How Could My Little Sister Be So Perverted? - Episode 18

"Hey, you big pervert."
My sister suddenly called me at breakfast time today.
"Huh? What?"
"School's starting soon, so come with me to buy some new clothes... and other things..."
"Huh? New clothes? You wear a uniform to school, and why didn't you go by yourself?" I was surprised.
"I can't wear the uniform every day, what will I do on weekends? And... I... I need someone to go with me... Brother, come with me!" Ran Ping blushed again.
"Okay, I got it. I'll go after dinner. Oh, wait, are you rested enough?"
"I'm mostly fine now, so waiting... is okay..."
"Alright, let's eat quickly, and then we'll get ready to leave."
My sister and I finished our meal quickly. Ranping went back to her room, changed her clothes, and came back. She finally changed out of the loose t-shirt she wore at home every day and put on a tighter long-sleeved shirt, a long skirt that reached her ankles, white stockings, and a small pink bag.
"Hey! Why are you staring at me for so long? You pervert, you're disgusting."
When I came to my senses, I realized that I had almost never seen a well-dressed girl up close before.
"Ah... my little sister is so cute, I couldn't resist, hehe."
"Hmph, you big pervert!"
"My sister looks really good in white stockings. I want to see what it looks like when those white stockings are tied up on a tiger bench."
"Hey! You pervert!"
Ran Ping quickly walked past me, went to the entrance, put on her shoes, and I followed her.
"Hey, aren't you hot dressed like that? It's the height of summer."
"Hmm...it's not hot...I'm fine..."
"Alright then, let's go, I'll take you to the nearest shopping mall."
It's still quite early, and there aren't many people on the street, but it's already very hot. I glanced at my sister walking beside me, and she looked like she was sweltering.
"Um...it's still really hot, isn't it? So why are you wearing such thick clothes?"
"This...this...I don't really want others to see me..." Ran Ping said hesitantly.
"Huh? No way, what's wrong with my sister..."
"Ugh, okay, stop talking."
"this..."
When we arrived at the mall entrance, there were many more people than on the street. When my sister saw so many people, she immediately hid behind me and grabbed my clothes tightly.
"Eh, wh...this is..."
"I...I'm scared...there are so many people..."
"Huh?" I finally understood why my sister didn't go out to buy clothes by herself. It turned out she was shy. But that's a bit too much.
"Don't go!" Ran Ping hugged my waist tightly.
"Hey! But... it's hard for me to walk like this."
My sister seemed to be having a fierce internal struggle. Finally, she slowly let go of my arms, but she still held tightly to the hem of my clothes.
"Don't...don't walk too fast."
"Um...can I hold your hand?"
"No! That's something only couples do!" The younger sister suddenly blushed again. "We're just siblings, right? Right?"
"Uh, okay, okay, I know. That's all for now. I won't walk too fast."
When we arrived at the clothing store, there were fewer people, and my sister finally let go of my hand.
"Okay, hurry up and pick out your favorite clothes." I stood beside my sister, watching her.
Ran Ping picked out several long-sleeved clothes and long skirts as soon as she arrived, and then hurriedly wanted to leave.
"Wait, these clothes are too hot. It would be better to choose short-sleeved ones." I said, taking the clothes my sister had chosen.
"I... I said I don't want to..." The younger sister's voice was so soft it was almost inaudible.
"Stop, stop, stop! Ranping is so cute, why don't you want to show her to others? You're just too insecure. Believe in yourself! Ranping is the cutest girl I've ever seen!"
"Eh, I...I...Does my brother really think so? Cute and stuff..."
"Of course! Wearing those pretty clothes will make you even cuter!"
Ran Ping shook her head vigorously, as if making a decision, and finally looked at me, saying, "Then...then I'll trust my brother this once..."
In the end, Ran Ping chose a short-sleeved shirt and a short skirt. She changed into the new clothes and put the old ones away. A pair of fair and slender thighs were revealed from under her skirt. Although I had seen Ran Ping naked many times before, her thighs looked alluringly cute when she was dressed.
