#stepbro!dennis

I needa go back to my roots n write more fauxcest n stepcest man. I fear I’ve lost the ancient texts… stepdad!robby…uncle!jack..sigh creepy stepbro!dennis??? IM NEGLECTING THE NEEDS OF MY PEOPLE. I needa get more freaked out well I never stopped..

like ughhh stepdad!robby who tries, he really does but when he walks by the sliding glass doors and sees you floating leisurely in the pool atop a floaty? he can’t help but stare at the tiny excuse of a bathing suit that you have on. the way your tits are practicing spilling out from the top, nipples clearly visible through the fabric. how it leaves absolutely nothing to the imagination. how he’s sure that if he had his glasses on he could see the curls that peek out from the sides of your bikini bottoms. how pretty your legs look shimmering in the sun. he attempts to banish any inappropriate thoughts from his head but when you stretch out crossing your legs? he’s done for. openly fantasizing about how easy it’d be to untie those bows holding everything together. it’s even worse when you unintentionally make eye contact with him. perking up and waving, a devastatingly pretty smile on your face as you call out a sweet “hi dad!” he tries and fails.

or uncle!jack who can’t help but smile when he comes around to hang with robby. because you, in all your sweet summer glory loves to stay around the garage while they work on their bikes. asking questions n helping when you can, bending over to gather tools for him. the swell of your ass peeking out from under your shorts in a way he really can’t ignore. you’re sweaty too, he can tell, he can smell it. when you first leaned in to hug him the aroma hitting him all at once, that was when he initially arrived and even more so now as you walk about the garage. the somehow sweet smell making his mouth water, he sees it soak the underarms of your shirt, drip down your neck. and sees it make a perfect imprint of your thighs and ass in the fabric of the lawn chair you were sitting in as you chatted with them over the neck of the wine cooler in your hand. his eyes locking in on it immediately after you had got up to grab yourself another. you were mouth watering, truly..and his best friends daughter.

and stepbro!dennis who loves you, so much. always wanted a sister really. he’s the sweetest thing ever. but god do you tempt him. in the blazing sun of early june wiping down his dads truck accompanied by you. suds and water flying about as the two of you are far more interested in getting the other soaked. dennis armed with the hose and you a bucket of soapy water. it was innocent really, you splashing cold handful’s at him causing him to retaliate by dousing you with the frigid water was all in good fun. until he saw how the water soaked right through your short sundress. the material clinging to your body becoming ever so see through. the color of your panties visible along with the clear outline of your breasts. no bra, he immediately noticed and it made him swallow hard. he’d never seen so much of you before so he stared..and stared. then came more water until you were laughing and dripping. droplets tracing your legs collecting in a puddle at your feet. none the wiser to his prying eyes.

and suddenly “just looking” turns into “please let me touch you just a little”

18+ content

Stepbro!Dennis has been itching to touch you; his sneaky glances of you as you shower or change are just not doing it for him as much anymore. He wanted to see you fully naked—standing still in front of him so he could commit every detail to memory. He was becoming obsessed, and he figured asking wouldn’t hurt.

You knew about the peeping he did on you, but you didn’t care. You found it kind of flattering—even adorable sometimes—when you would catch his eye through the crack of a door. So when Dennis came to you one day whining, “Can I please see you naked?” with the biggest puppy dog eyes ever—well, it was hard to say no.

One day when everyone is out of the house except for you two, you let him guide you to his room. He stands there nervously for a moment before you speak, “Are you going to take off my clothes, Denny?” you smile teasingly. “Yeah—yeah—I just—I’m a little nervous,” he admits with an awkward chuckle. “It’s okay, c’mere.” You hold out your hand for him to take, guiding him to your shirt when he does. “We can do it together, yeah?” He nods in response.

He steps close to you and brings his other hand to the bottom of your shirt before carefully pulling it off you. He lets out a breath at the sight of you in your bra, reaching forward before hesitating. “Can I take it off?” he asks, looking you in the eyes. “Of course... I want you to,” you respond, getting a little antsy yourself. He reaches behind you, his hand finding the clasp, and he struggles a bit before the hooks finally slide out, the bra coming loose.

