Infidelity challenge
1. A & B are an established couple
2. A is somehow switched with his/her AU counterpart who is alao partners with B's counterpart. Easiest example: Daniel is involved with Jack; he somehow changes places with Daniel from Earth2 who is involved with that universe's Jack. Follow me?
3. A has an sexual encounter with his counterpart's
lover. Mutual or non-con is up to you.
4. After A returns to own universe/timeline, B learns what
happened. B considers it infidelity; A agrees? disagrees?
Where do they go from there?
