Have not seen in pointed out.. All Orgins Have incest via the Katelyn Story Line ... Both PC's are at least half bro/sis to Katelyn, so using logic...Daddy was out planting seeds or Mom is the Noble Whore running the club in Summeredge.The Farm origin has incest as well. Your mother works at a brothel in Slinsk, and with a little chatting you can sleep with her..
