"Pepper and Odete are having an affair and take it underwater"
Finding the jacuzzi too constraining to contain their growing passion, the sisters' intense desire for each other spills them over into the pool, proper. It seems as if even the brief act of getting out of the jacuzzi and getting into the pool is too long a time for them not to be pleasuring each other, but somehow they manage to pry themselves apart long enough to grab some goggles. As soon as they hit the water of the pool, though, they can't keep their hands (or anything else) off each other as they take the action under the surface. Once underwater, it's a free for all, with each sister trying to gain the "upper hand" in their love play over the other.
