I tie my slaveboy down and start slowly stretching his urethra out with my long metal sounds until he takes one as big as my thumb! His giant cock stays hard the whole time and I get this idea to stroke his meat while its over stuffed with metal. To my surprise he shoots his load and it shoves out the sound! Every good slave boy eats his cum for his Mistress. So I scoop up that sticky load and shove it down his throat!
