Rider and Sakura
Rider continued to watch uncomfortably as Wynn's tendrils continued their relentless tormenting of her helpless master, the arousal she was feeling from the sight only making her feel worse. Wynn laughed at the sight before walking over to the bound servant, resting her head on her shoulder and beginning to gently trail her hand down her body.
"Look how wet you are. I wager that you feel guilty about this, feeling wanton at the sight of your beloved Sakura plundered like this", she said, beginning to rub the servant's wet slit.
Rider moaned with pleasure at the woman's skilful touch. This was gentler than she usually desired, but the sight of Sakura being tortured was making her highly aroused, and the humiliation of being pleasured against her will and made to enjoy her beloved master's torture made it even worse. She felt absolutely awful, hearing Sakura's agonised moans and screams and finding pleasure in them. Then, as if what she was doing already was not enough, she began to spread Rider open, tracing her finger around the hard nub, bringing the servant yet more unwanted pleasure.
"And you are going to come as you watch her suffer", Rider's tormentor continued, beginning to rub her.
Rider let out a scream of pleasure as she felt a tingling sensation from Wynn's fingers, the woman clearly using magic to increase the sensation. She was becoming more and more aroused, both from the woman's touch and, also, from the sight of her master being abused.
Sakura, meanwhile, was also screaming, but for very different reasons. She felt the shadow around her chest tighten, allowing her only shallow breaths and leaving her feeling almost like she was being suffocated. At the same time, the thorns dug into her breasts and nipples even further, tugging and squeezing her, every movement bringing another jolt of horrible pain, and more moans and screams from the defenceless girl. Meanwhile, the tendril in her ass continued to grow thicker and thicker, stretching her uncomfortably as it continued to thrust harder and harder, bringing more moans of both pleasure and pain.
Sakura continued to pant breathlessly, emitting constant moans of pain and some pleasure as the tendrils continued to torture and ravish her. Then, suddenly, she felt another tendril insert itself into her folds. The captive girl screamed once more as she was stretched open well beyond what she would usually expect, causing her much pain and discomfort. Then, the tendril began to vibrate madly, pushing the ribbed tendril against her sensitive spot, increasing the pain yet further but, also, bringing her significant pleasure.
Sakura's mind was now completely losing control, the combination of the pain and pleasure being inflicted on her simply too much. She continued to moan uncontrollably from a mixture of agony and ecstasy, her arousal growing more and more, her pussy becoming wetter and wetter. Then, one of the tendrils began to suck on Sakura's tortured nub, bringing her yet more arousal and making her scream even louder.
All the while, Wynn continued to play with Rider, the servant's ability to resist the sight in front of her becoming lesser and lesser. She began to subconsciously rock herself into Wynn's touches, her moans now heavy and frequent. Her face, though, was a mixture of distress and lust, enjoying the sight but hating herself for the fact that she did. Sakura, of course, was in no state to reassure her servant of anything right now, her own pleasure and pain overwhelming her as the two of them both approached orgasm.
