Berlin's kinky underbelly reveals itself in this solo gay scene. The man starts by injecting saline into his cock and balls, his body responding with a mix of pleasure and pain. His flesh stretches, his skin tightens, and his erection throbs. He then turns his attention to CBT, his hand working his sensitive flesh with increasing vigor. The room echoes with his moans, his body gleaming with sweat as he pushes himself to the brink of orgasm, only to pull back, teasing himself in a dance of denial and desire.
