Getting caught

Okay so me and my boyfriend go to the same school and even tho he is a grade above me we have the same bio class so I asked to go to the bathroom and once I got there I texted him to come to the bathroom where I was so when he showed up we started making out and fooling around I was giving him a BJ and a girl walked in the bathroom when he was cumming and he moaned really loud and all you heard was her stop in her steps and freezehe walked out all cocky and proud but I walked out like a dog with there tail tucked she looked at me and winked (shes my best friend lol she had bio with us too and came to look for me lol) have you ever been caught and where???
