I began to expose myself occasionally to her ‘accidentally.’ I’d have my flaccid penis hanging out of my pajamas and walk by at a time she would likely be looking. I’d pull my towel off right before I entered my room, in clear view of her.
When I was in high school I started to become quite attracted to my little sister, who is two years younger than I am. It was no big deal at first. She was cute and I assumed it was normal and temporary. I didn’t think much of it. Then one day when I was home on break from college I happened to notice a pair of purple cotton panties in the hamper and I sniffed them and got so horny that everything changed. I was now obsessed, but my family and my sister are all very conservative religious people, and i would be disowned if anyone found out about my secret.
The second semester of college I thought about her every day. I hooked up with other girls, but eventually found myself virtually unable to come until I visualized my sister Marie moaning underneath me, rather than whoever it was I was actually with. I kept in contact with my family on video messenger, and I always hoped to get a chance to see Marie, but I tried my best to act normal when she did pop in. I couldn’t help but say things like “I’m sure the boys are lining up down the block to be with you,” and she would take it as a brotherly nice thing to say. Meanwhile my hand would be on my cock out of the screen. When classes came to an end, I was thrilled to be heading back home, even though I knew I could never do anything but fantasize.
After a couple weeks, however, I found ways I could act out and tease around with my fantasy in a relatively safe way. Her bedroom was right by mine and in between mine and the bathroom. I began to expose myself occasionally to her ‘accidentally.’ I’d have my flaccid penis hanging out of my pajamas and walk by at a time she would likely be looking. I’d pull my towel off right before I entered my room, in clear view of her. I would wait in my bedroom with the door half open waiting to hear her moving around and as she opened her door I would have my underwear at my ankles and pretend to pull them up quickly. All of these were portrayed as inadvertent and innocent and unlikely to cause any confrontation or suspicion.
I got bolder with her panties, too. Based on my trips to the hamper I could tell her purple cotton briefs were her favorites, as well as mine. One day I pulled them out of the washing machine during the cycle and stretched out the material on the crotch and ripped a couple threads on the seam. Sure enough, a couple days later the purple panties showed up in the hamper, stretched and with a nearly dime size hole. But she still wore them!
A few days later I went through her panty drawer when she was away from home and found out she must be wearing the purple ones. That night I took it to a new level. She slept very deep at night, and had a penchant for sleepwalking. I had tested the deep sleeping a few nights earlier by walking into her room and trying to wake her up with some pointless question to ask her if she did. Even with lightly tapping her face, grabbing her arm, and trying to roll her over she was sound asleep. Her history of sleepwalking also gave me a sense of security because I’d seen her be completely confused and not know what was going on in the middle of the night, so I could always suggest it happened again if I was caught in a precarious
That night, I snuck into her room, removed her covers slowly, but was disappointed to see she was wearing a pair of pajama shorts and a matching shirt. The shirt was pretty tight and would be hard to adjust, but the shorts were actually very short and had wide leg openings and I could get a clear look at her panties if i moved them aside. I had a tiny little flashlight and made my move, terrified but as aroused as I’d ever been. When i pulled the shorts aside, her panties bunched up a little. Those purple panties could be moved aside, too, I realized. just as i went to do it, she shuffled in bed resulting in me getting a clear look up her shorts at those panties. Once i was sure she was still asleep I carefully pulled the panties far enough to the side to see her puffy outer labia and gash, covered in fine blonde hair. I was so horny I could barely control myself, but this is as far as I could ever go. A couple weeks before this she had jokingly told me to pull my shorts up or buy myself a trimmer. It wasn’t a big deal then, but I was getting reckless and knew I had to stop. This was as far as I could go. I went back to bed and jacked off,
As years went by my obsession never waned, and I still got off on her panties occasionally, but never did any of those things again. I had pushed the limit and not been caught so I just kept my fantasy to myself. She is now happily married to a conservative Christian man and they live a life very different from mine. Everything is going well and they are happy and blossoming. A couple months ago they moved back to my parents house while they find a new home to buy. My parents live an hour away from me, and last weekend the whole family decided to spend the weekend there for my brother’s birthday. He, his wife and two kids, my sister, her husband and my parents all were there.
The first night was just a typical family birthday night. A big meal, a couple board games, catching up on everyone’s current affairs. Everyone changed into their cozy clothing after dinner, and I spent a fair amount of time sneaking careful glances before deciding Marie wasn’t wearing a bra. I could faintly make out the darker color of her nipples through her long shirt a couple times, or perhaps it was a figment of my imagination. Regardless, people faded away to bed pretty early, but I was restless.
I was on the couch watching TV, and at around 1 AM my sister came out of her bedroom to grab a glass of water wearing a thin purple nightgown. It was modest, but I could tell she was wearing nothing underneath, and i wondered if she had just had sex. My dick got hard again as she smiled and said goodnight, and went back to bed. My mind was taken back to several years ago and her 18 year old body and those purple panties. I remembered how I used to expose myself to her. My mind went places it shouldn’t have gone. She is a nurse and I knew she worked at 5:00 AM at the hospital the next morning. Four hours from now. I made a plan that could end horribly, but committed to it. After a sleepless night of anticipation I quietly went to the bathroom by her bedroom at 4 AM, closed the door most of the way but didn’t latch it, and kept the light off. I got naked and sat on the toilet and started playing with myself.
