Back so soon!
So now you will cup your balls in the hand with the lace and your thumb tucks in just behind your cock. Now take the lace and wind it once under you balls pulling that little finger tightly into position...now wind it twice round your thumb, once round your cock and then around your first finger several times to use the slack....then tie it off...you can tie it off one handed.....but before you do that....I want it much tighter than that so try again then we carry on!
