A reoccurring dream needed me to actually discover the word to describe it. That word is irrumatio.
The dream starts with me asking a man (usually an ex) to fuck my face. The man then asks me to describe why I want to, I have to use the right words to 'persuade' him to fuck my face, I put my hands to my now really wet pussy, I say that it would really turn me on,even the thought of it is making me more than moist. I then beg for him to fuck my face, I beg again and again and again. He succumbs to my wishes and somehow I am still able to shout 'fuck my face' while he is fucking my face.
I have been using this dream as masturbation fodder for the last couple of days with extreme success.
