the sharpness holding him in the moment, intensifying the sudden truth of Forrest's mouth on his dick

I love your phrasing, and I particularly love the surprise of this fic. Surprise for me in how much I liked it. I'm often not a fan of PWP but to me this is more than that, there's more going on here that you've beautifully scratched the surface of. It has such a truthful ring about it too. Lovely piece.