About ten minutes later, I heard her muffled alarm from the next room and I braced for what was next. I closed my eyes and leaned back, pretending to be oblivious to anything as she entered the room and turned on the light. “Oh my god, Marie!”, I quietly screamed in pretend surprise.
“Why does this not surprise me?”, she said almost nonchalantly
“What do you mean? Shut the door!”
This was not what I was expecting. I was so confused as she shut the door, but didn’t leave in horror as I expected. My hand was still wrapped around my engorged member as I asked her what the hell she was doing.
“This is hardly the first time I’ve seen you naked, Grant. I have to get ready. You know I work soon. Better question is what the hell are you doing?”, she said calmly.
“I didn’t know what time it was, and even though it’s none of your business, I woke up with a boner. Didn’t really have a choice,” I snapped back
“It wouldn’t surprise me if you set this up on purpose just to show me your penis again” she said
“Again?” I barely squeaked out.
“Grant, I saw your exposed dick several times when you moved back from college. It was a little weird, but I knew you wanted me to see you. I never said anything, because I didn’t want to embarrass you."
“I’m so sorry” I repeated meekly as I started subconsciously stroking myself again.
“I’m such a creep,” I continued. "I just always wanted to see you naked, and that was the next best thing, You know I never would have hurt you, right?
“Grant, just calm down. We were kids. It’s natural to be curious, I guess, even though it is kinda weird. You’ve grown a bit since then” she chuckled nervously.
“Please don’t tell anyone” i nervously pleaded
“I wont’t tell anyone, but you can’t jack off in front of you little sister with her husband in the next room…or ever for that matter. It’s messed up.”
I was so deep into this mess, and couldn’t possibly feel anymore shame than I already did at this point so I quietly asked her,
“Can I please just see you naked? You’ve seen all of me and know my darkest secret. I’ll never tell a soul.”
“I took a vow when I got married, and you’re my brother. This crosses so many lines. It would be so inappropriate.”
“Okay, I’ll be gone before you get out of the shower. I’m sorry, I’ll make up an excuse to mom and dad why I had to leave, I won’t bother you anymore. Please forgive me”, I said in absolute embarrassment and despair.
I stood up and took my hand off my still throbbing cock and was about to walk toward the door when she suddenly leaned against the vanity and pulled her nighty swiftly up and off and tossed it at me.
“Fine. One look. I hope this helps, because it’s never happening again.”
I knelt in front of her and looked up at the most beautiful sight I’d ever seen. Her C-cup breasts capped with dark, silver dollar-sized areola and rock hard nipples gave way to her trim torso down to her prize. Her plump outer labia were spread just enough because of how she was positioned that the pink inner flower was partially visible, and appeared to be moist. She had neatly trimmed, fine, blonde pubic hair that looked almost like peach fuzz. I immediately started stroking myself again. I asked her to turn around and she reluctantly bent over the sink and I could just barely see her bum hole and could now clearly see she was wet. I pulled out my phone as she turned around, and told her, rather than asking, that I was going to take a picture of her, but not include her face. She rolled her eyes, but assumed her original position, this time with her legs slightly more parted, giving full view of her exquisite pussy. I snapped several pictures, along with a little video, and showed her to make sure she was ok with it. She told me to just get out and forget it ever happened. Just as she said that I finally exploded without any warning, almost all of my roping semen covering her stomach and navel, even into her pubic hair. I reached for a towel to clean her but she cleared her throat and told me that was it. “Next time you jack off, keep it to yourself. Use a sock, not your sister, as a cum catcher. This stops now. I snuck one last look at her heavenly body, and got out of the bathroom.
By the time she was back from work I was at my house, which is an hour away. I was still so horny and a bit bolder now. I attached the picture I took of her ass and pussy bent over the sink in a text and captioned it, “Is Aaron ready to assume the position and take care of this tonight?I got a reply within seconds.“Grant, Aaron treats me with respect. He loves me with his eyes to mine. He doesn’t just take me from behind like a deviant! You need to behave. You got your picture, which I regret. Just leave it alone please!"
I waited only a minute or two before I texted her back, “if I was Aaron I’d start by bending you over the counter, ripping your pants off, eating your pussy and ass until you screamed. Then I would make my way to all of this.”
I attached the photo she didn’t know existed. Full frontal, portrait mode, her face clearly visible, and a cute pouty look on her face. An objective observer may even suggest she looked aroused. She called Immediately, screaming that I delete the picture. When I told her there were more than just that one, and some video, she told me she was coming over to personally make sure I deleted them. She will be here in less than an hour. I zoom in on the picture of her ass hole and slide my pants off. My life has gone off the rails. I have no idea what to expect.
