Marissa looks into the floor mirror and sighs as she slips her uniform shirt on over her shoulders. She was hoping to make it out of the house before anyone else woke up but she can already hear rustling from the room next door. Her brother, Liam, must be awake and he's certain to give Marissa a hard time. She looks down to start buttoning the shirt with a resigned purse of her lips. Nothing she can do about it now but finish getting ready.

Moments later, Marissa's bedroom door swings open behind her with a shout that visibly startles her. "Good morning, li'l sis!" Marissa clenches her teeth in annoyance from the loud shock and turns to see the unwelcome intruder.

"I'm gonna be late to work, okay? Just let me get dressed." She knows the appeal will fall on deaf ears but it's still worth a try. Now facing him, she can see that he's only wearing a wrinkled t-shirt and no pants. His hand is clearly wrapped around his erect cock but it's obscured by a piece of fabric that's wrapped around it beneath his grip.

"No can do, slut! Don't you know what day it is?" His smile only widens at her acknowledgement of the inconvenience he's about to cause her. "It's the first day of my new job! Don't you want to celebrate?" He's slowly jerking his cock off with the piece of fabric while he teases Marissa. After a moment's inspection, she realizes it's one of her panties that he must have stolen earlier. One of the expensive, black silk pairs that's certain to be ruined with his stains by now.

She turns her back to him again and pushes down the urge to let all her frustration out. "All that new money... Maybe you'll finally move out to your own place, huh?" Her hands return to buttoning her shirt in an attempt to ignore Liam. Her regret for not waking up earlier keeps building, now standing in her room in her bra and panties with only a half-buttoned shirt on.

"Aw, don't be like that." He steps up behind her and runs his free hand over the curve of her waist. "If you don't wanna celebrate properly, at least bend over like a good little cock sleeve." He presses the silk-covered head of his cock against her, rubbing the tip up and down against the panties she was wearing, pushing the fabric between her ass cheeks, before sliding his cock between her legs to prod at her pussy from behind.

Marissa sucks in a tiny breath at the feeling of his hard cock toying with her but she tries to not let it show. Liam is undoubtably an annoying prick but they both know how much they enjoy the free use laws giving him permission to use his sister, or any woman, any way he wants. Even more than using her as his relief toy, the laws permit any man to snuff and dispose of her at will. It's simply expected that a sister will help relieve the pent-up cocks in her family and Marissa can't help but enjoy it. She's certainly annoyed with how much glee Liam takes in interrupting her life but she can't deny how wet it makes her when she's reminded that she's ultimately just walking fuckmeat to him.

"I wasn't asking, cunt," Liam snaps her out of her thoughts. He grabs her by her hair and pushes her down over her bed beside the mirror. "My cock's been hard since waking up, thinking about all the fresh holes I'll get to try at my new job. All the servile little sucksluts crowded under my desk, licking my nuts and calling me 'boss'..."

He presses the side of her face into the mattress with one hand on her head while his other hand quickly jerks her panties down to her thighs. Marissa squirms slightly to turn her head to a more comfortable angle but otherwise doesn't resist. She simply pushes her hands against the bed to brace herself beneath his forceful arm and spreads her feet wider apart until her panties are pulled taught between her thighs.

"Isn't your new title like... 'inventory associate'? I don't think anyone's going to be calling you 'boss', Liam..."

He doesn't respond. For all she knows, he's not even listening anymore. He's busy staring down at his still-covered cock as he uses his other hand to rub the tip up and down his sister's cunt lips. After appreciating the way her soft lips spread and squish beneath his cock's head, he starts rubbing further up and down as he continues his day dream. Marissa can feel the damp silk of her stolen panties slide up her slit to prod at her exposed asshole before sliding all the way down off her clit with a flick.

"Maybe I *will* move out, soon. But it's way too convenient having you around to use as a cum toilet. I'll just have to convince Dad to let me take you with..." Liam ponders as he keeps absent-mindedly teasing his cock back and forth between his sister's familiar holes.

"Fat chance," Marissa responds quietly. Her pinned body gives a small jerk every time his covered cock head flicks off of her swelling clit but she remains still otherwise. She knows it's best to just let her brother have his fun and relieve his morning load without too much interference.

