Note: This story was dynamically reformatted for online reading convenience. Scott was starting to get used to his new family life now his mother had married Neil. He and his younger sister Chloe had moved in with Neil and his daughter Vicky about a year ago and things seemed to finally be settling down. Chloe and Vicky were about the same age, and into the same sort of thing that teenage girls around the world were into, clothes, music and pushing the boundaries when it came to what they could get away with. Scott had caught Vicky looking at him when she thought he wasn't aware a few times, and he had a sneaking suspicion that she fancied him. He didn't really want the attention however, as she was kind of his sister and besides she wasn't really his type. Don't get me wrong, she was still a girl blossoming into womanhood so there was always some spark between them, however she was a bit plump for his tastes. Once he had bumped into her as she was coming out of the bathroom with her towel just a little too low to be considered decent, and the sight of her plump body still flushed from the hot shower definitely sent his blood pressure soaring, however all in all he decided to leave well alone. One incident involving her had also triggered a few fantasies (well more than a few) however this was now a couple of months in the past. He had been lying in bed watching TV when he had heard Vicky and her Dad having an argument in the next room. This was not unusual, however as the argument had seemed to reach a crescendo things definitely got more interesting as Neil announced, "Right, that's IT! I am sick of you acting like a child so I am going to treat you like a child. Pull you jeans down NOW!" "Christ! she's going to get spanked!" thought Scott "Dad NO!, you can't I'm too old .. please!" pleaded Vicky to no avail "Do it NOW or I swear I'll make it even worse." Scott could hear nothing but sobbing for the next few seconds, and then the words that made immediately made him as hard as rock. "And your knickers" "Oh my GOD!" thought Scott, shocked beyond words that Vicky was going to have to pull her knickers down in front of her dad and get spanked BARE! "Dad, NO! you can't be serious!" "Do it now, or we do it in the lounge in front of everyone, your choice." The next second were just filled with sobbing and he could see in his minds eye the image of Vicky pulling her knickers down exposing her plump pussy and ass. "Now bend over my knee" For the next 4 minutes Scott could hear the sound of Neil's hand smacking Vicky's bottom really hard, and although it felt wrong he lay down on his bed and masturbated whilst listening and imagining the site that he would see if he were a fly on the wall. Vicky's plump buttocks turning red as the spanking continued, her lightly covered vulva slipping in and out of sight as she wriggled with the pain of the spanking. He came quickly after the spanking had finished and just lay there thinking about what had happened. About 20 minutes after the spanking, Scott left his room completely by coincidence at the same time as Vicky. As they saw each other their eyes locked and Vicky blushed a profuse shade of red at the obvious realization of what Scott must have heard. She said nothing, and they never spoke of the incident until much later and after the next time Vicky was spanked. The next spanking was to be in a completely different league when it came to embarrassment and humiliation. A couple of months after Scott had heard Vicky being spanked, his sister Chloe and Vicky's relationship seemed to go through a bit of a rocky patch and they argued like cat and dog. Scott's Mother Michelle seemed to be stuck in the middle and was quite frankly at the end of her tether refereeing the 2 arguing girls. One night who's significance only became apparent later, Scott heard his mother and Neil talking about what to do. His mother was practically in tears as she told Neil that she felt that nobody respected her and the girls in particular treated her like a doormat. Neil tried to comfort her and he then heard the 2 of them discuss ways of imposing some sort of discipline in the house. Bored, Scott went back to listening to his music and forgot about the whole thing until a couple of days later when Vicky and Chloe had the most monumental argument about one using the others lipstick. It was late in the evening and all of the kids in the house were fresh out of the shower in their night clothes, Scott and Vicky in a pair of pajamas, and Chloe had pajama bottoms, a vest top and a dressing gown on. Chloe often dressed like this and Scott found it a bit disturbing when the dressing gown would occasionally flap open to reveal the fact that she wasn't wearing a bra underneath. He tried to avert his eyes from the occasional flash of the outline of breast and nipple, but like all teenage boys he was programmed to look at anything remotely sexual so often found himself glancing across. Scott was upstairs watching the TV and could hear Neil and his mother shouting at the 2 girls downstairs and could tell that things were even more heated than normal. He was surprised when his mother told him to come downstairs and all 3 kids were marched into the living room. They were then made to all sit next to each other on the couch as Neil started his lecture. "I don't see why I need to be down here, I haven't done anything wrong!" said Scott. "you'll see soon enough" was the slight cryptic reply he then got from his mother. Neil began lecturing in earnest "Right, we are absolutely SICK of the constant arguing and bickering in this house, and things MUST change" "Your Mother was almost in tears the other night because NO ONE in this house listens to a word she says!" Vicky, still hot and bothered from the argument then