Because Big Sister Says So!

[PrincepsCyberius]

As Gus tightened his hold on Cathy's hips, and quickened the flicking of his tongue on her clitoris, her back arched, she clawed at the bedspread, and screamed. "Oh fucking CHRIST!!!"

Smiling around his tongue, Chris silently congratulated himself on his voracious reading habits. Planning to go to medical school, he had for years read every human anatomy and physiology book he could find. Meanwhile, since early adolescence, he had started regularly sneaking Penthouse magazines from his father's poorly hidden stack and not just looking at the pictorials, but also reading the articles. Combining what he learned in those two sources, he brought an expertise to pleasuring women that far outstripped his experience.

With Cathy still moaning and trembling, he started moving his tongue upon her clit as quickly as he could, alternating between lateral and vertical strokes. He considered slipping a fingertip into her anus, but decided he didn't want to lose his hold on her hips. Besides, he wanted to save something new for next time.

"Oh fucking CHRIST!!!" Cathy screamed, her back arched higher, and her fingernails tore several short rents into her parents' bedspread when Gus tightened his hold on her hips and quickened further the flicking of his tongue on her clitoris, alternating between lateral and vertical strokes.

"Fuck! Fuck!!! FUCK!!!! FUCK!!!!!!" she cried in rhythm with her thrusting hips and the waves of rapture crashing through her body from a third orgasm coming before the effects of the first two had waned.

"If that's how you do as a beginner," Casey sighed regarding the multiple orgasms Marie had just given her. "When you're experienced, you're going to kill me."

"Mmmmm..." Marie replied as she moved up to lay down next to Casey. "But what a way to go!"

Having paused in their own lovemaking, they could here their sister Cathy's impassioned screams from upstairs. "Oh fucking CHRIST!!! Fuck! Fuck!!! FUCK!!!! FUCK!!!!!!"

"It sounds like Gus might be about to kill Cathy that way," Casey giggled. "Do you want to go watch?"

“What a way to go!” Marie laughed when Casey joked her improving skills at cunnilingus could prove fatal.

Just then, Cathy’s cries carried distinctly from upstairs. “Oh fucking CHRIST!!! Fuck! Fuck!!! FUCK!!!! FUCK!!!!!!”

“It sounds like Gus might be about to kill Cathy that way,” Casey giggled. “Do you want to go watch?”

Marie’s eyes opened wide. Already surprised that it did bother her that her boyfriend made love to both of her sisters today, the idea of watching him do it intrigued, then excited, her. Her expression changed to concerned curiosity. “Are you sure Cathy won’t mind?”

 

[PrincepsCyberius]

"Fuck! Fuck!!! FUCK!!!!" Cathy cried in rhythm with her thrusting hips as her back arched higher and her fingernails tore several short rents into her parents' bedspread. "FUCK!!!!!!"

Maintaining a tight grip on her raised hips, Gus pressed his mouth forward, flattening his tongue into her clitoris with savage pressure as he moved it quickly left and right.

 

[KaseE]

Cathy's impassioned and vulgar moans from upstairs made Casey giggle. She winked at Marie. "Do you want to go watch?"

Marie’s eyes opened wide. "Are you sure Cathy won’t mind?"

"From the sound of things, I doubt that she'll notice," Casey predicted as she climbed out of bed and offered Marie her hand. "And even if she did, I know she won't mind. In fact, making you have to watch us have sex with Gus was all part of the plan."

The Best Defense



“Making you have to watch us have sex with Gus was all part of the plan,” Casey told Marie, referring to her and their oldest sister’s so far successful gambit to make Marie and her boyfriend Gus their sex slaves.

Marie frowned instinctively at the inherent cruelty of their intent, but quickly realized that given her reaction to her sisters’ seductive antics, especially Cathy’s sexual domination of her, she should expect and even accept it. Then the idea of seeing Gus making love to Cathy hit her and she discovered a voyeuristic excitement in it.

“Let’s go then,” she replied in a hoarse, sneering laugh and climbed from the bed. She did not bother to wait to see if Casey followed as she, still nude, ran up the stairs and followed the sound of Cathy’s moans and screams to their parents’ bedroom. Peeking around the door jamb she saw Gus laying on his stomach between Cathy’s legs, holding her hips off the mattress as he flicked his tongue on her clitoris. Cathy’s back arched so that the remainder of her weight rested on her shoulders. Her fingernails had torn into the bedspread. The expression of strained rapture on Cathy’s face ultimately caught Marie’s full attention.