"Alright, let's go, we can leave now."
"Wait, I...I feel like a lot of people are watching me." Ran Ping pinched the hem of my clothes again and said shyly, "It feels...so weird."
"What are you afraid of, Ranping? Believe in yourself. You are the most adorable. Don't be afraid of other people's opinions. They see you because you are outstanding. Come on, don't be afraid, come with me."
I strode forward, and Ran Ping hesitated for a moment before following closely behind.
I checked my watch and realized it was almost midnight.
"It's almost noon now, let's go grab some lunch."
"Hmm...aren't you going home to eat?"
"We finally got out of town, let's eat out. Here, I know a really good snack shop nearby."
This shop is near the school. I used to eat here with Zhuang Yu often. Today, I brought Ranping here to familiarize herself with the route to school.
I spent the morning shopping for clothes with my younger sister and we had a meal together. It was quite a happy time. My sister's shyness has improved a bit; she's not as timid and hesitant at mealtimes as she was at the beginning. But I'm still very curious how my sister, who was so shy, grew up to be this big.
Finally home, my sister and I collapsed onto the sofa, exhausted. It felt like my sister was a completely different person the moment she got home; she became lively again.
After lying down for a while, I asked, "Hey, Ranping, I just thought of a new way to play, do you want to try it?"
"Huh? What kind of game is it?" Ran Ping immediately became interested.
"I can't tell you, but my little sister will definitely like it."
"Hey! You big pervert, all you do is keep me in suspense! I want to play!"
"So...when are we done playing?"
"Tonight, just tonight, okay!"
"Huh? Tonight?"
"Yeah, school's starting soon, and we definitely can't play too much after school starts, so we need to make the most of our time to have fun before school starts!"
"Alright, alright, that's it for tonight. Little sister, go and get some rest. You must have used up a lot of energy this morning." With your sister staying home like this every day, her stamina must not be very good.
"Hey, you big pervert, come over here for a second, to my room." Ran Ping stood up and went upstairs.
"Huh? What?" I quickly followed.
When I arrived at my sister's room, she opened the wardrobe and took out a neatly folded piece of clothing.
"Ah, is this the maid outfit I first saw my sister wearing when she was self-bound? Heh, I still remember that scene."
"Stop, stop, stop! I'm so embarrassed!" Ran Ping buried her face in the closet, her voice muffled, but I could imagine how red she looked.
"this..."
My sister then took out a set of clothes that looked like a cosplay outfit and threw it on the bed.
"This looks familiar...wait, what is this?" I unfolded it and realized, "Is this a cosplay of Madoka Magica from 'Puella Magi Madoka Magica'?"
"Mmm." Ran Ping nodded shyly.
"Pfft, so my little sister likes cosplay too, hehe."
"No! Don't laugh! Humph!"
"I think my sister's hair is perfect for cosplaying characters who naturally have white hair."
"Huh? Like who?"
