Go out to the pool and wait for me.
Wait for few minutes.
While you wait, watch this:
(12 minutes)
Oh! And tie the other shoelace around the balls -- get a one liter bottle -- stand up -- tie the bottle to the shoelace.
Be in the position for the whole time.
If you want to impress me, swing the bottle while you watch, with your hand on the pathetic cock.
But remember, no stroking/rubbing till I come back.
