Looking for incest/impregnation/cult

[LoriaFrost]

I'm looking for a story I read a few years ago on Literotica. A father and daughter moved to a new community where children were raised collectively, and the women of the community were impregnated anonymously. Specifically, they were bent over and covered from the waist up, lined up, with their arses exposed. The men would take it in turns to fuck them, bareback, coming inside. Neither man nor woman knew who they were fucking. There's an element of incest in that the father doesn't know which woman is his daughter.

I have tried so many different searches and cannot find this, does anyone know this story?
