Here's a dare for you:

You'll go for a ride in your car.

Preparation: You need a bike lock which you can lock without the key. So it should be open and the key stays at home. Take it with you.

During car ride:

When you meet the first red traffic light, take off your bra and put it on the dashboard, so everyone can see it there.

At the next red traffic light finger yourself until it gets green.

The next one - finger yourself and moan loud - at least one of the windows have to be a little bit open.

Next red traffic light - close your eyes, finger yourself and moan loud. Right you won't see when the traffic light gets to green: Just go on till someone honks or you have an orgasm.

Now drive somewhere, leave the car, take of your underwear, your top and your skirt or jeans (whatever you wear) and use the bike lock to lock your clothes to a tree. Right you have to make your way back home naked - well ok, in your bra waiting for you in your car.

So have fun!
