kink fat
One of my favorite things about size is not fitting in places. Likely because IRL I am excluded from things due to size. So playing with it in kink spaces lets me own it, sorta. Being huge and squishing against hallways, needing help through even extra large doors, needing special magic or equipment to get places...
kink fat, ageplay
Also, a HUGE fantasy of mine is growing up huge. So... going to school while barely fitting in the hallways, squishing up against the other students by accident, bashfully apologizing and making everyone late, needing to just sit in the back of the classroom, but everyone still knowing I'm there. (doubly so if I'm wearing some sorta squeaky, stretchy outfit due to not fitting in anything else)
