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.
Elias should go into rut btw. Spends the first day luxuriating in being mated by an omega in heat and letting Jon take what he wants, then waking up in the dead of night in the beginnings of rut and so so hungry. Thinks for a few moments about leaving but decides he doesn’t want to. Pushing Jon’s unconscious body so he’s presenting for his dad, not wasting any time before thrusting deep inside. Jon waking up to his father mounted on him, pounding him into the mattress, unable to do anything but take the breeding his father has been generous enough to provide <3
Their cycles don’t let up for several days. I’m imagining Jon waking up in his father’s arms, clear-headed for the first time in days. Hiding his face in his father’s neck and inhaling their mingled scents. Feeling so, so ashamed, because he should feel guilty. Should feel horrified by what they did (what HE did. Forcing himself on Elias like that…) but. He doesn’t. Instead he feels good, feels satisfied. Present and awake and real in a way he hasn’t in a long, long time. His instincts satisfied that his mate has claimed him, has bred him thoroughly <3
I think after this Elias should put Jon in a chastity belt <3
He more than enjoyed the encounter, and there’s an instinctive part of him that’s wholly satisfied from breeding his son, claiming him as his mate (making it clear that Jon belongs to him in every way… son, mate, the bearer of his children……) but losing control of the situation like that was… disquieting. And he think Jon could do with the little reminder of Elias’ authority. And, tracing the shape of his son’s thoughts, Elias can tell that a little “punishment” might help settle Jon. He shouldn’t be ashamed of taking what he wants, pursuing his hungers and desires regardless of morality. Elias doesn’t want him feeling guilty for that.
Besides, he’s certain they’ll both enjoy it <3
Elias ordering a belt for Jon early that morning, with same-day shipping. Ordering brunch for them too, because this body isn’t as young as it used to be and Jon was a very demanding partner. Keeping Jon close throughout the day, scenting him, and purring to him, even hand-feeding him. Letting himself follow his instincts to care for his mate after a long and tiring heat. Because he wants to. Knows it will help them both.
The belt arrives in the late afternoon, and Elias separates from Jon briefly to go pick it up (the distance, even for a few minutes, is painful).
He half walks, half runs back up to Jon, who starts chirping for attention and affection as soon as he sees his dad, his mate. Comfused but compliant when Elias orders him to lift his legs (squirming already, wondering if his dad is going to fuck him again). Elias slides on the belt, locks it in place before Jon even processes what it is. Crawls into bed to hold his son close <3
He chastises Jon for being so irresponsible with his body. Letting himself be mated and impregnated by his own father… and when he’s so young too. Surely he knew better. Kissing Jon’s forehead and stroking his back as he speaks <3. Tells him that the chastity belt will stay until he can prove that he can be responsible. Can make good choices and not let his instincts overpower him. He can’t afford to be so irresponsible, not when he might be carrying Elias’ litter…
Jon begging Elias to take it off, please, he can be responsible, he can be good. Letting out the little chitters children make to their parents when they want something. But Elias is firm. Jon is to wear the belt until he can prove he’s learned his lesson. No sex or touching himself without his father’s permission. If he wants to cum then he needs to earn it <3
Elias is going to enjoy the next few months very much.
