This story got pretty dark, anyway, here is another translation.
Again I used machine translation to get a rough idea of the story and then polished everything into proper sentences.
I also removed the bones sticking out at 14 and 15, this CG is already dark enough.

It definitely has nerves. Go eat too much chilli on an empty stomach, an antibiotic pill or a poorly chewed piece of apple and tell me the stomach has no nerves.

It's crazy to think this is actually making out pretty good in the hentai world. Trust me sister, this could have gone a LOT worse.
