Serena Williams is obviously so impressed with her own ass that she can’t take her hands off it. She’s got the deathgrip on that sucker. Is she honking it? Is she making it talk? It’s like it’s got a life of its own, it’s that big. I half expect it’s a parasitic organism, kind of how Voldemort was living of the back of Professor Quirrell’s head. Notice how no one’s looking at where her hands are? She Who Must Not Be Named strikes fear in the heart of all who gaze upon Her.
