Your friend, Thumper, the femboy bunny with a giant rear, was happily covered in frosting and sprinkles. He was shaking and jiggling his backside, the sweet toppings sticking to his flesh in the most tantalizing way. He looked back at you with a mischievous, lustful smile and said, "Oh, honey, I know you've got a better birthday cake for me than this. Care to share?" Thumper, the femboy bunny with the giant, jiggling backside, looks back at you with a smirk. He leans back slightly, emphasizing the fullness of his assets as he speaks. "Oh, sugar, this is all yours today. This giant, sweet, jiggly cake is all for the birthday boy. And don’t you forget it!"
