They brought the girls to the swimming pool outside and let them sit on the floor near the pool while Ricky went back into the house and then to the room to open the second cupboard. It had several enama bags and gauges of various sizes, vibrators, dildos, mouth gags, blindfolds, leather straps, ropes, nipple clamps, feathers, very small iron balls, butt-plugs, tapes and a big bag He got the bag and put some of each for the two of them. He came back with the heavy bag to the swimming pool. "Blindfold and gag them?" he asked Robert. "No need, let them see what's happening, feel humiliated and react!" he said and laughed. The two girls blushed and their faces turned red feeling the humiliation already. Robert opened the bag took out the enama equipments and filled it with swimming pool water. Ricky then took one filled from Robert. They order the girls to kneel and put their head on their hands and face the floor. They obeyed. Their ankle straps were removed. Ricky inserted the gauge into his sister Andrea while Robert his gauge into his sister, Silvia. The girls have never tried this before and just know that the feeling after they are filled is extremely unbearable. They started squeezing the gauge and the water rushed into the girls body as they wiggled and screamed. "No, Stop!" shouted Andrea while Silvia knew she better not say anything and just screamed in tension and both started crying. "I said stop, jerk!" Andrea said again as she was not able to stand this sensation at all. Ricky replied by spanking her heeling ass with some force with his hands. "Disobeying will pay soon" he said as he spanked her repeatedly until the bag was empty. Robert was also done by now. "I'm so full. Please leave me Master" Silvia pleaded to Robert. Ricky reached the heavy bag and pulled out two butt-plugs and put one into Andrea's asshole to stop the water from flowing back out. He handed one to Robert who did the same. They asked the girls to stand up. The girls wasn't able to do that with their stomach so full. "Stand or be punished more severe?" Ricky shouted at them both. They slowly managed to stand up and cried "Please let go, Master.I can't. I just can't" said Andrea. "Your earlier misbehaviour leads you to a harsher treatment than Silvia" he told. "2 laps around the pool and you'll be let gone, Silvia" "Andrea, 3 laps for you" Ricky said. Robert looked at the bag and saw the small iron balls. "Wait girls. Let's insert this first" he said and inserted one ball into Silvia's cunt and took the tape and taped he pussy so it doesn't fall out. He went to Andrea and when he was about to do that, Andrea shouted "No!! Please no!". "No what?" Robert stared at her and asked. "Sorry, no master. Please! I beg you a thousand times. Please!" she started crying again. Ricky said "You'll have two balls in there and now it's 4 laps for you, naughtly little slut!". She stared at Ricky and Ricky said "How about 5 laps? 5 laps, start!" he screamed as Silvia started walking and Robert inserted the two balls and taped her cunt as well. "What's this ball for?" wondered Silvia as she slowly walked. After a while, she realized that the ball moves as she moves and it's making her pussy hot and stimulating orgasm. "Andrea's situation? Terrible" she assumed as she was crying and slowly walked around the pool. Andrea was following behind her with more tension in her pussy. Silvia walked slower and slower so she can complete the 2 laps while Andrea was walking very fast. Andrea eventually collapsed on the floor and Ricky rushed to her and had to remove the plug and expel the water. He was frustrated as he said "100 shots of the cane on your bare ass and 100 strokes with the leather on your bare pussy. You also have to re-do the enama later and complete the 4 laps" and Andrea was stunned and was crying heavier and started pleading for mercy but to no use. Silvia was on the second lap while her pussy was hot and she was dripping out of the tape. When she slowly walked and completed the second lap, she came and slowly knelt back down and buried her head in her hands facing the floor and her ass high up. "Can I have please have the plug removed now, Master. Please" she requested and Robert said "Good girl, you are learning respect" and took her to the bathroom near the pool and removed the plug so she expelled the water onto the bowl. He put his hand on the tape on her pussy and started rubbing. She started moaning and soon was about to cum but Robert stopped and said "Since you are being a good girl, I'll not tease you too much" and removed the tape and removed the balls and inserted his fingers in her cunt. It penetrated very fast as she was already soaking wet and moist. He penetrated in and out and soon let her cum. "Thank you very much, Master" she said politely. "I'll try to always obey you, Master" she adds. He leads her back to the poolside while Andrea is kneeling on the floor on her back and facing the sky. Ricky tells Robert to wait for him to come back. He goes into the house. Robert asks Silvia to kneel down and move around the pool for 20 laps. Since she wants to maintain her good behaviour, she does that. Robert asks her to shout the lap number after she completes each lap. "Yes Master" she says and starts. Robert meantime sucks on Andrea's nipples again and makes her moan. "Bad girl. Learn from your mistakes slut" he says and continues to suck. She still having the balls in her pussy, she is