#stepbrother!regulus

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.”

your cheeks begin to burn, feeling grateful for the fabric of your skirt obscuring his view of you. “I haven’t…”

“good,” regulus lays a wet kiss along your clit. “it’s not okay to have thoughts like that about your brother…” his tongue dips down, drawing more slick from your clenching hole, “I’m doing this to help you, not to have you thinking disgusting thoughts about me, you sick little angel.”

you bite your lip, “I don’t. it just hurts… always hurts…” regulus hums, the vibration making you whine softly. you can’t help the small jerk of your hip, aching to pull him closer.

“I can see that, angel,” he murmurs, slick sounds coming from beneath your flared skirt. “it’s so messy down here… drooling all over my tongue…”

you spread your legs, planting your feet far apart as you displayed your pretty cunt to your father. regulus nearly groaned as he saw the slick folds, the familiar sight of your little clit and clenching hole making him want to barge inside and take you first. he clenched his fists, his dull nails sinking into his palm as his father leaned in, inhaling the sweet aroma of your arousal, his tongue flicking your folds only once. you squirm.

“are you only going to kiss it today, daddy?”

oh, regulus almost moans at that.

you always shook your head when regulus demanded you use that name for him and now he knows why. you had been moaning it to your father instead, letting him lick and suck on your pussy without a word of protest, likely waiting obediently for regulus or sirius to summon you, too.

“no,” orion chuckles, pressing a peck to your inner thigh, “you’re getting fucked by daddy today.” orion stands, sliding off his belt and unbuttoning his pants as he stares at your exposed pussy, his greedy fingers occasionally sliding up your glistening slit. “are you excited, sweet girl? dad hasn’t fucked this little cunt in a long time, right?”

you nod, “yes. not since mom came back. sirius said you don’t like me anymore.”

regulus’s jaw ticks. sirius had known but hadn’t bothered to tell him. he’d give him an earful next time he saw him.

regulus focuses again. his fathers cock isn’t as long as his, but it’s girthier. regulus knows you’ll cry. you always do when sirius fucks you, stretching you wide rather than deep like regulus’s long cock does.

regulus is correct, of course. you start to cry as soon as orion’s tip stretches your little hole but you don’t dare complain. regulus finds that a little odd. you did nothing but whine and complain whenever regulus hurt you, moaning about how he was too big, too rough, too much. it almost makes him wonder what your father had subjected you to when you did complain. the thought is oddly thrilling.

his father doesn’t move very fast, his aging body leaving him to fuck you slowly, lacking the youthful eagerness that he and sirius have. his silver hair starts sticking to his forehead as he spreads your legs further.

“oh, babygirl…” he groans, tossing your knees over his elbows, “look at you… such a sweet thing… your mom hasn’t been this tight in ages.”

regulus can’t help it then, sliding his hands down the front of his pants. he massages his cock, nibbling on his lip as he watches you fight the urge to whimper and squirm, a distant thought of his father and mother tangled in their sheets, engaged in sin.

your eyes flicker back to your bed, regulus stormy eyes now fixed on you. he remains as expressionless as he always is, but there’s a small flash of amusement within them that disappears as quickly as it appears. you don’t speak for a second, your lips glued shut as your blood runs cold from the mere intensity of his gaze.

before you can mutter out some unconvincing excuse, he speaks again. “come here.”

you swallow thickly, the feeling of dread heavy in your stomach. you take slow steps towards him, drawing out the time before you walk right into his arms.

you stop as your knees hit the edge of your mattress, the thick bedding brushing your skin. you look up at him, finding his eyes fixed on the flowing skirt you suddenly regret slipping on in the morning.

his hand slides beneath it, his touch splayed over the plush flesh. “I said come here.”

you had known what he meant. you knew that he wanted you to climb onto the bed and perch yourself on his lap. to present yourself to him and give him access to you.

you climb onto the bed, taking deep breaths to calm yourself. regulus taps his fingers against his thigh, his eyes locked on you as you move. you swing your leg over his lap and sit down, your hands clasped together in front of you like an obedient trained dog. you watched as his eyes roamed over you, filled with hunger and lust.

his hands rest on the tops of your thighs, roaming over the expanse before dipping to the inner area, squeezing the flesh there. he pushes the hem of your skirt up, baring even more of your skin to him but what catches his eye is the baby pink panties hugging the lips of your pussy. his thumb brushes over the front, right over your slit. you jolt at the touch, your hand twitching to push his touch away but you manage to keep it in place. regulus brushes his thumb against you again, the pad of his thumb circling the area where your clit sits, his head tilted to the side and his eyes glimmering with smug, mocking amusement.

“you were out late,” he murmurs, glancing back down to where his thumb now circles your clit through your panties. “where were you?”

“it’s mary’s birthday,” you say softly. “she had a few people over.”

regulus hums, disapproval laced within it. “and you went.”

you nod, already knowing what’s to come.

“in this… skirt.”

you nod again, muttering a halfhearted excuse, knowing he won’t believe you anyway. “the others were… dirty.”

regulus looks up at you, not the slightest bit surprised by your attempt at deception. “ah, yes. I’m sure all those appropriate dresses in your closet are so filthy.” he moves your panties to the side, parting your pussy lips and exposing your inner lips to the chill air.

you know what he’s doing. he’s inspecting your cunt, making sure no one has touched what he believes he’s entitled to. what is his.

his finger slides between the folds, the tip prodding at your dry entrance. he hums, pleased. “were you a good girl tonight?” he looks up at you again, his eyes locked on yours for any sign of hesitation.

you nod your head, but you’re words come out slightly fearful. “yes… there were… boys there,” you pause to watch regulus’s reaction, noting the subtle clench of his jaw. “but I… I didn’t talk to them, I promise. I walked away every time.”

