Do they react with each other? I really don’t know at this point. Just think maybe molasses is sticky and milk in rectum will cause diarrhea anyway for over 15 minutes, so I guess you referring to it as “sticky diarrhea-causing liquid is well mixed and shoved down the larger intestine, result in long-lasting diarrhea”? If my thought is right, then sure it’s a good punishment for a sperm-disliked 50-year-old slave wife like this (she did sucking, jerking, titty fucking, pussy and anal fucking contents like super rare, and none have swallowing semen scene).
She is over 40 now therefore has more fat in body. But overall looks not so fat unless she does the squad position or lay on ground with legs put high.
