You hurry toward the costume shop, you can see it now. The only problem is, you can feel your mind slipping. Your cock is in charge now. Your... Massive... Long... Thick... Throbbing.... COCK.
The throng of people around you has grown to almost a hundred. Your cock is starving and, not able to resist, you slam it down onto 4 people, absorbing them immediately. In response, your shaft lengthens and thickens, ramming into 2 more people and absorbing them without any effort from you.
You can feel yourself changing. Limbs swelling abnormally long, about elongating, cock stretching and swelling beyond reason. Your limbs are moving to fill the needs of your cock, you have no control now. Your arms begin swinging wildly, grabbing people left and right, and then thrusting them down into your cock, which begins to progress down the street, it's colossal head moving further and further from you as its length skyrockets.
"PLEASURE ME, MORTALS" you hear a growling voice say. You realize that it came from you. Figuring they have no choice, people rush forward and begin rubbing the shaft of your titanic cock. Doing this causes them to be absorbed within seconds, making your cock grow and swell endlessly. Laughing, you tear up a nearby building with each hand, using very little effort. You begin to rub the two skyscrapers along the length of your kangaroo penis as your point of view raises higher and higher.
Soon your cock is nearly half a mile long, and you are almost 1000 feet tall.
Rubbing faster and faster, growing faster and faster, now that you passively are absorbing people as your size increases.
You suddenly climax, sending your seed in every direction for miles, coating the landscape, still growing.