“good,” regulus says, giving your clit a light pinch that makes you jump and hiss in discomfort. “wouldn’t want to give you another lesson so soon. think you had enough last time, huh? taught you real well.”

you stay silent, letting his touch roam your pussy. he sticks his fingers into his mouth briefly, coating his digits to aid his gliding hands exploring your tense body. his eyes flash with satisfaction and lust when your hole begins to drip with your essence, raising his fingers to your mouth that you obediently take, sucking them clean.

“that’s a good girl,” he purrs. “look at you learning so well already. you’ve only been here a few months and look at how obedient you are…” you think back to his cruel punishments, knowing better than to disobey.

he pats the side of your thigh. “lay down. you’ve earned a nice reward, sweet girl. would you like that?”

your stomach feels heavy but you know better than to show it, instead nodding your head and moving off his lap. you slowly lift your shirt over your head, slowly and teasingly as regulus has taught you. he lets out a small groan, his hand raising to paw at your tits, squeezing them and ghosting over your pebbling nipples.

you lay down next, sliding your skirt off before slowly peeling your panties away, baring yourself. regulus rises to his knees, still fully clothed. you spread your legs wide, allowing him to see your pussy completely.

“good girl,” he emphasizes, yanking his pants down just enough for his cock to spring free, hard and leaking like it always seems to be when you’re around.

“no crying this time,” he says, his heavy cock slapping your clit. “I hate when you do that. I could be a lot meaner than I am and if you keep up all that weeping, I won’t hesitate to show you.”

you nod again, bracing yourself for his inevitable harsh thrust, impaling you completely with one swift move. “I won’t… won’t cry. I’m… I’m strong.”

a single tear trickled down your face as you watched his hand moving up and down, slick with the copious amount of leaking moisture from his own prick. he nodded once and you shakily reached for the clasp of the bra, a sob escaping you as the straps fell down your arms and onto the floor. regulus’s hand moved faster, his lips catching between his teeth as he gnawed on it, his gaze now fixed on the pebbling nipples of your chest and the goosebumps that rose along the swells of your breasts.

“come,” regulus murmured.

you let out a whimper but oblige, your knees brushing his as you came to a halt. you held your trembling arms at your sides as regulus uses his free hand to grope your chest. he tweaks and pulls on the pert nipples and kneads the doughy flesh of your breasts.

“f-f-fuck,” he groaned, his lips locking around one nipple, sucking as he felt his balls tighten. he stopped, panting around the nub of your tit as he fought off his orgasm, not ready to release just yet.

he looked up at you, your teary eyes locking with his lustful gaze. his cock twitched in his hand at the sight and the waft of musky arousal that came from your center. he laid a gentle kiss to each of your breasts as his hand tugged the lacy underwear down your legs. you looked at him with despair and distress, knowing what was to come.

regulus leaned back against the sofa, patting his leg. “sit.”

he sent a warning look when he saw you about to perch yourself on his thighs instead of where he knew you knew he wanted you. your lips trembled and you shuffled farther up, your now bare pussy hovering over the weeping tip of his cock. you looked at him again, awaiting the command, stalling.

“I’m not doing it on purpose,” sirius responds, his teeth still grazing your throat before nibbling lightly. “why would I touch you when we have this pretty little thing right here?” his hand slithers down your side, squeezing your hip. you drop your head forward, landing on regulus’s cold shoulder.

the shoulder tenses as regulus snaps at your older brother. “you grabbed my ass!”

you snort between a moan as sirius’s hips never stop their thrusts into the tight ring of your ass. you push your elbow back, jabbing his side. “dick.”

sirius hisses, biting your neck harshly. “he’s a prude, sister,” he mumbles in your ear.

regulus scoffs, his hips delivering a harsh thrust that makes you gasp. “am not.” he lays another soft kiss on your shoulder in apology. “I just don’t want you to try to put your finger in my ass. again.”

you feel sirius shrug behind you, grunting deeply as he pushed his cock as deep as he can go. his hands grip your hips, your flesh bulging through his fingers. “no fun.” he lifts his head, chin on your shoulder as he gives regulus a grin, eyes half-lidded. “you can grab mine.”

regulus huffs in disgust but his cheeks flush a light pink. “as if. that’s disgusting.”

sirius raises a brow, one of his hands leaving your hip to tilt your head towards him, giving you a deep lingering kiss. “fucking your sister isn’t?”

regulus flushes brighter, burying his face in your neck to hide the pink hue. he starts circling your clit again, making your knees go weak. you moan into sirius’s mouth as he gives you another kiss. “leave him alone,” you say, a small grin on your face despite your words.

“don’t act like it’s not something you’d like to see,” he murmurs against your mouth. “he’d like it, too. bet I’m real t-“

your eyes stay glued to the sight before you, regulus's leaking cock swinging above your face, occasionally catching on your lips for you to suckle at the endless beads of precum, sirius's taut balls repeatedly slamming against regulus's reddening backside.

"oh... merlin, reg..." sirius hisses under his breath, his voice deep and velvety as he fucks into regulus eagerly. you feel regulus grunt against your pussy, his tongue poking out to lick your swollen clit. you moan softly, feeling your hips buck upwards, his nose dipping between your folds, your juices likely smearing across his flushed skin.

“j-just… h-hurry up…” regulus pants, the octave of his voice giving away his arousal, “she… she gets the point.”

sirius scoffs, pressing his hips into regulus further, “tighten up then, would you? I haven’t loosened you up already, have I?”

regulus makes a noise you know too well, a groan of embarrassment as he struggles to come up with a retort for sirius’s words. sirius chuckles, moving his hips rhythmically again, the squelch of his cock slamming into regulus’s tight hole growing faster and louder.
