Once Upon a Screw

You are a traveling adventurer, in a land of fables and magic. You have interrupted your journey to rest for the night in a small roadside inn, and you have spent the evening in conversation with the inn's only other guest. She's beautiful, she's intriguing, and after losing a friendly wager with you, she must now tell you a story.

Specifically, she must tell you a story about what might happen if the two of you had sex.

She starts her story by properly introducing herself. From this point forward, all of the words are hers.
