Food is laced with aphrodisiacs and character is stuffed full either by force or desire to eat. Basically kinky stuffing/inflation. Things like teasing, orgasms from eating, pressure/discomfort from eating too much, and worry/panic over popping are fantastic. Can go with either side being stuffed or both.

Going from impregnation/magic/whatever right up to about to give birth. Think something like a hour or so of growing really fast with swelling breast and potentially lactation. Bonus if she or her partner gets off to growing and being touched.

I rather keep her still humanoid in shape, so no spheres. Mostly a round belly and blue all over, plus needing someone to juice her to get some of that tension off before she 'pops'. Alternately with someone else who's swelling male or female.

Super down for more vanilla kinks with him, but any of the above would be fantastic. Stuff like handjobs, titfucks, or gentle fucking due to phobias are welcome too.
