Prompt: "There's a lot of poly shipping here, so I wanted to see a story about someone cheating on their SO with someone else in the cast, whether they "pretend" to be cheaters/hide the relationship even though they are okay with their SO having other partners, or are actual cheaters. Would love to see the SO "find out" whether it's part of the scene or because someone's been sloppy."
