Because Big Sister Says So!

[EmpressJosephine]

The Nature of Their Love



“I love you girls!” Cathy screamed at the pinnacle of her second orgasm.

“We love you, Mistress,” Casey replied as she placed her hand on the back of Marie’s head to ensure she continued licking Cathy’s clitoris, which Marie did with enthusiasm.

That exchange said it all, Marie realized. This relationship — she and Casey as Cathy’s devoted and adoring slaves — was far more about love than sex. Cathy had always looked after them and guided them, and they had always loved and admired her for it. Their enslavement simply brought this to its full and natural actualization. The sex simply acted as an exceptionally pleasant expression of the nature of their love.

Marie moaned around her tongue at this thought. She needed to come so badly that she thought she might cry. At the same time, however, she fully trusted that whatever purpose Cathy had for depriving her now would prove well worth it in the end.

 

[CCorteeze]

Casey's avowal of love, together with Marie's continued clitoral cunnilingus, quickly drove Cathy to a third and even more intense orgasm. She broke her kiss with Casey as her spine arched and her head snapped back. She did not scream this time, and only a high pitched hiss escaped her tightened throat, followed by a drawn out curse as her ecstasy started to subside.

"Fu--- uuh -- uh-- u-- uck...."

Suddenly, it all overwhelmed her senses and she could no longer take the intense sensations of physical contact. She shoved Casey away with her right hand while her knees bent and feet drew up. She planted these on Marie's shoulders and kicked her away. It then took Cathy a moment to catch her breath. Finally, her eyes blinked open.

"That was excellent, Lesbian Slut," she told Marie, using her slave name. "You have become such a skilled pussy eater, I'm wondering if I should ever let you return to Gus. Straight sex seems like a waste of talent in your case."

She sighed contentedly, then appeared to remember something. She turned her head to Casey. "Did you take care of the recipe ingredients like I said?"

 

[KaseE]

Casey stood next to Cathy's chair smiling brightly like a little girl receiving praise. Nothing pleased her more than giving orgasms to her lovers, especially her older sisters.

Cathy turned to her and asked: "Did you take care of the recipe ingredients like I said?"

"Yes, Mistress," Casey grinned wider. "And the recipe looks really yummy!"

 

[CCorteeze]

"You've done an excellent job serving me while also keeping my new slaves in line," Cathy told Casey. Filled with energy following her orgasm, she shot up out of her seat, walked over, and French kissed Casey. Then she stepped back and smiled at her. "You get a reward. Get undressed and take my place in the chair."

She turned around and gently kicked Marie, who remained seated on the floor. "Lesbian Slut, I want you to give Casey as good an orgasm as you just gave me. You still don't get to come, but I want you to make Casey come so hard that her screams shake the windows. You got that?"

She punctuated her question with another slightly harder kick. Not waiting for an answer, she walked into the kitchen from where, over the breakfast bar, she could watch her sisters make love.

 

[KaseE]

Casey herself had suffered Cathy's orgasm denial strategies in the past, sometimes for days on end, so she sympathized and empathized with Marie. That, however, did not cause her to hesitate in claiming her prize. She settled onto the chair with her butt near the front of the cushion and spread her legs.

"Sorry, Sweetie," she said to Marie. "I know how you're suffering, but I really need this."

 

[EmpressJosephine]

Irresistible



“I know how you’re suffering,” Casey admitted as she sat in the chair in front of Marie, thrust her hips forward, and spread her legs. “But I really need this.”

“Oh, God....” Marie mewled with increasing lust, her gaze drawn mercilessly to the strawberry blonde curls and pink folds of her sister’s womanhood, already glistening with anticipation of the caress of Marie’s tongue.

She did not disappoint. Crawling forward, the thought to tease Casey crossed Marie’s mind, but she could not wait to taste and pleasure her. She wrapped her arms around Casey’s thighs and held her in place tightly while she immediately began to suck, nibble, and lick her stiff clitoris.

 

[KaseE]

Casey's sigh of anticipation as Marie's arms slipped under and wrapped around her thighs rose into a shrill gasp when, without hesitation or preliminaries, Marie began licking and sucking her clitoris.