feeling the stimulation and drips her juices from the cunt. When her moan gets louder, as usual, he stops. He looks into the bag and finds the nipple clamps. Takes out four and attached two to each nipple. "Ouch. Stop.....ah, Stop! Stop! NO!!....Master" she shouts and tries to get up but he pushed her back to position. Silvia finishes one lap and shouts "One, Master" and starts the second. Ricky returns with the cane and the leather strap. When Andrea sees him, she shouts again "NO!! I can't take it Master. Stop it Master". Ricky sees the clamps and says "100 strokes on the pussy with the leather strap, 100 stokes on the ass with the cane.........and 100 stokes with the leather straps on your clamped nipples!" he says and smiles at Robert. "All at the same time, okay?" Ricky asks Robert with excitement. "Sure" nods Robert and Ricky disappeared into the house and came back with the wooden frame in the room. "How to take all this at once?" she thinks to herself and decides to obey hereafter without anymore misbehaviour understanding it only earns her more tough time. They lift her up and tie her to the frame in a spread-eagle position. Ricky removes the tape from her pussy and remove one ball and leaves the other one there and tapes it back. "More movement with only one there" he says and lands the first stroke on the pussy and then on each nipple. Robert lands the cane at the same time as the stroke on the pussy. He waits until Ricky comes back to strike the pussy after the nipple and lands the cane again. So that she can't back or forward when the blows come. Silvia finishes lap 5 by now and is terribly tired. Robert sees her and asks her to move on her knees to him. She does without much energy left. When she comes near, he lands the cane on her back as well sending her wild. She screams and waits. He then reaches the back and pulls out a dildo and inserts into her asshole and turns it on. She squirms and wiggles her hips. He turns it to "High" and instucts her to carry on with her remaining laps. She couldn't believe it was happening and slowing started going back to her laps. Andrea was pleading them to stop and was crying and also moaning. They started landing the strokes harsher now as they reach 25. Her nipples are in heavy pain and her ass which healed a bit is now bright red and bruised again with lines showing the effect tif the cane. She moaned louder and louder and finally came. She was still pleading to stop but they wouldn't. Silvia was moaning as well with the vibrations in her ass. She managed to finish 9 laps and came. She stopped for a while. Robert noticed that and said "Resting? 5 extra laps then. So, 25 in total" She immediately started again and thought "I should have kept moving at least. Stupid me!". This went on for another 30 minutes and within that time, Silvia had cum twice and completed her 25 laps while Andrea came 4 times and had received 95 of the 100 of each kind. Andrea was moaning again and by the time she received the 100th stroke on her cunt, she came again. Silvia waited for either Master to instruct her and finally Ricky said "Move here with the knees". She tried to catch her breath and managed to reach Ricky. Ricky asked her to bend backwards and face the sky exposing her breasts and her pussy to Ricky. Ricky landed a few sudden hard strokes on her pussy and she was screaming in agony. He then reached for the bag and took out a dildo and inserted into her pussy really deep that it almost touched the other dildo's edge inside her vagina. He turned this on to "High" as well and she was just in fantasy with the two intruders bringing her senses alive and soon, she was moaning as loud as she could and came. Meanwhile, they untied Andrea and filled the enama bag again and inserted the gauge up her ass. Ricky squeezed the bag and the water rushed in again. He put on the butt-plug again. He pulled her up with force and said "Better finish the five laps or you will be more harshly punished". She slowly walked around the pool and her pussy was stimulating pulses with the ball dancing around inside. She was moaning and when she finished the first lap, she came. She didn't stop and went on slowly as Robert and Ricky watching on. Silvia was coming again and again with the vibration in her. She pleaded to the Masters to stop the vibrators to stop with politeness but they just laughed at her. After every lap or two, Andrea reached climax and exploded. She came four times by the time she finished her five laps. They knew that a person can't stand the water inside anymore nad went to her and removed the butt-plug and she expelled the water there itself. They let her relax for a while and then asked her to go around the pool on her knees for 25 times. Robert inserted a dildo in her asshole and turned it to "High". She still had the nipple clamps on her and Ricky just added some weight to it so it hurts more. She screamed in unresistable pain and when she was moving around the pool, the weights would move causing her more pain and the vibrator stimulating her to cum. She successfully completed 15 laps when Robert turned the vibrator ro "Extreme High" and added some more weight to the already heavy and sore nipples. She already came 3 times in the 15 laps and the vibrator along with the ball us just terrible for her. She comes another three more time and finally finishes the 25 laps. Silvia had cum some 15 times and was full of tears and pleading