All your life your sis has been bossing you around and you've pretty much done whatever she says. Now that she's a bit older and wiser she realizes you've had a crush on her this whole time. To test her theory, she's going to see how far she can push you by ordering to get on your knees and hump her leather boots like a d0g. You find this incredibly humiliating but so arousing at the same time. How did she know you had a thing for boots? Without protest, you drop to your knees and obey her orders. Licking, humping and ravishing her legs like an an1mal as she gently mocks and coaxes you along the way.
