ChannelDaughter Swap
Aubry and Violet are two friends who are also very popular fanfiction writers, but their audience is asking them to write more smut stuff. The girls are clueless about explicit content, so they go to their stepdads, Peter and Sergeant Miles, to learn about sex and some experiences to write about. Sergeant Miles and Peter think it's easier to just teach them, so they fuck each other’s stepdaughter, yet things quickly get out of hand.
