Gladio didn't look away as Prompto took him, pupils wide and making his eyes that much darker in his arousal. It was impossible to miss the way Prompto's throat flexed around him, something not unfamiliar from the past, but feeling Prompto doing it of all people felt wrong, yet at the same that wrongness somehow made it... more.

He groaned low and when Prompto pulled back, he took the chance to still his head and give a few shallow thrusts, testing the waters. "Fuck, that's good, babe." The words just came out of his mouth without much thought behind them other than the truth of them. His hand shifted and his thumb stroked over Prompto's throat. "Willing to choke yourself for me? Mm. Curious to see just how far you'll make it down here." His thumb slid down the length of it.
