Well, to be honest, it went downhill and was drifting away from incest, in my opinion, in the brief time it was there and being updated. It was called Kara Comes Home. Here is the plot in case it gives anyone any inspiration (you never know).
In short, the oldest, most responsible daughter (Kara) in a family of feedee slobs moves back in with them after a falling out four years ago and gets drawn into their lifestyle. She has a mother (Cassandra) and two younger sisters, the youngest (Layla) being when she moves back home. I think Kara is supposed to be in her late twenties or thirties and no idea about the mom or the middle daughter.
The original cause of the falling out had been her mother's marrying a baker feeder (Alex) and subsequently blowing up fast and getting more slobby, plus the middle sister (some similar name like, idk, Sara) getting married to the baker's feeder assistant and going the same way, and finally seeing her mom deliberately drawing the youngest sister into the same lifestyle just, apparently, for the thrill of it.
But when she moves back in, the middle sister seems to have moved out to live with her husband, and the household now consists of Alex (who is at work all day), Cassandra, and Layla. Cassandra is like 700+ lbs and Layla is 360s or so I think. Somehow, Cassandra is slightly mobile, but mainly Layla takes care of and feeds her, and Cassandra feeds her back, and although there wasn't an explicit sex scene they basically feedist dirty-talked extensively about getting fatter and fatter with no limit. Incidentally, the house is a complete sty, and the mother and daughter go around naked and messy at home.
Kara is shocked and appalled but Cassandra gives her stern ground rules for staying there, essentially roping her into caring for and feedinf her along with Layla. Alex still hadn't appeared and in fact never did before it went down.
The story then time skipped a bit for last chapter or two before it disappeared. Kara's whole corruption was basically already done with, she was out of nowhere admitting to herself that she was starting to enjoy all this and getting fatter. It felt very rushed. There wasn't any further incest, but rather suddenly a fresh feeder baker's assistant appeared delivering pastries and she basically throws herself at him instantly. Sooo, I think it was heading in the direction of wasted potential anyway.
It feels to me like the author was inspired by the earlier chapters of "The Fall of Madelyn Beckett," which is on FF here and also on deviantart I think, and still being updated. But that story has taken several wild turns and is slightly less incestuous than Kara comes home..
