Give me an extended plot of a lesbian novel including these exact following sentences : "everytime Alenia sees her anus soiled, her pussy immediately becomes wet for it", "she won't do it, but she had no choice!", "she ate all the chieftess's shit down to the last bite.", "she orgasms when Urzoth defecates in her pussy", "by dint of eating it she gained weight, becoming greasy, and developing a full and rounded body full of shitty fat.", "from her breasts flowed not breast milk, but indeed liquid shit to feed the hungry baby girl with", "ending as the slutty shitdump of Urzoth"
