Cougar can't help the smug pleasure that rises up when Jake reacts the way he does, using his palms to give him more room to work, nudging Jake's cheeks a little further apart as he lets this moment wash over him, thinking of all the years that he didn't think this was possible. If anything, it makes him even more determined to make this good for Jake, because he wants him to want this all the time.

So that's why he turns unrelenting with his tongue and mouth, refusing to give Jake any gentleness.
