Jon who’s had a phalloplasty but not the hysterectomy to go with it, so Elias just slices him open and then cuts a slit in Jon’s womb, fucking him through the new hole to make sure his sperm gets where it needs to <3
Jon should be rock-hard the whole time btw. Cock hard and dripping precum as Elias breeds his womb, Jon Knowing the whole time that he’s ovulating, that with Elias cumming directly into his womb like this it’s almost certain to take, and it hurts so so much but the sensation of Elias’ cock sliding through his guts, his wound, the certainty that Elias is going to fuck a baby into him has Jon so desperately hard he can’t even think.
When he’s done Elias should hold Jon’s wound open with his fingers even as it’s desperately trying to close and heal and he should take some lovely pictures of Jon’s open, exposed, fertile womb, walls splattered with cum. Just so Jon can see how well he was bred later <3
When Jon starts to grow full and round with Elias’ baby he should cut him open again. Careful not to damage his womb, of course. But just enough that he can touch it. Run his fingers over the firmness of it, the place where Jon is growing their baby. Sliding his cock into athe wound, rutting against Jon’s pregnant womb, painting his insides with cum as Jon wails in pain, terrified and aroused in equal measure <3
