Robert guided Silvia into the house and helped her remove her shoes and socks. Then he brought her upstairs where he asked Ricky which room and he pointed a room. Silvia realizing there is another guy here, she is feeling quite excited but uncomfortable and ashamed as well since it was her younger brother controlling her. Robert and Silvia entered the room and as Silvia was blindfolded, she didn't see anything. Robert was excited and amazed of what he saw. There are two wooden framed racks to hold the person in spread eagle position, an examination table, a bed, two huge cupboards, three comfortable easy-chairs, four hard wooden chairs, a four-seater sofa set, a TV with DVD player and a few electrical sockets. He put Silvia in one of the hard chairs and tied her with a rope which was hanging near by to the chair. He couldn't wait to see what was in the cupboards but he thought he'll wait for Ricky. He sat on the sofa for a while and then he went to see the DVDs they had. He saw a nice BDSM film called "Training a girl to be a slave" and another one called "Disciplining teenage girls". He was excited about all this and suddenly his erection was so much harder than it was. Ricky cane in with both his sisters in the sane state as Silvia, blindfolded and gagged. "Let's remove their blindfolds" said Robert and Ricky removed Melissa's blindfold first and then Andrea's. They were both stunned to see that they have guests in their house and see that Silvia was bound to a chair in their own house. Silvia still had the blindfold on and Robert told Ricky that they would leave it on her for a while. Melissa was about 5"8 and quite the sane size breast as Silvia. She was slim and attractive. Well she was only 19 years old. Andrea quite resembled her sister in her body shape and face buy she was a bit taller though, 5"10', Ricky started off with Andrea first and asked Robert to undress her. He was just so excited and removed he shirt and her skirt to reveal a stunning pink bikini. He then left her and went to Melissa and unbuttoned her blouse and her jeans to reveal yet another identical bikini. "It's their uniform" Ricky said smiling. Silvia now realized that there are more than one guy and she tried to move and release herself from the chair. Robert noticed this and said "It's time for you to get Silvia" he laughed. Robert went over to Silvia and removed the rope and got her up and pushed her to Ricky. Ricky removed her T-Shirt and caressed her breast a bit and then removed her mini-skirt. She was still blindfolded and was already feeling so humiliated. Ricky removed her blindfold so that she can see him, Melissa and Andrea. All three girls are bound by their wrists and ankles and are standing in front of this two guys in their bikinis totally helpless. Ricky asks Robert to start with Melissa first so that he and the other two girls can watch. Robert takes Melissa and caresses her breasts for a while and then puts her on the examination table and removes her ankle straps and asks her to spread her legs. She obeys knowing what would happen if she doesn't. Robert fastens her ankles to the corners of the tables and then releases her wrist straps and fastens them on the other to corners. Melissa is facing down on the table in a spread-eagle position. He removes he mouth gag and asks whether he can spank her on the bare ass. "She's all yours and do whatever you want" comes the reply from Ricky. Robert happily removes her bra and then her panties. He sees that there is a huge dildo buried in her asshole. He curious unfastens the straps and turn her around and finds that she also has a dildo in her pussy! He decides to turn on the dildo in the pussy and put it in low. He fastens back the straps and she is again facing down. Andrea and Silvia look at this feel their juices dripping as well. Robert tells Ricky "Watch Silvia squirm now cum a while later and passes his remote to Ricky. Ricky feels Silvia's pussy and notice that there is a dildo there. Robert informs that there is one more at the back and Ricky turns her around to find that one as well. He points at her pussy and presses the "Low" stimulation and watch Silvia wiggling and squirming. He brings Silvia to the wooden frame and ties her fixes her position spread-eagle as she shouts. "You're naughty Silvia. Be obedient like them and you'll suffer less" he tells Silvia and she looks in shock. He decided to punish her for that and turns the vibrator to medium. Silvia shakes her hips round and round while Ricky gets a pair of scissors to cut off her panties first and then her bra. "Nipple clamps" exclaims Riaky as he sees Silvia's bra drop down. "Yes, quite painful but useful" says Robert. Ricky