Went to private religious school my entire life. I was a virgin who had never kissed a girl or seen anyone naked in real life. Finally, parents ran out of money and sent me to public. My first day, in the 9th grade, my first class, four guys at my table put jackets over a girl as cover and finger banged her pussy and ass until she came multiple times. The teacher was incredibly old and had poor hearing, and unless she was just too freaked out to say anything, never noticed. At one point the girl even raised her hand and asked the teacher to come over. The teacher stood their and answered her question, and at one point the girl put her head down and sighed hard and long (assuming an orgasm), then said thank you while looking right in her eyes. The girl ended the class flashing everyone her tits.
