Take a shit and put it in the freezer 6-12 hours before feces is probable. Remove feces from freezer. Have your person of choice (female in this writers mind) bend over naked spreading their butt cheeks. Promptly lubricate the other persons brown eye, align the feces for entry and shove until completely disappeared into the persons rear. Allow the feces to thaw, than lead your partner to the toilet, while they are evacuating your feces have them preform fellatio on you. If freezing is a non option for your partner the use of a piping bag is acceptable.
When my girlfriend said she wanted to experience a brown hopper, I thought it was gross at first but after words we both decided she needed pooindahole every night.
