I Became My Little Sister's Bitch

Sun 29th of May

The blindfold is new, Bex thought to herself. She has lost track of time, not knowing how long she has been out here, and the heat she's experiencing is also a new experience. Alathia has her strapped down to a sawhorse by all fours.

Thinking back, she'd thought she'd seen Alathia angry, by being caught in the diaper and completely failing Alathia's orders.

"How long have I been out here naked, strapped to this sawhorse, being teased by toys, the magical wand is strapped to my clit, teasing me. I swear she's fucking diabolical. And the penis gag is working my jaw something fierce. It's gonna be hella sore."

The scraping of the metal door opening, alerts Bex to someone approaching. Bex feels the fingers caressing her nude body, the sultry voice of her mistress greets Bex.

"Hey, sexy, I'll bet you'd love some water?"

The penis gag makes her head-nod look more like a seal begging for fish. Then suddenly, the gaga is roughly snatched from her mouth; the sudden, freeing sensation is abruptly interrupted by a pair of soft lips spitting a mouthful of water into her eager, wanting throat. Frantically, Bex uses her tongue to gather every drop of water.

The process is repeated in eerie silence, until Bex's thirst is satiated. Finally having taken enough water, Bex croaks, "Who... who... who's... there?"

Having the blindfold ripped off, Bex sees her little sister in all her glory. Her long black hair is done up in a style similar to Anna from Frozen. Alathia's green eyes burn with an intensity that could snuff out the sun. Her short-sleeve blouse is stylish, and the comfortable pencil skirt is immaculate.

The light radiating behind Alathia blinds Bex; seeing her mistress in all her glory, sends Bex's heart and other areas aflutter.

Tears are rolling down her cheek. "I'm... sooo... so... sorry... mis--"

Alathia cuts off Bex with a powerful slap, the hit rocks Bex's head, cutting off her apology. She snarls, "SHUT UP, YOU STUPID CUNT, I'M SO DISAPPOINTED IN YOU! You are not to speak again 'til I say so; you only answer when asked a direct question; nod if you understand, cunt?"

Bex feeling the sharp pain and warmth growing in her cheek, nods her affirmation.

"Seems that the studying is working for you, not as stupid as you used to be." Alathia caresses her big sister's tear-stained cheek. "I'm so disappointed in you, my love."

"Love, yes I knew it she does love me, I let her down, I disappointed her, I'm a disappointment."

The hours baking in the hot shed have done a tremendous job breaking down Bex, both mentally and physically.

Alathia begins caressing her big sister, "Bex, I'm so sorry, my love, but I have to discipline you for your transgressions; you've broken multiple rules, so you must be punished."

Bex, still struggling to clear the fog from her mind, just nods on instinct; making Alathia very happy at her little sister's current physical and mental state.

"God, I'd admit to anything to get off this sawhorse and out of this fucking oven. Every inch of my body is screaming in some sort of pain or pleasure; to be honest, I'm starting to not be able to tell the difference."

Alathia caresses her reddened, tear-stained cheek; kissing her lips, Alathia begins gently probing her tongue deeply into Bex's mouth, breaking the kiss,

"I love you, my big sister, I'm really sorry for what I'm about to do, please know this hurts me so much more to do to you then it hurts you."

Strolling around Bex, Alathia runs her well-manicured purple-nailed fingers over Bex's sweat-stained body.

"You know, for lacking in the tits department, you actually have a really cute ass, big sister. Doesn't it bother you that you've basically become your little sister's personal maid and sex slave?"

"Yeah, I was hoping for a summer of fun, not housework and whoring!"

Alathia moves around Bex, circling her like a great white circling its dinner. Alathia grabs a harness off the wall tauntingly, as the raven-haired sister swings the bit in front of Bex, who watches the harness go back and forth.

"I'm gonna give you permission to speak after I explain why you want me to put this on you. We're in our backyard in the shed, to be more specific, so it's definitely gonna echo if you scream; drawing attention to you being naked, strapped to a sawhorse, would be an interesting sight for someone to find. But... If you beg me really nicely, with a pretty please on top, I'll put this on you to keep you quiet. Now, you may speak."

"I swear, it's like she works from the CIA playbook of breaking someone down!"

"Mistress, may I please wear the harness? I don't think I can keep quiet, I wouldn't want to attract the attention, Mistress."

Alathia places the horse bit into Bex's mouth, strapping the leather harness into place around her sister's head.

The leather straps bite into her cheeks. "Fuck, where does Mistress, fuck, I mean my cunt-of-a-sister find this devious shit; seriously, I'm wearing a horse bit and I've no idea why!"

