Well, mine was not considered sex in school, coz that time was our first time...
What did I mean? Well, thanks to our pitiful sex education, I didn't know the location of her vagina...

To make a long story short, we went to the male toilet to do it. We cooped ourselves up in a cubicle and I undressed her till she was nude. That was the first time I saw her totally nude, shiok man! Hahaha.
Anyway, I pulled down my pants and tried to enter her. The hilarious part was that both of us were standing up, and her legs were closed!! So my penis only touched pubic hair!!
Hahahaha
So funny....
But it became anti-climatic after a group of students walked in. We had to stay there very quietly, and waited for them to leave. They took so long.

By the time they left, no more feeling liao, so she dressed up and we left...