You let him slide it off, your boobs now on display as it hits the ground. He sucks in a breath, hands twitching like he’s itching to touch you. “You’re so beautiful,” he mutters, almost as if he were talking to himself. You smile, reaching out to touch his face. “Thank you, Den.” He smiles back, moving his hands to your waistband, biting his bottom lip.

You nod at him, moving your arm down so he has room. He slowly slides your pants off, his fingers brushing all the way down your legs as he does so, the action making you shiver. You step out of the pants and stand before him in just your underwear; he marvels at the sight of you. “Can I touch you, please?” he whines, and you think about it—for too long apparently because he’s begging, “Please? I’ll be good.”

Your cunt throbs at his persistence, and you cave. “Yeah—okay, Denny, you can touch me.” He lets out a breath of relief, saying, “Thank you so much,” under his breath before his fingers come in contact with your skin. His fingertips dance over your tummy, and you giggle a little when it tickles you, making him laugh. He then uses his whole hands, stroking over your waist and up to your boobs.

He’s incredibly gentle with you, fondling the soft skin and watching for your reaction. Your nipples harden under the touch and slight chill of the room, causing him to bite his lip in satisfaction. “Dennis,” you murmur softly, and he catches your eye before you both lean in, your lips meeting in a heated kiss, his hands gently squeezing your boobs. You squeak and giggle as you pull back.

“You’re so pretty; have I told you that?” he teases as he rubs his hands up and over your shoulders. “Maybe once or twice—but I’m still not fully naked, you know,” you grin. He stutters at that, his gained confidence halting for a moment. “I know,” he starts nervously, “I just—I’m not sure if I can hold myself back… seeing you like that.”

“It’s okay, I trust you,” you tell him, moving to pull lightly at one of his curls. He takes in a deep breath, nodding, before trailing his hands back down your stomach, rubbing his fingers over the light strip of hair leading under your panties. Finally, he pulls them down, bending his knees to slide them all the way down to your feet. When he glances up, he’s in perfect line of sight with your cunt. “Holy fuck,” he blurts out before his hands move to grip your thighs.

Looking down at him nervously, you can’t help but sigh in relief when he looks up at you with pure lust in his eyes. “Please—please can I kiss her? She’s so pretty,” he begs, practically salivating at the thought of getting his mouth on you. “Jesus—yes, please,” you hum, almost vibrating in want. He dives in quickly, softly kissing at the hood of your clit before sucking it into his mouth, his nose rubbing against your pubic hair.

You both moan in tandem, and your hands fly onto his head to stabilize yourself. “Dennis—” you groan as he licks up your wet hole and smears it over the rest of your cunt. “Tastes so fucking good,” he blabbers, completely losing himself in you. You start to fuck his mouth, grinding against his face and pushing his head into you. He moans loudly against you, the vibrations making your eyes fall shut and lips go slack.

this one is really really HEAVY on the stepcest so..be warned. hes a creep!! and a little mean!!

⋆˚✿˖° | stepbro!dennis who absolutely adores you and how you dress, act and conduct yourself. those short skirts that have the bottom of your ass peeking out, low waisted jeans that show the pretty straps of your thong that sit on your hips. if he were being honest you were like a wet dream come true. even at home you’d prance around in too short damn near sheer night gowns that left nothing to the imagination. ones that he couldn’t stare at too long or he’d get hard almost immediately. what made you even better in his opinion was the fact that you were so incredibly affectionate with him.

