Because Big Sister Says So!

"Oh, Marie..." Casey moaned as her sister continued licking her clitoris. "You're so good.... You're gonna make me come!"

Hearing this, Cathy increased the vibrator's power to full and slipped it all the way into Marie's vagina, angling it so that its "rabbit" appendage pressed firmly against Marie's clit.
 
Race to the Finish



“Oh, Marie...” Casey moaned as her sister increased the pace of her licking upon her clitoris. “You’re so good.... You’re gonna make me come!!!!”

Meanwhile, Marie groaned around her tongue when Cathy then raised the vibrator’s power to full and slipped it all the way into Marie’s vagina, angling it so that its “rabbit” appendage pressed firmly against Marie’s clit. She concentrated past the burgeoning ecstasy pulsing in her loins to maintain a quick and consistent rate of lapping at Casey’s womanhood. She wanted to make sure Casey came first.
 
Marie groaned around her tongue and increased the pace of flicking her tongue tip upon Casey’s clitoris.

"That's it!!!" Casey threw back her head and screamed at the ceiling as it seemed ten thousand fireworks burst overhead in time with the explosion of pleasure in her loins shooting up her spine and out into her arms and legs. "I'm coming! Oh... Oh God, I'm COMING!!!"

 
Tied at the End



“That's it!!!” Casey screamed as Marie continued licking her clitoris as fast as she could. “I’m coming! Oh... Oh God, I’m COMING!!!

The vibrator still buzzed at full power in Marie’s vagina, with Cathy angling its “rabbit” appendage so it pressed firmly against her clit. This stimulation by her older sister, together with the impassioned declaration of climax by the sister she loved best, ignited Marie’s own orgasm. In her desire to hold Casey, Marie strained against the cuffs holding her arms spread toward the corner of mattress. She tilted back her head, her chin now thrust against her sister’s pulsing womanhood, and cried out.

“Casey! I love you!!!”

 
"Oh, Marie..." Casey moaned as she knelt over the face of her bound sister, Gus's girlfriend Marie. "You're so good.... You're gonna make me come!"

Gus could not see what Marie did from where he sat on the floor next to the open hide-a-bed, but he could tell from Casey's reaction that Marie performed skillful cunnilingus upon her. He could see, however, as Marie's other sister, Cathy, sitting on the mattress next to them increased to full power the vibrator she held and slipped it all the way into Marie's vagina, angling it so that its "rabbit" appendage pressed firmly against Marie's clitoris. Marie groaned around her tongue as Casey threw back her head and screamed. "That's it!!! I'm coming! Oh... Oh God, I'm COMING!!!"

Gus unconsciously started stroking his rock-hard erection as he heard Marie's muffled reply. "Casey! I love you!!!"
 
"That's it!!!" Casey threw back her head and screamed at the ceiling as Marie continued licking her clitoris as fast as she could. It seemed as if ten thousand fireworks burst overhead in time with the explosion of pleasure in her loins. "I'm coming! Oh... Oh God, I'm COMING!!!"

Beneath her, Marie suddenly tilted her head back, thrusting her chin against Casey’s pulsing womanhood, and cried out in her own orgasm. "Casey! I love you!!!"

This brought Casey to the pinnacle of her climax, and she fell forward, catching herself on the couch back of the sleeper sofa, gasping "I love you, too, Marie.... I love you, too!"

 
"Casey!" Marie cried out in orgasm from where she lay, bound face up, with her younger sister sitting on her face. "I love you!!!"

"I love you, too, Marie," Casey gasped as she finished coming, falling forward to catch herself on the couch back of the sleeper sofa. "I love you, too!"

Her two younger sisters having reached mutual climax, Cathy carefully pulled the vibrator from Marie's vagina and laughed with joy. "Here we are! One big happy family!"
 
"Casey!" Marie cried out in orgasm from where she lay bound face up under her younger sister. "I love you!!!"

"I love you, too, Marie," Casey gasped as she finished coming by thrusting her womanhood upon Marie's chin. Then, falling forward to lean against the couch back of the sleeper sofa, Casey whispered. "I love you, too!"

"Here we are!" their older sister laughed happily from behind Casey. "One big happy family!"

Catching her breath, Casey carefully crawled forward to avoid hurting Marie, then turned around to face them both. Marie remained tied spread eagle upon the mattress, still panting from her climax, her face sodden with Karen's juices. Cathy knelt next to Marie's left thigh, still holding the "rabbit" vibrator she'd used to pleasure Marie even while Marie performed such amazing cunnilingus on Casey.

"That's right, Cathy," Casey finally replied to her comment. "And we love you, too, but I hope you'll understand if I say I need a little private time with Marie right now."

Casey tilted her head toward Marie's boyfriend Gus, sitting on the floor silently watching them.