pulls her clamps and removes her gag so he can hear her shouts and moans better. By this time, Melissa is already moaning loudly and notice that the table is getting wet and removes Melissa's gag as well. She moans louder and explodes her orgasm on the table. Robert turns the vibrator medium and asks Ricky about the paddles and stuff. Ricky opens the first cupboard to reveal leather paddles, ping-pong paddles, wooden paddles, wooden paddles with holes, leather straps, riding corps and canes. "Which does she takes the most from you guys?" asked Robert and "The leather straps" replied Ricky. Robert thought then there was no point in using the Leather Strap and took two riding corps and held one in each hand. Silvia had cum by now and was moaning again while Melissa had cum the second time and was also moaning again. Robert said Andrea must be bored so how about you spank her first said Robert and Ricky did just that. He took Andrea to the frame next to Silvia and positioned her in the same position as Silvia and Andrea didn't refuse anything as well. She knows what would disobedience cause. Robert started spanking Melissa with the riding corp on both cheeks at the same time. She was moaning more louder and came for the third time while Silvia also came for the third time right then. Robert turned Melissa's vibrator off so she could concentrate on her ass being spanked. Ricky had taken the Leather paddle to warm up both Silvia and Andrea at the same time. He waited for Silvia to cum the forth time by increasing the stimulation to "High" using the remote, and she came seconds later. He then stopped the vibrator and started spanking them both harder and harder. He then removed Andrea's gag as well. SMACK, SMACK, SMACK, SMACK, SMACK, SMACK, SMACK, SMACK, SMACK, SMACK, SMACK, SMACK came the noise when the paddle hit their young cheeks. Silvia couldn't believe the strength in Ricky's spankings and started screaming while Andrea kept it to herself and started crying as a result. "No screaming Silvia" Robert said while he was spanking Melissa harder and harder. He stopped for a while as Melissa took a moment for her breath. He asked Melissa to raise her ass up as high as she could after every spank and she should count the number on each ass like "Left cheek 1" "Right cheek 1". "It won't be even on both sides so keep your count correctly or you have to start all over again" "Hundred on each" he said as Melissa screamed "What!!!!" so loud. Ricky heard that and frustratedly came to the table stopping his work on those two girls' asses. "I'll handle that Ricky" "Get back to work" Robert said before Ricky did something. "Since you disobeyed me, it will be 150!!" he said with a big laugh. "My cheeks are already so hot and how can I take 150?" she thought to herself and tears running down her face. "No mercy today girls" Ricky announced as his hitting was harder and harder each time. He paused and said "Warming up is over" "Start counting your hits and be sure to step behind the line in the frame after every spank, understand?" he asked with authority. "Yes Master" said Andrea while Silvia said "Yes" "Where is the respect Silvia?" he asked and Silvia replied "Sorry Master, Yes Master" "That's better. 75 for you Silvia and 100 for you Andrea" he said. He hit the paddle so hard against their cheeks, that after each SMACK, they say "One, Two, Three etc." and an "Ouch, Ah" and move back behind the line and the next one comes right then. Silvia was tired at 25 and stopped counting while Andrea made sure she was counting. Well that was until some 40 and she doesn't have the energy to count anymore as well. He kept spanking them while they counted within themselves. Robert giving Melissa the 150, was doing quite well. Melissa counted to 45 and stopped counting as well. The corp came SWASH SWASH each time and she responded "AHH NO, OUCH!". Well it is totally only 75 for Silvia and 100 for Andrea while it is 150 on the right and 150 on the left for Melissa. When Silvia counted 75, she shouted "75 Master". Ricky without stopping yelled "What 75? Is it 75 after 25?" he asked with a huge laugh. She knows she can't take anymore. "Please Master, it's enough. I can't bear anymore. Please, Please!" she pleads while responding "OUCH" to the spanks. He says "Okay, you are free to go" while signaling to Robert not to talk. "I also can't take this anymore. Please let me also go, Master" says Andrea in a low tone as she's already crying like the other twp girls. "I just wanted your response Andrea. And Silvia, you've completed only 25 and Andrea, you only 41" he says "Since you both are talking out of permission, Silvia, yours increases to 100 and Andrea, yours