This definitely happened to me.  Six years ago I was a skinny 150 pounds ( at 6'0" ).  Initially I didn't intend to gain, but eventually I decided to try it out because I had already spent years unsuccessfully searching for a feedee and I needed an outlet for this fetish.  And now I'm closing in on 300 pounds.
