After the man has loaded up on a hearty supper, it is time for him to go and participate in the act of intercourse with another woman. When the man gets over to the girl's house then they should start having sex and he should make sure that the girl is ready to be penetrated in her vagina. (The man should have eaten his meal approximately 3 hours prior to the encounter) once he feels fecal matter starting to be produced, he should poop just a tiny bit so that it comes out at around 4 inches away from his butt-hole, then he gets the liquid nitrogen and dips the poop, which should still be clinging to his anus, in the vat of liquid nitrogen. From this stage he must lay the girl on a bed, and then stick the poop into her, if he wants to let her decorate the piece of fecal matter with a marker, crayon, or etch a design into it, then so be it (it is highly recommended that she puts ribs into it for that extra pleasure. Once the fecal matter is inserted, he should then push his pelvis back and forth while having his hands in front of him, moving them back and forth to the rhythm of the humping (keep them in front of you for safety purposes). Once the girl is about to cum, he should stop, put it in as far as possible, and break off the piece of poop, which will end up space docking