to 150" he says in a confident tone. "Since you both are not really co-operating, we'll start all over again from 1 and not with this simple leather paddle anymore, let's try the wood!" he says and walks to the cupboard to grab a wooden paddle and smiles at Robert. Melissa realizing this starts counting again from 45 because she knows saying anything higher that would earn her more and not less. "Left cheek, 46" "Right cheek, 46" and as it comes down SWASH, she goes AHH and OUCH and counts. Her cheeks are now so bright red and Robert spots bruises and tells Ricky but Ricky says "Same here, just go on". The girls are bound helplessly and are being spanked by their younger brothers or rather they're Masters now with total authority. The girls are so wet and these guys can just smell that. The girls can't stand it anymore but without a choice, keep counting. The wooden paddle with the holes removes the air between the paddle and ass so the smack is much harder and the wood itself is so hard and Silvia and Andrea can't are screaming and crying like crazy. Ricky decides to put the mouth gag on for the rest of the spanking on both of them and says "I'll count for you since you girls scream too much" He counts "78, 79, 80" and so on. They don't move back begubd the line anymore so he decides to tie a thin rope in the middle of the frame so that when he spanks, they push forward against the thin rope and the causes extreme pain to their pussies. Silvia still with the dildos in place feels less pain than Andrea who has no dildos inserted. Ricky notices this and first turns the vibrator to "Extreme High" with the remote on Silvia. Meanwhile, he spanks Andrea. She hits the rope and feels the pain. After a few times , she knows she must step behind the line. Melissa miraculously is still counting and puts her ass up for Robert's spanking. SWASH "Left cheek 134" "Left cheek 135" "Left cheek 136" "Right cheek 133". She manages to count though the spanks are uneven. Silvia is now moaning so loud inside her gag and she explodes her orgasm but Ricky doesn't stop the vibrator and continues the spanking on Andrea "103, 104, 105" he counts for her. He stops and turns Silvia's head and stares in her eyes. Silvia feels the fear and the vibrator is just getting her senses. She stares at Ricky and moans so loud. Silvia cums again in another massive orgasm. Ricky stops the vibrator and removes it so she can feel the rope. She felt the rope a few times as he was counting dorn from 20. "17, 16, 15, 14". Melissa was almost done as well. She was still counting without a choice. "Left cheek 146, Right cheek 148". When she reached "Left cheek 149, Right cheek 149", she put her ass up and waited for the last ones on both cheeks. Robert was waiting for her to anticipate the last one eagerly. Ricky reached "4, 3, 2" and stopped while he also waited for them to anticipate the last one. He land a very very hard SMACK on Silvia after removing her gag. She screamed so loud on that one as is it was a 100kg iron crashing her off. He removed the gag on Andrea as well and said "Beg me for the last one Andrea". She just did that with all the energy she had left in her. SMACK came the last one on her. She screamed a lot louder that Silvia. Melissa was still hanging her ass up in the air waiting for the last one. She couldn't hold it there anymore and let it down. "Up Melissa, right now" said Robert. He land the last one on each cheek at the same time with all the force he had. She went crashing down on the table. By now, all the girls had several bruises in their ass cheeks and they were as red as it could get. They were crying profusely and Silvia and Andrea couldn't stand anymore. Silvia was worse since she had cum several times during her spanking. But all three girls were dripping their juices and Andrea hadn't cum yet and waiting to cum very seriously. Ricky and Robert were tired and their cocks were so erect and hard. Ricky went to get some Vaseline and applied onto Silvia's asshole, after pulling her vibrator out and burying it in Andrea's pussy. Then he applied the Vaseline on his own cock. He then passed it on to Robert who applied it to his cock and Melissa's asshole after pulling out the vibrator.He walked over to Andrea and put the vibrator in her ass and turned it on. He turned on Melissa's vibrator to "Medium" while Ricky turned on Silvia's to "High". Andrea was watching as both Ricky and Robert entered into their partnews assholes. They just penetrated but didn't release themselves out and fuck them yet. They stayed inside them and felt the vibrator's sensation at the tip of their penises. The girls were already moaning and were about to cum and the