you over hear a friend talking

You over hear your friend talking to your other friend about a her sister was so cool, and how she streaked across campus. Who ever did that would be so cool. You walk up to her and tell her "Why don't you do it then"
"No way I would be to embarssed to do some thing like that" she replied
"Soon you dont think you have the body for it huh?" You in a teasing voice.
"Then you do it if you got the better body" she replied a little angry.

"OK" You say.
A suprised look falls upon all you friend incluing your own. Did i just say that you think?
With no control over your body you walk to the bathroom, the rest of the girls follow. Once in the bathroom you begun to strip. Trying to stop you can't. What are you doing you friends ask as you set free your 27c breast. You dont answer. You pull you skirt down and remove your white cotten panties. A few seconds later your totaly naked. Your next words that you say are "where to?" as you hand your friend your cloths who are just staring at your naked body. One of your friends takes your clothes laughing, she says if your really into the exbihition thing trash your bra and panties, without a second thought you do so.
finlly your able to speak "Don't let me do this, i cant control my body"
Confused your friends test you on this they have you play with yourself.
Trying with all your might you can't stop your hand from reaching down to your clit, in a moment your rubbing it and felling the your cunt become very wet. your other hand starts to play with you tits, you thumb the nipple and that starts to send you in to a orgasim. your friend tell you that you can stop, but the urge to cum is to great as you press your two finger into you cunt. A deep moan brings you to your knees as you reach you climax.
