I gotta agree with chubby, if your metabolism is as ruthless as you say it is, you'll have to fight hard to do some serious gaining, but if you do go through with it, it will be like opening flood gates, easy to get the weight on, but hard to get it back off again.
It may be a better idea to explore stuffing as an alternative, you can still create the illusion of gaining by doing all the fun stuff like pigging out and getting belly rubs but not have to worry about long term weight gain which may become an issue later on.
At any rater, have a look around here, check out some of the girls who have gained a bit and see if it is something you could see yourself doing as well as being happy with it.
Hope it works out for you.
