Whilst going down on a WG, my feet were hanging over the edge of her bed. Unbeknown to either her or me, her new kitten had joined us in the room, saw my pinkies and thought that they'd be good to play with. It jumped up and was hanging from my foot with its claws dug in. I jumped a mile, from both shock and pain, the cat flew off screeching the prossie thought I had killed it. On closer inspection my foot had several large scratches with blood seeping from them.
I had to go and have a tetanus jab as the kitten had not yet had all it's jabs. Luckily as a single bloke no explanation was needed to anyone other than A&E dept
