Hi. My name is Sam and I just got home this past weekend after completing my junior year at college. It was Monday morning and I was hoping to catch up on some sleep after partying all weekend with my friends whom I hadn't seen in a while. My parents would be at work and my sister, Megan, would be in school.
At 9 o'clock, however, my mom knocked on my bedroom door to wake me up. She had taken the day off of work as Meg for some reason didn't have school today. Why don't I remember getting random days off when I was in high school? Anyway mom said she was going to take Meg to the cell phone store today and she wanted to know if I cared to go with them. I figured I might as well since I was already up. I needed a new case for my phone and I thought that I could probably get mom to spring for it. Meg had just turned 18 and, although a couple of weeks late, mom was going to get her a new iPhone.
I hopped in the shower and when finished grabbed a quick breakfast, brushed my teeth, and was ready to go. We arrived at the store shortly after it opened. Megan was so excited. She was bouncing around the store looking at all the new phones and cases. I had never paid much attention to Meg. She was always trying to bother me when I had friends over. I didn't want my sister, who is three years younger than me, pestering me all the time. She was slow to develop, tomboyish, and a general pain in the ass.
Today it was different. Meg had on yoga pants that showed off a nice, round ass. She was also wearing a hoodie from my university that I had purchased for her birthday. Even though it fit loosely on her I could make out her tits straining the fabric. I noticed she was also much taller than I remember and her dark brown hair was now flowing over her shoulders and partly down her back. And she was cute too! Damn, how did she grow up all of a sudden? And why was I looking at my sister this way? I even noticed a couple of the workers checking her out. Fuck them. She was my sister and they better leave her the fuck alone and stop ogling her.
Meg picked put out her phone and while they were activating it I found a case for my phone and put it on the counter. I showed mom the rip in my current case and she said "That's fine. I'll take care of it honey."
"Thanks mom. Love you" and I gave her a kiss on the cheek. I kept checking Meg out the remainder of our time there. On the way home she sat in the back but I kept myself turned her way so she could be included in the conversation. My approach to my sister definitely needed some changes based on her new...developments.
I couldn't get Meg off my mind. The rest of the day I kept thinking about how hot she was. I knew it was wrong but didn't care. I needed to find out more. Did she have a boyfriend? Had she discovered sex? I needed to know this and more! What I needed was a plan. So I came up with one.
Step one was to do a little investigating. Tuesday mom went back to work and Meg went to school. She only had about a month left in her senior year of high school and then she would be off to college herself. I decided the first thing I needed to do was to check her computer. She didn't have it password protected because our parents insisted they be able to check our computers whenever they felt necessary. In reality they checked them when we first got the computers but their check-ups on us became less and less frequent. I checked Meg's browser history but it was empty. I took this as a good sign. If she was deleting her history than she had something to hide! My parents aren't tech savvy so if they checked and saw no history they wouldn't have thought anything of it.
I, however, was going to school to become a programmer and I knew all the tricks. Nothing is ever really deleted and it didn't take me long to find what I was looking for. There were a lot of sites to sift through. I picked a random day and had a look. Most were related to her completing her schoolwork and there were also multiple listings to some pop culture sites and of course social media. I dug a little deeper until I found the dirt. Porn. My little sister had looked at porn. It was a video site and the videos she had viewed were all straight couples fucking videos. I searched back a few days before that and found some more. Mostly similar videos were listed but there were also 3 lesbian videos. Holy shit Meg, what were you up to??? I started getting hard just reading the titles which were all explicit so it's not like she could have clicked on them in error.
