Collaborative sex stories let us write the plot together

(Her Secret Fantasy, continued by Cream of Peen...)

You continue jerking off with the strap-on still wedged into your rectum. When you finish you blow a bigger load than you ever have, jacking it with a seven inch sex toy up your asshole. Then you turn back to your girlfriend and give her a passionate thankyou kiss on the mouth.

After you break the kiss you look down to see the foreign object that moments before was railing you from behind. What you see is clearly reminiscent of a seven-inch strap-on, only the straps seem to be missing. You can do nothing but sit on the edge of your bed in stunned silence for a few minutes, wondering how you could’ve overlooked this.

“What’s wrong, babe?” Rachel asks.

Still stunned, you ask tentatively, “Is… is that a dick?”

“Well…” she replies, “it’s not NOT a dick.”

“You’ve had a dick this whole time!?” you yell.

“Oh come on,” she says, “you know you enjoyed it. Besides think of the possibilities…”

Your dick suddenly hardens back to full attention as the options swim through your mind.