I wonder if I look so beautiful in orgasm, Marie thought to herself as she found herself again panting with sexual desire.

 

[CCorteeze]

"Faaahhhh... UCK!" Cathy screamed as the pressure from Gus's oscillating tongue forced her into a fourth orgasm before the overwhelming ecstasy of the first three had waned. Her entire body, her back arched and her limbs outstretched, tensed and trembled, then collapsed. She began to savagely kick Gus away from between her legs, having become far too sensitive to touch.

 

[KaseE]

Casey heard Cathy's scram of ecstasy as she followed Marie up the hallway. "Faaahhhh... UCK!"

She got to the doorway of their parent's bedroom just in time to see Cathy's body, her back arched and her limbs outstretched, tense, tremble, then collapse. Apparently now too sensitive for any contact, Cathy began to savagely kick Gus away from between her legs.

"He did the same thing to me," Karen whispered her confession to Marie. "No wonder you love him! I hope you don't mind too much sharing him this way."

 

[PrincepsCyberius]

"Faaahhhh... UCK!" Cathy screamed in manifest ecstasy as Gus's tongue pressed into her clitoris with savage pressure and moved quickly left and right. He felt her body tense and tremble, then collapse. She immediately began kicking him savagely away from between her legs. He understood why. His girlfriend, Cathy's younger sister Marie, likewise could sometimes become too sensitive to touch right after orgasm.

Gus slid off the foot of the bed, grinning in pride at the height of pleasured passion to which he had driven Cathy. Then movement to his left caught his attention. He looked to find Marie, along with her younger sister Casey, watching from the hallway door.

The smile disappeared from his face. "Um, you know, Marie.... She left me with no choice."

Critical Review



Marie watched with lecherous fascination as her boyfriend Gus gave adept cunnilingus to her older sister, Cathy. An expression of strained rapture beautifully contorted Cathy’s face as her back arched so that most of her weight rested on her shoulders. Her fingernails had torn into the bedspread. She screamed in unchecked ecstacy. “Faaahhhh... UCK!

Her entire body tensed and trembled, with her back arched and her limbs outstretched, then collapsed. She began to savagely kick Gus away from between her legs. Marie understood why. She likewise would often become too sensitive to touch right after Gus gave her such a tremendous orgasm.

“He did the same thing to me,” Her younger sister Casey, who had joined her unnoticed in the doorway, whispered. “No wonder you love him! I hope you don't mind too much sharing him this way.”

To her surprise, Marie discovered that, quite to the contrary, watching Gus make love to Cathy not only turned her on, but filled her with pride to see the man who loved her so thoroughly control sexually her older and arrogant sister. It made her want to see more, and see him do the same to Casey. Before she could even begin to find the way to formulate this into an explanation, Gus had noticed them standing there. The pleased grin that eating Cathy to orgasm had left on his face disappeared. “Um, you know, Marie.... She left me with no choice.”

“I know,” Marie panted, then tried to clear her tight throat. “I just wish I’d gotten to see you fucking her!”

 

[CCorteeze]

"I just wish I’d gotten to see you fucking her!" Marie confessed to her boyfriend, Gus.

"Oh, don't worry!" Cathy panted as she lay sprawled face-up across her parents' bed, the last tremors of orgasm -- orgasm given her by her younger sister Marie's boyfriend, Gus -- faded from her trembling body. She inhaled deeply, then puffed out the breath. Rolling onto her right side, facing the door in which Marie, along with their younger sister Casey, both naked, stood, Cathy propped her head up on her hand and continued. "Meanwhile, let's show Gus what a 'lesbian slut' you've become. Eat Casey until she comes."

Love on Display



“Let’s show Gus what a ‘lesbian slut’ you’ve become,” Cathy told Marie. “Eat Casey until she comes.”

The idea of watching her boyfriend Gus make love to her sisters already had Marie horny. Now, the opportunity of having him watch her give cunnilingus to either of them — Marie instinctively knew how much this would turn him on — made her shiver with lust. She gently set her hands on Casey’s shoulders, backed her against the open door, and French kissed her deeply. Then, Marie got down on her knees and began to lick Casey’s womanhood with enthusiasm.

 

[KaseE]

Marie gently set her hands on Casey’s shoulders, backed her against the open door, and French kissed her deeply. Then, Marie got down on her knees and began to lick Casey’s womanhood with enthusiasm.

"Oh..." Casey sighed. "Yesss...."

