Robert smiled at Silvia and said "So, I am incharge here, huh? Well you are in my control and better follow what I tell you or you know what will happen". Silvia was surprised at what he said and asked "What do you mean by that?" 'You know what I mean don't you slut!!' She was just stunned and before she responded, Robert just stared in her eyes. She knew she can't do anything and just put her head down in embarrassment. "So we have two months to spend and you have a lot to learn little girl" he said smiling. "You shall address me as Master from now on and not say a word till I ask you, understand slut?". "Yes Master" came the answer. She was so embarrassed that her face turned bright red. "Let's get started now" he said as he dragged her to the sofa. "Kneel down and face the sofa" he said. She hesitated but did so without complaining. She was still wearing her usual bikini. He took a scarf from her mother's closet and blindfolded her. "What are you doing?" she questioned with authority. "Shut up. Didn't I tell you not to talk. You are allowed this time but once more and you know what..." He tied the scarf round her eyes so that she can't see anything at all. "You stay still till I come back, understand?" She nodded her head and he walked away. She was excited to be controlled as she wanted to be submissive but being submissive to her own younger brother made her sad and embarrassed. She waited there for what seemed to be hours. After 25 minutes he returned with a few straps and told her to put her hands behind her back. She knew he was going to tie her hands so she said "You can't tie me" in a very loud voice. He pulled her hands back with force and put the straps on. Then he pulled her ankles together and strapped them as well. She struggled but he was just too strong for her. "You just disobeyed me and you know what is going to happen, surprise!" He said and dragged her to the dining room. He put her on the dining table and roped her to the table. He turned the lights brighter and turned off the air-conditioners so the room gets warmer. She kept struggling but knew that complaining would only make things worse so she kept the thoughts to herself. She heard him walk out and shut the door. "How long will this be and I'm already feeling so hot" she thought. But he returned moments later and slid a cold metal in between her breasts. A second later, her breasts popped out and he then slid it near her pussy and her panties tore as well. Yes, he used a pair of scissors. "What the hell do you think you are doing? I'm your sister and don't want to do this to me" she shouted in anger. "HAHA, you are so sweet in this state and well, it's all dad's idea!" "You also had disobeyed me by shouting and you will receive additional punishment for that as well". He took the bra and panties off the table and went away shutting the door. She was naked, totally bound and blindfolded. The room is getting warmer and warmer with the light intensity and she's getting hotter and hotter. After about 30 minutes, the door opened again and Robery walked in to see his sister already sweating. He smiles at her and puts a soft thing on her and moves it all over her. She feels ticklish and moves involuntaryily with her hips moving up and down. He teases her with that for the next five minutes and she says "Please, I beg you, this is enough, I can't take it anymore. Please let me go. Please!" she pleads. "Well, you know that you are not going to get anywhere with your pleads and you also know that by talking you are disobeying your Master, Sylvia" came the reply. She thinks to herself why did she talk as he roams around her body with the soft stuff. She starts squirming and moaning. Her pussy is really wet now and her juices just dripping. "Wet already?" he laughing asked. Her faced turned so red and she was blushing. He stopped teasing her and and asked her what was that made you so wet as if he didn't know. "The-the soft stuff, what is it?" she asked quietly. "Make a guess" "I don't know" she said. "It's a feather my dear, a simple feather" he said. "If you co-operate, you can enjoy the whole thing but if you disobey, it will only be me who enjoys the whole thing". "Let's set some rules now". "You shall call me only as Master or Sir, then you can only talk when I ask you something, you can't scream or shout or ask me anything, but you can squirm and moan. You shall obey to whatever I say or you will be punished mercilessly. Are we clear Silvia?" "Yes Master" she replied. "That's good". He then took off he blindfold and looked at her smiling. She was so embarrassed to see her younger brother doing all this to her and blushed. She turned away from him. "Look at me Silvia" he said loudly. She hesitantly turned back towards him. "What? Are you so frustrated that you are in this position with your younger brother in total control of you? Embarressed?" he asked her in a teasing tone. "Yes" she whispered. "YES what??" he slapped he breast and asked. "Yes, Yes Master" she said. "Maybe because you don't what I can do to you, so you are failing to obey" he said in a sharp tone. He then touched her breast with both hands and squeezed them hard. She screamed in pain. "No screaming, and you know that" he laughed. "Yes Master" she said without a choice. He squeezed it harder and harder and she was moaning again. She was already sweating of the warm room and wet by the humiliation she had from her brother and the feather. She was moaning louder and louder and he realized that she was going to cum soon. So he stopped and stared at her. She couldn't help but look at him helplessly. He pinched her nipples softly and asked her if she liked it. "Yes Master" she said. He pinched it harder and asked if she liked this one too. "Yes Master" she said again but with more enthusiasm. So he kept pinching it more and more harder everytime and after a while, she was moaning