Shortly before their orgasm together, Minnie's old Soviet Army air tank was completely empty. The problem was that we were only able to fill the bottle halfway at up to 75 bar because of its age of over 60 years. 75 bar in a total of 6 liters won't last long if you're fucked hard under water. While Eduard continued to fuck her from behind, Minnie was suddenly completely out of breath. We were only able to finish the scene because our cameraman spontaneously shared his air with Minnie and later she could breath from our small emergency bottle.
