Crossing lines

I accepted and waved him over to sit down. He was very attractive with a chiseled jaw and salt and pepper hair. He was tall and dressed like he just came from a board meeting, he introduced himself as Derrick. I shook his had and we had a drink and flirted and he did not seem to realize I was a man until we got out on the dance floor and he held me close and I let his hand wander all over my ass and it was making me a little hard knowing this man wanted to have sex with me. Although I had been fantasizing about having sex with another man I had not followed through yet but the point of no return was here and I felt this was the time to do it.
He felt the bulge beginning in my skirt and all of a sudden had this look of fear on his face.
“are you a man?”
“Not tonight. Tonight I am Ruby”
“you are a freak”
“if you say so but I would still suck your cock in the bathroom...... if you wanted” I walked him back to the table and we ordered another drink round. He sat quietly for a few minutes and finished his martini and leaned in and told me he was going to the washroom and if I wanted to earn a hundred dollars to follow him into the stall and get on my knees. Unbelievable he thought I was a hooker! It really turned me on thinking he thought I was a prostitute. I licked my red lips and followed at a discreet distance. He checked and there was no one in the first stall so I quickly went in and he followed locking the door and I began unzipping his pants. He stopped me at first and told me not to speak. He found me very sexy but did not want to think about the fact I was a man and all he wanted was a quick hummer and he was going to get a cab home to his fiance. I just shrugged and told him to show me the money. If I was going to do this for money I wanted to see the money first. He reached into his inner pocket as I took his cock out (all four inches of it) and began jerking him slowly. He fumbled at first but produced five twenty dollar bills. I had him stuff them in my bra and sank slowly to my knees. My first blow job was going to be for money! What a night. I totally became a whore. Now I was beginning to see who Ruby was. Ruby was a total whore.
