With a flick of her wrist, Elana activated a remote. The chairs the sisters were tied to slowly began to rise, moving from the reclined position to an upright one. The sisters all let out a relieved sigh as they found themselves sitting up. The cum shifted direction and began running the opposite way down their bodies. Tle floor was a mess of slop.
Elana paced around them. “You see, I’ve designed this contest to test not just your physical endurance, but also your mental fortitude, your emotional resilience, and your sexual prowess. I want to see you break, but I also want to see you grow. I want to see you embrace your desires, your darkness, and come out stronger on the other side.” She stopped in front of Lucy and Desiree, her gaze lingering on the cum that still stained their chins. “You two, for instance,” she said, a smirk playing on Elana reached out, her fingers wrapping around the base of Lucy’s dildo. “This,” she said, giving it a slight squeeze, “has served its purpose.” With a quick twist and pull, she removed it from Lucy’s body, eliciting a small gasp from the futanari. Elana held it up, examining it with a satisfied nod. “Completely soaked, isn’t it, Lucy?”
Lucy, still trying to process her earlier actions and Elana’s words, could only nod mutely, her eyes following the dildo as Elana turned her attention to Desiree. Elana’s smirk deepened as she brought the glistening toy close to Desiree’s asshole. “And now, Desiree, it’s your turn to feel the pleasure of your sister’s dildo.”
Desiree’s eyes widened, a mix of shock and arousal in her gaze. “Elana, stop! No!” she squeaked.
“Just giving you a taste of medicine, dear,” Elana replied, her voice laced with amusement. She pressed the tip of the dildo against Desiree’s asshole, slowly pushing it in. Desiree Elana, with a wicked grin, thrust the dildo into Desiree with one swift motion. Desiree’s eyes widened in surprise and pleasure, a moan escaping her lips as her body stretched to accommodate the toy. Elana held it there, twisting it slightly, drawing out another yell from Desiree.
“Elana, please,” Desiree panted, her hips squirming, “Don’t hurt me with Lucy watching.”
Elana chuckled, “Oh, Desiree, you misunderstand. This is just the beginning.” She turned her attention to Lucy. “And now, Lucy, it’s time for you to make it up to your sister.”
Lucy, still reeling from her earlier actions, looked at Elana with confusion. “What do you mean?”
Elana smiled, a smile full of dangerous intent. “I mean, you’re going to ride your sister, just like you wanted to before. And you are going to make her cum, Lucy. You’re going to make her cum inside you and fill you with sisterly love.” Lucy’s eyes widened, realization dawning on her. “Now, Lucy,” Elana continued firmly, “you’re going to straddle Desiree, facing away. I want you to ride her, slowly and gently. Make her feel every inch of your tight hole.” Elana untied Lucy’s legs from the chair. She grabbed Lucy by the waist, lifting her up so her bound hands lifted over the back of the chair, and positioned her on Desiree’s lap. Elana had great strength and Lucy’s light weight was effortless for her to lift. Desiree’s heart skipped a beat as she felt Lucy’s pussy lips brush against her erect cock. Elana secured Lucy’s legs to Desiree’s with the same bonds that had tied Lucy to the chair.
Lucy’s face was a mix of shock and determination as she watched Desiree’s penis guided to her entrance. She was already wet, her body responding to the earlier stimulation and the new, unexpected turn of events. Elana moved Lucy forward to insert Desiree’s hardening member, and then pushed her back. Lucy sank down, inch by inch, her eyes locked with Elana’s, who stared unflinchingly back at her.
Desiree let out a defeated moan as she felt Lucy’s tightness envelop her. Lucy’s short vaginal canal couldn’t accomodate much of Desiree’s dick, but Lucy was so small that her body squeezed the dick that entered tightly. Lucy’s eyes fluttered closed for a moment, a soft sigh escaping her lips. Elana, satisfied with their positioning, grabbed a set of restraints and secured Lucy’s wrists to Desiree’s ankles, ensuring she was firmly in place. Desiree made the mistake of opening her eyes and was struck with the sight of Lucy’s tiny puckered butthole. It was a cute pale pink. With Lucy bent forward, Desiree couldn’t see her face, which meant that butthole could belong to any tiny sexy futa.
