During anal sex, the bottom partner defecates on the bed right before the top partner has to cum. Top partner then ejaculates on fresh steaming shit and feeds it to bottom partner.
when two people have anal sex and are in to eating each other's feces. it's called a swiss roller because the poop with semen looks like a little debbie swiss roll.
