Chapter One

"Where have you been slave? 3 minutes late, you'll pay for that later. Put the tray down and kneel at the end of the bed" Mistress Sue shouted.
It had been six months since Mistress Sue moved in and became Kate's lover. I had been Kate's slave for two years before that, now I was slave to them both and my life had become consumed by my constant frustration. Mistress Sue was far crueler than Kate and was determined to drive me completely insane with desire. Whereas Kate would let me cum every month or so, Mistress Sue had shown no such mercy and I had not been allowed an orgasm since she had moved in. Kate had almost taken a back seat and just let Mistress Sue do whatever she wanted with me, which usually involved merciless teasing and pain.
With trembling hands I carefully placed the breakfast tray by the bed and knelt at the foot of the bed, naked apart from the tight metal chastity device, mercifully not fitted with the spikes today.
Kate was laying next to Mistress Sue, her hands were loosely tied with cord to hooks in the headboard. Mistress Sue leant over and kissed her, letting her hand slide down her body until it reached her moist pussy. She pushed two fingers inside her and she moaned as they kissed, my cock was already straining inside it's prison.
These games had become a common occurrence over the last few months. Mistress Sue had brought out a submissive side in Kate that she didn't know she had and would often be tied to the bed while Mistress Sue would tease her as they made love. Kate would beg and plead with Mistress Sue as she licked her clit, keeping her on the edge, then leaving her pussy alone as she tickled her stomach, feet and arms until Kate was pleading for mercy. These games would always end with Kate being brought to an intense and satisfying orgasm. Of course I would usually be in the room while this was going on, sometimes laying on the floor where I'm required to sleep so I could hear it, sometimes kneeling by the bed in case I was required for anything. Either way it was always an excruciating torture that they both relished making me endure.
"Please lick me, make me cum" Kate pleaded in a soft playful voice. Mistress Sue started lightly circling Kate's clit with one finger, Kate raised her hips, trying to increase the stimulation but Mistress Sue expertly kept her finger away from directly touching her clit. Kate moaned and giggled "Pleeeese, you're so mean, go on, I really need to cum"
"I don't think so, not today" Mistress Sue said as she removed her hand.
"Oh, you cow, please don't tease, get you're tongue in there"
Mistress Sue laughed "No, I don't want you to cum right now"
"Well untie me then" Kate said with slight annoyance in her voice.
"No, I don't think I want to" Mistress Sue had now rolled over on top of Kate and was straddling her, their pussies almost touching and she was lightly running her fingers up and down Kate's armpits, making her laugh and struggle. "GET OFF ME!" she gasped in between fits of laughter.
After several minutes of tickle torture Mistress Sue got off and left the room, leaving Kate breathless and sweating, still tied to the bed. I kept my head down, not wanting to catch Kate's eye as I knew she would take it out on me if she thought I had enjoyed seeing her suffer. Although the dynamic had shifted over the last few months and Mistress Sue had taken the lead recently, I was still very much Kate's slave as well and would suffer horribly at her hands.
When Mistress Sue returned she had a leg spreader in her hand and also a box. She put the box down on the dresser and walked over to the bed with the leg spreader.
"Come on Sue, that's enough for now, I need a pee, untie me" Kate said, slightly exasperated.
"I'll decide when you've had enough" Sue said with a slightly stern edge to her voice, she bent over and kissed Kate passionately on the lips.
"Oh fuck you, let me go" Kate turned her head away, she was getting more annoyed now and was pulling at the cords to try and get her wrists free.
"I don't think so" Mistress Sue straddled Kate again this time facing her feet and pinned her thrashing legs to the bed. She attached one cuff of the spreader bar to her ankle then lifting herself up, grabbed her other leg and despite Kate's struggles she got the other ankle cuff on. Mistress Sue is six feet tall and much heavier than Kate and was able to overpower her easily.
"What are you doing you bitch, I'm getting tired of this game, let me go"
"I think it's time you learnt your place Kate, we've played games long enough, I know you, I know what you want, and I'm going to make it happen"
"What do you mean? I like to feel helpless sometimes, who doesn't?, but just for a bit of fun. What are you saying? I've got to be your slave now or something?"
"YES, that's exactly what I'm saying, your not getting off this bed until you understand and accept that I'm in control now, you can still have your little pet to torment, but you belong to me now, you're my slave. And the sooner you accept that is your place and that's what you want, the sooner we can move on" With that Mistress Sue got off the bed and picked up the box from the dresser, as she brought it closer I could see what was written on it 'Neosteel'.
"What the fuck is that?" Kate said, glaring at Mistress Sue as she struggled against her restraints.
"Just something to help remind you of your new position" She reached inside and pulled out a chastity device. Made of polished metal with black edging, it looked cruel and vicious, there was something medieval about it.
Momentarily Kate stopped struggling and just stared at it, then "You can't be fucking serious" she shouted and struggled even more.