⋆˚✿˖° | you had taken a liking to him almost immediately, finding him absolutely adorable. and you’d always wanted an older brother! so when stepbro!dennis made it clear he loved spending time with you as well. you were absolutely elated and with that elation came affection! the physical kind, hugs when you were excited at something. bringing the man into your arms tightly and swaying side to side as you rambled off about your topic of choice. completely oblivious to how his hands tightened on your waist and how his nose skimmed up your neck. inhaling your sweet scented perfume.

sticky glossed kisses pressed to his cheeks and sometimes the corner of his mouth. leaving a shiny smear on his flushed skin. hell you’d even find your way into his room to lay about on his bed while he was in there. casually laying next to him while your long nails clicked on your phone screen. the pink of your short set contrasting with the navy of his comforter. it was a simple routine—well to you anyways. not once noticing how you drove your poor brother up the wall. it was like you were trying to tempt him but stepbro!dennis knew better, you were just a bit air-headed. and once he realized how little you seemed to..think. he slowly got bolder. just to see…

⋆˚✿˖° | first it was simple, letting his hands wander. laying in bed next to him? your head on his shoulder, he’d rest a shaky hand on your bare thigh. sitting there before he carefully slid it to the inner part of it to give it a little squeeze. the feeling of your soft skin beneath his palm had him twitching in his boxers. after, he even began to trace shapes into the skin. to which you’d just hum and reply with a content;

“your hand is warm den.” never taking your eyes off your phone.

then it was during hugs, his hands going from your waist..lower and lower and they were right on the swell of your ass. fingertips inches from going beneath the shortness of your skirt. his chest heaving as he tried to gauge your reaction. leaning back and looking at you, who was smiling all the same with a playful look in your eye before you leaned in to whisper.

“you tryna feel me up or somethin’?” paired with a giggle and a shake of your hips. your copious amounts of jewelry jingling with your silly movements.

“maybe?” his own bashful honesty surprised him.

another laugh, “but denny..m’your sister?” it was all playful coyness. pushing his buttons and straining his resolve— well more like smashing them with a hammer and sawing them in half.

he swallowed harshly, adams apple bobbing in his throat. hands moving lower still.

“step. technically..”

on movie nights he’d start off with your legs in his lap. then transition to gently tugging you to sit atop him sideways so your legs could still rest on the couch. you happily accepting being so close to your sweet brother having no objections when he pulled you closer. stepbro!dennis who shuddered at your proximity and weight. one hand around your back and the other sandwiched between the heat of your thighs just resting there mere inches away from your cunt. so close in fact he could feel the weight radiating off her. shifting his legs to attempt to keep you off his growing boner.

it even turned into him peeping in on you in the shower, you had a bad habit of leaving the door cracked. gazing at the pornographic outline of your body through the semi sheer curtain. or while you changed, not that you didn’t already change in front of him.

often padding into his room to have him help you pick out an outfit. not bothering to make him turn around while you stood in your matching bra and panties asking his opinion on this and that.

“like, wait— can you see my ass when I bend over?”

before he could speak you were already turning around to arch your back the smallest bit. mock bending over to show him. dennis gulped, throwing a pillow over his lap as he gazed at the absolute eyeful you were giving him. a clear view of your perfect panty covered ass that was obviously on show when you bent over.

the panties were simple, pink with white hearts and a lace trim. from how you were positioned he could see the outline of your pussy. right there..basically in his face. his leg began to bounce.

“uhm..yeah you can.” he coughed.

“how much? like everythin’?” you look back at him over your shoulder, those pretty false lashes fluttering at him.

his eyes stayed on the curve of your ass and backs of your thighs as you asked. tugging his lip between the blunt of his teeth as he slowly nodded. mind too preoccupied with imagining what your cunt would look like if he were to yank down those useless panties of yours. if he spread the lips of your no doubt perfect pussy to take in all you had to offer. he thought about pushing you down to the floor, lifting up that useless denim item you call a skirt. and grinding into your ass until your underwear was soaked through. not the thoughts he should be having but you make it incredibly hard to be a good brother.

“pretty much..” he muttered.

noticing the far off look in his eye and strain in his voice you perk up. turning to look at him from where he sits on his bed.

“you’re such a perv!” it’s said with absolutely no malice or disgust. just pure amusement like he wasn’t two steps away from fucking you silly.

