Collaborative sex stories let us write the plot together

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

“Well… I want to find another couple to partner swap with,” your girlfriend reveals.

“What? Really?” you reply, surprised to say the least.

“Yeah… Is that bad?” Rachel asks sheepishly.

“No… not at all. I’ve always wanted to do something like that,” you admit, hoping this isn’t a trap.

“Cool, because I know the perfect couple,” she says with a smile on her face. “My good friend Monica and her new boyfriend. He’s super hot, and I’ve seen how you look at her too,” she says. “What do you think?”

“Call them up!” you say to her, trying to hold back a smile. She’s right, you’ve always dreamed of fucking Monica.

“Okay, I’ll set something up for this weekend” she says, reaching over and grabbing your cock through your underwear. “I can’t wait for us to watch each other,” she whispers as she strokes you.