Checking that the straps are secure, Alathia caresses her big sister's cheek-- it's still warm and red from the slap she delivered a few minutes ago. Satisfied that the harness isn't going to slip off, Alathia almost skips back to the wall, picking a leather strap off one of the hooks. Alathia begins twirling the strap, taunting Bex, showing her the implement she intends to use on her bound victim.

The realization of the moment slams into Bex's consciousness, like a car slamming into the back end of a Yugo on the four-oh-five. Frantically, Bex begins struggling, trying to free herself from the bondage of the sawhorse. Bex wants no part of being whipped by her Mistress's leather strap.

"Oh god no... please don't whip me; fuck, why is my pussy dripping? I'm so afraid and yet my body wants her to use that strap on every inch of my body."

Seeing the distress and sudden jerking movement to get free, Alathia takes the end of the strap, using it to raise Bex's chin. "Oh, you don't want to feel the kiss of my leather strap, huh, cunt?"

Shaking her head, Bex relays that she doesn't want her sister to use that on her, but what's more frightening is that Bex really does want her sister to use it on her-- the fire between her legs doesn't lie.

"Oh, you don't want to taste my leather strap-- it's going to happen! I'm sorry, my love, but your behavior needs correcting."

Looking directly into Bex's eyes, Alathia never breaks eye contact as she brings the first lash across her back.

Bex's face blossoms with a look of pain, and pleasure explodes with another scream that's stifled from the bit in her mouth.

"Did that hurt, my pet?" Stroking her cheek, Alathia brushes a tear from her big sister's cheek. "Oh my poor, poor cunt-of-a-big-sister, are you finally realizing your true nature?"

"True nature, what in the world is my miss-- FUCK! Alathia her fucking name is Alathia-- and what the absolute fuck is wrong with my little sister."

Caressing her hand down Bex's back, Alathia's finger plays with Bex's buttplug. It's a new plug. It's a little bigger than her previous plug, this one says 'open for all' on it. Alathia checks the wand, making sure it's still placed snugly against her clit. Pulling a little on the plug elicits a pleasurable groan from Bex's gagged mouth.

Alathia slips a finger deep into Bex's wet pussy, and checks the straps holding her securely to the sawhorse, which is now stained from her pussy fluid seeping out. Alathia pushes another finger into her big sister's snatch, working a few quick pumps, gathering some of her big sister's pussy slime. She smears the gathered fluid across her big sister's upper lip, so that now all Bex can smell is her own excitement.

"Oh god, my own excitement is flooding my senses and further pushing me to a sexual frenzy."

"Look at you, your pussy's dripping, no normal person would be this turned on being treated like this unlessss... She truly was a depraved slut, wouldn't you agree, SLUT!"

The gag prevents any verbal communication, but Bex feels the weight of her little sister's words come down in her psyche, like the leather lash across her back leaving an emotional welt on her self-esteem. Bex is feeling her sister's proclamation. "No... no, she's wrong... isn't she... isn't she?"

Bex's introspection is absolutely interrupted by another lash, this one landing firmly across Bex's ass cheeks. The bit wedged in Bex's mouth does its job, holding back another ear-piercing scream to a muffled whimper and whines. Before Bex can fully register the blow to her ass, Alathia has landed another three lashes on her sister's ass in the exact same spot; almost amazed at the level of precision and skill needed for such a feat. Bex is frantically struggling with the pain-and-pleasure cocktail that's now growing in her wet snatch.

Stroking her big sister's cheek, Alathia kisses her big sister's forehead tenderly. "I don't enjoy this, Bex. I'm doing this for you, Bex, so you'll be better and will make me proud. I know it must seem like I'm cruel and mean to whip you with this leather strap, but unfortunately, it's necessary to get you back on the correct path to correct your bad behavior. You understand, right?"

Bex, just grateful the lashes have stopped, nods her affirmation that she understands through tear-filled blue eyes.

Looking deep into her big sister's eyes, Alathia states, "This is just foreplay, my personal fuck-toy; now, it's time for the main event."

Bex takes a deep breath, preparing for what her little sister has now called the main event. Alathia, with mastery and precision, begins assaulting her big sister's body with the leather strap. As the feeling of her orgasm begins to overcome her, Bex begins losing consciousness; the last thing Bex remembers, is her little sister removing the bit and carrying her out of the shed.

*********************

Bex, groaning, slowly regains consciousness, feeling some rather larger breasts pressed into her back, being engulfed in a pair of silken arms cradling her aching body.

