Anal destruction using huge XXXL dildo on industrial strength fucking machine

I mounted one of my favorite dildos on my fucking machine, which is an absolute workhorse which will drive any size dildo through any willing asshole. I get stretched slowly until my asshole gives up, letting the dildo go all the way past the last ring, which is 16 inches in circumference. I then ramp up the speed and get destroyed until I give up for good. There is never enough lube!
