When you both inevitably need to take a diarrhea shit, do it at the same time, with the submissive sitting on the bowl and the dominant sitting on the opened top tank. During the shit, the submissive will perform oral sex on the dominant. When the dominant finishes on the submissive’s face, they must punch the submissive in the nose to create a mixed fluid of blood and ejaculate on their face. Once both parties complete their shit.
