Collaborative sex stories let us write the plot together
(Her Secret Fantasy, continued by Emma...)
“I want us to have sex with your step-sister Amy!” blurts Rachel.
You are shocked to hear your girlfriend suggest something like that. You have always been very close to your step-sister, and it’s true that the two of you had fooled around a bit when you were younger. But you had always thought it was a well kept secret.
“What are you talking about!” You sit up in bed, as if accused.
“Don’t be silly, Amy was a good friend of mine, long before you and I got together. She told me everything about your adventures when you guys were at the university.”
“What! Wait, no What did she tell you?”
“Well, only that you used to fool around a bit when you were drunk, no details really. It always turned me on to think about the two of you together, and it’s been a secret fantasy of mine ever since.”
