Del struggles and bucks but cannot dislodge the 240 pounds of female muscle sitting on top of his stomach. Jana realizes that when he bucks, her landing on top causes Del to let out an "oomph" when she lands. Taking delight in this, she bounces her weight heavily on his belly. Her butt lands with a resounding smacking sound each time she lands. Del is getting quite stomach ache from Jana sitting and bouncing full weight on his belly.
