I need some games for 2 young couples?

me and my friend went to Banff last spring and met 2 girls, coincidentally, 2 new couples formed. we are thinking of going back there this summer, and i was thinking we could play some games, games that involve a little sexuality, but i cant think of any. what would be some fun games that involve a little touching? I'm not looking to go too far though, no full fledged sex games please.
