Funnily enough, my first roleplay isn't sexual at all. It's actually closer to being wholesome.
A sorceress girl born into a small village is profiteered by her family for her abilities. She enchants trinkets, performs spells and incantations, brews potions, and tells fortunes all for the sake of making her father smile. However, she knows she is being used and becomes quite jaded with the whole affair.
One day, as she plans to run away she comes across a young boy. The boy is an inventor, who shows off his latest invention. It's a messy little black box that occasionally opens and the sound of a bird chirping plays, utterly worthless, and yet he's so delightfully proud of it that she ends up keeping it. The two befriend one another and when she learns that the boy comes from a troubled home as well, they agree to run away together.
Years later, the boy is a travelling merchant selling his wares. The sorceress follows him as a companion as the two try to sell his inventions to villages they pass by as they travel the world. As they traverse continents, they encounter new civilizations and new cultures. Their friendship strengthens with every new adventure...
