I was in gym class and we were playing a game of mixed volleyball, just watching all those girls jumping in their short shorts and their titties bouncing around made me so horny. As I was starting to get an erection I figured I would go to the changerooms and pour some cold water in my shorts, I told my gym teacher I was going to the bathroom and she gave me the key to the changerooms.
I was walking to the changrooms when I noticed I had the key for the girls changeroom as well, I was still really horny at this time, so I decided to go into the girls changeroom and sniff there panty's while they were none the wiser, I snuck into the girls changeroom and started to sniff all the girls panties, I was wiping them all over my face as I was taking them out of the girls backpacks, these are the panties they had worn before they had changed into there gym gear.
I saw a bag of a really hot girl in my class, her name is Casey, she is blonde really hot with a fantastic body, I saw her panties in her bag, I took them out and smelt them and rubbed them with all the sweet pussy juices in them all over my face.
I was so horny and since I was alone I figured I would wank off, I got tottaly naked and wrapped her panties around my cock, I came all in the panties and figured I would leave her more of a surprise, I wanked a nice load into her water bottle.
I then quickly went back to volleyball. After the game I watched courtney come out of the changerooms, she was wearing a skirt and could see her wearing the panties, she was squeezing her legs together in discomfort and I saw her hand go up her skirt and wipe her panties, I could see the wet cum stain in her panties as she lifted the up for a quick glimpse, I almost came again when I saw that, then I saw her get out her drink bottle and have nice big gulp, I could see her gulping and drrinking my cum down her throat.
I often masturbate over casy and hope to get her panties again soon!
