The girls are hosting a party in their garden and brought their human toilet. He has to wait under the toilet chair and has a big funnel in his mouth - this way he has no chance but to swallow all of the piss. One after another the girls sit down on the toilet chair and pee into the funnel. It's way too much for the slave to swallow it immediately and you can see their yellow piss piling up in the funnel. But these girls won't let him off the hook that easily - he'll have to swallow all of it!