It felt like the room was starting to get warm. I was sweating but excited. I switched my search to the past few days. There wasn't much showing for Saturday or Sunday but there was for last night. She had really watched some porn last night. There were a few amateur couples having sex. There was a young girl blowing an older guy and then there were 3 others. All three had something in common. Sisters and brothers fooling around and having sex. Oh my God. Are you fucking kidding me? Did she have feelings like this for me? I clicked on one of the videos and started stroking my now rock hard cock. This girl sneaked into her brother's room, climbed onto his bed, reached under the covers, and then started blowing him. He then swung her legs over him until they were in a 69 position and were getting each other off. I lowered my shorts down all the way and pulled off my t-shirt. I continued to furiously stroke myself while watching the video and as the young siblings were simultaneously cumming on screen I shot a massive load onto my belly and chest.
I cleaned myself up and made sure to delete everything I had done on Megan's computer. My next step was to find out what she was doing with all this porn. She had to be masturbating, right? I hacked into her webcam which would not only give me good view of her sitting at her computer but also a straight shot of her bed with the computer chair only slightly blocking things. When I was finished I could view her cam through my phone or tablet whenever I wanted to and she would be none the wiser.
As part of my plan I knew I had to pay a lot more attention to Meg. I greeted her when she got home from school Monday and asked her about her day. I tried to hang around her a lot more and just talk and listen to her. I also wanted to be playful so I would flirtatiously rub against her or touch her throughout the day. I watched her through her webcam as soon as she turned in for the night but there was nothing interesting to see. She had gotten changed in the bathroom and went to bed early. No action. Wednesday came and went as did Thursday. I was continuing to flirt with her and she started flirting back a little more each day, On Friday we were playfully punching each other and goofing around a lot more. Our parents both said it was nice that we were getting along for a change. That night she went to bed around 10:30. She looked great as she always seemed to now. She wore a snug t-shirt and shorts to bed. I said goodnight to everyone and turned in around the same time. I turned off my lights, grabbed my tablet and got under the covers. I pulled up the cam and watched Meg in bed.
Although the cam doesn't work all that great at night I was able to see what was going on thanks to some ambient light from her clock as well as her new phone which she was holding in her left hand while lying in bed. After a few minutes I saw her turn the phone as you would to view a video. Next she lowered her blanket off of her. Meg then started rubbing her left breast with her right hand. She was pinching her nipple through the shirt. Next she put her hand under her shirt and continued rubbing herself. I didn't even realize that I was now rubbing my cock through my shorts. The video must have ended because both hands were back on her phone. She found another video to watch and she got right back to it. Meg started rubbing her crotch through her thin shorts. I could see her lifting her butt off the bed a bit as she got more into it. Meg then reached under her shorts and really started to rub her naked pussy. She was rubbing faster and faster. Every once in a while she would raise her hand to her mouth and suck on her fingers. It was so fucking hot. She kept going until she put her phone down, running one hand roughly over her tits while the other one stayed on her pussy until she came. I put down my tablet and a few seconds later I also came. It was unbelievable.
Mom had to work Saturday since she took Monday off but she got home early in the afternoon. She said since I was home she and dad were going to go away for the rest of the weekend. They both worked a lot of hours so this would give them some alone time. Mom spent a couple of hours packing and getting ready. After dad got home he changed into some comfortable clothes and grabbed a few things for his weekend getaway. He then gave me $50 and said this was so that Meg and I could go out a couple of times to get something to eat. Otherwise there was food in the fridge and we could grill some hamburgers too if we wanted. They kissed us goodbye around 6 and told us they would call or text us often to make sure all was ok.
I couldn't believe my luck. This would be my big chance to see how far I could push things.
"Hey Meg, did you have any plans for tonight?"
She said no so I suggested that we go out and use some of the money dad left for us.
She said "Oh is big brother asking me out on a date?"
I told her she could call it what she wants but we should go out and have some fun. She agreed and I said to be ready in an hour. She was ready to go on time, wearing a dark blue shirt I hadn't seen before. It had a v-neck cut and showed just a tiny bit of cleavage. She also wore some tight jeans. I had on a nice shirt and a new pair of jeans also.
Meg said "Looks like I'm going out with a hunk tonight."
I responded that I needed to look my best if I was going to be taking out such a beautiful young woman.
