I guess I was curious, maybe even a little adventurous, but this turned out to be such a turn on.
It happened in school. During gym class which I totally hated. I had managed to bunk off the lesson by telling our coach I had my period. (I didn't but hey she believed me!) So that left me in the changing room alone. I had mooched around a bit and lost track of time. Of course, I was horny, and seeing the other girls change hadn't altered that. Some were naturally developed, but others had shaved 'down there', and I had too, only the previous evening. So I decided I would rub one out while I was alone in there. I even decided I would have the big O with a lesbian fantasy, so I wandered around until I found Rose's panties.
Rose is a bit of a teacher's pet, and a geek, but she has a totally sexy body and face. I decided I would smell her panties. When I picked them up, they were actually WET! Rose!!! Of ALL people! I was standing there, hand in my own panties and smelling Rose when I had the dirty idea to put her panties on. I slipped mine off and put hers on. It was so horny having her wetness against my smooth pussy. I knew I was creaming into her panties, but I really didn't give a shit. Then, OMG I heard the class returning. I didn't have time to take Rose's panties off, or put mine back so I stuffed mine in my pocket and dived for the toilets.
I heard the girls getting changed and knew little Rose would not make a fuss because she couldn't find her panties.
Well the rest of the afternoon, I found myself sitting in another girl's wet panties! It was a total rush! From time to time, I could even smell her scent. By the time the end of the school day came, I really couldn't wait any longer. I had to go jill off on the way home. So I went into some farmland that backs onto my house and into a field. There I just stood in the corn and lifted my skirt and jilled a good one out into Rose's panties.
That night, I licked them as I jilled off again.