"God yes, Marie..." Casey's voice cracked. "I need it so much!"

 

[CCorteeze]

"I need it so much!" Casey screeched.

Cathy looked up across the breakfast bar and family room to where Marie knelt between Casey's legs giving her oral sex. Cathy smiled. She had turned her younger sisters into perfect Sapphic sex slaves.

Then she returned to preparing dinner.

 

[KaseE]

"Oh God, Marie!" It amazed Casey how quickly her sister's tongue had already driven her toward climax. "I'm about to come!!!"

 

[EmpressJosephine]

Rush to Glory



Marie smiled around her extended tongue when Casey screamed of her impending orgasm. She easily slipped two fingers inside of Casey. Then she sucked her sister’s stiff clitoris into her mouth and gently clamped her teeth upon it as she flicked its hardened nub with the tip of her tongue.

 

[KaseE]

"Yep!!!" Casey squeaked sharply as orgasm tightened every muscle in her trembling body. "I'm coming...."

 

[EmpressJosephine]

Won’t Back Down



Marie found she took great joy and satisfaction from giving the ultimate pleasure to her sisters, especially Casey. Now, with Cathy forbidding her to have an orgasm, Marie had to find happiness elsewhere. So, when Casey’s hips started to buck and she shrieked in climax, Marie did not relent. She wrapped her arms tightly around her sister’s thighs and continued to flick her tongue tip upon Casey’s stiff clitoris.

 

[KaseE]

"No! Ohh... Oh no...." Casey protested as Marie's continued clitoral cunnilingus overwhelmed her already overstimulated senses. Then, as the last vestiges of her first orgasm faded, her pleasure immediately began to build toward a second, even fuller climax. "Yes... Okay! Keep going.... YES!"

 

[EmpressJosephine]

A Bold Experiment



Casey’s surrender to continued cunnilingus encouraged Marie to endeavor to make her sister’s next orgasm better than the earlier one from which she still trembled. She decided to try something Gus did to her sometimes, even though she still hadn’t decided if she liked it. Slipping her hands under Casey’s tight buttocks, she squeezed gently. Then, continuing to lick her clitoris the whole time, she slid her right hand slowly down and toward the center of Casey’s bottom, until her pinkie found her anus, already slick from the juices flowing from Casey’s womanhood. This made it easier for Marie to insert her finger just a bit into Casey’s behind.

 

[KaseE]

"Oh God..." Casey moaned when she felt the tip of Marie's finger pressing into her anus. Cathy had already trained her to fully appreciate anal penetration, often with toys much thicker than a feminine finger. It felt especially wonderful paired with Marie's tongue upon her clitoris.

"My God," Casey pleaded. "I need more of that!"

 

[EmpressJosephine]

Hypothesis Supported



“I need more of that!” Casey moaned when Marie pressed just the tip of her finger into Casey’s anus. Even as she continued to lick Casey’s clitoris, Marie raised her eyebrows at this eager plea. She immediately complied, inserting her pinkie as far as the first knuckle behind the fingernail.

 

[KaseE]

"More..." Casey repeated when Marie's slick finger slid into her anus up to the first knuckle behind the fingernail. Cathy had already trained her to fully appreciate anal penetration, and it felt especially wonderful paired with Marie's ongoing licking of her clitoris.

"Deeper!" Casey pleaded. "All the way in...."

 

[EmpressJosephine]

Expectations



“All the way in!” Casey urged after Marie slipped her pinkie into Casey anus, as far as to the first knuckle behind the fingernail. Marie marveled at this discovery of her sister’s anal desire. It shocked her almost as much as Casey and Cathy’s incestuous lesbianism, in which she herself now eagerly participated.

Marie slid her tongue down from Casey’s clitoris to where her finger disappeared into her butt. She used her saliva and Casey’s juices to get the exposed part of her finger as wet and slippery as she could. Then she slid its whole length slowly into her while returning to licking her clit.

A few times, when her boyfriend Gus had given Marie cunnilingus, he had played with her bung hole, though never inserting his finger beyond its tip, due to her ambiguous response. Now, consistent with all the other new experiences Cathy and Casey had shared with her, Marie had no doubt she would explore anal at least to the degree she now gave it to Casey. Experience with her sisters now had her expecting to like it.

