The Rhythm Game
To play this game, you need to record a CD where slow-paced songs alternate with faster-paced ones, as long as you like them and they're appropriate for the occasion. The only rule of the game is this: while the slow-paced songs are playing, you can't touch the other person; no physical contact. You can talk or do whatever you want, but no touching. On the other hand, while the fast-paced songs are playing, anything goes. Try the game, and you'll see how the 'heat' rises as the songs play. This way, you'll have fun in a different and very prolonged way.
Needless to say, you can rewrite the rules of the game to your liking, choose other types of songs... As always, let your imagination run wild.
