So, as the months continued, I received punishment and humiliation for my mistakes and also for my unworthiness. I concentrated totally on learning everything as fast as I could, not for me, but to let my Mistress be proud of her slave slut. At times I would cry in pain or scream for joy. An unspoken agreement between us was that weekends were for slavery, the rest of the week I would go about my everyday life.
Having such a satisfactory relationship made me feel better and, therefore, I was able to concentrate more on my life, which resulted in a better efficiency at work and soon I had an increase in my wages and a little promotion.
The weekend after my promotion at work Mistress Serena brought me a double strap on dildo, with an eight inch main and a five inch for ass so that I could be fucked at the same time. I had never had anal fucking before, so I was quite concerned, especially by the size.
We started fondling each other and then she lay back, letting me make her cum. She knew one of the infallible ways to turn me on was to let me see her cum and taste her. My pussy was by then soaking wet, so she ordered me on all fours, and then started to lick my pussy and then my butthole. As she started to finger fuck me, my clit tingled and my juices were dripping down my thighs - I was about to cum when she stopped.
A loud moan erupted from my throat, but I quickly stopped, when I realized I could have been punished for that. That thought made me even wetter. She put some lube between my ass cheeks and then, with a couple of fingers, fondled my pussy lips, while with the other hand started probing a finger inside my butt hole. The arousal and the lube did their job and I felt a new shudder from my ass all through my body.
My concern faded as the insertion of the second finger into my ass almost made me cum. Now I was completely relaxed, looking forward to being double fucked as she put the strap-on and fastened it around her waist. Then she inserted the bigger dildo into my pussy, I had never had something so big in there before, but it wasn't a problem. I hoped that I would one day, and now, with a person that I knew would never hurt me, I was more than eager to try.
Slowly sliding it inside me my pussy was completely stretched, and then she started to move back and forth inside me, always stopping before I could cum. After a little while, she put the cap of the second dildo on my back entrance, and slowly pushed it inside. As soon as the tip was inside me she stopped. Making sure that I was alright and enjoying it she started again to push. I pushed too and in a second I had both of the dildos completely inside me. Knowing that I was about to cum at any time, I asked permission from her.
She said to resist if I could, and then started thrusting the dildos harder and harder into me. I managed to resist five or six more thrusts then, for the first time in my life, I squirted. Screaming aloud in pleasure and repeating her name with my eyes full of tears of joy. The load of cum flooded the carpet and our legs and then I collapsed and fell on the floor, completely worn out.
As soon as my legs stopped shaking, I fell asleep, and then she woke me up with a slap on my butt cheek. I jumped up into the right position as I had forgotten that I deserved a punishment. She struck my ass at least twenty times, feeling my arousal at the beginning and then my tears and pain after the fifteenth slap.
That was enough for the day and I didn't even have enough energy left to move onto the bed, so as I lay on the floor, I held my arms around my knees and stopped moving. I had been barely aware that she took me in her arms, put me onto the bed, and then she lay next to me with her arms around me and fell asleep. My last thought was how complete I felt.
Weeks passed by and Mistress Serena decided to test my training. As I arrived home one Friday evening I found a package on the living room table. Taking it into the bedroom I unpacked it and inside there was an envelope, which I opened and read the message.
I had to make sure that I was completely shaved, and dress with what was in the package, put my hair in a braid, and use a fire red lipstick on my lips. The items I had to wear were short heeled black shoes with a lace around the ankle, fishnet stockings, no underpants, a black leather miniskirt, a black leather corset which pushed my boobs high - leaving my nipples uncovered - and a black short cloak which reached down to my waist.
The slave collar was a thick leather strip, with seven D rings all around it. In the package there was also a chain leash to attach to the collar and two leather wristbands, with two metal D rings on each. The following item was to be worn once we had arrived at our destination.
It was a black leather mask which covered the whole of my head, with only holes for my nose and my mouth. I was aware this mask was another sign of my Mistress caring for me, as it was needed to keep my identity unknown in case we met someone I would need to work with. As always everything fitted my body measurements perfectly.
I had to be ready at 22.00, sitting on the edge of the couch in the living room, offering the leash, already bound to the collar, to her upon her arrival. She arrived exactly on time, her outfit hidden by a long black cloak, and ordered me to stand still while she inspected my outfit.
Suddenly two fingers probed my pussy without any hint, and I winced, with a little squeal. Staring at me with a stern look I knew that a punishment session was added. Taking the mask and putting it in her purse, she wrapped the short cloak around me and then started controlling me with the leash. Once satisfied by my responsiveness, she took me out to her black SUV, placed a blindfold on me and we set off on our journey.
It took just over an hour to arrive and I heard her murmur something to someone, the SUV moved again then parked in a closed place. She got out, and I heard her remove her cloak, then she walked around the SUV and opened my door. Removing my blindfold she gave me the mask, then removed my own cloak. The outfit that she was wearing was amazing.
It was a full length leather skin-tight suit, with hidden straps to remove single pieces at will, leaving little to the imagination of her luscious body. Her curly red hair was loose on her shoulders, her blue piercing eyes were shining, and her appearance was oozing with extreme power. I felt the pride of belonging to such a powerful Mistress.
She led me past a security door, along a corridor and through to a wide room which was stuffed full of couches, thick carpets and low turrets full of metal rings, which I could understand the use of at my first glance in the room. There were four or five slaves of both sex chained to the rings – some loosely and some tightly.
As she sat on a couch she linked me up to a turret. We both knew that wasn't necessary as I was submissive enough, but it was a public show of her power over me. She made small talk with some of the other masters, and then she started to give head to one of them. I couldn't take my eyes from them and I noticed that in a few minutes he put his head back and started to moan.
Then he tried to put his hand on her head, she stopped and with a stern look, put it down on the couch. It seemed to be enough for him to avoid further uncertainty, so they both focussed on her mouth work as she deep throated him.