guys started pushing in and out. Silvia started to cum first and was still moaning. Ricky came next into Silvia's body. "I am just raped by a younger guy who I don't even know" Silvia thought as she was almost unconscious. Melissa and Robert came together. Melissa couldn't stand two simulations at the same time and collapsed on the table itself. Robert came into her and collapsed right on top of her. Andrea looking at this started dripping profusely from her pussy. Ricky noticed this and turned the vibrator in Andrea's pussy to "Extreme High". She was moaning so loud but before she could cum, he turned it off and let her stand there embarrassed and wanting to cum so badly. The vibrator in her ass is on but it couldn't stimulate her enough to cum though she was moaning loud. Robert came out of Melissa and told Ricky to spank Andrea in the pussy to cum. "You take the hounours" Ricky said and untied Silvia and tied her to the chair facing Andrea's front body. He untied Melissa and tird he on another wooden chair next to Silvia facing Andrea as well. Silvia and Melissa couldn't sit there as the hard wooden chair caused their butt to hurt more. They struggled but to no avail. They watched Robert use the Riding Corp and spank Andrea in the pussy. Her vibrator at the back was still on. She kept screaming louder and louder and couldn't bear the pain of the Corp in her bare pussy. He stopped after 15 strokes and felt she shouldn't take this anymore like this. So, he took the Vaseline and put it on his fingers and her pussy. He slowly pertrated with two fingers and opened up the inner layer. She was exposed and at the edge of coming after this sensation but didn't cum yet. He took back the Riding Corp and started spanking her harder and harder with it. She just couldn't take it anymore and was crying heavily once again. He didn't stop until she came. After about 10 on the exposed pussy, she came with an overwhelmingly explosive orgasm. He turned the vibrator in her ass off and pulled it out. He was again so erected and entered into her ass without any Vaseline. It was rough and tough as he entered her. "Ouch" she cried as was penetrating into her asshole. It hurted her more when he was literally fucking her. He came into her and collapsed behind her. She pushed against the rope in severe pain carrying his weight on her back. Her pussy was hurting as a result. After almost 3 minutes, he finally got up and released himself from her and untied her. He put her on another wooden chair next to Melissa and Silvia who are dying of pain sitting the wooden chair. She was no exception and felt the pain running around her whole body. The heat is too much for these girls to handle. They remain silent as Ricky and Robert are laughing and cracking jokes at the three of them. They feel so humiliated but are bound to obey their Masters. They leave the three girls in those chairs and leave the room. This allowed the three girls to talk. "Well our parents are not coming in the next 2 months" said Andrea. "Same here" said Silvia. "It's terrible to be so humiliated by our younger brothers like this" said Melissa. "The pain is too much more than the humiliation. These clamps are killing me and I can't bear it anymore. My ass also hurts" said Silvia. "No choice. If we had been liked by our parents, we wouldn't be here like this" said Andrea. They were too tired to talk any further and were so tired and decided to take a nap in the sitting position. After almost 3 hours, Ricky and Robert returned and released the clamps off Silvia and the vibrators off Melissa. They took the three to the bathroom where they turned on the hot shower and filled the tub. "45 minutes" said Robert and they both left. They were so eagar to massage their so red butt and Andrea massaged the pussy she got spanked by as well while Silvia massage her sore nipples as a result of the clamps. They soaped each other and relaxed a bit. "I feel like we are slaves and forced to be so shameless and humiliated" said Silvia and the other two agreed. "We don't have a choice as we are asked to be trained by our parents" said Melissa. "Never been so ashamed and humiliated like this ever before. As a fact, never been naked in front of a boy before" said Andrea. "We were fucked for the first time in our lives" said Silvia and "this is to each other's younger brothers" added Melissa. Their time was over but they were enjoying the water so much that they forgot the time. Ricky and Robert returned. "Did you know we said 45 minutes" said Ricky. "Sorry Masters" replied all the three. Whatever they think between the girls, they still have to obey their Masters. The three left the tub and dried themselves up.
