You shake your head, holding youe ground. “No. Sirius said your mind is poisoned. He said you said something dirty about me.”

”So what if I did?” He counters, head tilted to the right. “You are my betrothed. Desire is only natural.”

You scowl slightly, “don’t be disgusting. Mother said-“

”Oh, shut it, will you?”

You pause as your twin brother stands, his eyes boring into yours as he approaches. You look up at him, smaller, softer, weaker. “Don’t act like a child. It’s unbecoming of a woman of your caliber. Because that is what you are now. A woman. My woman.”

You shudder as a large hand trails over your collarbone, touch gentle as it ghosts over the top of your dress. His palm engulfs your delicate breast, padded with only your thin nightgown. 

“See these?” His eyes meet yours again, “you’re no child. Enough of this crying to mommy.”

You swallow, looking at the man in front of you. Looking as familiar as your reflection in the mirror. Because that is what he is. You. Only, so different now. You had almost begun to fear him. Almost.

”You should be thankful mother and father chose us to marry.” His hand lingers on your breast, eyes glancing down where your cleavage disappeared beneath silk. “Would you rather someone else? Some filthy man to paw at your sweet skin?” He squeezes the flesh tenderly, “or me? Your brother who will never dream of harming you, my sweet girl.”

“Lumus.” the tip of his wand lights up, allowing Regulus to see the disposition of your dorm. 

It’s filled with darkness and the sounds of a girl lightly snoring are the only sound that he can hear. What he’s doing is risky but he needs this, to be close to you. It’s a desperate need, a burning desire that won’t let him rest in peace.

Regulus is quick to find your bed, immediately heading towards it after shutting down the light from the spell. He doesn’t want to wake you up plus your bed is right next to the window, the moonlight casting its dim brightness over your bed.    

You're sprawled out on the bed, sheets laying half on the floor as you sleep on your side. You sleep soundly, the night gown raised enough to allow him to have a good view of your panties.

A few hair strands are glued to your face and he reaches out to remove them, his fingers taking the chance to lovingly rub your cheek. You look adorable while sleeping. 

His hand lowers down, running his fingers through your body. A pleasant warmness fills him when he comes in contact with your clothed chest, the round shape of your breast is too inviting and Regulus can’t stop himself from giving it a light squeeze.

His dark eyes immediately look at you but you remain blissfully asleep, completely unaware of his presence. He takes the chance to trail downwards towards your legs but as soon as his hand touches your skin, he’s taken by a dangerous urge.

Regulus quickly puts his hand inside your gown, pulling down your panties in a swift movement. With the lack of light, it’s hard to decipher what color they are but it doesn’t matter, they’re yours and now, his. 

A proud smile makes its way towards his face as he approaches the panties to his nose, taking a deep sniff. They smell like you and to have such intime piece of underwear of yours, makes his cock feel alive.

Regulus wants to do something, the desire to jerk off right there with you sleeping is strong but a ruffling noise of a girl moving in her bed makes him weary. 

Not today. Regulus decides as he stuffs your panties inside his pocket. He can’t stay too long, he doesn’t want to get caught in the girls dorm while holding your panties. 

Leaning down, he presses a kiss on the skin of your leg before turning around and silently leaving. 

He’ll come back another time.

regulus's fingers twitch, aching to push your hair over your shoulders and take in the unfamiliar sight of your bare skin. the milky expanse of your collarbones to the swell of your chest and expanse of your tummy. "just... just try."

“I don’t like this game,” you huff, resuming the bouncing on his hard cock. your cheeks heat as you begin to mimic the moans of pleasure you’d heard from your mother. you glance down, watching sticky strings of slick connect you to your brother as you work on top of him.

father had warned regulus and sirius against this very act. orion was possessive, especially about you. only orion was allowed to do this. it is a fathers right to claim his daughter, he’d say. and the two sons had dutifully behaved. perhaps one day they would have their own daughter.

it wasn’t until sirius had made a passing comment that the idea of fucking you took root in his mind and grew with each day. you’re twins. she is more yours than his, sirius said. and regulus couldn’t help but agree. you are his. you are his girl. you fear father. you don’t fear regulus. you love regulus. adore him. so, regulus thought that he, too, had the right to claim you.

regulus scowls, unable to resist giving sirius a childish shove. he glares venomously, “idiot. you’re not even doing it right. you don’t know what she likes.”

you let out a whimper as sirius’s cock slips out of you as regulus shoves him, your pussy on full display to their eyes. you gasp, cold air from the room sending a shiver down your spine as it blows against your sore clit. your brothers don’t dote on you as they normally would at any sign of the smallest distress, focused on their childish argument. you pout further at the loss of attention. “would you two please just-“

sirius snarls at regulus, shoving him back. “and you do?” he scoffs, pushing his hair back with one hand, the other tangling into yours, yanking the hair tie from your hair. he wraps it around his silky locks, shorter strands of his messy haircut falling from the loose ponytail.

you yelp, slapping his hand. you rub your scalp with a pout, “sirius! that fucking hurt!”

sirius ignores you, his own breath rough and ragged, his cheeks flushed a soft pink as he’s focused on your younger brother. “you’re lucky she let you fuck her in the first place. baby.”