“s’not my fault..”

on those nights you’d make yourself at home in his bed, often falling asleep. stepbro!dennis would..indulge a little. gazing at and admiring the peaceful look on your face as you slept, bonnet slightly askew and lips parted. it would have been sweet with how he fixed the satin on your head before running his thumb over your lips.

would have.

if it weren’t for how his eyes lingered on the edge of your night gown, the material riding up your thighs enough to have him heating up. it was late..his door was locked. it would be fine.

the aforementioned thumb slipped between the petals of your vaseline covered lips to dip into your mouth. he lets out a breath as he moves it over your tongue. feeling the saliva pooled in your mouth coat his finger, it was so incredibly supple inside. slick and smooth as he prodded around. freezing when your brows momentarily scrunched before relaxing. he traced over your teeth, the underside of your tongue and your inner cheek. all the while leaking precum into his pajamas.

bringing his thumb out he admired the web of spit connecting you to him before quickly sticking it in his mouth to suck it off. smiling around the digit as his hips bucked at the taste.

this was wrong..disgusting, perverse. but those facts only spurred him on. a sick enjoyment washing over him in a new arousal he’s never felt before. he just loved you so much and you loved him too right? all those signs you were giving him had to be just that, signs. his pulse hammering in his ears as his gaze went back to your night dress. the tops of your thighs so pretty in the dim light of his room. so with a final glance at your face he moves closer.

lifting the fabric enough to peek under.

“holy shit.”

his eyes immediately zeroing in on your cunt, covered by the soft cotton of your panties. this time they’re grey and white striped. a bow sat on the waistline, simple in contrast to your usual blingy fashion choices

he could see the way your curls peeked out the edges of your panties and it made him sweat. taking a finger he swiped over your slit, reveling in how your sleeping body reacted. hips twitching beneath his touch.

a few more swipes, presses and prods of his finger had him growing to full hardness. his chest felt so tight, you’d notice if he took them off right..? he shouldn’t even be doing this. only looking no touching. but dennis wasn’t as strong as he seemed. traveling up he pulled your dress the rest of the way until the hem was beneath your chin. bare breasts exposed to him.

maneuvering himself he gently sat over you, straddling you while staying up on his knees as to not put any weight on you. taking both hands now he started on your thighs skimming them up your body.

feeling every curve, dip and scar your figure had to offer. he was properly panting now, breath coming out in hot puffs as he felt you up. over your waist..stomach and stopping to palm your breasts. kneading the soft flesh. flicking over your nipples to watch you writhe. how could you be so soft..? probably that extensive body care routine he sees you do sometimes, all that cocoa butter did you well.

he was so consumed in his groping that he didn’t notice your eyes fluttering open. until you were speaking.

“denn..y?”

his eyes widen to side of dinner plates. hands ripping from your body like you were made of corrosive acid.

his mouth suddenly dry he says the only phrase that comes to mind.

“s-sorry for wakin’ you..”

instead of screaming like he expected. you whined sleepily reaching out for his hands immediately placing them back on your tits. batting your lashes at him.

“don’t stop…feels nice, please?”

“o-okay..”

∘•················•∘

before he knows it he’s prodding you open with the leaky tip of his cock. sliding his shaft through the wet folds of your pussy, the flushed head bumping your clit making you whine out. his thumbs gently spreading you open, gaze intensely staring at your cunt. the way you twitch and leak all over him, as he slides against you.

“holy fuck..you’re perfect..wanted this f’so long..y’know that?” he pants. “all that teasin’ please tell me you wanted it too,—me too..”

“y-yea i..ah—did uh huh!” you nod, words stuttered and broken up.

“this is so bad…i shouldn’t—we shouldn’t be—“ he whimpers, feeling his tip catch on your entrance. it makes his brows furrow as he bites down on his lip. “basically my—my sister..”

you let out a breathless giggle “step t-technically..?” mirroring his words from earlier in the week.

dennis huffs out a laugh, grinding the tip into you as if we was going to slide it inside. he wants too..you’re so soft and slick, it would be so fucking easy for him.

“hey..” you blink up at him, hands sliding up his shoulders to thread through the curls at the base of neck. “you s-should let me put it in..” it comes out as a desperate whine. he groans, feeling your hole twitch right over top his head.

your hips jump, chasing the sensation. pushing down towards him as your fingers dig into his shirt. tugging him forward impatiently.

