The Slutmaker 6: Sandra Listens [Inc] [Mdom] [anal]

This is the sixth part in my ridiculous story of filth and incest. Previous chapters are in my post history and linked in the comments. Suggestions welcome.

 

Mandy bites down hard on the pillow as her brother violates her, tears of pain and joy streaming down her face. Unlike her mother she hasn’t had the advantage of a box of massive dildos to train herself with, her virgin cunt aches and quivers around Alex’s swollen shaft. Mandy has heard the saying “crawl before you can walk” but losing her virginity to a cock of this size was more like flying a helicopter before crawling, it was a trial by fire. But Alex is relentless, slowly forcing his cock into her virgin tunnel, ignoring her muffled squeals. Mandy thinks that Alex must be almost balls-deep inside her, but then she looks up between her legs and is shocked to see that he is only halfway.

“Oh god oh god oh god it’s so fucking big” she gasps, rubbing her clit harder.

When Alex looks down what he sees looks anatomically impossible, his sister may have a fat ass, but her hips have always been small, and he wonders how the fuck this little slut can take this much cock. At last, sweating and shaking, Mandy feels her brothers warm thighs press against her ass, and he gently strokes her ass.

“Good little fucktoy” he whispers, and Mandy smiles with pride into the pillow. He simply leaves his cock there for a few minutes, giving his sister’s cunt time to accept it’s cargo, feeling her slowly loosen slightly around him as she relaxes, breathing deep. And then it begins. Alex slowly draws back, almost completely unsheathing himself from her, and then in one brutal thrust slams all the way back in with such force that the bed rocks, slamming into the wall. Mandy squeals in pleasure and pain through the pillow, her hole body shaking as she feels him withdraw again, a slow retreat followed by a merciless charge. Alex continues like this for a while, slowly, almost imperceptibly building up tempo. Mandy gasps with relief as the pain begins to reside, replaced by a feeling of warmth and joy eminating from her cock-hungry cunt. Every fresh thrust sends a spear of thought-killing pleasure through her mind, and she knows without a doubt that she is exactly where she belongs, on all fours, offering up her perfect little holes to her brother’s god-like cock.

 

It isn’t long before she feels an orgasm rising up in her, stronger and more primal than any she has felt before. She wants to ask Alex for permission to cum, but the relentless pounding seems to have taken away her powers of speech. Finally, drooling and sweating, she explodes. Her whole body is wracked with pleasure, her arms give out and she falls face down into the bedsheets, conquered and loving it.

Mandy looks back over her shoulder at her brother, quivering slightly as the aftershocks of her orgasm run through her, reaching back and prying her cheeks apart to show Alex his handiwork. Her lips are swollen and wet, her cunt spreading just enough to show her dripping pink tunnel, a perfect cocksocket. She reaches back with her other hand, prying her fat asscheeks apart to display her virgin asshole. She knows what she wants to ask her brother, but for the first time in her life she feels shy. What if he says no?

“Ummm would you….would you fuck my ass like you did with Mom?”

Alex chuckles, placing his huge knob against the balloon knot of her asshole.

“It doesn’t work like that. Mom fucks her ass every night, if you want to be a three-holed slut like Mom you’re gonna have to work for it. Ill tell you what” Alex says, continuing to grind his knob into her impossibly tight entrance, smearing it with precum “Ill give you a special ass-training project. Every day from now on you are to stick something up that precious little ass of yours and send me a picture of it. It can be anything you want, a household object or one of Mom’s toys. The only rule is, it has to be bigger that the object from the day before. Understand?”

Mandy grins, a little thrill running though her at the idea of sending her bro filthy pics.

“Ok”

“And then, when I think you’re ready, I’ll show you what your asshole is for.”

Mandy is about to answer when Alex slams into her again, his strong hands digging hard into her ass-flesh, the heaving beast behind her panting and grunting with exertion, giving her greedy little cunt what it has wanted ever since she could remember.

