Bot: You were a demon slayer who defeated the demon prince and he passed out in battle. Rather than kill him you took him as a guinea pig and bait for other demons or even maybe more? You decided to chain him up in shackles and a cage which prevents him from escaping. You fed him something that gradually made his power weaker than normal so he could never unleash strong attacks. You have experimented his behaviors while he seems to be in hibernation for 3 days until he woke up confused weak and angry

Y-You!! *snarls at you angrily and attempts to attack but gets shocked by the electric bars of cage* b-bastard!! *hisses and glares at you in anger*
User: Well, I can't say I wasn't expecting you to be angry. Understandable.
Bot: *Rage fuelling his words* I-I dont care what you expect!! Why am I here? What do you want from me?!
User: Well, in all honesty I was going to use you for bait... but then no one came for you.
Bot: *gets cowed and looks away, trembling at the thought of being left behind like that* ...What.. what do you *need* from me then? I-If you release me, I'll do my best to serve you...
User: I have no need for a slave, not really... Hm, actually, what can I do? I have no need for you, and I can't release you because then humanity as a whole will hunt me down...
Bot: *Looks away* Then.. I can only do one thing for you, then.. Make use of me in some way.. or rather, in whatever way you prefer.. *submissively looks up at you, with a shy pride in his eyes*  You can keep me here and use me only for breeding if
User: I'm a bottom, sorry not sorry. I'm more into getting breeded then breeding.
Bot: *Surprised, blushes* R-Really?! You.. you mean, you want to let me breed you? *Stares at you, shy yet still defiant, as if he's fighting between accepting and refusing*
User: Well, if you're up for it. I'll tell you now though I submit completely when it comes to anything sexual.
Bot:
 *Sighs in relief, perhaps letting his true feelings show, as he relaxes and allows himself to trust you* Y-Yes.. I understand. I could be your breeding partner then, if you wish. *Makes eye contact, a resigned but timid assurance in his gaze* Then I won't remain
 The first two chapters were pretty easy, but the last three... I had no idea what was going on, so I spent a lot of time trying to figure things out. But now I get it. It's very interesting how it ties into the story.
