This line right here has had a choke hold on me for the last five minutes, sir, on god?
quick content warnings: pregnancy talk (PC used to be pregnant), Harper being a right fucking creep, kidnapping kinda??
If I remember correctly, IRL, there's a certain amount of time that has to pass before it's safe to have sex again after giving birth (seems like it ranges from 2 to 6 weeks), and Harper would be mindful of that before doing anything to you. (He doesn't want to damage to your pretty little hole!)
But here's the issue- Harper wants to be the FIRST one to fuck you postpartum. He's been thinking about knocking you up with your next kid ever since you got pregnant with the first one, and there's no way in hell he's going to let someone else get that chance before him. He's earned it, he thinks. He's been so helpful throughout your pregnancy; he's been there every step of the way. He deserves it, he knows. You owe him that.
His solution is to keep you somewhere safe, somewhere monitored, where he KNOWS you're safe. Maybe it's a private room in the hospital, locked behind a keycard swipe. You'll be allowed visitors, at first. He's not some monster; if your loved ones want to come see you, they may. But he doesn't like the way some of them look at you, and he hates the way you look at them back. So the visitor hours grow shorter and shorter, effectively cutting people off. (He's also very particular on which nurses come to treat you. This hospital is full of dangerous people, and, unfortunately, he doesn't have the authority to fire whoever he pleases.)
If people ask, he mentions something about irregular results. Uses a lot of buzzwords, says it's not safe for outside germs to come near you. That they need to be extra careful around you, so it's best to leave you be. To rest.
This moves onto the next part, he needs to keep you in his grasp long enough for it to be safe to fuck you again, to breed you again. (And yes, Harper could get you pregnant in other ways- he could insert his sperm via tube/syringe like he's done to many test subjects before, but his cock disagrees. He needs to feel himself inside of you. He's waited long enough. He can wait a little more, the prize'll be worth it.) He uses similar excuses explanations as to why he needs to keep you with him at the hospital longer. He needs to monitor your levels, your progress.
"Something seems wrong," he'd say, "best to keep you longer, for your health."
It's easier to handle when other people come to him for answers, looking to call him out on his bullshit. They have no power here, he doesn't even have to talk to them, if he really didn't want to. (But he's no coward, he can stand tall with a smile that'll make others shy away.) All it takes is a little manipulation to get them to turn around. He's the expert here. He knows what's best for you, not them. If they refuse, well, it's bad to cause a ruckus in a healing environment, yeah? They'll be kindly escorted out.
It's harder when it comes to you, though. It's not like he wasn't expecting it- he's prepared- but it's still disappointing when you start getting restless. You want to leave, he gets that. You want to go home, to be with your kid. And he understands that. But you can't go yet. Not yet. Not until he gets what he wants. Not until you're ready. But, unfortunately for him, your patience runs out before the timer does, and you're,,, less than happy. And he didn't want to do this (he did, he was just waiting for the perfect moment, the perfect excuse), but your behavior starts to get so erratic and upsetting, so he throws you in the asylum. (Poor thing. So distraught, you're a danger to yourself. He had to step in.) Somewhere even more isolated safe, and he keeps you there for as long as he needs.
When the time comes, after one of your examinations, Harper is shaking from restrained excitement. He almost forgets to hypnotize you, drug you, whatever- he's just so eager to be inside you and pump you full of his seed.
And when he does get to... oh boy, it's heavenly. The wait was worth it.
