I don't "trade" pictures, nor do I send them on request. If you haven't figured it out yet, I work on-line, and I have thousands of free pictures and videos available in a number of places. In fact, just go back to the main page here, and you'll get all sorts of stuff of me for free.
This is also how I make my living. Would you walk into a store and ask for something for free? Or a free dinner at a restaurant? It's really the same thing.
You are welcome to send me any pictures you like. My preference is CUM pictures and I also have a real fetish for Bi-Guys. I love when a guy is man enough to suck another guy's cock! ;)
