Ignis is just starting to really relax underneath him, and Gladio takes that as a sign to keep going, to take what he wants. He can live without burying deep into his lover for now, but the all encompassing heat of his want makes him need Ignis in ways that just cannot be explained in words.

He growls low, happily picking up the pace. He steadies himself so that he can change the angle a bit better, thicker, canine cock making it easy to find Ignis prostate. It doesn't help much with the ache of the stretch though, but hopefully the pleasure outweighs that. The obvious and raw, eager way Gladio needs him shown in each thrust, in each dazed words of love he spills from his mouth.

Ignis' name gets strangled into a extremely wolven groan of pleasure, hands roaming Ignis body as each thrust pushes him deeper into their sheets, Gladio's hot breath panting against his neck a show that yes, even though it is strange, that it is different, it is still his mate, and Gladio is there.

And Gladio can always be pulled back from the edge of his instincts by Ignis.
