Yes (Lewd +1)

"I guess we can give this swinging thing a try...but we'd have to have some ground rules for both of us to follow, so we don't jeopardize our marriage." You acquiesce, hesitant but also slightly excited by the prospect.

"Mm, I agree...let's try to brainstorm some right now and put a note up on the fridge. If either of us thinks of anything else, we can add it to the list of rules anytime before this Friday." Ada hops off the couch and disappears into the study, returning with a marker and a piece of paper. The two of you sit down and have a healthy discussion, coming up with some basic rules. Come Friday, the list looks pretty well-thought out and comprehensive:

1. Always keep each other in the loop - ask for permission, not forgiveness!
2. No means no, if anyone is uncomfortable, we STOP! No questions asked!
3. Always use protection! No bareback sex, we don't want STDs or worse, kids :O
4. Spouse's comfort over partner's, always prioritize each other over any outside party's preference!
5. No heavy drinking or **** when experimenting, we don't wanna be too plastered to follow the rules!
6. Mutual respect! No humiliating or disparaging each other in front of our partners, even as a fetish or a joke!
7. NO CATCHING FEELINGS FOR ANYONE ELSE!

The list is littered with scrawls, underlined words and emojis courtesy of Ada, making you chuckle. It was nice that she was trying to keep things light-hearted, in spite of the serious nature of the matter being discussed. Fairly confident in your preparations and only slightly nervous, the two of you go about your week until Friday night arrives.
