Pelatihan lubang kencing - disetubuhi dengan sharpie dan jari

My master wants to stretch my urethra enough to take his cock, so I've been practicing. I don't go easy on myself - my urethra should be treated like any other fuckhole. I came twice while pounding my peehole with the sharpie. I can't wait till I can feel him cum in my bladder like a good slut.
