A lone, adventurous amateur dares to dive into the world of CBT, documenting his solo exploration for our eyes only. He carefully wraps elastic bands around his hard cock and sensitive balls, each loop pulling taut, stretching his skin to its limits. His strokes become feverish, the pleasure-pain sensation driving him wild. He bites his lip, his body tensing as he fights to hold back, but ultimately surrenders, his body shaking as he comes undone, the elastic bands still secured around his intimate parts.
