   Summary

   Simon is a quiet man. Especially – to Grace’s current frustrated fixation – when they’re…being intimate. He knows Simon gets off, he says he enjoys it, he certainly looks like he’s enjoying himself, and gosh is he pretty, with his curls damp from sweat and his face flushed and glowing. Looking up at Grace with his eyes so soft and hazy with pleasure, panting and – wait, that was the current problem, Grace couldn’t get more than breathy pants and choked gasps out of the man.

   Once – once – he got a breathy little mm! that absolutely haunts him.

   Or: Simon is so quiet in bed, and Grace is a little unhinged about it.
