She woke up in the morning and with the vibrators still on. She couldn't get up and had to wait for Robert to come before she could do anything. She found herself so weak and she her orgasms all over the bed and realized she must have cum several times. The next one wan't too far either, as she started moaning again. She exploded her orgasms. She was hot and wet over and over again and she came three times more in two hours. "If I came four times in two hours, how many times should I have came the whole night?" she asked herself. Robert finally came in was smiling at her seeing all the cum in her body and the bed and she still moaning. He watched her cum again as he started laughing. She started to cry thinking about how humiliated and helpless she is in front of her younger brother. He then stopped the two dildos from vibrating and released the strap from her ankles. He pulled her by the arm and lifted her up and lead her to the bathroom. "Get into the tub and take a shower" he said. "My wrists are strapped, release them" she said. "No respect again huh?" he snorted. "Sorry Master. I keep forgetting. Please remove the strap please" she requested. "Well, you won't forget the respect after the training starts today!" he replied and she was stunned "What training....Ma-aster?" she asked slowly. "You'll know later about that. And now, I'll help you take a shower and you must be presentable for later!!" he said with a big smile on his face. "Presssennntabbble Master?" she asked with a shock. "Shut up now or you know what happens, don't you, Silvia?" he replied and a strong voice and she didn't dare to say another word. He opened the shower with absolutely cold water. She started shivering at the cold water and he also turned on the table fan in the bathroom so she would be just freezing. She was indeed freezing and tried to leave the tub but he stopped her from the attempt. "You don't disobey me ever again and this time, I'm really serious as your training period starts and no more tolerating misbehaviours" he said in a sharp tone which made he silent though she was freezing from the cold water. He filled the tub with cold water and turned the fan even faster. She was shivering and was dying to get out of it. He put his hand into the water and started massaging her from her breasts to her pussy and then her ass and penetrated her asshole. She was getting excited again but he didn't tease her for long and just soaped her and cleaned her from all the cum she had in her body. He let the water flow out and opened some new water. He turned the warm water on this time and removed her straps so she can help herself. She finally smiled a bit, being happy that she gets hot water but suddenly he spanked her in her ass with his hands so hard that she was taken aback by the stroke. She hung her head down knowing she had smiled and he noticed it. "Sorry, very sorry Master" she said facing down. "Good, take your shower now and out in 2 minutes, okay" he said and left the bathroom. She hurried her shower and came out exactly in two minutes so she doesn't have to disappoint her brother or rather her now Master. He was standing there waiting for her to come out. He pointed to the her dress. A red colour bikini, a sleeveless T-Shirt and a Mini-skirt. But before she reached her clothes, he asked her to stop. "I've to insert these dildos into you before you put your clothes on" he said and applied Vaseline and inserted both the first one into her pussy and the second one into her ass. She realized that this one was a bit bigger than the one yesterday and it looks totally different. The 6" dildos went as deep as it could into her and she was squirming for that. He then said "Wait, it's not over yet, still have the clamps!". She couldn't believe that she was going to have the clamps on again. She had no choice as he put the clamps on her nipples and twisted it hard so she was screaming the hell out again. She was then breathing heavily and slowed down after a while. "Okay, relaxed enough slut? Don't waste my time and put on your clothes now!" he shouted and she obeyed immediately. "Wear you socks and shoes, I can't help you do that" he said. "Are we going to go out??? With all these on me?? No, this can't be true!" she thought to herself. Robert stepped on her foot so she came back to her senses. "Thinking whether we are going out? You're damn right!!" he laughed. "Quick" he ordered and she was stunned and was staring at him. "Disobedience will not be tolerated and you know that, don't stare at me, understand?" he stammered. "Reply me, understand?" he asked again. "Yes Master" she said as tears started coming out of he eyes. She put on her socks and tied her shoe laces and they left the house.

They reach their car and Robert puts the straps on her ankles and puts her hands crossed behind her and straps them as well. He didn't want her to make any noise so he gagged her mouth with the dildo he used yesterday on her. She is sitting in the front beside him and he is driving. The area is a suburban area and there is almost no chance of anyone spotting her in this state. She looks at him in anticipation of knowing where they are going but he surely doesn't want to tell her yet. They have been driving for 30 minutes now and she didn't know where he was going. Suddenly, the vibrators of the dildo in her body started. She was stunned and wondered how they started. She started moving involuntaryily. She looked at Robert and Robert was laughing. "How is the sudden sensation in your asshole and pussy my dear?" he laughed asking her. "See this, this is what is called a remote control, and it controls yout dildos!" he surprised her. After a while, she was moaning and he stopped the vibrator when her moans were really loud. "Wet and hot already? Long way to go" he said with a smile. "It's about 11.45am and will be there in 30 minutes" he said as she was looking on. After 10 minutes, he pulling the clamps beneath her clothes. She wiggled and tried to shout loud at him and put up a stare at him in frustration. "No good, little girl. Just earning yourself some tough time" he said and laughed and showed her the remote in her face and turned it on again. She was squirming against the seat and pleaded with her face to turn it off but he wouldn't until she moaned again. She was squirming and moaning louder and louder. He started pulling the clamps to make her scream as well. When he thought she was reaching her climax, he turned off the vibrator! She just can't resist it and after so many orgasms the previous night, she was just wanting more and couldn't wait to cum. She knew that he wouldn't let her cum until very late just like the previous day. When they almost reached, Robert reached for the blindfold and blinded her. He removed the dildo in the mouth though so she can talk. "Furious that you don't know where you are going?" he laughed. "Please remove the blindfold, Master. I can't take this without knowing where I'm heading to. Please!" she pleaded. "It's for me to decide and your request is dismissed" he said as he opened the door to get off. "Where are you going, Master?" she asked. There was no replt because he was already gone. He went into the house and rang the door bell. Ricky answered the door and said "So you are already here, where is your sister?" he questioned. "She's in the car and where are your sisters?" Robert said. "Tied up in the room" he said and told Robert that Melissa and Andrea don't know that someone's coming home. Robert replied saying that Silvia also doesn't know about us coming here. Well their parents are gone on a vacation and Ricky and Melissa are alone with Ricky asked to be incharge. Ricky's parents are no different from Robert's and furthermore, Robert and Ricky are classmates while, Melissa and Silvia are classmates. Andrea was one year younger than Melissa and one older than Ricky. Robert went to get Silvia while Ricky went upstairs. Robert brought Silvia into the house but before that, he put the dildo back in her mouth. "If you disobey me here, you will have hell to pay, understand?" he said it very strongly in her ears and she nodded. She was excited but didn't know where she was.
