Dominic Pacifico is one of those rare models that seems to be finely tuned with his butthole. He is quite aware of the mind/body connection with the sensations in that hot rectum. It's a treat to watch him work his hole over, first with toys he can handle himself, then with the automated fucking machines from Butt Machine Boys. As far as I know, these machines are created by the people at Kink.com, designed exclusively for use in scenes like this one.
It's truly astonishing the variety of machines they have and the amount of scenes they have with hot guys like Dominic, all spreading their hot little asses to be plowed by huge dildos attached to pistons with various speeds. Designed for hole abuse, Dominic looks like he's really enjoying getting his mancunt wrecked. I only wish I could have been the lucky son of a bitch who filmed him training his hole as if he were preparing for a gang bang.
You can see Dominic's luscious hole getting used by visiting ButtMachineBoys.com. And if any of you techny, horny fuckers contrive one of these on your own, I want you to send me pics or invite me to use it on you!
If you wanna try working your hole (or a slave's hole) with a fuck machine, there are a bunch of types of fucking machines at eXtreme Restraints (a straight sex toy site).
