Parallel world

I am staying in a Wellness Hotel together with my wife for a nice weekend. Hotels always makes us hot, so we have intensive sex. As we lie in bed to recover, we hear noise from the room next door. We smile as some other couple seems to have fun. We start to wonder WHO the couple is. As we go downstairs to have dinner, we take a closer look at the people in the hotel. We try to figure out WHO the couple making noise next door was. We start having eye contact. There are many stories behind the faces...
