My sisters christmas thong!

PREQUEL: Since i was about 14, i have been smelling my younger sisters panties. I am now 24, and she's 19. So i have smelled and cummed in them for about 10 years now. I especially love thongs, but she has never had many of them. She got her first one when she got her first boyfriend at about 15. Before she moved away for college, i had never seen more than 3 different thongs, and i was only lucky enough to find them dirty a handful of times. When she hit puberty, her panties used to get really wet and sticky with her juices. I loved going to the bathroom just after she had taken a shower and find her fresh panties she just had taken off, still wet with her pussy juices. A few times they were so wet with very thin liquid, i am absolutely certain she must have masturbated with them on! Just the thought of it makes me crazy! I licked them quite a few times when they looked especially creamy and were not too dirty. Very often i came in them, and then placed them on the bottom of the laundry bin. I stopped cumming in them as we got older, being afraid of getting caught, as she now could figure out what it was if she found them filled with my cum. When she lived at home, i usually had a few of her dirty panties tucked under my bed or pillow, ready for a sniff to get me going. THE STORY: When i was wanking the other night, i heard her in her room next door. I was imagining her fingering herself too. I'm not sure if i really heard anything, but it sometimes sounded like wet noises. Anyways it got me really horny, so i found her old panties that i had saved, and having them against my nose with her in the room next door made it so hot! I had my best couple of solo-orgasms for a long time that night. When I woke up the next morning, i was kinda hard from a hot dream about her. I was about to lick my sisters pussy, but ended up almost getting caught by our parents. Unfortunately i woke up before i got the chance to taste her delicious shaved pussy. I went straight to the shower. I thought i was too tired from the night before to wank off again, even though i had that hot dream. After i was finished in the shower, i went to the laundry room with my dirty clothes and towel. There on the floor was the sexiest little thong from my sister! It was pink and very cute. Unfortunately the door to her room is just opposite to the laundry room, and she was in her room with her door open and saw me throw my clothes in there. So i had to leave it there... I went back to my room but couldn't think of much else than getting a whiff of that dirty thong! A few minutes later, i heard my sister going up the stairs. I went straight to the laundry room, making sure i didn't hear anyone coming down the stairs. I quickly picked up the panties and went straight to the bathroom. I unfolded them and was shocked by how dirty they were! They were even too dirty for me to consider giving them a lick! Her whole gusset was covered in her juices! My dick immediately got rockhard! I pulled my dick out and put my sisters dirty thong straight to my nose, the smell was incredible! I wanked like there was no tomorrow while i smelled the pussy stains in her thong. I watched myself in the mirror with her hot thong pressed against my face and pussy juice peeking out. It was so erotic, there is something special about the cuteness of pink underwear covered in light yellow stains, so visible yet cute at the same time. I kept stroking and stopping for a few minutes teasing myself, until i finally couldn't take it anymore and came hard, i didn't even bother trying to aim anywhere, so my cum went all over. My stomach, thighs, the faucet, the wall, the mirror, the floor, there was drops of cum everywhere! I am lucky enough to be able to cum multiple times. I just kept going and came again, squirting even more cum, with her panties still pressed against my face, smelling her pussy, imaging it rubbing against her wet clit and pink pussy lips all day. Imagining seeing her little pussy mound peek through them with a visible cameltoe-crack. I wanked furiously and came again and continued wanking, but i had to keep it quiet and slow down as i heard someone in the hall. Suddenly i hear my sister outside the door saying dinner is ready. It was so hot standing there with her dirty thong pressed against my nose smelling her pussy and slowly wanking with her just outside, i came again extremely hard just after i answered her. That was one of the most intense orgasms i can remember. I heard her go upstairs and came even two more times, my balls were empty the last few times though. I was completely drained both of cum and energy. It was the best Christmas present my little sister ever could have given me, and she didn't even know about it! I really debated what to do with the thong afterwards, but i thought she probably didn't have taken many with her back home for her stay and that she would notice them missing, so i very unwillingly realized i had to put them back :( I never got around to use them again before i saw them hanging to dry on the clothes line... Today she was out and the door to her room was open. She often leaves her dirty clothes there, and bingo, a pair of red panties on the floor! Just normal bikini-style ones and not a thong though. I picked them up and had a quick smell, but unfortunately they didn't smell much. I just hope i get a chance to find a few pairs of her really dirty and wet thongs again before she goes back to college! Hopefully some she has masturbated in that is a little less dirty and more delicate so i can lick them clean!
