Time for a challenge! I am going to increase your strokes and you will have to try to last til the end. For example you will be told to stroke 1 full time (up and down) then rest for 5 seconds, then 2 strokes & rest, 5 strokes & rest, 10, 20, 50... and so on. If you cum too soon you have to ruin your orgasm, if you manage to take the maximum amount of strokes without fucking up, you will be allowed a full orgasm.