“you sure..? we don’t have a..condom.” he grits his teeth.

“i…i can pull out, please..sis?” he leans his head down, desperately licking up your neck in long wet trails. pressing kisses into the skin, rocking his hips into yours. ever so slightly pushing inside making your fingers dig into his shoulders with a gasp at the stretch.

“just a little..the tip okay, promise it’ll feel s’good..you’re already this wet.”

hesitating before you give a nod, even with all your teasing you didn’t think he’d take it this far. to the point of genuinely wanting to fuck you..although you’re not complaining. the guilt mixing with the arousal swimming in your veins.

“knew you wanted it..” he mumbled with a smile against your cheek.

you chance a look down realizing just how..big. he is, you felt it before but now it’s completely different. you swallow slowly growing nervous that he wouldn’t fit.

“wait— what if it doesn’t—“

“it will..”

the sound of your agreement throws him over the edge. pushing inside you slowly, feeling your tight, wet pussy stretch around his cock. opening up for him like he imagined so many times, bottoming out, he’s buried completely inside you, your warmth squeezing down on him.

your hand flying down to rest atop your lower stomach. right where you feel him fill you up. not to stop him just to feel him, even as he pushed past just his tip.

“y-you said just the—“

“accident..sorry, slipped in..”

∘•················•∘

and now here he was, fucking into you in a way that could only be done after months of built up tension. months of sneaking touches and peeking on you coming to a head. each time he felt his cock drag against the sticky velvet of your walls with every deep thrust. his palm had covered your mouth a while ago to not alert your parents, you yourself unable to hold back your whines of his name.

“oh my god— you feel so good, s’good.” he groans “does it feel okay?” his voice is weary, laced with uncertainty, he is still your big brother after all.

you nod behind his hand, teary eyes blinking up at him. whimpers dampened. so he lifts his palm giving you a chance to speak.

“it— you’re so deep..!” you gasp, eyes watery.

dennis's face lights up with relief and renewed desire. bending down to kiss your forehead gently, his thrusts becoming slower and more deliberate trying not to get over excited.

he dreamed of this so many times and now that he’s here. instead of succumbing to his fantasies he attempts to take his time with you. in hopes that maybe in the future you’d let him touch you again..even if he was the one feeling you up in your sleep. this is his way of making up for it.

sorta. its what he tells himself anyway.

“that’s good but..it doesn’t answer my q-question..” lips brushing against your temple.

you swallow, licking your lips and nodding. trying to find the words that seem to disappear every time they form. your hands move up to mindlessly grab at your bonnet as you focus.

“feels so good, den..promise, promise it does.”

he kisses your cheek, your nose, your lips. “you know i love you... so much...”

“l-love you too..!”

“being inside you s’like a dream..love it so— much, y’squeezing me so damn tight.” he babbles. “gonna go faster alright?”

before you can speak he’s leaning back, sweat slicking his hair to his forehead in a dim shimmer. also thoroughly soaking his shirt. pooling at the collar, the scent mixing with the already aromatic smell of sex permeating his bedroom. it makes you dizzy, always having loved his smell. hoisting one of your legs over his shoulder he gives you a lopsided— sex drunken smile. before snapping his hips into you, making you choke out a moan. immediately covering your own mouth as you stare up at him.

“fuck, you take it so well.. the—the whole thing too..told ya i’d make it fit..guess you’re just as bad as me ha..”

the pace he sets makes your eyes roll back, hammering his cock into you with a sloppy kind of precision. trying to make it as good for the both of you as he could. his bed creaking in a way that, if someone was listen in, would be a dead give away on the deplorable acts taking place between a pair of psudo-siblings.

“mm shi— den oh fuck you’re— ah!” your moans are incomprehensible. filling your stepbrother with a certain kind of pride. the kind that comes from making such a pretty girl like yourself scream yourself hoarse on his cock.

“yeah?” he huffs out a laugh from his chest, airy and light.

leaning down, your leg still over his shoulder. he kisses you, for the first time ever. lips slotting messily as you swallow down each others whimpers, his tongue messily sliding over your teeth and down into your throat. greedy— that’s how he was kissing you.

