My uncle used to be an ambulance driver and he told me a pretty gruesome story one time.
It was pretty late on a Friday night and they got a call about a woman who had just had a terribly violent epileptic seizure. They arrived on the scene to find the girl had stopped but I think standard procedure was to take her in the ambulance and check if she was ok. Upon arrival at the scene however my uncle saw that her boyfriend was receiving some sort of attention from the paramedics. He peered over to see that he was sitting down with a white towel over his lap with a large circle of blood on it.
He asked one of the paramedics what had happened and he was told that the girl was giving him head and mid bj she had a very violent seizure. His penis had been lacerated to absolute ****
Just take a moment and really imagine that happening to you...
