Declan has the decency to look momentarily contrite after Ronan's small ordeal. He tries not to think of how it felt to slide against the back of Ronan's throat or how good he looks all flushed like that.

"Here." His voice is quiet as he guides Ronan's arm so that his brother's elbow is against his hip. "Lean your weight in, promise I can take it." It might not stop Declan altogether if he gets caught up, but at least Ronan will feel it coming. "Move your hand a little higher. And I'll uhm... try not to do that again."

He lets his fingers brush back through Ronan's hair; his other hand remains tangled with his brother's. He won't let go until Ronan wants him to.

"Try again. Nice and easy."

And he'll try to ignore how much he's aching to come.
