Every sub knows Rhianna's reputation, and I'm about to see why: once she starts, she does not stop. The blonde top dominatrix, in a shiny black latex corset and thigh-high boots, has been waiting since the morning to prove it again, and Flavinha, in pink, is today's lucky face. Rhianna sits down, grinds, rides, shifts her weight and keeps going, relentless, unstoppable, taking exactly what she wants. It is overwhelming, right on the edge, and Flavinha melts deeper with every move instead of looking for a way out. Facesitting by a queen who never gives up her throne.
