>>211607136I unironically asked a fat friend (who are still moderately overweight back then, not as big as op pic but still a big guy) about this specific question. He said that his dad replaced their home toilet with that automatic sprayer thing that could spray water to your ass and do the job, you know something like mall toilet. But it was back then, in 2018, I heard that he's getting more and more fatter these days and unable to leave home for a long time
