My boyfriend recently came across a video of a woman's breasts being inflated with saline using IV needles. We've discussed the possibility of playing with saline injections, but haven't found much specific 'how to' guidelines on the web. We already play with needles, but would like to know more about the nuts and bolts of getting the saline in the right spots - and not in the wrong ones. Also, we're wondering about medical issues or cautions. Of course, I'm also interested in knowing what the experience of getting saline injected into part of your body is like for those of you who are experienced.

Any information, links or suggestions will be appreciated.

Thanks!