She watched as Casey carefully crawled forward to avoid hurting Marie, then turned around to face them both and said, "That's right, Cathy, and we love you, too, but I hope you'll understand if I say I need a little private time with Marie right now."

Casey tilted her head toward Marie's nude boyfriend Gus, sitting on the floor silently watching them with his hand on his stiff penis.

"That's fine," Cathy smiled hungrily. She got off the bed. "I'm sure I can find something to keep me amused."

As she walked toward the stairs she tapped Gus on the shoulder and chuckled. "Come along, slave."

She headed up stairs with no doubt he would follow.
 
"I'm sure I can find something to keep me amused," Cathy said, climbing off the open hide-a-bed. As she walked toward the stairs she tapped Gus on the shoulder and chuckled. "Come along, slave."

Taking one last look back at Marie and Casey, wondering and a bit worried about what Karen might tell her sister, Gus knew he had no choice but to obey Cathy unless he wanted her to reveal her blackmail photos to Marie's parents. Besides, in truth, he looked forward to whatever sexual adventure Cathy might have in store for him. With his full erection leading him, he followed Cathy up the stairs.


 
"I know you heard me say that I love Gus," Casey said as she released Marie's left wrist from the shackles in which Cathy had left her. She then moved to the right and unbuckled it. "But I've loved you all my life, and never want to hurt you. So I thought we ought to talk about it."


 
Discovering Freedom



Marie had grown so accustomed to being bound, and all the pleasure she’d experienced while in that state, that it felt a bit odd at first as Casey freed her wrists.

“But I’ve loved you all my life,” Casey said in counterpoint to her earlier confessions of love for Marie’s boyfriend, Gus. “And never want to hurt you. So I thought we ought to talk about it.”

Marie sat up, but instantly felt dizzy and dropped back onto the mattress. She understood her sister’s concern, but after the love they had just shared, the idea of sharing Gus’s love seemed almost natural.

“It’s alright, Casey,” Marie replied, her voice a bit hoarse from the rough sex she’d just finished with her sisters. “I love you and... and I think I understand.”

 
As he reached the top of the stairs, Gus heard Casey speaking to Marie in the basement below. "I know you heard me say that I love Gus, but I've loved you all my life, and never want to hurt you. So I thought we ought to talk about it."

"It's alright, Casey," Marie replied, her voice sounding a bit hoarse. "I love you and... and I think I understand."

Gus smiled hearing this. Knowing Marie had, at least, come to terms with their role as Cathy and Casey's blackmailed sex slaves would make the rest of this week even far more enjoyable than he had found it already.

Cathy reached the top of the stairs, crossed the family room, and took a seat in the chair her father traditionally used when home. She had just settled into it, her arms resting on each side, her knees together and ankles crossed, when Gus emerged through the door to the basement. Cathy could hear Casey and Marie's voices rising up behind him.

"Shut that door," she ordered with a cold grin, then lifted and extended her left left leg, toes pointing straight at Gus. "And worship me."
 
"It's alright, Casey," Marie replied. Her voice, not surprisingly given what Cathy and Casey had put her through, had become a bit hoarse. "I love you and... and I think I understand."

"Oh good! I..." Casey decided to proceed carefully, given the emotions involved. Marie, even with her arms free, remained laying down. Casey moved to the foot of the bed to unshackle her sister's ankles as she explored her feelings. "What is it you 'understand'?"


 
Describing Love



“It’s alright, Casey,” Marie replied, her voice a bit hoarse from the rough sex she’d just finished with her sisters. “I love you and... and I think I understand.”

“Oh good! I...” Casey paused as she moved to the foot of the bed to unshackle Marie’s ankles. “What is it you ‘understand’?”

“It’s... it’s about love,” Marie spoke slowly as she put a complex realization into words for the first time. “It came to me while I was making love to you. With Cathy.... Well, with Cathy at first it was because I had to, and then because... um.... You know... she made me need it so bad. With you, I really wanted to make love to you, because I love you so much. I realized that giving someone that kind of pleasure is a way... a very special way to show how much you love them. Don’t get me wrong, I love Cathy, too. It’s just that you and I have always been so close. That’s why this all came to me while I was making love to you. I know sisters aren’t supposed to make love, but why not? What harm can it do? It’s such a perfect way to show love.”

"Shut that door," Cathy spoke in a commanding voice not entirely consistent with her hungry grin. She then lifted and extended her left left leg, toes pointing straight at Gus. "And worship me."

It surprised Gus how much that simple statement turned him on. He never thought of himself as sexually submissive, rather quite the opposite. In this case, however, having Marie's beautiful older sister sitting across the room in that regal manor, and demanding such total sexual attention as her command implied, brought his erection back to its full size and vigor. He suddenly yearned for Cathy, and knowing he could only have her on her terms made that desire all the more compelling.

