I get turned on by the tought of having a invisible naked woman next to me so....
I wished that Amanda would follow me into the back room and have sex with me, and that nobody would go in the room while I was in there.
I then start to walk out into the back room and I could hear Amanda's feet so I knew she was following.
I then sat down and and she then lied on top of me, I could feel her body rubbing against mine.
Her legs, her face, her lovely breasts!
Then we did it, we had sex!
