Vomit bath and shitting scat diaper
I'm so full I ate way too much, like a pig. I put on a diaper and shit in it, give a dirty blowjob with a black dildo, and puke everything inside me into a bowl; I fill the bowl with vomit and, being the dirty girl I am, I pour the bowl of vomit all over myself, making a huge mess of puke, shit, and diapers.
