Gaining

Very common fantasy. See: fantasyfeeder.com/cms/infusions/forum/view-thread.php

Same XD seems fairly standard tbh.

It's a fantasy that starting to win me over the more I think about it, or something similar.

Umm, yea. This fantasy crosses my mind at least twice a week...sometimes more. Usually involving crushes from here, past high school crushes etc who bust into my room one night while I'm asleep, tranq me and take me to their lair to fill me with all kinds of food until I'm so fat my own body pins me to the floor.
