All four came to the room where Melissa was helplessly tied and totally naked. She felt embarrassed that only she was naked and the others were totally dressed up. "Andrea, get the 2 Riding Corps" said Ricky. Andrea did that. "One for you and one for Silvia. 100 on Melissa's nipples. Okay?" Robert asked. "Yes Master" responded Andrea looking at Melissa. Robert took a dildo, 2 nipple clamps and an iron ball and went to Melissa. He used some Vaseline on the dildo and slowly inserted into Meliisa softly. Then, he put the ball inside her pussy and taped it. Then came the tough part. He attached the clamps on her nipples and Melissa was already screaming. "Screaming already? It's not even started yet" Ricky said as Robert took the weights and slowly hung it to her clamps. Melissa was surely in pain and was screaming louder. Robert was not done yet and tapped the weight and it swung front and back creating more pain. Ricky got the leather strap and hand the cane to Robert. "She's ready" said Robert as he landed the first shot on her ass. Ricky landed his first shot on her pussy as well. Silvia and Andrea knew how bad Melissa was feeling but were happy that they are not the ones who are being punished. Looking at this, the girls got hot and felt the moist in their cunt. "Okay start both of you. You must land the shot hitting her nipple and shaking the weights as hard as you can. If we find you are not doing your best, it will be you being hurt. Are we clear?" asked Ricky "Yes Master" answered the girls and landed their shots as commanded and Melissa was in terrible pain. They all were hitting her as hard as possible and she couldn't resist the pain on all her sensitive parts as the same time. She was screaming and just after 5 minutes, she was crying so loud with loads of tears from her eyes. "Please forgive me Masters. I will never disobey you or say anything bad to you Masters" she pleaded. Her ass was already bright red and the shots were coming on her already bruised cheeks. "No excuse Melissa" said Ricky as he landed a very hard one on her cunt. She started dripping from her pussy and as the shots came in, she was moaning with the ball being hampered inside her. Robert, seeing her moaning, he decided to turn the vibrator on. He turned it to "Medium" and carried on with the cane. Her ass was showing the lines of the cane but they were all so red that it wasn't too distinguishable. Soon, Melissa came. Ricky moved the strap along her pussy and took the cum onto it. He pulled to her face and instructed her to open her mouth and pull her tongue out to lick it. She was surely bound to obey and started licking her own cum while Robert, Silvia and Andrea were still on the job. After she completely dried the belt, Ricky started spanking her to start her all over again. Robert turned the vibrator to "High" and she was wiggling her hips in an intolerable sensation. She came again but she didn't have to lick it this time. "Andrea, you lick her clean" Ricky said and Andrea stopped spanking and knelt down to start. Ricky took over the corp and pounded on her nipples. When Andrea finished, she took back the corp and got back to work. After a while, Melissa came again and this time Silvia was asked to do the licking. She knelt down and started licking while Ricky took over her corp and mercilessly hit Melissa with some power. Melissa couldn't concentrate on anything and was profusely crying and screaming and pleading them to stop. Silvia finished and took back position while Ricky came back to work on her pussy again. "50 down and 50 to go" said Robert as Melissa thought "Only 50 strokes so far?? I'm dying here and surely won't last that long to finish this" as she was moaning again despite all the pressure and pain she under. Robert turned the dildo to "Extreme High" and Melissa came for the 4th time. Ricky gave no attention to her orgasm as he continued the torment on her poor little cunt. "There is no mercy for disobedience or bad comments and I'm sure you are learning that now Melissa" said Robert with a smile. "Yes Master. I've learned the lesson and discipline so please stop Master" she said uncomfortably. It didn't stop but she was moaning again. Ricky kept doing his job so well that she came again. "How many times was that?" Ricky asked and laughed at her. Melissa looked at Ricky's face and then hung it down feeling so ashamed to tell her younger brother. "I asked you a question and expect you to answer, little lady" Ricky stammed with an unbelievably hard smack to her pussy. "5 times Master" she said. They kept on the pace and the strength as they almost finished the 100 strokes. Melissa moaned again and soon she came yet again. All her cum dropping to the ground and making the floor wet. "You can't control yourself, can you?" asked Robert and Melissa blushed and replied "No Master" with tears all over her face. They finished the 100 and Silvia and Andrea were so wet now and were dripping from their panties and down their thighs. It was not visible as they were wearing their skirts. "Get the wooden paddle and the leather paddle, Andrea" instructed Ricky. "The one with the holes" added Robert. Meantime, Melissa was coming again. "Oh, what a beauty that you are coming again and again. How times was that sweetie?" asked Ricky. "7 times Master" answered Melissa. Robert stopped the vibrator and pulled it out. Andrea came back and handed the paddles to Ricky. Ricky handed the wooden paddle to Robert. Ricky removed the weights and clamps from her nipples. "Suck her tits while we give her the spanks. Okay girls?" asked Ricky. "Yes Master" came the reply from both Silvia and Andrea and they started right away. "Her cheeks are really bruised. How can she take more spanks" Robert asked. "She should