Schoolgirl has to masturbate while reading in front of the whole class

today’s lesson was a little different. We all had to read the tasks aloud, but when it was my turn, the teacher took a device to make the presentation more difficult. I am sitting on the device and I started to read, but suddenly began to vibrate. I felt strong vibrations in my vagina and it was really difficult for me to speak without moaning. I could not breathe, my body was sweaty, I continued until I could not longer resist and I had an orgasm in front of the class. And then, when all the students are gone, and I remained alone with the teacher in order to continue to have fun but with a real cock.
