Rider
Her captor paced around for a few more moments, leaving her eagerly anticipating what was to come next before, finally, he spoke.
"Well, I suppose we ought to warm you up before we get started", he said, walking away for a few moments before approaching her from behind.
Rider felt a sudden pull on her dress, followed by the feeling that it was being cut away. Shortly after, she felt the dress drop to the floor, leaving her exposed, wearing only her boots, her gloves and a pair of very damp panties, her arousal only growing further from the humiliation of being bound and exposed in this way.
"My my", her captor said, his hand reaching down into her soaked panties, "I haven't even touched you yet and you're already this wet?"
A blush of embarrasment came over Rider's face from his words, and she began to moan with pleasure as his hand reached into her panties and started to rub at her damp folds. Her moans grew louder when he reached up with his other hand, roughly groping her ample mounds, causing her to let out the odd hiss of pain which only increased the intensity of the pleasurable moans. Then, he leaned in and began to nibble at her ear, the sensation adding nicely to the pleasure she was already feeling, her juices flowing ever-faster as he pleasured her expertly.
"After all, I'd rather you be nice and sensitive when the real fun starts", he whispered into her ear as he continued to play with her helpless body, causing her to shudder with delight at the thought of what was to come.
Rider continued to moan with pleasure, beginning to buck her hips into him as she enjoyed the rough, somewhat degrading but highly-pleasurable treatment he was inflicting on her, and eagerly anticipating the torment that was to come.
