Saving the Big Sister (One-Shot) (Bioshock)

Does anyone remember the beautiful world of Rapture? With the old game known as Bioshock? Everyone who does remember the Big Daddies and the Little Sisters right? Well, who remembers from Bioshock 2 Big Sisters? After remembering about them, I thought of an interesting story to try and do if anyone is down for them? Of course despite it being a One-Shot, as always, can be open to a full on story!

Story is that I will be playing a OC who got the unfortunate/fortunate chance to be stuck within rapture. While down there, he needs to try and find a way out of there and back to his world above the sea. Though, while venturing deeper within the city, MC would end up finding one of the residents down below who hasn’t fully lost their mind. She has a request. 
 

Her request is to save the Big Sister(s) and bring them (or one) back up with him to the surface. They shouldn’t have to live the life of violence, having the parasite take over their minds. But how is he supposed to do that? Easy! By using one of the Adam’s she created, it would give him the chance to purify them and take the parasite out! All he has to do is defeat them in battle….and have sex with them. Yes, he has to have sex with them and climax inside of them cause the Adam will make his seeds have the necessary antidote to expel the parasite from their body to make them normal again. 
 

Of course, despite them being normal, who’s to say they wouldn’t help him in battle? Either way, what choice does he have right? Maybe they are pretty underneath it all right?

Of course, can be talked too about this idea! Is there any takes who want to revisit the beautiful world of Rapture with me?
