For those who don't understand Spanish. The girls at the beginning are complaining and not so willing to strip, but the guys (out of focus) encourage them, and remind them that they (the guys) already did the same, and let the girls recording them. The cute one is the more willing to strip, but she says that she will keep her hands covering her goodies. Obviously the guys complain, but at the end it doesn't matter what the girls want, because as they walk on the river rocks, they have to use their hands to stay on feet. This is one of my all time favorite clips.
