Find a public Glory Hole to do this dare. Your bandage will be a hogtie on your knees propped up against the wall. Use at least one lock in your bondage with a chain or cuff. Attach the key to the lock on a string long enough to fit over the length of a erected cock. Draft a note saying-

"I need to give you a blowjob for my freedom! Attach the string around the base of your cock, put it through the hole and I will suck it off your penis. Once the string has gotten over your cock head, do not release your cock and let the key through until you have released a full load of cum into my mouth. This is the only way that I will except the key. If I can't get it over your cock head before you release your your load, pull the key back and put it where you found it for the next person; same goes for if it falls. Enjoy!!!"

Place the note and key on the other side of the Glory Hole. On your side, put yourself in the bondage and wait for your Cock.

So from your perspective, you will be forced to suck and lick the cock until the string is over the head. The hardest part will be the base where you will need to deep throat and try to hook the string with your tongue. If the cock is the right size for the hole, this will put tension on the string while you try to suck it through. Once you get the string over the head, the key will not pass through the cock and you will need to wait for your mouthful of cum. Make sure you have a good grasp of your key to freedom with your tongue or you'll have to do it again. Once you have gotten the key through the whole, you'll need to put the key in your mouth twist your head around to where your wrists are and split the key in the general direction. This will force you to swallow all the hot cum so you don't make a disgusting mess all over your clothes to go home to. Fumble around in your position and unlock yourself. Taste the freedom (and the aftertaste of cock and cum )