Before she knows what is happening she feels him pulling her back, using both his strong hands and the leverage of his rigid cock to pull her into the air, her smooth back pressed warmly against his writhing torso, her hands grab her ankles and pull them up next to her head (silently she is grateful for all those Sunday morning yoga sessions with Mom). She had known her brother was strong, anyone could look at him and know that, but she couldn’t believe how easily he manhandled her, lifting her like she was a literal doll. His power only serves to excite her more, she squeals with glee as he begins to slam her up and down on his girth, her high pitched voice sounds like a squeaky chew toy being mauled by a dog. All conscious thought drains from her until the only thought in her head is “*I’m his slut, I’m his slut, I’m his slut*” until another orgasm is on her crashing down on her so hard that she makes inhuman sounds of ecstacy, her young body spasming and jiggling obscenely until, without warning, her brother throws her roughly to the floor, grinning down at his twitching sister sadistically.

 

Mandy feels like she’s going to die, her whole body is a useless mess of hypersensitive fuckmeat, she feels like she will never stand again, and yet one thought keeps her moving with the single-mindedness of a zombie: “*more cock.*”
On limbs made of jelly she raises herself up on all fours, shaking and drooling as she slowly turns herself around, finding her brothers massive shiny knob staring right at her, oozing pearly gobs of precum, glistening with her sweet cunt-nectar.

“Is this what you want?” Alex smirks, asking possibly the most obvious question in the universe.

All Mandy can do is nod while she stares hungrily at the center of her universe.

“Then come get it slut”Mandy crawls towards her brother, mouth wide and ready to receive his meat, but instead is rewarded with a stinging slap to the face, and Alex backs up a few inches.

“Come on slut, if you really want it, prove it….Crawl.”

Mandy begins to crawl forward, but once again is met with a hard slap and a few steps back from Alex. She feels so pathetic on her hands and knees, but she wants to show her brother what an eager fuckslave she can be. She continues to crawl, and each time is met with a hard slap, until both cheeks are red and stinging.
Tears well in her eyes, not from the pain, but from her desperate aching need to have that monster stuffed inside her again. Finally her brother reaches a computer chair at the back of the room and plops down, slowly massaging his glistening meat. Mandy lunges forward, Alex’s other hand darts out and catches her by the throat, holding her succulent mouth inches away.

“Beg” he commands, and it doesnt even occur to Mandy to disobey, even though she can only just talk through his powerful grip.

“P-please let me suck it…please, I…I want to feel it in my…in my fucking stomach….I want you to force feed… force feed me your yummy jizz…please I’ll do anything, I’ll do everything, I love having your cock stuffed down my throat, it’s the biggest fuck cock Ive ever-” Mandy stops talking, her eyes go wide while her brother’s narrow. She feels just a touch of nerves, realising her mistake.

“The biggest cock you’ve ever *what*, slut?” Alex growls, a vague threat in his voice. Mandy feels panic rising in her, knowing she can’t lie to him. How will her big brother react to finding out his sweet little sis is already an accomplished cocksucker, and a cum-receptacle for half the town. Her voice wavers slightly as she answers, her pretty eyes beg for forgiveness:

“The…the biggest cock I’ve ever sucked”

He had thought he knew all the dirty little secrets in this house. Apparently not.

“And how many cocks have you sucked, slut?”

And before Mandy knows what she’s doing she tells her brother everything about the gloryhole, about the straining, delicious cockmeat of strangers, about Mr Flynn, the teacher from school. She even takes the slutty dog collar he gave her from her pocket and shows him.

“And you take a photo with every single cock?” Alex’s tone is neutral, but there’s a twinkle in his eye that tells her she might not be in trouble after all. She nods eagerly, a small proud grin on her lips.

“Show me.”

