John Mwaki's verification video is a masterclass in anticipation. He begins by running his hands over his chiseled abs, his touch igniting a trail of goosebumps. He turns, giving a tantalizing view of his bulge straining against his jeans. He doesn't touch it, not yet. Instead, he leans in, his breath hot on the camera, whispering, "This is just the beginning," before the video cuts to black, leaving viewers aching for the promise of more.