His eyes transfixed on her proffered foot, he reached behind himself, found the knob, and shut the basement door. Then he got down on his hands and knees and crawled reverentially across the room to her. He whispered hoarsely: "Yes, Mistress."

 
"Yes, Mistress," Gus said simply as he he got down on his hands and knees. Cathy had seen how her command to worship her had stiffened his beautiful cock. Her own loins began to ache with need as he crawled reverentially across the room toward her extended left foot.
 
“It’s... it’s about love,” Marie started slowly. “It came to me while I was making love to you. With Cathy.... Well, with Cathy at first it was because I had to, and then because... um.... You know... she made me need it so bad. With you, I really wanted to make love to you, because I love you so much. I realized that giving someone that kind of pleasure is a way... a very special way to show how much you love them. Don’t get me wrong, I love Cathy, too. It’s just that you and I have always been so close. That’s why this all came to me while I was making love to you. I know sisters aren’t supposed to make love, but why not? What harm can it do? It’s such a perfect way to show love.”

Casey had intended to discuss the situation with Gus, but realized Marie had greater concerns about their incest, an issue Casey had come to terms with months earlier, after Cathy first seduced her. She had herself come to the same conclusions silently that Marie had just expressed so elequently. Casey took a deep breath and returned to her original topic.

“So how does Gus fit into all of this? How do you feel about me being in love with him and... and making love with him?”
 
Gus didn't have an actual foot fetish, but a dainty and nicely formed female foot could turn him on as readily as shapely legs, a tight derriere, a slim waist, pert breasts, or a pretty face. Cathy, indeed, had all of these features. At the moment, however, she extended just her left foot for him to worship. As he crawled up to it on hands and knees, he spoke.

"I shall worship you, Mistress, starting with your lovely foot." Kneeling, with his erection now angled up over his lap, he took her foot in his hands and bent down to gently kiss her instep.

 
Sharing Love



“It’s just that you and I have always been so close,” Marie concluded her thoughts about the intimacy she and her sisters had just shared. “That’s why this all came to me while I was making love to you. I know sisters aren’t supposed to make love, but why not? What harm can it do? It’s such a perfect way to show love.”

Casey took a deep breath. “So how does Gus fit into all of this? How do you feel about me being in love with him and... and making love with him?”

“Well,” Marie sat up and faced her sister, looking her tenderly in her lovely hazel eyes. “That’s all part of the same thing, isn’t it? It’s like, we’re all family. You’ve been calling him your ‘future brother-in-law’ for a while now. If it makes sense that you and I show our love as sisters the way we just did, then doesn’t it make as much sense that we share all that together with someone you love, at least like a brother and... now I guess, even more than that. Remember that lesson Father Roetzer sometimes gave about love being like a candle flame. As you light another candle, the original doesn’t diminish, you just get more flame. No matter how many candles you light that way, each candles light only adds to the whole, without lessening any of the others. I guess he was more right than he probably realized. That’s how I look at our love, and how we now share it for Gus, and Cathy too. Your and Gus’s love doesn’t diminish his love for me or mine for him. It just adds to the love we all share.”

 
"I shall worship you, Mistress," Gus proclaimed, his voice husky with desire. "Starting with your lovely foot."

Kneeling, with his erection now angled up over his lap, he took Cathy's left foot in his hands and bent down to gently kiss her instep. The sensation of his strong fingers along with his tender lips on her sensitive foot, combined with the knowledge that she would have this handsome, confident, and previously forbidden man as her slave and lover for the next week, overwhelmed her for an instant. Despite herself, Cathy groaned audibly.
 
Cathy groaned audibly as Gus gently kissed her instep. This only turned him on more, inspiring him to run the flat of his tongue up the arch of her sole, then firmly kiss the tip of each of her toes, returning finally to the big toe to take it gently between his teeth and lick it lightly.



 
"Your and Gus's love doesn't diminish his love for me or mine for him," Marie explained. "It just adds to the love we all share."

"That's... That's...." Casey swallowed. "That so beautiful!"

With tears of joyous love forming in her eyes, Casey leaned forward and kissed her sister with deep passion.



 
Tenderness



“That’s... That’s....” Casey swallowed. “That’s so beautiful!”

With tears of joyous love forming in her eyes, she leaned forward and kissed Marie with a deep passion that her sister immediately reciprocated. As they kissed, Marie’s right hand found Casey’s full, left breast and caressed it softly.

“I’ve always admired your breasts,” Marie said when they paused their kiss to catch their breaths, although both already panted with shared lust. “It never even occurred to me, however, how nice it would be to do this.”

Pushing her sister gently back on the bed, Marie bent down and took Casey’s stiffened right nipple between her lips and licked its tip.
