Ah, the things you can pick up at a Con. The following if from a multi-story doujinshi called "Super Best" I don't know the title of this story though, but I think it's pretty much self explanitory, even if you're like me and can't read a word of Japanese. Enjoy!
Please PLEASE don't take any of the following images! I spent a while cropping these and such, so I'd appreciate it if you didn't steal them. If I find these on any other page I'll have to send a crazed chibi Goku after you... and you wouldn't want that. If we have an understanding, go on ahead! ^_^