「这个嘛，让我想想...emmmmm，《魔女o旅》里面的伊蕾娜，我觉得很合适，尤其是性格上跟妹妹一样，很屑！嘿嘿嘿。」
「诶诶？！大变态！坏蛋！说谁屑啊！」
「等等，还有《埃罗芒o老师》里面的纱雾嘛，我觉得妹妹cos这个绝对特别还原哦。」
「呸！变态！好了，要给你看的就这些了，出去吧！」冉萍在我身后推着我离开房间。
「等等，所以为什么要给我看啊？」
「没有为什么！快点走吧！我要睡午觉了，上午把我累的不轻。」
「好好好，我这就走，你好好睡一觉，我晚上可是还等着你呢，嘿嘿。」
一下午过去了，我在地下室布置好了今晚要用的道具。妹妹的房间里没啥动静，也不知道妹妹是不是睡了一整下午，一直到了吃晚饭的时间她才出了房间，她又换上了常穿的宽松t恤，同样还是没有穿裤子。
「喂！大变态，今晚不吃饭了么？」
「嗯，因为吃饭可能会影响今晚要玩的东西哦。」
「诶？那...现在就开始？」
「对啊，来，快来地下室。」
「那...我要脱掉衣服么？」
「来地下室脱就可以了。」
「那密码...」
「今天先暂时不需要。」
「诶？是吗？那好吧。」
妹妹跟着我走进了地下室。
「嘿嘿，妹妹会跳舞吗？」我关上地下室的门，坏笑着问妹妹。
「干嘛？大变态，问这个干嘛？」
「今天我想让妹妹跳个舞给我看。」
「诶诶？等等，你要...！」
我抓住妹妹的双手，然后拿绳子把她的手腕捆了起来，虽然冉萍一脸困惑，但是她并没有反抗。
「来，到这边来，要把拖鞋脱掉。」我绑好妹妹的手腕后，说到。
妹妹还是一脸困惑，但是仍然听话地脱下拖鞋，光着脚站在了地下室的地上。
房间天花板那根水管正下方，放着一块铁板，我把她牵到铁板上，然后把绑住她手腕的绳子挂到水管上，把妹妹的双手吊了起来，不过她的一双可爱的小脚还是结实地踩在铁板上。
这时，我拿来一个电夹，夹在了铁板上，妹妹恍然大悟一般地说到：「原来是这么个跳舞啊，真有你的！大变态！」
「嘿嘿，看起来妹妹已经看明白了啊。」
「唔！坏人！话说为什么没有脱掉我的衣服。」
「衣服嘛，我觉得妹妹穿着衣服跳舞更色情哦，不过内裤还是要脱的嘛，嘿嘿嘿。」
我一把抓住妹妹内裤两边，然后把她的内裤脱了下来。
「呜！坏人！大变态！」
「接下来另一个电极。」我拿着另一个电夹，来到妹妹面前，「就夹这里了。」
我掰开妹妹的双腿，然后把电夹夹在了一侧的阴唇上。
「好了，现在准备开始咯。」
我把之前用过的那个电刑机器，直接开到了7档，然后打开了电源。
「啊！」电源被打开的那一瞬间，妹妹惨叫了一声，然后立刻从铁板上跳了起来，双脚离开了铁板。
因为冉萍脚没有碰到铁板，所以电路断开了，她就感受不到电击，又把脚放回到了铁板上，但是只要碰到铁板，就会再被电。
「呜啊！疼疼疼！」妹妹再一次跳了起来，这一次她紧紧抓住天花板上吊着她的绳子，双腿蜷曲，整个身体都悬在了空中。
「哦，挺会玩的嘛，你以为这样就不会被电了嘛？」
我拿起鞭子，抽在了妹妹那白嫩的大腿上。
「啊呀！」冉萍被鞭子一打，吃痛失去了平衡，坚持不住双脚掉在了铁板上，结果又被电得惨叫一声，再一次抬起双脚。
「嘿嘿，我教你啊，在铁板上双脚交替着跳才行哦。」我扬起鞭子，又抽向了妹妹的大腿，直接打出了一道红红的印迹，「只要你把脚放回去我就不打了。」
「呜！大变态！大坏蛋！」妹妹一边呻吟着，一边慢慢把两只脚放回到铁板上。
这一次，她强忍着痛，坚持着没有抬起脚，一直坚持了一分钟左右。
「挺不错的嘛，不过我想看妹妹跳舞啊，你这么不听话可不行哦。」
我来到电刑机器旁边，然后一下子把档位开到了最大的九档。
「啊啊啊啊！疼疼疼疼疼！」妹妹终于在铁板上跳起了「舞」。
