Metal Bondage – MB660 – Liz versus the Blowjob Machine

I only tried the Blowjob Machine once before, and it needed some more tweaking. Good thing there’s always Liz Rainbow, who doesn’t mind being my test subject, even it is means she has to deepthroat all afternoon. We experimented with different heights and angles. Liz tried fighting the machine but it was always stronger. Trying to pull back against the machine turned out to be quite unwise because the machine pulls back faster on the next stroke. Liz drooled all over the place of course, and she had a lot of fun! When I unlocked her hands to let her out, she decided she wanted another go and tried to reach the controls herself to get deepthroated some more!!
