Allie James is locked into a automatic blow job machine, with huge ring gag

We turn the machine on low to start and the machine moves her head back and forth on the hard cock. The vibrator on her clit is starting to make her cum, and we press forward. Allie is completely helpless as the machine is in control of her head. It pushes her head back and forth on the cock over and over, never getting tired, never stopping. Her mouth is held open by the huge ring gag and the machine uses her throat just like it would a pussy.
