Just imagine that you have the super power of take parts of your body out of you, clean it up, and then assemble it again? This is an idea that growed in my mind since long time ago. A lot of holes, so complicated phisiology, and to put the berry on the top of the icecream, the intimate zone of a woman is inside her!!
That was my first concern, the clean process. Maybe you are thinking in this right moment, that the human body is so intelligent that it cleans itself, bla bla bla, but just think when you have an infection? or a desease?
But ok ok, just leave that part apart, lets think about the ear!, that is an organ that the human has no matter sex, it is a high probability that one day you had a clogged ear with water, what a wonderful super power to take that ear off, turn upside down, dry the annoying drop of water, and put it again in it place! fiuuuuuu! nice ah?
But, the eternal buts, the things that a human can do to another human, the most wild lion is a baby compared to it. All the horrible ideas you can imagine, think about stoling someone parts for fun or evil, or sadism. A point that blow all the sparkling bubbles this idea could generate. But just to leave a nice picture, regardless of human nature, that idea would be amazing!
