You are disappointing me. Can't you remain fucking hard so that I can see that white fluid flow from your cock? Your chance of edging is next to zero now.
Un-tie your balls. Apply some lube on your dick.
This might be your only chance to edge and maybe cum. So I want your full attention.
Start by making circles on your dick head for 30 seconds.
Massage your balls for another 30 seconds.
Start touching your cock but no stroking.
