Really can't Whistle with a Cock in my sissy gurl mouth, but I Love to Hum on it a lot when I am sucking cock! Humming on a Big Cock in front of a Beautiful Woman while She'a talking dirty to me is so much Fun! He's fucking my warm dripping wet sissy gurl mouth and I'm gagging and humming along as He's Verbally Humilating me as well! Yummy Fun!
