Julia resting some of her own hands on her own hips, like you’re supposed to with hands-on-hips-poses. You could also make a version of this where her bodies are facing each other and her hands are resting on adjacent hips, but I feel like that would look too much like a lesbian couple trying to hug each other by their butts.
I think hive minds are underrated as a kink. Even more underrated than nipple mouths and dragon centaurs. As a draft for this description, I wrote a whole paragraph listing reasons why, but then I thought “who would want to read a sales pitch for a kink?” The TL;DR would be “They’re a natural extension of what you can make with extra body parts and detachable body parts. They’ve got the best of both worlds and you can do some lovely things with them.”
