When you place your dick in a hard taco shell, cover it with hot sauce, and then jam it into your partner forcefully causing the shell to explode into a hundred pieces. The hot sauce in combination with the razor sharp tortilla fragments will cause your partner to let out a high pitched squeal.
My girl loves a good mexican squealer bro. Not only does she like the hottest hot sauce, she also likes diced jalapeƱos on top so her panucha burns for days!