foolishly muttered "She's not my mother" This was a mistake, Neil grabbed her under the shoulder and shouted "GET UP!" before planting 5 hard smacks to her pajama covered bottom. "You!" SPANK! "will listen" SPANK! "to what I have to say!" SPANK! SPANK! SPANK! All 3 children were shocked. Vicky was mortified with the embarrassment of having her bottom smacked in front of the rest of the family, Chloe who had not been privy to the sounds of the spanking weeks before was shocked that a teenage girl could be treated like this, and Scott was really really aroused! With tears rolling down her cheeks, Vicky silently took back her place between the 2 other children to listen to the rest of the lecture. She was terrified of what might happen next and decided to try and keep as low a profile as possible. "Right! as I was saying, no one respects Michelle and that HAS TO CHANGE" "We have talked about this, and decided that from now on, when ANY OF YOU no matter how old acts like a child, you will be treated like one" Scott and Vicky had heard this phrase before, and Scott's cock twitched in anticipation of the show to come. Vicky was on the edge of panicking as the thought entered her head "Surely he can't spank my bare bottom in front of everyone!" The thought of it horrified her!, however at the same time as being horrified an unexpected and unwanted tingle of sexual excitement ran through her sex. Neil continued "From now on, Michelle will be the person dishing out discipline in this house" "I was hoping that this was not going to be necessary, but unfortunately I was wrong!" At this point Michelle brought across a chair and placed it about 2 meters from the couch. The atmosphere was charged with the shocking reality of what was about to happen. Michelle sat down in the chair, and Neil then said "Vicky stand up". Vicky knew what was going to happen, and with trembling legs she stood up and started to plead "Please Dad, not in front of everyone, you CAN'T .. PLEASE!" "That's enough, now pull you pajama bottoms down NOW!" Clinging to the fact that her Dad had not mentioned her knickers, she complied and then stood there with her hands clasped together in front of her crotch to keep the show to a minimum. Then, she heard the words she was dreading "And your knickers" Scott was beside himself, "OH MY GOD!" he thought, Vicky was going to have to pull her knickers down IN FRONT OF EVERYONE! He thought he was going to explode. Chloe was equally shocked, this simply couldn't be happening! The humiliation of what was being asked of Vicky was too big to comprehend. She looked over at her brother who looked wide eyed and shocked at the spectacle he was about to see. Wide eyed and horny she thought with the sudden realization of what must be going through his mind. Chloe was very very scared of what was going to happen to her, and she decided that no matter what there was just no way she was going to pull her knickers down in front of Scott and Neil. She just couldn't! Vicky, having been punished like this before (though never in public) was more resigned to her fate, and slowly lowered her knickers half way down her thighs with one hand, while strategically holding the other over her pussy. She then held her hands clasped together in front of her crotch and waited for the call to go over Michelle's knee. "Hands on your head and face the rest of the family" said Neil. "NO! PLEASE! NO! you can't! .. everyone will see me naked NO!" "DO IT NOW! Or I swear it will be worse" Vicky really had trouble thinking how worse it could get, but she was terrified, and so trembling and crying did what was asked. Scott and Chloe were speechless, and just stared at their new sister, pussy on display in front of them. Vicky was one of those girls with very very blond gingery hair that meant she hardly had any eye brows or body hair, and it was immediately apparent that her pussy was the same. She hardly had any pubic hair at all which must have added to the embarrassment as it left her pussy even more exposed and made her look even more childish as she waited for her spanking. Scott was beside himself, as he stared at her young slit he thought he was going to come on the spot! He had never seen a real-life pussy before, and here he was ogling his new sisters completely naked pussy! "Now bend over Michelle's knee" Trembling she complied and Michelle immediately started spanking her step daughters naked buttocks very very hard: SPANK! SPANK! SPANK! SPANK! Spank after spank rained down on Vicky's plump buttocks which quickly turned pink from the abuse. As the pain increased Vicky seemed to lose control and her original intention of keeping her legs closed to avoid flashing her pussy was quickly forgotten as her legs wildly flapped. Scott and Chloe could clearly see her almost hairless labia and knew that they would replay this moment again and again when alone in their rooms. And then it was over. Vicky got up, pulled up her knickers and pajamas and went to sit back in her spot on the couch. Scott had strategically placed a cushion on his lap to try to hide his erection, but as Vicky sat down she knocked it off. Wearing only pajama bottoms it was very very clear that Scott was extremely excited, and Vicky took a sharp intake of breath when she saw the affect her spanking had had on him. Their eyes locked for a moment before he quickly retrieved the cushion and put it back in place. Chloe had also seen this, and it just added to the weirdness of the situation. Then the realization that it was her turn next flooded back. Surely they just COULDN'T expect to spank her in front of them like Vicky! The thought that her brother would get equally turned on by seeing her pussy also flitted through her mind. She felt that she had gone to hell! This must be a nightmare. Before she had time to ponder much more, Neil told her to stand up and go across to Michelle "PLEASE MUM, DON'T DO THIS!" she implored her mother, but it was all to no avail. 