King, a Great Dane, got very dirty outside so I give him a bath. To my surprise, his doggy cock is fully erect during bath time, which excites me. I wonder what it would feel like to be knotted by him. I reach back for my vibrator so I can please myself while I stroke his cock. He gets excited too and jumps on my back, pushes his penis into me and takes me. He humps me but I decided to take matters into my own hand and cum from this beastly animal. I vibrate myself to orgasm while he’s inside me and dumps his warm cum inside me.