她先是因为电击的剧痛跳起一只脚，但是这时另一只脚落在了铁板上，接着这只脚又跳了起来，先前的那只脚又落了回来，这样不停交替，妹妹就仿佛在铁板上跳舞一般。
「啊啊！啊！」冉萍断断续续地发出着惨叫和喘息声，真的是诱人极了。
冉萍的t恤因为比较宽松，下摆是能轻松遮住下体的，但是当她每次从铁板上跳起时，她的衣服下摆都会跟着跳起，让她的私处时隐时现地露出，让一旁的我看的是如痴如醉。
「呜，哥哥，不行了！我，累死了，啊啊啊！」
「冉萍需要多锻炼锻炼才行嘛，这才跳了不到五分种，嘿嘿，要不是已经是最高档了，我还会再增加档位哦。」
「呜！坏蛋坏蛋坏蛋！啊啊啊~疼疼疼~」
逐渐的，她浑身上下都分泌出了汗液，在灯光的照耀下，她的浑身都亮晶晶的，仿佛发着光一般，非常漂亮非常可爱。她每一次跳起，头发都会跟着披散开，如银色的瀑布一般奔腾而下。
「呜，啊~不行了~放我下来~呜~」
「不行哦，还得继续。」
「呜~」
过了十五分钟后，已经可以明显地看出妹妹逐渐体力不支了，她的喘息声越来越大，惨叫声也越来越小，跳起的高度一次比一次低，抬起脚坚持不了多久就放了下来，一滴一滴的汗水滴在了铁板上。看起来妹妹已经是累坏了，我还是心疼冉萍，于是把电击器关掉了。
「哈~呼~」电源停掉后，妹妹浑身无力地挂在绳子上，大口喘着气，双腿发着抖，根本支撑不起她的重量。
「还好吧？冉萍，还想继续吗？」我把手放在开关上问到。
「不要不要不要不要了！累死了，我受不了了，别，哥哥，求你！」冉萍一脸可怜样地请求到。
「嘿嘿，好啦，不电了。不过说实话，冉萍你跳舞的样子真的很色情哦。」
「呜！大变态！」
我解开绳子，把冉萍放了下来，她立刻扑倒在了我的身上，我抱住妹妹，然后扶着她坐到旁边的自制「老虎凳」上。我递给她一杯水，她立刻把水喝了个精光，然后在长凳上坐了好久才缓过劲来。
「今天那就到这里吧？看妹妹已经累坏了的样子。」
「没...没事...我已经休息过来了，可以继续了。」
「额，可是，还要来跳舞吗？」
「不要不要！不要了！」
「那要啥？」我看着坐在老虎凳上的妹妹，突然想到，「对了，今天上午说想看妹妹白丝老虎凳的样子，妹妹能不能满足我这个愿望。」
「变...变态！也...也不是不行啦，就，就给哥哥看一次吧。」
「嘿嘿，谢谢妹妹哦。」
「哼！你去我房间里拿吧，我现在不想走路，不许偷东西啊！」
「偷东西？为什么要偷东西？」
「怕你偷我的内裤或者袜子什么的。」
「？？？？怎么可能啊喂！」
「好啦快去吧！」
妹妹房间里的袜子种类还不少，我特意挑了一双比较透的过膝袜，拿给了妹妹。妹妹接过袜子后，坐在老虎凳上，慢慢穿上袜子。
不过我说实话，一个半裸下体的女孩子，在老虎凳上穿白丝，这个场面实在是有那么亿点点色啊。
「好啦，可以了，瞧你那一脸痴汉样！哼！来吧，把我绑起来吧。」妹妹乖乖地把一双白丝腿往老虎凳上一摆，双腿整齐地放在了凳子上。
「好耶！」我拿出绳子，把妹妹上身脚腕还有膝盖都棒了起来，「既然上了老虎凳，应该上几块砖才好嘛。」
「大变态，随你上，上就行了。」
「嘿嘿，妹妹真好。」我搬起一块砖，垫到了妹妹的脚后跟下面。
「呜！」妹妹发出一声呻吟，同时闭紧了双眼。
「疼吗？」
妹妹紧闭双眼摇了摇头。
「那继续加了。」
我把第二块砖也塞到了妹妹的脚后跟下面。
「啊啊啊，疼疼疼~」妹妹轻轻地叫了出声。
"Are you already starting to feel the pinch?" I remembered that my sister's limit was four bricks, so I picked up the third brick and added more.
