ONIN-092 First time with a fuck machine. At first, I was scared, but the precise machine pistons made me cum like crazy!

Eight women with insatiable curiosity take on the dildo machine "Fuck Machine." The ominous mechanical device has a giant dildo attached to its tip, and when the switch is turned ON, it repeats precise piston movements! The girls apply plenty of lube to their private parts and prepare themselves before cautiously inserting the cyborg cock into their pussies. Starting with slow movements, they gradually feel better and better, increasing the machine's speed until they reach orgasm.
