Get the upper decker double deluxe blumpkin mug.A man takes the upper-back of the toilet off and sits on it. A woman gives him a blowjob as he takes a crap in the back of the toilet. After crapping and the blow job is done, he puts the lid back on the toilet.
An unsuspecting person comes in later and uses the toilette. When they flush the toilet it fills with brown water from the crap the man took in the upper deck.
