I like to have my ass stretched out until it's gaping. use a speculum to hold it open if necessary. I put my rim seat up on blocks. get under it and put my ass up to the opening. That way you can put your full weight on the seat and our holes will be connected. very comfortable for us both. You sit on my ass. hole to hole and shit a turd into my gaping hole while you piss down into my open mouth. after you're done shitting i like to plug my hole and let it cook inside for a while. I've kept another man's shit in me overnight before.
