slither inside and consume you. You only answer is to bite your lip as he kneels behind you and begins his work once again. In this position, the pain was worse which meant by the time he got to the A in his surname you were begging him to hurry.

"Regulus, I'm sorry. Please? I need you so bad!" You whimper but instead of finishing quickly, he slows down instead causing a panicked whine to be pulled from your lips. "You want this, yes?" He asks without even glancing up at you. "Oui, je le veux vraiment," You answer in perfect French. Regulus can feel his cock straining in his pants and he knows all he's doing is torturing you both. He knows you want this, you know he wants it, but the sounds of you begging and moaning for him is almost like an addiction for him at this point. One that he knows will more than likely be his undoing and he doesn't give a damn. For the pussy that's dripping and quivering in front of his mouth, he would die. "Are you going to be a brat again?" He asks knowing full well you will. It's your favorite thing to do to him especially around Hogwarts where you two have to be careful not to be caught. Speaking of not being caught the thoughts of you and him fucking for the first time in third year in the empty Slytherin quidditch locker room was still something that he jerked off to when he thought too much about it. "No, I'll be good, promise!" You pant eagerly as you try and stay still. He smirks and snaps his fingers and the ropes tying you to the table vanish meaning there's nothing keeping you in the position he put you in, so you end up falling backwards. Regulus was prepared though and had his arms wrapped around your waist as he began eating you out from behind.