“don't patronize me, sirius.” regulus grits, “she came to me.” a smug smile then pulls at his lips as he takes in sirius’s glare as he tuts, tugging his slick cock. “she still does. and never has she spoken a word about you all of the countless times I’ve fucked her. every time she’s milked me dry all these years... I know exactly what she likes. does that make you jealous, brother?”

sirius rolls his jaw before answering, “hardly. of course she’d go to the baby first. probably pitied your micro-“

regulus shoves him again roughly, his cheeks reddening, “I’m bigger than you.”

your older brother snorts, settling between your legs again, mindlessly tapping the weeping tip of his cock against your throbbing mound. “sure you are. you probably fuck her like a little puppy in heat. no wonder she didn’t fight me off. she’s probably ready for a real man.”

regulus murmured in his sleep, a habit he apparently didn’t grow out of. a mumbled string of your name tumbling from his lips, breathier and breathier. you started to think that maybe he was awake, trying to see if you too were struggling to fall asleep. but when you whispered his name, there was no response.

you closed your eyes, ignoring the persistent unintelligible murmurs, when you felt a twitch against your hips. you jolted immediately, trying to squirm away but regulus held tight. his nose ran up your neck as he slept, his now obvious erection pressed into your ass. you blushed, embarrassed at the contact despite no one but you knowing what was happening under the covers.

you didn’t stop it as regulus began to rut, his desperation surprising you. his pale hand moving up your chest, groping you in a way that was much too intentional for a sleeping man. you turned your head slightly, catching sight of regulus’s tightly shut eyes and parted lips. you turned away again as his eyes started to flutter open, his hips still moving with urgency.

“fuck,” he hissed, his hand falling from your breasts, his hips stopping their ruts. you nearly whimpered at that.

“I’m sorry,” he whispered, like he had known you were awake.

you didn’t respond for a moment, face half hidden by your hair. “is that why you won’t sleep with me anymore?”

it was regulus’s turn to stay silent, embarrassed to admit what you already knew. “I… I couldn’t control it. it wasn’t… I mean, it couldn’t have been you.” his nose nudged your neck, his deep inhale contradicting his words. “you’re my sister.” his cock throbbed as he spoke the word.

you bit your lip, fighting the urge to move against him. you tilted your head, giving him more access to your neck. his tongue darted out instinctively, licking your salty skin. “my sister… my twin… we’re one and the same,” he murmured, still exhausted.

you didn’t stop him as he gripped your hips, keeping you locked in place as if you had been the one to grind against his swollen prick. he pressed a kiss to your neck, hips jerking as he savored your taste. you whimpered then, skin heated. regulus groaned deeply, grinding slowly. “I only think about you, you know,” he mumbled. “I think about you when I touch my cock. you’re so pretty… always thought you were so pretty… you belong to me in every way. my flesh, my blood… my other half.”

you shuddered as he sped up his movements, now pulling on your hips to meet his twitching cock. “I couldn’t bear to sleep with you anymore. I felt so guilty knowing I was jerking off while you slept next to me… lifting your thin little nightgowns to stare at your ass… groping you… kissing you…”

you blushed, biting your lip as he shamelessly humped your ass. he continued, “I almost couldn’t resist you as you cried. when you’d lay in the floor beside me. so close. I wanted to pull you under the covers and touch you, explore you, fuck you.”

he groaned, his hand slipping between your thighs, rubbing your clit. “fuck… your pussy is so warm. you’re so warm. you’re so perfect.”

you stayed silent, letting him part your legs. you stared up at him as he positioned himself between your legs, his cock covered by his underwear and a pair of sweats while your pussy was only concealed by your flimsy panties, the fabric sticking to your folds. regulus licked his lips before his eyes met yours. stormy gray met stormy gray, blown pupils nearly making your mirrored eyes appear black. he thrusted against your pussy, completely shameless now. you allowed him, not fighting against his hands that held your thighs apart.