"Shhh, it's okay, my love, I'm taking care of you and your sore body." Nibbling her big sister's neck, Alathia says, "I'm gonna kiss your pain away," before gently caressing her big sister's body, using a very soft and expensive washcloth.

Hearing the sultry voice of her little sister, lover, mistress... Bex feels the soft material caressing her skin, soaping every inch of her body, taking care not to aggravate the very angry red welts on her back and ass. The bath bomb oils and bodywash all mix, giving the Reid sister's unique fragrance of fruit and wildflowers.

"Oh my, Bex, your cute little ass is so red with welts. If you're a good girl, I'll put some ointment on it before you go to bed to help soothe the pain."

"Yes, Mistress."

"Holy shit, this is so weird waking up, in my Mistress's loving embrace of me."

"Thank you, Mistress."

Taking Bex's chin in her grasp, Alathia plants a very passionate kiss. Alathia continues using the wash cloth on her big sister's body, caressing the red welts on her big sister's back. Alathia kisses them softly, tenderly washing them to not bring her big sister any more pain.

Working her fingers along Bex's rib cage, Alathia begins tugging on her big sister's nipple rings. The golden snake wrapped around the erect nipple holds the ring that locks the whole piercing in place. The golden piercings are amazingly ornate, with the snakes having slivers of rubies for eyes, and silver fangs in the open mouth biting the ring.

"Oh fuck, she's playing with my nipples, and oh my god, I'm so fucking horny. I honestly want Alathia to sit on my face while she licks me to an amazing orgasm."

The tugging begins to draw some very salacious moans from her big sister's lips.

"You may want to be quiet, my love. Aunt Tracy and mother are still home, I believe they're having wine in the living room."

Biting her lip, Bex struggles to keep her moans stifled. "Yesssss... yesss... ye-- Mist-- Mistress."

Feeling lips on her neck, sends a shiver through Bex's body. Gentle scrubbing of the nipple jewelry, moves her attention to her stomach.

"Oh god, seriously? My mistress is driving me crazy. I'd plunge two fingers in my pussy right now if my mistress would allow it! These are the moments that I love about being owned by my mistre--"

Alathia stops teasing poor Bex's erect, hypersensitive nipples, granting the very turned-on big sister a small break. Alathia begins washing her sister's back again, careful to avoid the red welts.

"Oh that's nice, and as much as I want more from my mistress, I'm grateful to have a small break from Alathia's constant teasing and edging my own sexual excitement. Why does her touch drive me insane? It's like my body has become completely addicted to my little sister's touch. I would spend the rest of my life in her embrace, if it was like this all the time. Does she love me?"

Bex turns to face her little sister, kissing her, plunging her tongue deeply into Alathia's mouth, exploring and searching for her little sister's tongue. Slowly, Bex begins massaging Alathia's breasts, her ample chest has always made Bex jealous. She begins by cupping them in her hands, then brings her little sister's nipple to her mouth, suckling the erect nub.

Feeling her big sister's hands cupping her boobs, Alathia kisses her sister back, plunging her own tongue deeply into her big sister's surprised mouth. The kiss is paired with Alathia slipping two fingers into Bex's very wet snatch, catching the older sister's first moan in her little sister's waiting mouth.

Tipping her head back, Bex gasps in pleasure, "Ohhhhh... fuuuuuck... ohhhh... Mistress."

"Oh, you dirty cunt, are you enjoying your baby sister's fingers, hmmm?"

"Oh god, if she only knew the feeling of her forcing water deep inside me is hitting all my spots, and I'm a mess just begging for release."

Pulling on her little sister's nipples, Bex groans a purring moan, "Yes, Mistress... oh god, yes... "

Alathia groans, "That feels so good, pet, you're being such a good girl. You like pulling on my nipples, you like playing with real breasts?"

"Oh god. Yes, Mistress, I love your breasts. I'm so jealous of your figure."

"I hate her for this. She knows I hate being so flat chested. Everyone thinks I'm Alathia's little sister, not her big sister."

Grabbing her big sister by the back of her hair, Alathia positions Bex so she's bent over the large, two-person tub.

"Oh shit, I get all wet when she does this; I'm like putty right now. I want her to touch me so badly." Bex, moving almost instinctively, reaches back, spreading herself open for her little sister to use.

Alathia is playing with the plug still in Bex's ass. "While you were unconscious, I switched out your plug to a new one that we won't have to pull out anymore; we can switch the ends to whatever I want. Isn't that exciting, my fuck-toy."