“Now, Lucy,” Elana said, “I want you to fuck your sister. Slowly Lucy’s eyes became defiant, her jaw set in a stubborn line. “I won’t,” she declared, her voice steady despite the turmoil inside her. “I won’t fuck my sister like some kind of toy.” Lucy was determined to repair the damage the acts she had just performed on Desiree had caused to her relationship with her sister. Lucy decided she had to defend her sister at all costs. Desiree had to know that the sex crazed woman that throat fucked her was not her sister. It was a product of Elana’s manipulations; nothing more. Lucy would never intentionally hurt her sister.
Elana smirked. “Oh, Lucy,” she said, her voice laced with amusement, “you will. You all will, eventually. It’s just a matter of time. Surely, you realize that by now. You’ve released the futanari within you. You can’t put it back in a cage.”
Lucy scoffed, looking away from Elana’s smug face. “I won’t give you the satisfaction,” she retorted.
Elana chuckled, turning her attention to Linda and Valarie. “Well, while Lucy is being stubborn,” she said, her voice taking on a more serious tone, “let’s see how you two fare.” Linda and Valarie exchanged a worried look. Elana walked over to them. “You two,” Elana said, “are a different story. You’ve both been quite cooperative so far, even if it has been unintentionally.” She looked at them each in turn, “But let’s see how you handle a different kind of challenge.” Elana’s turned to Valarie. “Valarie, darling, I want you to ride your sister. I want you to straddle Linda and ride her cock. Make her feel good, Valarie. Make her cum.”
“Elana, no,” Linda protested weakly. There was so little energy in the refusal, that it was practically an admission of surrender.
Elana ignored Linda, her focus on Valarie. “Now, I want you to do it slowly. I want you to savor every inch of Linda’s cock.” Valarie was ashamed and distraught. She looked at Linda. Linda’s eyes were dull and unfocused, staring straight ahead. Elana grinned. She knew that defeated demeanor would soon turn to enthusiastic participation. She removed the dildo from Valarie’s pussy, leaving the hole gaping and slick. She then went to Linda. “Linda,” Elana said, her voice soft but commanding, “lift up your ass. It’s time for you to experience the pleasure Desiree just had.”
Linda looked up. “Elana, please,” she pleaded quietly.
Elana ignored her protest. She lifted Linda upp from the seat of the chair with her left hand. He right hand pressed the tip of the dildo against Linda’s asshole, rubbing it in circles, making Linda squirm. “Relax, Linda,” Elana cooed, “I promise, you’re going to enjoy this.” Linda took a deep breath, trying to calm her racing heart as Elana slowly pushed the dildo into her ass. She endured it silently, grimacing as her ass stretched to accommodate the toy. Elana held it there, twisting it slightly, finally drawing out a yelp from Linda.
Valarie’s legs were loosened. She tried to kick Elana, but Valerie had little strength. She was accustomed to being served by others. She wasn’t a physical person. She only went outside to sunbathe. Elana handled her easily, guiding her onto Linda’s lap. Elana put her right arm behind Valerie’s neck and bent her forward, so Linda’s cock could be lined up with Valerie’s slippery fuck hole. “I want you to lower yourself onto your sister’s cock. Slowly, Valarie. Let her feel every bit of that sexy pussy.”
Valarie, her face flushed with arousal and a hint of nervousness, had to do what Elana said because Elana was pushing her down, and Valerie didn’t have the strength to resist. Linda finally came back to life when she felt Valarie’s long labia brush against her cock. Elana held Valarie’s hips, helping her descend slowly.
Linda shuddered pleasurably as she felt her sister’s tightness envelop her. Elana secured Valerie’s wrists to the chair, so Valerie was sitting upright on Linda. This kept as much of Linda as possible buried in her sister’s heat. Valerie could accomodate much more cock than Lucy could.
Elana then added a leather collar around Valerie’s neck. The other end of the chain which was attached to the collar was connected to the back of Linda’s chair. “There.” Elana said, giving Valarie’s bonds a tug. “Now, Valarie, you’re going to pleasure your sister. I would tell you to go slowly so that you both savour it, but you’re going to disobey. You will be fucking like whores when a ship comes in.”
Elana, with a satisfied nod, turned her attention back to Lucy. She picked up another collar from the table, identical to the one Valarie now wore. Lucy watched warily as Elana approached her, the collar dangling from her fingers. “Now,” Elana said to Lucy, her voice taking on a serious tone, “it’s time for you to join the fun.” She held up the collar, a wicked gleam in her eyes. “This is a special collar. It’s activated by proximity to a penis. The closer you get, the more it will constrict.”
