This picture inspired this fantasy:

I travel to Thailand and I go to a bar in some seedy neighborhood. Unknown to me, someone puts something in my drink. When I wake up, I realize I've had surgery. A lot of surgery. I look in fact like the ladyboy in the photo. I'm recovering form the anesthesia so I can't even get up properly, when a man walks in.  Stark naked. With a big erection. He grabs my hips and fucks me right there. As he fucks me and grabs my new tits, I get an erection. 

 A month later, I'm pacing in a hotel room, wearing high heels and little else, waiting for a client. I now work as a shemale prostitute specialising in foreign clients.
