Mary and Susan - the notorious Tests sisters - live for inventing wild contraptions. But what they really crave, they love to try out their creations… and trust us, it’s anything but ordinary.

Their latest creation? A sleek robot covered with mechanical tentacles. Built to simplify routine tasks, this invention is supposed to be a game-changer in their daily routine. But the twins have their own special plans for it…

What you might not know is that these two have an insatiable appetite for pleasure, and being fucked in every hole by a spider-like robot is apparently part of their “routine”.

Imagine the two of them entwined around this alien-like machine, their skin flushed and every nerve ending ignited as the robot's arms explore each secret spot. The sensation of cold metal mixed with heated passion sends waves of pleasure cascading through them.

Every thrust, every stroke, every teasing touch is expertly calibrated, turning their home workshop into an erotic playground. Their laughter mixes with gasps as they lose themselves in this intricate dance of man and machine.

This isn’t your average invention, it’s about the raw, unfiltered lust that the tests twins exude. These ladies push limits and test pleasures, and you’re invited to watch, join, and maybe even take control.

Dive into the sinful world of Mary and Susan, where every mechanical limb can fulfill your darkest desires. Are you ready to experience a pleasure unlike any other? The twins await your command - and the robotic arms are itching to explore.

Step inside this twisted, tantalizing playground and let the machine do the rest. Are you bold enough to push the limits of this mechanical delight? Only one way to find out...
