Rider and Sakura
Rider waited patiently for Emily to recover, enjoying simply standing there and watching the enticing show Sakura was putting on as she writhed and moaned in response to the constant torment being inflicted on her. After a few moments, her hand trailed down her body lazily, and she began to masturbate. Not long after she had started, though, Emily finally recovered, and addressed Rider once more.
"Well", she began, getting up off the bed, "we can start by switching the current weights for some heavier ones."
Rider gave a sadistic smirk in the direction of the obviously-upset Sakura before happily going to perform her allotted task. Her excitement grew when she noticed Emily heading for the wall, out of sight of Sakura, and picking up a cattle prod, before walking behind the frantically-nodding captive, who was unaware of the extra torture Emily intended to inflict on her.
Rider, still smiling, moved over to the table where the weights were.
"Hmm, I think I should start with these", she said, picking up a set of breast weights, probably almost double the weight of the already-too-heavy ones hanging from Sakura's tortured mounds. Sakura began to beg frantically as she saw what Rider was doing.
"N..ah.. no.. ah.. plea..ah..se Ri..der.. no...", she said, weakly, as her sadistic captor approached her with the weights.
Rider, of course, simply ignored the pleas, simply becoming more aroused by the captive's begging. Removing the existing weights, Rider let Sakura relax for a few moments, an evil smile on her face, before attaching the new ones, one at a time.
"AAAAAAHHHHHHHH", Sakura screamed as the new weights pulled downwards on her squashed breasts in an agonising fashion.
Rider simply laughed at her former master's suffering.
"Aww, does it hurt", she said, mockingly, highly-aroused by the sight of her master's now painfully-stretched breasts.
Then, satisfied with the effect of the first part of her assigned task, Rider moved on to the second part, preparing several new weights, again about twice as heavy as the previous ones.
"N..AAAHHH..nn", Sakura stammered, her breasts still in pain, but Rider once again simply became more aroused by the begging and the increase in volume of Sakura's tortured moans.
Removing the previous weights, Rider attached the new ones in their place with a lewd smile on her face. As soon as she released the weights, she got the expected reaction from the captive.
"AAAAAAAAAAAHHHHHHHHHH", Sakura screamed as the new weights put even more pressure on her already-tortured pussy and clitoris.
Sakura's was now panting and hyper-ventilating, unable to stand the pain she was now in. Unfortunately for her, though, that simply made Rider more aroused and more determined to see how much suffering they could cause to the unfortunate prisoner.
Rider stepped back and admired the beautiful sight of Sakura's agonised facial expressions and tormented body, her hand once again trailing down to her pussy and beginning to play around with her clitoris, whilst the other went up to her breast and began to play with that. Then, after a few moments, Emily spoke.
"I wonder how she'll like this", she said, causing Sakura a moment of confusion before she felt a jolt of pure agony.
"AAAAAAAAAAAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHHHHHH!!!!"
Sakura let out an almighty scream as the cattle prod began discharging its electricity into her tender flesh, and began to desperately push herself away from the prod, only for Emily to continue pushing it towards her, causing her more pain on her clitoris and pussy to add to the agony of being shocked. The torture was now unbearable. Of course, Rider had absolutely no intention whatsoever of stopping. This was simply way too much fun.
"Em..ah..ily", she said, continuing to masturbate to the sight, "what should I do next?"
