Looking for father daughter story

[Irongrowth]

Read it last year and now I've searched with every part I could remember and no luck, hoping someone else here will remember more of it or the name/author.

It has a drunk daughter filming herself giving her dad a blowjob on the couch while he's sleeping, she ends up screwing him but forgets the next day and doesn't find out till she uploads the video to her computer. She ends up having his kids and the mother approves because she wasn't able to anymore.

I know I'm missing parts and I'm guessing that's why I can't narrow the search enough to find it. Thanks for any help finding this one.
