Slow Death

You could just be sitting down talking to your shrunken captive and have him standing on your belly. You could be telling him that hes standing on his tomb right now, tell him that being in your belly is a very slow. Hell be alive for years leisurely digesting inwards you, being a witch you can hear his sobs for grace. Hearing him scream and cry makes you happy. Then again after you eat him spend a couple of minutes laughing at him and rubbing your belly, saying you can feel him trying to get out and hear his screams for mercy. Say youll enjoy having him as your prisoner, slowly digesting in your belly for years to come.
