We spent a few quiet and calm days. One would expect that she'd have been eager to keep the pressure on, to rub salt into the wound. Instead, it all went normal, at work and even a few evenings out together, until she invited me to her place. Even though we did some crazy stuff, we've never actually met at my or her house. I couldn't help but feel excited at the idea; part of knew that it could have been really painful for me, but I already accepted that and to be honest, I was hoping for it. The day came and to my surprise, and a tip of disappointment, she didn't have any strange behaviour during the day. It was a perfectly quiet and calm day as the few before that. Even the time from workplace to her house wasn't something different than two friends talking and having fun, and after a while she said to find a place where to leave the car. We walked and couple of minutes and we were at her place, a block of apartments in style with the ones around. We took the elevator and she was still talking about a story of her and her friends; I tried to partecipate and to be interested while, deep inside, I was still waiting for her to do a move. She let me in the house, and followed me closing the door behind and as soon as she did that, it was like the day turned to night all of sudden. "Naked and on your knees at the center of that room. I'll join you when i put something more comfortable on" I was waiting for it, but it was so sudden that it hit me hard. I was still trying to understand if she was serious or not when she went to what had to be her bedroom without even looking at me. I was there for that, and I couldn't do anything but do as she asked. I started undressing, a bit nervous: I was willing but still insecure. Feeling defenseless with her was a fulfilling feeling, but at the same time it made uneasy. There I was, naked, on my knees and waiting for her to do whatever she wanted. The wait was killing me, and I started having chills through my spine trying to figure out what she was about to do to me. Suddenly I heard the door of her room opening, and the sound of her heels closer and closer. "Turn around, don't look at me" I complied, turning my back to her and as soon as I did that I heard her enter the room. The sound of her heels was closer and closer and I was reacting to that; I felt a rush of discomforture noticing how that feeling was visible building-up cock. I soon felt her right behind me; I kept my breath while I felt her reaching for my hands and tying them up together. I tried to force the know without and her noticing and I found out that she actually did a good job. Soon after, she closed something around my neck and attached something to it, and then finally positioned herself in front of me. I missed a few heartbeats the moment I saw her. She was wearing black knee boots with a decent sized heel, her bra and her panties only. The sight of that nearly killed me: My head was so light that I thought I was falling down and I could hear my heartbeats right in my temples, how hard my heart was pounding and, worst of it, my cock was soon all loaded up. Everything right in front of her, with my hands tied behind the back. She knew that I was starting like her, to want her, and she was making me pay for it. I barely raised my head to look at her face, and I saw in her eyes that she knew what I was feeling, how hard it was for me and she started speaking with a sadistic grin. "Rule number one: Don't dare to touch me without my permission. Not even by mistake." That hit the spot, evil bastard, I thought. Show me what I could have, and then deny me that. I nodded, unwillingly, my body full with hatred and love for her. "Never forget that. I'll make you scream for that permission.. and the more you need it, the more I'll make it humiliating and painful for you." She knew how to make me feel miserable, that's for sure. My cock was so hard by then, that it started to ache and the more I try to hide it or make her look another way the more she seemed to notice. "Look at your cock.. poor Mark.. pity that it will stay unsatisfied for God knows how.." with that said, she moved away and only then I noticed she was holding tight a leash tied to the collar on my neck. The sudden push made me fall over, even flattening my cock in the process and I was still in pain when she sighed irritated. "It's the old collar and the old leash of my parents' dog.. they suit you, don't you think? Now, on your knees again and follow me" I could feel tears in my eyes, trying to put myself on my knees again with the hands tied like that was so humiliating that I wanted to cry. She went for the couch and I started follow her on my knees trying to keep up and not to fall over. Once there, she changed the path and I quickly realized she was just making me go in circles around the room. After a while, she turned and went on to pull me around walking backwards. It was too humiliating for me even raising my face and looking at her. She did everything in her power to make everything unbearable for me, obviously. She kept looking at me every step, every moan, every fatigue face trying to keep up with her, laughing, asking me if I was realizing how ridicoulous I was. I quickly lost the count of how long she kept me doing that before she decided to stop. "Now now.. Do you still want me after I've done that to you, doggy?" She had a bold look in her eyes. She knew the answer, she was so full of herself that I wanted to tell her that I didn't, that she didn't deserve that. But I did, I was dying to have her. My body and my mind were completely hers in that moment. I nodded slowly, feeling an overwhelming humiliation for that. "You're so cute.. if you beg me enough, I could let you kiss my legs" And i did. I begged like I've never done before, I was feeling tears in the eyes how much I wanted it. I craved it. She was just toying with me, keeping me doing it because it was never enough. She asked me to bark, to behave like a dog, and then kept telling me that it was still not enough. Finally, distractedly and unheartily she told that, after all, she would have granted me that, but I had to reach her on all fours. I complied, and to be honest I did it with joy. Despite the humiliation I was able to kiss her, and I desired her so much that I didn't want anything else in that moment. The more a was getting closer, the more she was making steps backwards but I didn't expect anything less and finally I was at her feet. "Very well.. on your knees and have your prize.. but touch me anywhere other than the legs and you'll be punished" I moved my lips closing to her leg, closing my eyes anticipating her skin but at the very last moment she moved it backwards, and after a couple of seconds she moved it again in a more fearful way. She kicked my hard cock with the tip of the boot so hard that I felt my life taken away. Without knowing it I was bent on myself, with the forehead touching the floor. I was trying to breath, but the pain was crippling my body. "Ooopsie.. does it hurt?" The mockery tone of her voice drove me wild for a moment. It was a pain like I've never felt before and she was making fun of me. I was about to ask her to stop, to release me and let me go for good. She moved a few steps backwards, looking at me serious and cold as if she knew what I was thinking. "You want to quit? Fine.. but don't ask me something like this till you die. Don't hope to lay a finger on me too,for that matter" That was what I wanted, but hearing her saying it like that made me feel like I was about to die. ".. or i'll make you taste feelings you've never felt before. It will be hard, painful and humiliating. And you will love it, every second of it. You'll learn to beg me to be my slave and..well.. don't hope to lay a finger on me nonetheless" She smiled making that last remark, and the look of eyes warmed my heart despite the situation I was in. "I'll be... your.. slave.." I could see in her eyes that those words gave her a rush of sadism. That gaze was so inspiring that only looking at her made me feel all the pain that she was making me experience in her mind. Little I knew at that time how far that oath would have taken me. "Will you? I hope you can stay true to those words.. For the matter at hands, I wanted to give kick you five times so you still deserve no less that four kicks" ".. F..fine.." I didn't how to handle that, to be honest, but I was willing to try for her. I was so much in her power that I didn't want to let her down in any way. I barely finished to speak that she hit my cock so hard that I felt my lungs taken out; I resisted the first one this time, probably because I expected that, and she followed up with a second and a third without pause, and after that I fell on all fours, breathing hard. "God.. I want to break you so much now.. do you want to be my slave? Very well.. we'll make it ten then. Ten kicks to your hard cock that will probably never feel anything other than pain. And we start all over.." My body was shaking violently, every fiber of my body was telling me to react, to run, to walk through that door and never think about her again. I put myself in position again, waiting for her to break me, as she put it, and looking at me ready and willing she started biting her lips, barely managing the sadism she had inside. She reached me like possessed and started kicking with all the might she had in her body.
