Sarah's fingers worked faster in her pussy, feeling the orgasm slowly starting to build. Bethany was making all sorts of sexy noises as the other woman licked her cunt, and was keeping her hand in the other woman's hair to keep her mouth close. Sarah's mind alternated between what it would be like to receive such pleasure, and what it would be like to be forced into giving it. She could almost feel the rope on her wrists, so soft and yet so firm, and the taste of pussy on her mouth. It was almost as if she was the woman kneeling in front of Bethany, but she couldn't be, as she was sitting in a chair across from them... wasn't she?
Bethany arched back in the chair, letting out a satisfied moan of pleasure and drawing the other woman's head away. Sarah desperately tried to bring herself to orgasm, but for some reason couldn't quite tip herself over the edge. The voice said she should wait a little bit longer, as there was another treat for her. The voice said if she waited, she'd have a very good orgasm and that she was very good for not coming yet. Sarah knew the voice was right and that she should wait. Plus, the video was very interesting and it was important to keep watching it.
Bethany stood up, the other woman looking up in adoration at her Trainer. Bethany pulled her into the chair and sat her upright, her hands still locked in place with the rope behind her back. With her arms pulled back like that, the other woman's breasts were pushed out and up. Sarah thought they looked very good. The voice said it was time for the other woman to get her reward for obeying her Trainer, and that Sarah might get her reward too, now, for watching the video all the way through. The voice also said it was OK for Sarah to watch them properly now, and that Bethany and the other woman didn't mind. She said the other woman was a slut and liked to be watched during sex. Sarah was very happy to be able to watch.
Bethany had locked the slut's legs wide apart with a bar that had two leather cuffs at the end. The cuffs were fastened around the slut's ankles. Sarah's pussy twitched as this was done, and she imagined herself in that position, her cunt exposed and ready to take what her Trainer wanted to put in it. Sarah thought this would be wonderful to be open and ready.
She could see Bethany talking quietly to the slut, but couldn't hear what she was saying. Bethany leant forwards and stroked the slut's face, before leaning in and kissing her again. The slut kissed her back eagerly, and Sarah pushed a third finger inside herself as she saw their tongues intermingling. Her pussy was soaking wet now.
Bethany now knelt down and began to lick the slut's pussy, reaching up with one hand to push a finger inside her. Sarah couldn't believe how turned on she was getting, and as she saw the slut pant, gasp and groan, wriggling and writhing on the chair she pumped her fingers harder and faster into her own pussy. It seemed like only a few seconds before both her and the slut came simultaneously, and Sarah could almost believe it was her own cunt that was being licked as the waves of pleasure washed through her. She didn't stop stroking herself until Bethany pulled away and gently wiped her mouth clean, and even then she could feel little after-ripples drifting through her.
Sarah relaxed back into the chair, her hand coming out of her cunt and resting on her thigh. She felt tired after the orgasm, and her mouth was dry. Reaching down to one side of her, she found the glass of water and took a long swallow. The voice said the training was nearly over, and there was only one more thing she had to do before she could start working for the company properly. Sarah very much wanted to work for the company if she was going to have this much fun every day!
Bethany was suddenly in front of her, fastening a collar around Sarah's neck that looked identical to the one round the other woman's neck. As she fastened it into place Sarah thought it felt very natural and comfortable, and that Bethany was the proper person to do it. Reaching forwards, Bethany attached a leash to it and pulled, so Sarah got to her feet and followed her out of the door. The voice said it was good to have someone leading you on a leash so that you didn't have to worry about getting lost.
Sarah felt a little confused, though. Was Bethany just leading her on the leash, or was the other woman/slut with them too? Before she could think too hard about it they entered another room, and Sarah looked around to see what was happening. Ahead of her was a table -- two tables -- and each one had a number of straps on them. Bethany lead Sarah /the slut onto a table and told her to kneel on all fours. Sarah knew she had to obey her Trainer to pass the training and be allowed to work for the company, so she climbed up.
To her left she could see the other slut doing the same thing -- couldn't she? Or was she on the right? Bethany was stroking her back and arms as she knelt, and the feeling was so nice she forgot to worry about whether the slut was here too. Bethany walked around in front of her, beautifully naked now, holding a blindfold. Bethany said that she knew Sarah wanted to feel everything, and not be worried about what she could see or not see, so she was going to put the blindfold over Sarah's eyes. She asked Sarah if she trusted her, and Sarah said of course she did. The blindfold went over her eyes, sitting comfortably on her face, and Sarah relaxed. It wasn't important whether the slut was here too, it was only important to obey and to make a good impression.
Kneeling on the table, Sarah could feel hands wrapping leather straps around her wrists. Bethany's voice told her to spread her legs so that she could lock her legs in place too, and a moment later Sarah felt her ankles being fixed in place too. The leather felt wonderful on her skin, and she knew she looked very sexy on the table, exposed and ready. Bethany said so, quietly in her ear, and added that Sarah looked like a wonderful sexy fuck-slave that needed to be made to cum. Sarah nodded. That was exactly right. She was a fuck-slave and needed to cum. It was important to obey her Trainer.
Bethany's mouth came down to Sarah's and kissed her again. Sarah knew it was wonderful to kiss her Trainer. Her Trainer's voice said she was getting wet and ready to be fucked, and Sarah knew this was correct. She could feel herself getting wetter. Her Trainer said she would always be ready to be fucked from now on, and Sarah agreed again.
She felt a hand between her legs, teasing and stroking at her cunt. She tried to move back onto the hand, wanting it deeper inside her. A sharp slap to her ass was the response as her Trainer said she should stay still, so she did. Her Trainer said that fuck-slaves didn't get to make themselves cum, and that it would always be done to her. Sarah knew she was a fuck-slave, and so this was correct. She held herself still as the hand continued to work on her cunt, rubbing and sliding all over it. Then it went away. Sarah/fuck-slave wanted it to come back, but knew she mustn't ask for it. She lifted her head up, eyes still blindfolded, listening for what would happen next.
She could hear movement around her, maybe more than one person? The fuck-slave knew the only thing better than pleasing her Trainer was to please more than one person. She could smell something in front of her, and a voice said she should open her mouth, so she did. As soon as she did, she felt the tip of a cock enter it. The voice said that all fuck-slaves loved to suck cock, so she began to kiss and nibble at it, running her tongue over it. She could hear grunts of approval from above her.
Her Trainer's voice asked if she was ready to be fucked and to be allowed to cum. Sarah nodded, without letting the cock go from her mouth, and straight away she felt something sliding into her cunt and start to steadily slide in and out of her. The motion was very regular, but gradually increased in speed. The voice said that when the fuck-slave did her job properly, she would be allowed to cum. Sarah opened her mouth wider and began to suck and lick and kiss the cock in it, leaning forwards into her bonds to do so. All the while the cock in her pussy pushed back and forth, back and forth, slowly increasing in speed. Sarah thought it might be some sort of machine, set to fuck her endlessly until she made her new Trainer cum in her mouth. The thought of how she must look, slavishly giving head whilst being fucked by a machine, made her even more turned on.
She began to bob her head, running her lips along the length of the shaft inside her mouth. Her tongue swirled around the head of it, and she felt two hands grip her hair as the man started to fuck her face in earnest. As he did so, the cock in her pussy started to speed up more, pounding into her, and it was joined by a vibrator running over her clit. Gasping and grunting, taking cock in both her pussy and mouth, Sarah was lost in the sensations. She could feel her pussy starting to contract and spasm, yet her orgasm was denied. She could feel herself building up, each wave of sensation better than the last, but something was stopping her from cumming.
