Nagasaki Blazer

The act of enjoying a sushi night with your spouse, heading back to your home and then later engaging in sexual intercourse, and right before climax, you create a volcano with onions and light it on fire, similar to what one would do at a Japanese hibachi steakhouse, and rather than using water to put it out, you place the burning volcano on your spouses ass, and but out the fire using the semen extracted from your climax.