Lucy’s eyes widened, a mix of fear and curiosity in her gaze. “What do you mean, constrict?”
“It will tighten around your neck, Lucy. The chemicals on the collar will mix with your sweat allowing them to absorb into your skin. They will make you crave orgasm. The closer you get to a penis, the more intense the sensation will be. But, when you move away, the collar will loosen.” Lucy swallowed. The taste of cum was still in her mouth. Her body was already responding to the thought of the collar’s power. “And Lucy, sweetie, here’s another catch. The collar not only affects you, Lucy. It’s connected to the dildos I’ve placed inside your sister. The closer you get to your penis, the more the dildos will vibrate inside Desiree. The more intense your desire, the more intense her pleasure will be.” Elana paused, letting the information sink in. “So, Lucy, you must resist. Resist for both of you. Because if you give in to your desire, if you ejaculate, not only will you lose the game, but Desiree will also reach her peak, and she’ll fill your womb with your own niece or nephew.”
Lucy’s jaw dropped in realization. She looked behind her at Desiree, who was watching them, her face full of concern. Lucy’s mind raced, the thought of Desiree’s pleasure being linked to her own desire sent a thrill through her. She turned back to Elana, her voice steady despite the storm of emotions inside her. “I understand. Desiree, I’ll resist. I promise. Elana is not going to do this to us.”
Elana smiled, a predatory smile. “I hope you do, Lucy. For both you and your sister’s sake.” Elana moved to the center of the room and spoke more loudly. “The same rules apply to Valerie and Linda. And here’s another little detail. The collars deactivate after the first team loses. So, you see, one pair of sisters will make it to the end. And it will be the pair who can resist their desires the longest.” In excitement she called out “Now, let’s begin.” Elana’s words hung in the air, a promise of the decadent challenge to come.
As if on cue, Lucy and Valarie began to react to the collar’s influence. Lucy’s face flushed, she began hyperventilating as she felt her dick stirring. Her cock, which had been semi-erect, began to harden further, growing visibly longer and thicker. Valarie, too, was affected. Her eyes glazed over, her body trembling as her own cock emerged, standing proud and stiff.
Elana watched, her eyes gleaming with satisfaction as the erect cocks grew, the scent of them increasing the futas’ arousal. “It seems our collars are working,” she commented. “You can feel it, can’t you? The desire, the need for ultimate climax. It’s intoxicating, isn’t it?”
Lucy bit her bottom lip, her eyes darting between Elana and her sister. She could feel the collar’s influence, the way it made her crave. Lucy and Valarie’s gazes flicked downwards, their eyes widening with anticipation as they observed the cocks growing. Valarie’s was already a good length, the head glistening with pre-cum, while Lucy’s was still rising, the shaft thickening and lengthening at a visible pace. They watched, entranced, as their cocks twitched and pulsed, reacting to the collar’s influence and their own increasing libido.
Elana, couldn’t help but feel satisfaction. She had them right where she wanted them, teetering on the edge of control, their bodies responding to the collars’ power perfectly. She could see the desire in their eyes, the way they licked their lips, their breaths short. “You see it, don’t you?” Elana asked. “The way your cocks continue hardening with your desire. It’s a beautiful sight, isn’t it?” She moved closer, her voice dropping to a conspiratorial whisper. “Imagine, if you will, the feeling of release. The intense pleasure that comes with orgasm. That’s what you’re fighting against, sisters.” Valarie’s eyes were pulled toward her cock, now a respectable length, twitch and sway with its own will. It was as if it had a mind of its own, drawn towards the source of her desire. She gasped as it jerked forward, the tip in front of her full, parted lips. The sensation was the only thing she could feel besides Linda’s turgid length buried inside her.
At the same time, Linda’s body convulsed as the dildos inside her began to vibrate. The sudden, intense stimulation made her cry out, her hands clutching the restraints that held her. The vibrations were intense, pulsing in time with Valarie’s heartbeat, filling Linda with a pleasure that was almost too much to bear.
Valarie’s eyes rolled back in her head, her body trembling with the effort to resist the urge to take her cock into her mouth. But she could resist returning her gaze to her delicious dick. She could feel the pleasure building inside her, the need to cum growing with each throb. She looked at Elana, her eyes pleading, “Please, Elana, it’s too much. I can’t ... I can’t hold back.”