Alex takes her phone, the first photo he sees is the last photo she took, her kneeling like a worshipper at a cum-smeared glory hole, leash around her neck, huge cum dripping smile on her face, a flaccid and drained black cock resting in her hands. It was clear that all this cum hadnt been from the one cock. Hell, it looked like more than 10 from this photo alone.
“*Holy shit*” Alex thinks as he absent-mindedly mashes his sisters face into his huge wet balls “*my sister is a fucking slut*”
Mandy groans happily into his ballsack, seeing her brother is pleased, not angered by her depraved little hobby. She had always wanted to share her slutty little project with someone, and she is so happy that someone is her brother.

 

Sandra awoke in a daze, the first thing she is aware of are her burning ass cheeks and her asshole stretched almost painfully around some foreign object. She opens her eyes but the world is still dark, something damp and heavy across her face. With shaky fingers she lifts the red panties from her face with confusion, and then it all comes rushing back to her. Flashes of her sons obscene, club-like cock battering all 3 of her holes into complete submission, his strong hands buried in her flesh, his dark blue eyes twinkling down at her as he made her his bitch. Shame and lust overwhelm her, and she shifts slighty, feeling a huge amount of some thick goo shifting and settling in the depths of her bowels. “*Oh god*” she thinks with tears in her eyes “*Thats..thats his cum. He…he came in my ass and plugged it afterwards. My asshole is flooded with my son’s semen.*” It’s then that she hears it, the unmistakeable sound of Mandy’s high pitched voice, squealing in joy and ecstacy.

“*No…no, he couldn’t…they couldn’t*” Sandra wants to deny the obvious, but she knows in the pit of her cum-flooded stomach that she is listening to her son violate her daughter. She had caught Mandy several times glancing at Alex’s crotch in the past, but had thought nothing of it. Nothing wrong with a little peek, right? But this was above and beyond. Sandra felt as if her whole carefully constructed world was falling apart, crumbling into a cum-drenched nightmare. Tears start streaming down her cheeks, but there is an undeniable wetness growing between her legs as she listens. Her hands quiver, she tries to hold back, but slowly the move towards her cunt.

 

After the sounds of depraved sex died down Sandra lay there for an hour, wondering what the hell was happening to her life. What was she turning into? What was her family turning into? Finally she decides she has to get up and have a shower to was the sex from her, to clean the last remnants of Alex’s seed from her aching cunt. She gets up slowly and dresses, her whole body is sore from the recent fuck-a-thon, the cum sloshing around in her stoppered ass is a constant reminder of her new role. She walks to the bathroom in a daze and is startled when she opens the door to find Mandy standing there, burshing her teeth with her electric toothbrush. All the colour drains from Sandra’s face as she stares at the brush. Hours before her son had violated Sandra’s ass with the curved pink handle. What would her slut of a daughter do if she knew about that? Would she even care? A devilish grin spreads over Mandy’s face as her mothers eyes move down to the collar around her neck that reads “I LOVE CUM” Sandra’s mouth falls open in shock, and just when she thinks it cant get any worse, she hears a soft dripping sound. Her daughter is wearing a hastily thrown on nightie, cum slowly oozing down her shapely thighs. As Sandra watches a fat gob of jizz drops from between her daughters legs, adding to the puddle of fuck juice on the bathroom tile. Tears spring to Sandra’s eyes, she had listened to her sweet young daughter being brutally fucked by her son, but being confronted by the reality was something else entirely.
“*I’ve failed as a mother. I’ve raised a slut and I’ve become one myself.*” she thinks as she stares down at the slimy mess. Her daughter just stands there smiling at her, and Sandra realises with a rush of shame that she is staring at the cum with hunger, that what she really wants to do is get down on all fours and slurp it off the tile. Panic rises up in her like bile, she knows that if she stands there a second longer she won’t be able to control herself, and she turns and flees back to her bedroom, slamming the door behind her. Mandy smiles to herself in the mirror

“*Stupid slut*” she thinks “*she still doesn’t understand. But she will.*”
