Aly quickly got into dominating Karen. For such a submissive girl, she adapted to being domineering amazingly well, and as soon as she came down from her bubble bath she made a start by saying to Karen "I'm desperate to pee, lie your head back on that stool, so I can pee in your mouth."
Karen looked at me, but I just stared into her eyes, and Aly snapped, "Do it!" Which startled Karen into obeying her new mistress. This was going to be fun.
Aly squatted down over Karen's face and settled her weight onto Karen's open mouth. She smiled at me as her piss flowed into Karen's mouth, saying, "I could get used to this, her mouth is so lovely and warm, and toilets are so cold and clinical," then, "I've finished, but I'm so comfy here I think I'll stay here for a while, do you think she can breathe?"
"Possibly not," I replied, "but I'm sure she'll make a fuss if she can't," and then Karen was making a fuss, wriggling and trying to push Aly off her.
Finally, Aly lifted up a little.
"Lick me clean," after which Aly flopped onto the sofa next to me and pointed between her legs for Karen's benefit.
Karen got the message and crawled between Aly's legs and began licking, which Aly loved.
We settled down to watch a movie with Karen alternately licking Aly's slit and giving me a blow job. After about an hour Karen lifted her head from Aly's pussy to ask to go to the loo.
"No!" barked Aly, "you can wait until you've made me cum again, and later I'm going to punish you for not calling me mistress."
Karen went back between Aly's legs and licked like crazy, but since Aly had already cum several times, it took quite a while to get her over the edge again. Once she did get there, however, it was obviously a really good orgasm, and as she reached the peak she grabbed Karen's long blonde hair and pulled her tight in to her pussy, so that Aly could clamp her legs tight around Karen's head. Aly kept her there until her climax was totally over, then pulled Karen up by her hair and said, "Now you can pee, come with me."
Aly stood up, pulling Karen up by her hair and then dragged her to the door.
"Go and do it in the garden," she instructed.
"But I'm naked," wailed Karen, "someone might see me."
"Don't you dare disobey me!" Aly shouted, giving Karen a hard shove through the door.
Karen stumbled across the hall and crashed into the lift doors, just as Aly slammed the door shut behind her. Now Karen had no choice but to take the lift down and go into the garden to squat and pee. Aly watched through the spy hole in the door.
"She's in the lift," she told me, "sadly there was no-one in there already, but hopefully someone will get in on the way down."
Aly next went to the window, but couldn't see anything in the dark.
After only a few minutes Karen was back, knocking on the door. Aly left her quite a while, then went and opened the door, but kept Karen outside.
"Please may I come in mistress?" she pleaded.
"When you've told me exactly what happened, did you meet anyone?"
"Yes!" Karen confessed "two young guys got in the lift with me, they kept touching me and kissing me, I thought they were going to rape me, but the doors opened and I got out."
"What a shame they didn't," Aly smirked, "we'll have to arrange a consolation prize for you."
Aly aloud Karen in and closed the door behind her and shoved Karen to her knees again, pointing between her legs for Karen to resume licking.
"Are you horny darling?" Aly asked me whilst stroking my cock through my trousers, "why don't you give Karen's tight arse a good reaming?"
"Brilliant idea!" I exclaimed, as I walked to get the lube from the drawer. I quickly dropped my trousers and briefs , put some lube on the head of my ever ready penis, positioned myself at Karen's small brown opening, and thrust in hard.
"Mmmnnff." Karen exclaimed in shock.
"That felt nice darling, keep ramming her."
So I did. I pounded her lovely tight arse for a full five minutes, but it felt so good that I couldn't go on much longer.
"I'm going to cum babe," I called.
"So am I!" Aly shouted back, "Aaaarrhh!" Karen cried.
"That was totally wonderful, " I told Aly, "I think I'm going to use her arse a lot in future."
"Well, she's a lucky girl then...what do you say slave?" she demanded of Karen, but
Karen just looked defeated.
The next evening over dinner Aly explained to me that she wanted to torture Karen, in a sexy way, of course, and she thought she would start by stretching her pussy, then her arse, and then maybe attack her nipples. I told her that I thought that would be brilliant entertainment.
"Karen, when you've finished loading the dishwasher come in here, Aly is going to play with you this evening." I instructed.
Karen went very pale.
