In the dimly lit room, Rivmar13 begins a private dance with his own body, his hand wrapping around his thick, veiny shaft. His thumb swirls around the sensitive head, smearing pre-cum, as his other hand reaches down to caress and tug at his heavy testicles. The sound of skin slapping against skin fills the air as he picks up the pace, his breath coming in ragged gasps. His muscles tense, his abs contracting, as he fights to hold back, but it's no use. With a final, powerful stroke, he comes undone, his cock pulsing as he spills his load, his body shuddering with the intensity of his release.
