ONIN-092 First time with a machine, I was hesitant at first, but then I was hit by the machine’s precise rhythm and got completely overwhelmed!

Eight curious women take on a masturbation device called the Fuck Machine. A large dildo is attached to the end of a heavy mechanical apparatus, and when the switch is turned on, it becomes a piston-like robot that repeats the same motion with precision. After preparing themselves with plenty of lotion, the girls cautiously insert the cyborg device into themselves. Starting with slow movements, they gradually become more and more stimulated, increasing the machine’s speed until they reach climax.
