be quiet and jack off while watching her

You decide not to interrupt her. You watch her playing with her pussy in the pool. Your dick is getting hard and you start rubbing it through your pants. After a few minutes, you pull your dick out and start stroking it. You have a raging hard on now. Your eyes are glued to her, her enormous tits bobbing in the water...you hear her moaning softly. You imagine what it would be like to fuck her.