again. "You know you are moaning in front of your younger brother, do you realize that?" he asked smiling and staring at her in the eyes. She looked him and said nothing but "Yes Master" a midst of her moaning. Her moaning came louder and louder. He stopped when she was about to cum. "Feeling very hot huh? You're pussy is so wet and the juices are dripping very badly. Do you want to cum, Sylvia?" he asked her sweetly. Being so embarrassed that she can't control her senses, she said "Yes Master". "You need to ask much better, Sylvia" he said. "Please let me cum Robert, I can't stand this anymore. Please! Let me cum, please!!" she begged. "What? Robert? You are such a bad girl and don't even know how to make a request" he said sadistically. "Sorry, Master. I didn't mean it. Please let me cum Master. I beg you. I can't resist my senses anymore" she pleaded. "I'll be right back and wait for me, Sylvia" he said and walked away. She was naked and helpless on the dining table, sweating and juices dripping from her pussy. She wanted to cum so badly but she couldn't. She waited and waited. It was getting so warm that she was burning hot and was ready to cum when she senses something on her pussy. He finally returned with a bag and it seemed quite heavy. She wondered what was inside and was trying to guess but couldn't figure out. "Want to know what's inside?" he asked calmly. "Surely Master". "No way sweetie" he said and put the blindfold back on. She was excited but also wondering what was coming next. She heard him open the bag but of course couldn't see what he took out. He took out a pair of nipple clamps and said "Guess what is coming next" and attached the clamps on her nipple. She shouted in pain. "Don't do this. It hurts. Remove it now" she screamed. "Where is all the respect gone little lady? You shall pay for talking and disrespecting me". Then he added some more clamps to her breast. "Don't you dare disobey me again, Silvia" he said pulling the clamps and making her scream in pain. She had never tried this before and now she realizes how much it hurts. She was moaning a midst of the screaming. "Now, I let you cum but your pubic hair will get wet. So, I think I'll shave it for you" he remarked. "Dammit, no way you're going to do that to me" she said. There was no reply. Suddenly realizing that she just disobeyed him, she said "I'm very sorry Master. I didn't really want to disobey you. Please forgive me. Please" she pleaded again. "Good that you realize that you disobeyed me but you are not sorry yet. You will be soon!" he said. "You won't cum for now and I'll make that sure." He removed the clamps and she slowly stopped moaning. Now her nipples were really sore and she was still dripping. He took the shaving cream and the shaving stick from the bag. She didn't know what was coming. First he took a towel and wiped the juices from her wet pussy. He then spread the cream on her now dry pussy. She tried to stop him by pleading again but to no avail. It just made her realize that she shouldn't have said it at all. He started shaving her pussy and the hair dropping with the cream. She started moaning again and knew her climax was near. He did the shaving little by little ensuring that she doesn't cum. He finished shaving her clean and she didn't cum but moaning loud and at the edge of the climax. He sprayed some after shave on her pussy and cleaned the mess. He waited some 10 minutes silently and made her wonder whether he was still there. She was sweating like anything and was dripping all over again. She was excited but wanted to cum so badly now. "Are you there?" she asked. There was no reply from him. She thought he probably had gone and started to try to free her straps. "You dare do that" he said stunning her. "Sorry Master, I thought you had gone" she replied. "Well it is 7.00 pm already and I have to go out now. You better stay where you are and try not to move. I've put a burning candle next to your legs and you dare move" he said though there were no candles at all. "Remove the candles, it might burn me" she yelled. "Unless you move, you won't be burnt. Understand?" "Yes Master, but.."she started but didn't say anthing further knowing it won't help. "I'll only be back late in the night but you shouldn't be sleeping till then, so I'm going to put the clamps on your nipples back on and guess what else I am going to do" he said. He attached the clamps to her already sore nipples and she was screaming once again. He twisted the clamps so it really hurts her. She was screaming overwhelmingly. He then took another two clamps from the bag. Holding them in his hands, he untied the ropes and lifted her up from the table. He made her stand against the wall and put a chain around her neck and hooked it to the nail in the wall. Her wrists and ankles are already strapped and she has no chance to move unless she want to cause pain to her neck. He didn't want her to shout so he took the towel that he used for wiping her pussy earlier and wiped her pussy which was dripping again dry, and stuck it in her mouth. She was screaming behind the towel but the sound was low. "One more final thing before I leave" he said attaching the two clamps to her pussy. She just couldn't bear it and screamed so loud but the towel lowered the sound very well. "Candles are right near your feet, so don't move even a bit " He said as he left the room turning off the lights and shutting the door. He didn't turn the air-conditioner on, so it was still very warm in this hot summer. She stand there totally naked, pussy shaved, blindfolded, gagged by the towel with her own juice, neck chained to the hook above her and clamps in her nipples, breasts and her pussy. She didn't dare to move an inch as she was scared of the candles. She couldn't believe she was in this state the same day her parents had left and was so humiliated by her own younger brother.
