Me and a friend of mine shoot back and forth with new ideas, mainly involving Pathfinder.
Games I run for him:
An ancient wizard realizes her power is beginning to wane due to more than a millennium of inactivity. Advised by the djinni she has bound to a skull, she leaves her demiplane to seek seven children, each with a disposition rooted in one of the seven sins, to train as apprentices so she can passively gather their residual power. The character is a massive shotacon, however, and also enjoys using Alter Self to bang other women. Since the game's start, they've also decided they want to gather some reliable compatriots for the Trial of the Starstone.
In a time when humanity was in its infancy, a blue dragon is born. At an early age, exploring his mother's territory outside of the cave, he encounters a drunk band of human travelers, agreeing to help them if they will sate his curiosity of their race. They teach him about many things, but he notices one is more lithe and curvaceous than the others. She teaches him the difference between men and women, leading to a very early sexual awakening for a Very Young Blue Dragon. He now has ambitions to acquire more "wives" for his harem, and has since added a female jackalwere.
There are more, of course.
