We wouldn't play this game if there were strangers (to us) in the group. It could be a whole lot of fun with say four to six couples who know each other well enough. It would be even more fun if everybody changed partners every so often. The most fun would be when the two of us hooked up together at the end of the party.
Mr. Alura is straight but doesn't get offended just by touching another man. A simple "excuse me" would solve that. Mrs. Alura... well, she'd probably go with the flow...
Now, how about a "Daisy Chain" during this little party? <EG>
Alura
Edit: Spoo, I can guaran-damned-tee you that nothing would happen to Mrs. Alura in that room that she didn't want to happen whether it was dark or like the noon-day sun.
