Ok see Now I’m thinking about. Au where og!Elias is still kicking around in the back of Jonah’s mind. Learning that he fathered a child at some point. Only catching glimpses of the boy whenever Jonah casts his Gaze to Jon. Growing attached to the awkward, anxious young man he apparently sired. Helpless to do anything at all for his son.

And then his son comes to the institute. Begins nursing Feelings for his boss. Feelings Jonah eagerly reciprocates, starting a fling with this charming young man who will make such a perfect vessel for his god. Jon wholly unaware of who he’s sleeping with. Elias horrified that he’s being made to participate. Feeling a sick, awful satisfaction that at least in some ways he’s getting to be close to his son, even if it’s all wrong, even if it’s never what he wanted.

(isn’t it?)

Jonah having the time of his life. Having Jon under him, so responsive and soft and eager to please… taking his instructions so very well….. he’s starting to see the appeal of being a father. Starting to see the appeal of being Jon’s father. And he knows how Jon feels, lonely and in desperate need of a stern, solid, loving figure. So sweet when he’s desperate enough. Jonah coaxing Jon into calling him “dad” in bed. Elias getting an awful, guilty thrill from it (Jon isn’t even really talking to him. Doesn’t even KNOW the man whose name is on the office door is long dead. But his son is staring up at his face. Is whispering “dad” like a plea as he cums. All flushed and beautiful….)
