Over the years I've swallowed urine on many occassions without ill effect. Maybe a little nausea after I've drained several full bladders in a short period of time.
At a recent bi-sexual group event, several of we subs were taken to a large shower room, directed to kneel while a number of male and female dominants pissed in our open mouths. At points we were directed to hold a mouthful then share it with the male or female at our side. That was hot.
I find swallowing a mouthful of piss a serious turn on. And there's that wonderful feeling you get when a master empties his bladder deep inside your ass.
On the other hand, scat whether vomit or feces is not a turn on to me and I wouldn't even consider it. It's a serious stomach churning health risk.
There's obviously a market for scat. Take a look at
