OK, so "potatoes" asked me, "what would really turn you on? do you have any preferences as to how you would like to be treated? ae there any limits that you have?"  (Thanks potatoes)

There are many answers to this! Here is one.

You can see on my profile that I like blindfolds. It is a real turn on to not be able to see what is going on or being done to you or about to be done to you.  In one of my fantasies my husband gets a few of his friends together for a game of "guess who"?  He undresses me completely, ties my hands behind my back and makes me kneel down, with them all standing around me.  Then he puts the blindfold on me and tells me to open my mouth.  One by one they each take a hold of my head and place just the headof their cock into my mouth.  I have to guess which one was my husband's. Whichever one I choose then puts his cock in my mouth again, but this time fuck my mouth until he drops his load there, and I swallow it.
