When I was about eighteen, 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.
In 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 just a nice brotherly 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 of 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 this was portrayed as inadvertent 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 of threads on the seam. Sure enough, a couple of 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 situation.
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. Because of my little alteration, 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 labia, 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 of weeks before this, she had jokingly told me to pull my shorts up or buy myself a trimmer as I stood in her doorway wearing two pair of spandex compression shorts to hold my hard dick against my thigh, with my pajama bottoms sagging low enough to expose some pubic hair. She didn’t make a fuss about it, 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 of 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 a couple of weeks ago, my mom arranged for the whole family to spend the weekend there for my brother’s birthday, using it as a convenient excuse to get everyone together. My brother, 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 of 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 of times, or perhaps it was a figment of my imagination. Regardless, I was horny, frustrated, and restless. As everyone slowly tapped out for the night and went to bed, I stayed in the living room.
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 jealously wondered if she just finished having sex with her husband, Aaron. Probably not, on second thought. And if so, probably just boring, quick missionary that didn’t make her cum, I reassured myself. My dick was getting hard as she smiled and said goodnight, and went back to bed.
My mind was taken back to several years ago and her eighteen-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 everything as she entered the room and turned on the light. “Oh my god, Marie!” I quietly screamed in pretend surprised.
“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 behind her, rather than stepping outside the room. 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 heck 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 tried to stick to my guns. “What are you talking about? I don’t remember ever being naked in front of you.”
“Oh. My mistake. I guess the fly on all your boxers and pajamas you owned just randomly refused to stay closed. And the latch to your bedroom door was broken too, I assume. That must be it,” she said sarcastically. “The first couple times your towel was open in the front as you walked past my room, I didn’t think much of it, but, come on. How dumb do you think I am? After the fourth or fifth time your penis was hanging out as you stood in my doorway telling me to sleep tight, I knew you were showing me on purpose. I never said anything because I thought you’d just get over it once you found a girlfriend or something.”
I was obviously caught, and my whole body felt numb as I sheepishly admitted my perversion. I’m so sorry,” I muttered as I started subconsciously stroking myself again. “I’m such a creep. I couldn’t help myself. I just always wanted to see you naked for some reason and you seeing me was the closest thing to it, aside from putting a camera in the bathroom or something. I’m so fucked up.”
“Relax. I know how horny boys get,” she replied nervously.
“Please don’t tell anyone,” I pleaded desperately.
“I won't tell anyone, but you can’t jack off in front of your little sister while my husband is sleeping in the next room. We aren’t teenagers anymore. This is too much.”
I heard her words but my hand was on autopilot slowly stroking my throbbing cock. I was so deep into this mess, and couldn’t possibly feel any more shame than I already did at this point so I quietly asked her. “Can I please just see you naked? You’ve obviously seen all of me and know my darkest secret. I’ll never mention it again. I just have to see you,” I pleaded shamefully as my eyes filled with tears.
“I took a vow when I got married, and you’re my brother. This crosses so many lines. I’m beginning to lose my patience. Please go to bed so I can get ready for work.”
There was nothing else I could do or say at this point, other than exactly what she asked me to. “Okay, I’ll be out of the house 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 despair.
