A lone figure, shrouded in the dim light of his private sanctuary, delves into the forbidden depths of self-pleasure. His cock hard and aching, he inserts a glass sound into his urethra, feeling the cool, smooth glass fill him entirely. He works the toy in and out, his breaths coming in ragged gasps as his body responds to the unique stimulation. His cock leaks pre-cum, his balls tighten, and with a final, powerful thrust, he pulls the sound free, sending him careening over the edge. His cock pulses, sending wave after wave of hot, creamy cum onto his waiting hand and stomach, his body shuddering with the intensity of his release.
