The Contest

It started small. Lisa pressed forwards slightly, experimentally, and Diana felt herself gasp as the dildo moved with her. It pressed forwards, into her pussy, and she shivered. A moment later, she pushed back, driving it forwards with her lower self, though this action also served to arouse herself, and she saw Lisa gasp in surprise as well.

After that, it was one. The two of them got into a rhythm, pushing against one another, the dildo moving back and forth in a way that made them squirm. The friction was pleasant, the motion sublime. Each of the sisters felt it, growing more confident with each stroke, driving deeper with each thrust. Diana felt herself growing more and more focused on the moment, on the feeling of being entered. Each time it did so, her body screamed for more, she pressed herself against it, impaled herself on it, it filled her with a solid length of rubber, unyielding and hard. She moaned, the sound torn free from her lips.

Lisa was doing little better. She was gasping with each motion, driving the dildo back and forth at the same time as her sister. The cameras watched, the chat ticked by, neither of them noticed or cared. Too caught up in the experience, too caught up in the moment.

Diana felt the dildo hammering away inside of her, each touch of it against her inner walls making her flush and moan as new pleasure poured through her body. Her skin felt hot and tingly, and each breath was an effort. Her legs grew numb, and she could barely keep herself standing. She realised that her lower self was dripping now, the arousal of the moment bringing her closer and closer to the edge.

She wanted to abandon herself to it, to feel the pleasure of the building orgasm. Yet, she did not, the feeling of the camera on her was constant, and she knew that if she did, she would be punished. The thought sent a twinge through her lower self, making her moan even more loudly. Yet, she did not want to give up too easily, she wanted to fight, she wanted to last.

Diana mustered her resolve, gathering all of her strength and willpower as she fought against the need to cum. She felt her face heat up, she felt her legs buckle and yet she fought on. For a long time, she fought. She didn't know how long. The passage of time was lost to her, all she felt was the pounding entrance of the dildo, the motion of it as it played against her body, the sweet but growing threat of climax that built and built with each passing moment. As the game went on, Diana felt her arousal soaring, growing more and more just as her pussy grew wetter and wetter, the feeling of her sister's body so close, the constant pleasure radiating from her lower self, it almost made her lose her mind,

Still, she fought. Still, he plunged onwards. Lisa's face was red with her own arousal, her body was tingling all over, Diana was sure. Each time her sister felt the dildo's touch, she moaned, more and more loudly. She too was reaching the limit of her ability.

Press on! She just had to keep going and she could win this!

Diana could only barely hear behind the rush of blood to her ears, her throat was dry, and her lips felt chapped, the growing pleasure in her body was racing through every nerve and cell, so that her whole world felt focused on her lower self, like a star growing and growing, her arousal burned red hot.

Lisa was gasping in turn with her pumps, the two sisters thrusting in turn, each one fighting the other with all that they had. Yet, the victor of the contest was decided in a single swift move. Realising that she was going to lose, Lisa managed to **** her body to work, her hands shot out, pressing against Diana's shoulders, and before the elder sister even realised what was happening, she had been drawn into a deep kiss.

Sparks flew in her mind as she felt Lisa's lips pressed against her own. Her own sister? Kissing her? What was this? Lisa kissed her hungrily, driving her tongue in deep, and even as she did this, her hands moving again. Diana yelped into the kiss as she felt Lisa's fingers find her nipple. Her sister started to twist it gently, rubbing her fingers over it, and then stroking it. Diana moaned anew now. Lisa had always had sensitive breasts, and as a result, she knew what felt good. Diana had never before done much work with her breasts, it had always been a simple prelude to her pussy or clit. Now she felt her sister's hand, and her chest exploded with pleasure. Lisa's fingers were nimble and sure, stroking and teasing, pinching and prodding. Diana felt her eyes go wide, her mouth open in a long moan of ecstasy as her lower body exploded with ****. Pleasure swept through her, the climax dancing, searing, _screaming _though her very being. Her eyes rolled back, and her legs went numb, her heart hammered and her breath grew short. Lisa had to quickly catch her as the sheer strength of the orgasm brought her crashing to the ground.

The dildo exited her body as Diana tried to muster her strength. Her muscles quivered, her skin sang in the afterglow of her experience. She was gasping, looking up at Lisa.

"That was..." She gasped..."That was..."

"Nice try." Lisa said. "But I guess I win, Diana. Hope you like your punishment." She winked, they both knew she would.