'Take off your dressing gown'. Chloe had desperately wanted to keep this on to try to keep some dignity and really regretted not wearing a bra under her vest top. She took off her dressing gown and stood there in her vest and pajama bottoms feeling very very exposed. For some reason her nipples had gone really hard and she was aware that Neils eyes kept on flitting to her chest "Please just get this over with!" she asked her mother. 'Pull your pajama bottoms down'. This was the part she had been dreading. Somehow she clung to the hope that she would not be asked to pull her knickers down as there was just no way she could do that, it was just too horrifying for words. As she stood there in her skimpy vest top which didn't even go down as far as the top of her knickers, her mother spoke the dreaded words "Now pull you knickers down" "NO! I CAN'T! PLEASE DON'T DO THIS!" "I can't let Scott and Neil see me naked, it's not right!" Her mother was really really angry, Vicky had been spanked like that so there was no way her own daughter was going to get away with it. "Embarrassment is a big part of the punishment, now get them down RIGHT NOW or it will be much worse!" Michelle and Neil had spoken about what to do if one or both of the girls refused, and had a plan. They had both hoped that it would not have been necessary, but Chloe's insistence no keeping her knickers on was starting to look like they would have to employ even stricter measures. "LAST CHANCE! PULL THEM DOWN NOW!" Chloe just froze, she felt like she physically could not do it. She could feel Scott and Vicky's eyes on her body imaging what lay beneath her clothes. She just couldn't "NO! I CAN'T PLEASE!" Her Mothers voice changed to a slightly softer tone, and she then asked Chloe to put her hands on her head. Relief flooded through Chloe. When Vicky had been made to do this her knickers were down, so they must have come to their senses after all. She was wrong. Quick as a flash her mother grabbed the bottom of her vest top and whipped it up over Chloe's head. Chloe didn't have any time to react and before she knew what had happened she was bare breasted in front of everyone. "OH MY GOD!" though all of the children at the same time. Scott's jaw hit the floor as he saw for the 1st time his sister's naked breasts. His sister was definitely a looker, and although Scott was her brother he couldn't help but admire her body. She was petite, about 5"2, slim, and with the kind of skin and glowing complexion that older women would die for. She had just about the right amount of body fat to make her look healthy without being overweight. Her breasts were actually very small, a conical shape with puffy light pink nipples and aureole that covered a large part of their small size. Her belly was soft looking rather than toned and with her perfect skin and complexion was incredibly sexy. Scott took this all in in a flash before the shocked Chloe instinctively covered both breasts with her arms. Quick as a flash her mother yanked Chloe's knickers down to her ankles and tried to completely removed them. "NO! NO! PLEASE!" Chloe literally screamed and crouched down into a ball holding on to her knickers. "NO! NO!" Michelle was having none of it and tugged hard at Chloe's Knickers which were now at her ankles. Chloe lost the fight to keep her knickers, and in doing so fell back slightly on her bum. Reaching behind her to break her fall her legs instinctively opened to give her some balance. The effect was like dynamite on Scott. His sister was basically lying on the floor, naked, with her legs wide open! It was a classic porno pose and he drank up the site of he pink labia nestled between soft looking pubic hair. Chloe's humiliation could not have been more complete as Michelle furiously tugged her nude daughter to her feet and told her to put her hands on her head. Again she refused, almost hysterical by now 'Right! do it NOW! or you get the cane!' Chloe was beaten, she couldn't believe what was happening and wanted it to just end, and so she finally complied and stood completely exposed, completely naked and completely on display to her whole family. Scott drank up the sight of his slim young sister's nude body, pale thighs and perfect pubic triangle. Pale pink nipples on small perfect breasts. His cock felt like it would explode! After remonstrating with her sobbing and naked daughter for a couple of minutes she finally pulled her over her lap and began spanking her SPANK! SPANK! "You WILL" SPANK! "Respect me!" SPANK! SPANK! SPANK! SPANK! Just as Vicky's had done, Chloe's legs parted with each spank offering everyone even more flashes of her most intimate regions. For what seemed like an age the spanking continued and Chloe's backside went a deep shade of pink. Scott couldn't help look down at her small breasts which bounced with every smack. He felt he would never be more aroused in his life! And then it was over, Chloe jumped off her mother's lap and ran still naked up the stairs to the safety of her room. Scott and Vicky quickly went off to their respective rooms. As soon as his bedroom door was closed, Scott quickly dropped his pants and masturbated himself to a climax very very quickly. Vicky was confused as to why she had been SO turned on, but out of the need for comfort or the sexual element of the humiliation she had been through also lay down on the bed and quickly brought herself to the most explosive climax of her young life. Scott and Vicky were not yet aware that the incident had sown the seeds for what was to become the most erotic encounter of their young lives. to be continued ...
