We see a schoolgirl who is trapped inside a large PVC bag with the air removed, but with an air supply coming from a breathing pipe attached to a PVC bag, which is securely fastened around her neck. She receives an Hitachi on her pussy to cum four times, while I block her only way to breath. At one point, the breathing connector ends up under her chin, and she is unable to get air, so I must intervene to avoid a bad situation. She panics twice during this time.
