Expanding the pond is when you have someone spread their asscheeks for you, making their taut asshole available. You’ll need both hands for this next part. To expand the pond, you push both of your hands inside the asshole and then from the inside spread the asshole wide open. This is expanding the pond. Once you’ve done this, a second person can now come in and fist the person who’s pond is expanded more easily.
