The story starts with a woman picking up a hitchhiker from a rural area. After bringing him to her home for the night she introduces her family - three daughters- young twins and an older one. He sleeps with the older daughter (no guro I think) and in the morning they spitroast the mother for breakfast. The story was consensual and the man was a stranger to the family. I think I read it the middle of one of the treads here but I may be mistaken. I will be very grateful if anyone can help me out finding it.
