Alt: Elias coming home from an event in a nice suit and Jon tearing it off of him. Kissing and biting every inch of revealed skin he can get his mouth on. Elias totally overwhelmed and letting Jon just take what he wants and so so hard as his son rides him panting and desperate.
Maybe omegaverse. Jon in heat, scent-marking his father aggressively, his nice new suit reeking of desperate omega. Of Jon badly needing to be mated and bred. Slick staining the pants where Jon couldn’t stop himself from humping Elias’ leg. Elias’ clothes making their way into Jon’s nest. Drenched in the scent of taken and breed me and MINE.
Elias calling in and trying so so hard to keep his son quiet, to not moan as Jon humps his knot, because heat has made his boy terribly aggressive and he knows he isn’t going to be leaving the nest until Jon’s been good and pupped with his litter. Letting his son mate him again and again, overwhelmed by the sensations, his discarded clothes inevitably stained with his own cum as it leaks from Jon’s used cunt.
