Contaimante the population with a Futanari disease

A futanari disease? No such thing; being a futa is a positive trait. What you're looking for is an extract. An extract that is infectious, because you can't be assed to go around and ****-vaccinate the entire population, no.

Instead you quit your job and use your savings to fashion yourself a tailor-made costume - concealing enough to hide your identity, but leaving nothing else to the imagination. Adorned in tight spandex, you wage a wave of terror onto the city. Law is helpless in the face of the shameless show-it-all - The Prick.

Using your powers, you steamroll every bank and safe deposit within a fifty mile radius, leaving behind nothing but destruction and cum oozing out from every crevice of the crime scenes. By far your favourite method of opening vaults is to jam your raging erection against a steel door, and then blast a clean hole into it with a simple ejaculation. You've also acquired a perverse fascination with law enforcement bullets harmlessly richocheting off your tight, steelhard body.

Now you have enough money to buy off half the country.
