Never really considered the sounds that would accompany the current cast, but given their growths and the hijinks they get into, it’s probably be something like this:

Eden would be followed by rumbling, heavy footsteps, especially with how heavy her ass and legs are, occasionally following by loud crashes and creaking should she get caught in an uncomfortable position.

Kara would always have a satisfying slosh as she sways her massive milkers around, they are never empty after all.

Mei would emit a low wobble across the city whenever she’s on the move, as each precarious movement sends ripples across her mountainous mammaries.

Cassidy, given their habit of stuffing themselves senseless, would always have a very active stomach, constantly growling and churning as if begging to be swollen with food once more.