Feeling her little sister's fingers working their way in and out of her spread pussy, Bex moans softly, "Yes, Mistress, ohhhhhh... that sounds very exciting, Mistress."

"I can feel her fingers exploring every inch of my pussy. She's rubbing her fingers along the plug's firmness. It's so fantastic, it's pouring the intensity on my already carnal fire."

Gently caressing her big sister's cute little ass, Alathia gives her big sister a playful swat to her butt. "Look at you, spreading yourself open like a bitch in heat. You fight me by saying to yourself this isn't who you are; you keep saying to yourself, she makes me, it's not me... I'm not really like this."

Bex is feeling the pleasure spread throughout her body. Alathia runs her free hand up Bex's spine, gripping her hair with a sharp yank back on her head. Bex groans again in pleasure, having her hair being pulled while her sister fingers her pussy. Alathia slips a third finger into her sister's now-very-wet-and-ready cunt.

"Look at yourself in the mirror, slut. LOOK!"

Bex finally sees the full-length mirror reflecting her pleasure-filled expression back at herself, the carnal lust is practically screaming from her face and expressions. The sight of her being used by her sister, and thoroughly loving it, is another shot to her crumbling psyche and self-image.

"Look at the bitch in heat in that mirror; what self-respecting woman would be aroused by her own little sister degrading and humiliating her?"

Bex is still coming to the realization that it is her who is that woman; she is what her sister claims her to be. "No, no, no, no... yes, it's true that she's not forcing me to... no, she's, she's... she's..."

With a primal sexual growl, Alathia demands, "Answer me, slut. What kind of woman behaves in such a manner?"

"I... I... don't... know... Mistress."

"I do, cunt. A fucking slut, who only thinks with her pussy-- keep looking at the mirror, cunt!" Alathia continues her assault on her sister's pussy, watching her big sister's climax begin to erupt through her body."

"Oh shit, oh shit... she's right..."

The intensity of her climax causes Bex to pass out, with the image of her climaxing to her sister's touch burned into her mind...

**************

Alathia carries Bex into her newly decorated bedroom, where she lays her sister down. Searching through her sister's new wardrobe, Alathia picks some very cute sleepwear-- the shorts say 'porn star' across the butt, and a tiny midriff tank-top, both in a pale pink. Looking down at her slumbering sister, Alathia brushes her sister's hair off her face, then gives her a gentle kiss on the forehead, as she exits her little sister's newly remade princess-pink room.

"Mother really pulled out all the stops to get this done. I have to admit that she didn't even question the remodel, she only gave that side grin she does sometimes, and why is Aunt Tracy here?"

Opening the door to her room, the Sanctum Santorum, Alathia begins unbuttoning her blouse, tossing it into her dirty-clothes hamper. The chill of her room caresses Alathia's bare skin. The black-lace half-bra is quickly discarded in the hamper, as well.

"Bex better take care of my laundry tomorrow, she's already been sloughing off her usual chores!" The skirt is the next thing Alathia discards, leaving her just in her thong. She plops down in front of her laptop she has affectionately named, the Lament Configuration. She runs her well-manicured fingers over her custom keyboard-- themed after Star Wars, and more specifically, a tribute to the Sith-- the keys glow red and the boot-up sound is a light saber being ignited. The case is black, trimmed with red LEDs.

A few, quick keystrokes, and Alathia is into her computer's desktop. Clicking on the shortcut, Alathia is prompted to enter her password, after which, she pulls up the cameras she has planted throughout the house. She zooms in on her big sister's room-- the cameras and microphones are working perfectly. So good, in fact, the mic picks up Bex having a rather salacious dream.

"l "Oh fuck, this is my father's cock I'm sucking and I've never been more turned on in my life. I truly hope Mistress is gonna fuck my slutty ass, I'm so fucking horny!"

"Look at you, whore, have you been practicing your cock-sucking technique?"

"Yes, Mother Harlot, I've been practicing deepthroating that monster cock you left me as a parting gift."

"I'm gonna beat your ass 'til my arms are tired, and your ass is gonna be black and blue, and you will still need to be at your best; do you understand, Slut Tracy?"

Moaning in a sultry tone, wiggling her ass in anticipation, Tracy replies, "Oh please, Mother Harlot, please accept my apology and don't paddle my ass."

Tracy's playful begging only makes Jill hornier for her. She's actually almost dripping from the desire to grind her face into her slut's face and use her like the sex toy she is, but all in due time. Twirling her paddle, Jill saunters back to Tracy's awaiting ass. Slowly, Jill rubs the paddle over her slave's trembling ass cheeks.