"Oh God, please don't hurt me, I don't mind being your slave, but I still hurt from the Wooden Pony, and my arse is still sore from being fucked."
"Shut up slave, you lost so you don't get to choose." Aly explained, with venom in her voice.
Karen was naked as normal, but I had allowed Aly some clothes for her week of dominance over Karen. She had a very short flared skirt on, and a thin T shirt through which I could see her erect nipples. No underwear, of course.
"So David, I'm going to use the Pony, but in a different way. I've decided to Stretch Karen's pussy by inserting bigger and bigger objects up her. It should be fun, but I hope this room is as sound proof as you say it is."
"It doesn't matter Aly, the neighbours above and below are away on holiday."
"Oh good, I'm looking forward to the screaming." Aly announced, grinning broadly.
Aly led Karen to the pony, and made her get onto it and be attached by her arms as usual.
"Right Karen, stand on tip toes while I position this dildo."
Aly locked the dildo into position pressed hard against Karen's unenthusiastic pussy. It was the fattest dildo I'd ever seen, at least twice my thickness, and I'm not small.
"Ok, well I don't want to waste time at this early stage, so David, let's you and I go and encourage Karen down onto the fake cock."
The dildo was smothered with lubricant, so when we pushed gently on Karen's shoulders it slipped easily between her pussy lips eliciting a shriek from Karen. It was two or three inches inside Karen's vagina, which she obviously found uncomfortable, but she wasn't in agony. That was until we both put all of our combined weight onto her shoulders, her knees buckled under the strain, and she slid inexorably down the dildo. It was about ten inches long and it only took a few seconds to be fully embedded inside her sex, making her scream and scream.
Aly picked up a couple of belts which she had placed close to hand. She pulled Karen's Left foot up, and strapped her leg bent double, then repeated the process with the right leg.
"Ok," she said, "all of her weight is now resting on the entrance to her cervix, I want to get the dildo past the entrance and inside. I need you to help me, we're going to stand on a leg each."
We hopped on to Karen and her cervix quickly gave up the uneven contest, and we felt ourselves slowly lowering until Karen's knees almost touched the floor, almost but not quite.
"Ok, I'm happy with that position, let's go and watch TV for a while, would you like a whisky?"
"I'd love one, but I think we should gag her, she's making one hell of a noise." I suggested.
In the end we watched TV for nearly two hours, and when we went back to Karen she had passed out. She had also wet her self, so there was a pool of pee on the floor underneath her.
Aly and I unattached Karen, removed the dildo, then used smelling salts to wake her.
Unfortunately sorting her out meant that she got rolled around in the pool of pee, so that she ended up covered in her own urine.
"Karen, you filthy bitch, there's pee all over the floor, get on your hands and knees and lick it all up. I'm going to lock you in here tonight, you can sleep on the floor, goodnight, sleep well." Aly announced.
"Well, you certainly know how to torture a lady." I commented, as we headed to bed.
"I've got another great idea for tomorrow. Do you want to fuck my arse now?"
"That's a great idea, I love your tight arse."
Shortly after the week of Aly tormenting Karen I decided it was time to do something about Peter. In my first plan for Peter and Karen, she was living with him, in her house, and controlling his sex life with the key she was wearing around her neck, which would unlock his chastity cage, when she thought it appropriate.
Since then, I had removed her from her own house, to be my slave, under the control of my Senior Slave, Aly.
This was all fine, but it left Peter in Karen's house, on his own, free to do as he wanted, with the exception of sex, as Karen still held the key. Since he now had no access to Karen, or her to him, he was permanently chaste.
This situation had obviously been playing on Peter's mind, because, before I could do anything about him, he rang me.
"Rob, you've got to help me, I'm desperate!"
"I imagine you are, how long is it since you had an orgasm?" I actually knew, but thought it would be fun to tease him.
"Over three weeks!!" Not actually accurate, but I let it slide.
"Well, Peter, I guess we need to find a way to help you, why don't we have dinner tomorrow evening, and we can discuss a way out of your predicament."
"That would be brilliant!" he exclaimed, clearly not understanding what I had in mind.
The next evening after work, Peter and I met at a Brazilian restaurant in Fulham. We exchanged pleasantries while were sat down, chose some wine, collected some salad from the salad bar, and started eating.
