Home alone with my older sister [M/F][Incest]

This took place after I graduated high school. I was 18 and my sis was 21 at the time. My older sister and I were not particularly close. She was nice to me and we talked but we never really hung out or had fun together. It was just a pretty standard brother-sister relationship. This would all change one summer.

It was the summer vacation of the year I graduated so school was out and my sister was home from university. My sister and I are of Hispanic descent. She is 5’6 with long black hair and tan skin. We share similar facial structure in that we both have high cheekbones and slim jawlines, we have the same tan skin, dark hair color and the same brown eyes. And of course, we both share the typical Latino look. Basically you could tell at first glance we’re siblings. I’m notably taller than her, being 5’11 but that’s more or less the only “unusual” difference. She was attractive and was a popular girl when she was in high school but I didn’t really take note of it, dirty thoughts never crossed my mind regarding her. That is until the summer she came over to visit.

It was a month into summer break. I got accepted into a University 2 months prior so I was chilling since then. My sister was visiting from her Uni around the time I got accepted so she had gotten used to living at home again. Both my sister and I are decently athletic. I played soccer for all of high school and my sister ran track. My sister used to go on runs every day really early in the morning as part of practice for the team but she carried on doing it even after she graduated. One July morning I happened to wake up early to see a soccer game. Both my parents were still asleep but right around the time I woke up my sister had just returned from her morning run. I was could hear her bathroom’s shower turn on and felt jealous that she had a bathroom attached her room. I got up to brush my teeth, still wearing nothing but my boxers and walked past her room when something caught my interest.

Her bedroom door was open and her running outfit was strewn across her bed. Instinctively I walked into her room, knowing she was in the shower and couldn’t hear me. I looked down at her bed and examined the clothing. Her running outfit consisted of a grey Nike sports bra with a pair of mesh track shorts which were quite small, probably from a couple years ago. I don’t know why but I picked up the shorts and the back of them were soaked from sweat. At first I winced a bit at the touch but something inside the shorts attracted my attention. I pulled it out and in my hand was a sleek black thong. Unlike the shorts, it was entirely soaked and I could tell it was freshly worn. I’d be lying if I said I didn’t sniff it. I felt disgusted with what I was doing, I had never done anything like this before, but at this point I was immensely turned on. That’s when I heard the shower turn off and the bathroom door unlock.I was royally screwed as I knew I couldn’t run out of the room in time. I didn’t know what to do so I just shoved the thong down my boxers.

The door swung open and my sister was standing there with a towel wrapped around her, with her long wet hair going past her shoulders.”What the fuck are you doing in my room this early?” she asked, not expecting to see me. “I was gonna borrow your laptop charger but I couldn’t find it, I wanted to watch the game today” I quickly replied. I was trying my best to hide my boner but it was glaringly obvious, especially with only my boxers on. Her towel barely went past her hips, just enough to cover her chest and ass.”Why’re you always stealing my shit?” she asked agitated. I was relieved she believed my lie. “I’ll let you use it but give it back as soon as you’re done” she said. Still wearing her towel, she went over to the nightstand beside me to retrieve it. My family was fairly comfortable with attire like this in the morning. It was common for us to sleep in our underwear and if one of us just showered or came out of the pool, we’d walk around our rooms in a towel until we dried off, just as long as we showed no nudity. “The charger is right here next to you on the shelf, you must be blind” she joked. The charger was on the bottom shelf of the nightstand, easily noticeable to anyone who would be looking for it but obviously that wasn’t why I was there. I gave a nervous chuckle but I was practically sweating at this point. I was just trying to get out of there. That’s when I got quite the shock.

My sister bent down to get the charger from the bottom shelf when her towel which was already tied short, rode up her back. For a split second I got a clear view of her asshole and even her pussy from behind. Almost instantly however she pulled the towel back down to cover up, but didn’t say anything. My fading boner quickly came back. She quickly grabbed the charger and straightened back up, acting as if nothing happened. “R-remember to give it back” she said nervously. I pretended I didn’t see anything and simply replied with an “okay”, turning around and swiftly leaving her room. Needless to say I was not expecting that. Instead of going to the bathroom to brush my teeth like I originally planned, I went straight to my room to jerk off.

I locked the door, threw the charger in the corner and yanked down my boxers. That’s when I realized I still had her thong that I stuffed into my briefs while in panic. I regret to say that this made masturbating all the more pleasurable. I jerked off with the panties, rubbing the nylon material against my shaft. Occasionally I would take a whiff of the sweat stained material. My lust clouded how fucked up this was. The scent of my sister’s thong was strong, and aroused me even more. The brief moment of my sister’s ass and pussy exposed played on repeat in my mind as I imagined myself grabbing her waist and sliding straight into her tight body. My cock began throbbing and I blew my load into the thong. Naturally, I instantly felt sick for what I had just done. I reflected long and hard about it, initially in denial but I realized I wanted to see more of my sister. I had never checked her out or ever really looked at her body in a sexual way.

These thoughts aroused me even more and the next few days of my summer vacation went by with me sneaking into her room every morning and jerking off with her panties while she was on her runs. I ended up checking her out a whole lot more as well. Her body was athletic and lean. Outside the house, she’d tie her hair up in a ponytail or a bun but at home she’d always have her long black hair loose and flowing past her shoulders. Her chest was relatively modest, but her tits were perky and sat up. From the glimpses I caught of her in her running gear, I’d say B-cups. Her stomach was flat and toned from constant exercise and her arms were thin. Her ass was my favorite part about her. It wasn’t very big but it was perfectly round and her small, tight running shorts would ride up her crack every time she took a step in them. Her legs were also quite nice. Not very thick but they were long and complimented her body well. Occasionally I would spot a cameltoe but I never got good views like this often as she would only wear her running gear in the mornings, after which she changes into usually a baggy t-shirt and sweatpants.

My obsession grew but I’d pretty much accepted that jerking off in her panties would be the most I’d achieve. Little did I know, there was much more to come once we were home alone together.

============================================================================

This is my first time writing about sexual encounters. Yes, this story did happen for those wondering. I exaggerate some bits but for the most part what I describe is a retelling of events. I know this story might be a bit taboo which is why I made a throwaway account to tell you guys about it. If you enjoyed, please let me know as I want to hear what you guys think and I hope to write part 2 very soon.
