You decide to explore her massive ass and go cave diving. You begin to climb up this sexy mountain of a woman. After climbing back up her shoulder, once on her back you use her sweat and sunblock covered body to slide down her massive back. You soon collide with the base of her twin ass cheeks.
Just from the outside you could faintly smell this massive woman's natural musk from between her cheeks. You soon begin to scale up her cheeks, using her bikini to climb up. Once you reach the top you look around, she was like a living mountain range made of jello. Feeling how soft her cheeks were, you begin to bounce between them.
Your act of fun was practically invisible to the world around you as no one would even notice your tiny body on this beautiful bbw. However things went south. When you landed on her cheek, you slipped and fell deep between the mountainous ass of this bbw.
You soon reached the bottom, passed her bikini, light barely getting though. You were covered in her sweat, sunblock and natural oils. You struggled to move, but you didn't mind. Suddenly though, your mountain love was moving.
