I'm So Ashamed But I Know I Will Do It Again.

I am an older white guy and Ive been a crossdresser most of my life. I've managed to keep it in check until recently. I got to the point that I was ready to go out in public "dressed" and decided to go to the adult book store because I knew I would not too out of place. I dressed,went to the abs and every thing was going well , I was at ease just sitting watching the movie. A heavy set black man came and sat beside me. In just a short time he had his cock out stroking it. I had never seen a black man's cock in person and I was taken by surprise at how turned on I was. I watched for awhile and worked up the courage to put my hand on his leg,he stopped stroking his cock and I put my hand on it and started stroking it. He must have liked it he leaned back and watched as I jacked his very thick cock. I'm no stranger to sucking cock but they have been white and average to small in size. I leaned over to take his cock in my mouth and he gently pushed me back, not letting me get my mouth on him. he stood up and dropped his pants, bent over slightly and spread his ass cheeks, I though he wanted me to fuck him so I whispered that I was a bottom. He said I know. If you want my cock you have to lick my asshole first. I was floored, I had never done anything like that before in my life. He just stood there in front of me his plump black ass inches from my face. He was stroking his cock again and I wanted to suck it more than anything . After a little while I spread his ass cheeks and looked at his hole then I moved in and buried my face between his cheeks and started licking his asshole with my tongue. I that I would be disgusted but I felt myself cumming in my panties,not even touching myself.I started to really get into it and began to tongue fuck him, licking and kissing his ass and loving it. He pulled away and turned around and put his hard cock in my mouth. I began sucking him like a whore wanting to feel him fill my mouth with his cum and he soon did. I was so horny my mouth was full of cum, I didn't want to swallow just yet it tasted so good. I did swallow and began sucking him again and after awhile I had another mouth full. He pulled up his pants,zipped up and said your a very good cocksucker and handed me a piece of paper, it had his phone number on it. I felt proud that I had pleased him so well at at the same time I was ashamed for having desired eating his ass like I did. I thought,I will never do it again but I knew I would,I already wanted to do it again. I would be calling him soon,I knew it and even it was so nasty, I loved it.
