Big boobs hurt man

I was standing next to a desk, writing my name and student Id on my assignment that I was bout to submit. When I was done I quickly turned around to rush towards the teachers desk but I didn't know my friend was standing right behind me. I collided with her chest and fell right in front of two males and my ex bsf and her friends. I am so embarrassed. My ass hurts now. I am on my periods too man.