“you—mmph—like when your brother fucks you?”

you whine “denny! don’t be so gross!”

“m’not..” he huffs, annoyed.

his spare hand drops to your slick puffy clit, circling it with his thumb. applying steady pressure as he rocks into you. determined to make you finish.

“please cum for me..be good like you have been..” he mumbles..not to you but to your cunt. it sends maddening shock waves through you. your hips bucking up towards it and away at the same time making it difficult for him to keep a handle on you.

“god, hold—still!” in an act of annoyance he meanly pinches your clit between his fingers, and that’s what does it for you. the orgasm hitting you like a brick to the head. sending your head forward to bring him down in a kiss. as your back arches, cunt squeezing him in warm pulses. coaxing him to cum alongside you, milking his shaft until he’s swearing against your lips.

cock twitching wildly before spilling his warm cum inside, coating your walls. so much for pulling out..

“den—! you didn’t..!” you whine tapping his shoulder.

“shut up..”

he moans putting his lips back on yours effectively silencing your cries. his fingers continuing their assault on your poor clit until you’re holding back sobs.

“fuckfuckfuck” he whimpers. hips still shallowly rutting into you. emptying out all his load and then some, your pussy still stroking him from the inside out. he pulls back, spit connecting his lips to yours as he pants. face red and looking down at your fucked out expression. chest heaving he runs his hands over your tummy and to your tits. palming them softly as he stares—slightly dazed.

“y-you came inside..”

“sorry..” and he was, kind of.

he pulls out and back biting back a whine as his softened cock slips from your spent cunt. pushing the leg on his shoulder back, and bending it till its up towards your chest. doing the same to the other one, watching as his milky cum seeps from you slowly.

“whoa..ok uhm” he leans over to his nightstand collecting a hand full of tissues “..p-push it out”

“..what?”

he sighs, “just—just do it okay?” voice soft yet urging. you nod, sniffling before doing as he says. contracting your cunt to slowly push his cum out and into his hand. when it does he rubs at your leg.

“there we go..” he swallows, mesmerized at the sight of it. “lets get you cleaned up, yeah?” eyes flickering from your pussy to your glassy eyes. “m’sure we can make it to the bathroom without mom n’ dad waking up.”

“okay..”

oh that I do my dear anon..that I do. heavy stepcest yall kinda dubcon-ish?? you have been warned. he’s also kinda evil.

dennis was fighting in a war he knew he shouldn't be on the front lines for. it was a battle that he should have denounced and immediately sworn off. a battle fueled by shame and lust. one that had you at the forefront of it, the cause of his inner turmoil. any time you were around he swallowed hard, throat bobbing harshly as if his esophagus was lined in sandpaper. mind racing with scenarios, outcomes, reactions, any and everything that could be a result of this —this urge that had been building for months, growing stronger every time you were so much as in the room with him.

and he hated himself for it.

but he was so..curious. that’s what he told himself, so incredibly curious about you—your body. how it would writhe and squirm beneath his touch, his tongue. what it’d feel like to finally touch you.

⋆˚✿˖° | stepbro!dennis who walks by your room with the intentions of getting water from the kitchen. it’s late, so the rest of the house is still sleeping. the hallways quiet and lights off, on his sluggish trek he notices that your door is cracked. a warm dim light spilling from the gap, no big deal sometimes you forget to close it. and just as he’s about to continue on he hears the smallest of whimpers. his eyes widen and he takes a step back—quietly. socked feet avoiding the rickety floorboards to peer into your room. the noise sent a shiver down his spine and heat up his back. the closer he got the more the soft sounds he heard. he swallowed harshly as he looked into your room, eyes immediately finding you.

⋆˚✿˖° | laid out against your pillows, knees up and spread with your shorts down around your ankles. you didn’t even take the time to slide them all the way off. shirt pulled up and tucked beneath your chin exposing the swell of your breasts that heave with every deep breath you take. stepbro!dennis who sees the way your hand is between your legs, although the view is obscured it doesn’t take a genius to understand what you’re doing. you look so..pretty. the thought makes shame twist in his stomach. paired with the burn of arousal shooting straight to his crotch, making his cock twitch beneath his sweats.

