During intercourse, female breast milk and male ejaculate is collected with a ladle, then put
in the freezer over night,
the next day, said ladle is inserted into a bodily orifice (e.g anus, vagina, mouth) until it melts, it is then drank out of the bodily orifice by the partner with a silly straw and then puked onto the chest of the opposite partner.
NOTE: for extra pleasure
donkey punch during any step.
