I will say I do really, really like the idea of Jon having Feelings for Elias, and discovering several years later that Elias is his dad. And the Problem is that before he was longing for Elias to keep and own him, to be permanently tied to him (to breed him, so that Elias would leave a little part of himself behind inside of Jon). He wants to crawl inside of Elias and sit there permanently for the rest of his life. He wants to pick apart and Know every facet of this man. And then he discovers that Elias fathered him and suddenly it becomes so, so much worse… because now it’s like a part of Elias is lodged inside of him, like they belong to each other, like they ARE already tied together… and he’s trying so, so hard to reach for the familial affection he can’t even remember ever having or feeling, and all he can find is hunger.
And they should’ve had one (1) prior hookup. From before Jon knew, maybe. So he can spend every day knowing what it’s liked to be fucked by his dad, to have his father so so close, so warm, so solid, guiding him, knowing his body, finishing deep inside of him… the memory all the more tantalizing with what he knows now.
Or perhaps soon after Jon finds out. Giving in to his sick desires, seducing his dad clumsy and desperate and vulnerable. As if he didn’t know they were related. Thinking he should feel guilty for not telling Elias the truth, tricking him into sleeping with his own son, but he just can’t resist. Trying to keep it a secret but still, still helplessly calling Elias “dad” all soft and shaky as he cums. He’ll feel guilty later. Lying awake in Elias’ arms in the dead of night, skin littered with love bites and his father’s semen still dripping from his cunt. When it’s far too late to take it back.