She'd had some doubts about Cathy's plan to blackmail Marie and her boyfriend Gus into becoming their sex slaves. Now she reveled in it. Four seemed to work so much better than two for sex. Even if some lovers grew tired, the odds remained that at least one partner's lust would still match your own.

Although, as Marie's tongue brushed her clitoris, Casey wondered if anyone else could feel as lusty as she did today.

 

[EmpressJosephine]

Prurient Interest



“Oh...” Casey sighed as her older sister Marie licked her womanhood. “Yesss....”

Marie felt nearly as lusty as the object of her affectionate cunnilingus. She could only imagine what effect watching her do this to Casey had on her boyfriend Gus, but had little doubt he watched with interest. If observing her eat Casey affected him as much as it had excited her the see him eating her older sister Cathy, then she knew they had discovered a way to ensure their love life never grew boring.

To spice things up further, Marie reached up with her left hand to caress Casey’s right breast while using her right hand to stroke the back of Casey’s left thigh.

 

[PrincepsCyberius]

Gus watched with lascivious fascination as his girlfriend Marie gave oral sex to her younger sister Casey, playing with her ample breasts and caressing her thighs while she ate her. Despite his recent erotic escapades with Marie's older sister Cathy, Gus found himself already almost fully erect. He had to consciously restrain himself from stroking his stiff organ as he ogled the scene that before today he had known only in his most secret fantasies.

 

[EmpressJosephine]

From All Sides



Marie’s left hand continued to caress Casey’s right breast while Marie focused the tip of her tongue on Casey’s clitoris. This allowed room, after Marie’s right hand slid slowly and tantalizingly up the back of Casey’s left thigh, for Marie to slip her right index finger, then middle finger, far up Casey’s womanhood. She curled them forward to stimulate the base of Casey's clit while her tongue flicked over its exposed point.

 

[KaseE]

"Oh God..." Casey groaned as Marie revealed how much she had already learned by stimulating her clitoris from inside and out. Knowing that Marie's boyfriend watched as she gave Casey skilled oral sex excited Casey all the more. She could feel the rapturous pressure building inside her loins, and sighed. "I'm not going to last very long...."

 

[CCorteeze]

Cathy reclined on her parent's bed with Gus, her sister Marie's boyfriend, having blackmailed Marie and him into becoming her sex slaves. Together, they watched Marie giving oral sex to Casey, Cathy and Marie's younger sister, whom Gus and Marie had also agree to serve sexually. Cathy actually chuckled with joy. This could not have gone any better.

 

[EmpressJosephine]

Motivation



“Oh God...” Casey groaned as Marie curled her two fingers inside her sister forward to stimulate the base of Casey’s clitoris while she licked over its exposed point. “I’m not going to last very long....”

Hearing that, Marie happily ignored the cramping in her hand and jaw and increased the wiggling of her fingers and the flicking of her tongue to the fullest speed she could manage.

 

[PrincepsCyberius]

"Oh God..." Casey groaned, leaning back against the bedroom door, as her older sister Marie continued to give her vigorous oral sex. "I'm not going to last very long...."

Marie's boyfriend Gus watched from the foot of the bed, next to Marie and Casey's older sister Cathy, with whom he had just finished making love. Again feeling amorous from what they now watched the younger women doing, Gus reached over and started to gently caress Cathy's extended left calf and foot.

 

[KaseE]

"I'm not going to last very long," Casey warned, only to have Marie respond by wiggling her fingers against her G-spot and flicking her tongue on her clit even faster than before. True to her word, this added stimulation sent Casey over the edge. She began to come, screaming. "Oh, Jesus! FUCK! Fuck... Jesus! Oh...."

 

[EmpressJosephine]

Winding Down



“Oh, Jesus!” Casey cried out. Marie could feel Casey’s vagina pulsing around her fingers as she continued to scream “FUCK! Fuck... Jesus! Oh....”

Marie continued licking her clitoris while she slowly withdrew her still wriggling fingers.

 

[KaseE]

"Jesus!" Casey cried out in orgasm. "Oh....”

Marie continued licking Casey's clitoris while she slowly withdrew her still wriggling fingers from her vagina. Casey's knees gave way and, with her back still against the door. she began to slide down, both from exhaustion, and to prolong the contact between her womanhood and Marie's dexterous digits.

 

[EmpressJosephine]

Sliding Down



With her back still leaning against the door, Casey began to slide down. Marie stopped licking her clitoris, but kept her fingers gently caressing Casey’s womanhood until they came to rest on the floor. Then she carefully withdrew them, observing that Casey’s recent succession of intense orgasms had left her almost completely exhausted.