"Aaaaaah! It hurts! It hurts!" the younger sister started screaming.
After all, it wasn't torture; it was just playing around with a few bricks. There was no need to make my sister suffer so much. In the end, I pulled out the third brick and threw it on the ground.
After the third brick was removed, the younger sister stopped screaming and only let out occasional groans. Her feet were sweating profusely, the sweat soaking through her white stockings, making the already sheer stockings even more transparent, revealing pink skin underneath – it was incredibly erotic.
"Ranping looks really cute like this."
"You're such a pervert! Humph! Well... um, these socks have been worn for a long time, they should be replaced. You can destroy them however you want, it doesn't matter if you tear them to shreds or anything." The younger sister said, turning her head away.
"Really? That's great!" I excitedly picked up the thin bamboo pole that had been sitting in the basement for a long time and then whipped it into my sister's foot.
"Ah~ You bad guy!" A tear rolled down her cheek.
"Does it hurt a lot?"
"Um."
"It's supposed to hurt, right? The more it hurts, the more comfortable it should feel for your little sister?"
"No, no, ahhh!"
"Snap!" The bamboo pole struck the younger sister's white-stockinged feet again. Her little feet twisted back and forth in pain after being hit. It was really too erotic to twist back and forth and left and right in order to relieve the pain.
Each time she was hit, the little sister would scream in pain. After being hit more than a dozen times, the seam on her white silk stockings finally came undone, revealing her pink soles.
I grinned mischievously and tore Ran Ping's stockings even wider from the tear, exposing her toes and heels.
"As expected of a foot fetishist! Humph! You big bad guy!"
"Hehe, having Ranping around is really great. Ranping is the cutest girl I've ever met."
"Huh? I... Hmph! What's the point of your praise? I'm not happy at all."
"Whatever." I swung the bamboo pole again and struck Ran Ping's bare soles, and Ran Ping's screams echoed in the basement again.
Nearly half an hour passed like this until I was exhausted and finally untied my sister. After beating her for so long, the soles of her feet were swollen and red, with dozens of red welts overlapping, but thankfully there was no bleeding. The sight of her feet, bound to the tiger bench and tortured with bricks under her heels, along with the tattered white stockings, was truly astounding.
"Are you alright? Can you still walk?" I asked after untying my sister.
"No way! Brother, hug me!"
"I couldn't have asked for this more than I could have." I stepped forward, picked Ranping up in my arms again, and carried her to the sofa in the living room.
"Okay, bring me the clothes. Also, hurry up and cook, I'm hungry."
"Okay, okay, I'll make it for my little sister right away."
Ran Ping's Diary
August 26
Today my brother said he wanted me to dance for him, and I was confused at first, but then I saw the metal plate with electrodes on the ground and I understood everything. I'd heard of this before, but I'm still really looking forward to trying it out for myself.
My brother clipped the electrodes to my genitals. After the electricity was applied, I put my foot on the metal plate, and instantly felt a sharp pain that spread from my toes and genitals throughout my body. Although it hurt a lot, it was also very stimulating.
Later, I actually did what I had read in the materials, jumping one foot at a time on the iron plate, "dancing" like that. There were people watching, and I felt so ashamed.
After a while, I started to get really tired, truly exhausted. My legs felt like they wouldn't obey me, and I kept jumping on the metal plate. I was so tired that my vision was blurring, and I almost thought I was going to faint. Luckily, my brother turned off the power in time. After turning off the power, I realized that I was covered in sweat, and my clothes were soaked.
Then I was put on the tiger bench again. Just like before, it still hurt as much as ever after the bricks were placed on me. Ouch.
