I have a crush on my best friend's little sister. She is 17, very cute, but does not care for me very much.
I spend a lot of time at their house and often take her panties from the laundry hamper in the shared downstairs bathroom. I have been doing this for two years. At first I would just smell them and put them back, but later would go to the bathroom and jerk off while smelling them.
Last year Claire made the school field hockey team. The uniform has her wearing some long spandex shorts under the skirt. Claire wears some special boy shorts under the shorts. I often would make a point of being there when she gets home. She always takes a shower and leaves her panties in the hamper. When she is getting dressed I go in to the bathroom and masturbate with her moist, sweaty undies on my face. This was the best.
My friend told me Claire got into a big fight with her mom because she wanted to go on birth control pills. This made me a upset as I had always thought of her as a virgin and hoped I would be her first.
Two weeks ago our high school had an end of term dance. Claire went with a guy from my class who is a bit of a geek, not in a good way. She was wearing a blue shiny dress and looked very hot with her hair down, not in a pony-tail like she regularly has it. I admit I was jealous.
Afterwards a bunch of us went back to her place to have a few beers. Claire and her date came back to the house, but arrived last. After we sat around for a while, her date left and Claire said she was going to bed.
Later, I went to the bathroom for a piss. The mirror was all fogged up and I realized Claire had had a shower before going to bed. Looking in the laundry hamper, I found a pair of baby-blue panties, with a matching bra. The panties had a big wet spot in the crotch. After I pissed, I took off my pants and sat on the toilet seat for a quick jerk-off. Hard as a rock, I put the panties to my face and inhaled the smell of sperm! The wet spot was her dates cum that had leaked out of her vagina. Claire must have had sex with him in his car, between leaving the dance and getting home.
I forgot all about jerking-off, washed my face and re-joined the party, but went home soon afterwards.
That night I masturbated several times thinking about Claire again, but don't think I will be sniffing her panties anymore.
