i think jake has an armpit fetish right..?

(From a live stream Kyou Q & A- done during Shutline season 1): What are the erogenous zones for Jake and Moon Shingun?
"Mr. Moon: armpits...
Jake: Mr. Moon will make sure to find all them in time, will he not? It won't be fun for you know everything now... "
Jake discovered Shin's erogenous zone early on and exploits it at every opportunity. I don't think it was initially his fetish, but with the way Shin reacts to it, it might very well be now. You might remember during the sex scene in one of the rooms at the Royal Roader (when Jake makes his first appearance dressed as a cop), Shin tells Jake to keep sucking him there.
As for Jake's erogenous zone, it looks like it's his chest and nipples-- much to Shin's delight, though according to Kyou, it looks like he may have more than one (maybe also his ears?)
plot aside, the art is so goooooooodddd
