It had been 17 long years since Drake found the lamp. During that time, Drake had enough experiences to fill several lifetimes. It didn't take long for Drake's wishes to become completely sexual in nature. Having the ability to make all of his sexual desires a reality, his wishes quickly became kinky, depraved, deviant and intensly erotic. He also rapidly dragged many people (usually without their consent) into his new found sex life.
Even though 17 years doesn't sound long, it was long enough for Drake to become bored with his existence. He was an immortal with the ability to make all his desires come true, which can become dull rather quickly.
It wasn't long after the boredom set in that Drake decided to do something about it. He wished to have his intelligence increased to the maximum of human capacity so that he could find new, inventive ways of solving his boredom problem.
His first thought was to simply wish that he was never bored, even with the most mundane of tasks. If he wanted, he could wish to sit in a cave somewhere where he would never be disturbed and his mind would be filled with ecstacy for all time. He could simply wish to become an ethereal being made of nothing but pure ecstacy.
Those options felt a bit severe to Drake, and also a bit scary. He wasn't quite ready to shed the physical realm. As well, he realized that humans were fundamentally talented at creativity. Despite his newfound intelligence he realized that he could never naturally become as creative (and depraved) as 7 billion humans combined. And Drake was scared of raising his intelligence to supernatural levels. What if he suddenly became some Eldritch horror that decided the only way to fulfill his sexual desires was to travel the cosmos literally fucking planets to destruction?
Maybe some day, but for now he had a much simpler solution.
Drake wished to wander the earth, granting random humans their sexual desires and experiencing their new lives through their eyes. There were a few requirements: the desires he granted would only affect one individual at a time, it was required that the changes would be something Drake himself would enjoy, Drake would return to his current form and state of mind after experiencing the newest, most erotic feelings of the transformation and finally, nothing to do with animals. He just didn't like that.
Once the wish was made, Drake set out into the world to find his first subject. He left his home, found his way downtown and just started to wander aimlessly.