Liam lets out a long sigh at the daunting prospect of convincing their father to give Marissa up. He finally commits to a hole and presses the head of his rigid cock against the entrance to her cunt harder, the silky fabric of her panties still wrapped over him.

"H-hey, wait! At least take my underwear off your cock first, dumbass," Marissa strains to look behind her but his hand pinning her head to the bed makes it impossible.

Liam responds by momentarily letting go of his cock and giving her exposed ass cheek a hard slap. He quickly returns his grip to his shaft and presses the tip back into his sister's hole. "I mean, why the fuck not? He owes it to me, right?" Liam asks the questions rhetorically as he stares down at the sight of his cock entering his morning toilet. She knows that's all he sees her as, right now; the free use bitch he happens to be using for his own relief. Any brotherly niceties from before are long gone.

"All my friends had a ton of sisters to enjoy. And here I am, stuck with just one fucking set of cockholes to share with Dad and every other guy you beg to fuck your idiot brains out..." His voice gets noticeably more angry as he goes. With a frustrated growl, he leans his weight forward more, pressing the side of her head into the bed harder and forcing his thick cock past her tight, wet entrance.

"F-fuck! Take them off... before you fuck up my hole!" She continues her pleading for at least some restraint. Her hips rock a bit beneath him, grinding her clit against the edge of the mattress as best as she can

"Don't get me wrong. You're a premium piece of fuckmeat, sis. Just a real depraved fucking cock addict when you're not being such a whiny little bitch." Liam stops with a grunt after pushing his entire cock head a little ways into her. "Do you have any idea how hard it is to get my cock into you when I'm using your panties as a condom? Be useful and at least spread your fucking holes, lazy cunt..."

Marissa clenches her teeth to keep from making too much noise. Her silk underwear wrapped over his cock is making this all a lot harder than it needs to be. But that's naturally her fault, according to him. So she reaches her hands back and wraps her fingers around her ass cheeks to dig her fingertips into the soft flesh to either side of her cunt. She obediently pulls her hole open wider for him, knowing that fitting the rest of his cock in won't really be any easier.

"That's it, fuckhole... You love this cock more than anyone else's, don't you? Just like a good. little. bitch. sister!" He punctuates each of his last words with a rough thrust of his hips, hammering his cock further into her each time. At last, his cock is fully buried in his sister's stretched fucksleeve, the folded silk of her panties spilling out of the edges where they meet.

"Christ, that's fucking tight!" Liam groans his pleasure out from overhead. Not that she can really see his expression from how hard he's pressing her head into the sheets. He finally leans back and releases her head suddenly enough that she springs upward slightly. "Mornings are so much better with a warm, tight cunt stretched over my cock, you don't even know..."

One of his hands grabs onto her hip for leverage as he slowly grinds his cock around inside her, enjoying the feeling of the tight silk pulled over it as much as her insides. His other hand reaches down to grab at one of her tits roughly. He gets frustrated with the clothes in his way and yanks at the shirt before long, popping off the few buttons she'd managed to fasten. Then he slides his hand beneath her bra cup from below and gropes at her soft breast directly.

"Yup, nothin' better than this. You're really missin' out, sis. But that's hardly my fault you chose to be born as a cock-addicted fucksleeve." He leans his head back with the words, relishing the feeling of his birthright to treat his sister as a disposable jerk off toy first thing in the morning. He's right that she doesn't know what it's like to have been born with a cock to bury in every fuckable hole that walks by. But that doesn't mean she's missing out.

If he had been paying any attention to her, he might notice that she's currently panting and drooling against her sheets. Her hips are still bucking beneath him, giving her sensitive clit a rough ride against her own bed while his thick cock grinds around inside her hole just how she always loves. The taught fabric of her panties being forced up her cunt even adds an extra element of pained pleasure to the otherwise mundane affair of getting her brother's morning load fucked into her.

