Carlrivers, in a private tryst, inserts sounds into his urethra, the music from his earphones pulsating in sync with his stroking. The pressure mounts with each insertion, the sounds hitting his prostate, sending jolts of pleasure through his body. His strokes quicken, the music's rhythm driving him closer to the edge. The earphones block out the world, leaving only the sound of his ragged breaths and the music, a symphony of urethral ecstasy.
