Established relationships squick me so I almost stopped reading at one point but then I scrolled up and saw the warnings and remembered why I had clicked on it in the first place so I kept reading and HOT DAMN, the fisting! Was so hot! Just, just the pacing, and how they're desperate for each other and so turned on, how they've obviously been thinking about this so long, but the nerves, but they trust each other so it's beautiful... I can't think of a better pairing for this kink!! So spectacularly hot! <3
