Collaborative sex stories let us write the plot together

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

Rachel bends you over an armchair, your ass in the air, and handcuffs your legs and arms to it. You feel insanely exposed. She leaves, and comes back in a minute with a dog shocker, a whip, and the biggest vibrator you have ever seen.

“You have been a bad boy, Ross, and deserve to be punished!” she proclaims. You are insanely worried about what will happen next.

Your girlfriend then shoves the vibrator into your tight, virgin ass, only getting the tip in. At this she gets frustrated, and takes her foot and kicks it in, until all ten inches of it is in, and she turns it all the way up.

She takes the shock collar, and puts it around your balls. She proceeds to take the pantyhose out of your mouth and hand you the remote to the shocker. She tells you to hit the button, and hold it, while counting her strokes of the whip. You start crying at what has happened.
