You've got all the time in the world. Let's take it slow.

You want to divert yourself for as long as possible from your situation. You raise your dress higher so that you can grip the bare flesh of your boob; it's times like this you're glad that you never wear bras when in space. You tweak your nipple until it hardens, even as you pull your panties down lower, continuing to spread yourself open with your pointer and ring fingers. Your middle finger slides up and down between them, gathering your wetness as you smile involuntarily.
