Your shoulders being held in place by the lion's weight, you are unable to reach the dagger. Groaning in despair, you can only struggle as the lion examines you. It decides that you're fit to eat, and engulfs your head in its maw. It swallows you down, stopping briefly to curiously lap at your penis, which is steadily growing (you can't help it!) before the only thing outside the lion is your legs. It slurps them down, and sends you to its stomach to digest.
