I go down to the Hufflepuff common room to study. After a little bit of reading, I get so horny! I look around to make sure no one is around before I pull out my magic vibrator. I loosen my tie and pull up my bodysuit to feel my DD breasts. Looking around to make sure no one catches me, I play with myself and it feels so good! I have an amazing orgasm, covering my mouth so I don't make too much noise! I quickly get dressed and get back to studying...
