I keep thinking about Caleb - focused Caleb, who isn't shy about sex but doesn't really think about wanting it too often, who has had sex before but maybe has never used a sex toy before - somehow stumbling into possession of a sex toy of some sort (in my head I'm imagining a fleshlight, but it can be anything) and, well, curiosity gets the best of him.

(Really, I just want Caleb masturbating using a toy)

+ thinking about one of the mighty nein (essek included) while he does it
+ feeling embarrassed about it at first, but becoming more and more shameless the more he gets into it
