Puberty hit me hard and I was constantly horny. 2 years older than me, my sister and I were close. So when she started being sexually active I couldn’t help but notice things change. New skimpy panties, hairs around her bikini bottoms, and asking her what a boner is. Seeing her in a new light as a woman with boobs and a pussy sends me on a journey. As the only girl I saw regularly and live with made her my first sexual fantasy.
It was when my older sis started wearing thongs and skimpy panties that I began my panty fetish. I can’t explain why I did it, my primal instincts took over. I had seen naked people on the computer before and had been jacking off for a while when it happened. I always thought girls underwear was sexy when I’d walk by Victoria secret or look online at ladies. I knew early on that I was a Panty boi, but kept my fetish secret from my ex girlfriends. One saw a yellow thong in my trunk and questioned me about it but I said I had no clue. Would she think I was a sick pervert? Would she just move past it? Or would she want to be part of it? I’d love her taking off her favorite pair and having me try the dirty panties on for her.
I remember seeing my teachers white lacy thong when she bent over to grab some trash as i stood close behind her. She was young, pretty thicc and a redhead with pale skin and my first crush. Time froze as her thong rode high above her jeans and disappeared between the top of her slightly exposed cheeks. I spent all class hopping shed bend over and I could see her panties. A few times I got lucky seeing her see through black bikini style panties or thong and I’d jerkoff thinking about her. Later that same year, we had a free dress day and didn’t have to wear out uniforms. This girl that I thought was one of the hottest in the class wore jeans and a short shirt. As she leaned forward in her desk I noticed a bright teal string. She was wearing a small g-string thong that was skimpier than I’d ever seen. She unlocked my love of colored panties and I wondered how she could be comfortable in them. Her parents let her wear this tiny underwear that covers nothing with them between her cheeks, rubbing up against her asshole. I got horny thinking about the slutty panties and was curious how they’d feel to wear.
Clear as day, my first time holding a thong happened a year later. I was naive and curious, so when I was doing laundry I saw a bright article in the pile. I picked it up and realized it was a thong made of lace. My sister and mom hadn’t worn this type of underwear before. Maws my sister wearing these and doing things with guys? I grabbed her dirty thong from the laundry and my cock took over. There was a large crusty spot located at the bottom of the front but it wasn’t pee. I lifted it close and inspected the crotch, noticing a strong musty stench that for some reason I couldn’t stop sniffing.
When I realized her pussy had been rubbing against the thong all day, it made me horny. She was my sister but smelled good so I slowly licked the stain, tasting pussy for the first time I ran to my room, shut the door, dropped my shorts and laid down. I started stroking my already rock hard cock picturing her wearing the thong. I held the thong to my nose, her dirty scent instantly made me hornier than I’ve ever been. I regularly stole and jacked off with her panties, pink brand thongs, see through bikini style, and even a g-string.
One time I was naked and out of no where wondered how girls wore these skimpy underwear I took her thong and slid it up. My stiff cock poked out the top but the soft material cupped my balls. It felt weird at first, I pulled the thong between my cheeks and could feel it rubbing my asshole. I probably tried on every pair she had and came in most. I’d put the dirty panties back in the pile after but stretched and covered in my cum, she had to have figured it out.
Years later we had a family vacation and as the fam swam in the pool I was diving wearing goggles. I went to scare my sister but as I got close I noticed short hairs around her bikini bottom. She hasn’t shaved in a bit and I got hard thinking about her bush. Later in our room she went to shower first. Sneakily I noticed the bathroom door at the condo had slits you could see through. I knelt down and caught an eyeful of her backside as she lowered her jeans. I never noticed before but she had a nice round ass. She turned and sat on the toilet.
She had a thick brown bush and small perky tits with good sized pink nipples.
She wiped her pussy a few times and entered the shower.
I was hypnotized seeing my first naked girl in person, getting hard popping a tent in my shorts. She got out and started drying off with her back to me. I watched her ass jiggle as she worked down to her legs bending over so her hairy pussy peeked out between her thighs. Watching for a while as she rubbed lotion all over her body I stopped watching before she got dressed. After. I realized her panties always had big stains because her bush catches her juices and she must be horny a lot.
Even when we were in college we used to share a bed when we visited our grandparents. I hated the saggy bed and had to jerk off in the shower when I could. One night she turned the lights off and went to sleep while I watched a movie on my phone. She wore tight shirts but never a bra to bed so I could see the outline of her small boobs and nips every night before sleeping. Her nips started soft usually but I could see them get hard slowly until they poked out and were surprisingly big. She had to know she was teasing me and getting me horny
An hour later I couldn’t sleep and knew a good orgasm would help but the bathroom was loud. I slowly laid on my back and slid a hand to rub my shorts and growing chub. Up and down, I was getting semi hard, but was too nervous to pull out my cock. Stopping to make sure sis was asleep and hadn’t moved or anything with her back to me. Imaging her naked pale ass and hairy slit from the shower, I was getting close. Fantasizing how hot it’d be seeing her put on one of her slutty thongs. How her wild bush escapes the small front and how the thin back wedges against her asshole between her jiggly cheeks. I started getting bolder and slipped my cock and balls out my shorts but kept my shirt covering it. If she did wake up would she say anything or pretend to sleep as I finished. She was a foot away from my dick and I fantasied about her masturbating next to me and how she’d rub her pussy. I wanted to eat her out getting her pussy juice and smelly scent all over her pubes and my face.
I reached under my shirt and gripped my cock slowly stroking up and down. I was close to finishing but tried to keep it steady to not rock the bed. I couldn’t tell if I was moving too much but I kept going as my orgasm slowly built up. Suddenly my first load shot out making me gasp a little. It was a big load making me breathe hard. I left the pool of cum on my belly under my shirt and fell asleep. I hope she heard me stroking and pictured what my cock looked like hard.
Slipping a hand quietly down under her shorts rubbing her wet pussy through her panties.
