Istvan's Bollock Dagger

And, while I have no idea if James communicated that intent to the sound designers, it seems like it's reflected in the sound design with Rocky's echolocation noise.

He makes this sound when he's trying to "look" closely at something, usually objects. The cool thing is, he also does it when he feels insecure. Whenever he gets vulnerable and uncomfortable he pings this noise at Grace. It's like looking really closely at someone because you're anxious to know what they're thinking.

He goes from doing it before and after every sentence, to less and less as they get familiar with each other. He's suddenly doing it non-stop again for the whole one-way trip conversation, when Grace is actively hiding his emotions from him. It doesn't show up again after that until the end when he hesitates before calling Grace "brave".

Rocky is discussing human porn with a very mortified Grace when he suddenly asks "Rocky see videos of mating ritual involving teachers, Grace teacher on earth participate in mating ritual question?" and Grace stands confused for a second until he realizes Rocky has been watching videos of teacher kinks.

Rain: starts

I think dexterity would be a kink even removed from molting. Deft little fingers doing a good job is very appealing to everyone! Everyone will be listening to Grace's soft nimble lithe fingers with much interest when he arrives...

I think a good bit of the interest in freshly molted shell for Eridians might be the danger. Not only are the shells of the freshly molted soft and easily damaged, they are more exposed to the pathogens in Erid's air. They are so easy to potentially harm, so soft and vulnerable and exposed... like prey, or like a baby. Many kinks start from things like this. So easy to damage, the potential for harm or restraining yourself so you don't cause harm... The power this gives you, or that it gives the molted over the unmolted is really interesting.

And then of course the softness itself is hot. You can hear into it so easily! when you touch it, it gives way! Does this leave a permanent impression? Can you mark your partners this way? Harming yourself while soft might be the only time you can feel this specific kind of pain. That might be its own kink!
