Mini cock - Mind experiment

I let you jerk off. The only problem is: you won't jerk off your own dick! You're going to take a really nice huge dildo and jerk it off as if it were your own giant cock. You'll get used to it so fast that "your" cock will feel huge in your hand! And then I will do a little game with you. I promise you: the disappointment that you have a pathetic little dick will multiply! And I have a lot to laugh about again!
