while having anal sex with your girlfriend or wife or even a male friend depending on how you are, simply after a good long screwing of the butthole I'm talking about 20 minutes a least pull out and her/ his butthole will be about 2 inchees in diameter, take a air compressor and strap a dildo on to it for her/ his saftey. Make sure the psi guage is at about 200 psi and let her rip, in doing so shit should come EXPLODING out.

advice if you are a proffesional in doing this stunt make her eat spicy Indian food for a week straight and it will be one crazy mess. !warning! my advice is to wear goggles at all times beacuse my friend has ben permanetly blinded in his left eye
