Idea for a futa incest rp

The idea would involve you to play a young futa sister while I play a femboy older brother. (roles can be reversed if wanted.) the parents having died left only the older brother to take care of his sister. The sister would be much smarter then what a kid her age would normally be but doesn't let anyone know.

The rp would start with the brother having been fired from his job about a week ago and not been able to find another. Money was getting tight for them meaning they were possible to lose their home. Since the older brother isn't able to provide properly that would leave the sister to try getting money. Since she wasn't old enough to get a proper job she would have to use other methods by making an onlyfans. She would need to do something that would catch peoples attraction to get any amount of decent cash. She decides that she'll knock up her older brother and make the OF page into a progression tracker of the pregnancy.

From this point it could go a few ways on how she manages to make it happen. 

I look forward to hopefully getting a few who want to try this out.
