The aroused guy didn't get flustered in the dark and started jerking off, cumming all over the floor

Finding himself in a tough crisis situation - total lack of resources, pitch-black darkness, and all his gadgets dead - the guy didn't lose his shit and grabbed the closest and most reliable thing available: his cock. He gave it a thorough test-run: checked the idle stroke, then made sure it could still fire real shots. After successfully erupting and covering the entire floor with cum, he finally calmed down and realized that things aren't actually that bad.
