King Calvin and King Mark, the self-proclaimed "Ballbusting Kings," deliver a raw and intense CBT session. They start by fondling each other's balls, the heavy nuts swinging between their legs. Mark initiates the pain, clenching his fist around Calvin's balls, making him wince. Calvin reciprocates, applying pressure, their grunts filling the room. They take turns, each trying to outdo the other, their balls turning a shade of red from the intense pressure.