Mistress Sue sat on the side of the bed and gently put two fingers on Kate's lips "Shhhhh, don't try and fight it, this is what you really want, we both know it"
"No it fucking isn't" Kate said hesitantly "Please, just untie me and we can talk about this" Kate's thoughts we racing, when she saw the chastity device her heart skipped and she couldn't deny she'd felt a moistening of her pussy. Yes, she had been curious about chastity and being dominated by someone, always a woman though, the idea of a man telling her what to do repulsed her. But this was too real, too quick, the device looked evil, there was a certain permanence about its appearance.
"Well, it doesn't really matter, it's going on whether you like it or not" With that Mistress Sue started separating the parts of the device. Then she laid over Kate again, pinning her down and proceeded to fit the device. Firstly clamping the two waist band sections around her, then attached the crotch piece and finally securing it all together with a padlock. Kate was struggling throughout, but her struggles got weaker as she realised she was defeated.
"Why are you doing this, we should have talked about it first, it's not fair, I can't keep this fucking thing on all the time. Well you've got what you wanted, now let me up, I need a piss"
"Don't you dare talk to me like that" Mistress Sue grabbed one of Kate's nipples and twisted it viciously. "You piss when I say you can piss and you'll call me Mistress Sue from now on, understand?" she emphasised each statement with another painful twist of Kate's nipple.
Kate was taken aback by this, suddenly this wasn't a game any more, a knot formed in her stomach as she wondered what she had got herself into.
"P-Please Sue, that's enough, if you want me to wear this thing for a while then fine, now can you please untie me" she said trying to placate Mistress Sue.
Another twist "You don't learn do you bitch? Fail to address me properly again and I'll give you 20 strokes of the cane. The same cane you've used a hundred times on that little prick" She gestures vaguely in my direction. I'd been kneeling at the foot of the bed the whole time, terrified to move and fascinated by the way the situation has changed so suddenly and dramatically. "Now, try again" she says with another twist.
"P-Please untie me.........M-Mistress Sue" she says hesitantly, it's almost a whisper.
"No, not until you accept what's happening, I think you think this is still just a little game and we'll be back to normal later today, well it's not going to happen. I'll give you a little while for it to sink in, you've got until you've made me cum, and you better do a good job." Mistress Sue straddled Kate's head facing her feet. Immediately she nestled down, grinding Kate's face under her, searching out her tongue with her clit. Kate's nose was pushed hard between Mistress Sue's magnificent ass cheeks. Kate was just able to suck in air through her nose as Mistress Sue leant forward slightly, her nose was almost inside her asshole, She hadn't showered since yesterday and the aroma was pungent and overwhelming.
"Get on with it!" Kate felt her nipples being twisted painfully and snapped back to reality, remembering what she needed to do and quickly started probing for Mistress Sues clit with her tongue, she had licked her to orgasm many times and knew what she liked but never from this position. Despite the strangeness of the situation and her fear of what was to come she could feel her pussy getting wetter as she breathed in her scent, she was aching to touch herself already, their sessions had always ended in mutual pleasure and satisfaction, this time she had a feeling it was going to be different.
She probed and licked for all she was worth, all the time Mistress Sue was tormenting her nipples and grinding and wriggling on her face. Kate was getting more and more turned on as Mistress Sue approached her orgasm and her hips started bucking and gyrating in the air, her pussy feeling needy and neglected. Eventually Mistress Sue orgasmed violently and bounced on Kate's face for several seconds. The sight of this from my position at the foot of the bed was exquisite and I was nearly doubled over as my tortured cock strained and dripped inside it's cage, it had been so long since I'd felt the joy of release I could hardly remember what it felt like, my life was just filled with unending frustration, something that was unlikely to change any time soon.
"What's that matter slave" Mistress Sue said with a giggle, she had settled back onto Kate's face and was smothering her, She was looking directly at me, enjoying the obvious pain the incredibly erotic sight had caused.
"I'm sorry Mistress, I couldn't control myself, that was such a wonderful sight"
"I bet it was" She says, Kate is starting to struggle now as she's not able to breath underneath Mistress Sues huge enveloping ass. She casually reaches down and pins her struggling arms to the bed. After another minute she gets up off the bed, Kate gasps, her chest heaving and her face red as she can finally breath again.
"So, am I going to get any more attitude from you, or are you going to accept the new order of things around here?" Mistress Sue stares down into Kate's face.
"I-Ill accept it M-Mistress" Kate manages to say through gritted teeth, all she wants now is to be allowed up off the bed.
"OK then, I'll untie you, one bit of subordination from you and you'll get a caning, understand?"
"Yes Mistress" Kate says, defeated
Mistress Sue unties her wrists and leaves her to remove the spreader bar as she leaves the room. Kate sits on the side of the bed, slightly bewildered at the mornings events, not quite able to take in how suddenly her life has changed. Despite herself her pussy is soaking wet and aching, automatically she reaches down to finger her clit but her hand meets hard steel instead. She claws at it and tries to slide her fingers underneath it but it's much too tight for that. A feeling of intense frustration comes over her and she can feel her pussy juice running out from the sides of the belt and down her legs.
Suddenly she looks up and catches me smiling as I watch her impotent attempt to reach her pussy. "You'll fucking pay for that, now get on with your chores, you've got three hours to finish them, then I want you in the punishment room". Some things will never change.