⋆˚✿˖° | stepbro!dennis who can’t take his eyes off the way your hips roll onto your hand, how you tremble beneath your own actions. he bites his lip chewing down hard on the skin. your eyes are closed and brows furrowed in concentration. those same soft noises dripping from your parted lips. if he focuses hard enough he can hear how wet you are and it makes saliva pool in his mouth. his mind immediately drifting to what would you tas— nononono. this is disgusting..this is not what he should be doing, you’d be mortified if you knew he was watching. your big brother no less, peeping in on you touching yourself like some sick pervert. he sighs, knowing he should just turn around and—

“den..denny” you sigh.

⋆˚✿˖° | oh fuck. your voice is so sweet, so.. pitiful. calling out to the man that was already there with you. the call of his name sends him into a silent frenzy. the half boner he was sporting now proudly tenting begging for attention. it aches already, from his need to touch or the shame bubbling beneath his skin he can’t tell. so against his better judgment stepbro!dennis slides into your room, silently clicking the door shut behind him. he gently calls your name which in turn makes you sit up in shock, your face etched in horror and suprise.

⋆˚✿˖° | stepbro!dennis who puts a finger to his lips wordlessly shushing you. stepping across your carpet to stand next to your bed. eyes trying their hardest to stay put on your face.

“uhm..do you—want some help?”

AHHHH GROPING ONE OF MY FAVORITE TROPES OR WHATEVAAAAA. you know me so damn well anon mmmwah!!

⋆˚✿˖° | stepbro!dennis who always finds an excuse to stare at your tits. not that he really needs an excuse though. because even if he didn’t he still would. eyes constantly falling towards your chest no matter what you wear. taking in the pretty shape of them, how they sit so pretty below your collar bones. he especially likes it in those slow, quiet mornings when the rest of your conjoined family is asleep and you’re sleepily brushing your teeth in bathroom. him catching you as you lean over the sink with the white foam from the toothpaste’s dripping down the side of your mouth. droplets landing on the tops of your breasts which are exposed due to the thin camisole you wear. nipples showing through the thin fabric.

on multiple occasions he’s had to rip his eyes away from them during conversations with you. entranced when they bounce ever so slightly.

⋆˚✿˖° | stepbro!dennis who loves how affectionate you are for him. how you let him get close when your arms open to hug him. pressing him close to you and in turn pressing your perfect tits to his chest. it makes him lightheaded even just the soft pressure against him has his cock twitching pathetically in his briefs. a smear of precum no doubt staining the plaid material. cheeks heating up and ears flushing a pretty red.

⋆˚✿˖° | stepbro!dennis who knows you have a little thing for him. that makes you so easy for him. you preen at his touch eyes bouncing around his face trying to make out what he’s thinking when all that’s on his mind is getting his hands on you. and you let him, every single time. allowing him creep into your room at night to pepper your face in kisses as he slides his warm hands up your night gown. palms immediately finding your tits to squeeze at them, fondling the warm flesh. breath fanning hotly against your lips from where he sits across from you. panting into the kiss and head swimming with how warm you are. kneading into you a little rougher, fingers running over your nipples in a way that makes you whimper lowly into his mouth. squeezing and rolling them between the pads of his fingers a little meaner to make you squeak.

switching between gently flicking and pinching them. he whimpers with every touch he gives you, the weight of them in his palms unlike anything he’s ever felt before. no matter how many times he does this. he’ll never get tired of it.

