I Became My Little Sister's Bitch Ch. 04

Wed 25th May

The mantra is looping in Bex’s ear. “You are a slut. (Yes, I am.) You are Alathia’s slut! (I am.) You live to serve your little sister, Alathia. (I do.) You want to make your little sister happy. (Yes, I love my little sister.) You crave sex. (Yes, I crave sex.) It’s an addiction to you! You crave cock. (So much.) You crave pussy. (so So, so much.) You crave Alathia’s pussy. (Yes, I want her pussy so badly.) You are a slut. (I am a slut.) YOU ARE ALATHIA’S SLUT! (I am Alathia’s slut!)

With drool rolling down Bex’s chin, the toys continue to go off and on, through the night; keeping Bex constantly on the precipice of sexual release. Pulling on her bonds, Bex yanks and yanks trying to get free from her headboard. Screaming into the ball gag, her throat burns; much like the fire that burns in her soul, Bex screams internally like Godzilla roaring over Tokyo. “Breathe, Bex, breathe. You fucking bitch, Alathia. I hate you, you fucking cunt!”

Closing her eyes to get some rest, any type of rest, from the constant assault from Alathia’s devious plan in her earbuds. Tears flow down her cheek, the reminder of her impending doom– the appointment with the piercer weighs heavily on Bex’s mind. She isn’t exactly thrilled to be getting unwanted piercings, and knowing Alathia, this isn’t some simple belly button or eyebrow piercing. She knows Alathia has a devious plan to really humiliate Bex tomorrow.

The soft sounds of her whimpers are locked behind the ball gag, keeping Bex to a mewling wretch of raw emotion. “Calm down, Bex, relax and let sleep come. Push the pleasure to the back of your mind, slip into sleep.”

Bex relaxes, slipping into a restful sleep. But the peace is broken when the toys kick back on, starting the entire vicious cycle over again. Struggling and frustrated, Bex finally passes out for a couple of hours. But only a couple hours of rest and never true sleep.

Movement catches Bex’s attention. Out of the corner of her eye, the movements of her tormentor, her little sister, and her mistress, Alathia emerge.

With an over exaggerated stretch, and an obvious, fake yawn, Alathia casts her eyes down to her big sister. “How are you, my pet, did you get a good night’s sleep? I do hope so because you have a very, very fucking busy day ahead, slut.”

Shaking her head ‘no’, the drool and dried tears still stain Bex’s face. Muffled sounds reinforce the ‘no’, as the gag prevents her from vocal communication.

Slowly stalking over Bex, the big sister has never felt so small or insignificant as she does at this moment, with her little sister standing over her like a lioness over its wounded prey; both would have the same looks in their eyes. Stroking Bex’s cheek, Alathia notices the dried drool and tears still staining her pathetic big sister’s face. With a contemptuous tone, “Oh no, my little slut, did you have a difficult night!”

With a pleading look in her eyes, Bex nods to Alathia, that she indeed had a very difficult night.

Carefully removing the ball gag, Alathia then kisses Bex’s lips, gently caressing her jaw, allowing Bex to close her mouth, finally releasing the pain in her jaw to stop.

“Thank you, Mistress.”

Unlocking the handcuffs, Alathia frees Bex from her bondage. Bex is working the feeling back in her hands, then quickly yanks the earbuds from her ears, freeing her from the constant assault of her tormentor’s mental onslaught.

Alathia teasingly dangles the key to Bex’s chastity device. “Are you ready to be free of that lovely device, or did you want to wear it during our workout?” while shaking her head no.

“No, Mistress!”

Quickly, Alathia removes the chastity device and toys from her sister’s very sensitive and wet orifices. Alathia kisses her big sister deeply, sending a spark to Bex’s very aching pussy, causing her to involuntarily thrust her pelvis into the air like humping an invisible cock. Looking at the removed toy, Alathia notices the large amount of pussy slime coating the toy.

Holding the toy in front of Bex, “Look at this. I honestly can’t believe what a slut you are, you enjoyed this, didn’t you?”

Looking down, casting her eyes away from Alathia, Bex knows the only response that won’t be met with punishment is ‘yes, mistress’.

“Yes, Mistress.”

Alathia’s smile lights up her eyes. “Get your workout clothes on, so we can go for a run.”

Bex pulls out the ridiculous workout clothes that Alathia makes her wear. Bex looking at the shorts, “These shorts are so small they should be underwear.”

Bex goes through her morning workout. The tightness of her shorts doesn’t help Bex’s still-heightened sexual state; she’s still so fucking sexually frustrated, her pussy is leading her brain.

Alathia strolls into Bex’s room wearing properly fitting workout attire. “Look at you, my beautiful slut; you were born for this.” Alathia notices Bex has put a wet spot on the front of her shorts. “Oh my god, Bex. Seriously, are you that much of an absolute slut, that you can’t control your pussy? You already put a wet spot on your shorts, hahaha!”

