This will make a lot more sense if you read EternalRoomies first.
I knelt in position as soon as I heard the locking mechanism start to disengage. Mistress was coming in.
I had learnt many things since I had become her slave. I had learnt there was no hope of escape, even if I had wanted to. That I really was hers. I was sure I would die in her chains, and even though she felt nothing for me at all, I was completely in love with her.
She controlled me in every way. Mistress was merciless, cruel and sadistic. She was also curious about nearly every aspect of the human condition. Especially, it seemed, with anything to do with pain and suffering. So many facets of humanity, with her being a psychopath, she did not fully understand.
One day, she had asked me how I felt about her. Learning early on never to lie to my owner, I told her I loathed and hated her. Her response had both baffled and surprised me.
"Okay slave, let's see if I can make you love me."
At the time, three years ago now, I thought her a fool. How could I ever love the person who tortured, tormented and molested me? Now, though, my quim dripped at the sight of my Mistress, my owner, my love. I craved to please her. Sobbed when she scolded and grew giddy on her praise.
So as the locks disengaged I strived to kneel perfectly as I had been trained. I felt my pussy moisten in anticipation of her presence and my face flushed with a huge smile for my love.
As the heavy door swung wide I saw two people framed in the aperture.
One was my owner dressed, unusually, as a dominatrix. A black latex catsuit clung to her beautiful figure. Thigh-high patent leather boots sheathed her legs. Cruel steel spikes served as heels that looked to be five inches high. Long glossy rubber gloves clad her slender arms and her thick lustrous mane of hair was pulled back into a severe high ponytail. Mistress looked magnificent.
The other figure could not have contrasted more. A slim petite girl with ash blonde hair stood nude, gagged, leashed, blindfolded and bound next to my owner. A steel collar, to match my own, gripped her throat tight. Heavy steel chains linked fetters that matched mine too. The girl shivered in fear or arousal, I could not tell which. Mistress had taken another?
"I've brought you a present, Slut," declared Mistress. Slut was the name Mistress had rewarded me with the day I confessed my love for her.
"I need to study interactions now so I've got you a roomie for your cage. Slut meet Slave, Slave meet Slut. You two will be besties from now on. Lovers in due course. Slave, I'm sure this is all a bit of a shock. But Slut will fill you in on the details. I'm afraid I'm not going to be honouring that safe word, my dear. Nor will you ever be free of those chains again. Still, you enjoy bondage, just like your new roomie, Slut. Plus I'm enjoying this outfit you bought for me. I like how I look, and the effect it has on you, as well as the look it produced from Slut just now. So I'm sure I'll dress in it again... if you are good."
Mistress opened the door to the cage and manhandled the cowering girl into the cramped space with me. Locking her chain leash to the roof of the cage next to mine she slammed the cage door shut and stood over us.
"There are so many things I can do with two that I couldn't do before. This is going to be so much fun. Now girl's, you be good while I go dispose of slave's car and possessions. Then when I get back we can introduce you two to each other properly."
Mistress turned and shut the door to the cell. The lights went out and we were plunged into total darkness. The girl squirmed and I felt a hand grip mine. I squeezed it gently and quiet sobs escaped her gag.
I had a new roomie.
