On a January morning I woke up at 8 am and panicked since I was already late to school. My sisters and parents all went to my grandparents’ house for the break (ugh my school didn’t have it at the same time) so I was alone. I jumped up and took the fastest shower in the world. less than a minute probably. I got out and I couldn’t find any clean panties so I had to choose going commando or wearing the vibrating panties my ex gave me for christmas (one of the reasons hes now my ex). I didn’t think it had any battery left so I just chose that one. I get to school for my second period and its physics. I sit down but i think a loose strand in my ripped jeans switched the vibrator on. I had no idea how to stop it so I was about to stand up do get the hall pass but my legs were weak. My teacher started to notice the noise and she asked the class to turn off our phones. Obviously the noise continued and it was even more embarrassing cuz then people would know who it was if I left the class. I said I needed to puke and sprinted out of the class with the strength I had left. I needed to get to the bathroom cuz I was getting close so I crawled to the bathroom around 20 ft away. I got in and it was empty, thank god. It felt so good I decided to finish. My dick was throbbing and I let out the biggest load of cum on the bathroom floor, it looked like someone exploded an expired gallon of milk. I broke off the switch on my panties and went back to the class. When I got home I burned that shit in my garbage can.
