Big Mac and Sugar Belle have been married for about two years now, and it's not like they have a bad marriage or anything. They never fight, they always work together, and they still genuinely love each other. As nice as it is, though, it's gotten a little repetitive... maybe even boring...

That's when they decide to attend a swinger party, but even though Sugar Belle gets paired up with somepony she'll probably enjoy, Big Mac gets paired up with the last option anypony wanted. The real question now is, will Spoiled Rich ruin Big Mac's night, or will Big Mac ruin hers? Or will they both cum?
