I sat in the Slytherin girls' dormitory, my Potions textbook open in front of me, the words blurring together. I had actually withdrawn to study in peace, away from the noisy bustle of the other Slytherins, but the absolute silence of the dormitory and the hours of cramming for Potions made me sleepy and bored, but also kind of horny. Sighing, I closed the book and looked around. The room was completely empty and it didn't look like anyone else was coming in. Of course, my naughty idea was more than risky, but I had to do something quickly to fight the boredom and keep myself occupied elsewhere. I put the book aside and began to touch my body, squeezing my soft boobs and playing intensely with my nipples. The feeling of my nipples tugging made me instantly wet, I realized as I slipped my hand under my panties. I slowly took them off and ran my tongue over the wet spot to taste my pussy. This excited me so much that I started fingering myself to lick more of the juice from my fingers. My lust was now incredibly high and I could no longer think rationally. I pulled two toys off the shelf, which I had put a spell on so that only I could see them, and started to play with them. With the smaller toy, I first had to stretch a little to prepare my pussy for the monster it was going to have to deal with. I immediately noticed how greedy my pussy became and swallowed more and more of the toy and finally switched to the larger one, which was quite a challenge. I carefully pushed the tip of the large dildo inside me and let it slide slowly into my pussy. To enjoy the whole thing even more intensely, I turned around, bent over, let my ass slide up and down, and enjoyed the feeling of being fucked to orgasm...
