Double Piss Filling XXL - First Catheter Treatment for The User

The patient urgently needed a lot of fresh piss, so I put his first catheter in and filled it with spit and my delicious pee. Meanwhile the bag of the catheter was already well filled. So off with it and through the open gag, administered his own piss. He didn't really want to, although it's so good for him, so I helped a little bit so that everything ended up in his mouth where it belonged. Would you swallow your piss voluntarily, or would I have to help too? It's not as tasty as my liquid gold.
