I used to ball bust myself, it sounds kinda weird, im sure, but it can reall rock, i did it cause you cum, and feel imense pain at the same time. My fav way, was to take a rubber band, and double wrap it around the base of my scrotum, so as to put buth my balls out in front, and unable to escape the pain, cause they were stuck, then i would sit them on the part of the toilet you sit on, and drop the lid, this was extremely painful, but not enough, then i would start taking things in my bathroom, i took out an entire drawer of tuff once, and pile it up on the seat so it was crushing my balls. another fav was, i would use the rubber band again, and but my balls between the door and the wall, above the hinges, and try to close the door, either slowly, for a squeeze, or slamming it, for the most immense pain, you can really get. the best squeeze of all though, is to take a chair, use teh rubber band trick, lye on your back, and set a chair leg on your balls. These are the ultimate DYS ball busting techniques. BTW, i dont do it anymore, and i feel like shit, that why im posting, to try and get it off my shoulders.
