Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Liasa...)

“It is your fantasy, my love. You should choose who you want and how to get her.” You are not entirely sure that Rachel is truly serious and leaving it in her hands may be the best way to leave the uncomfortable situation.

“What if I get someone not to your taste?” she asks with a wide grin.

“I think we are together long enough for you to know what kind of women I like,” you answer with a smile.

“Sure I do!” She punches your shoulder lightly and giggles. “Don’t think I fail to notice when you ogle other females.”

“It’s not the best time to get jealous,” you laugh. “So. It’s decided. You will find a slave for both of us, right?”

“Sure. I promise you’ll like my choice,” your girlfriend says, before kissing you on the lips. This starts another half-an-hour-long sex session.

A few days pass and you completely forget about Rachel’s fantasy. After all, she never mentioned it again. You come back from work, tired after a busy Friday, to be greeted by a smiling Rachel. “Honey, I have a wonderful present for you in our basement.”

She leads you downstairs, opens the door and your jaw drops as you see a naked female with a piece of duct tape over her lips and another binding her wrists together.

Who is this woman?