to the Masters to show some mercy, They finally remove the dildos and tie her ankles again and let her relax on the up facing position and they strap Andrea's ankles as well and put her in the same position as Silvia next to her. They go inro the house carrying the frame. The two girls are silent and relaxing but with still the nipple clamps and the weights and the ball and the dildo vibrating inside her, she really isn't relaxing. After 15 minutes, Andrea moans louder and reaches another climax. She reaches a climax every 15 minutes and when she does, her body moves involuntarily causing the weights to tangle induce pain. Their knees were so sore but were still on their knees until their Masters return. The Masters did return with a smile on their faces. Silvia was already sleeping since she didn't sleep the previous night but Andrea was moaning and seeming came another 3 or 4 times during her Masters' absence. They removed the ball and the nipple clamps and the weight from Andrea and turned her around to remove the vibrator which was in "Extreme High" all this time. She was turned back into position and she too closed her eyes to sleep. But suddenly, the Masters used the strap and cane on their slaves' pussy to wake them up in shock. They stood there and laughed as the girls looked in terror. They landed a few more shots before they started screaming and crying. They then stopped and pulled them up and carried them to the bathroom near the swimming pool. There they turned the cold water on to wake them up totally to their senses. After some terrifying 5 minutes in the freezing water, Ricky turned the water to warm and started cleaning Silvia while Robert cleaned Andrea. They soaped their partner's whole body including their sore knees, breasts, pussy and asses. After massaging them for about 15 minutes, they inserted their fingers and started to finger-fuck their cunts. They opened the clitoris and did all the magic and very soon they were moaning again. They didn't tease them for long and inserted their erect cocks into their assholes which was quite easy to enter after all the dildos had opened it up. They pushed in and out and still finger-fucking their pussies. They came inside them and provided enough stimulation for their pussies to cum as well. They all collapse in the shower and relax still inside the girls. They order Andrea to suck Silvia's pussy and make her cum. Now, ready for any type of humiliation with fear of punishment, she starts licking Silvia's pussy. Soon, Silvia moans and Ricky started fucking her again. He came inside her again while Andrea licked Silvia to orgasm. Her head was pushed into Silvia's pussy when she stopped licking once Silvia's started coming. She hesitated and took the cum into her mouth. Silvia was ordered to do the same to Andrea while Robert started fucking Andrea. He came into her again and Andrea also came with yet another climax and Silvia knew she better lick her whole orgasm off. She did that and after 15 minutes more in the shower in the same position, Robert and Ricky came out and cleaned themselves and put on their clothes while Silvia dried Andrea and Andrea dried Silvia. They still didn't have clothes to wear. They were still naked in front of their younger brothers who are their Masters. "You two are done for now and go and rest for some 5 hours. We'll wake you up at 9.30pm for somemore activity" said Ricky. Robert smiled at the girls and asked them whether they had something to say. "Thank you for the discipline today Master and we thank you letting us rest Master" said Silvia and "Thank you Masters" said Andrea and Ricky and Robert carried them to their bedrooms knowing that they just don't have the energy to walk. They put them on the bed and get some ointment for their bruises. Ricky applies it to Andrea while Robert applies to Silvia. The girls enjoy the caressing by their brothers and thank them again as they tie them up in the bed and turn the air-conditioner on and the lights off and left the room. The ointment was cool at first but started generating heat later but the air-conditioner equalized for the heat and they both slept soon for the best rest in a few days already. They went to Melissa's room and she was moaning, squirming, screaming, dripping, sweating, crying, wiggling and moving her whole body involuntarily. But she wasn't coming which was what she wanted most since the previous night. They were starring at the sight and felt happy that they can make a girl to this situation. When she saw them, she was literally begging for mercy and to let her cum. They just laughed and Robert pulled Ricky out the room and shut the door. "Let's watch the TV showing her for a while and come back later" said Robert. Ricky didn't have a problem and they went tp watch her for some 30 minutes and then came back. "Really want to cum? Then you have to feel sorry for what you had said last night. Apologize until we forgive you" Robert said with a smile. "I'm really sorry Masters""I didn't mean to say that Masters, please forgive me, Please.""I beg you to forgive me""I'm such a naughty girl, please punish me in anyway you want Masters. Please let me cum""I'm a disobedient slut. I agree. Please forgive me and show some mercy" she pleaded for almost 1 hour before Robert finally said "You are forgiven. But since you agreed that we can punish you in anyway, we shall give you 100 strokes of the cane on your ass, 100 