have known before being naughty. She has to take it. No mercy" said Ricky. They started the spanks and Melissa was still pleading and crying amidst of her screams. Melissa was moaning. Though there was no vibrator inside her, the sucking and ball movement made her wet. She was moaning loader and louder but the effects was not enough for her to cum. She was in deep pain and her ass and pussy were bright red than ever before. She was moaning louder and louder as the other kept sucking her tits and sore nipples. It went on for another 30 minutes and Robert and Ricky showed no mercy as they were closing down on the last few shots. Melissa was almost fainting by now but the shots came harder and harder holding her on to her senses. She couldn't lean either back or front as the shots came from both sides. She was still moaning very loud when Robert and Ricky finished the 100 shots. "Moaning for 40 minutes? Wanna cum again?" Robert asked and she nodded her head with no energy to talk. Robert came to her front and removed the ball out and penetrated himself into her. Ricky was putting all the things back into the shelf and the two girls stopped sucking and helped Ricky. Ricky didn't push yet and was kissing her. She was not in a position to enjoy the kiss but Robert enjoyed. "Did you learn your lesson yet Melissa" asked Robert looking into her eyes from a few inches away. "Yes Master. I did learn my lesson and promise never to disrespect or disobey my Masters, Master" she said facing the floor. "Good girl" Robert said and started pushing into her cunt and in a matter of seconds, she came and a few seconds later, he came inside her and fell over her. She was holding her own body against the straps and held Robert on her front for a while. Robert soon came out of her and watched her position. Her tits and nipples were so red and sore. Her pussy was all wet with her juices and cum. The pussy was also red and sore. He went behind her and observed his work on her cheeks. It was totally red and bruised. It showed the marks of the cane but not so clear as her ass was so red. He just left her tied and walked over to the sofa and sat beside Ricky while Silvia and Andrea were standing there. "Untie her and all three of you bring a wooden chair and sit next to the sofa" ordered Ricky and the girls responded "Yes Master" and went to untie the poor Melissa. They untied her and she just fell to the ground. They lifted her up and each took one arm of her walked her to get the chairs. They moved the chairs near the sofa and put Melissa in the middle one. "Tie her to the chair properly" said Robert and they did just that. They then sat on the chairs themselves. Ricky saw that the two girls were all wet beneath their skirts and had a smile. He walked over to them and straped them to the chair. He then lifted Silvia's skirt to take a better view at her wetness and then lifted Andrea's as well as she blushed at her own wetness being spotted. He removed their skirt and their shirt and left them in their bikini. He went over to the TV and put the DVD on with the film "Disciplining teenage girls". He came back to the sofa to watch the film as they all watched on. It started off with a girl seemingly in her teenage tied to a table, blindfolded and totally naked. As the film went on, it featured spanking her and asking her to do all the slut work that Robert and Ricky have done to the girls. Ricky paused the film and walked to the cupboard and took three-blindfolds. He blindfolded all the three girls with them. He noticed that Silvia was so wet that her panties are soaked and Andrea was similarly wet. He walked to the sofa and played the movie from where he paused it. "They shouldn't see this part or they will cry" said Ricky as Robert anticipated what it could be. He started liking it when her father or rather now her Master took her out with him to a disciplinary hostel and asked them to train her in their own fashion. Ricky muted the sound as well so the girls don't hear anything but the guys breathing. Robert started liking this and looked at the three girls ready for this. "We can do this ourselves and no need to get help" Ricky said as Robert felt even more excited. They finished the film and decided to do what they had done in the film though they had done most of it except for a few. They then removed turned off the TV and left the room leaving the girls as they were. They came back in the morning to find all the three girls sleeping. Ricky removed the blindfolds and waked them up. He undid the straps and let them stand up. Silvia and Andrea were wearing their bikinis while Melissa was naked. But all three were really wet and dripping their juices. He lead them to the bathroom and instructed them to take a shower and gave all the three some nice new clothes to wear afterwards. They took a shower and cleaned each other up. Silvia and Andrea helped Melissa massage her ass and tits. "We are sorry Melissa. We had to obey them to hurt you or we would have been in trouble" said Andrea and Silvia added "Yeah. Finally we had some mercy but at your cost. Sorry". Melissa just nodded and the three finished their shower and wore their clothes and waited for their Masters. They did come and saw all the three girls neatly dressed and fresh. They lead the girls to the living room. Once they had reached the living room, Robert and Ricky sat on the sofa and three girls standing in front of them. "Kneel down you three" said Robert. They complied. "Learned your lessons yet? Still some more sessions to go and once it is over, then you all will be full time slave girls to us. Understand?" asked Ricky. "Yes Master" they answered. "Good, then we start the next session then" said Robert and signaled the girls to stand up.
