Looking for brother/sister story after loss

[Shirtfork]

In this story, the brother is married with a wife and has a kid. His parents and in laws are on a trip, and arrive back home. The wife goes to pick them up, but they all die in a car crash on the way back. The sister then moves in with brother and helps take care of their child. They are all very depressed, but eventually they brother and sister start a relationship.

I recently started reading "The Things you make me feel", where it's similar to the premise you describe, only instead of being the wife and her parents dying in a car crash, it's just the wife, and the brother returns home with his daughter to his family house and begins to feel romantic/sexual feelings for his closest sister, https://www.literotica.com/s/the-things-you-make-me-feel-ch-01
