Clothes pins on your nips. Then squeese them on. Get on your knees, legs spread, chest on the floor, and ass in the air. Now do as CADENCE said. Ice cubes in your ass, but give them time to melt, staying in this position. When the cubes are melting, add a few more. STAY IN POSITION. Then went the time cums, undo you self, but make it count. Hold out LONGER than possible.
The longer you hang on, the closer YOU cum to fulfilling you desire.

BE SMART, CAREFUL. S G
