Her face was wet with saliva and Sophie's juices. The sound of Amber's voice brought Sophie back from her pre-climatic state and she closed her eyes, remembering that so many people were watching her. She also remembered that her performance and reaction would reflect on Thomas. She tried to relax again and her climax grew once more as Amber resumed her licking and nibbling.

From the outer edge of the crowd, Thomas watched as Sophie's tight body responded to Amber's mouth. The sight of the two naked women, both so familiar to him, was very arousing. He began a slow stroke of his engorged cock as he watched.

He remembered Amber as she had been when she had taken his virginity, had taught him the skills he then used so well to pleasure other women. Always, however, he had returned to Amber's bed until he found Sophie and, he was sure, real love. He felt guilty and a surge of love as he watched Sophie reacting with pleasure to Amber's ministrations knowing she would also feel vulnerable and humiliated.

In spite of herself Sophie started to climax, arching her back and sobbing. Amber drew out the orgasm expertly so that Sophie cried out, pleading, until she was allowed to peak with a scream of pleasure. Amber sat back on her heels with a satisfied smile.

"There, it feels good when an expert handles you, doesn't it?" She laughed, looking down coldly at the spent form on the bed.

Sophie, still groggy from her orgasm, felt hands untying her legs. Jeremy appeared in her narrow field of vision. He leaned down until she could feel his breath as he whispered.

"How are you, sweet Sophie? Surviving so far?"

"May I get up?" Sophie pleaded, glad that it was over.

"Yes, yes, by all means! The best is yet to come." He said as he released her wrists and helping her to sit. Sophie's heart sank; she sat up rubbing herself where the ties had cut into her flesh.

"We recently acquired a new devise and we have decided to take advantage of this occasion to demonstrate it for the members." Jeremy said helping Sophie to sit up.

She searched the faces for Thomas but, when he had seen her sitting up, he had stepped back behind the others to hide from her eyes. The gathered crowd had drawn closer and now Sophie recognised some of the men from her time in the ballroom. Many of the male members continued to masturbate or receive oral sex from the females having started while Amber was working on Sophie. Sophie saw a circle of hands stroking rigid cocks and swallowed nervously.

Jeremy was helping her off the bed, she was still shaky and he held her around her naked waist. He led her towards a strange looking contraption. To Sophie it looked like a cross between a child's swing set and a hammock.

"Here, let me help you, Sophie." Said Jeremy.

He lowered a canvas hammock and indicated that she lie back in it. Nervously, Sophie obeyed and found that it accommodated her shoulders and back but, in order to keep her feet off the floor, she had to place them in stirrups on either side of the hammock. This forced her knees wide open in a most suggestive way and she felt the air cool the dampness that the position revealed.

Watching her get settled, Jeremy seemed impatient. His erection was back to its former glory and he unconsciously stroked it. Once her heels were secured in the stirrups, two women took her hands and held them out away from her sides. They cuffed them to rings in the frame so that Sophie was totally helpless. The sling was adjusted to allow Jeremy to approach her open legs; her swollen, exposed sex was at the height of Jeremy's hips.

Somewhere, music started and Jeremy dropped his robe to the floor. His hand explored Sophie where Amber had moistened her and where she was dripping from arousal, his fingers probing and opening her. Satisfied she was ready he placed the tip of his rigid cock at the entrance.

" Are you ready, Sophie?" He asked above the swelling music.

She tried to speak but couldn't so she nodded. At that Jeremy pressed into her and she felt the hardness open her, stretching her. She gave a cry part pain, part pleasure.

"Now, my dear, as an added thrill we are going to use a switch on you. Thomas has told me that he has already initiated you to the sting of the whip so it should not be so strange for you. Are you ready?"

Before Sophie could answer she felt a sharp, stinging pain on her buttocks. She didn't cry out and was concentrating on the slow rhythm of Jeremy's cock as it glided in and out. The motion set the sling swinging gently. As he moved in her Jeremy caressed her clit in a way that sent waves of pleasure coursing through her. Just as she felt a climax start to build another, sharper, strike of the whip made her cry out. She wasn't able to see who wielded the whip but thought it must be Amber. In fact it was Thomas who had been ordered by Jeremy to comply.

Thomas remembered their time back in the hotel room when he had used a switch on Sophie's flesh. He had been very aroused by it and, after getting acclimatized, so had Sophie. However, he had used the switch as punishment and now he felt her humiliation was punishment enough. He was conscious of Jeremy watching him with his hooded eyes and knew he should be hitting Sophie with more conviction. Did she know it was he who held the whip, he wondered. He gave her reddening cheeks several sharp slashes so that Sophie cried out.
