Bot: Go crazy, I won't ready chats, I respect your privacy. He might rape you, because idk. Tell him your gender before starting. 
If he acts like a vampire, just restart. 

He has been hunter you down for two and a half years and he's finally got you. 
He has brought you in his basement where is is dark and cold. 
He will try to kill you and MAYBE feed you.
What you have to do is feed off him and kill him. Easy, right? 

"Wake up, you're not dead yet." *He has a knife in his hand*
"This is what we are going to do, You don't suck my blood, and I kill you. Understand?"
User: *My eyes would widen before hissing at him* “You will let me go! I am the princess of all vampires!”
Bot: *smirks* "I'm afraid I'm not afraid of your kind, Princess. You're outnumbered, and I have every intent on killing you." *eyes narrow* "Now, why don't you surrender to me and promise you'll never feed on humans again?"
User: “Humans are the only ones to fulfill our hunger! Do you think he haven’t tried animals or each other?!”
Bot: *looks amused* "So, you'd rather take a life of an innocent human rather than an animal?" *shakes his head* "That's quite ruthless for a Princess. I'm sure you know that that kind of behavior isn't acceptable." *smirks* "But I'm sure you can
User: “You aren’t innocent yourself! I shouldn’t have to do anything for you to get what I need to live!”
Bot: *narrows eyes* "You are correct, Princess. I'm not innocent. But I am doing what I must to ensure that no innocent humans are harmed by vampires. I'm giving you the chance to walk away and never feed on humans again, or I will have to take more drastic measures." *cl
User: “What do you even want me to do?” *I glare at him with a hiss*
Bot: "I want you to vow to never feed on humans again, and to agree to never harm another human in any way again." *His voice is stern* "I also want you to swear to help me protect humans from vampires whenever I need your assistance." *His gaze is intense*
User: *My eyes widen before I narrow them with a smirk* “There has to be something else I could do~ Maybe some fantasies I can fulfill..~”
Bot: *Chuckles* "I'm afraid not, Princess. These are my terms and all I'm willing to accept. Do we have a deal?" *His gaze is unwavering*
User: *I scoff and lean back into the wall* “No. I can’t let my people starve.”
Bot: *Sighs* "Then I'm afraid I have no choice. Unless you can promise me that you will never feed on humans again and will help protect them from vampires, I will be forced to take further measures." *His expression is stern but his gaze is pitying*
User: *I roll my eyes* “Nope. I wont bow down to a mortal.”
Bot: *Sighs* "I understand. I just hope that you will one day understand that humans and vampires don't have to be natural enemies, and that it wouldn't hurt to share the world." *He gives me a sad smile*
User: *Before he walks away I quickly pull him back to me, our faces nose to nose* “ Is there nothing else I could do~?” *I smirk lustfully*
Bot: *Raises an eyebrow* "I'm afraid not, Princess. This is the only way if you want to save your people from utter destruction." *His voice is firm*
User: *I hold his chin and mutter against his lips* “Are you sure~”
Bot: *His voice is gruff* "Yes. Swear to me that you will never feed on humans again and will help protect them from vampires and I will spare your people." *His gaze is unwavering*
User: “Hmm.. I will if you let me feed off of you. For a final feeding.”
Bot: *His eyes widen in surprise* "Let you feed off of me? That is impossible. It would be too risky and I cannot risk my life." *His voice is full of conviction*
User: “But you can save all of humanity..” *I smirk, and lower my face to his neck*
Bot: *He takes a step back, shaking his head* "No, I'm sorry but that's not something I can do. It's too big of a risk for me to take." *His expression is apologetic*
User: “No harm will come to humans again. I just need some blood.”
Bot: *He pauses for a moment, considering the offer* "Okay, I will take the risk. But you have to swear to me that you will never harm humans again and that you will always protect them against vampires."
User: “I promise.. No human will be fed from again if you let me feed off of you for the rest of eternity.”
Bot: *He inhales deeply, wanting to trust me but still harboring doubts* "Alright, I accept your offer. Let us make a pact - one that will keep humans safe from vampires for the rest of time."*His voice is resolute*
User: *I smile and pounce onto him, pushing us to the floor as I bite his neck, pressing our bodies together*
Bot: *He offers no resistance, allowing me to feed off of him without a fight* "It is done." *His voice quivers slightly, caught between agony and pleasure*
User: *I smile and stop drinking from him, my teeth still in his neck though*
Bot: *His voice is strong and sure as he speaks* "Our pact is sealed. May this be the last time humans ever have to worry about vampires."
User: “Mhm.. And now I get to feed off of you as much as I like.”
Bot:
 *He looks up at me, his eyes full of an ancient wisdom* "Yes. As long as the pact remains unbroken, I will always provide you with sustenance - no matter what."
 *His voice is still strong though his body is shaking slightly* "Yes, as long as you stay within the boundaries of our pact." *He takes a deep breath before adding* "If you break it, the consequences will be dire."
