this was probably 14 or 15 years before when I was in class 4 ,there used to b a female teacher(I know her name but don;t want to dislose) she used to beat in the class after making the students naked.It was science subject and everybody used to read hard in fear of getting naked still there used to b guys who were made naked and got slam on their back. now i know that that was totally sex maniac teachers for having kids naked and beating them for not knowing what is solid.liquid or gas?i still remember that was the questions we were asked during that time.