⋆˚✿˖° | when you let him lay atop you as you rest on your couch or the bed stepbro!dennis buries his face into the warmth of your breasts. sighing as he sinks into the valley between them. your scent enveloping him while he gazes up at you. then once again his wandering hands peel up your his worn out old t-shirt. tucking the hem between your lips with a smile. then moving down to suck your tit into his mouth. his hips immediately bucking on your thigh at the taste of your skin. he just about melts while he does this, warm tongue dragging his spit all over your nipple until you shiver whimpering his name. humming over it eyes occasionally flickering up to rove over your pleasure contorted face. his free hand groping your other breast because what kinda brother leaves his sister neglected?

i feel like with stepbro!dennis he would get really possessive and be groping you all day, maybe even moving your bottoms to the side to snag a peek at your cunt 🤭

with bf!dennis and stepdad!robby i think dennis would try to control himself since he doesnt wanna make a bad impression on your stepfather. but robby is shamelessly ogling you, staring directly at your boobs when talking to you, or asking you to sit on his lap while he's hard as a rock 🤭 bonus points for some tummy mention because my mind is still reeling from that tummy shot in the trailer 😵‍💫

stepbro!dennis would be all OVER goin to the beach with you. absolutely elated as soon as you bring it up, not just to see you half naked but in general just to have fun. mostly to see you half naked

warnings: fauxcest, stepdad!robby, stepbro!dennis.

so like your family definitely has one of those big ass beach tent things that you can’t see inside of and he’s using that to his advantage. offering to help you moisturize sunscreen into your skin, using it as an excuse to get handsy. once you’re laid out his hands are all over you, back, arms, ass, thighs, legs. resting his knees over the back of your legs so you can’t get up before pulling your bottoms to the side. “den—dennis! what are you doing? mom and dad could be back any second.” comes your panicked whines trying to push the man off you. “m’sorry just..you look so pretty I just wanna see okay?” youre huffing about it but you relent.

he leans down nosing over the back of your neck, inhaling deeply. the smell of salt on your skin and your sweat is enough to have him half hard. his tongue peeking out as he licks down your shoulder. “you’re so gross!” ignoring you he continues moving down your back in wet streaks. lifting your arm and sticking his nose there, where the scent of your sweat is the strongest n licking there too. him panting all the while, you squeal, the sensation a confusing mess of arousing and horribly ticklish. continuing his earlier practice he tugs the bottoms to the side coming up off your back to peer between your legs. the peek he gets sends a shiver though him. bringing his spare hand down to pull apart the glistening mess “wanna taste you..you’re wet.” a finger slides through your sticky mess, ever so slightly pushing against your hole “can’t den, you know that— you said just a look!.”

he’s basically pouting knowing you’re right. but god if this isn’t the hottest thing he’s seen. holding his sister down and touching her to his hearts content. the previous half boner he was sporting now growing into a full hard-on. he likes it, loves it even knowing that he isn’t forcing you but the fact that he could..and you’d like it is enough to have him just as wet as you.

maybe he even slides his cock between the cheek of your ass and the swimsuit, rutting against you until he’s spilling all over your lower back.

now, for stepdad!robby he definitely noticed dennis’ behavior towards you, mostly because he was staring too. with his darling stepdaughter running around in scraps, how could he not look? you’re breathtaking. young and pretty, it makes his cock twitch from where he sits in his folding chair. watching you and dennis splash around, unfortunately for you though all the running around loosens the tie on your top. causing you to rush out of the water and back into the tent and past michael with a yelp. while dennis tries to hide his obvious boner robby is gently asking if you need help. and of course your nodding with a “yes please.” voice shy n low.

ordering you to sit on his lap so he can retie it for you has you happily obliging. plush thighs on top of his firm ones, covered in course hair that makes you squirm. “gotta come closer honey..s’okay.” large hands grip your hips sliding you back on his lap. his soft tummy presses to your back and his hands begin to work at your top. all your squirming making him groan, “stop moving.” “sorry..” the friction making his dick kick to life in his shorts pressing against your cunt. “robby you’re—“ he hums out a low “shh”

“your fault for all that moving baby.” once he’s done you try to get up but his palms keep you still. “give me a sec honey, I need to calm down before you get up.”

imagining both of them perving on you all day is so fun. maybe dennis even intentionally loosens the straps of your bottoms while you both swim. so he has an excuse to go under water and “look” for them. which, there is no looking he grabbed them they second they came off. he just wants to look, n maybe even finger you in the water who knows!!
