With the unit's transformation so effortless, you realize something. See, you secretly had a thing for vore, imagining yourself being swallowed whole and getting trapped in the gooey guts of some massive beast. It was always an unrealistic fantasy though, and you knew better than to talk about it publicly. But now that the "public" was gone, and you had near unlimited power over the world, you could indulge in all of your strange fantasies.
Looking at the centauress, you give her your next command. "Centaur, you are feeling extremely starved. Normal food just doesn't do it for you, as your gargantuan stomach digests it all instantly. The only way you can satiate your hunger is by consuming a puny human, who will digest inside you for several hours before becoming some fat on your body. You won't eat a human by force, however. Instead, you will have to convince m- the human to let themselves become your meal. Your body will stretch to fit the whole human."
As you finish speaking, you notice a change in the centauress. She is visibly in distress, and her horse stomach is loudly growling. Her body also seems to be moving a lot more in the areas around her mouth, throat, and anus, like they've been made more rubbery. But what strikes you the most is that the look in her eyes has gone from mindless indifference to stress, concentration and a deep, voracious hunger. And those eyes are staring right into your soul.