With a content sigh from her brother, Marissa can feel Liam start to relieve his bladder deep inside her. The hot stream being forced through her panties to fill her aching cockhole makes her shiver with pleasure. The pleasure of a thick cock unload inside her. The pleasure of being a useful relief hole for her brother. The simple pleasure of getting her cunt stretched first thing in the morning, even if it makes her late to work again.

"Mm fuck, that's good... Just missin' out, sis. Not knowin' what it's like to wake up every morning by pissin' up a little retard's hole... God! You make my nuts fuckin' ache, bitch!" Liam flips from relaxed to aggressive as soon as his stream slows. His morning piss had long since started overflowing from Marissa's over-stuffed cunt, pouring out around the edges to soak her stolen panties, the edge of her bed, her thighs, and her fresh panties stretched between her thighs.

"You're such a rape-baiting little whore, you know that?! You've always been such a stupid cumsleeve but you can't even thank me for shoving all this fucking cock up your worthless bitch hole?" His hand clawing at her tit moves back up to her head, grabbing her hair and pulling it back forcefully. At the same time, he drives his hips forward, pinning her legs and stomach to the bed as he forces his cock as deep as he can into his sister's tortured cunt.

"Maybe I should just fucking kill you now. Such a waste of grade-A fuckmeat but at least I wouldn't have to put up with you making my cock ache so fucking much all day just from looking at you. Do you get off on being such a useless little retard?! Fucking thank me for pissing in your guts, bitch, before I pull your head so far back you can watch me rape the life out you!"

Marissa gasps in air, her neck constricted from the severe angle at which her brother is pulling her head back. She tries to respond but her voice is raspy and weak, catching in her throat when Liam quickly draws his hips back and slams his cock back into her.

"Tha-nk... you," she forces the words out. He growls in pleasure and frustration behind her and she feels like he might really break something in her neck as he pulls slightly harder. Then he lets go of her hair entirely without warning, letting her head drop forward to land on the soft bed.

"You're welcome, cunt," he says with most of the aggressive tone gone. Instead, he seems genuinely content with the current outcome. His hand that had been in her hair moves down to her free hip, his grip tightening around both. He begins rhythmically slamming his hips against her soft ass, pulling back on her body each time to impale her on his cock deeper and harder. She hears his groans and pants from behind her getting louder and less controlled after just a few thrusts.

"That's it... Tighter, sis! Use that fuckin' cumhole!" Liam sounds increasingly desperate as his balls tighten and his cock swells. Marissa's face is buried against the bed to muffle how loudly she's moaning. With how carelessly he's ramming her ruined panties into her body, she can't help but to squirm and pull at the sheets. But even as he slams her cock-addled brains out, she still has enough sense to squeeze her cunt tight, to be the best possible jerk off sleeve for her dear brother's morning load.

After burying himself into his live-in jizzhole to the hilt, Liam presses his body down against her back with a strained sigh. His hands move to the back of her head, pressing her face harder into the mattress while his weight keeps her lower body firmly pinned between the edge of the bed and his cock. He grunts deeply each time his cock sprays a heavy rope of cum deep into her cunt. The creamy load splashes against her soaked panties but quickly leaks to fill her hole directly, his grinding and humping against her helpless body with each shot ensuring that her abused hole is thoroughly creamed.

"Always hits the fuckin' spot, sis." Liam practically purrs the words as he stands back upright, pushing himself up with his hands still pressed to the back of her head. He looks down at where his cock is sheathed inside his sister's blasted fuckhole and grins through his panting. He thrusts back and froth slowly a few more times, enjoying the slick mess he's made of her insides, before sliding his half-hard cock all the way out.

He gives her ass a quick slap of approval that snaps her back to reality. Marissa gasps in a deep breath before moaning at the hot ache in her guts. He reaches down and holds the crotch of her panties between her thighs up with his palm. Crouching slightly, he wipes his dripping cock clean across the cotton, adding to the splashes of cum and urine and cunt juice already there.

"Anyways, I better head off to work. Don't want to be late on my first day, after all," Liam says casually as he finishes dragging his cock across the inside of her thighs to clean it more. He quickly wipes both his hands across her sheets to either side of her with some finality before striding out of her room, leaving her bent over her bed with scraps of her ruined panties hanging from her freshly-fucked hole.
