I’m in my Stepsister’s room wearing my school uniform looking for my gold necklace, as I’m going through her desk I find something surprising, her vibrating wand. I’m telling my friend all about it on the phone, but decide that I want to use it because I’ve never tried one before. I sneak into my bedroom and sit on my bed. I’m nervous in case my Stepsister comes home and finds me using her toy, but I can’t resist the temptation to try it out. I place the end of the wand on my clit through my white cotton panties and can’t believe how good it feels. It feels so good that it isn’t long before a wet patch becomes visible on my panties. I find the best spot where it gives me the most pleasure and slowly rub it up and down on my clit. I end up having the most mind blowing and intense orgasm of my young life, as I cum hard. I put my fingers in my panties, and I’m amazed at how wet I’ve become, nothing has ever made me this wet before. I decide to try for a second orgasm, but get interrupted by the sound of my Stepsister arriving home, and have to quickly get away before she catches me using her toy.
