"I'm hungry!" you say out loud.
All that hard work of growing and shrinking must be catching up with you after all.
It is a deep, burning hunger within. You must feed... NOW.
You look down at the petty security officer below you that has been reduced to kneeling before your strength.
"You'll do!" you say, licking your lips wildly.
You think of your mouth growing to accomodate your meal, as a snake's jaws would stretch to swallow a mouse.
Sure enough, your joints begin to crack and pop as they recreate the effect you would like. And soon enough your bottom jaw hangs low enough to swallow the man whole. You feel like a beast or a monster, but you love the thrill of having such power.
"No! Please no!" he cries out before your jaws quickly engulf him in one lightning-fast attack.
His body moves down your throat and through your digestive system as a huge bulge that even you can see stretching through your skin. You manage to do this with ease however as you command your digestive system to grow to support the victim's size. As he moves down to your stomach you can clearly see his arm stretching the skin of your huge 8-pack.
Finally his nutrients are quickly absorbed by your ultra-efficient body, as the outline of his arm diminishes to nothing.
As a result you feel a rush of power, and all your muscles blimp out like you've just had the most intense workout of your entire life. Your veins are bloated and pronounced all over your body, as if to accomodate for thicker blood. The walls shake and crumble around your mighty body. You cannot hold back from cumming and your huge penis sprays everything in sight with your manseed.
You roar in gratification, and within half a minute your hot, powerful stream of cum slows to a dribble again and then settles.
