Like so many other things, the flow of words is something Marcus alone has unlocked in him; he's surprised too, to find how easy words trip off his tongue (embarrassing or not). Dan meets Marcus's gaze and he feels laid bare, and about the only thing that keeps him from coming in that moment is the joyful bubble in his chest. "I've never--" he gasps, "sweetheart, fuck, I just--"

He gives up trying to control his mouth about then, because the only thing left to do is let the pleasure wash through him, to enjoy all of the feelings Marcus is giving him.

"I--" he stutters out a warning, and he doesn't get any further, because he's coming, and he couldn't stop it if he tried. He's not even sure what kind of sounds he's making, just that they feel like they're clawing out from inside his chest.
