Searching for this story

It seems the post was purged, so here's a copy of it:

>I once read a wonderful story on literotica about a girl with a dick and she and her sister (who might be either adopted or her step sister I can't remember) and it's multiple chapters and one they go to the doctors and the doctor examined the futa and she got her to Cum all over her and while that happened the mom and sister watched and the sister fingered herself through her pants
>The dickgirl/futa hides her cock by putting it in her pussy and at one instance her sister just rips it out of her pussy in front of their neighbor who is a girl.
>Uhh let's see what else I remember, she was going to have sex with her boyfriend in the beginning but he found out that she had a dick so he broke uo with her and she went home and I think her sister found her
>Her her sister and their neighbor all do it at least once
>God that had to be the greatest story I had read and that was like 7 years ago and I never found it again so any help would be greatly appreciated
