Next exercise, this will make you cock bigger over time. You need this one quite badly!
Grab the base of your cock and slide your hand upwards.
Once at the head, squeeze tighter but keep moving your hand upwards so that you stretch that cock. Feel the pull and let your hand slide off the end. Do it again with your other hand.
Give me 100 of those strokes, alternating hands as you go.
Finished?
You know the drill, give me another edge then...
