Lana is placed inside the twin chamber inflatable sleepsack. The zipper is closed leaving only her pussy on show through the crotch hole. The pump is turned on and soon the sack is fully inflated, I then encase the sack with heavy black shrink wrap making sure the sack is airtight a breathing tube is then placed through the mouth hole creating a perfect seal. A plastic bag is then placed onto the end of the breathing tube.