Elana cruelly enjoyed it. “You can, Valarie. You must. “ Elana lied. Valarie leaned forward, her body straining against the restraints, the collar digging into her neck as she gasped for breath. The pressure on her throat was a harsh reminder of the power Elana held over her, a power that made her crave release even as it denied it. She could feel her heart pounding, her skin flushed red, and her cock throbbing with need. It was too much, the collar’s influence, the sight of the futas in front of her giving in to the same pleasure, the knowledge that she was powerless to stop it all. She was right on the edge, her body naturally responding involuntarily, her mind a whirlwind of desire and desperation.
“Please, Elana,” she begged, her voice hoarse from the strain, “I ... I need ... I need to cum.”
Elana’s smile widened, her eyes gleaming with sadistic pleasure. “I know, Valarie,” she taunted, “But you must hold back, right? You see, every time you cum, your desire for it grows. And every time you cum, you drive your sister towards climaxing inside you. And your sister’s orgasm will increase your own pleasure. It’s a wonderous cycle, isn’t it? And I do love watching you sisters squirm.”
Valarie’s eyes flicked back to her enticing cock. Pre-cum was trickling down the front of it now. With a whimper, she leaned forward, her lips parting as she brought the tip of her cock to them. She hesitated for a moment, her eyes locked with Elana’s, as if seeking permission. Elana nodded.
Valarie’s lips closed around the head of her cock, her tongue flicking out to taste the salty pre-cum. A jolt of pleasure shot through her, making her gasp, her eyes closed. The collar around her neck tightened, choking off her gasp, the pressure sending a wave of panic through her. At the same time, the dildos inside Linda began to vibrate with renewed intensity, the pulsating pleasure almost sending her careening toward climax.
“Mmm, that’s it, Valarie,” Elana encouraged, her voice a warm silky melody. “Taste yourself. Feel the intensity grow. Let it consume you.”
Valarie could feel her cock throbbing in her mouth. Her body was trembling with the effort to resist the urge to take it deeper, to suck herself to completion. The collar was a harsh reminder of her predicament, choking her “Valarie, please stop!” Linda’s voice was a desperate plea, her body writhing in her restraints as the dildos continued to pulse inside her. “You can’t ... you can’t do this to me; to us! I can’t impregnate my sister!”
Valarie hesitated, her lips still wrapped around her cock, She felt a mix of desire and abhorrence. She could feel instinctual need tricking her mind. It altered her reasoning o allow her to give in to what she wanted. But she could also hear the distress in her sister’s voice.
“I can control it, Linda,” Valarie said, her voice muffled around her cock. “I can come without making you come. I promise.”
Elana, watching the exchange, felt her heart leap. This was what she had been waiting for, the sisters turning against each other, their desire clouding their judgment. The ultimate destruction of their former morals was near. They would wholely become what they claimed to detest.
“Valarie, you can’t!” Linda cried, her body convulsing as the dildos inside her shifted, sending shocks of pleasure throughout her. “You don’t understand ... you have to fight against Elana ... it’s not just about us. It’s about ... about everyone here.”
Valarie’s eyes flicked to Elana, a realization broke through to her. She pulled back, her lips leaving her cock with a wet pop. The collar around her neck loosened a little. She could feel the pleasure receding somewhat, the need to cum subsiding, but only slightly.
Meanwhile, Lucy, watching the scene unfold, was undergoing a surge of desire. She had always found the sisters’ predicament arousing, but seeing Valarie playing with the edge of orgasm, her body flushed and trembling, was almost too much for the little woman to bear. Without a word, she bent down, her lips wrapping around her own cock, which had grown significantly since the contest began. She could feel it throbbing in her mouth, eager for release.
“Lucy, no!” Desiree cried, her eyes wide with panic. “Don’t you dare! You can’t!”
Lucy ignored her, her eyes locked onto Valarie’s trembling body. She sucked her dick into her mouth, her tongue gathering her own pre-cum. The sweet flavor propelled Lucy’s arousal even faster. She could feel her cock warmth against her lips. The glans sending out ripples of unbearable sensation.
“Lucy, stop it right now!” Desiree hissed, her voice low and urgent. “You’re falling into Elana’s trap. You’re gonna make yourself pregnant. I will be helpless to stop myself if you cum! You decide what you want. Your dick doesn’t decide for you.”
Lucy paused, her lips still wrapped around her cock, she was confused. The reduction of air caused by the tightening collar made it difficult to think. “I know what I’m doing, Des,” she murmured, her voice muffled. “We can enjoy this, as long as Valerie is closer to cumming than we are.”
