It's been seven hours and no one's stepped up, so I guess I'll give it a shot. I hate feeling like I'm monopolizing these kinds of threads, but come ON people!
Anyhow, how about some kind of elemental mage feeling a bit of elemental blowback? A water mage might get a really full belly, while the earth mage could be heavyset all over, wind would become ballooned, and fire, well, a fire mage would just become smokin' hot with a big hourglass expansion (optional belly expansion too, so long as it's sexy!
)
