In this story you're not a well known astronaut, but just a rich guy living in a mansion. Which went dipping in the water of a lake one night and the radioactive barrels lying on the lake's floor made you mutate, maybe in combination with the black ooze hiding in the water.
As an anonymous you can rape as many women as you want, without the government finding out, but only if you play your cards right. Are you smart enough to not get caught?
You have a swimmer's body, 5'8" tall, black hair, green eyes, six pack, a 7inch cock, but it'll grow.

Feel free to add your own threads. I won't have much time to work on this as much as I'd like. Yes you may add a separate thread where you're a woman raping boys.