 

[KaseE]

"God, YES!" Casey squealed when Marie slid her entire slick pinkie into her anus while she resumed licking her clitoris. After only a few seconds of this, Casey's back arched and her limbs stiffened as her whole body shuddered with paralyzing orgasm.

"My God, Marie!" she managed to gasp. "I love you...."

 

[CCorteeze]

Cathy smiled, watching with rapt attention and full approval as Marie brought their younger sister Casey to orgasm by oral sex enhanced with anal play. She knew from the moment she hatched this blackmail scheme that she could turn Marie into a bisexual love slave, just as she had with Casey earlier that year. She had sensed Marie's raw sexuality, which had grown noticeably ever since she had lost her virginity with Gus over a year before. The enthusiasm with which Marie accepted her place as a Sapphic submissive, however, pleasantly surprised Cathy. It made her all the more excited when considering her plan for this evening by which she intended to ensure Marie would always, even when she returned to Gus, live up to her current nickname of "Lesbian Slut."

 

[EmpressJosephine]

Persistence



It took only a moment for Casey to climax after Marie slipped her entire pinky up Casey’s anus while continuing to flick her tongue on her clitoris.

“My God, Marie!” Casey gasped in the continuing throes of her orgasm. “I love you....”

Marie continued the cunnilingus as she wriggled her finger inside Casey’s butt, wondering if this would prolong her sister’s ecstasy.

 

[KaseE]

"Uh..." Already panting in orgasm, Casey inhaled sharply when Marie wiggled her finger deep inside her anus. Marie's tongue flicking on her clitoris did not prolong Casey's orgasm. Instead, it caused her to come again, surpassing and building upon her earlier climax. She gasped. "Huh... huh... h-huh!"

Then she screamed. "Oh! FUCK! It's... it's.... oh... my... God!"

 

[CCorteeze]

Cathy well recognized the sounds of Casey's multiple orgasms. She enjoyed this chance to observe them as a spectator, rather than their inducement. A lean runner and dancer, Casey's smooth muscles rippled visibly as her body convulsed in waves of pure ecstacy.

She waited until Casey's countless climaxes culminated. She suspected Marie might plan to continue pleasing her sister, and Cathy herself had conditioned Casey to handle such overstimulation, so she interrupted them.

"That's enough for now. You two get cleaned up and get dressed. I want you to wear only the garter belts, stockings, and waitress uniforms we bought today. Make the stockings the drab beige ones, and black pumps. And both of you remember, Lesbian Slut still isn't allowed to come!"

 

[EmpressJosephine]

Lost in Need



Marie rested on the floor, her legs curled beneath her, her face reclined against the inside of Casey’s left thigh. Her jaw and tongue had grown sore from giving her sister such prolonged cunnilingus, and she panted. Her heavy breathing, however, came not from the rigors of performing oral sex, but rather from how horny doing it had made her.

Cathy repeated her prohibition on Marie having an orgasm herself. She did not know how much longer she could comply with that directive. She felt that much more denial of her ever heightening need might make her crazy.

None the less, she had to try to obey. Cathy still had those incriminating photos of her and Gus making love. Just as importantly, if not more so, she would feel shame if she disappointed Cathy because she could not control her urges.

With a determined sigh, Marie stood up and offered her hand to Casey to help her from the chair where she reclined, recovering from her own series of glorious orgasms, the like of which Marie so desperately needed.

 

[KaseE]

Casey accepted gratefully Marie's help up from the chair. Her legs still felt wobbly after the string of orgasms her sister's already expert cunnilingus had just provided. She held onto Marie's hand as they walked to the other end of the house, containing the baths and bedrooms.

"Mistress is really going all out on your orgasm denial," Casey finally commented to Marie as they reached the main bathroom. "I'm not sure whether to pity you or envy you. I can imagine the Hell you're going through, with all the sex this afternoon, but you not getting to come. On the other hand, I bet Mistress has something special planned that this is just the preparation for."

She kissed Marie deeply, keeping her hands away from her erogenous areas, then concluded. "You shower, first, Hon... but remember not to make yourself come, or I'll have to tell Mistress."