Bex quickly glances down, sees the wet spot, and is mortified that she can’t seem to get her pussy under control; it just keeps leaking like a fucking sieve. Bex mumbles a half-apology to Alathia.

Leaving for the run, Bex is still out of breath, but does better than she did the previous two days. Bex is still struggling to catch her breath when Alathia tells her she’s hopping in the shower. And when she’s done, Bex will take hers. “While you wait, you’ll be naked on your knees, waiting like a good pet.”

Curtsying, “Yes, Mistress.” Still breathing heavily, “My little sister’s trying to kill me. This new routine is hell and it’s only been three goddamn days.”

Stripping off the sweat-stained shirt and shorts, Bex would normally toss her dirty clothes on the floor, but this would just draw the ire of Alathia, so she puts them in the hamper. And kneels in the bathroom, waiting for Alathia to return.

Feeling the breeze from the door on her bare skin, signals Alathia has returned. Passing by her waiting big sister, Alathia pats her head. “Good girl, you’re learning very quickly. Just do as you’re told, and you’ll be treated like a princess. Don’t, and you’ll get a lot more of last night.”

“Yes, Mistress.”

Pulling off her shirt, Alathia reveals her gray sports bra underneath, tossing the shirt in the hamper. Alathia slips her shorts off, leaving herself in her sports thong and bra. Bex can’t help but longingly look at Alathia’s glistening body. The ache in her pussy isn’t helping Bex’s current state of mind. Catching Bex staring at her body gives Alathia a devilish idea.

Wriggling out of her thong, making sure her pussy is in view of Bex’s face, Alathia quickly tosses her sports bra in the hamper. Alathia sits on the toilet, spreading her legs, revealing her wet pussy to Bex. Rubbing her pussy, “Mmmm, feels good. Do you want to lick my pussy, pet?”

Blushing, Bex does actually want to bury her face in Alathia’s pussy so badly she’s almost drooling. Bex’s thoughts betray her, “Bex, from having had Alathia’s pussy lube spread across your upper lip, it’s all you could smell all night. You do want to lick her. It’s almost a driving instinct to bury your face in your mistress’s pussy.”

Alathia spreads her pussy open, showing her glistening wetness to a pussy-hungry Bex. “Come lick me, my slut, I’m so goddamn horny.”

Bex moves between Alathia’s legs, and begins licking furiously the outer labia of her little sister’s well-manicured pussy. Rolling her tongue around her sister’s pussy lips, breathing in that oh-so-familiar scent begins getting Bex’s pussy going again.

Her inner thoughts flow like water, cutting through the Grand Canyon. “God, why does this turn me on so fucking much.” Flicking her tongue playfully along the outside of her pussy, giving little nibbles along the way. Taking her mouth, Bex sucks up all of Alathia’s pussy into her mouth, rolling her tongue around the inner labia that she’s gathered into her mouth.

Causing full-on moans to escape Alathia’s lips. “Oh my, Honey Tongue, your mouth is fucking amazing.”

Still nude on the floor, Bex thinks to herself. “Fuck, maybe if I ask my mistress if I can touch myself, she’ll have some sympathy. Wait, did I just call Alathia ‘my mistress’? Fuck, focus Bex, focus!”

In the most timid voice Bex has ever used, “Mistress Alathia, may I please diddle my pussy.” Internally, Bex is screaming, “Diddle! I’m fucking reduced to using the word diddle to please my sociopathic little sister and I actually like it! Fuck Bex, fuck!”

Hearing Bex’s pitiful request, is like the hottest thing Alathia’s ever heard. Thinking to herself, “She has been very obedient today. And fuck, she is a natural pussy licker! And, diddle, I almost orgasmed on that alone.”

Between her sultry moans, “I’m not sure what you mean by diddle yourself, my love slut.”

Blushing, turning a shade of pink, “Mistress, may I rub my pussy while I lick your delicious snatch, please.” Giving Alathia her best begging look, biting her lower lip in a pout.

Giving her obedient slut puppy a head pat, “You absolutely may what was it again? Oh yes, ‘diddle’ your pussy. Now, you must thank your mistress for allowing you to touch what belongs to her, after all. Remember, don’t you dare climax either!”

Bex’s inner thoughts are damn near growling at her, for this pathetic display she’s putting on, “Fuck Bex! Begging your little sister to masturbate, that’s a new fucking low; like asking Teddy to put that buttplug in your ass was humiliating. Asking your cunt-of-a-little-sister to DIDDLE yourself. FUCK! FUCK! FUCK! FUCK YOU! This is soul crushing.”

Bex anxiously begins rubbing her pussy furiously. “So good! Fuck, I’m so fucking horny, I can’t take much more and the sister sociopath is gonna make me suffer all day again, I know it!”

Licking her little sister’s pussy, Bex is struck with an amazing idea– she keeps her favorite toy stashed under the sink. Maybe if she offers to use it on Alathia, she’ll be pleased with her.
