Hmm, let’s see:

Kara: Softer in stark contrast to Eden’s assets, getting snatched up by Kara wouldn’t be too bad in terms of the lack of space, though any attempt at escape would be futile as Kara would keep pushing you back in.

Mei: As said before, her vast chest is practically “Marshmallow Hell” made manifest, though if you fall into her canyon-like cleavage, chances are you’ll have to wait for a rescue team to pull you out. It’s happened before.

Cassidy: Like getting caught up in the sea’s undercurrent, but replace the water with fat. Getting sat on results in you needing to constantly push back against rolls and layers of swollen skin attempting to envelop you in their squishy embrace. Comfy feeling though.

Renée: Thankfully the least bothersome, as sinking into her gargantuan gut almost always causes her to go into a fit of giggles, effectively pushing you back out. Glad her hugs aren’t as deadly as one may think.
