It might seem impossible to get out of this situation, but the most important thing is that you stay calm and think of a creative solution. First, try to identify any weak spots in the stomach lining or joints that you can use to break away from the furry. If that doesn't work, try to move around and create some friction in order to ignite a fire that will cause the furry to release you. If none of these work, then try yelling for help, or banging on the stomach to attract the attention of others who can help get you out.
