Kim could feel Bill's stiff cock pressing against her tight anus; she concentrated on trying to relax the muscles of her sphincter to allow him to penetrate her. The last time he had fucked her anally she had been in bondage just like now but that time he had lubricated her generously and stretched her arse by inserting the big butt plug into her. She remembered the feeling as he pushed the plug hard into her, how painful it had been but she had been determined to endure it to please him. She'd told him that she wanted it in her, to have him insert it, make her have it and only her safe word was going to be the bar. He'd taken her at her word and had forced the huge thing into her arse and then fucked her cunt. She smiled at the memory of it, being double penetrated, the feeling of being completely full. Then he'd pulled the plug out and slipped his cock into her in its place. She recalled the ease with which his erection had gone into her. However, this time there was obviously going to be no pre stretching, no lube, he was going to take her up the arse without employing any of the previous preparation. She set her mind back to making it easier for him to enter her then winced as he forced his cock inside her. It slipped in and soon his balls made contact with the lips of her cunt.
'Thank you Sir,' She said as he began to gently fuck her arse. 'Are you going to cum fuck me till you cum Sir?'
'I'm going to cum and it will be in you but not yet my compliant little whore. I have a few surprises for you first.'
'Surprises?'
'Yes. When I advertised for men to fuck you I didn't only get replies from men.'
'Oh?'
'Seems that the thought of having you in bondage attracted quite a few women too, especially as I'd said that you will do exactly as you're told.'
'I will Sir.'
'Good.' Bill said as he pulled his cock out of her.
Kim heard him walk away from her and then heard him return a few minutes later. He wasn't alone as she could hear the distinctive sound of stiletto heels clicking across the floor toward her. She was aware that Bill was standing near to her and then he pulled the blindfold off her. Her eyes took a moment to adjust to the light and then saw there was a woman, about the same age and build as her, standing naked in front of her.
'Kim, I'd like you to meet Gillian. She replied to my advert and she was very keen to have the opportunity to play with you. I liked what she said she wanted to do to you and I invited her along and agreed to what she proposed. You're going to let her do whatever she wants to you, aren't you?'
Kim looked at Gillian's face and she smiled back at her. Kim couldn't help but wonder if the woman had witnessed what had transpired with the four men and indeed if she'd seen Bill fucking her arse.
'Yes Sir.'
'Good. Gillian you may begin.'
Gillian walked slowly around Kim and stood behind her then she felt her fingers touch the lips of her cunt. Gillian pushed one finger and then two into her and Kim could feel the oozing spunk and Gillian's fingers worked back and forth in her hole. Slowly she eased a third finger into her and prised them apart, opening up Kim's pussy. After a few moments stretching Kim felt a forth digit enter her before Gillian continued to work her fingers in and out of Kim's dripping orifice. The warm spunk trickled down her thighs and she could feel herself getting wetter and wetter as the woman fingered her already sopping cunt. Gillian withdrew her fingers and then felt the whole of the woman's hand begin to enter her. She twisted and thrust her hand and slowly, fractions of an inch at her time worked her hand into Kim's cunt. Kim felt the knuckles go in and then gasped as Gillian's fist entered her vagina. She could feel the walls stretching to accommodate it and although her hand was smaller than Bill's it still felt like it was filling her cunt. She though back to when Bill had fisted her, the thrill she felt when his hand finally went into her cunt and how it stretched her. Even the biggest courgette she had taken felt tiny compared to his fist. Gillian began to increase the speed of her movements and Kim could feel the beginnings of an orgasm welling up. As Gillian thrust her hand into her more and more rapidly Kim got closer and closer to cuming.
'Please Sir, may I cum?' Kim said between gasps as she fought to stave off the inevitable orgasm.
'Yes, my gorgeous little slut, you may come for me.'
Kim pushed all thoughts from her mind and concentrated on the pleasure that Gillian's frantic movements were inducing and then she felt the flood gates open as wave after wave of the most intense orgasm coursed through her body. She bucked and trembled as she came straining against her bonds and moaning loudly. As the intensity of the orgasm subsided Kim tried to catch her breath, she could feel the hand inside her stretching the walls of her vagina even more tightly and realised that Gillian was slowly clenching her fist. Kim looked at Bill.
'She's making a fist!' She said, more loudly than she'd intended.
'Shall I tell her to pull her hand out of your cunt?'
'Yes please Sir.'
'Gillian, pull your hand out of my sub's cunt right now,' Bill commanded.
As the woman began to withdraw her hand Kim realised the mistake she'd made. As she tried to gather her thoughts and beg Bill to get her to unclench her fist first she felt the full force as Gillian yanked her hand out of her. Kim let out a scream as Gillian's hand was dragged out of her. Kim yelled. Gillian remained silent and stared at Kim then turned and spoke to Bill.
'I've done what you wanted me to do, is it my turn now?'
'Yes, she's yours so have fun with.'Gillian turned and walked toward the corner of the room where there was a chair. As she walked away Kim looked at Bill.
'You told her to do that?'
