Desperate to Survive in an Apocalypse (MxF)

So, because of Resident Evil 9, kind of had this idea running around in my head now. 
 

Pretty much, the basis of this idea is that YC (who is female) is trying to survive in an apocalypse world. But, she isn’t the best at it. She isn’t a fighter as she doesn’t have any combat or weaponry training. She needs to find a place to survive in without having fear of someone attacking her, infecting her, or worst! So, she tries to find a place to hide. 
 

Only, she manages to find one. MC (who is a male) who is offering her a place to stay with him. The place is well guarded, has food, and seems like he is able to hold his own! But, there’s a small problem. He is a massive perv! Saying he will only allow her to stay if she is willing to put out for him, which of course only means one thing. 
 

Normally, YC wouldn’t because he is NOWHERE her type, but, if she doesn’t, then that means she has to fend for herself again. 
 

What would it be? Suck up her pride to survive with him by letting him fuck her, or she goes out and try to survive herself. 
 

Summary: Basically, I want this to be almost like another “Opposite Attract” rp idea where MC is someone who she wouldn’t find attractive. Like an overweight male, elderly male, hetereo femboy, or maybe if YC is an older MILF looking women, a perverted young adult male who is interested in her. Something along those lines where eventually, she caves in and just enjoys herself. Not needing to fend for herself but rather, having to let him fuck her till she is pregnant. Creating a family during the apocalypse where he takes care of everything else. 
 

Here’s some looks I’ll be going with:

I would say I would love some OCxCanon, but I am fine with OC x OC if anyone is interested ^^.

Canon Girls I like to see possibly:
