In the living room of Alexandra’s mansion, there’s a vacuum bed made of reinforced black latex. It is suspended from the high up ceiling and can be automatically lowered down to the floor. Between and within the heavy latex sheets of the vacuum bed, there’s a cable to connect to Alexandra’s maintenance port, allowing for full maintenance sessions, while still being completely trapped within.
The bed can be lowered down by Lumina, so Alexandra can enter and connect the cable to the maintenance port. Once everything is ready, the opening in the bed closes and the air is pumped out, vacuum packing Alexandra’s encased form in between the thick layers. Finally, the entire structure is lifted into the air again, suspending it 3 metres in the air, with Alexandra helplessly being trapped within it, as long as Lumina wishes. The latex the bed is made out of is strong enough to easily carry Alexandra’s body, without the slightest risk of it ripping and Alexandra falling out of it.
The rectangular, heavy black latex that makes up the entire vacbed only has one opening at the side. Once Alexandra is fully inside, that open side is closed off and actually glued shut with a special chemical solution, ensuring that absolutely no air can escape or enter. Only another solvent solution, controlled by the automated systems by Lumina, can open that side again for Alexandra to be freed.
Lumina often uses Alexandra encased in the vacuum bed as her own bed, her projection lying on top of the immobilized and encased Alexandra, playing with Alexandra’s extreme contours of her slave.
