I have a very powerful ass if you ask Me. I get it nice and oiled up. Like TONS of oil. So much that it's practically dripping from My cheeks! I clench them as strong as I can! Over and over at varied speeds, rocking My hips forward with each clench. Pushing My hips back and then really thrusting into each strong clench. Oily clenching, that's what we're talking about!
