Domina Fernanda Rodrigues just got a new mattress, and she has been dying to test it. She bounces on it with her sub Tammy, laughing, until she's ready for the real game. Then she orders Tammy to lie down and stay still, and the butt jumps begin: higher and higher, Fernanda landing on her sub's body with her full weight and that big, round butt. It's hard, it's intense, almost too much, but Tammy stays put, secretly loving every landing. Crazy high jumps, total surrender.
