Because Big Sister Says So!

Selfish



“You have Gus,” Cathy said simply. Oddly, even though most people would consider Cathy and Casey prettier than her, only Marie had ever kept a steady boyfriend and found love.

“But,” Cathy continued. “If you love your sisters, then it’s time to share!”

“No freaking way!” Marie growled back, then turned to Gus, looking for support.



 


“You have Gus,” Cathy said. “But, if you love your sisters, then it’s time to share!”

“No freaking way!” Marie growled back, then turned to Gus, looking for support.

Being careful to keep his face from betraying any emotion, he simply nodded. "Of course. We're adults after all. What makes you think you can blackmail us by showing we make love?"


 
Suggestions

"We're adults, after all," Gus pointed out about Marie and himself. "What makes you think you can blackmail us by showing we make love?"

"Would you really want my parents, especially my father, to see those photos?" Cathy asked. "I know how much you enjoy your good relationship with them, how would you like to become persona non grata around here?"

She then turned to Marie. "How about you? Do you want to have dad look at you like you know he would if he saw those pictures, with you naked on top of Gus, fucking him like a whore and wailing like a slut in heat?"
 
Cornered



“Do you want to have dad look at you like you know he would if he saw those pictures,” Cathy taunted Marie. “With you naked on top of Gus, fucking him like a whore and wailing like a slut in heat?”

Marie’s hands balled so tightly into fists that her fingernails dug into her palms. Her brow furrowed with frustration and anger as tears seeped from her eyes. She spun around, her back to her sisters, and snarled into the now empty recreation room where, five minutes earlier, they’d surreptitiously photographed her making love with her boyfriend.

“What...,” she growled. “What would we have to do?”




 
A Reasonable Offer

"What would we have to do?" Marie asked, her back turned to her sisters.

"It's simple," Cathy replied, not feeling as generous as she tried to sound. "You'd just have to make love with us, when and how we wanted. Given how much you obviously like sex, you'll probably even enjoy it!"
 
Seeking Counsel



“You’d just have to make love with us, when and how we wanted,” Cathy explained what she meant by Marie and Gus becoming her and Casey’s sex slaves. “Given how much you obviously like sex, you’ll probably even enjoy it!”

Marie blushed, knowing what the photos must show, her face contorted with ecstasy as she rode her boyfriend. She softly touched Gus’s upper left arm. “What do you think we should do?”




 

“What do you think we should do?” Marie asked Gus about Cathy's ultimatum as she gently touched his arm. The idea of becoming a sex toy for her two beautiful sisters did not bother him as much as it clearly bothered her. He simply did not want to appear too eager.

“Do we have any choice?” he posed noncommittally. Keeping his face frozen, he finished with a truth. “I sure would not want to have to face your mom and dad if they ever saw those pictures!”




 
Capitulation



“What do you think we should do?” Marie asked Gus about Cathy’s ultimatum as she gently touched his arm.

“Do we have any choice?” he replied. “I sure would not want to have to face your mom and dad if they ever saw those pictures!”

Marie nodded. She could not imagine bearing the shame and humiliation that would come with her parents seeing the photographs. Perhaps Gus’s proximity helped, or maybe she’d taken to heart Cathy’s earlier suggestion that she might “even enjoy it,” but she had to admit that compared with what her parents would say about evidence of her ordinary lovemaking with Gus, the idea of a sexual adventure had her suddenly — and unexpectedly — slightly turned on. That realization, in turn, shocked and embarrassed her.

“Okay,” she relented, staring at the floor, unable to look her sisters, or even Gus, in the eyes. “Okay. What do you want us to do?”





 
Barely Started

“Okay,” Marie finally accepted the inevitable and agreed that she and her boyfriend Gus should become her sisters' sex slaves. Staring at the floor, she spoke softly. “Okay. What do you want us to do?”

“As for you,” her older sister Cathy replied. “I rather liked when you were running around naked upstairs so, to begin with, take off that robe and don't put anything else on without my permission.”
 
Optimist



“I rather liked when you were running around naked upstairs,” Cathy premised her first command for Marie. “So, to begin with, take off that robe and don’t put anything else on without my permission.”

Marie sighed. This made sense. For some reason, Cathy wanted to humiliate her.

Even as she removed the robe and tossed it onto the couch, Marie felt a secret triumph. Why should she care about being nude in front of these three people, two sisters with whom she’d grown up, and her one and only lover. If Cathy had just this sort of thing in mind, it shouldn’t be that bad.





 
Surprises

Cathy raised an eyebrow seeing how readily Marie stripped out of her robe and stood there, almost defiantly, in front of them.

"Very good," Cathy said. A somewhat experienced dominatrix, she knew praise acted ultimately as a far more effective tool for obedience than punishment. "Now you must kneel. Unless a command I give you requires otherwise, you shall always kneel in my presence.

"That goes for you, too, Gus," she told Marie's boyfriend. Then she glanced and nodded at Casey, granting her silent permission to join in.
 
Opportunist



Marie knelt. She had read Fifty Shades of Grey, but not yet found a way to tell Gus about her desires based on that book. If nothing else, this could open that topic between them.




 
Casey saw Cathy's glance, signalling her to pronounce what would happen next. Instead, she stepped closer and whispered in Cathy's ear.

"I know I said I wanted the first time to be in front of Marie, but I've changed my mind. Do you think I could have him for myself a while?"

 
Split the Party

"I know I said I wanted the first time to be in front of Marie," Casey whispered in Cathy's ear. "But I've changed my mind. Do you think I could have him for myself a while?"

