General

I like to role-play rapid male weight gain.

Basically I create a character that I write up the actions and reactions for, and put him in a situation where he'll get really fat, really quickly.

It's basically enacting a story or a fantasy between two or more people. Usually on this site, you would enact some situation where you encourage or spur on weight gain in another even if it would never be possible in a million years to actually make something like that work out.