strokes of the wooden paddle with holes on your ass, 100 strokes of the leather strap on your pussy, 100 strokes of the leather paddle on your pussy and 100 strokes of the Riding Corp on each nipple. The nipple will be clamped and will have weights on it and your ass will have a vibrating dildo and your pussy will be taped with a small iron ball inside. Andrea and Silvia will be helping us with disciplining you. If you don't agree to this, then you can stay here for another two days without being able to cum. Your choice" She was terrified and did not want to take either of them but she had to choose. She thought about being like this for two days is crazy and that she get over with it by accepting the punishment. "Okay, I accept. Please let me cum now Masters. Please!" she said wasting no time. "Good" said Ricky. "I suppose this current thing really works. It tames anyone and makes them so eager to cum that they accept to anything" Robert said with a happy smile. "That's true, I feel the same way" replied Ricky. Finally, the long awaited climax was coming when Ricky increased the current level and Melissa came in seconds. After her climax, they removed the wire and untied her. "Your punishment just said will be later in the night while you'll receive what the other two received a while back now. They carried her to swimming pool and asked her to kneel down with her head on her hand facing the floor. She obeyed when she was finally relieved from the sensation of the current. Ricky filled the enama bag and Robert insert the gauge up her ass. He squeezed it sending the water rushing into her body. She squiemed and complained "I'm so full, I can't take this Master". This just earned her more punishment as Robert put the butt-plug and said "Complaining? You dare!" "Sorry, Master. I didn't mean to complain" Ricky reached the bag and got the mouth gag and gagged her for her own good. Robert instructed her to get up but she didn't. He then spanked her in the ass so she did finally stand up. He instructed her to go around the pool three times and reminded her that if she collapses as a result of her mistake, she will regret it. She slowly walked the three laps as Ricky and Robert watch with excitement. When she was done with the last lap, Ricky walked her to the bathroom and let her expel the water. She did so and was taken back to the pool area. They didn't put the balls or the clamps since she was going to have it later anyway. They inserted a dildo in her asshole and twisted it making he scream and squirm and wiggle her hips. They turned to "High" and Robert said "On your knees around the pool 30 times" She couldn't complain anymore thanks to the gag, but it was good she couldn't complain. She started and completed one lap and Ricky noticed that without the ball in her pussy, she would be coming so often. So he took on small iron ball and opened her clit and put it in and taped it. She was staring at him but started moving quite soon. Ricky was right and she started moaning loudly soon after. When she finished the third lap, she came. All Ricky and Robert did was sit in the chair poolside enjoy their slave perform. She completed all the 30 laps causing her to terribly would her knees. In the process, she came some 10 times. She was moaning after the 30th lap and stood up. "Did we ask you to stand up, slut?" Ricky asked. She knelt down and started crying in pain and humiliation. "5 more for disobedience" said Robert as she started off again. After one more lap, she came again. Robert came over to her and turned the vibrator to "Extreme High". As a result she came 3 more times when she finished the 35th lap. She knelt there by the pool and waited for her Masters' instructions. It came after 10 minutes ordering her to go to the bathroom. Robert went with her while Ricky packed the bag. Robert asked her to suck him off upon removing her gag. She knelt down on her sore knees without a choice and did just that. When he came, she moved her mouth out only to be pushed back by Robert "Lick clean slut" he ordered and she couldn't bear it but had to do it. She finished and Robert removed from her mouth and lifted her up and entered her into the tub. He removed his clothes as well and entered the shower with her. He turned on the warm water and cleaned her up. Massaging her whole body and soaping her thoroughly. She moaned again and came thanks to the vibrator which is still on. Robert turned it off and pulled it out. He then also pulled the ball out after removing the tape. She felt a bit relieved and started to relax. His cock was erect again and he slowly penetrated into her. He fingered her clit and explored her vagina. She was moaning again and it was getting louder. He started fucking her and came inside her soon. He simultaneously used his finger and made her cum. He collapsed with her for a while. He then washed her cunt again and came out of her and washed himself. He dried himself and put the clothes on. She came out of the tub and he dried her as well but had no clothes to wear. She walked naked to the poolside with Robert were Ricky was waiting. They went back into the house and it was almost 6.00pm. They took Melissa to the room and position her spread-eagle in the wooden frame. They then went to wake Silvia and Andrea up. They did and untied them from the bed and undid all their straps. They gave them clothes to wear so it could make Melissa's situation more humiliating.
