Looking for incest story about 18 to 30 years old with slow build up

[Rus_]

The age between the main characters between 18 to 30. By slow build-up, I mean is the sex doesn't come until much later in the story (not rushed) like most stories in Literotica. I don't get why people read those, for stroking? I'd rather watch porn, lol.
