On a piece of paper, write with thick marker pen:
"Aurelie Catena sucked it", with an arrow pointing downward.
Get naked, masturbate and cum a few drop on this piece of paper, then lay on your back, place the piece of paper on your lower belly and then position your limp, dripping cock just under the arrow.
Take a picture of your crotch and paper and post it here.
P.S. If anybody else want to do this dare, please feel free to do it. I want to start a collection!
