In this first bubbler bottle video clip karina is tied down to the bed while dressed in latex corset, panties, stockings, gloves and a modified rubber s10 gas mask. the gas mask is connected to the bubbler bottler via a long section of tubing. A small white plug by the gas mask can be opened or closed to affect breathing through the entire tubing. the bubbler bottle has a thin rubber tube that is inserted into the side of the bubbler bottle, reducing the air flow, particularly when it is inserted into the liquid (water) within the bottle. The further down the tube is pushed, the harder it is for karina to breathe. watch as she undergoes her first experiment in breathing using a bubbler bottle. In the next video clip she will be breathing air through a much more intimate liquid. ;)
