This is how the fantasy goes

What I hadn’t realized was that as I was making love to you, you had left the door unlock, and a young female friend of yours had walked into the room. I could not hear her enter the room because your thighs were wrapped around my ears so tight. As she entered the room, she slowly, carefully and quietly locked the door behind herself and proceeded to take a long, hot shower. Very quietly, she dressed in a see-through negligee and exited the bathroom taking in the view as you performed your magic on my face. As you reached backwards to hold my manhood and stroke him, you slowly slid off of my face, down my chest, across my stomach and started to rub my shaft between your legs. Once you first began to slide off of my face, your friend knew that was the signal for her to come over to the bed and join us. She slowly and quietly walks up to the edge of the bed, smiles at you, looks down at me with my closed eyes because I am in sheer ecstasy and slowly straddles my face, putting her pussy over my mouth just as you had done. Her face, now looking down at me, has a big, broad smile which has emerged from her lips. My eyes open in shock as I was not expecting anyone else to be in the room with us. You calmly and seductively in a cat-like voice purr those words into my left ear, “This is going to be a night to be well remembered for everyone involved in this room.”