"That suits me just fine," Cathy replied, neither bothering to lower her voice, nor to hide her lascivious glance toward their sister Marie kneeling before them.
 
"I know I said I wanted the first time to be in front of Marie," Casey whispered in Cathy's ear. "But I've changed my mind. Do you think I could have him for myself a while?"

"That suits me just fine," Cathy replied out loud.

"Okay, then," Casey said with more confidence than she felt, although she could feel a flush rising on her cheeks from a combination of embarrassment and sexual excitement. "Gus is coming upstairs with me."


 

“That goes for you, too, Gus,” Cathy said regarding her rule that Marie should always kneel in her presence. As he got down on his knees, he saw Casey whispering something to Cathy, but could not make it out. Cathy, however, replied out loud. “That suits me just fine.”

“Okay, then,” Casey said. “Gus is coming upstairs with me.”

Shocked, Gus looked at her, saw she meant it, then turned to see Marie’s reaction.



 
Nipped in the Bud

“Gus is coming upstairs with me,” Casey announced.

Gus looked at her, obviously shocked, then turned to Marie, who looked like she was about to say something.

"Keep quiet!" Cathy commanded. "Remember, any objections and those photos go to Mom and Dad."

Casey smiled, crooked a finger at Gus, and said, "Come with me, my Dear."

She turned and led the way upstairs.

Casey smiled, crooked a finger at Gus, and said, "Come with me, my Dear."

She turned and led the way upstairs. Gus got on his feet and, with an embarrassed and apologetic look at Marie, followed Casey up the basement steps.



 
Realization



Marie almost couldn’t stand it. Only the fear of — not so much what he would say — but how her father would look at her if he ever saw the pictures of her lascivious lovemaking with her boyfriend Gus, kept her from objecting as Gus disappeared upstairs with her younger sister Casey.

Now alone with her older sister Cathy, Marie, still on her knees, looked up into her cold but hungry blue eyes. With Gus gone, the full implications of submitting as a sex slave to two women fully occurred to Marie for the first time. She started to feel a bit sick to her stomach.



 

Casey felt a great deal of relief when Gus followed her upstairs. She didn't know if she had the heart to go through with this if he had objected. Now, she hoped just being together, alone, he would come to know how she felt and maybe show that he felt the same.

He and Marie had started dating almost four years earlier, and Gus quickly became a regular guest at their house. He'd, at first, seemed like the brother she had never had. Then, one night, she had a sexual dream about him. She saw him differently afterward. Soon, she realized that she loved him.

She sometimes suspected he might feel more than fraternal affection for her as well. His hugs often lingered a bit longer than seemed appropriate for a mere friend. Sometime when they spoke, he looked so deeply into her eyes she felt that he sought to touch her soul.

At the top of the stairs, she turned left and slowly walked toward the other end of the house with Chris following silently, a few paces behind. At the end of the hallway, she entered her parents' master bedroom. It made sense to do this here. It had the largest bed. Besides, even if it turned out she could not make Gus love her, she could have fun playing house with him for the next few days.
 

Gus got on his feet and, with an embarrassed and apologetic look at Marie, followed Casey up the basement steps. The expression on his face showed his true feeling, but not entirely due to the motivations he hoped Marie assumed. He felt ashamed regarding this situation because it looked as if it would fulfill a fantasy he'd always kept deeply hidden from Marie.

He loved Marie, he truly did, but he'd had fantasies about sex with her sisters for almost as long as he'd dated her. He'd imagine making love with Casey most of all, but never expected it to manifest anywhere but his dreams. Now, as she led him into the master bedroom after declaring she loved him and wanting to spend time with him alone, he suspected they would soon come true. The guilt he felt about soon cheating on Marie, theoretically under duress but in reality with enthusiasm, lacked sufficient potency to suppress the erection growing inside his jeans.





 
Raw Recruit

After Casey and Gus had disappeared upstairs, Cathy smiled down at Marie kneeling before her.

"We should let then have their privacy," Cathy said with intentional cruelty. She had read that the purposes of military boot camps included breaking the spirit of recruits in order to rebuild them into warriors. Cathy had similar intentions to reshape Marie, albeit as a lover, not a fighter.

"We'll stay down here," she continued and pointed to the sofa in the rec-room. "You may rise in order to go open up the hide-a-bed."
 

Karen turned to face Gus as he entered her parents' master bedroom.

"Don't kneel," she told him. "That's Cathy's thing. I may want you to kneel to me, too, later, but not now. Now...."

She took a step closer to him and set her right hand gently on his left elbow. She gazed deeply into his eyes. "I suppose you heard what I told Marie, that I... I love you. Tell me, is there any chance you love me, too? I've thought I've seen it in your eyes sometimes. Do you love me, Gus, or at least... or at least like me enough to want to be my lover?"



 
The Business at Hand



Marie visibly winced when Cathy said, “We should let them have their privacy.”

She had always considered Casey much prettier than herself, and wondered if Gus thought so, too. Now Karen, who had admitted earlier that she loved him, had him all to herself, with him having promised to do whatever she ordered. Marie tried not to think of what might happen.

“We'll stay down here,” Cathy added. “You may rise in order to go open up the hide-a-bed.”

Marie automatically got up from her knees, her gaze following her sister’s pointing finger to the sleeper-sofa in the rec-room. Marie went to it, piled its three cushions to the far side, and began to unfold the mattress. This turned her thoughts to her own immediate situation.

Although as she worked on the hide-a-bed her back faced her, Marie spoke to Cathy. “I never realized that you’re a... um.... That you like girls.”
