Stella finds herself inside a dungeon, lying on a mattress with her wrists tied. She starts to get nervous when Lilli enters the room and proposes a challenge. If she can hold out for five minutes without breathing, she'll let her go. Stella thinks it's impossible and becomes even more scared, but when she realizes it's the only way she can get out of there, she decides to try. She takes several deep breaths, moving her belly well, to retain as much oxygen as possible.Lilli then covers her mouth and nose with her big hands. Stella tries to stay calm, to hold out as long as possible. She manages to do this for about two minutes. At that point, Lilli's hands continue to gag her and she begins to struggle, kicking and making muffled screams in terror.
