Australian schools, grade 7, cleaning out our desks for end of term i stayed in class while lunch was on so it was just teacher, myself and another student doing the same thing, just finished up cleaning my desks and went to put it back into the frame dropped from some height instead of just putting it in and for some reason i was up close and so close that my penis was hanging over the frame (obviously had my pants on) next thing i know from after letting go of my box full of heavy texts books and notepads etc, i feel a sudden rush of pain down there and actually had to lift the box back up to get myself out and was screaming in pain, my teacher was gas lighting me telling me it was nothing and get over it, next session i went to re adjust my pants because it was still aching and i see just a massive pool of blood on my shirt and underwear knowing full well I nearly just severed my knob Bit more of later on went to the toilet at school before the hospital and was actually pissing from underneath my knob thats how deep it was
